Solutions, Not Compromises | Home Master TM Undersink Reverse Osmosis Water Filtration System

The Home Master TM Undersink Reverse Osmosis System delivers solutions, not problems. Even the most health conscious individuals will be impressed with its exceptional water quality. This premium drinking water system has been designed to convert your tap water into exceptionally pure drinking water by removing up to 98% dissolved solids, metals, and harmful chemicals. Home Master’s innovative modular design eliminates common problems like canister filter housing leaks, slow flow rate, high water waste, and service challenges. It’s all backed by a 5-year limited warranty, and Made in the USA.

The innovative design of Home Master eliminates the most common problems found in traditional RO systems — canister filter housing leaks, slow flow rate, and service challenges. Home Master RO systems use larger fittings and tubing than traditional RO systems to double the flow rate, and the modular all-in-one filter design makes annual filter changes fast and efficient, reduces contaminant build up, and helps to eliminate leaks.

All In One All In One

Clean, refreshing water - FAST

Home Master TM Undersink Reverse Osmosis system uses sediment filtration, catalytic carbon and activated coconut shell carbon and reverse osmosis purification to remove up to 98% of chlorine & chloramines, chemicals, heavy metals, fluoride, total dissolved solids (TDS), pharmaceuticals, microplastics, and thousands of other contaminants.

Many tankless RO systems use imported ‘loose’ style membranes which can only achieve 90-94% reduction in total dissolved solids including heavy metals. Those membranes are intentionally loosely wound to allow for more flow, sacrificing purity to compensate for not having a storage tank. Home Master uses only the highest quality American made Dow membranes which can achieve up to 98% reduction in total dissolved solids including heavy metals.

The water flow from traditional RO systems takes 40 seconds to fill a tea kettle or large pasta pot – a level of performance that was unacceptable to Home Master’s engineers. The Fast Flow RO Kit (included with Undersink RO system) uses larger fittings, tubing, and high-flow components to effectively double the water flow from the RO faucet

Saves Time & Frustration | Easy change filters

Filter changes on traditional RO systems can be a real pain. They often require heavy tools, and brute force to loosen stuck canisters sealed shut by accumulated hardness minerals and icky contaminants. Home Master makes annual filter changes easier than ever before. Its modular design provides full access and visibility, and push-in-fittings make filter changes quick and painless– no wrenches required.

Modular Filter Design | Beautiful, not pretty

The most significant problem associated with traditional RO systems is the ‘canister filter housing’ design, where only the filters are changed, and not the filter housings. Sediment, microorganisms and biofilm can accumulate in the canisters and, over time, the canisters will weaken, begin to leak and ultimately fail. This can potentially lead to serious water damage and costly home repairs.

Some tankless RO systems employ a solid manifold design that is impractical to upgrade or service.

Home Master’s innovative system uses a modular design where the components are exposed and the ‘all-in-one’ filters are incorporated into their housings. This makes annual filter changes fast and efficient, reduces microorganism and biofilm build-up and helps to eliminate leaks. Home Master filters last longer than traditional RO systems’ filters — only requiring a filter change once a year or every 3,900 gallons. When it comes to installation, service and system performance – Home Master modular design is beautiful.

Save Time, Money and Water | Improved water efficiency

Home Master systems use granular carbon in the pre-filter rather than of carbon block to ensure the water pressure stays as strong as possible. Stronger water pressure to the membrane produces more water with less waste. Compare Home Master’s 8.5 inches of carbon contact time with the competition’s thin wall carbon block. More carbon contact produces cleaner water.

All Home Master RO systems use powerful catalytic carbon filtration media in the carbon prefilter to treat the very persistent chemical disinfectant chloramine. Ordinary carbon filters are unable to effectively remove this stubborn contaminant that is now being deployed nationwide to replace chlorine. It takes the more advanced carbon media known as catalytic carbon.

Some tankless RO systems fail to use a dedicated sediment pre-filter, forcing the entire sediment load into their carbon block which can slow membrane production, increase waste, maintenance requirements and costs. All Home Master systems use a dedicated 5-micron depth sediment pre-filter to prolong overall filter life, and ensure the highest possible water efficiency.

Home Master Does It Better | Better water efficiency, faster flow rate, reduced TDS creep

     The Home Master Fast Flow RO! kit and optional non-electric permeate pump upgrade solve several problems commonly found in other RO systems: TDS Creep, slow flow rate, and poor water waste. Home Master Fast Flow RO! kit nearly doubles the flow rate by incorporating larger fittings, tubing and other high flow components.

Some cannister and tankless RO systems fail to use a dedicated sediment pre-filter filter or use carbon block which can slow membrane production and increase waste, or increase maintenance requirements. All Home Master RO systems use a dedicated 5-micron depth sediment pre-filter to prolong filter life, and ensure the best possible performance.

This Home Master system includes a non-electric permeate pump to further improve system efficiency. This device reduces water waste by up to 80% and increases water production by up to 50%, with about a 1:1 waste ratio. It allows the tank to fill fuller, plus, it provides slightly cleaner water by virtually eliminating a condition known as -TDS Creep – a significant issue with some tankless RO systems. TDS stands for Total Dissolved Solids which includes the hardness minerals, salts, and heavy metals. 

Home Master systems with permeate pump address issues of TDS Creep by boosting pressure during the fill cycle, and keeping pressure to the storage tank and permeate side of the membrane constant. We increase efficiency by regulating the flow of water on both side of the system - feed water and permeate water. Furthermore, because our storage tank keeps purified water on tap, wasteful flushing is not necessary between common periods of inactivity.

Permeate Pump

Home Master's permeate pump upgrade further improves system efficiency, and does not use electricity. By reducing water waste (up to 80%) and increasing water production (up to 50%), your RO system will spend more time producing great-tasting purified water. Furthermore, by equalizing pressure on both sides of the membrane, TDS creep (an issue common with tankless systems) is greatly reduced. Expect about a 1:1 purified to waste water ratio.
