Cleaning a Swamp Cooler Filter

A swamp cooler is a useful household cooling device especially if you live in a hot climate area. It is also known as an evaporative cooler. The unit works like an air conditioner to keep your home cool. However, to operate the device, you must ensure that your windows are slightly open. The cooler utilizes an evaporation mechanism to cool indoor air. It blows air over water-saturated pads which act as a wet cell and causes the water to evaporate.

The cool air is distributed indoors and forces warm air out through the windows. Most swamp coolers contain both an air and water filter which enable the air purification process to take place. These filters must be regularly maintained to ensure the unit works efficiently. Below are some guidelines.

Cleaning Schedule

Ideally, you should clean the air filter every 2 to 3 weeks as part of a regular maintenance program. The water filter can be cleaned every 4 to 6 weeks. This will help rid the filters of accumulated dust, dirt, mineral deposits and sediments. Dirt build-up hinders the cooler from optimal performance. However, when you clean the filters regularly, it enhances efficiency and also extends the longevity of your swamp cooler. Always turn off water and power supply before you undertake any maintenance work on the unit. You also need to unplug the cooler to ensure maximum safety while you clean.

Air Filter

This is a screen installed in the cooler to capture dust, pollen and other minute substances from incoming air. It improves the quality of the air indoors and reduces the incidence of allergies. Remove the screws from the rear panel and reach in to remove the air filter. It usually turns grey in color after a couple of months due to the accumulation of dust and dirt. Use warm water and a mild detergent to create a solution of soapy water in a basin or sink. Use a soft brush to thoroughly clean the filter then rinse well with warm water. Allow it to drip dry before you reinstall in the unit.

Water Filter

The water filter is found in the water reservoir of the cooler. Hard water deposits often lead to accumulation of dirt in the filter. Drain all the water from the reservoir. Open the reservoir door and remove the water filter. Fill a sink with some lukewarm water. Add in some mild detergent and mix well to create a soapy solution. Insert the filter in the sink and scrub it all around with a soft brush. This will remove as much of the accumulated sediments and dirt as possible. Allow the dirty water to drain from the sink. It is best to use running water to rinse the water filter as it effectively flushes away the sediments and dirt. Once you’re satisfied that the filter is clean, you can place it on several paper towels or a clean rag to drip dry. You can then reinstall the filter in the unit.
