Chemical free sanitization

What is the best way to keep your water clean?
Ozone is a natural purifier, 1000 times more powerful than chlorine when it comes to oxidizing (i.e. neutralizing) body oils and bacteries, that can rapidly develop in warm water.
Ozone (O3) exists of 3 oxigen atoms. In aqueous environments (read ‘in your hot tub’) the 3rd oxigen atom reacts with impurities in the water, thus eliminating them in the oxidation process, leaving only pure oxigen (O2) as by-product.
Ozone is used also in public pools, breweries and water purification plants.
BETTER
Ionization is a natural process in which atoms of natural minerals are electrically charged which makes them loose or gain electrodes. This is entirely safe and environmentally friendly because no harmful materials are used or generated. The ionised water is safe, clean and free of chemical odours. An ionisation system is also ideal for people with a sensitive skin type who want to stay away from desinfecting chemicals like bromine or chlorine.
BEST
The combination of ozone and ionisation is de easiest and most efficient way to keep the water in your hot tub safe and pure. And, on top of that, the system requires hardly any maintenance. With the ozone and ionisation systems that Northern Lights supplies, bacteria and algae have no chance in your hot tub. You can easily be a month from home without having to worry about the quality of the water. It has no chemical odour either, and when changing the water you can re-use it to spray the garden.
SO, WHAT DO THESE MINERALS DO?
Silver (Ag) ions kill over 650 types of bacteria such as legionella pneumophila, streptococcus, E-coli, salmonella…
Copper (Cu) ions prevent algae growth. Copper is recognized as one of the best algaecides known to man, yet safe for humans.
Zink (Zn) ions stimulate healing of the skin and prevent stains and rings on the hot tub basin.
