I buy an air filter on Amazon and I can say that I am satisfied with both the price and quality and fast delivery. I realized that it's very important to change the filter on time because if it's damaged or dirty, it consumes too much fuel. By the way, one of my last purchases from Amazon was an ozone generator. I didn't think it was such a useful thing. I have a St. Bernard dog and I can say that when we take him with us on trips, our car doesn't smell fresh. So I decided to order a device for air purification. Moreover, the ozone generator kills germs, and this's very useful as additional protection against coronavirus.
