After passing through GuttaFilta and GutterFoam, Rain Water is unaffected by the foam insert. Both products have undergone rigorous testing against the National Health and Medical Research Council’s Australian & New Zealand Drinking Water Guidelines 2011 (ADWG); the Australian and New Zealand Environment and Conservation Council (ANZECC) Guidelines for Fresh and Marine Water Supply; and World Health Organisation (WHO) Guidelines for Drinking Water 2011, 4th Edition.
The tests show that our foam inserts have a negative effect on water tested. If the water is suitable for drinking prior to passing through GuttaFilta or GutterFoam it will be suitable after passing through it (provided the receiving receptacle such as a water tank isnot contaminated). Tests show that GuttaFilta & GutterFoam add nothing to water that will contaminate it.
Our advice is, because GuttaFilta™ and GutterFoam are designed to keep your gutters clear of tree debris and not pollutants or other impurities, always get professional advice on your drinking water quality.
