Troo Air Purifier Filter Set (True HEPA Filter FY-2422 + Activated Carbon Filter FY-2420) Compatible with Philips Air Purifier Series 2000, Models: AC-2887, AC-2882, AC-2892, AC-3821

Very good and effective. Brought down the aqi from 369 to39 and oscillating in a closed 12x10" room within less rgan hour

Size fit issue. Though the filters are of same size but the outer foam is too thin. It causes fit issue. The over all fit is loose.

Fits Philips 2887/20 model well.Its both Activated charcoal+ HEPA filter combo.Price seems good for looks but not sure if it's a true HEPA 3 micron or 2.5 micron.Musty smell from AC reduced significantly during first day of use. Remains to be seen how long it works in enclosed room.

I found it better than the original in terms of weight and built quality. It's a complete value for money product

It’s a poor product anf got choked after few days only
