Long description

Imagine a home where the air feels fresh and light, free from lingering smoke, pet dander, or pollen that irritates your family.

The Medify MA-40 purifier makes this simple with its three-stage filtration: a pre-filter traps hair and large particles, a True HEPA H13 layer captures 99.97% of airborne contaminants as small as 0.1-0.3 microns, and a substantial carbon filter tackles odors and VOCs.

With three fan speeds, sleep mode for quiet nights (as low as 40.5 dBA), a 0-8 hour timer, filter indicator, and an intuitive tempered glass touchscreen, it fits seamlessly into your life.

Cleaning 896 sq ft every 30 minutes at 2 ACH, with a powerful 406 m³/h CADR—it's great for allergies, pets, wildfires, or everyday pollutants. Ozone-free and ENERGY STAR certified, it's built for long-term trust and cleaner air you can feel.
