PRODUCT FEATURES
Clarifi™ Reverse Osmosis uses high pressure to push water through the system’s four-layer reverse osmosis filter, in addition to the pre-filter and carbon filter, to remove 90+ contaminants from your drinking water. Designed for easy DIY maintenance, the carbon and RO filters and optional remineralizer cartridge have a two-year lifespan so you can quickly and easily replace them at the same time, and it takes less than a minute to replace each filter. You can install with confidence, knowing the Delta® Clarifi™ Tankless Reverse Osmosis System is backed by our warranty and highly-trained, live customer support.
