Single Stage Water Filter

The Delta® single stage, high flow, high capacity, under-sink water filtration system filters the chlorine in your bathroom water. With a long-life filter lasting up to 12 months, the single stage water filters reduce impurities that may cause dry skin and hair. The compact design takes up less room under the sink and connects directly to your bathroom faucet's cold water line. For additional bathroom filtration, see Delta® Shower Head Filters.

Frequently Asked Questions

Is the filter system hard to install?

The Clarifi™ single stage system is designed for simple, DIY installation and comes with detailed instructions through the User Guide. However, the difficulty can depend on your DIY skills, tools, and existing plumbing setup. You may need a screwdriver, drill, and teflon tape (for threaded connections). Note that this system can only be installed to a cold-water line.

What do I need to know about replacing the filter cartridges?

We designed the filters to be quick and easy to replace. Remove the old cartridge and install the new one with a simple twist and lock quarter-turn mechanism. The single stage filters will need to be replaced about every 1 year or after it’s filtered 10,000 gallons, whichever comes first. The system will use audible alerts and the LCD digital display to notify you when it’s time to replace the filter. You can order the single stage replacement filter through our website. Other brand filters are not compatible with the Delta system.

Will the High Flow water filtration system work with any faucet?

Yes, the filter can be used with a kitchen, bathroom, bar room, and any other faucet when it's connected to a cold-water line.
