Top 15 Best Air Purifiers in 2024 (with Ranking List)

1) Blueair HealthProtect 7770i – Our 2024 Winner, Top of the List

The Blueair HealthProtect 7770i is the best air purifier you can buy today, while the smaller (and slightly less capable) HealthProtect 7470i is so similar that we’ve lumped the two together.

Blueair is a global leader in the air purifier sector, having been in business for more than two decades. And the firm has exceeded itself with the debut of four new HealthProtect models last year, and if you are a fan of this brand’s Classic line, the flagship Blueair HealthProtect 7770i may be the best air purifier for you. It’s packed with power and comes with a stylish new design, though Blueair devices are still at the more expensive end of the scale.

1. Smart Filter – The ultimate Blueair HEPASilent Ultra technology effectively removes 99.97 percent of pollutants down to 0.1 microns, including pollen, dust, pet dander, mold spores, viruses, and germs. It will destroy viruses and bacteria rather than simply trapping them.

Why it’s the best air purifier 2024: We think the HealthProtect 7770i is a fantastic choice for you with one of the best air purifying technologies, phenomenal power, unmatched performance, a solid design and a whole host of other great features. The Blueair HealthProtect 7770i isn’t a cheap device with a price that, despite being cheaper than its predecessor from the Pro line, is still costlier than many competing flagships, but if you’re looking for the ultimate air purifier experience in 2024, you will be hard pressed to do better than this latest from the Blueair HealthProtect family.

As one of the few high-end air purifiers released last year, the Blueair HealthProtect 7770i can ensure you’re future-proofed when it comes to next-gen air purifying performance. The HEPASilent Ultra technology is more powerful than you’ll ever need, since it can remove and kill 99.97 percent of viruses and germs, dust, pollen, dander, and mold, as well as eliminate volatile organic compounds (VOCs) and smells as small as 0.1 millimeters. According to testing, the new HEPASilent filter cleans better than any H13 True HEPA filter while using 55% less energy and producing 10% less noise.

Additionally, we appreciate Blueair’s flatter look for the Blueair HealthProtect 7770i this year. It allows more air in, and the air purifier has a higher CADR rating, which outperforms all other high-end devices. It is capable of increasing the amount of pure air in every part of the space.

Not only does the Blueair HealthProtect 7770i boast an unmatched performance, but its smart features make it the best air purifier. Say goodbye to the traditional air purifier since you need to regulate your home’s air quality more intelligently.

And don’t forget that the best-in-class performance of this Blueair HealthProtect 7770i is certified by the Association of Home Appliance Manufacturers (AHAM), so you get the most complete air purifier for the money and the greatest personal fan power available.

Because of this, this is the only air purifier on our list to get an S- ranking.

Here are the pros/cons of the Blueair HealthProtect 7770i:

2) Blue Pure 411 Auto – The Best Air Purifier 2024 ($100)

The Blue Pure 411 was once the best budget air purifier in any list, thanks to its simplicity. Simply press the play button once, and the gadget will take care of the rest. Its 360° air inlet eliminates placement restrictions without sacrificing performance. So far, the air purifier is the most affordable air purifier available from this Swedish luxury brand.

Blueair surprised everyone when it released the Blue Pure 411 Auto, with the air purifier offering the greatest core Blue family capabilities, as well as a Smart Sensor, for the same price as the previous non-smart model.

The new Blue Pure 411 Auto will enhance the HEPASilent technology of the Blue family’s traditional air filter. Three levels of air filtration are now available in a single pack.

1. Pre-filter – It’s worth noting that the fabric pre-filter of the Blue Pure 411 Auto is outside the air purifier. As a result, this pre-filter is a huge benefit since you can quickly check its condition and remove the impurities instantly.
2. Particle Filter – Instead of using a True HEPA filter, the Blue Pure 411 Auto runs a polypropylene fiber filter to help capture 99.97% of all allergens like dust, dust mites, pet dander, pollen and fungi (HEPASilent technology).
3. Activated Carbon Filter – The air filter is integrated into the particle filter and is efficient against smoke, smells, gases, and volatile organic compounds (VOCs).

For a Blueair device, even the most affordable device is actually nothing like a budget device, as it is still loaded with premium hardware and features. Take, for example, the new HEPASilent technology, which provides the same level of performance as conventional True HEPA filters while being quieter and more energy efficient.

The new premium fabric colors are inspired by the natural landscapes of Scandinavia, and the Blue Pure 411 Auto is not only your best smart air purifier on a budget, but also the most gorgeous one.

