What is 3-in-1 Filtration?

The air purifier uses a three-stage filter to remove airborne pollutants from indoor air.
STAGE 1: Pre-filter to remove large dust and particles
STAGE 2: High-efficiency filter to remove over 99% of particles sized 0.3 microns (models RMAP-ST, RMAP-XL) or 99.97% of particles sized 0.3 microns (models RMAP-SST, RMAP-SXL)
STAGE 3: Activated carbon filter to remove odors from the air before returning to the room

How often should I change my filter?

We recommend replacing the filter every 6-12 months, or when the filter replacement icon appears on the unit's display. Replacement time may vary depending on the number of hours used and/or the environment in which the air purifier is used. If the filter replacement icon does not come on after 12 months, we recommend changing the filter at that time.

How do I clean the pre-filter?

Between filter replacements, you can clean the pre-filter with a vacuum cleaner or a soft brush. Do not wash.

How do I order a new replacement air purifier filter?

For all air purifiers (RMAP-ST, RMAP-XL, RMAP-SST, RMAP-SXL) you can purchase replacement air purifier filters from our replacement filters product page.

Are the included casters required to be installed on the air purifier?

Installing the included casters is optional. However, many owners will enjoy the convenience of rolling the air purifier from room-to-room once the casters are installed.
