Only use the appliance to filter water that meets drinking water 

standards at the point of use.

Do not block the filtered water outlet or connect other devices to it.

If the water pressure is very high, reduce the water flow of the tap to 

prevent damage to the cartridge.

Keep the water purifier away from heat to avoid distortion or 

breakage.

Do not tamper with the water purifier.

Do not remove the filter cartridge while you use water purifier.

Do not use the water purifier without a filter cartridge.

Do not place the appliance near a window where it is exposed to 

direct sunlight.

This appliance does not soften water.

Do not use filtered water in aquariums. Tap water, filtered or 

unfiltered, can be harmful to fish.

Do not store purified water to avoid contamination. Air contact 

contaminates purified water quickly. If you want to store purified 

water, use a clean container and keep it in the refrigerator. Do not 

keep it in the refrigerator longer than 1 day to avoid contamination.

Philips’ multi-filtration system consists of a primary filter, a secondary 

filter, a high-tech hollow-fibre membrane filter and a granular 

activated carbon filter.

The hollow fibre membrane contains more than 520 billion 

micropores that are small enough to remove particles down to 

0.1µm. It eliminates 99.99%* of bacteria, rust and other particles 

larger than the micropore size from your tap water without removing 

calcium, magnesium and other minerals that are vital to your body.  

(* tested according to Japanese Water Purifier Association (JWPA) 

standard).