Again, we must highlight that the Blue Pure 411 Auto has dual air sensors. It will detect dust and odors separately and adjust the fan speed accordingly to maintain clean indoor air. Indeed, the more costly Coway AP-1512HH is equipped with only one air sensor.

Ranks A-, the Blue Pure 411 Auto is the best air purifier you can find on budget around $100.

3) Levoit Core 300S – The Best Air Purifier 2024 ($150)

As nights follow days, does Levoit produce one great air purifier after the next. And, just like the original Core 300, the Levoit Core 300S takes budget air purifier refinement and quality to a whole new level and for most people it will be the ideal companion. It is also certified by Energy Star and CARB to be efficient and safe to use.

The Levoit Core 300S is the best affordable portable air purifier with a strong air cleaning mechanism, having won the Reddot Award and several other world-renowned design rewards.

1. Pre-filter – This nylon 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% down to 0.3 microns dust mites allergens, virus particles, pollen, bacteria particles. Can be customized:
   • Pet Allergy – For anyone with extreme allergies with pets. Levoit also makes a special version for this feature: the Levoit Core P350.
   • Toxin Absorber – For areas with high levels of smoke, VOCs, or chemicals.
   • Smoke Remover – For smoke-heavy environments.
3. Activated Carbon Filter – It is great at eliminating odors and smoke in your home.

There are several reasons to like the Levoit Core 300S. It features the greatest True HEPA filter we’ve encountered and is far less expensive than some of its competitors. As with the high-end Rabbit Air MinusA2, this original HEPA filter may be tailored to meet your specific demands. If you suffer from severe allergies or asthma, you should not overlook this air purifier. True HEPA filter removes 99.97 percent of dust, smoke, odor, mold spores, pet dander, and particles as tiny as 0.3 microns.

At its price point, the air purifier is only suitable for usage in small rooms. However, the fan power of this gadget is superior to that of most of its competitors, making it a clear winner. At a 140 cfm CADR rating, the Levoit Core 300S can handle most air purifying tasks easily.

The reason you pay more for this Levoit Core 300S is its smart features, which includes both Smart Sensor and Wi-Fi capability. The Levoit VeSync app is very much an evolution of the air purifier applications, and it helps you manage the Core 300S to the fullest. You can also connect to Amazon Alexa or Google Assistant to voice control the device, which is convenient when your hands are full.

If you want to up your air purifier game to $150, the Levoit Core 300S is the best air purifier 2024, which ranks A in our ranking system.

Here are the pros/cons of the Levoit Core 300S:

4) Winix AM90 – The Best Air Purifier 2024 ($200)

What would you expect when paying $50 more from the great Levoit Core 300S? You must want your air purifier to cover larger room, and yes, the Winix AM90 is the best air purifier you could buy.

For the Winix, this is a must-look brand when looking for an air purifier in your home. With over 15 years of expertise in the United States, the Korean-based firm is the perfect answer for any type of pet allergy, delivering cutting-edge technology at an astonishingly affordable price.

Being certified by the Energy Star, AHAM and CARB for its great performance, the Winix AM90 delivers the exclusive air filtration system made only by the South Korean company.

1. Pre-filter – The polluted air must pass through a built-in pre-filter. This pre-filter will help capture the large objects of contaminants, such as pet hair and even some kinds of pet dander and skin.
2. Activated Carbon Filter – The air filter can adsorb household odors from cooking, pets, and smoke and reduce VOCs.
3. True HEPA Filter – The True HEPA Filter that captures 99.97% of as small as 0.3 microns allergens, virus particles, pollen, mold and fungi particles.
4. Winix PlasmaWave – The exclusive Winix technology to safely destroy the pollutants. Can be switched on/off.

Winix AM90 is equipped with Winix’s exclusive PlasmaWave technology, which allows it to generate both positive and negative ions (in plasma state). Then it generates Hydroxyls, which are used to neutralize several types of airborne contaminants, including viruses, bacteria, germs, smells, and chemical fumes (VOCs). This method is capable of effectively eliminating even the tiniest biological particles, as tiny as 0.1 microns in diameter.

The combination of True HEPA filtration and PlasmaWave technology is what makes the Winix AM90 so effective against the majority of harmful pollutants. Additionally, unlike the ionization filter, the PlasmaWave will not aggravate asthma or respiratory problems. That is why PlasmaWave is regarded as the safest method for combating even the tiniest bacteria.

