## Description

Portable Mini Reverse Osmosis RODI Water System 4 StageTHIS REVERSE OSMOSIS WATER FILTRATION SYSTEM COMES WITH QUICK CONNECT FITTINGS, FOOD GRADE - COLOR CODED 1/4" TUBING FOR EASY INSTALLATION. ALSO INCLUDES A GARDEN HOSE ADAPTER.STAGE 1: INLINE SEDIMENT: Sediment removes dirt, rust, dust, chemical resistance, scale and sand particles.STAGE 2: INLINE CARBON: Carbon is used to polish the taste of the water and remove any residue from the storage tank. Made with the finest apricot shells, palm shells, walnut shells and olives to ensure world class drinking water.STAGE 3: RO MEMBRANE: The membrane will remove upto 99% of total dissolved solids (TDS) and contaminants such as arsenic, lead, fluoride & many more.STAGE 4: INLINE DEIONIZER: The Deionizer removes almost all of the harmful mineral ions such as cations like sodium, calcium, iron and copper; and anions like chloride and sulfate- Test conditions: permeate flow and salt rejection based on the following test conditions: 250 ppm softened tap water, 77°F (25°C), 15% recovery and the specified applied pressure (65 PSI).- Minimum salt rejection is 96%.Permeate flows for warranty evaluation may vary +/-20%.WHAT TO EXPECT:This RO system purifies 1 gallon of water every 14-19 min (very slow, water purification output depends on membrane Gallons Per Day rating, water dripping not flowing). RO membrane splits water with 0.0005 micron filtration, approximately 1000 times more effective than any water filter without membrane). We recommend to collect water in advance (every day or every second day) to always have it on hand. Use any kind of water container (glass or plastic).
