How Do We Measure?

Pollen CADR Regardless if the allergens are mold, pollen or mildew, the higher pollen CADR scores, the better it is. Measured in CFM (cubic feet per minute) on the amount of clean air that flows out of the air purifier. We pick Pollen CADR as a key point because it is an industry standard measurement by AHAM. Not all brand participate in the CADR test so HEPA filter is perhaps an even higher measuring factor.
HEPA filter Pollen, mold, and mildew are all microscopic allergens that are hard to be seen through our naked eyes. Only a HEPA filter would have the capacity to get rid of these microbe irritants. Not just any HEPA filter, a genuine True HEPA filter is precisely what we are looking for. To be part of the list, there must be a HEPA filter capable of removing microscopic allergens. Bonus points will be given to the HEPA air purifier that plays well with other filtration.
Room size/ Coverage Never underestimate the speed of mold and pollen infestation. Mold can spread around the house within 24 – 48 hours and slowly colonizes your home space one inch per day. Pollen is no slouch either that spread into our breathing space rapidly as it’s mostly airborne. An air purifier with strong airflow can easily cover an entire room from allergens intrusion. The wider the purifying coverage, the bigger room size it can support. But that cannot be the sole factor in determining the best mold air purifier. We also judge the air purifier based on its size, category, airflow speed and the cost of ownership.

Any of the Blueair air purifiers would fit into our best air purifier for mold spores list. We pick Blueair 605 because it is the most powerful in its Classic lineup. At 20 x 26 x 13 inches in dimension, this is not the air purifier to go with if you have limited spaces in a room. Adding the 35 pounds premium galvanized steel body, moving around Blueair 605 can be tricky despite the included caster wheels. Build quality is great and the fitting is tight. The extensive 5 years warranty is the perfect icing on the cake. Mold, spores, and other allergens trapped inside will have no chance of sneaking out.

Moving to the controls, Blueair 605 simple operation heavily relies on the LED display. You can cycle between the 3 fan speeds, reset the filter replacement indicator after changing the filters, and turn on Wi-Fi support. Blueair 605 supports remote access via the Blueair Friend app available for download in iOS and Google Play. It comes with advanced features such as brightness intensity, night mode, child lock, timer scheduling, and real-time air quality data with saved logs. Everything can be done at the comfort of your couch.

Looking inside Blueair 605 air purifier specification:

  • CADR - 640 cfm
  • Room Coverage - 775 sq. ft.
  • Fan Speed - 3
  • Air Filtration - HEPASilent Technology, Particle Filter, SmokeStop Filter
  • Warranty - 5 years

Blueair Classic 605 airflow delivery rate is from 150 cfm all the way up to 650 cfm at max speed. Even running at the lowest speed, airflow is plentiful and consistent. With up to 5 air changes an hour, it can cover a high 775 square footage of enclosed space. Ideal for large room sizes like living hall, dining room, lounge, basement, bedroom, or kitchen. CADR is highly impressive at 500 cfm for dust, 640 cfm for pollen, and 500 cfm for smoke. If you need to quickly remove mold, mildew, pollen, and other allergens in the air, Blueair 605 will not disappoint you.

HEPASilent Technology is the ultimate combination of electrostatic and mechanical filtration. The filters are ultrasonically bonded with natural antibacterial polypropylene fibers to prevent mold growth. It begins with the encapsulated particle-charging chamber electrostatically charging incoming pollutants to be more adhere to the particle filter. The sticky pollutants will be more sticky to the particles filter that boosts a 99.97% efficiency as small as 0.1 microns in size. The SmokeStop Carbon filter will absorb gas particles and ozone via chemical adsorption resulting a cleaner, fresher air.

Being a heavy-duty unit, Blueair 605 noise output is on the higher side between 32 dB(A) to 62 dB(A). You can still use it in the bedroom as long as you keep the fan speed low. The power consumption is acceptable hovering around 15 watts to 100 watts depending on the fan speed. Blueair 605 is Energy Star certified after all.

A powerful mold removal air purifier that will cost you an arm and a leg. Blueair 605 does have its fair share of downsides. It is gigantic and heavy compared to most of the air purifiers for mold. Despite the premium price you're paying, there's no air quality sensor and auto mode by default. The high annual filter replacement cost is also a recurring theme that you need to be aware of. So depending on how much air purifying is needed and how serious is your mold allergies, you could opt for the smaller Blueair 480i that reap the same benefits but at a much lower price.

