If you’re in the market for the best air purifier, your next move is to decide on why you need it. Should it be the best whole-house air purifier or the best large room air purifier? The Medify Air excels at being either-or, and for an excellent price. You can see this by its power and higher-grade HEPA filtration system.

Why We Like It – Medify Air

Handling a small office with ease, the Medify Air is perfect for purifying the air in very large quantities. On top of that, it uses a 4-stage filtration system and medical-grade True HEPA H13 filters for improved air quality.

  • 4-stage filtration system
  • 2400 square feet of coverage & possibly more
  • Higher grade H13 HEPA filter
  • Gets noisy on fastest speed setting
  • Filters add more invest

Power & Speed

The Medify Air has the kind of fan power to rival that of Dyson’s own lineup. This is because it’s running off of 95 watts of power. There are four different speeds to choose from Night Mode to High; however, its highest fan speed can get pretty noisy. For a unit with sleep mode, you’ll want to check out our GT 3000 air purifier review.


Place it in a room as big as 2400 square feet, and it’ll easily have the air sufficiently cleaned in an hour. This is unlike the InvisiClean IC-103 that only works for personal use. And if you drop its air changes per hour to just one, you can even clean a 3700 square foot area. What’s interesting is the fact that the Alen BreatheSmart Classic Large Room Air Purifier covers half as much square feet, but for the same price.


Like the Oransi Max HEPA Air Purifier, the Medify Air has a 4-stage filtration system. Larger particles are first captured by the pre-filter. Any smaller airborne particles (0.3 microns) then come face to face with the True HEPA filter. Toxic odors and formaldehyde are handled by the carbon filter, whereas the ionizer traps particles, preventing them from escaping back into the open air. But, do you know if your air purifier works with central air? There may be a huge difference.


Being tall and wide, the Medify Air isn’t easily knocked over, despite being made of plastic. It was built with thicker plastic, giving it great durability without making it weigh two tonnes. You couldn’t ask for a sturdier unit, unless you’re interested in a polyester unit like the OPOLAR EV01 Digital Evaporative.


The Medify Air is powerful, perhaps too powerful. If its performance is overkill, the Coway Airmega 400 covers 1560 square feet for $100 cheaper. But if you do stick to it, you won’t be disappointed; however, you do need to come to terms with the replacement filter costs. Outside of that, it’s worth every single penny.

Medify Air Wrap Up

The Medify Air offers power and efficiency, like so few do. Its airflow speeds are strong enough to cover 2400 square feet, sometimes more! And the air you’ll get to breathe is much more cleaner, thanks to its 4-stage filtration system, which includes a medical-grade True HEPA filter. Just know it’s a big investment and a bit loud at the highest setting.
