Air filters are not universal, as they come in different sizes, porosity levels, and shapes. This means that you need to know which air filters are suitable for your home, office, or car. Car air filters are model-specific and cannot be used interchangeably. Universal air filters provide an air system with a protective layer that keeps out harmful particles and allows clean, fresh air to flow through.
However, these filters have their limits and will eventually need to be replaced. Universal also manufactures washable pre-filters for HEPA systems and cleanrooms. These filters are designed to extend the life of more expensive, disposable HEPA filters. A human hair measures approximately 50 microns, so air filters are quite advanced.
They are made with papers and synthetic fibers and can remove more than 90% of pollutants from the air. All air filters provide a certain layer of protection to an air system by absorbing and trapping passing particles. MERV, or Minimum Efficiency Report Value, is a rating system that measures a mesh fabric of air filters. The right filter for your car is extremely important, as a poorly adjusted filter will allow unfiltered air to enter the engine, which could cause serious damage.
When an air filter is covered with dirt and debris, the mesh fabric cannot receive the air flow properly. Compressor blades rotate at more than 200,000 rpm and any abrasive grain that passes through the air filter can destroy it. Hitting the replacement filter elements against a hard surface will remove large, loose debris if you have compressed air that will help remove the finer particles. In conclusion, it is important to remember that air filters are not universal and must be chosen according to the specific model of your car or home. Universal air filters provide an effective layer of protection against harmful particles but must be replaced regularly.
