K&N HVAC Filter Cleaner: 32 Oz Spray Bottle Filter Cleaner and Refresher; Restores K&N Home Air Filter Performance; 99-6010

It's THE cleaner for THE filter. K&N Home and Auto inside air filters.If it's hot where you are, the product may arrive outside the bottle. Mine arrived with tape on the neck and sealed in a plastic bag in a box. It was hot and it was wet but not emptied.

If you have a K&N washable filter, you need this product. I had washed with water only a few times. This brought out much more dirt and dust than water would. I would recommend wearing a mask while spraying and being in a well ventilated area. Product smell acidic.

Cleaning solution works well to get the trapped dirt out of my furnace filter. Works best when you soak the entire filter and let it sit for 5-10 minutes.

Going to have to find an alternative I really like this stuff but half the bottle is in the plastic wrap they pack it in. Buying 1 at a time you just can’t protect it from spilling. If you bought a case it would be fine but you don’t use it enough 1 bottle last me over a year it’s good stuff

I have been just washing with water and now that they have this spray it clean the filter nicely. I sprayed one of my filters that haven't seen this product in a few washes. This product broke down the dirt so much that the water was darker than usual and the filter color started coming back. I am happy that this bottle of clean was available.

Excellent

use the spray for the home filters

Product works great
