2) Sharp FP-A80UW – Runners-up in Killing Mold Spores in 2018

Sharp is a Japanese multinational corporation that designs and manufactures electronic products. Despite of its popularity among Asian regions, Sharp air purifier is not a impressive name to be heard in the U.S region. However, the quality of their products is undeniable. Today, in the list of best air purifiers for mold, mildew and virus, we will check a candidate from Sharp – Sharp FP-A80UW.

As the runners-up of this list, what can Sharp FP-A80UW can show off to our readers?

  • Additional Filters – Sharp has an unique technology named Plasmacluster ions. Unlike the normal ionizer, these Plasmacluster ions not only just attract contaminants to make a bigger form, but these ions can also extract the protein components of mold spores and viruses. Thus these ions can decompose the protein and suppress the mold spores and viruses in the air. Can be switched on/off.
  • True HEPA Filter – Combining with the wonderful Plasmacluster technology is a great True HEPA filter. This filtration process can trap 99.97% of airborne pollutants as small as 0.3 microns, including mold spores, mildew and other contaminant particles.
  • Activated Carbon Filter – A high quality Activated Carbon filter is also available to help put an end to the mold odor and chemicals.

best air purifiers for mold

The main difference of this Sharp FP-A80UW air purifier from others in this list of best air purifiers for mold in 2018 is certainly the lacks of UV-light air filtration. Instead, this air purifier is inherited the powerful Plasmacluster technology, which is exclusively in Sharp air purifiers. Sharp has perfected this technology to be as natural so it won’t trigger any types of asthma. Otherwise, this technology is one of the best to remove mold spores, mildew and viruses.

Also, Sharp FP-A80UW is truly powerful with an effective True HEPA filter. This well-built layer of filtration can last for up to 2 years without need of replacement, successfully reduce the cost of annual filter replacement. Without a doubt, this air purifier deserves a 9 on a scale of 0-10 for performance rating.

One more great advantage when buying Sharp FP-A80UW is the powerful fan. With a high CADR of 303 Dust/ 293 Smoke/ 360 Pollen (cfm), this air purifier have no problem at cleaning a large room of up to 454 sq ft. As strong as the fan is, the Library Quiet technology from Sharp is useful to keep this air purifier quiet in real-world use.

Mentioning the additional features, we will have a stable Smart Sensor and other add-ons like Timer or LED filter replacement indicator. If there could be a reason to hesitate buying this air purifier, it must be the high price tag for a mid-range product. Anyway, we believe a good investment will give better benefits, so you need to check the price of Sharp FP-A80UW right now.

Here is the pros/cons of Sharp FP-A80UW

PROS


  • Best performance rating to kill mold spores
  • Innovative and great air filtration process
  • Has Smart features like Smart Sensor
  • Library Quiet technology works perfectly
  • Large room coverage: 454 sq ft

CONS

3) Oransi Finn – Secures the Third place in Best Air Purifiers for Mold in 2018

Like Biota Bot, Oransi is a great US air purifier brand that is rising in the last few years. Their Oransi Finn is a well-built UV air purifier which targets directly at mold and mildew allergies and asthma. This air purifier easily secures the Third place in our 2018 list because of several reasons as below:

  • Activated Carbon Filter – The pre-filter of this air purifier is attached with an Activated Carbon filter. As a result, this filter will both capture the large objects of contaminants as well as the annoying mold odors and chemicals.
  • True HEPA Filter – Oransi calls their HEPA filter V-HEPA, which is an effective filtration to capture mold spores and tiny bacteria.
  • UV-C Light – A prominent UV-C lamp to destroy the structure of any viruses and mold spores.

best air purifiers for mold

With an effective 3-stage air filtration, Oransi Finn is a wise selection to remove mold spores, mildew and viruses in your house. The combination of both True HEPA filter and UV lamp is certainly worth your money.

Just like Sharp FP-A80UW, your Oransi Finn has a high base cost of filter. But thanks to the innovative technology to expand the life time of Oransi V-HEPA filter, you will not need to replace your filter in next 2 years. Also, if you follow our above deal, you will have a free 2 pre-filters to replace the current one anytime. Good deal, huh?

