STOP! Reverse osmosis membrane Fouling with Advanced IRON filtration found in the Home Master IRON.

Designed for High Iron (>0.3ppm) water supplies.

The Home Master IRON Undersink Reverse Osmosis System delivers solutions, not problems. Even the most health conscious individuals will be impressed with its exceptional water purity — as it removes up to 98% of Iron, hydrogen sulfide, chlorine, chemicals, heavy metals, solids and other contaminants from your well water of municipal water source. The advanced redox media alloys found in the Home Master IRON filter act as a catalyst to chemically change soluble ferrous cations (clear, dissolved iron) into insoluble ferric hydroxide, which is then trapped in the IRON filter’s sediment filtration layer. With enough dissolved oxygen in the water, iron removal rates of 98% or better are possible. Home Master’s innovative design eliminates the most common problems found in traditional RO systems — canister filter housing leaks, slow flow rate, and service challenges. It’s all backed by a five-year limited warranty, and U.S. technical support.

Home Master IRON uses five stages of filtration and purification to produce exceptionally clean water. Sediment, iron, and carbon filtration, together with reverse osmosis purification remove up to 98% of chloromine and chlorine, iron, chemicals, heavy metals, fluoride, dissolved solids, pharmaceuticals, microplastics, and thousands of other contaminants. Also, the type of dissolved iron commonly found in well water will destroy the reverse osmosis membrane without the IRON pre-filter protecting it. The Home Master’s superior Iron pre-filter, which contains an advanced redox media KDF85 acts as a catalyst to help remove dissolved iron from the water. (The UV sterilization chamber is always on guard and safely destroys 99.99% of germs, viruses, bacteria, and other microorganisms without dispensing hot water at the faucet. This all results in exceptionally pure, safe, great-tasting water.)

Many tankless RO systems use imported ‘loose’ style membranes which can only achieve up to 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.

Additionally, 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 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.

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 RO system design today 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 3,000 gallons. When it comes to installation, service and system performance – Home Master modular design is beautiful.

Home Master IRON systems use granular media 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 combined carbon/KDF85 filtration media contact time with the competition’s thin wall carbon block. More carbon/KDF85 contact time produces cleaner water.

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

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.

To further improve system efficiency, Home Master offers a Permeate Pump upgrade on all RO systems. 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 IRON systems ran with our permeate pump option 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 sides 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.
