14x20x1 Washable Permanent A/C Furnace Air Filter

My family lives in a tiny, older house where the air vent that needs a filter is located in the floor of the only hallway. On top of every day foot traffic by humans, we have three dogs, and we were going through filters almost every week.I've been making efforts to reduce my family's carbon footprint, and was happy to find these, and when they arrived, I can't tell you how pleased I am that they were so sturdy.It's been 3.5 months, and, again. So thankful for this product.Make sure you buy two.

Works better than I thought it would, better than the basic dust Filtrete Filter. The first month didn't show much, but after the second month that sucker was dirty. Cleaning is easy, but be careful the wire grate is a little sharp. I bought a second one to use while washing my first one.

Been using permanent HVAC filters for 8 years. I take them to the DIY car wash and use the high pressure to clean, then air dry before reinstalling. I have 2 sets.

Bought two and clean and swap one in my furnace every month for months now. A little simple green and some hot water makes them like new again!

Product is very high quality. Due to holiday delay, we could not wait for filter and had to buy it from another seller; the one we bought is not as good as from this seller.

Seem to work

Seems to work well so far. No real indication of static electricity collecting anything in just over a month.

Not what I was expecting but very well made
