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.
I trust Filtrete to do what it says. As a single mom raising a little one in an older home - it is important that we have clean air. I also like the allergen and the dust filters. Working better than all the other brands. Thank you.
I've tried twice to submit a review, twice I've been told it is NOT valid. Guess I will start looking for different filters. Care to tell my why my previous submissions were not usable????
