The Best Whole House Water Filter System

Protect your home and appliances by filtering all of your incoming water. The whole house water filter system is a type of home water treatment system that helps remove major contaminants from your water. A whole-house water filtration system is installed on your incoming water line to filter the water entering your home while protecting your plumbing and water appliances (such as water heaters, washing machines, refrigerators, and ice-makers) from sediment, dirt, sand, silt, and chlorine taste and odor. This means you will have a supply of clean water for cooking, drinking, bathing, and other home uses.

While preventing the damaging buildup of sediments, filth, and rust in your water heater, washing machine, freezers, ice makers, and other appliances, the Whole House Filter purifies the water entering your home.

What is the best whole house water filter for your home

The best whole-home water filter comes complete with a full filter set that includes a sediment filter and carbon filter.

The combination of both sediment and carbon water filters helps remove major water contaminants like chlorine, rust, pesticides, dirt, sand, insecticides, silt, turbidity, volatile organic chemicals (VOC), herbicides, cloudiness, industrial solvents, total organic carbon (TOC), pharmaceuticals, turbidity, odors, and cloudiness.

Filtered water is not only recommended for drinking, but even when bathing, you need filtered water to shower.

Contaminated water has an effect on your skin causing it to dry or other skin problems.

Also, contaminated water also has an effect on kitchen appliances or other gadgets in the house.  

To prevent all these overall problems caused by contaminated water, it is high time to consider filtering your whole house water.

This can only be done by installing a whole house water filter.

What is a whole house water filter?

The whole house water filter is also known as the point of entry filter.

It is connected to the main water supply line and filters the water for the whole house before being distributed to the various outlets.

Why does every house need a whole house water filter?

Every person’s concern is the quality of the water we consume, but we don’t worry much about the water we use for cooking, bathing, laundry, cleaning the house, and dishes.

We all know the hazards of drinking unfiltered water, but why filter water to bathe in and clean it?

In most places, the main water supply is tap water and the government adds a chemical known as chlorine.

Chlorine disinfects water, kills bacteria, and removes other impurities in the water, making it safe for drinking.

However, chlorine itself is not harmful, but chlorine by-products can be very dangerous to our health. They can increase cancer risks. Chlorine by-products can damage and excessively dry out our skin and hair. 

We get exposed to chlorine by-products through:

  • Drinking chlorinated water
  • The body absorbs it through the skin when washing clothes, cleaning the house, and utensils using chlorinated water.
  • Lastly, by inhaling water vapor while bathing and swimming in a shower or swimming pool treated with chlorine.

The main reason why we need a whole house water filter is to get rid of harmful chlorine by-products found in water.

Read more about chlorine, harmful substances, and environmental risks in chlorinated water.

The whole house water filter is for families that need to filter every drop of water that enters the homestead. If you don’t want to filter every drop of water that enters your house, you can consider buying a faucet water filter, countertop water filter, or under-sink water filter.

A whole-house water filtration system will not only help reduce total dissolved solids (TDS) but instead keep healthy minerals in your water. If you are interested in a system that removes TDS, consider a reverse osmosis system.
