taste & pre-treatment
NAQWA SWR (SPRING and SHUNGITE) models offer similar performance. Both models offer superior water structuring, water memory removal and contaminant removal. NAQWA SWR-SPRING offers a slightly improved flow rate over NAQWA SWR-SHUNGITE.
NAQWA SWR-SPRING requires NO initial filtering of water prior to use, and may be used immediately.
NAQWA SWR-SHUNGITE features a Fullerene-Enhanced track membrane cartridge and DOES require some initial filtering of water prior to use.
Initially, the NAQWA SWR-SHUNGITE Fullerene-Enhanced cartridge may produce an excess of shungite mineral taste in the water for the first 10 liters or so (approx. 2½ U.S. gallons). Further along, the taste returns to normal. It is recommended (for improved taste) that the user allow about 2½ U.S. gallons of water to be filtered through the shungite track membrane cartridge before drinking. This is a specific feature of shungite, and people who use shungite regularly are well acquainted with its specific mineral taste, initially.
