We adhere to an extremely strict set of testing protocols. The water is tested several times a day for hygiene, specific gravity, pH balancing, sterilisation, and temperature. We send a sample of our water out to be tested by a third party regularly. Our filters are capable of screening the water down to as little as 10 micron (8 times smaller diameter than a human hair) and are regularly replaced. The entire contents of the tank is filtered 3-4 times between clients. The salt concentration alone will kill almost everything. Hydrogen peroxide and UV light in the filtration pump does the rest. You’ll find that our water is cleaner than a swimming pool and far more gentle to your skin.
