How to Clean Vacuum Cleaner Filters. Something that many people overlook when using a vacuum cleaner is making sure the filters are clean. If your filters aren't clean you won't get much suction from your vacuum cleaner and your vacuum cleaner won't pick up the dirt. Luckily, you can clean your vacuum cleaner filters.
Check your owner's manual. Each vacuum cleaner has specific ways to clean the filters. Some have detachable parts you can rinse in a sink; others simply need any dust brushed out of the filter. If you don't have your owner's manual, go to the website of your vacuum cleaner's manufacture. Chances are they have instructions for cleaning the specific filters for your vacuum cleaner.
Tap the filter against a garbage can. However, be careful about this since you can send the dust particles you just vacuumed back up into the air or onto the ground.
Brush the filter using a soft brush such as a toothbrush. Make sure you do this over a garbage can to catch all the dust.
Using an air compressor, blow air backwards through the filter to get the dust particles off.
Rinse your filter under running water if your filter can handle this. Do not use running water on your filter unless your owner's manual suggests it.
Replace your filter every six to 12 months depending on what your owner's manual says.
Plan on cleaning your filters every second or third time you use the vacuum cleaner to prevent dust from getting into the motor and keep your vacuum cleaner's suction high.
