How Do Air Filters Work?
Air filters remove airborne and particulate matter such as dirt, allergens, bacteria, dust and smoke from the air. Air filters work by pulling air through a filter and trapping the particulate matter.
Why use Genuine GermGuardian Filter Replacements?
Your purifier is only as powerful and effective as the filter you put inside, and our Genuine GermGuardian replacement parts are essential for maintaining product performance. Each filter or bulb is designed specifically for a particular unit style. Not only will genuine replacement parts fit like a glove, but they also have the combination technology to match so that you can get the most out of your air purifier or air sanitizer.
How Often Should I Replace My GermGuardian Filter?
We recommend you change your combination filter (HEPA Filter + Carbon Pre-filter) every 6–8 months. Like other consumables, lifespan of a filter is based upon usage. Our air purifiers are built for constant daily use. If you use yours less frequently, your filter will last longer. You can usually determine whether you're ready to change the filter based upon its appearance. If your pre-filter appears dirty, you can replace the carbon pre-filters, this will help extend the life of your HEPA filter. If your HEPA filter appears dirty, it is recommended to change the combination filter.
How do I reset the filter indicator light after replacing the filter?
Resetting the blinking light after replacing your filter requires a manual reset and differs per air purifier. Please locate your manual and follow the instructions. If you do not have your manual, you can locate it on Guardian Technologies website.
