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, 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 5-year limited warranty. Home Master RO systems use larger fittings & tubing than traditional RO systems to double the flow rate. The Home Master undersink system uses an advanced purification process, which removes up to 98% of chloromines & chlorine, chemicals, total dissolved solids (TDS), heavy metals, pharmaceuticals, microplastics, & other harmful contaminates. All Home Master RO systems use powerful catalytic carbon filtration media in the pre-filters to treat the very persistent chemical disinfectant chloramine. Ordinary carbon filters are unable to effectively remove this stubborn contaminant now being deployed nationwide to replace chlorine. 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. The Dow Filmtec 50 GPD membrane optimizes purification while minimizing wastewater production. The most sophisticated components certified to NSF standards are included in the design and construction of our product.

  • Highly pure water: 5-stages of filtration and purification remove up to 98% of Chlorine and Chloramines, chemicals, lead, heavy metals, fluoride, microplastics, TDS, and thousands more; BPA and Lead free; 5-Year Limited Warranty

  • Faster Flow Rate: included Fast Flo RO! Kit has larger fittings and tubing to provide 2x the flow of traditional RO systems and 4x faster than tankless -- 4.5 seconds to fill 8 oz.
  • Modular design: easy to upgrade and service; filter changes once per year or 3900 gallons with no wrenches required
  • Catalytic Carbon: Home Master catalytic carbon outperforms ordinary activated carbon in removing stubborn chloramines, and other chemicals
  • Dedicated Sediment Filter : 5-micron depth sediment filter prolongs the life of down-stream filters, ensuring highest possible water pressure and reduced water waste.

          Fantastic! Really love this system, so happy with it, wouldn't go without one again. Tastes better than bottled, in our opinion. I liked that it had the best lead filtration, and once a year filter change. I've had this installed almost a year, and just purchased another, for the in-laws, who have a well. They couldn't believe the difference!! A great investment for your home, and your health!!

          Bought two unit. One works fine, the other is problematic. It stopped producing water after 2 weeks so I contacted the manufacturers. They sent me a new part (the little, round metal valve thingy), it worked for 2 more weeks then stopped producing again. I'll be returning this one in store.

              Must buy!
              My husband and purchased this system after reviewing many systems on the market. We called home master and discussed all possible options with them and boy were we amazed. They were very helpful in the decision process and made it easy for us to decide which system to go with. They are made in USA and use high quality parts that are NSF certified to build every unit. The filter replacement for this system is only 49.95 once a year. They had said the installation would be a breeze and it was. My husband wanted to higher a plumber, but the company had said not because the systemic DIY. I made my husband a nice dinner and made him install it. He installed the system successfully in about a hour or so. The water is very tasty. You can totally tell the difference in the way my coffee taste and pasta. My sister visited me later in the week and tasted the water and surprised as well. The flow is way stronger than out old ro. Now I can fill things up faster and really wash the dirt off many home grown veggies. This state is a must have. I would recommend to all family members and to you. I hardly ever write reviews, but home master deserves it. I never have to worry about buying water ever again!
