5 Best Air Purifiers for Mold (2021): You can be reassured!

An efficient air purifier for mold for your house is of great significance. You may wonder why? Next Atomee will prove it.

Mold is among the TOP 10 sources of indoor air pollution!

Molds are ubiquitous, particularly gathered in large quantities in that high-humidity environment. The nasty fungi can grow and spread exponentially on almost any surface, and release mold spores into the air, causing cause great damage to our health in the long run.

Ever since discovering aflatoxin, a poisonous substance produced by certain molds, food contamination by molds and mycotoxins has attracted increasing attention as it would negatively influence human health.

Here’s why an air purifier for mold is important:

Risks like chronic poisoning, carcinogenesis, teratogenicity, and mutagenesis emerge. In addition, molds will cause various respiratory diseases as follows:

1. exacerbate asthma

2. coughing

3. snoring

4. bronchitis

5. rhinitis

6. sore throat

7. seasonal allergies

Thus an effective and viable solution is a must.

By the way, for your curiosity, another 9 sources are cleaner and disinfectant, passive smoking, gas stove, fireplace, carpet, home decoration coatings and building materials, cooking utensil, pet dander, and radon gas pollution in addition to the mold.

How to Stop Mold?

If you’re dying to figure out the best way to kill mold, you must have a basic knowledge about why mold grows at the very beginning. Only in this way can we kill it in the first place and get rid of this nasty fungi.

Mold loves moisture and can grow significantly indoor areas with high humidity in a short time. Therefore, immediate actions must be taken to prevent the reproduction of mold or cut off its transmission route.

In today’s blog, I will only recommend some technological devices.

#First a stand-alone dehumidifier is at the forefront. It can not only reduce and maintain the level of humidity in the air but also prevent the growth of mildew by extracting water from the air.

A dehumidifier placed in the living room can reduce the high level of humidity to an average level.

But that’s not enough. One should not expect it to go magically away on its own.

# An additional mold air purifier is a savior for mold-polluted rooms in this regard. An air purifier can remove mold, dust, smoke, and other particles that are already in the air and bring a fresh breath to you.

However, one point needs to be mentioned. Some experts claim that air purifiers won’t completely eliminate the potentially harmful fungi. Even the best mold air purifier can’t fix the root cause of them. Still, the good news is that enough pieces of evidence have proven that these devices can mitigate mold problems by reducing the number of dangerous spores in the air. So far better than nothing, I suppose.

An efficient air purifier can bring a fresh breath to you.

How to select an effective air purifier?

As is widely recognized, traditional air purifiers have a 3-stage filtration system, the pre-filter, the HEPA filter, and the activated carbon filter respectively.

The powerful True HEPA filter deals with 99.97% of any airborne particles down to 0.3 microns, including mold spores and some viruses. And the activated carbon filter mainly removes unwanted odors and compounds including formaldehyde, benzene, ammonia, and VOCs. In this way, when it comes to mold, the combination alone may not work well.

Here’s what experts recommend when looking for a mold air purifier to detect and prevent mold.

HEPA filter

The HEPA filter is internationally recognized as the most efficient filtration material and a powerful and effective weapon to trap microscopic particles. The HEPA filter has already been widely used in the operating room, animal laboratory, crystal experiment, and aviation, and other high clean places.

According to the Environmental Protection Agency (EPA), it can filter a minimum of 99.97% as small as 0.3 microns, including smoke, dust, mold spores, bacteria, viruses, and allergens such as pollen, dander, and mites.

UV light

Air purifiers with ultraviolet light often contain the words “air sanitizer” or “UV-C” in their product descriptions. UV-C is a safe form of radiation that will not harm human tissue, yet can kill airborne bacteria and viruses by breaking the molecular bonds that hold DNA together.

In general, regular UV lamps in our homes are a concern, while UV-C lamps installed in an air purifier are very safe and allow you to enjoy clean, sterile air. So don’t worry.

Ultraviolet lamps are, nowadays, used in our daily life to disinfect hospital wards, nursing rooms, operating theatres, and canteens.


It is of significant importance to make sure your air purifiers are certified. Common certificates are CARB, CE, FCC, ETL, and Energy Star.

Energy Star, for example, ensures a product meets the strict energy consumption standards put forward by the U.S. Environmental Protection Agency(EPA) and the U.S. Department of Energy (DOE).
