Washable permanent filter 20x22

Comments:

This filter did not fit in a Trane unit without my husband filing down some areas within the unit. Non permanent filters with cardboard edges fit in better. We are happy with the filter once we modified the interior of our unit. I recommend this product as long as you are handy and can modify the fit.

BOTTOM LINE: No, I do not recommend this product

good filter

Comments:

The filter arrived in good condition and fit exactly as advertised. It seems to be omni-directional which is different than my earlier ones and requires more frequent cleaning but looks like it will do a fine job. Price was right as well.

BOTTOM LINE: Yes, I recommend this product

Best Filter Ever!

Comments:

I'm using the filers on a LOFT TV studio where bands record and play live with a small studio audience. In the past the 30-day filers never really cleaned the air. When I installed these filters after a week..the JBTV studios had a noticeable improvement in the air quality. Very pleased, plus never have to change a filter again. Simple to clean and can't wait to save time and trips to buy 30-day "old-fashioned" filters.

BOTTOM LINE: Yes, I recommend this product

Awesome Filter But...

Comments:

Although, the filter at the website said it was for a Trane,and our trane is less then one year old. I had to alter my air handler to get it in, I had to file down 4 bumps in the channel to get it to slide in, as it was just a little to thick,with the nice metal frame even though it was the correct size and for a Trane. Many folks would return it, not knowing how to alter the unit.

BOTTOM LINE: No, I do not recommend this product
