1. The purifying system has to be capable to release the air from mold spores

It’s essential the device should have several stages of cleaning. The cooperation of various technologies guarantees perfect results in mildew removal.

The chief in this process is the True HEPA filter. This technology is certified to capture up to 99.99% fine particles with their minimum size of 0.3 microns. Thus it’s exactly fitting system to catch the mold spores as they are usually sized 1-40 microns. More budget-friendly but less reliable are ordinary or like HEPA filters.

The filters with Activated Carbon are irreplaceable in musty odor absorption. They perfectly manage with toxic microbial and volatile organic compounds which fungi secrete.

A useful supplement is an Antimicrobial filter. It not only finishes off the mold residues but also prevents the growth of harmful bacteria on HEPA filters. It helps to save the efficiency of air purifier.

The Ultraviolet (UV) light is one more important fighter with mold spores. Its target is to break the DNA of fungi. As usual, UV is designed with safety for people.

This feature is an excellent supporter for HEPA filter to win the battle with mold spores in the air.

2. Appropriate power

It’s one of the key criteria when buying air cleaner for mold. The device should be strong enough to protect the required area and volume. Check the offered footage it can perform thoroughly. Accordingly, the purifier which is able to cover 400 square feet is suitable to eliminate mildew spores in the rooms below this figure. Placing the too powerful machine in smaller apartments will not bring faster and better results.


Clean air delivery rate (CADR) informs how fast the mold air purifier will do its job in a specific area. The higher this index is the faster mold and other unwanted things it removes.

Air changes per hour (ACH) indicate the frequency of the air rotation per hour. If the fan passes (circulates) the air over the filers more often the indoor atmosphere will be cleaner.

4. Price and maintenance cost

Of course the cost of air purifier that removes mold matters. But there are hidden expenses for the support that should be taken into account too.

So it’s worth to know the term of warrantee and quality conditions of technical support offered by the manufacturer. The other issue is the filters’ replacement charges. It’s better to know in advance the availability of spare parts and how costly they are.

Keeping in mind the above information it is easier to avoid any disappointment after purchase.

How Do Mold Air Purifiers Work?

Mold air purifiers have multi-stages filtration cleaning system. Each part of the machine has a special responsibility. After the activation, the air comes inside the tool. The strong fan rotates the air over several filters. Step by step the mold spores and other unwanted fragments disappear. As a result, clean and safe air goes out of the device.

The first barrier is a preliminary filter. It stops the bigger contaminants. The real mold killer is HEPA filter. It is capable to catch 99.97% of small fungi particles sized 0.03 microns. The life forms of mold are larger. It means that HEPA technology manages them easily. Meantime filter with activated carbon absorbs mold odor and other smells.

After the filters, UV light kills the rest of mildew spores, bacteria, viruses, and other dangerous organisms in the home environment. Ionizer deals with grouping together fine residuals. So they become larger and heavier, then the filters can capture them all. Therefore features of Ionizer and UV light are the other great assistants to beat allergens.

Definitely, modern mold air purifiers are a foolproof defender of the home environment from the mold.