Combine these air filtration devices with a powerful fan to create an air purifier capable of covering 360 square feet without difficulty. The AHAM has confirmed the Winix AM90, and it performs comparably to the Coway AP-1512HH and Honeywell HPA300 in the same price range.

However, the Smart features are the reason to choose the Winix AM90 above other air purifiers. This air purifier may be controlled wirelessly via your smartphone or Alexa’s voice commands. Additionally, you will have a Smart Sensor that will alter the fan speed based on the needs of the area.

Ranks A, the Winix AM90 is only slightly behind the Coway AP-1512HHS in terms of annual filter replacement cost.

Here are the pros/cons of the Winix AM90:

5) Coway AP-1512HHS – The Best Air Purifier 2024 ($250)

Coway has been the market leader in South Korea for air purifiers for a long time, and this is one of the greatest air purifier firms in the world, having beaten Samsung in the domestic air purifier market alone. The Coway AP-1512HHS is the our new selection to replace the old Coway AP-1512HH because of its exceptional performance and value for money.

The Coway AP-1512HHS removes the ionizer feature, touting with its incredible 3-stage air filtration system.

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% down to 0.3 microns allergens, virus particles, pollen, mold and fungi particles.

The Coway AP-1512HHS (or Airmega AP1519)’s performance is of a very high standard, going head-to-head with any air purifier in the $300-$400 range, such as Oransi Max or Rabbit Air BioGS 2.0. It handled everything we threw at it while being reasonably priced, making it an excellent choice for anyone on a budget.

Another unique selling point is its outstanding Eco Mode, which automatically shuts down the fan when it detects no air pollution, which is ideal for energy conservation. As an Energy Star-certified air purifier, the Coway AP-1512HHS is a long-term investment that has low annual filter and energy expenses.

It features a Smart Sensor that automatically adjusts the airflow speed based on the current state of the air quality. This air purifier’s room coverage is remarkable at 360 square feet, based on the 4 air changes per hour rating. With this level of performance, it’s understandable why the Coway AP-1512HHS has received several certificates and honors, including the British Allergy Foundation Seal of Approval.

Our only criticism of the previous Coway AP-1512HH is that the top-mounted display light, which is too bright and cannot be shut off, has been removed in this Coway AP-1512HHS. As a result, the new air purifier is genuinely ideal.

Ranks A+, the Coway AP-1512HHS has better ranking than the Winix AM90 thanks to its better annual cost ranking.

Here are the pros/cons of the Coway AP-1512HHS:

6) Levoit Core 600S – The Best Air Purifier 2024 ($300)

However, if you can afford $50 more, you will get an air purifier with ever larger room coverage. We call the Levoit Core 600 as “flagship killer”, because it has very high performance for the price.

Levoit overthrows the Airthereal AGH550 with its own Levoit Core 600S, an air purifier that has everything you’ll ever need for your home: excellent air purifier specs at an affordable price, cutting-edge smart capabilities, and a simple, powerful all-in-one air filter. This could be the endgame for many air purifier purists, as verified by both the California Air Resources Board (CARB) and Energy Star.

Its air filtration system is an upgraded version of the old Levoit device – the Levoit LV-H134. Let’s take a look at the air filtration system of Levoit Core 600S.

1. Pre-filter – Levoit Core 600S’s mesh preliminary filter captures the most large objects such as dust, hair, lint, fibers, and pet fur at the first stage of its air filtration.
2. True HEPA Filter – Levoit Core 600S uses a H13 True HEPA Filter (its own HEPASmart technology) to reduce 99.97% of as small as 0.3 microns allergens, virus particles, pollen, and bacteria particles.
3. Activated Carbon Filter – The custom-formulated high-efficiency Activated Carbon filter (ARC formula) is exceptionally excellent at eliminating cooking odors and pet scents in households with several pets. Additionally, it prolongs the filter’s life by chemically decomposing molecules trapped within the Activated Carbon Filter, preventing oversaturation and second-hand pollution.

For roughly $249, you’ll receive a powerful CADR rating of nearly 400 cfm, which is capable of coping with medium to extra-large rooms. That’s not to mention the advanced AC motor featured in the Levoit Core 600S‘s core, which significantly reduces energy costs. It’s expected that this air purifier is Energy Star certified.

It also uses a laser sensor to provide customers with a more accurate and timely measurement of the air quality, since the report is sent in less than ten seconds. This smart sensor easily outperforms all other cheap air sensors and is on par with high-end air purifiers.

