We as humans throw a lot of stuff in the garbage every year. However, it is in your best interest to buy something that is reusable again and again. Take the air filter in your car. It is recommended that you change that out every 15,000 to 20,000 miles. That is a lot of added waste going into our landfills.

K&N washable and reusable replacement air filters are designed to be washed and reused instead of thrown away. This not only keeps millions of air filters out of landfills annually, it saves you money as well.

Our filtration media is made from oiled cotton media that is not only durable but is a renewable resource. This cotton is then layered between aluminum mesh for rigidity and longevity. We are so sure of the quality of our air filters that we affix a 10-Year/Million Mile Limited Warranty to them so you will never have to replace that filter again.

Save Money and Help the Planet

Money Filter

K&N replacement air filters are designed to replace the air filter in your vehicle with one that is washable and reusable. At an average cost of approximately $15, that would be $150 in ten years, if you change your filter annually, or more if you pay someone to do it.

That doesn’t sound terrible until you realize that one K&N air filter, at a cost of around $50 will last at least 10 years and probably a lot longer than that. In ten years, you could have saved yourself $100 or more. On top of that, you only need to clean your filter every 50,000 miles, depending on your driving conditions, which will in turn save you time and frustration.


We said it before, but it bears repeating. Our air filters come with a 10-Year/Million Mile Limited Warranty. That means that if you ever have an issue with your filter, we will replace it for you, for 10 years or a million miles. If that doesn’t say something about our confidence in our products, we’re not sure what would.

This confidence comes from our 50 years of industry leading research and development and stringent quality assurance that our filters must pass before they are shipped to you. Only high quality cotton, aluminum, oil, and rubber are used to make the filters that you choose to protect the vital internals of your engine.