In short: One of the best mold-removing air purifiers that can trap even the smallest microorganisms. However, the HEPASilent technology can be expensive to own and maintain thus it is not for everyone.

Do not be fool by Rabbit MinusA2 SPA-780A so-called “average” pollen CADR output. This is the ultimate 6-stage mold eliminator you can get your hands to. It has excellent purifying coverage (815 sq. ft. to be exact) that is ideal for any bedroom size.

Looking inside Rabbit MinusA2 air purifier specification:

  • CADR - 200 cfm
  • Room Coverage - 815 sq. ft.
  • Fan Speed - 5
  • Air Filtration - Pre-filter, HEPA Filter, Activated Carbon Filter, Negative Ion Generator, Medium Filter, Customized Filter
  • Warranty - 5 years

As the name suggested, this is the higher variant SPA-780A that cleans airborne mold in a room of up to 815 square footage at 2 air changes per hour. For a hypersensitive or asthmatic person that needs a persistent airflow, you can increase to 4 air changes per hour but the room size coverage will drop to 408 square footage. Rabbit Air MinusA2 airflow delivery rate is between 58 cubic feet per minute (cfm) to 218 cfm. Not the greatest but sufficient for a wall-mountable unit. CADR tally with the airflow output with dust at 193 cfm, pollen at 200 cfm, and smoke at 180 cfm.

No mold, mildew, and other biological pollutants will be able to bypass Rabbit Air 6-stage filtration. First, large irritants like dust, hair, pet dander, dust mite, and pollen will be captured either by the pre-filter or medium filter. For particulates that manage to bypass both the pre-filter and medium filter, you have the 99.97% efficiency HEPA filter standing by to trap particulates as small as 0.3 microns. For an even more in-depth removal, you can add 1 of the 4 customizable filters from Germ Defense Filter, Pet Allergy Filter, Toxin Absorber Filter, and Odor Remover Filter. Any smoke and musty odors that have not been deal with will be absorbed by the Activated Carbon filter. Last but certainly not least, an optional Negative Ion Generator will assist in pulling contaminants down for the multi-layered filter to capture.

In spite of MinusA2 and compactness and nifty purification, there are a few notable drawbacks. First, the CADR and airflow delivery rate is under par compared with its purifying range. Regardless of which variant you go for, you will have to pay top dollar for this air purifier. All the addons like customizable front panels and extra filters are extra costs to incur. Finally, the total weight is rather hefty, but it will not be a problem as long as you mount it to a wall. After all, that is the whole purpose of getting a Rabbit Air MinusA2.

In short: The only premium wall-mounted air purifier here that can deal with airborne mold and mildew allergens. For an even better filtration against microbes, consider one of the 4 customizable filters upgrade.

Many sites did not include IQAir HealthPro Plus in their "Best air purifier for mold list". Why? Because it is not an affiliate selling model worthy (psst is expensive). Not us as the airflow performance and filtration alone justified the inclusion. Top it off with a leading 6-speed mode and super wide coverage, you can never go wrong with HealthPro Plus.

Looking inside IQAir HealthPro Plus air purifier specification:

  • Pollen CADR - N/A
  • Room Coverage - 1098 sq. ft.
  • Fan Speed - 6
  • Air Filtration - PreMax Filter F8, HyperHEPA Filter H12/13, V5-Cell Gas & Odor Filter MG
  • Warranty - 3-10 years

There are two things IQAir does better than the rest: air cleaning and filtration. IQAir HealthPro Plus has 6 adjustable fan speeds that deliver from 41 cfm to a high 300 cfm of airflow delivery rate guaranteed. Following the impressive airflow performance is the wide 1098 square footage coverage. Highly suited for large room sizes with moldy problems due to poor ventilation and no sunlight like two car garage, basement storage, lounge, and laundry room. IQAir HealthPro Plus can even cover an entire home or condo when you leave all doors open with no obstruction.

The core of IQAir HealthPro Plus lies with its filtration. When airborne pollutants are drawn inside the 360 air inlet, the PreMax Filter F8 will block initial particulates from passing through and end up clogging the HEPA filter. Next, the remarkable HyperHEPA filter will trap microscopic allergens as small as 0.003 microns including bacteria and viruses. The V5-Cell Granular activated Carbon filter with Pelletized chemisorption filter removes even the toughest chemical fumes, ozone, and odors that are detrimental to our health. You will definitely feel improvement in the air quality simply by leaving IQAir on for a couple of hours.