For the fan power, the manual of Oransi Finn said that it can cover a room of up to 400 sq ft. However, the Oransi Finn brings a weaker fan power than the top two of this list. It can only run at an average CADR of 140 cfm. Another minus to this air purifier is the loud noise level at both low and high settings.

As another high-end machine, we can assure that you will have a good Smart Sensor in it, along with other functions like Timer or LED filter replacement indicator.

Here is the pros/cons of Oransi Finn

PROS


  • Powerful performance rating to kill mold spores
  • Strong air filtration process
  • Has Smart features like Smart Sensor
  • Well-built for the price
  • Large room coverage: 400 sq ft
  • 10-year warranty
CONS


  • Quite noisy
  • Low CADR for the room coverage

4) GermGuardian CDAP5500BCA – Best Deal for limited time

It is safe to say at the moment, GermGuardian is the best brand to find a budget air purifier with powerful air filtration process. The signature of all GermGuardian air purifiers is the combination of both True HEPA filter and UV-C light filter. Up until now, the latest product this brand brings to you is, also one of our 2018 list of best air purifiers for mold, GermGuardian CDAP5500BCA.

Using a powerful 4-in-1 Air Cleaning System, do you have belief in this device?

  • Additional Filters – GermGuardian CDAP5500BCA is using a pre-filter to capture large objects of contaminants. Just like Biota Bot MM208 pre-filter, you can wash or vacuum this pre-filter and keep it permanent to use.
  • True HEPA Filter – A certified True HEPA filter to capture 99.97% of 0.3 microns and larger particles like mold spores, dust and pollen.
  • Activated Carbon Filter – Reduces odors created from mold and mildew.
  • UV-C Light – UV-C Power helps kill airborne bacteria, viruses and mold spores. GermGuardian UV-C light must pass a strict test to be used in common air purifiers of this brand.

best air purifiers for mold

It is unbelievable a 4-stage air filtration similar to Oransi Finn costs you only under $200. GermGuardian CDAP5500BCA continues the tradition of this brand to utilize both best power to destroy mold spores and even viruses.

One more thing will give you a “wow” reaction is within a price tag under $200, this air purifier comes up with both Wifi-enable and Alexa-enable features. Using their GT app (available in both iOS and Android), you can easily control this air purifier with your smartphone.

If you still think GernGuardian will sacrifice any additional features for this wifi capability, you are unluckily (luckily) wrong. GermGuardian CDAP5500BCA still features a Smart Sensor named SmartAQM and other common functions like any air purifiers in this list.

But this air purifier is not perfect. It has a weak fan power with only 193 sq ft room coverage. If you have a larger room, chance is you need to purchase one more GermGuardian CDAP5500BCA to clean the air. Good thing is, the CADR of this air purifier is sufficient to cover this 193 sq ft, with 114 Dust/ 108 Smoke/ 127 Pollen.

Here is the pros/cons of GermGuardian CDAP5500BCA

PROS


  • Great performance rating to kill mold spores
  • Powerful air filtration process
  • Smart Features like Sensor and Wifi Capability
  • Best Deal for low-range segment
  • 5-year warranty
CONS


  • Quite noisy at highest setting
  • Alexa voice command seems bad
  • Small room coverage: only 193 sq ft

5) InvisiClean Aura – Best Performance rating for Mold in Low-range

Not only Biota Bot MM208 is the only air purifier to cover all the air filter types, InvisiClean is also one can do this. This US brand becomes more popular with their signature air purifier – the InvisiClean Aura. Let’s see if the 4-level of Air Cleaning is enough for you to purchase this product or not.

  • Additional Filters – Just like Biota Bot MM208, InvisiClean Aura adds one level of air filtration with its ionizer. This features can be shut off.
  • True HEPA Filter – A made-in-South Korean True HEPA filter to capture 99.97% of all airborne particles, especially including mold spores.
  • Activated Carbon Filter – Reduces odors created from mold and mildew with ease. This filter can also capture large objects of contaminants such as dust and hair.
  • UV-C Light – A decent UV-C Light to get rid of mold spores and viruses in the air.

best air purifiers for mold

Like we said earlier, you will have a combination of all air filter types in InvisiClean Aura. For an air purifier to combat mold, mildew and viruses, you could be rest assured that this air purifier is one of the best you could get.

