This filter reduces unpleasant smells such as smoke, cooking or pet odors. It's replacement schedule is once a year. 

Winix Washable AOC Carbon Filter

The AOC Carbon filter should be washed every three or four months but should be replaced once a year. When it becomes dirty, you should rinse it lightly under running water and let it dry for 24 hours.

While some issues may be too complicated for you to tackle, there are simpler ones that you can troubleshoot. The following are some tips to help you solve minor problems in your air purifier:

Too many obstructions around your air purifier can impede the proper flow of air. The area around the gadget should be clear. 

Push Or Touch Buttons Do Not Respond
