EASY TO USE BY SELF TESTING. IT SHOWS YOU ALKLINE FILTER'S WORKING CONDITION & YOU CAN ENSURE ABOUT LIFE OF CARTRIDGE. JUST TAKE 100ML OF WATER IN CLEAR GLASS AND ADD DROPS IT WILL CHANGE COLOUR OF WATER. MATCH CLOUR WITH DESCRIBE ON BOTTLE FOR GET RESULTS. DO NOT DRING WATER WHICH INCLUDES DROPS IT MAY CAUSE HEALTH ISSUES. FOR BETTER PERFORMANCE USE BIOWAY PRODUCTS.VERY USEFUL HANDY PRODUCT FOR PERSONAL & EDUCATIONAL & AQUARIUM & LAB USE.