The fan setting of InvisiClean Aura also impresses us. With a room coverage of 319 sq ft, this air purifier has a high CADR of 170 cfm. Notice that this air purifier is a low-range device of around $100 and it still has better fan than an Oransi Finn.

The money feature of this air purifier is its low energy consumption. We never expect an air purifying device could go as low as 3W, and the highest setting of this air purifier only consumes 47W. Using an InvisiClean Aura, you will have no worry of a surprise electric bill.

As a trade off, you will not find the Smart Sensor in this air purifier. Instead, you can use the Timer and select the desired duration you want your air purifier to run.

Here is the pros/cons of InvisiClean Aura

PROS


  • Decent performance rating to kill mold spores at low-range
  • Great air filtration process
  • Good fan power with a high CADR
  • Large room coverage: 319 sq ft
  • 3-year warranty
CONS


  • Quite noisy
  • No Smart Features like Smart Sensor

6) PureZone Elite – Another All-round for Mold in Low-range

It seems being an all-round air purifier (air purifier with all air filter types) is a good trend to be a best air purifier for mold, mildew and viruses. In the slot number 6 is the PureZone Elite – the flagship device of Pure Enrichment, a California brand.

You will expect exactly these features when buying an all-round air purifier.

  • Additional Filters – Another air purifier makes use of the ionizer to increase the efficiency of capturing airborne particles. This features can be shut off.
  • True HEPA Filter – This True HEPA filter is able to capture 99.97% of all airborne particles, especially including mold spores and other pollutants.
  • Activated Carbon Filter – Reduces odors created from mold and mildew to help you breathe easier.
  • UV-C Light – A good UV-C Light is also included in a photo catalyst filter to be used.

best air purifiers for mold

In the same low-range market, there are many potential candidates to be selected in Breathe Quality. As one of these potential, PureZone Elite must have a different air filtration process to win over other air purifiers. Using a same air cleaning system like InvisiClean Aura, this air purifier is a good all-round within low-range segment. No matter how many mold spores in your house, PureZone Elite could easily eliminate all of them.

By comparison, PureZone Elite will have a Smart Sensor while with InvisiClean Aura, you will need to do everything manually. So lives with PureZone Elite certainly are more comfortable. Also, we prefer the control panel of PureZone Elite. It is simple, clear and intuitive.

But the main difference is (sadly) PureZone Elite will have a weaker fan power. You will have only a decent CADR of 120 cfm to cover a small area of 190 sq ft. However, with nearly a same fan power with GermGuardian CDAP5500BCA, the fact that this air purifier is $50 cheaper than the Wifi-enabled latter will still make you think it twice before purchasing anything.

Here is the pros/cons of PureZone Elite

PROS


  • Decent performance rating to kill mold spores at low-range
  • Good all-round air filtration process
  • Smart features like Smart Sensor
  • 5-year warranty
CONS


  • High noise level at highest setting
  • Small room coverage: only 190 sq ft

7) Bionaire – Good use, no filter replacement cost

In fact, a war with mold and mildew is a long run. If you know that the actual filter replacement cost is sometimes even higher than the air purifier itself, will you give up buying them and just let your health go worse?

So, let’s check Bionaire – another all-round air purifier in this list of best air purifiers for mold. That means this Canadian brand air purifier will have a good air filtration process as below.

