The Invigorated Water website claims the PH001 filter that ships with this product, “Remineralises water with minerals such as zinc, iron, calcium, magnesium, selenium, lithium”. See https://invigoratedwater.com/products/alkaline-water-filtration-system-ph-recharge-glass I checked this claim out by having the water chemistry and mineral content tested by a state accredited laboratory. The tested water was re-mineralized using the pH Recharge Glass Alkaline Water Filter cartridge named above after being filtered though a five stage APEC reverse osmosis system, ensuring little if any mineral content in the water sample before being filtered by the re-mineralizing filter. The reverse osmosis (RO) system and component RO membrane and filters were essentially new on the test date (purchased new and in use for 19 days prior to the test) and had been verified to be functioning correctly, showing a total dissolved solids (TDS) reading of 3 ppm, a 97% reduction in TDS from pre-RO water samples. So the tested water had been stripped of virtually all contaminants, including most minerals. Because test results can be expected to be effected by the age of the tested filter (previous use cycles/days) and length of time test water is in contact with the filter while at rest in the pitcher, a decision was made to test the water after the filter had been previously used for 14 days at an estimated 3-4 gallons per day. This is approximately half the manufacturer’s recommended replacement period of “every month” for a family of four. The remineralized water was sampled first thing in the morning from a full reservoir sitting overnight, modified as follows: 64 ounces of water in the 160 ounce filtered water section (40%) of the pitcher was discarded and an additional 64 ounces of water was newly filtered before the test samples were drawn, resulting in a water sample of blended “overnight” water (60%) with “new” filtered water (40%). I believe this is the best compromise on how to test the water in “real world” conditions, and in fact should slightly favor an outcome of higher mineral levels. Test results were as follows: Zinc, 0 mg/L (not detectable with a reporting limit of 0.2 mg/L) Iron 0 mg/L (not detectable with a reporting limit of 0.1 mg/L) Calcium 0 mg/L (not detectable with a reporting limit of 0.5 mg/L) Magnesium 0.51 mg/L Selenium not tested Lithium not tested The test results show that of the four tested minerals claimed to be “remineralized,” three were not detectable in the water sample obtained from a two-week old filter. The claim that these minerals are added back to the water is mostly false. The pitcher does significantly raise the pH of the water. Sampling at various times and conditions resulted in readings of 8.2, 8.7, 9.8 and even 10.4 . The pitcher is handsome in appearance, works well if alkalinity is your primary use, and is of good build quality, but it mostly DOES NOT appear to “remineralize.” I gave this product 1 star because of the apparently false claim of reminerlizing water. I have a feeling few if any such products actually “remineralize.”
