The Philips WP4141 is an under-sink water purifier that installs neatly beneath the kitchen sink. Its AquaShield multi-stage filtration pairs a CBPA antibacterial activated-carbon composite cartridge (model WP3976) with a UF hollow-fibre ultrafiltration cartridge (model WP3985) to remove up to 99.9% of bacteria and parasites, along with dissolved lead, heavy metals, volatile organic compounds, pesticides, chlorine and unpleasant tastes and odours, delivering clean drinking water on demand.

The CBPA and UF cartridges work together to remove up to 99.9% of bacteria and parasites, plus dissolved lead, heavy metals, VOCs, pesticides, chlorine and odours.
