Since I started using this filter, I stopped getting sinus infections and suffer less from allergies! Great product. You can feel the effects of putting in a new air filter immediately.
I used to try and save money on filters until I bought Filtrete. These filters are fantastic. I can see the difference and don't mind spending more for these great filters.
I decided to up spend on this filter and glad I did. I feel a piece of mind knowing this filter is on the job filtering the air thru my 4 bedrooms and 2 bathrooms on the upper level. Will re-purchase when I get the automatic reminder telling me its time.
This is the best filter for keeping the animal allergens under control. I put in a new one in the furnace yesterday before relatives with dog allergies came over and they had no problems the entire evening. So great! Better, too, for us non allergy people to not be breathing in all those minute particles.
