What we’re saying is, when you look across all the categories, we outperform HEPA. At the February 2020 New York price of 20.1¢ per kilowatt-hour, that works out to a little more than $14 a year.

We cannot recommend either Dyson purifier, especially given their high price relative to those of our much higher-performing picks. The Inofia PM1320 claims to work in rooms as large as 800 square feet. The Philips 1000 Series purifiers cost more and have similar or weaker specs compared with our Coway top pick. At a certain point, these results look worse than what you see with no purifier running at all. 5.0 from 31 reviews.

Both of those numbers fall well below our 50-decibel limit for “quiet,” but the difference is readily audible, especially when you’re going to sleep or watching TV. The smaller Medify MA-40 has specs similar to those of our top pick, the Coway AP-1512HH Mighty, and in fact it achieved the same reduction in particulate pollutants: 98.9% on high. The numbers get worse when you factor in running costs: five years of running the Coway on medium and replacing the filters on schedule will max out at around $265, and less if you don’t pay the high New York electricity rates we base our calculations on.
