Ef-Chlor 1.67gm Water Purification Tablets for Overhead & Underground Tank Water 1-Tablet purifies 500 litres Water-Jar of 50 Tablets Combo Pack of 2 jar (100 Tablets purify 50000 litres Water)

Usage of these chlorine tablets are recommended if your water contains sediments and an RO is not a great option. I use it for my rooftop water tank and drinking water filter. The package indicates that 1 tablet is to be used for 500 ltrs and it is recommended to use 2 tablets for a 1000 ltr tank. Too much chlorine in the water can lead to hairfall so it is recommended to use as mentioned in the package. Best season to use is Monsoon when water contamination can lead to stomach infections, jaundice, and other gastro intestinal problems. The tablets are soluble so it is easy to use. The quality of the product is great.

It's a great little product, I was skeptical before buying but I have used 8-10 for my 5000 liter underground water tank, works like a charm. The water smells fresh and although there is a very mild smell of chlorine it's nothing that could ruin your experience. Overall would recommend.

Super quality. Every one should buy this item. I bought it for metro water cleaning. It is really works well

Good product ! Fast Delivery ! Very Good Packing ! Nothing special with this product. As per instructions used it but nothing will happen to the purification of water the water is as it is..
