Steps to Clean Filter

There are different steps to clean your air purifier filter.

Check manufacturer instructions

Air filter systems are used to make sure that the air quality inside a building is healthy. However, when setting them up, it is possible for the instructions provided with each air filter system not to be clear enough.

Check manufacturer instructions first, before buying the filters and installing them into your HVAC system. Firstly you need to pull impure air at pre-filter, then a carbon filter, and finally a HEPA filter.

Open up your air filter

Almost all air filter covers have tabs that make them easy to open and close/remove. This is the present backside of the filter and will require you to loosen it via hand before you can pull it off. Air filters require screws to remove, so if your specific model doesn’t open easily with a tab then you may need some use of a screwdriver.

If you are unable to open the air filter cover from your device, simply check the manual or perform an online search for specific instructions on how to take off this type of filter, or also ask for help on any forums to which you subscribe.

Remove your old filter

An air filter is a fantastic thing to have in your home but can be quite messy if you’re not careful. After removing the old filters and disposing of them, be sure to place the dust into a bag so that clean air can continue to circulate freely in and out of your house.

Fix New Air Filter Cover

Some air filters require that their cover be replaced after they have been installed. After you have completed your installation, replace the filter cover.

Be sure to secure the screws with their respective guide holes in order for the filter to operate properly.

Use Vacuum Cleaner for Non-washable Filters

  • Remove the filter from your air purifier. Many air purifiers use non-washable HEPA filters, which means they can last anywhere between 8 and 12 months.
  • Turn off and unplug your appliance before accessing the filter. Check your product manual for specific instructions on how to access your appliance’s filter.
