We have plenty of dust here in Arizona. The air filters I have been buying do not last very long. I thought using your product would be less expensive in the long run. I have not had it long enough to see how it works.

I bought this air filter from my work yesterday. I drive a 2000 Toyota 4runner 3.4. Of course everyone knows that vehicle drinks gas like crazy. Especially being 15 years old. It got to the point where I was spending $120 a week on gas. So I used seafoam cleaner and bought the air filter. The price got me but as soon as I put it in and drove it for a bit I instantly noticed a difference. From feeling the gas sucking horribly while stepping on the gas pedal with my old filter to actually feeling the difference with the K&N air filter was astonishing. After driving to work and back usually I'd kill almost a quarter tank. But since I put the filter in I can tell that my intake air system is breathing a lot better and the needle barely dropped. Highly recommend this air filter. Pricey but you really do get what you pay for. Extremely satisfied.
