11 Best Air Purifiers: Your Easy Buying Guide

We all spend a lot of time indoors, either in our office or at home. Concentrations of pollutants, pollen and pet dander, can be worse inside than out. For those who suffer with allergies, that can mean feeling miserable during seasons with less pollen, but fewer hours to spend outdoors.

There are those odors we simply can’t live with. Whether it’s cooking smells, cigarette smoke, or other aromatic offenders, we want our air to smell fresh, clean and healthy. The best air purifiers can effectively create that environment.

True HEPA air purifiers address these issues. But after your initial cash outlay, you’ll want to budget for replacement filters. Some have washable pre-filters, which help extend the life of your True HEPA filter.

A few of these air cleaners kill viruses, mold spores and germs, and many create just enough white noise to guarantee you a peaceful night’s sleep. Our top pick is the Alen BreatheSmart Customizable Air Purifier that works fast and cleans huge spaces, although the Rabbit Air HEPA Air purifier was a close second.

If you’re ready to start breathing easier, check out our 11 Best Air Purifiers.

there are various kinds of helpful air purifier which is to necessary to our home. nice post tnx for your best review post for air purifier.

Paul

Note that the ionizer purifers (the tower ones I mentioned in this case) work a lot better in terms of making the air seem fresher. The HEPA one might technically filter the smoke, but the air still feels and smells very smokey to the point of being unbearable (at least, I’ve found that seems to be the case in my own experience).
