These filters will filter 99.97% particulates from the air if they are HEPA-certified. These pollutants can all cause respiratory disorders, asthma, or allergies.

HEPA filters usually consist of fiberglass and polymer threads. Because they are so tightly woven, pollutants cannot pass through. Remember that these devices do not remove or add moisture to the air. This unit’s only purpose is to eliminate air pollutants.

The issues listed above may occur when the relative moisture is lower than 30%. Mold and mildew can be a problem if you have a humidity level above 50%.

You may not be able to lower the humidity levels in your rooms for whatever reason. In this case, it is best that you invest in a quality air purifier. When these units are running, they can filter mold.
