What Is An Inline Water Filter?

Inline filters are one of the most popular forms of water filters. They are applied inside the water line and connected between the water main and the tap. These filters are usually more cost-effective than other filter types and have a faster flow rate.

How Does Inline Water Filter Work?

An inline water filter can be inside the pipe. It filters water as it passes through the system from one point to the other. This process occurs continuously and uninterruptedly, which is better than older models, where you have to wait for a while for all the water to be filtered before switching on the tap again.

Inline filters usually consist of two filters for water quality, such as sediment and carbon filters. The first stage removes coarse sediments and particles from the water, while carbon block filters remove odors and provide an additional level of protection from chlorine or chloramines in drinking water, which are harmful chemicals that can cause health problems like cancer and organ failure.

What Do Inline Water Filters Remove?

Inline water filters are mechanical devices you can install inside your kitchen sink. They come in with different sizes and shapes and offer various benefits depending on the type you choose.

Choosing the right inline filter for your needs starts with understanding what it is capable of removing from your drinking water. Inline filters eliminate rust, sediment, silt, sand, dirt, limescale buildup, and many types of metals that could be present in your tap water. The most common types of inline filters are activated carbon and those that use a dual-media system to filter out particles much smaller than those found in tap water.