And what brings Levoit Core 600S to the top of our list of the finest air purifiers are its advanced smart functions. The air purifier can sense light and automatically adjust its Auto Mode to assist you in sleeping better. Plus, the Levoit Core 600S can be connected via the VeSync app, which provides additional relevant information and assists in controlling it more effectively. Further, it may be controlled via voice commands using Google Assistant or Amazon Alexa.

For most people, you can stop looking for more expensive devices, because this Levoit Core 600S ranks A+, which is the second-highest ranking in our ranking list.

Here are the pros/cons of the Levoit Core 600S:

10) LG PuriCare AS560DWR0 – The Best Air Purifier 2024 (>$800)

If you’re still reading, you’ve probably already narrowed your search to ultra-luxury high-end air purifiers. The LG PuriCare is the best premium air purifier you can get for your home. As an air purifier certified by the Asthma & Allergy Foundation of America (AAFA), the LG flagship is one of your top choices to combat allergies and asthma from air irritants.

It seems we don’t need to introduce anything about LG – a household appliances giant in South Korea. Its air purifier flagship is very powerful with a traditional 2-stage air cleaning system.

1. True HEPA filter – The main HEPA filter that captures 99.97% of allergens, virus particles, pollen, mold and fungi particles down to 0.3 microns.
2. Activated Carbon Filter – The deodorization filter catches odors, smoke and Volatile Organic Compounds (VOCs) like formaldehyde.

Due to LG’s newest SmartThinQ technology, the LG PuriCare AS560DWR0 can sync your air quality with your Google Assistant or Amazon Alexa for voice control. Additionally, you may download the LG app and make modifications directly from your smartphone.

With its clean booster, the air purifier is genuinely unique. This function enables LG PuriCare to rapidly pump air up to 24 feet. It allows you to tilt the fan up to 55 degrees and spin it up to 70 degrees in order to send clean air precisely where you need it. This also ensures the most uniform distribution possible.

The air purifier’s high CADR rating of 365 cfm enables it to disperse clean air uniformly around a space measuring 500 to 1000 square feet. What’s the best part? LG PuriCare AS560DWR0 operates at a noise level of 25 decibels (dB), which is softer than a whisper.

Because it’s Energy Star certified, you don’t have to worry about overspending on electricity when using this air purifier.

The LG PuriCare AS569DWR0 ranks A+, meaning it’s your best air purifier at more than $800.

Here are the pros/cons of the LG PuriCare AS560DWR0:

Review: LG PuriCare AS560DWR0 Review.

11) Blue Pure 311 Auto – A Great Air Purifier for Bedroom

From 11 to 15, we will list some of the most impressive air purifiers in our list, which can’t move into top 10 with their overall rankings. However, these air purifiers have something that we definitely love to mention.

The Blue Pure 311 Auto is a great air purifier for bedroom if you need more room coverage than the Blue Pure 411 Auto. That’s because it delivers a near-flagship Blue experience but does so for a fraction of the cost. Indeed, the Blue Pure 311 Auto is so cheap that it rings in for under half that of the flagship Blue Pure 121, and for that reason alone it demands checking out by any prospective air purifier buyer.

Every member of the Blue family utilizes the same fundamental air filtering mechanism. You just get a bigger air filter and a more powerful fan system.

1. Pre-filter – The high-end fabric pre-filter can capture most of the largest pollutants like dust and pet hair.
2. Particle Filter – Instead of using a True HEPA filter, Blue Pure 311 Auto runs a polypropylene fiber filter to help capture 99.97% of all allergens like dust, dust mites, pet dander, pollen and fungi (HEPASilent technology).
3. Activated Carbon Filter – The air filter is added inside the Particle filter and is effective against smoke, odors, gases and VOCs.

It really does deliver in terms of modern air purifier experience, too, with the new smart sensor that you won’t have in other members of the Blue family. That means that this air purifier delivers a high-end HEPASilent technology-level of power and energy efficiency, which combined with the core nature of simplicity as a Blue device. That makes using the Blue Pure 311 Auto an absolute joy.

Yes, the Blue Pure 311 Auto cuts a few corners when compared to the flagship Blueair devices, but its fan power is by far better than most air purifiers at the $200 range. Considering just how remarkably cheap the air purifier is, and that all its components deliver strong performance, it is really hard to overlook it.

