It acts as a flocculent, that is, it causes the contaminants to remain in a suspended state so that they can be easily removed by the standard water filtration process &#8211; without producing skin-irritating by-products.<\/span><\/p>\n<p><span>This cleaning system is equally, if not more, effective and is much kinder to skin.<br \/>\n<\/span><\/p>\n<div><span>&#8216;Chlorine is potentially harmful &#8211; some studies have found that the chlorine used in pools can increase a youngster&#8217;s risk of asthma up to six-fold&#8217;<\/span><\/div>\n<p><span>Yet just a handful of public\u00a0 pools in London and two in Yorkshire have this superior cleaning system.<\/span><\/p>\n<p><span>Without a change in statute requiring public pools to switch\u00a0 to ozone filtration, nothing will\u00a0 get done.<br \/>\n<\/span><\/p>\n<p><span>However, despite my many attempts to lobby MPs about initiating such a change, I&#8217;m met with either polite disinterest or glassy-eyed indifference &#8211; even though I sit on an all-party Parliamentary committee on skin.<\/span><\/p>\n<p><span>There haven&#8217;t been attempts to field even a feeble fight about the cost, though this would only amount to the higher initial\u00a0 capital cost of installing a new filtration system.<br \/>\n<\/span><\/p>\n<p><span>Once in place, ozone filtration could reduce the ongoing operating and maintenance costs because it is less damaging to\u00a0 the infrastructure of a pool\u00a0 than chlorine.<br \/>\n<\/span><\/p>\n<p><span>And when you consider the incalculable and potentially fatal cost of a child who fails to learn to swim because their eczema precluded them from getting into the local pool, then it doesn&#8217;t take much to do the maths.<br \/>\n<\/span><\/p>\n<p><span>Suffering with red, itchy, angry skin is difficult enough.<br \/>\n<\/span><\/p>\n<p><span>Not being able to take a swim when a solution exists to this mounting problem
