Cleaning a washable filter

If the amount of dirt on the filter is minimal, use a vacuum or compressed air to remove it. If you use
compressed air, the air must move through the filter in the opposite direction of the air flow indicator
on the side of the filter.
Caution! If not avoided, the following could result in minor or moderate injury.
• Install dry filters only. Wet or damp filters can cause an electrical short and damage the product.
1. Hold the filter on an angle under warm running water so the water flows through the filter in
the opposite direction of the air flow indicator on the side of the filter.
2. Rinse the filter thoroughly.
3. Submerge the filter for a minimum of 30 minutes in a container of warm water and two
tablespoons of mild detergent or liquid dish soap.
If the filter is extremely dirty, move the filter from side-to-side occasionally or remove the
excess dirt by brushing both sides of the filter with a soft brush.
4. Rinse the filter thoroughly by holding it on an angle under cool running water.
The air flow arrow on the side of the filter should face down.
5. If the filter still appears dirty, repeat steps 3 and 4.
6. Shake the filter over a container until most of the water is removed.