Just like the Blue Pure 411 Auto, we have a new set of premium fabric pre-filter, inspired by the natural landscapes of Scandinavia. If you’re in the market for a new air purifier, we recommend checking it out first. You might be amazed at how much quality Blueair has packed into this gadget for such a low price.

However, the Blue Pure 311 Auto only ranks B+, but we love its simplicity, and we still get one for our public siesta room.

Here are the pros/cons of the Blue Pure 311 Auto:

12) TruSens Z-3500 – A Great Air Purifier for Killing Viruses

While the GermGuardian AC9600W is currently the best air purifier for virus, we love the concept and design of the TruSens Z-3500 a lot more (your mileage may vary). It also has better overall ranking than the GermGuardian flagship.

TruSens, a U.S. company known for producing only high-quality air purifiers, produces a wide range of decent to exceptional air purifiers that feature UV-C light filtration to make mold spores, viruses, and bacteria ineffective. Among many devices, the TruSens Z-3500 is the most powerful air purifier, with many certifications of the Energy Star, AHAM and CARB for high performance, energy efficiency and safety.

1. Pre-filter – A permanent, washable pre-filter screen captures large dust particles and pet hair, mostly to help extend the life of the True HEPA filter.
2. Activated Carbon Filter – Can remove certain gases and odors from the air, as well as many types of Volatile Organic Compounds (VOCs).
3. True HEPA filter – TruSens Z-3500 uses a True HEPA filter to capture 99.97% of any allergens down to 0.3 microns.
4. UV-C light filter – Using UV sterilization, the TruSens can kill 99.8% of hazardous germs and bacteria in the air. It also reduces the growth of odor-causing microbes on the surface of the filter.

If you are facing problems with the viruses, bacteria and mold spores – which are the biological contaminant particles, traditionally, we’d be pointing you towards an air purifier with a UV-C light filter. The UV-C light, which is harmless to us, can operate in conjunction with titanium dioxide to damage the core DNA of germs and viruses, thereby eliminating them.

TruSens Z-3500 is not just efficient because of the UV-C light; the device also has a high-quality True HEPA filter and an Activated Carbon filter. Its jaw-droppingly good performance is associated with a high CADR-rating fan power, as verified by the AHAM.

As one of the highest-ranking air purifiers in 2024, the TruSens Z-3500 features its unique Smart Sensor. The Sensor Pod can take accurate air quality measurements within 49 feet, then it will inform you quickly through the air quality monitor. Moreover, as the latest model in its family, the TruSens Z-3500 has its own smart app, so you can remotely control it or use voice commands like Google Assistant or Amazon Alexa.

The TruSens Z-3500 ranks A-, which is very good on our list.

Here are the pros/cons of the TruSens Z-3500:

13) Alen BreatheSmart 75i – A Great Air Purifier for Lifetime Warrranty

Though we don’t buy an Alen BreatheSmart 75i for our home and office, its Lifetime warranty is very impressive that we couldn’t forget to mention.

As the upgraded version of the previous flagship – the Alen BreatheSmart, the Alen BreatheSmart 75i is the best flagship of the Alen Corp, earning the Consumer Digest’s Best Buy. Finally, we have a True HEPA air purifier from this brand, which is backed up by the lifetime warranty policy.

Let’s take a look at the 3-stage air cleaning system to meet your needs in the Alen BreatheSmart 75i:

1. Pre-filter – A washable pre-filter to help capture the large objects of pollutants like dust, pet hair and pollen.
2. True HEPA Filter – There are 4 types of True HEPA filter for you to choose from:
   • Pure – The standard True HEPA filter of Alen BreatheSmart 75i, which is able to capture 99.97% of as small as 0.3 microns pollutant particles such as dust, dust mites and pollen.
   • Fresh – The next level HEPA filter will improve the first Pure, with the addition of Activated Carbon filter, to deal with household odors and chemicals. This air filter is necessary for people who are sensitive to VOCs.
   • Pet – Without the Activated Carbon filter, the Pet air filter uses Alen’s patented Molecular Conversion Powder to ensure heavy pet odors are destroyed at a molecular level.
   • Heavy Odor – Alen BreatheSmart 75i changed the Molecular Conversion Powder in the Pet air filter to make the new Heavy Odor filter, which can remove household odors from smelly kids/teenagers, kitchen garbage, and other everyday activities.
3. Ionizer – The ionizer is used to improve the efficiency of the Alen BreatheSmart 75i. Can be switched on/off.

