  • Heoa filters

    These are great and do a great job! I have a cat and a wood burning fireplace, and both give off a lot of impurities. I would highly recommend!

    These are really great air purifiers. I have a small apartment. I placed one in my living room and one in my bedroom, and they are working great. This was an important investment for me because during the winter months here in Michigan, I am home quite a bit (I hate the winter months), and although I have a filter connected to my furnace, I felt it was crucial for me to have these air filters in my apartment. They are providing much needed additional air filtration in this apartment for the heat coming through my vents that my furnace filter cannot do.

    Quiet filtration system. Great to keep my pet dander down. So much more comfortable without a stuffy nose
