How to clean your MWR filter:
1) Immerse the filter in MWR filter cleaner for 30 minutes
2) Wash the filter in warm water with detergent
3) Rinse the filter with clean water until all soap is removed from the filter
4) Let the filter dry
5) When the filter is completely dry, coat the filter with oil on both sides and gently massage the oil into the foam, making sure there is no dry spot left.
