Bromine also produces less byproducts when it interacts with water pollutants, which results in less odour and less irritation to the skin and eyes.

The decision between chlorine and bromine is ultimately a matter of taste. You must choose which method best suits your needs because both are excellent at sanitising your hot tub.
