materials and performance
NAQWA SWR units are made of materials approved for contact with drinking water. All materials are BPA-free, as there is no BPA content in any materials used in NAQWA SWR filters. The tubing is made of the highest quality medical grade silicone.
The purification quality of drinking water remains unchanged throughout the life of the NAQWA SWR-SPRING operating unit. When handled properly, NAQWA SWR drinking water recoverers last for at least 12 months, producing up to 20,000 liters (up to 5,000 U.S. gallons) of top quality drinking water per year (50 L or 12 U.S.G. per day) which is enough to support about 20 adults a day. Water passing through this unique membrane retains all the useful trace elements, and the membrane traps and seals the unsuitable ones. The memory of any prior toxicity held by water would therefore be removed as well.
NAQWA SWR capacity may be reduced, over the course of time, due to filtration of highly contaminated raw water. In such cases the recommendation is to allow the raw water to settle prior to NAQWA treatment. NAQWA SWR-SPRING capacity also may be reduced as a direct result of user damage to the track membrane cartridge. The NAQWA SWR track membrane will not purify salt water.
