In less than two minutes, you can ensure that the air you breathe is clean, reduce household dust and prolong the life of your furnace. Plus, by replacing your air filter, you’ll be ahead of the game – only one in five Americans pays attention to their furnace filters!
Note: Before choosing a cleaning method, it’s a good idea to read specific instructions on how to care for your electronic air filter in your owner’s manual.
Tub. Fill a bathtub with hot water (but not boiling, you don’t want to hurt your hands). Pour ¾ cup of mild dish soap in the water and then submerge the air filter. Let it sit for 15-20 minutes. Remove the filter and let it dry completely before putting it back into the furnace.
Dishwasher. Before you place your filter in the dishwasher, set four glasses upside-down on the bottom rack to rest the filter on top of. This will protect the filter from the dishwasher spikes during the cycle. Only run the filter through a wash cycle – never run it through a dry cycle! This will just “bake” any remaining residue onto the filter. Remove the filter and let it dry completely before putting it back into the furnace.
Garden hose. Wet your filter with your garden hose, and apply mild dish soap to the filter. Then, using a spray nozzle on your garden hose, spray the dish soap away. Let the filter dry completely before putting it back into the furnace. Tip: If your filter is really dirty, you may want to put extra effort into evenly spreading the soap. To do this, fill a plastic bottle with a mixture of ½ warm water and ½ mild dish soap. Spray the filter, and then rinse the soap away with your garden hose.
