Washable Filter

Comments:

My air handler was designed so that only paper filters would slide in, the metal frame could not flex. I had to send the filter back, easy return process. They have my business. Make sure your air handler doesn't have any restrictions.

BOTTOM LINE: Yes, I recommend this product

I have bought a permanent washable filter from National Trade Supply, an odd size that I could not get in Ocala, Fl. In any of the big supply stores and they sent it to me right away. It has a metal frame very sturdy and very well constructed which it will last me for a whole year with only required wash every month!

BOTTOM LINE: Yes, I recommend this product

Washable filter

Comments:

I ordered the incorrect size. Discount filters provided me with a prepaid return label. They were unable to apply the credit back to my card because it was replaced with a new card. I am waiting for a refund check. Their service is top notch and products are well made. I am also using a refrigerator water filter from Discount filters and it is working great.

BOTTOM LINE: Yes, I recommend this product

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
