Run Your Air Purifier Continuously

Modern air purifiers are made to be run at all hours of the day, so do not hesitate to use yours continuously. This will drastically lessen the amount of time it takes to purify the air in a home. We would recommend running an air purifier at a low setting if you are using it 24 hours a day, as doing so with a high setting could wear down some of the internal components.

Maintain the Purifier and the Filters

You should perform regular maintenance and cleaning tasks on your air purifier and its integrated air filters. When it comes to air filters, HEPA filters should be disposed of and replaced once every six months to a year. Other kinds of filters, including electrostatic filters, should be thoroughly cleaned every month. The exterior of the air purifier should also be cleaned around once a month. We recommend using a microfiber cloth for this task.
