Top 10 Best Air Purifiers in 2018 List

1) Rabbit Air MinusA2 – Our 2018 Winner

After testing hundreds of different air purifiers, Breathe Quality is proud to announce that Rabbit Air MinusA2 is our winner as the Best Air Purifier in 2018.

And why we consider it the best air purifier system for home available in 2018?

Rabbit Air is one leader in the US air purifier market, starting from 2004. Their Rabbit Air MinusA2 Ultra Quiet is the latest air purifier product to compete in the mid-range air purifier market. To perfect this product, Rabbit Air created a 6-stage purification & deodorization system to make the cleanest, freshest air possible in the world. Let’s dive into the power of this best air purifier.

1. Pre-filter – The polluted air must pass through a pre-filter, there it will capture all large particles, along with dust mites and some of pet hair.
2. Medium Filter – Traps large pollen, pet dander, mold and dust particles that is small enough to bypass the Pre-filter.
3. Advanced BioGS HEPA Filter – It is a True HEPA Filter that captures 99.97% of all allergens, virus particles, pollen, mold and fungi particles down to 0.3 microns. Rabbit Air advances their air filter process, therefore prolong optimal filter efficiency and filter life of their HEPA Filter.
4. Customized Filter – Double the protection with a variety of customized filters for specific needs like Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber.
5. Activated Carbon Filter – Eliminates odors, smokes and chemical vapors.
6. Ion Generator – The last line of defense is an ionizer to capture even the tiniest particles of pollutant and trap them into other filters. Can be switched on/off.

As you can see, Rabbit Air MinusA2 is extremely powerful because of these 6-layer filtration, while common air purifier only make use of 2 to a maximum of 4 filters for air purification. However, this air purifier doesn’t just show off lots of air filters. The bottom line is the high quality of each filter in MinusA2.

Rabbit Air MinusA2 is the first air purifier to use not only one but twice the pre-filtration. With both the Pre-filter and Medium filter, it will reduce most of large and medium pollutant objects. Remember that the pre-filter of MinusA2 is washable and permanent to use.

Through the double pre-filtration and thanks to the Advanced BioGS technology, the True HEPA filter will only need to capture the as small as 0.3 microns particles. Most importantly, it increases the efficiency and life time of MinusA2’s True HEPA filter so it can last up to 2 years. You will profitably reduce the cost of HEPA Filter replacement.

Expert tip: Why you need True HEPA filter instead of normal HEPA filter? Why you need to replace it? Find your answer in this article.

As a double protection layer with True HEPA filter, Rabbit Air MinusA2 add a Customized filter. If you have serious allergies or asthma for a specific reason, you can tailor to fit your needs. Each filter (Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber) is specially engineered to trap and reduce different types of germs, chemicals, odors and allergens.

As the last line of defense, the Ion Generator will remove even the tiniest particles of pollutants by trapping it back in other layers. We have recorded that the amount of ozone is about 0.002 ppm, which is 25 times less than the 0.05 ppm maximum ozone safety standard set by California Air Resource Board, so MinusA2 will never irritate asthma and respiratory issues. However, if you don’t like this function, you can easily turn it off with a simple button.

Overall, on a scale of 0-10, we will no doubt give Rabbit Air MinusA2 a perfect 10 score. We also gave survey to hundreds of people who suffer from serious allergies and asthma and asked them the before/after using MinusA2 experience. 100% of them rated MinusA2 as the life saver. It is incredible, right?

Rabbit Air MinusA2 is not only powerful inside, it is beautiful outside. You can choose the front panel from many different artistic design choices, from Vincent Van Gogh, Claude Monet, Katsushika Hokusai to original designs by Rabbit Air’s creative team. Moreover, you can mount this air purifier on your wall, making it a perfect art.

MinusA2 comes with three editions. The first is SPA-700A, which covers up to 700 sq ft (around 65 sq m). The bigger (covers up to 815 sq ft) has two editions: SPA-780A (with no wifi connection) and SPA-780N (wifi enabled). With Wifi enabled, the SPA-780N can be controlled via an iOS application.

Fun facts: the model name give you exactly the area it can cover, for example, SPA-700A covers 700 sq ft and so on.

