The Philips Air Purifier’s multi-layer filtration system is one reason why it’s so effective. First, a pre-filter removes large particles, then an active carbon filter removes potentially harmful gases such as TVOC, smoke and odours. Finally, a HEPA filter removes ultrafine particles as small as 0.003um, including allergens, dust and dust mites.* The result is a superior filtration system that provides cleaner air.
