The GermGuardian FLT4825SM is a replacement HEPA filter for GermGuardian air purifiers that take the Filter B size. It is the Smoke Clear version, built to target cigarette and e-cigarette smoke and odors: GermGuardian claims it removes smoke chemicals more than three times as effectively as the standard HEPA Filter B, and it captures 99.97% of particles down to 0.1 micron, including wildfire smoke. An activated carbon layer handles cooking, pet and smoke odors. It suits households with smokers, vapers, open kitchens or wildfire-season air, and it costs more than the plain HEPA Filter B, so buyers without a smoke problem get little extra from it.