One more thing we will love this air purifier is because of its silence. To reduce the noise level, instead of decreasing the air filters, Rabbit Air improves their fan with an advanced technology. You will have a both quiet and powerful air purifier, all without a need for regular maintenance.

If you still have doubt for this air purifier, you should look below. Thanks to the low power consumption, a long-term investment in Rabbit Air MinusA2 will reduce both the annual filter cost and energy cost of you.

Here is the pros/cons of Rabbit Air MinusA2

Rabbit Air also provides another good air purifier that we will certainly save a slot in this list if not for the MinusA2: the BioGS 2.0 SPA-625A. This air purifier is also powerful with the BioGS HEPA Filter technology from Rabbit Air in 2018, with a cost of nearly half of the MinusA2. With a 4-stage air filtration and a coverage of 625 sq ft, Rabbit Air BioGS 2.0 is still a good air purifier to pick.

Are you convinced? If yes, please check the review of Rabbit Air BioGS 2.0 SPA-625A.

2) Hamilton Beach 04384 – Best Starting Air Purifier under $60

It is hard to find a good air purifier under $60 in 2018. Most of the air purifiers under that range are either ionic filters with high ozone emission or cheap material.

Hamilton Beach is a trustworthy brand for home accessories since 1910. They invented the Hamilton Beach 04384 with the idea to make it last as long as permanently. And with this idea, Hamilton Beach 04384 is truly a best starting air purifier that you can find under $60 budget. In this air purifier, you will have:

1. Permanent HEPA-type Filter – This HEPA filter works like other high-end machine’s pre-filter, and can capture most of the large objects like pet hair, large dust and pollen.
2. 2 zeolite Activated Carbon filters – Targets pet odors and cooking smell.

What if you are looking for your first-time air purifier, and finding out that most of the HEPA Filters must be replaced once per six months. You are not willing to spend about $50 for annual air cleaning. Then it’s time you need to look for Hamilton Beach 04384. Though the HEPA is not certified to be as effective as others, we can guarantee that it works. This filter is permanent because it you can vacuum or wash it.

As a low-end device, Hamilton Beach 04384 won’t have any Smart features. Even for a solid-built air purifier, due to cheap material, Hamilton Beach 04384 still emits a burning smell after long time using. To avoid it, you need to clean the permanent HEPA filter regularly. Also, it will help reducing the noise of this air purifier.

This air purifier is designed for personal use as it is really lightweight and small-size. For room coverage, it will be effective for 100 sq ft.

Here is the pros/cons of Hamilton Beach 04384

You can purchase the normal Hamilton Beach 04386A – with the same technology as the Hamilton Beach 04384, only without the Activated Carbon filters. Though it can’t help you remove pet odors, it is a reasonable solution for pet hair.

3) Levoit LV-H132 – Best Portable Air Purifier under $100

Fun fact: Levoit LV-H132 Air Purifier is the #1 2018 Best Seller Air purifier in Amazon.

Why Levoit LV-H132 is so popular? Because for a low-range air purifier under $100, this portable air purifier has no rival in terms of performance.

Levoit is a great brand of air purifier with their favorite quote: “One less snooze = a morning walk around the block”. As their most favorite air purifier in the market, Levoit LV-H132 comes with a 3-stage Air Filtration System:

1. Pre-filter – This fine preliminary filter is able to capture large particles of pollutants. You need to vacuum this filter regularly because it is only effective for a short time.
2. True HEPA filter – A True HEPA Filter can reduce 99.97% of down to 0.3 microns dust mites allergens, virus particles, pollen, bacteria particles.
3. Activated Carbon Filter – It is great at eliminating odors and smoke in your home.

There are not many certified True HEPA air purifiers in this low-range segment. More than this, the performance of LV-H132 is about 10% better than other HEPA-like filters, and therefore is a best air purifier for price. If you have serious problems with allergies and asthma, or you just want to an affordable best device, this air purifier is right one for you. Its True HEPA filter meets the strictly requirements to remove 99.7% of dust, smoke, odor, mold spores, pet dander and particles as small as 0.3 microns.

LV-H132‘s design is small and elegant, with 2 main color editions: Black and White. This compact True HEPA Air purifier is mostly suitable for small bedroom and personal use. The room coverage of LV-H132 is only 86 sq ft.