The Alen BreatheSmart 75i is the first time the brand’s True HEPA air purifier was seen as a real rival to the Rabbit Air MinusA2. With 4 different types of True HEPA filter, Alen BreatheSmart 75i is ready to deal with any types of pollutant particles, while being safe with limited ozone emission from the ionizer.

It boasts more fan power than any of its predecessors, with the widest room coverage of 1300 square feet. However, the Alen BreatheSmart 75i is undoubtedly silent due to the WhisperMax technology. This air purifier also generates soothing pink noise – a frequency proven to help you sleep 25% better. Isn’t this an excellent air purifier for the bedroom?

The device is still an absolute looker with 15 panel color options including white, oak, brushed bronze and stainless, black, rosewood, natural maple and more to match your personal style.

Finally, this air purifier will have high-end features such as a Smart Sensor with an LED light indication. It adjusts the cleaning power of the BreatheSmart 75i to maintain the highest possible air quality while conserving energy and increasing filter life. As a result, the air purifier also earns an Energy Star certification.

The fact of the matter is, it doesn’t get much better than the predecessors anymore, because you can get the True HEPA filter for any Alen air purifier at the moment.

The Alen BreatheSmart 75i only ranks B+ in our ranking list, but we choose it because of its Lifetime Warranty.

Here are the pros/cons of the Alen BreatheSmart 75i:

14) Airdog X8 – A Great Air Purifier for Reducing Annual Filter Cost

An air purifier doesn’t need annual filter replacement, well, that’s a dream for everyone. It will avoid the hassle of installing new air filters, which are very costly. We can also help the environment by avoiding discarding waste filters. That’s exactly the basis of the Airdog X8.

In this high-range segment, only bulky machines which can cover a large area have a chance to compete in. Airdog is the new player in air purifier field, but its filterless air system truly works, and the Airdog X8 is its most high-end masterpiece.

Let’s take a look at its unique 4-stage air cleaning system.

1. Pre-filter – The polluted air must pass through a pre-filter screening, where it traps large particles of pollutants like hair and dander. It is washable and permanent.
2. Ionizer – The ionic field is created on the surface of the generator wires (or emitter wires) and is also the main filtration method of the Airdog X8. It can destroy even the 0.0146 microns ultra-fine particles, such as bacteria, germs and viruses. In addition, it is also effective in removing the pet dander, pollen, dust and other particles that are larger than 0.3 microns.
3. Collecting Plate – While not being a layer of protection, the collecting plate is necessary to collect the harmful particles inside. These heavy-duty but dishwasher-safe plates can easily be cleaned, saving you from expensive replacement filters.
4. Composite Catalyst – The last filter of this Airdog X8 is actually an Activated Carbon filter, which removes odors, smoke and chemicals. This is also where the Airdog X8 remove the ozone emission, to guarantee the cleanest air quality for your home.

Airdog X8 touts itself as the world’s first washable air purifier, but it’s not true. However, its advanced air filtration system excels far from the first model – the fundraising Airdog X5. Its performance has been upgraded, and it is among the best air purifiers you can get at the moment.

The ionizer is strong, and it doesn’t need annual filter replacement, so the investment in an Airdog X8 is nearly permanent. The allergens will be settled on the collecting plate, which is dishwasher-safe.

Airdog X8 delivers 470 cfm of clean air, and such performance is enough to handle any large room’s task. So far, this air purifier is recommended to clean rooms up to 1000 square feet.

One more thing to get an Airdog X8 is its smart features. Airdog X8 features a number of smart functions, including a Smart Sensor and Wi-Fi capability. The Smart Sensor is effective against both dust and gas particles, and it features an Auto Mode that automatically adjusts the fan’s speed based on the current air quality level.

Airdog X8 ranks A, which is only behind the LG PuriCare AS560DWR0 in top 10 by a little.

Here are the pros/cons of the Airdog X8:

15) IQAir GC MultiGas – A Great Air Purifier for Wildfire Smoke

In California, we are facing increasingly catastrophic wildfire seasons. That’s why the IQAir GC MultiGas is another impressive air purifier that we want to introduce to Breathe Quality’s readers.

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, and one active partner of the American Lung Association.

Let’s look at the product IQAir proudly claim to be the #1 Air purifier for smoke, odors and MCS – IQAir GC MultiGas. This air purifier features four stages of superior filtration as below:

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 of its HEPA filter, IQAir GC MultiGas implements HyperHEPA technology to increase the particulate loading capacity by 13%. As a result, the air filter will run great for one year.
