Best praise vs top criticism for Medify MA-112
Best Praise
+4 pts“Brands we recommend: Coway, Winix, Medify, Levoit Vital. Brands I personally don't recommend: Levoit Core, Dyson, Shark, Xiaomi. Contentious Brands: Blueair. They are without question the best at cleaning air in their price category, but they aren't HEPA and they use a static charge. Some people really distrust that or don't like the air that comes out of them (I use them in my home, though). Also their marketing practices are shady. But again, if your concern is having ONE UNIT that cleans air REALLY WELL, it's hard to argue with the numbers. I'd avoid anything ROUND in the "under $500" range (with the possible exception of Blueair), due to that design just being badly engineered.”

+2 pts“A few things. * First, the sound levels are (still!) **incorrect** on the [MA-112](https://medifyair.com/products/ma-112?variant=31240021180483)'s product page and in the owner's manual. I contacted Medify Air's customer support and was told the max sound level is 70 dBA which is very loud. This was September 2024. [See the screen capture of their e-mail here](https://imgur.com/c3KX2Tz). * I don't think the "True" HEPA H14 filters are worth it. The listed Clean Air Delivery Rates (CADRs) are for the "True" HEPA H13 filters; the "True" HEPA H14 filters will have lower CADRs. * Lastly, the 4,455 sq. ft. coverage rating is misguided. At that square footage, there is only 1 Air Change per Hour (ACH). The *minimum* number of ACH we recommend is 4.8-5. So in reality, the coverage is 921 sq. ft.\* at 4.8 ACH for the AHAM Verifide rating. \*Looks like Medify Air's value of 928 sq. ft. at 4.8 ACH is slightly off. To calculate "Suggested Room Size", AHAM Verifide technically uses 4.84 ACH in their calculations.”
