I need to get the dust, allergens and odors out of my home air, but don’t have a very big budget. A friend told me that Amcor has four units for under $100.00. That is my kind of budget. The AM40 and Am60 are under $50.00 but don’t have true hepa filters, so they won’t take allergens and mold spores out of the air. I decided to go with the more expensive AM130 Amcor air purifier because it will take over 90% of the particles larger than .3 microns out of the air and will service 200 square feet. I am putting the unit in the living room, kitchen area which makes up most of the living space.The Amcor air purifier should solve my problem.
