In turn, you are provided with safe, healthy drinking water all from the convenience of your kitchen sink, or any other chosen faucet. Because this mode of water filtration is rather inexpensive, as well as portable, they are very popular for households across the world. If you are in the market for a point-of-use faucet filter, we have laid out the top rated kitchen sink water filters below.

How Water Faucet Filters Operate

Essentially, faucet water filter connects to a water faucet, such as the one on your kitchen sink. Contrary to popular belief, this type of water filter routes water through a filter faucet, through rather than through the faucet in your kitchen. How does filtration work?
  • Water filtration begins through the removal of sediment. Typically, a non-woven screen surrounds a filter cartridge, which is utilized in order to catch debris. Small and large particles are caught, such as sand, rust, dirt, and more.
  • The second step to water filtration involves an activated carbon block. A single granule of carbon is covered in countless little pores, which catch and remove various chemicals through absorption. When the carbon is allowed more contact time with the tap water there is a higher rate of chemical absorption. This is where a slightly slower flow rate comes in handy.
  • Additional contaminants are removed through additional layers, thanks to a final step of filtration. Although a screen and carbon block work well together at removing various contaminants, other elements such as heavy metals may flow on by. A chemical removal process helps to remove anything that may have been left behind.
  • The water filtration quality is set by a public health and safety organization, known as NSF International. Their goal is to improve human health on a global scale, accomplishing tasks through the testing and certification of products such as water filters and purification systems. Standards are set and adhered to by certified products, which brandish the NSF/ANSI 53, or NSF/ANSI 42 logo – depending on the standards adhered to. In order to meet various guidelines, the NSF ensures standards remain stringent, and products maintain overall quality. Consumers may feel confident in water filters certified by the NSF, mostly due to the reduction of impurities, or the removal of contaminants known to cause adverse health effects.