  • Additional Filters – One again, you will have an ionizer to improve the performance of the air purifier of capturing airborne particles. This features can be switched on/off.
  • Permanent HEPA Filter – You will not have a True HEPA filter if you are using this air purifier. However, Bionaire is claimed to remove up to 99% of dust, dust mites, pet dander and of course, mold spores as small as 0.3 microns. Also, this filter has granular activated carbon to help remove smoke and mold odors.
  • UV-C Light – A decent UV technology to reduce germs, viruses, bacteria, mold and fungi.

best air purifiers for mold

Well, why an air purifier without True HEPA filter can secure a place in our Best Air Purifiers for Mold list? As we stated earlier, using a permanent HEPA filter is a great way to delete the annual replacement filter. Moreover, as a permanent HEPA filter created by a well-known brand like Bionaire, we will believe this filter still provides a decent performance. One more thing, to increase the efficiency of Bionaire, you need to vacuum the HEPA filter once every 3 months.

Fun fact: Bionaire is a Canadian multinational with stores in more than 20 countries.

Even without a True HEPA filter, the all-round air filtration process (with ionizer and UV technology) is sufficient to kill even the tiniest mold spores. We guarantee for our readers that for a $100 air purifier, Bionaire will not lose to anything in terms of mold killing capability.

The fan power of Bionaire is even better than many air purifiers in this list, with a good CADR of 153 Dust/ 152 Smoke/ 174 Pollen. This air purifier is enough to clean a medium room of up to 236 sq ft.

However, we should not expect much from an air purifier under $100 budget with lots of additional features. Bionaire doesn’t have any kinds of Smart Sensor like this feature is too luxury for it. Everything must be done manually.

Here is the pros/cons of Bionaire

PROS


  • Decent performance rating to kill mold spores at low-range
  • All-round air filtration process
  • No filter replacement cost
  • Good CADR for a medium room coverage: 236 sq ft
  • 3-year warranty
CONS


  • Quite noisy
  • No Smart features like Smart Sensor
  • Inferior power due to not have True HEPA filter

8) SilverOnyx – Best bang for the buck

We are having too many tower air purifiers as best one for mold, mildew and viruses, so it’s time we check a portable air purifier with enough power to help us breathe easier. From a small brand comes from Utah, SilverOnyx – the only air purifier product from this brand, is the proud child to forge the popularity of them.

This air purifier will represent a 5-stage air filtration process just like Biota Bot MM208, with nearly half the price.

  • Additional Filters – You will have a mesh pre-filter and a negative ionizer in SliverOnyx just like Biota Bot MM208. Both these features is capable of removing large particles and airborne allergens. The ionizer can be shut off.
  • True HEPA Filter – A True HEPA H13 filter captures 99.97% of dust and allergens up to 0.3 microns in size and is a perfect filter for mold spores.
  • Activated Carbon Filter – Neutralizes household odors and mold odors.
  • UV-C Light – Included in a photo catalyst filter, this UV LED light can destroy contaminants like mold and germs.

best air purifiers for mold

Just looking at this air filtration process above, many people will ask us why SilverOnyx is not the winner but the Biota Bot, right? Despite of having a good air filtration process and yet one of the best air purifiers for mold at this moment, SilverOnyx’s filters are not as good as the top three. The ionizer only releases 3 million ions/cm³, while the top ones’ ionizer can produce up to 10 million. Also, this air purifier’s True HEPA filter is great, but only last for up to 6 months. Calculating the air filter replacement is really easy, and you will realize which one to choose.

Nevertheless, the performance rating of SilverOnyx is still one of the top 10 air purifiers for mold and mildew.

Another good advantage of this air purifier is the low noise level. Being a portable air purifier, this advantage will make this one a good candidate to join in the list of best air purifiers for bedroom. Most importantly, this air purifier is a smart device, and you will benefit from its Smart Sensor, to automatically adjust the air flow to ensure the highest quality air.

The only one downside is, with a extra large room coverage of 500 sq ft, this air purifier just has a negligible CADR of 140 cfm. It will take more time for SilverOnyx to complete the air cleaning task in your room of 500 sq ft for sure.

Here is the pros/cons of SilverOnyx

PROS


  • Amazing performance rating to kill mold spores
  • Powerful air filtration process
  • Smart features like Smart Sensor
  • Has quiet operation
  • Small size to be put anywhere
CONS


  • Low CADR for a large room coverage: 500 sq ft
  • 1-year warranty

9) Home Image HI-9020 – The lowest cost all-round air purifier

What do you usually expect from an all-round air purifier with all air filter types? The performance rating? Yes, combining all air filter types is the best way to effectively use all the air filters’ advantages to clean air. Being expensive? Again, yes, you should think that an air purifier with all 4 air filter types will cost you much.

