Best praise vs top criticism for Medify MA-45
“The [Medify Air MA-45](https://medifyair.com/products/ma-45-air-purifier?variant=39635123667011) will do little for VOCs. It's designed for particulates and has little activated carbon by weight. Generally you need pounds of sorbent media for VOCs (or gases, vapors, or odors). The cheapest non-DIY unit I'm aware of is the [Oransi TrueCarbon 150C](https://oransi.com/products/truecarbon-150c-air-purifier). It uses 3.2 lbs. of potassium permanganate (KMnO₄) impregnated activated carbon. It's on sale for $269.99 at the moment. Oransi also sells a [Wall Mount Accessory for AirMend and TrueCarbon](https://oransi.com/products/wall-mount-for-airmend-and-truecarbon) ($49.84). If you go to most Oransi product pages first, there's a pop-up that eventually enters from the right. Sign up and you should get a code to save 15% on your order (new subscribers only).”
