Philips 3-in-1 filter, NanoProtect HEPA, Active Carbon and Pre-filter

3-in-1 cylindrical filter includes a pre-filter, Activated Carbon filter, and NanoProtect HEPA filter, working together from the start to capture pollutants, allergens, pollen, bacteria, and viruses. All three layers are replaced simultaneously for convenience.

Eliminates up to 99.9% of viruses and airborne aerosols, including those potentially carrying respiratory viruses — independently tested for effectiveness.

NanoProtect HEPA technology uses electrostatic charge to attract and trap airborne particles more efficiently and purify faster than standard medical-grade HEPA H13 filters.