Actually, you still can have an all-round air purifier with much under $100. And here you are the Home Image HI-9020 – the lowest cost air purifier with all 4 types of air filter.

  • Additional Filters – With a built-in ionizer, this air purifier has enough power to capture the tiniest particles of pollutants, like mold spores. The ionizer can be shut off.
  • True HEPA Filter – It is surprise to have an under $100 air purifier with True HEPA filter, but now you have it, enjoy its power.
  • Activated Carbon Filter – This filter is also the pre-filter, can both capture the large objects of pollutants as well as the odor-causing elements like mold odors.
  • UV-C Light – Just like any other best air purifiers for mold, Home Image HI-9020 has a potential UV-light filter to help kill on contact the bacteria and mold spores.

best air purifiers for mold

We don’t have much to tell of the performance rating of Home Image HI-9020. These air filters from this air purifier works great, but with a low fan power (only 120 CADR), it’s still a difficult task for Home Image HI-9020 to cover everything. So before purchasing this air purifier, make sure your room is not larger than 200 sq ft.

As one of the best air purifiers for mold, all of the filter components in this Home Image HI-9020 have decent power. You will have a certified True HEPA filter, which is not usually being seen in an under $100 air purifier. That is awesome.

Like any other air purifiers in low-range segment, we hope that you don’t expect any luxury things like a Smart Sensor. However, only for this Home Image HI-9020 in this list, you can expect of a handy remote control within the box. It is necessary since the buttons of this air purifier are quite hard to press on.

Here is the pros/cons of Home Image HI-9020

PROS


  • Decent performance rating to kill mold spores
  • Great all-round air filtration process under $100
  • Handy remote control
CONS


  • No Smart features like Smart Sensor
  • Small room coverage: 200 sq ft
  • Only has 1-year warranty

One again, we have a candidate of GermGuardian brand. This one is also the cheapest  air purifier on this list of best air purifiers for mold with a lovely price tag of under $50. With only a quarter the price of the latest GermGuardian CDAP5500BCA, will this GermGuardian AC4100 help you live healthier without mold or not?

  • Activated Carbon Filter – This filter is included in the pre-filter, can both capture the large objects of pollutants and the mold odors.

best air purifiers for bedroom

After testing hundreds of air purifiers, we believe GermGuardian AC4100 is the best air purifier you could get with no more than $50. Though this air purifier can’t have a chance to compete with better budget range air purifiers, it still has a good performance with its 3-stage air filtration system. Actually, GermGuardian AC4100’s performance rating is on par with a $100 PureZone 3-in-1 Air Purifier.

One again, we don’t expect much from a $50 air purifier. So yes, no Smart sensor. No any smart features, either.

Here is the pros/cons of GermGuardian AC4100

PROS


  • Overall great performance rating for the price
  • Low-range cost under $100
  • Very light-weight
  • 3-year warranty
CONS


  • Quite noisy at highest setting
  • Bad smell
  • No True HEPA Filter

What are mold and mildew? In short, mildew is just one type of mold. And molds are fungi which not only cause damage to the surfaces they are growing on, but also release tons of spores.

Are molds harmful for your health? According to Centers for Disease Control and Prevention (CDC), exposure to damp and moldy environments may cause a variety of health effects, or none at all. However, just because you don’t have an allergic reaction to mold doesn’t mean you are immune to it. In fact, being exposed to mold over a long period of time can develop a strong allergy to anyone.

“In 2004 the Institute of Medicine (IOM) found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people; with asthma symptoms in people with asthma; and with hypersensitivity pneumonitis in individuals susceptible to that immune-mediated condition. The IOM also found limited or suggestive evidence linking indoor mold exposure and respiratory illness in otherwise healthy children.” (Source: CDC gov website).
