Summer allergies are probably the last thing on your mind right now as the contiguous U.S. gets slammed by winter storms and low temperatures, but pollen season will be here before you know it. Though we can’t help you brave the Great Outdoors without sneezing so much that people avoid you like the plague, the Medify MA-40 Air Purifier can at least save you from irritating particles in your own home.

With a H13 True HEPA Filter, the Medify MA-40 reduces dust, odors, dander, bacteria, smoke, mold, mites, asbestos, and more from an enclosed space of up to 840 square feet. It has a clean air delivery rate of 380m³/h, which basically just means that it’s both powerful and efficient. It will clean large spaces up to 1,600 square feet in one hour, or 840 square feet in 30 minutes, removing 99.9% of airborne particles.

In our pandemic times, that’s more of a selling point than ever — the MA-40 filters particles as small as 0.1 micron. For reference, the coronavirus has a diameter of around 0.125 micron. That means that this air purifier is effective in capturing airborne viruses such as COVID-19 in an enclosed space. The EPA has supported the fact that powerful air purifiers “can help reduce airborne contaminants, including viruses, in a home or confined space.”

But that doesn’t mean an air purifier is adequate protection against disease. As Wirecutter has reported, while having one reduces the infectious particles in the room, it may not rid the room of virus before you inhale if you’re very close to a contagious person. So the Medify MA-40 is by no means a substitute for vaccination, frequent hand-washing, or masking, but it certainly doesn’t hurt to reduce the amount of contaminating particles in the air.

The Medify Air brand was female-founded and “inspired by parents who wanted to provide relief to their daughters suffering from asthma,” and its products have plenty of features that take both medical and parental concerns into account. The MA-40 in particular is powerful enough to substantially improve air quality, but also has three fan speeds, the lowest of which is almost silent and will allow the machine to run quietly in your child’s room without disturbing their sleep. It has a child lock as well as a sleep mode, which dims the lights on its panel.
