Best Air Purifier For Mold 2020 in Basement & Apartments

We all live in a habitat that is continuously damaging the raw air upon us in one way or other. Let’s share some words on one of the air spoilers out of many, that is, mold.

Mold is a kind of fungi that leads a substantial helping hand in disturbing the natural air flow.

For instance, if you leave any kind of food, be it vegetable or fruit, in open air for as many days, you will see the process of mold formation with a piecemeal. It rots and rots until it transforms into a total decayed fungus.

The color can be dark green, dark brown or silver black. This mold then grows in the form of multicellular strands called hyphae.

Keeping the eatables aside, there are many other unnecessary household articles that cause the ultimate production of mold.


One biggest exposure to this particular microbe is our underground basements. Such closed and away-from-light places fasten the process of development due to less use, more dust, and dampness in the area.

The mold scatters and reproduces greatly by generating spores in the air and thus the cycle begins.

These pollutants have been alarming to human health since ever and set off a heap of allergies and infections.  These may include coughing, sneezing, shortness of breath, skin itchiness and many other afflictions.

If that is the situation, there is one and only one solid suggestion and that is an air purifier for longer and permanent terms. The air purifiers act against every kind of microbes including the mold spores and provide breath worthy uncontaminated air in return.

Here I have listed some of the best air gadgets that are entitled to be perfect in the case of mold spores and basement cleaning.

Some Frequently Asked Questions

How long does it take to get sick from mold exposure?

Mold is everywhere, even where you expect it to be least or not to be at all. The problem is not your direct or indirect contact with the mold but how long this contact remains.

The average performing range of an air purifier to work wonders for the deteriorated atmospheric condition should be around 10 to 12 hours and that is for low to the medium environment.

The extra worst condition may ask you to let it run every time.

Do air purifiers remove cooking odor?

This is the versatility of a competent air purifier to take hold of whatever your home air has to offer.
