Product Overview

The Medify Air MA-40 Air Purifier blends upgraded technology and modern design for quality long-term air cleaning. 

Its affordable price also makes it a perfect choice for rooms up to 800 square feet.

This HEPA air purifier uses a PM2.5 sensor to analyze your air and adjust its fan speed automatically. Your air quality also displays on the front of the unit with a colored light bar, so you can trust it’s working to remove dust, dander and microscopic particles you can’t see.

Lifetime Warranty: On parts and service as long as the filters are changed every 6 months with genuine MEDIFY AIR filters.


A front-facing light changes color based on your current room air quality (blue-green-red). As the MA-40 cleans your air, you'll notice the light change from red to blue as the air quality becomes free of allergens, dust, and other harmful particles. 


The Medify Air MA-40 uses four levels of filtration to catch and remove allergens, pet dander and more:

  • Pre-filter removes hair, fibers and large particles like dander.
  • The high-efficiency H13 HEPA filter is tested to removed 99.97% of particles down to 0.3 microns. This medical-grade filter easily catches pollen, dust mites and other tiny airborne particles you can’t see.
  • A substantial carbon filter with carbon pellets removes toxic odors, smoke, and formaldehyde.
  • The optional anion generator produces negative ions to charge particles and trap them inside the unit and give your air a fresh feel.  


Access the touchscreen from the top of the unit and have complete control on your room’s air quality.

  • Choose one of three fan speeds or the Auto mode for thoughtless air cleaning
  • See the filter replacement indicator
  • Set the off timer (1, 2, 4, or 8 hours in advance)
  • Turn on the child lock on or off to keep children from changing your settings


  • Compact and Easy-to-Move: Don’t fall into the trap of a bulky air purifier. This one stays out of the way and can easily be moved to different rooms with its handle. 
  • Night Mode: Use this mode for quiet particle remover as you sleep. 
  • Simple Filter Changes: All three filters come in a single cartridge for simplified replacement and reliable air-tight seal.


The Medify Air MA-40 Air Purifier breaks the rules when it comes to most air purifiers. It’s packed with upgraded technology, compact and sleek, and removes airborne particles you can’t see.
