A water purifier is a household appliance that filters, purifies, and/or distributes water. We take a look at the best types of water purifiers to buy in 2018. Some people choose not to install a traditional filtration system in their home due to cost and time constraints, so they instead purchase a drinking-quality purifiedwater dispenser with one or more reusable filters. These types of devices are usually small enough that they can be placed near sinks or on countertops and are designed for consumer use (unlike commercial models). The WHO recommends replacing your filter every six months as it will lose its ability to eliminate viruses and chemicals when left unused for too long, with some exceptions. The replacement period is also dependent on the quality of the water you are filtering. Tap water generally needs to be replaced far more frequently than water taken from a natural spring, for example, where the levels of contaminants are very low. Image source: https://www.amaz