There is no doubt on IQAir caliber in dealing with mold and other fungi. However, the close to 1000 pricing is the main reason many people will not opt for this model. Besides the hefty cost, the filter's sustainability is another setback as you will have to fork 100+ dollars year in, year out. The tall and bulky body is also very hard to maneuver despite the added caster wheels. Lastly, there is no autonomous mode or air quality indicator built-in, you will have to rely on the schedule for better energy management.

In short: The best mold removal machine when money is no biggie. If you have the budget and can sustain its filter replacement cost, go right ahead.

Winix HR1000 is another popular air purifier for mold that breaches the premium line but at the lower end. Let's put it this way, it cost close to double of Winix 5500-2 but only half of Airmega 300. Regardless of the price, this is a very good air purifier for all-purpose.

Looking inside Winix 5500-2 air purifier specification:

  • CADR - 246 cfm
  • Room Coverage - 360 sq. ft.
  • Fan Speed - 4
  • Air Filtration - Pre-filter, True HEPA filter, AOC Filter, PlasmaWave Technology
  • Warranty - 2 years

Despite being one of the more affordable mold air purifiers here, Winix 5500-2 packs quite a punch. the 4 adjustable fan speeds output a minimum 53 cfm to a modest 226 cfm airflow delivery rate. As for air cleaning coverage, it is recommended for room size up to 350 square footage at 2 air changes per hour. Suitable for small bedroom, kitchen, dining area, playroom, basement, and one car garage. As for CADR, Winix 5500-2 air purifier is rated at 243 cfm for dust, 246 cfm for pollen, and 232 cfm for smoke. Anything above 200 will be more than sufficient in dealing with home pollutants and curbing mold allergies symptoms.

Winix 5500-2 uses the familiar 4-stage PlasmaWave HEPA filtration that is effective in stopping mold and mildew growth. The permanent pre-filter traps dust, lint, hair, and other large contaminants. At the same time, it will reduce the dependence of the HEPA filter. The True HEPA filter capture 99.97% of particulates small as 0.3 microns. For smoke particles and toxic gases, you have the advanced granular carbon filter that absorbs cooking smells, VOCs, and clammy stale air. Lastly, PlasmaWave Technology generates natural water vapor and oxygen ion bonded Hydroxyls to eradicate microorganisms that are hard to break down. It is an absolutely safe and proven technology that does not produce harmful byproducts.

There are a lot of things to like about Winix 5500-2, the rather expensive HEPA + carbon filter replacement cost is not one of them. Expect to pay an average of 80 dollars annually with 24 hours of daily operation. The VOC sensors will occasionally doze off in detecting air quality changes, but the delay is momentarily so don't worry too much about it. It will not hinder Auto mode from functioning properly.

In short: A dependable yet inexpensive 4-stage filtration air purifier that has plenty to offer. Adding Winix's awesome PlasmaWave technology, no mold and mildew will be able to get away from its sight.

Most Winix air purifiers would fit well in our best air purifier for mold/ pollen list. We pick Winix NK105 out of the bunch as it is the only tower air purifier here. It’s considerably cheaper compared with the above air purifiers and is ideal for medium room size.

Looking inside Alen BreatheSmart air purifier specification:

  • CADR - 300 cfm
  • Room Coverage - 1100 sq. ft.
  • Fan Speed - 4
  • Air Filtration - Pre-filter, HEPA-Pure filter (upgradable), Ionizer
  • Warranty - Lifetime Limited Warranty

The OG model. Alen BreatheSmart air purifier 4 fan speeds output a strong 150 cfm to a maximum 286 cfm airflow. It can swiftly remove tiny particulates and pathogens in an 1100 square footage space under 1-2 hours. For those with asthma or severe allergies to mold, you can increase the air changes by 4 or clean air every 15 minutes. Best used in large spaces like a living room, dining area, kitchen, garage or basement with bedroom. Alen BreatheSmart CADR is averaging at 300 cfm for dust, pollen, and smoke with the default filter. The figures will not go too far off even if you opt for the upgraded filter set.

