What is a whole home water fitler?

A whole house water filter it’s a type of water filtration system that treats your water before it enters your home. The filter type will differ on what are your needs and what is your type of water supply.

What are the types of water supply?

There are essentially 4 Types Of Water Supply;
1) Surface Water: Surface waters include streams, rivers, lakes, reservoirs, and wetlands.
2) Ground Water: It makes up around 22% of the water we use, is the water below the earth’s surface of the ground, where it travels through and fills openings in the rocks. The rocks that store and transmit groundwater are called aquifers.
3) Wastewater: Is any water that has been affected in quality by human activities. Wastewater can develop from agricultural activities, urban water use, and sewer inflow, and stormwater runoff just to name a few.

Wastewater from a municipality is also called sewage. Most of us don’t want to think about it, but at times the water that swirls in the bowl ends up being treated and ends up in our taps. Ew, right? That’s why you NEED to have a water filter.

4) Stormwater: Is defined by U.S. EPA as the runoff generated when precipitation from rain and Snowbelt events flows over land or impervious surfaces without percolating into the ground. This water runs over surfaces like asphalt containing pollutants like engine oil, fertilizer, and radiator fluid.

What are the main sources of water supply?

There are two principal founts of water: surface water and groundwater.

Groundwater corresponds to around 22% of the water we use. It exists in soils and sands that can hold water. The water table is the line between unsaturated soil and saturated soil. Underneath the water, the table is where rocks and soil are full of water.

Research in 2008 revealed private home wells form the largest share of all well water in the US, with over 13 million households having their well.

Surface Water it’s easily accessed and for that provides around 78% of the freshwater we use according to a 2010 USGS study. Over 1.2 billion people rely essentially on surface water, 90 million children in the US play and swim in surface waters every year.
The amount of water quantity may vary based on many factors like drought.

Do I need a whole house water filter?

For those who are health conscious, the benefits of using a whole house water filter far outweigh the costs. Do you remember what we talked earlier about most of the waste water becoming our tap water, right?

A whole house system filters the water at the point of entry to your house, which means that all the water gets filtered, not just drinking water, but the water you bathe in, wash clothes in and cook with. This provides maximum removal of chemicals for those that are serious about their health.

Interestingly enough, this type of filter not only helps remove pollution from water, but also from the air in your home.

Municipally treated water has chloroform gas in it, and according to the EPA, every home that uses it has elevated levels of this gas, which can cause severe respiratory problems because it gets dispersed  when the water gets heated. A filter that filters all the water in the house removes this chemical before it gets into your home, therefore no chloroform gas is present.

Another problem is that most people don’t realize that the contaminants in water can be absorbed through the skin. So even though you might filter your water, if you don’t filter your shower you can still be getting toxins from the water this way.

Many people consider filtering their drinking water as very important, but what about the water you cook with? This water is absorbed by the foods you are cooking and, ultimately, ingested into your body so you are still getting all the contaminants from municipal water if you cook with it.
