  • Perfect for home with Pets!
I recently purchased two for my home. We have 5 indoor cats and 3 dogs. These filters are a game changer. Work great!

  • Air purifier
It cleans the air, it is noisy and the air coming out is cold, cold, cold. It brings the warm air temperature in the house down. It will be great in the summer months.

So far so good. I’ll get back to you. Later……….

  • Not the same thing as the one I bought in 2020
Not the same one as the one I bought on Medify site. The model is the same but it is slightly different. The worst is Medify Air seems to be losing engineering tolerances and quality. A filter I got from them directly for MA14 was bad and for THIS one, the machine itself just buzzes all the time

  • Needed in every household
I purchased 2 of these after Covid. I have added 2 additional units, one in my elderly mother’s room and in my room to help with allergen with my pet family. Easy filter changing!!!

  • Very quiet and efficient
Very high-end look and functionality. Whisper quiet on low setting.

  • Filters are expensive
These are nice but the cost of the replacement filters is outrageous. Just for one it’s about $60 every 3 months so 120$ every 3 months
