Light Commercial 150 GPD Reverse Osmosis Water Filter System

Most under-sink RO units slow to a trickle when a big family or a busy lunch rush demands more water. The Light Commercial 150 GPD reverse osmosis system is built for exactly that gap: fast enough to run tankless for a household, and expandable with a storage tank for light commercial use — one system that grows with your demand instead of being replaced by it.

5-Stage Reverse Osmosis Filtration: What It Removes

Water passes through five purification stages: a sediment pre-filter catches rust, sand, and silt; two carbon filters strip chlorine, chloramines, THMs, and the tastes and odors that come with them; the semipermeable RO membrane rejects dissolved solids down to 0.0001 microns; and a post-carbon filter polishes the water just before your glass.

Together they reduce up to 99% of over 1,000 pollutants, including:

• Heavy metals — lead, arsenic, chromium, mercury
• Forever chemicals — PFOA and PFOS (PFAS)
• Chemicals and disinfection byproducts — chlorine, fluoride, pesticides, sulfur, THMs
• Pathogens — bacteria, viruses, and cysts too small for standard filters

The result: low-TDS, clean-tasting water for drinking, coffee, ice, and cooking.

Booster Pump and Pressure Gauge Do the Heavy Lifting

Reverse osmosis lives and dies by water pressure. The integrated booster pump raises incoming pressure to the membrane’s optimal operating level, which means faster production, less wastewater, and consistent output even in homes or buildings with weak municipal pressure.

The front-mounted pressure gauge makes maintenance obvious instead of guesswork: when the needle starts dropping, your pre-filters are clogging and it’s time for a filter replacement — before water quality or flow ever suffers.

Tankless Speed, Light Commercial Capacity

At up to 150 gallons per day, this unit produces purified water fast enough to work as a tankless system — no bulky pressure tank under the sink, no stale stored water, just fresh RO water on demand. Need more? It scales:

• Large families: run it tankless for unlimited fresh drinking water
• Restaurants and cafes: add a storage tank for continuous, stable supply during peak hours — ideal for espresso machines, ice makers, and prep sinks
• Offices and small businesses: feed a water dispenser or break-room tap with steady purified water all day

If your business also needs high-flow sediment and chlorine protection for the whole building, pair this unit with one of our Big Blue filter systems — installing one upstream extends the life of your RO pre-filters too.
