Philips reusable replacement filters help clean the air you breathe by capturing dust, pollen, mold spores, pet dander and more with an 88% efficiency at 7-10 micron. The reusable filter must be in place at all times when the device is operating.
Usage: These filters are reusable and should be cleaned after 2 weeks of use or sooner if they appear dirty. They should be replaced every 6 months or sooner if they appear damaged.
The white filter material is permanently attached to the gray plastic filter housing. They are not designed to be detached from one another.
