Yes, desalinated water is absolutely safe to drink. Reverse osmosis desalination is a process that uses a membrane to purify seawater or contaminated and undrinkable water sources by removing the dissolved salts and harmful content. The seawater membranes used in desalination systems remove salt, bacteria, viruses, protozoa, and cysts from the raw water, producing fresh, potable water. The seawater membranes used in Spectra’s watermakers remove 99.5% of all of the total dissolved solids from the feed water source. This means that after running seawater through your Spectra watermaker, the purified product water is as good, or better than bottled water!
