Cleaning

Use a vacuum cleaner to remove light dust. If there is sticky dust on the filter, wash the filter in lukewarm, soapy water, rinse it in clean water, and dry it.

How to replace the anti-mold filter

Insert the top of the anti-mold filter, and then fit the protrusions on the bottom of the filter all the way into the hooks on the unit. Press the locations marked by the arrows and close the front panel.

Air Clean Filter

The air clean filter removes dust and dirt from the air, and reduces odors and smoke from tobacco.

This air clean filter cannot remove harmful gases or vapors nor ventilate air in the room. You must open doors or windows frequently when you use gas or oil heating appliances. Otherwise there is a risk of suffocation in extreme cases.
