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

Worked just like stated

Furnace filters are expensive so I bought the K&N filters so easy to clean with this spray.

I needed a cleaner and this works like a charm easy to use all I do is just spray it up and then wipe it and it’s clean so for me it does the job

Was delivered on time, but when in transit the bottle leaked and damaged the box. There's still plenty of product left in the bottle, almost full, but would have been fine if it had more packing material in the box with it to keep it from being damaged. Product itself is good and will work for its intended purposes. 4 stars for packaging damage.

The K&N HVAC Filter Cleaner works great! It effectively removes dirt and restores my home air filter’s performance. The 32 oz spray bottle is convenient, and the cleaner dries quickly. My filter looks and functions like new after each use. Highly recommend for maintaining optimal airflow and efficiency. Worth every penny!

Apparently I don't see any dirt on my filter after few months of usage. My first impression was very doubtful whether the filter was working or not. However when I applied the K&N cleaner, the raising water was rather dark. I am now understand the filter and the cleaner must be working together. The filter can trap very little air particles which I cannot clean them by vacuuming.

Works well

I've used K&N filters for years
