Product Review

When you have water pressure at 65 PSI, this RO system generate pure water 4 gallons in 60 minutes (100 gallons a day)
Below 65 PSI, pure water will be greatly reduced. Below 35 PSI it won't work well at all.
The Pre-filter (1-2 stage) can work for 6-12 months and create the 2000-4000 gallons pure water.
The membrane (3rd stage) can work for 24-36 months and create the 54,000 - 110,000 gallons pure water.
Di filter works only for 300-400 gallons, to maintain 0 PPM pure water, DI filter must be replaced frequently.
DI water is safe for drinking but the taste may differ for everyone; it is usually used for reef water purpose, recommend add one carbon filter after DI when you use it for drinking purpose.
