Water purification has slowly become a necessity with water pollution being at its peak and new unidentified impurities making their way into the water. With that in mind, it is essential that your household has a good water purifier that can get rid of almost all impurities without wasting water.
There are very few water purifiers that would give you a good all-round protection from impurities within your budget. Here are a few points that would help you purchase the right purifier:
Water purifiers generally use RO, UV, UF or a combination of these technologies to purify water. Choosing the right purification technology depends on the normal water supply. If the tap water or municipal water is brackish or contains chlorine, RO purification technology is a necessity. UV or UF or both of them are necessary when there is a tendency of waterborne diseases in your locality. For the best purification, you should go for purifiers with all these technologies.
You should always consider your budget before buying anything. The same goes for a water purifier as well. A good wall-mounted purifier is going to cost more than INR 16,000 and top models with LED displays cost maximum INR 25,000. These are purifiers that use RO technology, so you would never have any problem caused by hard salts. If you go for just UF or UV purifiers, you can get them for as low as INR 9000 too but as the major problem in municipal water is brackishness RO technology should be chosen.
Water Rejection of RO:
RO purification doesn’t purify the entirety of the water that is sent into the purifier. Most of the water is discarded with all the impurities. This water is completely hard water and can’t be used for drinking purposes. Therefore, you should consider buying water purifiers that has “Save Water Technology” added in it, which will purify at least 50% of the entire water supply. This way, you have 50% of the water for drinking purposes and the rest of the water can be used for washing and mopping purposes. This results in 100% of the water being saved.
Traditional water purifier makes you wait for a few minutes before they provided pure water. Don’t go for such purifiers as they have a very low purification capacity and production rate. The purification capacity should at least be 15 liters per hour. This way, the purification of water is done as soon as the storage container starts getting empty.
There are few water purifiers that have storage tanks, which can store pure water and few others that don’t have these storage tanks. Having a storage tank benefits you as purified water is readily available whenever you want. With purifiers without tanks, you would have to wait around while the water gets purified. Generally, water purifiers have about 8 liters of capacity, which is more than enough.
Almost all water purifiers have replaceable filter cartridges and you should choose your purifier accordingly as well. A filter cartridge lasts minimum six months and maximum twelve months after which you need to replace it with a new one. Don’t go for purifiers, which ask you to replace cartridges quicker than that. Filter cartridges aren’t cheap and replacing them before their lifetime isn’t advised.
This six point checklist has everything that you would need to consider while purchasing a water purifier. Keep these points in mind and purchase the right purifier for your household and always drink 100% pure and safe water.
