Difference Between Mold and Mildew
Before jumping into the product Reviews, let’s take a short look at mold and mildew difference.
Mildew refers to a specific type of mold, while a mold is a fungus that can grow in different shapes and colors like black and green. Mold can penetrate below the surface and affected materials. On the other hand, mildew can grow on a flat surface and cannot penetrate through the material.
Furthermore, Mildew is found on the home’s organic materials like paper, texture, and fabric. Mildew requires a specific environmental condition to grow; it cannot succeed without a moist environment. A particular humidity level from 62 to 93 percent with a temperature between 25oC to 31oC is ideal for growing mildew.
Important Note: “Never mix bleach with ammonia or other cleaning products; it may be the cause of toxic fumes and harmful gasses.”

Every filter has a specific function; before selecting the best air purifier for mold and mildew, take a look at a different type of filters; which one is the best to get rid of mold and mildew?
HEPA Filter: (High-Efficiency Particulate Air) is the primary type of filter used in air purifiers. HEPA filters are made with fiber; these filters can catch particles up to 0.3 microns and clean the air up to 99.97%. HEPA filters are the best to capture mold spores from the perspective. HEPA filters catch most mold spores because most mold spores are large than 0.3 microns. But there is some problem with HEPA filters when they capture mold spores; these spores start growing on the fiber surfaces and discharge more spores. HEPA filters are not washable, and they are changed after a specific time; that’s why mold spores start growing to form the filter surface.
PECO: Photo Electrochemical Oxidation filters are used to destroy indoor air pollutants despite trapping them through filters. Each filter is coated with a nanocatalyst that meditates an oxidation reaction and kills contaminants in the air. PECO technology is also best to destroy the mold spores when passing through the device.
PCO: Photocatalytic Oxidation is an upgrade version of PECO technology; it can break organic molecules like mold spores and VOCs. Some people consider this technology inefficient, while some claim that PCO breaks mold spores and eliminates viruses and bacteria.
