Are air filters reusable?
Some specially made air filters are cleanable. Most cleanable filters are the older, wire-fame style. They can be washed with automatic dishwasher soap and air-dried. It is not recommended to blow out any air filter with an air hose. By using high-pressure air, you may enlarge the holes in the porous paper or cause a hole. However, in most cases, air filters are so inexpensive, it is usually recommended to check them a minimum of twice a year and change when dirty. If you use the vehicle off-road or in a particularly dusty area, you may need to change it more often.
