Advanced HEPA+ Replacement Pre-Filter
The genuine Advanced HEPA+ Replacement Pre-Filter for the Advanced HEPA+ Air Purifier is the large particle pre-filter that helps to prolong the life of the inner filters, especially the HEPA filter. The pre-filter can be seen through the sides of the purifier. Long-life Advanced HEPA+ pre-filter traps large-sized particles that can easily be seen with the eye during the first stage of a 4-stage filtration process. In performing this role, the pre-filter helps to prolong the life of the inner filters, especially the HEPA filter.
Clean the pre-filter when dirty, simply vacuum the outside grille of the air purifier with the brush attachment of your vacuum on a monthly basis to reduce surface build-up and prolong the life of the pre-filter.
The pre-filter can last for years with regular cleaning, although replacing annually is an option for the cleanest air. Either way, this pre-filter avoids regular filter changes often required with other air purifiers, for cost savings and long-term value.
Package contains one (1) Pre-Filter. Choose from Standard or Junior size pre-filter, available in black or white, to fit your Advanced HEPA+ Air Purifier.
