RO Wa­ter Pu­ri­fiers None of these 10 makes it 100% safe

Consumer Voice - - Test Report -

The qual­ity of drink­ing wa­ter is very important for hu­man health – and to­day this is truer than ever be­fore. Truer be­cause not only are our wa­ter re­serves de­plet­ing and get­ting pol­luted, but also ac­cess to safe wa­ter is un­equal. The wa­ter we re­ceive from rivers/un­der­ground re­serves is pol­luted with heavy met­als, bac­te­ria and path­o­genic or­gan­isms. (It is re­ported that ground­wa­ter in one-third of In­dia’s 600 dis­tricts is not fit for drink­ing as the con­cen­tra­tion of flu­o­ride, iron, salin­ity and ar­senic ex­ceeds the tol­er­ance lev­els.) Some of us boil the wa­ter be­fore drink­ing it; some of us buy pack­aged wa­ter reg­u­larly; some of us in­vest in wa­ter fil­ters and pu­ri­fiers. The last men­tioned is a rel­a­tively ex­pen­sive propo­si­tion but con­sumers are go­ing for it be­cause it is con­sid­ered to be the best bet against un­safe or con­tam­i­nated wa­ter. As of to­day, the mar­ket for re­verse os­mo­sis (RO) wa­ter pu­ri­fiers is grow­ing tremen­dously and var­i­ous brands are avail­able in this cat­e­gory. At the same time, even as wa­ter fil­ters/pu­ri­fiers with lat­est tech­nolo­gies – re­verse os­mo­sis and ul­tra­vi­o­let (UV) – have been de­vel­oped, con­for­ma­tion to guide­lines and stan­dards is not equal. These new, ad­vanced units have im­proved the qual­ity of wa­ter, but is their pota­bil­ity in sync with In­dian Stan­dard or WHO guide­lines? Do we, as con­sumers, know what im­pu­ri­ties is a wa­ter pu­ri­fier sup­posed to elim­i­nate? Do we even know what these im­pu­ri­ties are, not count­ing the usual sus­pects like bac­te­ria and heavy met­als?
