Filters completely clean out Vaping smoke from my home.
on March 26, 2026
Posted by: Customer
The filter buy air filters are as good as any name brand, half the price, which allows you to change the filters more often. These Filter Buy filters work well. My filters, upon changing, are coated with dust and lint and oil from my Vaping. They clean out the vaping smoke so that, after a few minutes of the AC use, the Vape smoke is undetectable in my home. If the Filter Buy filters did not do as well as they do, cleaning out Vape smoke, my walls would be ruined from the Vape smoke.

The filters are great. I don’t have air conditioning so I only use my furnace three to four months out of the year. I change the filter once a year and I have 6 in stock now.
Please discontinue any future automatic purchases. I’m looking forward to your response. Thank you.

Cheaper because they are smaller?

These filters are smaller than the 20x25x4 Honeywell filters I had been purchasing at the big box stores to the point they dont really fit very well.

16x20x4 filter review

The filter is so undersized that I had to use the Honeywell case so it would not fall off the support rails. If I buy again, it would have to be a custom size. Which doesnt make sense to me.

I have ordered before. I have a service that checks my ac a couple of times a year. I like to have your filters ready for the air cleaner. Makes all the difference
