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. Home Master’s innovative modular design eliminates common problems like canister filter housing leaks, slow flow rate, high water waste, and service challenges. All Home Master Reverse Osmosis Systems include a 5-year limited.

Clean, Refreshing Water - FAST
Home Master TM Undersink Reverse Osmosis system uses 5-stages of filtration and purification to remove up to 98% of chlorine & chloramines, chemicals, heavy metals, fluoride, TDS, pharmaceuticals, microplastics, and 1000’s more contaminants (DOW Filmtec RO Membrane).
Many tankless RO systems use imported ‘loose’ style membranes which can only achieve 90-94% reduction in TDS including 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 TDS including 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 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 other 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.
The Right Tool for the Job
Consider the entire Home Master product line: interested in UV filtration, Mineral Water on Tap, systems made for well water, or all of the above? Home Master will ensure you have the right tool for the job. Consider the Artesian Full Contact TMAFC for Mineral Water on Tap, the ULTRA for enhanced Iron filtration + UV sterilization, or the HydroPerfection for 9-stages of filtration, purification, sterilization, and enhancement.
Regardless of the system you choose, all Home Master models deliver the high quality, great-tasting purified water you demand.

Modular Filter Design – Beautiful, not Pretty.
The most significant problem associated with traditional RO systems is the ‘canister filter’ 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, 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 prevent 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.

Home Master Charitable Foundation
Perfect Water Technologies, Inc., owner and maker of Home Master Brand products, has always held philanthropy among its core motivations and has given generously to a variety of worthy charities. Particularly close to our heart is ending food insecurity. In 2020 we created the Home Master Charitable Foundation, a vehicle to focus, drive and increase our company’s giving.





Save Time, Money and Water
Home Master Systems use granular carbon in the prefilter rather than carbon block to ensure the water pressure stays strong. Stronger water pressure to the membrane produces more water & less waste. Compare our 8.5” of carbon contact time with the competition’s thin wall carbon block. More contact time = cleaner water.
All Home Master RO systems use powerful catalytic carbon media in the carbon prefilter to treat the persistent chemical disinfectant chloramine – now being deployed nationwide to replace chlorine. Ordinary carbon fails to address this new treatment, it takes the more advanced carbon media known as catalytic carbon.
Some tankless RO systems fail to use a dedicated sediment prefilter, forcing the entire sediment load into their carbon block which can slow membrane production, increase waste, maintenance requirements & costs. All Home Master systems use a dedicated 5-micron depth sediment prefilter to prolong filter life, and ensure the greatest possible efficiency.

Product Quick Look
- The Home Master Undersink Reverse Osmosis System delivers solutions, not problems. Its innovative design eliminates the most common problems found with traditional RO systems- canister filter housing leaks, slow flow rate, high water waste and service challenges. Its superior performance has made it one of the best RO systems on the market and it's all backed by a five-year limited warranty. Home Master RO systems use larger fittings and tubing than Traditional RO systems to double the flow rate. The Home Master Undersink Reverse Osmosis System uses an advanced purification process, which removes up to 98% of chemicals, dissolved solids, metals, and other harmful contaminants. All Home Master RO systems use powerful catalytic carbon filtration media in the carbon pre-filters 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. Home Master's innovative filters use a modular 'all-in-one' design where the filter is incorporated into the filter housing and the entire filter is disposable. This makes annual filter changes fast and efficient, reduces contaminant build up-and helps to eliminate leaks. Also, our granular filter causes less pressure loss so the RO membrane can function more efficiently and waste less water. In designing the Home Master a sophisticated combination of flow restriction components and 50 gpd Dow Filmtec membrane were integrated into the system architecture for optimized purification and minimized wastewater production. Components certified to NSF standards included in the design and construction of our product. In the Box: Fully assembled purification unit, storage tank, filters, 3/8-Inch feed water adapter with shut off, chrome faucet, faucet adapter, tfc RO membrane, drain saddle and instructions. Made in the USA.
