How Often Should You Clean The Levoit Air Purifier Filter?

Knowing how often to clean Levoit air purifiers can be tricky. For example,  how often you use your air purifier and the quality of your home can play a role. And some people never think to clean their air purifier until the “Replace Filter” light turns on. As a rule of thumb, we recommend cleaning your air purifier once or twice a month for prolonged use.

It can be hard to answer how long Levoit air purifiers last as it depends on a variety of factors. Some of these factors include how often you run your air purifier, the quality of the air in your area, and how often you clean and maintain your model.

How To Tell That The Levoit Air Purifier Filter Is Dirty?

It is all well and good having a rough cleaning schedule, but how do you know when to clean your air purifier filter? Most Levoit models come with an indicator that tells you to either replace or clean the filter, depending on the type. However, if you do not have an indicator, here are some things to consider when trying to work it out:

  • Your air quality has not improved even when the purifier is on regularly
  • It has been a while since you cleaned or replaced the filter
  • Your air purifier is particularly warm
  • Your air purifier makes odd noises during use

If you are unsure, the best way to know is to remove the filter and look at it yourself. Remember to put cleaning or replacement reminders in your phone or home calendar to ensure you remember every time.
