Delta Fresh Water Filters
Delta Fresh US-1, US-2, US-3 Reverse Osmosis Undercounter System Replacement Water Filters And Reverse Osmosis Membranes.
Delta Fresh Reverse Osmosis Systems use slim-line replacement O-rings, housing wrenchs and replacement filter housing sumps. They originally came with a 3.2 gallon tank. We carry all the repair parts, faucets, tanks, filters, RO membranes, valves, tubes and connectors for all of the Delta Fresh reverse osmosis systems.
Minimum filter change is every 6 months for the sediment prefilter and every 12 months for all carbon filters. Change more often if your usage is higher than normal or you have bad incoming source water.
RO reverse osmosis membranes need to be periodically monitored with a to check the efficiency of rejection of the ro membrane. Use our simple online TDS recetion calculator to know when it is time to replace the membrane.
Simply enter your Feed Water TDS and RO Water TDS into the boxes above and click "Submit". The percentage of TDS Rejection will be displayed. We normally recommend membrane replacement once you drop below 75%. This may vary in areas with high TDS in the feed water.
