What Is the Difference Between Mold and Mildew?

Mold is a type of fungi, whereas mildew is a type of mold. The easiest way to differentiate the two is by their appearance.

Mold grows in green or black patches and penetrates underneath the surface of the affected material. Mildew, on the other hand, has a flat growth and remains on the surface. Unlike mold, mildew can easily be removed.

Also, mold mostly grows on structures such as walls or inside the food. Mildew grows on damp surfaces such as fabrics, papers, or other organic materials.

Although mold, mildew, and other fungi play an essential role in breaking down organic matter in nature, they are not beneficial in your house. They cause damage to the surfaces they grow on and can pose a health risk. Spores cause a more immediate threat.

Let me break it down for you.

Spores are microscopic units of all types of fungus. (like pollen produced by flowers) They range between 3 to 40 microns.

Mostly, spores float in the air and later land on surfaces. If the surface is icy, dry, or otherwise unsuitable for growth, then nothing happens. But if the surface is warm and moist, the spores start to grow into more mold. The mold will continue to spread and produce more spores. And the process continues.

Breathing in the spores can cause health problems such as; allergic reactions (skin irritation, coughing, nasal congestion), asthma attacks, inflammation, headache, sore throat ETC.

Can an air purifier help with mold and mildew?

Potentially! An air purifier can remove the mold and mildew spores from the air in your house. However, it will not solve an existing invisible mold and mildew growing inside your home.

If there is mold growing somewhere in your house, it has to be eliminated by physical cleaning, usually with detergent or bleach. Also, the source of moisture that encourages the mold to grow should be fixed.

The Go-To Type of Air Purification Technology for Mold and Mildew

The air purification technology in an air purifier is the first thing you should consider while choosing the best air purifier for mold and mildew. You will notice that there is a variety of filtration technologies that air purification can have. Sometimes purifiers have a combination of these technologies.

The truth is, not all technologies can effectively eliminate mold and mildew.

In this guide, we will look at the most suitable purification technologies for mold and mildew.

Let’s dive right in.

HEPA Filters

HEPA filters are AAP certified for effectively filtering airborne pollutants, including mold and mildew. A standard HEPA filter has been proven to remove particles as small as 0.3microns. Mold spores are larger than 0.3 microns, making HEPA filters effective.

For effective purification, you need to change the filters regularly. If the filters are clogged, there is a risk of the trapped growing on the filter surface and recirculating.

Also, beware of confusing HEPA filters with HEPA-type filters. There is a difference. For starters, HEPA- type filters only capture large particles of between 2 to 5 microns. This means mold and mildew will go right through the filter. Settle for True HEPA filters or Hyper HEPA filters.

Photo Electrochemical Oxidation (PECO)

This air purification technology uses UV light-activated reaction to destroy all pollutants that pass through the purifier. Its main advantage is that it kills the organisms and thus no possibility of growth or recirculation. This technology is also known to reduce Ozone.

Photocatalytic Oxidation (PCO)

This technology is a precursor to the PECO. A purifier that uses PCO can destroy all pollutants, including mold and mildew. However, unlike PECO, PCO is known to emit Ozone.

Ultraviolet Germicidal Irradiation (UVGI)

Devices that use UVGI are known for sterilizing the air by killing viruses, bacteria, and fungi such as mold. However, the EPA suggests that a UVGI air purifier has to generate more intense UV radiation than a home unit can be effective.

Ionizing Purifiers

Ionizers cleanse the air by imparting electric charge on airborne particles, making them fall and stick to nearby surfaces. This technology is useful for removing mold and mildew in your house. However, some proponents discourage its use as it produces Ozone.

Wrapping It Up

we hope you have found the information in this guide useful, and you have found an air purifier that fits your needs.

We would also like to remind you that although an air purifier will reduce mold exposure, it is not the cure. You need to find and eliminate it from its source.
