360 Infinity Tankless RO
Space-saving tankless design with no under-sink storage tank, and just two filters to replace. Prefilters last about a year and the membrane about two, all backed by a 3-year warranty.
SKU 360-INF-RO
Why the Infinity
No storage tank
Makes water on demand with no under-sink storage tank, freeing up almost the entire cabinet.
Only two filters
A 3-in-1 composite filter and a long-life RO membrane are the entire maintenance list.
Twist-lock filter changes
Twist the cartridge a quarter turn and pull it out. Under a minute per filter, no tools.
TDS-metered faucet
A live total-dissolved-solids readout shows exactly how clean the water in your glass is.
Two waters, one faucet
Flip the handle for filtered water to cook and rinse, or purified RO water to drink.
Automatic flushing
The system flushes itself on a set schedule to help keep the membrane performing.
Overview
About this system
Purified drinking water the moment you ask for it, with no storage tank under the sink and only two filters to ever replace.
A tank-style reverse osmosis system stores water it made hours ago. The 360 Infinity Tankless RO makes water the instant the faucet opens, flushes itself automatically, and shows on the front display when a filter is due.
The two-filter design
Stage 1, PCT Composite Filter (3-in-1). PP sediment, carbon fiber, and post carbon block in a single twist-lock cartridge. Removes sediment, residual chlorine, and off tastes and odors. Replacement cycle 8 to 12 months.
Stage 2, RO Membrane. Reduces total dissolved solids and the dissolved contaminants carbon cannot catch. Replacement cycle 12 to 24 months.
Both filters change with the water supply still on, so a filter swap needs no shut-off and no tools.
One faucet, three positions
- Filtered. PCT filter only, for cooking, washing produce, and filling the kettle. The RO membrane stays out of the loop, so it lasts longer.
- Purified. PCT filter plus RO membrane, the purest water the system makes, and the mode that puts a live TDS value on the display.
- Off. Handle centered. The faucet is closed and the system sits idle until the next draw.
Smart display and automatic care
- Purified TDS readout, a live mg per L value refreshed every ten seconds.
- RO and PCT life bars, a per-filter bar graph that flashes and alerts when a change is due.
- Automatic flushing, 18 seconds at power-up, after 30 minutes of continuous use, and again after 6 hours.
- Quick-connect ports for inlet, purified, filtered, and drain, push-to-fit with lock clips.
What it reduces
Sediment, sand, rust, and suspended material. Residual chlorine. Unpleasant flavor and odor. Total dissolved solids. Arsenic, lead, chromium, and mercury. Sodium, nitrates, and other heavy metals.

90 percent TDS rejection tested under standard laboratory conditions after full flushing. Actual performance varies with source water quality, usage, and water pressure. Longer RO filter life assumes Purified mode is reserved for drinking water. Do not connect this system to a hot water supply line. Well water must pass through a pre-filtration system before the unit.
