Powerful Performance for Large Spaces

The MA-112 packs a punch with a Clean Air Delivery Rate (CADR) of 5,000 sq ft in 60 minutes. This translates to clean air for large open floor plans, whole homes, or even basements. Independent testing shows it effectively removes 99% of airborne particles and significantly reduces PM2.5 (fine particulate matter).

Multi-Stage Filtration for Comprehensive Cleaning

The MA-112 employs a 5-stage filtration system to tackle various air pollutants:

  • Pre-Filter: Captures large particles like dust and pet hair.
  • True HEPA H13 Filter: Traps microscopic allergens like pollen, dust mites, and pet dander.
  • Activated Carbon Filter: Absorbs smoke, odors, and volatile organic compounds (VOCs).
  • Optional Ionizer (Electrostatic Air Cleaning): Negatively charges particles to improve capture by the filter. (Note: While ionizers can generate ozone, a potential respiratory irritant, Medify claims theirs produce negligible amounts.)
  • Optional UV-C Light: Kills bacteria and viruses on the filter (not airborne).

Additional Features for Convenience and Control

Potential Drawbacks to Consider

  • Size and Weight: The MA-112 is a large unit that may not be ideal for small spaces. It's also quite heavy, making portability a challenge.
  • Noise Level: While the lower fan speeds are quiet, the highest setting can be noisy.
  • Replacement Filter Cost: True HEPA filters need periodic replacement, adding to the ongoing cost of ownership.

Filtration Technology

The MA-112 features a dual True HEPA filter, which provides enhanced filtration capabilities. The True HEPA filter is a standard in the air purification space, known for its ability to remove virtually all particles (99.9%) down to 0.1 microns. This technology is particularly effective in capturing particles that are most difficult to filter out, such as those around 0.3 microns in size
