Whole House Water Filter for Well Water Buying Guide

If you’re not familiar with what well water is, let’s help you understand. Well water comes from the ground, hence, also called groundwater. People have long been using wells to get water from the ground on their land. There are many water supply companies and towns that are now getting their water from deep wells, bored into local aquifers. Water obtained from deep wells usually doesn’t require as much treatment as surface water. ​ Well water is basically stored in a threshold under the ground. A structure, known as well, is built to tap into it and supply groundwater to homes or other buildings for use. The process works by drilling a hole into the ground and using a pump to deliver fresh water from the well. Unfortunately, the water obtained from the ground is filled with various types of pollutants and minerals, known to be unsafe and detrimental for personal and household use. The most common contaminants found in well water are chlorine, magnesium, chlorides, and a number of other impurities. These toxins are not only harmful when in high concentrations but also make the water smell and taste bad. There are two effective ways of filtering well water, biological and physical.

Why you need well water?

In many regions around the world, especially rural areas, groundwater is a necessity. Besides, it’s a cheap and never-ending source of obtaining fresh water. Although, it’s highly crucial that you don’t compromise on the quality of the water supplied to your home and only use clean and toxin-free water for drinking and other purposes. Since well water comes from under the ground and contains innumerable contaminants that can be hazardous in a number of ways. The bad odor of well water alone is a result of bacterial development in the water. ​ This is the reason you need a whole house water filtration system to get rid of all kinds of harmful agents, smells, and odor from the well water.

The presence of excess heavy metals and minerals can make well water hard. A whole house water filter is useful in filtering out these impurities and keeping the water supply to your home well cleaned. If you have never heard of the terms ‘hard’ and ‘soft’ water, here’s how they’re defined:

  • Hard water is known as containing an appreciable percentage of dissolved minerals, like chalk, limestone, magnesium, dolomite, iron, and calcium. Though these minerals are not considered to be hazardous for drinking and domestic use when consumed in small quantities, their high amount in water can have negative impacts. Besides ruining your water pipes, they can impair your health, hair, and skin. Due to the high concentration of minerals, hard water strips the skin and hair of their essential moisture and leaves them dull, dry, and lifeless.

  • After the removal of extra minerals that turn the water hard, the resulting water is called soft water. Soft water is considered better in terms of taste and uses for other purposes, such as laundry, washing dishes, and bathing, etc. It doesn’t have any adverse effects on you or your plumbing. The only ions left in soft water after filtration are sodium ions that naturally eliminate the hardness of well water. As hard water contains calcium and magnesium, it reacts with soap and reduces its effectiveness in cleaning properly. Soft water ends this problem produces bubbly and rich foam. The only thing to bear in mind is that sodium may be harmful to plants in your home, so avoid using this water for gardening.

The most expedient, cost-effective, and trouble-free way of treating hard water and getting food-grade water is to install a whole house water filter in the house.
