K%26N makes an excellent air HVAC filter. They have many years of experience behind them in the automotive industry. Filters are very easy to clean and or backed by a lifetime warranty. They also make a cleaning spray to make cleaning fast and easy.

So far so good.

I haven't had to clean my filter yet but it is working well after a month of very cold weather. This filter seems to let more air pass through vs the expensive disposable filters I used to use. With the better airflow I haven't noticed any more dust than with the disposables either so so far so good.