A superb mold removal machine with a little bit of quirk. By default, Alen BreatheSmart air purifier uses the standard HEPA-Pure bundled filter set. It comes with a washable pre-filter that traps large particles and prolongs the HEPA filter usage life. The highly dependable True-HEPA filter will capture tiny particles and pathogens that cannot be seen by our naked eyes. There is also a built-in ionizer that diffuses negative ions to charge positive ions contaminants in the air. The now heavier particles would fall allowing the HEPA filter to capture. Notice there is no smoke filtration here. For that, you will need to upgrade to the HEPA-Silver filter that specialized in capturing germs and smelly mold. A must-have in our book.

What's not so good about Alen BreatheSmart is the default HEPA-pure filter. It is the basic version that lacks odor filtration to deal with musty smells. You will need to top up for a better set which adds to the annual filter cost. Other than that, minor complaints like the loud noise, bright indicator, and dozy sensor are livable. Regardless of where you intend to use Alen BreatheSmart, it will have no impact on the air purifier's effectiveness against mold.

In short: Alen BreatheSmart strikes a balance between price, performance, and overall dimension. With the right set of filters, you can enjoy the best of both worlds for a lifetime.

Need something a little bit more affordable in dealing with mold? Again and again, Honeywell HPA300 allergen remover is your answer. It might not have an outstanding exterior or jam-packed features, the remarkable performance will make up for all.

Looking inside Honeywell HPA300 air purifier specification:

  • CADR - 300 cfm
  • Room Coverage - 465 sq. ft.
  • Fan Speed - 4
  • Air Filtration - Carbon Pre-filter, True HEPA filter
  • Warranty - 5 years

The dust CADR is at 320 cfm, and both pollen and smoke CADR is at 300 cfm. If you need to quickly remove mold, mildew, and other fungi in your home, Honeywell HPA300 air purifier will do just that.

Honeywell HPA300 uses a decade-old 3-stage filtration that is proven time and time again. The drawn-in particulates like dust, smoke, and odor will be removed by a carbon pre-filter and bar from passing through. Will most large contaminants filtered, the True HEPA filter will trap microscopic particles like pet dander, dust mite, mold, mildew, and pollen before releasing the clean air back out. The entire purification process will repeat itself until the air purifier is turned off.

Honeywell HPA300's inexpensive price tag is justified by the omission of few convenient features. There is no Auto mode, Sleep mode, AQ indicator, or remote control in the package. All you get is a timer that comes only with 3 pre-set settings. Another drawback is the high HEPA and carbon filter replacement cost especially for those that leave it on 24x7. You could save some money by purchasing the bundled pack or opt for third-party filters (not recommended). If the filter cost is too much of a burden, consider the smaller HPA200 or HPA100 variant.

In short: A great mold air purifier that is slightly dated on features. If you don't mind the manual control and lack of night mode, Honeywell HPA300 will do just fine.

Rather than pushing Airmega 300, let's go with the higher spec model. There are lots of things to like about Airmega 400 as a mold air purifier that we could go on all day. You only need to know that it is a proven, reliable, and effective pollen/ mold killing machine.

Looking inside Airmega 400 air purifier specification:

  • CADR - 350 cfm
  • Room Coverage - 1560 sq. ft.
  • Fan Speed - 3
  • Air Filtration - Pre-filter, Green True HEPA filter, Activated carbon filter
  • Warranty - 5 years

Coway Airmega 400 outputs an outstanding 350 cfm CADR for dust, pollen, and smoke.

Airmega 400 air purifier relies purely on a 4-stage mechanical filtration to clean the air. It is 100% ozone-free with no byproducts ever produced. Dirty air will first be pulled in through both sides of the air inlet.

The activated carbon filter focus on neutralizing smoke and musty odor created by the allergens.

Yet another expensive air purifier that is not meant for everyone. Airmega has a premium price tag to accommodate its long list of specifications. Thankfully there's plenty of good deals online to subsidize the price. As for maintenance, the MAX2 filter replacement will cost you around 100 dollars annually for both HEPA and carbon filters. It is required for the air purifier to function so that's something you need to ponder. Last but not least, the ionizer is surprisingly omitted here but that's not a big miss for most people.

In short: A wonderful mold removal air purifier that always comes with a great discount. If you're not into the ionizer, the mechanical HEPA filtration is more than sufficient to help curb your mold allergies.
