How do I determine what air purifier I need based on my room size?
- Small rooms below 100 SF may only require a tabletop or mini tower-style air purifier to circulate the air
- Medium rooms that range between 100 SF and 170 SF will typically need a floor model that has a larger filter to effectively process the air in the room.
- Large rooms over 170 SF will require a full size tower or box style unit.
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.
How often do I need to replace my filter?
GermGuardian® air purifier filters should be replaced every 6–8 months depending on use.
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 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 and plant pollens.
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.
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.
