## Description

Pure, clean and safe drinking water isn’t available easily these days. Growing population, industrial development and environmental degradation are all causes for this. Given this situation, it becomes even more important for us to be aware of purification techniques and the available water purifiers in the market to ensure that our drinking water is of good quality. A lot of minerals are found naturally in water and are important for the human body but consuming an excess amount of it can cause many diseases. A good water purifier removes the excess salts, suspended particles and microbes, and retains its essential vitamins and minerals. With so many manufacturers in the water purification industry these days, it is difficult to know which is good, which isn’t and which meets necessary standards. Both water filters and water purifiers work on the same mechanical principle. They first suck up raw water which is contaminated, filter out impurities ranging from sediments to micro-organisms and then dispense clean water. However there is one big difference between the two – a purifier can remove viruses and bacteria that filters cannot remove. If you want to purify water then Ef- Chlor water purification tablets would be your best option. This method of water purification is commonly used by all major departments due to their ease of use. They are also widely used during disasters such as floods when the available water is unsafe for drinking. Benefits of Ef Chlor Water Purification tablets There are many benefits of using tablets for water purification. The biggest benefit is that you don’t need sophisticated equipment Opens in a new window to make water safe for drinking. You also don’t need electricity as it is with All water filters. Therefore, it is one of the methods of treating drinking water. The tablets are small and light, and thus, portable. Water treatment tablets are also an excellent backup whenever equipment fails.

Review: HEALTH BENEFIT - 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.
Review: Great work done by these tablets - 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.
