The Arm %26 Hammer filters are a really good buy.

The Arm %26 Hammer filters are a really good buy. They are sturdy not flimsy at all. They fit our . ceiling register well. They are very quiet due to the good fit. I have noticed less household odors and less dust on furniture since we started using the A%26H brand. They came in a sturdy box with zero damage. The lowest price for an Allergy MERV 8 filter I could find and it works GREAT!

Very impressed.

I am impressed! I was buying the more expensive ones for a few years and knew it was time to change the filter again and I had to budget tighter but still needed a good one. I am amazed this one is better than the more expensive ones. I will purchase again.
