Top notch product with the quality and durability you expect from this brand. Just buy if you need it...

Excellent filtration. I have hay fever and sinus problems and these filters have kept my problems to a minimum.

Great value I’m so happy to get them on sale! It’s nice to have the good stuff during pollination season!

Have bought these for years. And replace regularly. Have two cats, and a lot of dander. these filters keep my a/c, heating system clean.

These look to be very good. But they were on sale this month but did not get the sale price when I ordered on line!

This filter makes a huge difference in our ability to breathe in a dusty climate and during times of high pollen. Great product.

Great filters at a great price! I have allergies and use these filters to cut down on pollen, dust and dander in the air!

These work well in our HVAC system and do not cause the "whistle." However, I bought them in June, and they went on sale in July for $5 off.

Keep up the great service. Recommend this service to all. If you need something quick try ordering from Sam's.

I have a hard time finding my size of filter. I want one that will help block more dust like this one seems to be doing.
