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.