We believe this air purifier is one of the best for your babies. The Nightlight function and Quiet Mode of LV-H132 is really great to bring a safe and sound sleep to your children.

Here is the pros/cons of Levoit LV-H132

If you are willing to spend $200, Levoit has introduced their latest air purifiers – Levoit LV-PUR131, Levoit LV-H133 and Levoit LV-H126.

LV-PUR131 has a Smart Sensor called Air Quality Indicator to adjust the fan speed according to the surrounding air quality. You can also enjoy other smart features and a large room coverage of 322 sq ft.

LV-H133 is the ambitious move of Levoit to approach the mid-range segment. This air purifier increase more fan power into a higher CADR, and as a result, cover a larger area of 538 sq ft. If LV-H132 is a perfect for your bedroom, this LV-H133 is even more silent than the predecessor.

LV-H126 is the last member of Levoit family. This compact air purifier is mostly used as a personal air purifier and would need more tests to decide if it can win over the LV-H132 as the Best portable air purifier under $100 or not.

4) GermGuardian CDAP5500BCA – Best Deal for limited time in 2018

The low-range segment is always the most competitive field of air purifier market. In this segment, Guardian Technology rises as the most well-known name for affordable air purifiers. As an US brand for manufacturing a variety of products ranging from air purifier, humidifier to spa therapy, their products – GermGuardian air purifiers are always staying high in the consumers’ list for many years (currently they have 2 in top 20 Amazon Best seller for Air purifiers).

Fun fact: Guardian Technology allows dogs in their office.

GermGuardian CDAP5500BCA WiFi Smart 4-in-1 is the latest product in 2018 of this brand. This device is currently the best one of GermGuardian using the powerful 4-in-1 Air Cleaning System. Also, you can find GermGuardian CDAP5500BCA with a best deal of under $200, for a limited time. Let’s see how we get with this air purifier:

1. Pre-filter – Like above air purifiers, GermGuardian CDAP5500BCA has a pre-filter to help remove the large particles of pollutants.
2. True HEPA Filter – Captures 99.97% of microscopic allergens, dust and mold spores down to 0.3 microns in size.
3. Activated Carbon Filter – Reduces odors created from smoke, cooking, and pets.
4. UV-C Light – Kills airborne bacteria, viruses and mold spores that cause health issues.

With a powerful 4-stage air filtration like this, it is unbelievable that GermGuardian CDAP5500BCA is under $200. This air purifier combines both the True HEPA filter and an UV-C Light to not just capture the pollutant objects but also kill the germs and bacteria inside them.

The performance rating of CDAP5500BCA is about 5% better than previous models like GermGuardian AC4825 or GermGuardian AC4300 thanks to the latest technology. While the statistic is not impressive, this air purifier’s power is nearly the same with the top rated ones in low-range segment.

To back up for the opinion that GermGuardian CDAP5500BCA is one of the best air purifiers list in 2018, we need to take a look at its Smart Features. GermGuardian is the only brand that add a Wifi-enable and Alexa-enable features for an under $200 air purifier. Their GT app is available with both iOS and Android devices.

As we stated above, Guardian Technology is the leader in low-range budget air purifiers. At the moment, they have 2 in top 20 of Amazon Best sellers for Best Air Purifier: GermGuardian AC4825E 3-in-1 Air Purifier and GermGuardian AC4300BPTCA 3-in-1 Air Purifier.

We coulld all agree that GermGuardian is the most popular brand for top rated best air purifiers in 2018. The inferior of GermGuardian air purifiers come with only a 3-in-1 Air cleaning system, however it is still one of the best air purification system with the UV-C Light filter combining with True HEPA filter and an Activated Carbon filter.

The GermGuardian AC5350B Elite and GermGuardian CDAP4500BCA WiFi Smart have 4-in-1 Air Cleaning system. Honestly, these air purifiers are nearly the same performance rating with GermGuardian CDAP5500BCA.

Here are some of GermGuardian air purifiers:

5) Coway AP-1512HH – Best for Performance and Value

Fun fact: In the last year vote for best air purifier at Breathe Quality, we select Coway AP-1512HH as the Best Air Purifier.

