[This review was collected as part of a promotion.] I usually use the Clean Living air filters, which I replace every 1-2 months. Yesterday I replaced it with the Allergen Defense Air Filter. Prior to changing the filter I was miserable with allergies and coughing all the time. Today my cough is 95% gone. Yay!
When I first started using these filters I immediately noticed a reduction of dust in the house. I went from having to dust once a week to about once a month or longer depending on the room. If you suffer allergies from dust, pet hair etc., you will notice a significant improvement. We use Filtrete Allergen Defense 1200 MPR.
This is a very good quality filter. It does a fantastic job of filtering out allergens and dust. With routine filter reminders from Filtrete, the heating/AC unit does not have to work as hard either.
