Cleanliness is our top priority at Urban Float and how we keep our float pods clean is one of the top questions we are asked. In a well-maintained system, the flotation tank solution is far cleaner than any public pool or hot tub you’ve been in. To take it a step further, the float tank has no chlorine or added chemicals to keep it clean. In order to keep a commercial float tank sanitary, clean and safe it requires constant cleaning, maintenance and monitoring of water levels, H2o2, salt levels and PH. It is also important to follow the Float Tank Association standards as well as other useful resources to maintain a sanitary and chemical free float experience. Sanitation Starts with High Concentrations of Epsom Salt (Magnesium Sulfate) Our tanks have over 1,200 lbs of Pharmaceutical grade Magnesium Sulfate (Epsom Salts) in 10inches of water bringing the salt concentration to nearly 35%. This high concentration of magnesium sulfate prevents nearly all organisms from multiplying, and will often kill them off over time. But rest assured that we do not rely on just the Epsom Salt to keep things clean, nor does any other float center. The salt solution in each of our float pods is filtered 3-4 times between each user to pull out any organic impurities. The water is pumped through our filtration system which includes a 1 micron filter (catches everything half the width of a human hair). Each of our float pods is connected to it's own commercial grade filtration system that could clean an olympic-sized pool, but is dedicated solely to that specific float pod. We also use Ultraviolet light and hydrogen peroxide during the filtration process. After each guest is finished floating, the rooms, showers and pods are thoroughly cleaned and prepared for the next guest.
