  • Water filter pitchers use filters to remove impurities from the water. These filters contain activated carbon, which traps particles in the water as it passes through.
  • Water is poured into the top of the device and passes through the filter before it is extracted from the reservoir.
  • As the water passes through the filter, it is cleaned and made safe to drink. The filters also improve the taste and smell of your drinking water by removing odors and reducing chlorine levels.
  • It removes impurities such as heavy metals, chemicals, pharmaceuticals, and other substances that can be harmful if consumed.
  • Some water filter pitchers also contain additional features such as mineral stones and pH balancers for added purification benefits.

Water Filter Pitchers Cannot Remove

Hard Water: Water filter pitchers are not effective in removing calcium and magnesium minerals that cause hard water.

Fluoride: Water filter pitchers cannot reduce fluoride levels in drinking water.

Chloramine: Chloramine is the combination of chlorine and ammonia that may difficult for activated carbon to remove.

Bacteria And Viruses: Water filter pitchers are not effective in removing bacteria, viruses, and other microbes. This is because the filtration systems used by these pitchers only block particles bigger than 0.5 microns in size. Bacteria and viruses are much smaller than this, so they cannot be filtered out with a water filter pitcher.

Asbestos And Microplastics: Water filter pitchers are not effective in removing asbestos or microplastics from drinking water due to the size of asbestos and microplastics. so they cannot be filtered out with these pitchers.
