All stages of the filtration process of Medify Air MA-50 only involve eliminating particles, fumes, and bad odors in the air. On the other hand, the first three processes of Airdoctor 5500 involve all of the same ones with Medify Air, but the last part includes taking advantage of negative ions.

Airdoctor 5500's four levels of filtration

  • First Stage: Pre-Filter – When you enable the unit, it will first filter the air of the airborne compounds into its filtration system.
  • Second Stage: Activated Carbon – The compounds go through the activated carbon filters, which trap and eliminate VOCs, toxic fumes, bad odors, allergens, and other harmful pathogens.
  • Third Stage: HEPA Filters – The last filtration stage is when the unit’s HEPA filters eliminate the particles down to 0.003 microns.
  • Fourth Stage: Negative Ions – Finally, the unit releases negatives into the air, enhancing air circulation quality.

Now, below is a summary of how the three-layer filters of Medify Air MA-50 work:
