Air Purifier For Basement – Top Pick

But not every air purifier will do the job at removing mold and keeping the place at 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 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.

Final Verdict

There is no favorite among these air purifiers. Whichever you choose it will do a good job. 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 choose any of the above mentioned, you will not go wrong.
