7 Best Faucet Water Filters in 2022 (In-Depth Reviews)
There are many contaminants that can be in tap water that can prevent you from getting high-quality, clean water from your water supply. There are chlorine and chloramines, that might affect water taste or odor and prevent you from getting great tasting water. There are minerals that cause water hardness, like magnesium and calcium that can cause build up in your pipes and be a complete hassle to deal with. There are contaminants that might cause discoloration, unpleasant smell, and bad taste, including sulfur and rust.
There are larger particles, such as sand, dust, dirt, and other sediments. There are bacteria and cysts, especially in well water. There are lead and other heavy metals. There are pesticides and other harmful chemicals. This is where filtered water comes in. This means no more need for bottled water, meaning you do not have to waste your money on water bottles. A water filter (or a water purifier) can remove all of these contaminants through different processes (such as reverse osmosis) and makes it so that the water coming out of your faucet into your kitchen sink is clean and pure.
The filtration process will make sure the water flow will be purified and cleansed and whether you need cold water or hot water you will be getting the best kind of water. Water filters (whether countertop, under-sink, or faucet water filters) might also include a remineralization filter, which adds healthy amounts of calcium and magnesium to the water. This is a lovely added feature that not all water filters have. This article will act as a buying guide for all your sink water filter needs.