Coway is the number one in Korean Air Purifier’s market in 2018. As always in top of Amazon 2018 Best Seller for Air purifier, Coway AP-1512HH is a favorite air purifier with an amazing performance rating. We have seen lots of reviewers also speak high of this device.

Why is Coway Mighty Air Purifier AP-1512HH so highly rated in almost all of air purifiers’ reviews websites?

Mainly due to this important 4-Stage Air Filtration:

1. Pre-filter – A washable pre-filter will help you capture the large particles of contaminants, from pet hair, human hair and mold.
2. Activated Carbon Filter – This filter works its best to deodorize and trap harmful gas to keep your place fresh and odor-free.
3. True HEPA filter – The high-performance composite True HEPA Filter that captures 99.97% of down to 0.3 microns allergens, virus particles, pollen, mold and fungi particles.
4. Ionic Technology – Vital ionize can trap even the tiniest airborne particles and send it back to other filters. Can be switched on/off.

For a low-range $200 air purifier, Coway AP-1512HH utilizes a progressive technology like any $300-$400 air purifiers, such as Winix WAC9500 or Rabbit Air BioGS 2.0.

However, having a lot of air filters is just one side of the coin. The bottom line is the top-notch performance rating of this air purifier under the low-range segment. We have 3 clear winners when testing all under $400 air purifiers in 1 hour, and Coway AP-1512HH is one of them.

But the superior part of this air purifier is the smart features. Coway technology allows their air purifiers to automatically adjust the airflow speed based on the air quality level via Smart Sensor. Also, the unique Eco Mode technology can shut down the fan when it detected no air pollution, perfect for saving energy. With an already lowest power consumption, with Eco Mode, it is safe to say Coway AP-1512HH is a best for both performance and value you can get.

Moreover, the room coverage of this air purifier is impressive with 360 sq ft at maximum.

With a quite small compact size, Coway AP-1512HH is really high efficient. We even have one in our home, and after 7 months using, its reaction to odors and cooking smells is still one of the best.

Some reviewers complained that the display light on the top is too bright, and it can’t be turned off. It is true. So if you have problems with light, please do not set the air purifier in your bedroom.

No more saying, this is the best value air purifier you can get in low-range budget.

Here is the pros/cons of Coway AP-1512HH

It’s hard to find a Coway’s fan without using Coway AP-1512HH, but to give a honest review for the best air purifier, we will give the last two items of them. Coway AP-0512NH is also a compact like AP-1512HH, but with a smaller size and smaller coverage. Comes with Therapy 6 Sounds developed by Doctors, this one is the most suitable for baby’s bedroom.

Coway AP-1216L Tower is a tower air purifier, only cover a smaller of 330 sq ft. The Technology of Coway AP-1216L is basically the same with AP-1512HH.

At the moment, Coway builds the new air purifier brand named AIRMEGA. These products are mostly for mid-range to high-range segment. Let’s take a look at these AIRMEGA 300S and AIRMEGA 400S to see if it could fit you more than the Coway AP-1512HH.

6) Honeywell True HEPA Allergen Remover HPA300 – High Performance Rating

Fun fact: Honeywell is claimed to be more than 130 years of Innovation.

Honeywell is not just an air purifier’s brand. In fact, this Fortune-100 company invents and manufactures technologies for a lot of world’s challenges like energy, security, productivity and so on.

Honeywell HPA300 is a powerful device with only 2-stage air filtration system:

1. Pre-filter – The pre-filter has Activated Carbon filter in it. This will both help absorbs VOCs, gases, odors and traps larger particles.
2. True HEPA filter – The powerful True HEPA filter can capture up to 99.97% of as small as 0.3 microns pollutant particles like pet dander, mold, viruses, bacteria and pollen.

There is no doubt that Honeywell is using the best True HEPA filter technology in the world. With only one layer of True HEPA filter, Honeywell HPA300 is still on par with Coway AP-1512HH in terms of power. As we can see below, this True HEPA filter is capable of capturing the 0.005 microns viruses.

To reduce the size of this air purifier container, Honeywell has combined both the pre-filter and activated carbon filter. However, this pre-filter needs to be replaced after 3 months. This is a big minus to Honeywell HPA300 because of the high filter replacement cost.

