How do I determine what air purifier I need based on my room size? Small rooms, often below 100 sq. ft. may only require a tabletop or mini tower-style air purifier to circulate the air. Medium rooms that range between 100 sq. ft. and 170 sq. ft. will typically need a floor model that has a larger filter to effectively process the air in the room. Large rooms, over 170 sq. ft. will require a full size tower or box style unit. Most air purifier cartons and descriptions offer specific information on room size or square footage covered by the air purifier.
What is HEPA? HEPA stands for “High Efficiency Particulate Air.” A HEPA filter must capture 99.97% of all particles that pass through it that are 0.3 microns or greater in size. HEPA is composed of a layer of randomly arranged fibers. HEPA filters are often used in airlines, vacuum cleaners, cars, etc.
What is CADR? CADR stands for “Clean Air Delivery Rate” which indicates the volume of filtered air delivered by an air purifier. CADR ratings show the effectiveness of how efficient the air purifier is at capturing fine particles, such as: tobacco smoke, dust, and plant pollens.

Where should I place my air purifier? You can place your air purifier in a room in your home or office, slightly placed away from the wall and any furniture. Depending on the model, it can be placed on the ground or on a table. We recommend placing it in a room that you are using often, or have the most odor, dust, pollen, or pets. Can I leave my air purifier on at all times?Yes, we recommend running your air purifier 24/7, depending on the season, or your needs.
How often do I need to replace my filter? GermGuardian® air purifier filters should be replaced every 6–8 months depending on use. You can always vacuum off your carbon filter layer in order to extend the life of your filter.
How do I replace the filter? Please refer to your product instruction manual. A downloadable version of the manual for your specific air purifier is available under product specifications, or under the support tab.
How do I know I need to replace my filter? You will know your filter needs to be replaced when the filter turns from white to gray or black.
What is a carbon filter? Carbon filters are also called charcoal or activated charcoal/carbon filters. It is a form of carbon that is extremely porous making it excellent at absorbing. Carbon filters can absorb a variety of chemicals and vapors simultaneously.
What is an ionizer? Ionizers can be combined with filters to emit a small charge to the airstream that causes particles to stick to the filter with an attraction similar to a magnet.
Is my filter washable? The pre/charcoal filter layer that attaches to the HEPA portion of the filter can be cleaned using the brush attachment tool on your vacuum cleaner. Once the HEPA portion of the filter turns from white to gray or black, the filter must be replaced entirely.
