We all spend a lot of time indoors, either in our office or at home. Often concentrations of pollutants, from pollen and dust to animal dander, are worse inside than out. For those who suffer with allergies, that can mean feeling miserable during those seasons with less pollen, but fewer hours to spend outdoors. Then, there are those odors we simply can’t live with. Whether it’s cooking smells, old cigarette smoke, incense or other aromatic offenders, we want the air, especially in our homes, to smell fresh, clean and healthy. The best air purifier can often effectively create that kind of environment.
That led me to examine the world of air ionizers, True HEPA air purifiers and other tech innovations that might address these issues. I was surprised to find out that, after your initial cash outlay for many of these devices, you’ll also need to budget for replacement filters. Some actually have washable filters, which seems a plus, while a couple of the devices we reviewed are actually filterless air purifiers, another bonus.
Probably the most surprising thing, was discovering that a few of these amazing air cleaners us UV light technology to to kill viruses, mold spores and gems. That alone makes them a worthwhile investment, compared to spending days in bed with some nasty bug, or missing lots of work due to sick little ones. As an added benefit, many of them create just enough pleasant white noise to guarantee you a peaceful night’s sleep. In addition to minimizing stuffy sinuses, you’ll likely wake up to less puffy, scratchy eyes. That’s guaranteed to make you feel better, while you look better too.
For the purposes of this review, we wanted to identify the very best air purifiers available. Some cover smaller indoor spaces, while a few actually purify up to 800 square feet or more. All models considered rated higher than a four on a five point scale. We’ve also carefully analyzed consumer comments before making our selections. So if you’re ready to start sneezing less and breathing easier, check out our top 10 recommendations to find the one that’s right for you.