While standing in the low-range segment, Honeywell HPA300 utilizes a very high fan power, as well as a fantastic CADR and ACH that surpasses even the mid-range air purifiers. As a result, this machine can handle a very large area up to 465 sq ft.

Unfortunately, this air purifier has a high noise level due to the powerful fan. And while being the high-end machine of Honeywell, Honeywell HPA300 lacks of many important Smart features.

Our verdict is Honeywell HPA300 is still one of the best air purifiers we’ve put through its paces to date, earning even good reviews praising its build and performance versus cost. Additionally, the price is coming down due to the fact that there is new flagship named Honeywell HPA600B for mid-range space.

Here is the pros/cons of Honeywell HPA300

Review: Honeywell HPA300 Review.

Related post: Best Air Purifiers for allergies and asthma in 2018.

If you find 465 sq ft is not necessary, Honeywell provides a variety of selection for air purifier, being the smallest HPA100 (with 155 sq ft) and the medium HPA200 (with 310 sq ft).

Basically, all Honeywell’s products share the same technology, only different for the size and the room capability. So before purchasing any Honeywell’s products, please check your room’s area again. Down there is all of Honeywell’s product available for you: HPA 060, HPA100, HPA160, HPA200, HPA250B (can connect with Bluetooth).

Fun fact: The model names of Honeywell give you exactly the room capability of air purifier (higher means larger). The white-version’s name is the black model number plus 4. Example: if Black model is HPA100 then White model is HPA104 and so on.

7) Winix WAC9500 – Best Solution for Pet Owners

If you have pets at home, you must encounter more than one time the pet problems like pet hair, pet odors and pet dander. We all love our pets, but we need a solution.

As an Amazon’s Choice for Best Air Purifiers, Winix is also a must-look brand when finding an air purifier for your home. And for the common problems of your pets, Winix WAC9500 is safe to say the best.

1. Pre-filter – This pre-filter will help capture the large objects of contaminants, such as pet hair and even some kinds of pet dander. Just like other high-end machines, the pre-filter is washable to be permanent.
2. True HEPA filter – The True HEPA Filter that captures 99.97% of down to 0.3 microns allergens, virus particles, pollen, mold and fungi particles.
3. CleanCel Anti-Bacterial Treatment – Though this is not a physical filter, the treatment also provides a layer of protection to your air quality.
4. Activated Carbon Filter – This Activated Carbon filter will eliminate odors and smokes, also reduce the common household chemicals.
5. Winix PlasmaWave Technology – The last line of defense, which can further reduce the amount of pollutants. Can be switched on/off.

Winix WAC9500 features the unique technology of Winix – PlasmaWave, to produce both positive and negative ions (plasma state). Combined with True HEPA Filter, PlasmaWave technology can eliminate effectively most of toxic contaminants. However, not like the ionizer filter, it won’t irritate asthma and respiratory issues. That’s why PlasmaWave is considered the safest technology to combat with the smallest bacteria.

For performance rating, Winix WAC9500 has equal power with the last year’s Best Air Purifier Coway AP-1512HH. PlasmaWave technology is proved to be the strong competitive edge of this brand. Moreover, Winix WAC9500 brings CleanCel Anti-Bacterial Treatment to further destroy the bacteria.

A high-end machine like Winix WAC9500 must have Smart Sensor to automatically adjust your air cleaner settings to meet the needs of your environment. We also like its remote controller, especially because of the hard-to-press buttons.

The AHAM verified room size of our Winix WAC9500 is 284 sq ft, which is a typical room of US.

The last but not least, Winix WAC9500 shares the same high ACH and CADR like Honeywell HPA300, but unlike the latter, the Winix device is really quiet. This difference will help you know which one to choose for your bedroom.

Here is the pros/cons of Winix WAC9500

Review: Winix WAC9500 Review.

Related post: Best Air Purifiers for pets in 2018.

Winix WAC9500 is one of the latest products of Winix, however, with some reviews of it is not worth the money, we will add some previous versions of this product so you can choose the one you love the most. The couple of Winix 5300-2 and 5500-2 (Amazon’s Choice) provide an only 3-stage air filtration, including of True HEPA Filter, Carbon Filter and PlasmaWave technology. The fact is that with around $200, this couple are giving the best performance/cost.

