I've been using these products for over 10 years. I will search out stores that carry them and have been pleased with the increased efficiency levels the company keeps producing.

I have used the Filtrete air filters for many years. They have definitely helped with allergies in our home. I can actually tell from how fresh the air is when it is time to replace.

I have brought several of these filters after Katina we had a lot of dust in our home from replacing the sheetrock and these filters have made a big difference.

For the second time in a row, when the air flows to the air conditioning unit, this product literally falls apart. It separates from the flimsy cardboard border.

With 3 dogs, 2 cats, kids and husband, I need all the filtering I can get. I notice when I forget to change it. Air conditioning was boggind down. Bill seems more.

I have used these filters for years. They say they are good for the whole year, though I still change mine out every 6 months. Ordered through Walmart as they were the only place I could currently find them amidst all this COVID crap going on

Over the years we have tried dozens of filter, since we switched to Filtrete we have not tried any others. This product works, we have cats, dog, and it keeps the air clear and fresh.

If only installed the filter a month ago, therefore the 4 star rating. Once it's been in for 6 months I'll see how it performed compared to the others I've used.

We have been using the Allergen Defense filter for over a year and I have noticed a dramatic reduction is the particals of dust in our house. That means less time I have to devote to dusting the floors and furniture.

Remember these filters are for Standard size Returns. However there are HVAC companies that deliberately use Grille size Returns to make a customer buy their filters. GRILLE SIZE Returns are slightly smaller than the Standard counterparts.
