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

I feel confident that this filter does a great job.

Duel pack awesome for such a good product!! would buy again

I have used this filter for years now and have had good results each time.

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

I bought it before winter and it's still going strong

Suction kept collapsing filter. Not strong enough.

Filter is much better than the old thin filters. Works for six months very efficiently.

Excellent product, haven't been sneezing as much since replacing filter.

This filter really helped reduce fine dust particles on household surfaces.
