This GermGuardian air purifier is on sale for 50% off on Amazon

We were all waiting for March for daylight saving time to start, but with March also comes something not so fun: Allergy season.

And if you’ve had a hunch that it’s been getting worse every year, it is. But hey, at least you’re not crazy.

Combat the sniffling with something more powerful than a box of Claritin: This 22-inch air purifier and HEPA filter from GermGuardian is $70 off today — and when you clip the extra 10% coupon, it drops down to just $71.99. That’s over half off.

The name “GermGuardian” may seem corny, but it’s literally what this thing can do for a room (up to 167 square feet). The HEPA filter captures 99.7 percent of allergens like household dust, pet dander, mold spores, and plant pollens, even as small as .3 microns. Not only is it cleaning the air by trapping particles you can’t even see, but it’s making it smell better, too. The filter battles odors like cigarette smoke, litter boxes, or overly-smelly furnaces to provide a fresher feel every time you walk into the room.

If you’re extra worried about germs, turn on the UV-C light sanitizer. This technology works with Titanium Dioxide to pull in airborne bacteria, viruses, germs, and mold spores, kill the harmful stuff, and spit cleaner air back out.

“I’ve been using GermGuardian air sanitizers for years.. the most impressive thing I can tell you is I haven’t even had a cold in all that time. Every room in my home has at least one unit of some kind. This all started after radiation treatments following cancer surgery, when I was warned my immune system would be affected, well it may have been, but these units have kept me in perfect health! I can’t say anything better than that, they work! They not only sanitize the air, they also kill mold spores, so there is one in my basement as well.. and the house always smells so fresh, even with multiple cats in residence! I highly recommend GermGuardian products and wouldn’t be without them. Keeping the air clean and germ free has insured my good health for years!”
