Good Afternoon Friend, that's a great question!

Typically the FILTER RESET light will illuminate after 250 hours of operation. To locate the filter, remove the bucket and the pull filter downwards. The filter can be clean by using clean water or vacuum cleaner extension hose. If you use clean water, please allow the filter to dry. Once you reinstalled the filter then replace the bucket. To extinguish the light simply press the FILTER button and your dehumidifier should resume normal operations. Remember it is best to clean your filter every two weeks based on normal operating conditions. Hope this helps! - Z

To find and remove the filer. First, turn the unit OFF & unplug it. Then remove the water bucket. The filter frame & handle will be located at the top of the bucket holder just behind the front louvers. If you have never removed and cleaned the filter, it may have a piece of plastic tape on it, which was used for shipping. Remove the tape & discard it. Pull the filter frame's tab handle straight down and remove the filter. It can either be vacuumed or if it's really dirty, washed in warm water and a mild dish washing liquid. Rinse thoroughly and shake off any access water. Allow it to dry completely, before reinstalling it. Never operate the unit without the filter in place. Doing so could cause damage to the unit.

Clean the filter at least once every two weeks.

Hope this helped you and thanks for choosing FixYa.

If you haven't already, clean the filter after it has thawed. In addition, the coils behind the filter may need cleaning.

Turn the unit OFF & Unplug it. Remove the filter and the upper half of the front of the cabinet. Clean the cools with warm water and dish washing liquid. Rinse with a damp sponge, dry the coils and apply a light coating of WD40. Reassemble the cabinet, plug the unit in, turn it back ON and take it for a test drive. Be sure to clean the filter at least once every 2 weeks.

How often does the unit run? Does the fan run when the unit is suppose to be running(as the fan pulls the air thru the filter). If every thing operates correctly and the filter is in the right location on the unit then all I can say is that you keep a clean house. Personally I only need to clean the air filter on my dehumidifier about once a summer. I wouldn't be overly concerned if it isn't getting very dirty.

You can wash the filter with water, no problem. However, I would recommend replacing the filter every 3 to 4 months depending on how much you use the dehumidifier. The exposure to constant moisture will cause the filter to grow mold over time.
