I have allergies and this works for me in our house.

Whenever these come on sale, i usually buy a package. They keep the dust down.

Great that I can get a 4 pack and continue regular maintenance on my A/C at home. Easy to install.

Love these filters, use them for my furnace. Keeps the dust down.

Really good filters! Much better than those 'rock catchers' I had been using.

Best price ! Normally about $18 for one filter

I am amazed at how much these filters collect compared to others.

You can never buy too many when it goes on sale right? What a great deal!

Good filter's and the price was great.

These were hard to find even in the home improvement stores.
