What Is An Undercounter Water Filter?

An under-counter water filter is a filter you install at the point of use (POU). You install the water filter exactly where you need clean water.

Undercounter filters are in-line filters, which connect directly to your waterline. Water passes via the filter to the faucet. Undercounter water filters are a popular water treatment solution for many homeowners.

There are several types of water filters, which include:

Activated Carbon

Activated carbon is good for absorbing organic substances, agricultural chemicals, sediment, magnesium, chloroform, and chorine. The key to how activated carbon works is absorption. Water contaminants stick to the carbon as they pass through the filter.

Ion Exchange

Ion Exchange is suitable for removing radioactive material and hard water. This type of filter has a substance that exchanges ions as water passes through.

Reverse Osmosis

Reverse osmosis is ideal for a high percentage of contaminants. As a result, this type of filter is prevalent. It uses pressure to push water via a reverse osmosis membrane, leaving contaminants behind.

Mechanical

Mechanical filters use the pre-filtration method, which is ideal for matter waste and physical properties. Water flows through a mechanical filter leaving behind waste material. This filter is a type of sediment filter and is suitable for a well water filtration system.
