The Best Air Purifiers for Mold Reviewed 2017 – Buying Guide


The lowly mold. We need them to break down organic material, except for when you’re really looking forward to eating that piece of fruit only to find that mold already ate it ahead of you. Mold can be cool but not cool for allergies, your walls, and your health.

Much like dust, mold is everywhere. They thrive in moist areas, and mold spores are almost always present in your house or workplace. They’re found in the moist and dark corners of your house like the bathroom and different parts of the kitchen. Once mold growth gets out of hand, it can be a health risk for you and your loved ones. Large colonies can cause respiratory issues and in extreme cases, death from certain types of mold.

The Environmental Protection Agency (EPA) recommends that you do your best to control moisture in your home, especially if you live in a more humid area. While you can’t control humidity outdoors, you can lower your indoor humidity by making sure rooms are well-ventilated. Do this by opening windows and using exhausts in the bathroom and kitchen. Another effective way to improve indoor air quality is to use a dehumidifier or an air purifier for mold.

If you want to improve air quality in your home, you’ve come to the right place. Below are some air purifiers to help keep your indoor air mold-free. The list covers purifiers for different budgets.

The Top 3 Purifiers for Mold

GermGuardian AC5350B Elite 4-in-1 Cleaning System

The AC5350B is a game changer. This 28-inch tower purifier features five speeds, a true HEPA filter, and a powerful UV-C sanitizer. The carbon filter also effectively captures unwanted odors, while the HEPA filter is up to US government standards—it filters 99.97% of allergens like dust, pollen, and pet dander that are 0.3 microns small. Always look for purifiers that indicate the HEPA filters’ capacity.

To kill airborne bacteria and mold spores, the AC5350B uses a UV-C light. Some ultraviolet wavelengths are invisible to the human eye. UV light has different frequencies, and UV-C is a kind of frequency that can go through cell walls of germs, thus inactivating and killing them. UV-C can reach the bacteria’s nucleus or center and kill it to prevent it from multiplying.

The AC5350B’s CADR Rating is at 125+. CADR stands for Clean Air Delivery Rate, and this number is the best way to know how much space your purifier would effectively clean. To calculate, get the CADR rating and multiply it by 1.5 sq. ft. In this case, it’s 125 x 1.5 = 187.5 sq. ft. for the AC5350B. This means that this purifier is suitable for medium-sized rooms. You can still use this for rooms larger than 187 sq. ft. but note that it may have to run a few cycles before it cleans up the air.

This Elite Collection model has five fan speeds, with the highest setting being the loudest. Otherwise, from allergen control to sleep mode, the purifier operates quietly. The UV-C light is slightly visible, but it is smaller than GermGuardian’s other units. This feature is perfect for eliminating mold spores.

Filters need to be replaced every 6-8 months depending on use but overall, at around $149, you won’t regret buying this purifier. With its easy controls, filter replacement reminder, and effective multi-layer filtration, you’ll notice a difference in your indoor air quality.



Alen BreatheSmart Customizable Air Purifier

The customizable purifier from Alen Corp is pleasing to the eye and your nose, as well. This slim air purifier comes in white with silver detail and suits the modernist. It’s customizable in a couple of ways. One is the type of filter that you need. You can choose from four types of filters: HEPA-Pure, HEPA-Silver, HEPA-Fresh Plus, or HEPA-Odor Cell. Their HEPA-Silver technology was designed to trap allergens including mold. The second type of customization is the color. You can change it to complement your décor.

One downside is that this product has no CADR rating but the company claims it can clean up areas up to 1,100 sq. ft. in size. It does seem to work on larger and more open spaces. BreatheSmart operates quietly, and it also has SmartSensor that automatically changes settings depending on air quality.

You do get a lifetime warranty so that partly makes the $614 price tag a little more worth it. It is expensive, but if you need a high-tech purifier for bigger spaces that offer flexibility, the BreatheSmart is for you.



AeraMax 100 Home Air Purifier

A more budget-friendly yet also a high-tech option is the AeraMax 100 Home Air Purifier for Allergies and Asthma. If you’re allergic to mold, this could be the solution you’ve been looking for. It has four stages of filtration similar to the BreatheSmart and uses HEPA filters. Its filters can last for about a year and the carbon filter, up to 3 months. Bonus: it is certified by the Asthma and Allergy Foundation of America.

AeraMax 100 is ultra-quiet as it filters allergens like dust mites and mold spores. It even comes with a High-Performance mode for cold and flu seasons. The unit has an ionizer but no UV-C light like the GermGuardian Elite unit. Like the Alen BreatheSmart, AeraMax 100 does not have a CADR rating, but it is suitable for small to medium sized rooms. It also has AeraSmart Sensor that works in a similar way as Alen’s SmartSensor. If you like the BreatheSmart’s features but don’t need that much power, or you don’t have that much dough to spare, then the AeraMax 100 is for you.





Most air purifiers, as long as they use HEPA filters, should be able to filter mold and mold spores. Regardless of which brand you choose, what matters is the type of filter that’s included and the room capacity. We think the GermGuardian AC5350B model is the best purifier so your indoor air can stay mold-free at a reasonable price.