If you are a true fan of Wifi-enabled air purifiers, you may love the couple of Winix NK105 and HR1000. Both of them come with the latest 5-stage air filtration of Winix, and a great Android app – Winix Smart to control your air purifiers. But not like Rabbit Air, Winix wifi devices seem to disconnect randomly. If you are planning to buy one of the Winix Wifi-enabled, you must make sure to check it carefully.

8) Blueair Classic 605 – Best Air Purifier for Large Room

If you are still reading, you have already aimed at mid-range to high-range air purifiers. Air purifier is nothing but a powerful fan to suck in the air from your whole room. The more powerful the fan is, the more expensive your device will be.

In the mid high-range, it is difficult to tell the best air purifier, since there are so many potential candidates like AIRMEGA 400S or Austin Air HealthMate. After a lot of tests, we finally choose Blueair Classic 605 as the winner for large room.

Blueair is a powerhouse in air purifier industry, marking about 20 years in this market. It is not a surprise if you have heard the well-known name of Blueair. In Breathe Quality, the Blueair device representing the family to our readers is Blueair Classic 605. Let’s look at the powerful air filtration of this machine:

1. 3 sets of HEPASilent filter – Blueair’s unique HEPASilent filter combines electrostatic and mechanical True HEPA filter and Activated Carbon Filter. This incredible technology help you capture 99.97% of as small as 0.3 microns allergens, virus particles, pollen, mold and fungi particles. Also, this filter is perfect for eliminating odors, smoke and VOCs.

Only one type of filter will make you confused, but the HEPASilent Technology of Blueair is an effective combination of a high level True HEPA filtration, electrostatic and deodorization.

9) IQAir GC MultiGas – High-range representative

In this high-range segment, only the bulky machines which can cover a large area have a chance to compete in. IQAir is that giant, with the foundation to be 50 years ago.

1. HyperHEPA filter – The first stage of filtration features a powerful pre-filter, which can capture 99% of particles down to 0.3 microns, and 95% of particles as small as 0.003 microns.
2. Cartridge-based activated carbon filter – Made with the highest quality ABS plastics, this filter can remove VOCs and odors effectively.
3. Cartridge-based chemisorption – This stage destroys harmful chemicals, such as formaldehyde, by an oxidation process inside a chemically active alumina pellet.
4. Post-filter sleeve – A post-filter sleeve wraps each gas cartridge to prevent media dust from being released.

Instead of trying to prolong the life time of True HEPA filter with a pre-filter, IQAir GC MultiGas implement the HyperHEPA technology to increase the particulate loading capacity by 13%. As a result, your air filter will run for a good one year.

Next, their two cartridge-based adsorptions is responsible for destroying any harmful chemicals in smoke. This process is back up with an unique 3D UltraSeal no-leakage design to prevent air from escaping back into the room without being drawn through the GC MultiGas filters.

10) Alen BreatheSmart – Best for Customer Service

Our last champion in this best air purifiers in 2018 list is from AlenCorp company, where all of their air purifiers earned Consumer Digest’s Best Buy. While Alen BreatheSmart‘s performance in mid-range can’t compare with Rabbit Air MinusA2, their lifetime warranty policy deserves a slot in Breathe Quality’s list.

Fun facts: AlenCorp is the only company offering a lifetime warranty. Their motto is “put the customers first”.

Let’s look into the Alen BreatheSmart’s 4-stage air filtration:

1. The HEPA-Pure filter is the standard filter that captures most of the pet dander, mold spores and pollen.
2. The HEPA-Silver filter is perfect for mold, germs and asthma related concerns.
3. Next is the HEPA-FreshPlus filter to remove smoke, VOCs and heavy chemicals.
4. HEPA-OdorCell filter can neutralize pet and diaper odors.

With 4 HEPA and Activated Carbon Filter types, Alen BreatheSmart is capable of removing pollutant particles. Because AlenCorp said that they want to reduce the noise and the cost of air filter replacement, these filters are not True HEPA filters. Therefore Alen BreatheSmart isn’t the best option if you have serious allergies and asthma issues.

