The 4 stages of filtration for which this inline water filter is popular are effective for removing any kind of impurity from the water.
First, the water goes through stage 1 filtration where sediments and particles such as sand, dirt, rust, silt and undissolved particles are removed. The stage 1 filtration has a precision of 1 micron.
Then, the water goes through stage 2filtration, where it is rid of chlorine, chlorinated hydrocarbons, and hydrogen sulfide. It is also at this stage that bacteria, algae, and fungi are prevented from growing within the filter media and causing any harm.
The stage 3 filter has a high-quality substrate that completely eliminates trace organic compounds like Trihalomethanes (THMs), pesticides, herbicides and residual disinfection by-products like chlorine. In addition, at this stage, Bacterial growth is also inhibited, water taste is improved and odor removed.
Lastly, the final stage – stage 4 – removes residual chlorine and adjusts the water pH level. The water produced is alkali calcium ionized. It contains natural calcium, sodium, potassium and magnesium ions that can be absorbed by the body and provides nutritional benefits.
What is an inline water filter if it cannot provide you and your household the purest water for drinking and cooking. With 4 stages of filtration, there is an almost impossible chance of drinking contaminated water when using the Under Sink 4 Stage Direct In-line Tap Water Filter BLUONICS Purifier System.

How an Inline Water Filter Works?
The best inline water filters fall into the class of physical filters that sieve out large and small particles from water. This filter work using adsorption – a process of filtration that uses carbon.
In this process of filtration, the particles stick to the carbon pores – usually referred to as activated carbon. Additionally, charcoal, coconut, and ceramic are other materials used in inline water filters.
Inline water filters are connected inline with water sources and as the water passes through them, they filter out particles which include:
- Heavy metals
- Hydrogen sulfide
- Chromium 6
- Bad taste, etc.
Besides, the best inline filters not only filter water but adds calcium, sodium, potassium and magnesium ions nutritionally beneficial to the body. Also, it regulates the pH of water which provides clean cooking or drinking water to large and small households.
