This Philips Integrated 3-in-1 NanoProtect Replacement Filter FY2180/30 is a cylindrical 3-in-1 filter that combines 3 filtration layers to maintain the performance of your device. The best combination to eliminate pollutants, viruses, allergies, and bacteria is our Active Carbon, HEPA, and pre-filter. We advise changing all three filters at once to ensure that you are breathing cleaner air. A built-in 3-in-1 filter offers constant defence and ensures ideal filtration for up to 36 months. The pre-filter should be routinely vacuumed cleaned for the best filtration performance.-White and Black-Size (23.8x23.6x29.8)