As a trade off, Alen BreatheSmart offers 15 panel color options including of white, blue, brushed bronze and stainless, black, rosewood, natural maple and more to match your personal style.

Also, we will still find the high-end Smart features in this air purifier, like Smart Sensor with a colored light indicator. It adjusts BreatheSmart’s cleaning power to achieve the best air quality while saving energy and maximize filter life.

One of the best functions of this BreatheSmart air purifier is the WhisperMax technology. It generates soothing white, pink, red noise that gently masks disruptive sounds for a peaceful night’s sleep. A great air purifier for bedroom, right?

Alen BreatheSmart is powerful enough to help clean air in a large area of 1100 sq ft.

It is fair to say with around $600, BreatheSmart is the flagship of AlenCorp. If you like their customizable color options, their BreatheSmart FIT50 is much quieter and have longer filter life than BreatheSmart. Or you save a little money for purchasing the BreatheSmart FLEX (without SmartSensor and WhisperMax technology).

If you don’t need customizable color option and don’t have budget for the Alen high-end best air purifiers, you can think of their old products like Paralda and T500. It can only cover an area of 500 sq ft (which is still huge for a common room). With their lifetime warranty, the customers could believe that their investment will be long-term.

Choosing the right filter types

The classic Air purifier comes with a HEPA filter. Some may have other filters for specific needs, here are the terminology and definitions:

Pre-filter – An essential feature of air purifiers that use a HEPA style filter. The pre-filter captures the large dust and pet dander to help prolong the life time of the main filter. Most pre-filters are washable and reusable and last a lifetime.

True HEPA Filter – This is the highest standard air filter you can get for a best air purifier. In order to carry this label, the filter must meet strict regulations set by the United States Department of Energy (DOE) and capture at least 99.97% of particles as small as 0.3 microns. A true HEPA filter needs to be replaced after 6 months to 1 year, and you should use the suitable replacement for your air purifiers.

Activated Carbon (or Charcoal) Filter – This filter can absorb odorous particles and gases. That’s why it can remove the smells produced by smoke, pets, cooking, chemicals, etc.

Ionic Filter (or Ionizer) – This filter emits negative ions to charge small particles like dust, pollen and bacteria and collect them into a plate.

UV-C Light – The Ultra Violet light destroy bacteria and virus by sterilizing them. The UV-C Light (UV Light type C) is harmless to human.

Advanced BioGS HEPA Filter – A technology from Rabbit Air, to help prolong the life of the main True HEPA filter.

Permanent HEPA Filter – A technology from Hamilton Beach, to make their HEPA-type filter be cleaned by vacuum, therefore you don’t need to replace their HEPA filter.

HEPA-type Filter – This filter is a lower quality version of a True HEPA filter and doesn’t meet the standards set in place by the U.S. DOE mentioned above.

Choosing the right size air purifier

It is highly recommended to check your air purifier’s size and room capability. The size of an air purifier is varied, and if you do not have room for your new air purifier, it would be a disaster.

Room capability, or how well your air purifier can cover is also a crucial factor. You know, air purifier is not an one size fit all machine. Most air purifier is designed for a small room of 100 to 400 sq ft. For a larger room, you will need an additional air purifier or larger coverage one. Otherwise your air purifier will not meet your demands, and cost you much more energy than normal.

Knowing some terminology in air purifier

ACH Stands for “Air Changes Per Hour”

The ACH rating, stands for Air Changes per Hour, tells you how many times the device can exchange the air within a room with clean, fresh air every hour. For example, 4X means the device cleans air four times per hour.

Common ACH ratings in best air purifier you’ll see are 4x, 5x, 6x, etc

Remember that the advertised ACH for air purifier is normally when you use the maximum fan speed.

CADR Stands for “Clean Air Delivery Rate”

Developer by the Association of Home Appliance Manufacturers (AHAM), CADR, stands for Clean Air Delivery Rate, tells exactly how well an air purifier can clean the air within a particular size room.

For example, an air purifier with a CADR like this: dust/500 cfm, pollen/640 cfm, and smoke/500 cfm (or 500 Dust/500 Smoke/640 Pollen) will normally have a coverage from 700 to 800 sq ft.
