The 3M AP903 water filter system is installed on the main water supply and filters water before it reaches taps, showers and household appliances. The AP917HD replacement filter combines pleated nonwoven media and activated carbon to reduce sediment, rust and dirt, as well as chlorine taste and odour. It is suitable for mains or well water, for residential and light commercial use.

The filter is replaced with a quarter-turn, without a wrench or contact with the filtration media. Replacement is recommended every 12 months at most, or sooner if water pressure decreases or the water’s taste and odour change.
