Thunder 4000M Reverse Osmosis System with UV

Thunder 4000M RO and UF System by Crystal Quest is an Under Sink, 17-stage Reverse Osmosis System combined with dual Ultrafiltration membranes and UltraViolet sterilizer for purest drinking water directly from your tap. 4000M RO Systems are designed with history and longevity in mind and incorporate latest water purification technologies available. Decades of research have produced totally new most effective, healthiest drinking water system on the market today.

The filtration stages are distributed into 6 filter cartridges and a membrane capsule which effectively removes up to 99.9% of undesirable contaminants and particles as small as 1/1000 of a micron by forcing untreated water through a semi-permeable membrane. Pressure forces the water to flow in the reverse direction to the direction of flow in natural osmosis through a membrane to capture most contaminants. Filter components include a Solid Carbon cartridge, RO membrane, 2 UF membranes, 2 standard multi-stage(6-stage) cartridges and an UltraViolet cartridge. The last stage is an inline Ultrafiltration membrane capsule for storage tank to prevent bacteria growth. Choose between 50, 75 or 100 GPD (gallons per day) reverse osmosis membranes (higher number means more gallons of filtered water produced per day). Thunder 4000M systems can produce up to 100 gallons of top quality water per day and have compact designs that can easily fit beneath the kitchen sink.


The Thunder 4000-M Reverse Osmosis and Ultrafiltration Under Sink System is capable of removing drug residues and virtually all pharmaceutical contaminants from water!
