3M Aqua-Pure AP-DWS1000 Drinking Water System

The system includes a built-in meter that tracks the volume of water passing through the filter. Once the filter reaches its 625-gallon capacity, the meter automatically stops the water flow, ensuring you never accidentally drink water from an exhausted filter.

The AP-DWS1000 is designed for straightforward installation. It uses 1/4-inch quick-connect fittings, which typically require basic household tools, though you should ensure you have adequate clearance under your sink based on the 15-3/4 inch height requirement.

This dual-stage system is rated at 0.5 microns, which is effective at reducing lead, volatile organic compounds (VOCs), chlorine taste and odor, and cysts like Cryptosporidium and Giardia.

It is designed to be clean and simple. The sanitary cartridge design allows you to twist the old filter off and snap the new one into place without needing tools or dealing with messy water spills.

The system has a flow rate of 0.6 gallons per minute. While this is sufficient for filling glasses or pitchers, it is slower than a standard kitchen faucet, so it is best used as a dedicated drinking water tap rather than for filling large pots for cooking.

No, the 3M AP-DWS1000 is a mechanical system that relies entirely on your home's water pressure. The automatic shut-off meter is also mechanical, so no electrical connections or batteries are required.
