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

K&N Filters (in my opinion) are the Best, and this K&N Cleaner works EXACTLY AS EXPECTED on my HVAC LIFETIME Home Furnace Filter. Works like a charm. This size bottle lasts a long time. Cleans filter perfectly, monthly, without a problem. A++++. Of Course, I HIGHLY RECOMMEND!No unpleasant smell either, when cleaned in the house/bathroom. Great Value!

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.

Great cleaner

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

This is the best cleaner for K&N filters hands down. Does the job very well at cleaning the filter.

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.
