Best Air Purifiers for the Basement

Basement air purifiers are the best solution for the basement, because in the basement humidity is high, and mold is growing everywhere. There is not enough fresh air, and most of the basements don’t even have a window to let fresh air in the room. Because of that if you wish to have clean air and no mold in your basement, you need to use an air purifier.

But not every air purifier will do the job at removing mold and keeping the place at a clean state. You need to look at air purifier that uses true HEPA filter that is capable of removing 99.97% of airborne particles.

That kind of air purifier will remove mold spores from the air and in the process eliminate mold in your basement. Once you remove mold in your basement, you need to use a dehumidifier. Some basement air purifiers have this option and are an excellent choice for a cellar. A dehumidifier will make sure that your basement is not having a high level of humidity which helps mold grow. Mold loves damp, dark places with high humidity and if you remove moisture from your basement mold will be gone.

Why Should You Use Basement Air Purifier?

If you accidentally got on this article, you are probably thinking that a person who spends so much money on a basement air purifier is crazy. Who would invest such money for a basement that rarely gets visited? Not all basements are the same, some homes have clean basements and putting an air purifier in that type of basement can have huge beneficial factors for the whole house. For example, if you place a decent basement air purifier, you can prevent accumulation of mold and mold spores in an entire home.

I understand that people who have filthy basements with no glass on the windows won’t spend a dime on their basement, but some homes have clean, productive basements where they store food and other things they regularly need in the house.

Are Air Purifiers Good for Basement?

Air purifiers in the basement are an excellent product to reduce mold and mold spores. Air purifiers are powerful to remove mold, and by that, it is better to fight with mold in the basement instead of in the bedroom. In the basement, you can have a long passive war with mold while in the bedroom you need to remove mold as soon as possible or your health problems can get worse by breathing mold spores while sleeping.

In many old homes, the mold is already in the house, but the source of all that mold is coming from the basement. It is better to prevent mold from coming in the basement and in that way prevent it from entering the house. Mold loves damp places like basements, and if it starts to grow in such a lovely dark and damp place, then it is only a matter of time when it will enter the rest of the house.

Benefits of Air Purifier with Dehumidifier FOR BASEMENT

Dehumidifiers are one of the best ways of reducing humidity in the rooms. Most of the time these devices are used in rooms with high humidity where mold could grow. A dehumidifier is used in the kitchen, bathroom, and basement. These are the rooms with the highest concentration of damp areas where bacteria and mold can grow. Dehumidifiers have no power of filtering the air, and because of that, they are mostly used with air purifiers. Air purifiers job is to remove airborne particles from the air and in this case eliminating mold spores that mold release to grow on other places.

Dehumidifier job is to reduce humidity and by that remove mold by not allowing it to grow. Because of that features the combination of the dehumidifier and air purifier is an ideal solution for wet basements. You can read more about best air purifier and dehumidifier on our previous article written a few months ago.


There is no favorite among these air purifiers, and everyone should choose on their own the best one that fits them and their budget. Whichever you choose it will do a good job. After all, it is better to have an air purifier and clean some air than no air purifier and accumulation of mold spores. For larger basement look for more stronger and bigger air purifiers that are capable of filtering air from larger rooms. Some of the air purifiers mentioned above have special filters which are working slightly better than ordinary filters in ordinary air purifiers. Some air purifiers even use some additional technology which may help in destroying mold from your basement.

Remember to keep your basement clean, fresh and free from the mold you need to hold it at low humidity levels. Most of the air purifiers will not do this on their own, so you need to get a dehumidifier as well. An air purifier primary job is to destroy mold spores and by that prevent the mold from spreading over the whole basement. If you have a bad smell in your cellar, you should look for an air purifier that has the option to remove bad odor from the air. Most of the air purifiers with activated carbon prefilter will do that job just fine. It is on to you to choose which air purifier best fits your needs, but if you select any of the above mentioned, you will not go wrong.
