I really like these air filters. They really help especially during inversions, chimney smoke from neighbors fireplaces. I recommend them.

Thinking about furnace filters?

I don’t actually give much thought to furnace filters. I buy the size and the MERV the HVAC guy tells me to, and I don’t seem to have any air filtration problems, so I assume they’re working.

I have not installed the filter at this time. I'm guessing it may take a month to test

Love the way they have pretty much any size you need, quality is great. I receive my filters within a couple of days, if you have a problem or mix up they were gracious and do whatever it took to make it right! Great filters at a good price!

I realized I had used my last filter and the one in my furnace was old, so I ordered a new 6 pack immediately. The new box was on my porch the next day! Super easy website and fantastic quality and price. Keep it up!

Would be nice if u can add the weather strips around the filter to better prevent air leak thru.
