This Neo-Pure RO-Pure 50 gpd Membrane Filter
 effectively reduces a wide range of contaminants such as arsenic, lead, nitrates, perchlorate, chromium, copper, dissolved solids and cysts.

The optimized design of the Neo-Pure RO-Pure 50 gpd Membrane Filter 
takes the drain line out of the canister to eliminate the chance of waste stream bypass happening inside the membrane housing and ruining the quality of the RO water. Additionally, the flow restrictor on most RO systems never gets replaced and will shorten the life of the membrane over time. As the flow restrictor does its job, microscopic debris rejected by the membrane will slowly accumulate and then each new membrane replacement lasts less and less time due to not having adequate flow rate to drain. Each new Neo-Pure RO-Pure 50 gpd Membrane Filter
 comes with a new flow restrictor so shortened membrane life is never a concern or potential from this issue.
