Definitely helps to reduce allergens and irritations!

I purchased 4 at a time. I change the filter regularly. It work great.

I bought a bunch of them to keep on hand. I have asthma and a cat and it filters well.

High performance filter, keeps air handler and house clean.

I have used these filters for years and would not buy any other kind.

I used these in my home, great filter, better than others I have found.

Have used these filters since furnace was new and love them!

i HAVE A GERMAN SHEPARD AND THIS FILTER IS THE best THAT I HAVE FOUND FOR A 3000 SQUARE HOME

I have used this filter since 2011. They kept my air clean and dust down.

The only filter I ever use. Far better than anyb of its competitors.
