The Philips AUT821/97 CP compound filter cartridge uses a 2-in-1 activated carbon and PP cotton structure, handling both coarse filtration and adsorption in a single cartridge. It effectively reduces sediment and other large suspended particles, rust, residual chlorine and off-colour and odour, improving the clarity and taste of everyday drinking water. It delivers up to 3,650 litres of filtered water with a service life of up to 1 year, and is designed for the Philips AUT7005 under-sink water purifier.

Combines activated carbon and PP cotton in a single cartridge, completing coarse filtration of large particles together with adsorption of residual chlorine and odour for more thorough filtration.
