How to Replace a Honda HEPA Air Filter By Thomas West, eHow Contributor The initials in the acronym HEPA stand for High Efficiency Particle Arrestor. The first HEPA filters were originally used in hospital operating rooms because of their sub-micron filtration ability. HEPA filters, also known as a cabin air filter, have been installed in Honda automobiles since 2003. A HEPA cabin air filter will purify the indoor air of the Honda's cabin by greatly reducing or stopping small particles from entering the cabin while the windows are closed. Instructions 1. Open the glove box door on your Honda's dashboard and temporarily remove all contents from the glove box. Remove the stop on the right side of the glove box by unlatching it from the glove box door. 2. Push in on both sides of the glove box at the top while pulling the top of the glove box out of the opening. This will release the glove box from the dashboard and allow it to hang out of the way. 3. Look into the opening left by the glove box to locate the HEPA cabin air filter. The cabin air filter housing should be visible inside the dashboard. Pull out the air filter housing by pressing in on the tabs on each side of the filter housing. Remove the soiled air filter. Compare the old filter with the replacement filter before discarding it. 4. Wipe out the filter housing with a clean damp cloth . Place the new filter into the filter housing. Make sure you place the new filter right side up by checking the air flow direction indicator on the filter. Slide the housing back into the dashboard until it snaps into place. 5. Lift up on the glove box and gently push it back into position until it snaps into place. Reconnect the glove box door stop and close the glove box door.
