What is Ozone?
Ozone is a gas created when oxygen (O2) molecules are split into two separate atoms by ultraviolet radiation from the sun, lightning and electric arcs as used in our ozone generators. The split atoms recombine in three-atom groups to form cousins of oxygen known as ozone (O3). Being a gas it is ideal for use in hard to get to areas for odour removal, sterilising and mould treatment plus ozone has multiple other uses in all types of industry. Its is also ideal for asthma and chemical allergic people as the gas is not residual and converts back into oxygen after approximately 20 minutes meaning it is perfectly safe to use*
We use a machine to create natures ozone in a concentrated quantity
Bacteria, moulds and fungi (mildew), which can cause unpleasant odours, allergic reactions and sometimes disease, are killed when they react with ozone. As with chemical pollutants, the outer membranes or shells of these micro organisms contain receptors that absorb ozone and breed viruses and bacteria. Ozone will penetrate the membrane and proceed to break it down. Without its protective membrane or shell, the bacterium, virus, mould or fungus dies very quickly. Odour molecules will be completely destroyed
Odarid NZ Ltd is particularly active in working with animal care facilities to eliminate non enveloped viruses such as Feline Calicvirus (which causes cat flu), Feline Panleukopenia virus from hard to sanitise surfaces. Ozone can be installed and measured to ensure a 100% kill rate is obtained quickly and efficiently
Is ozone safe? Like virtually everything -- even oxygen -- ozone can be harmful if you're exposed to too much for too long. As mentioned, natural outdoor ozone levels in clean environments vary between .03 and .05 parts-per-million. The Food and Drug Administration (FDA) declares .05 ppm as the safe level for 24-hour-a-day inhalation. This is a conservative standard, since natural levels of ozone often reach .065 ppm -- 25 percent higher than the FDA's "safety" limit. In mountainous areas at higher altitudes the naturally occurring level of Ozone can be up to eight times higher than that (including places with among the highest life expectancy figures in the world).
Relatively high levels of Ozone can be safely employed in environments where people live and work because Ozone is neutralised immediately upon oxidising harmful chemicals, pollutants and bacteria. In addition, unutilised Ozone has a half life of only twenty minutes... so Ozone levels can be reduced exponentially when required . It is for these reasons that timer based systems are very effective for use when higher levels of Ozone are required in spaces which must subsequently be occupied. Automatically turning off a very high output Ozone generator an hour or so before returning results in an environment which contains a significantly reduced Ozone level (Ozone level @ 20 minutes = 50% of initial level; Ozone level @ 40 minutes = 25% of initial level; Ozone level @ 60 minutes = 12.5% of initial level etc.). In addition, opening a door or window can provide an immediate reduction in levels.
For people who suffer from allergies and environmental sensitivities, or those who just want to freshen up musty, smelly basements; "ground level" ozone can be a powerful ally.
*Do not breathe in the gas and always allow the room to clear (approx 30 mins with windows open) before entering |
