Aren’t all HEPA filters pretty much the same?
• Absolutely not. In many units, HEPA media filters are constructed with inexpensive particleboard frames that can warp, crack, off-gas and support microbial growth. In many instances, completed filters are not tested in accordance with Institute of Environmental Sciences and Technology IEST-RP-CC001.3 and MIL-STD 282. Damage to the media pack or leakage between the media pack and the filter frame that might compromise overall efficiency can therefore go undetected. The true Type C (99.99% efficiency @ 0.3 microns) gel seal HEPA-CARE filters are constructed with extruded anodized aluminum frames, have a UL900 Class I flammability rating, and meet IEST and MIL standards, including 100% testing. The unique silicone gel seal provides a more secure, bypass-free seal than other designs.
