Air filtration with an electronic air filter is one of the most efficient and convenient methods available for improving your home’s air quality. To do their job, these air cleaners need only basic maintenance. That primarily means keeping the pre-filter and collector plates free from the dust and pollen we see a lot of in North Texas.
Your owner’s manual should tell you how often to clean your filtration system. Typically, your system will need cleaning every three months. Always check your owner’s manual before choosing a cleaning method, since these systems can vary substantially.
Using a garden hose – For a quick, simple way to clean your pre-filter and collector plates, take them outside and spray them down with a garden hose. Use light water pressure to avoid damaging the collector plates. Vacuuming the pre-filter is another way to keep it clean so it continues to provide good air filtration.
In a tub – On some air cleaner models, the collector plates can be washed in a bathtub, laundry tub or other large container. Place the plates in the container and add enough very hot water to cover the plates. Then add 3/4 cup automatic dishwasher detergent per plate. Agitate the water to dissolve the detergent and let the plates soak for 15 to 20 minutes. To rinse the plates, soak them in pure water for another five to 15 minutes. Remove the plates to drain. If the draining water looks or feels soapy, rinse the plates again.
In the dishwasher – Use this method for the collector plates only (not the pre-filter) and only if your air filtration equipment’s owner’s manual recommends it. Place the collector plates in the dishwasher. Run the dishwasher as usual, but stop it before the drying cycle and remove the plates. If the plates go through the drying cycle, any remaining debris may become baked on.
Let the pre-filter and collector plates dry thoroughly before you replace them.
Our goal is to help educate our customers in North Texas about energy and home comfort issues (specific to HVAC systems).
