This whole house water filter is specially designed to treat well water. The water goes through multiple filtration stages to become clean, healthy, and safe to use and drink. It comes with a salt-free descaler and UV filtration system to make your well water clean and free from contaminants.

The unit is designed to provide maximum filtration without a need for regular maintenance. It’s unique upflow and dual-tank design is responsible for increasing the time that the water spends within the contaminant removal media resins. Also, it prevents clogging to never reduce the flow rate. The water tanks are quite long-lasting. Also, the filters are easy to replace.

When the well water enters into the filtration system, it meets with the sediment-pre filter. And then it goes into the salt-free softener, copper-zinc & mineral stone, activated carbon filter, sub-micron post-filter, and the UV filter. Each filtration stage works well to remove various contaminants and pollutants.

The sediment pre-filter is of 20-inches that is two times effective than the 10-inch pre-filter. It makes the water free from sediment, rust, and silt. The salt-free softener stops minerals from forming scale build-up. And the copper-zinc & mineral stone is responsible for cutting down heavy metals, chlorine, and scale along with restricting the development of bacteria and algae.

The activated carbon filter is used for the removal of different chemical compounds, herbicides, and pesticides. The purpose of adding a sub-micron post-filter is the elimination of remaining particles and sediment. And in the end, there is a UV filter that removes viruses, bacteria, and germs.

This whole house well water filter doesn’t need drainage lines or backflushing. Also, it doesn’t include any contaminant back into the water.

What is Well-Water?

Water that comes through our pipes is pumped out from the ground and often contains all kinds of minerals and impurities. Well-water comes from rainwater that is stored in underground porous rocks. Underground water often absorbs magnesium, chlorine, chlorides and other contaminants while underground. According to this article, contaminants like these can become harmful in larger quantities. They can also make our water taste or smell weird. This is why well water must be properly filtered before use.

A whole house water filtration system will help remove all harmful bacteria from your water that gives it a bad taste and odor. The water is filtered either through a biological process or a physical barrier, both are equally effective.

Why do you need one?

UV Water Filter & Softener for Wells (4-6 Bathrooms)

Clean drinking water is a necessity for most of us and something that shouldn’t be compromised on. Most of the regions we live in have water sources that require filtration. Well-water comes from the ground and contains all kinds of harmful contaminants and impurities that can be damaging in many ways. The odor in well water itself is unnerving and comes from the bacteria present in it.

A whole house water filtration system would be effective in the removal of such elements and odor. It can provide you with a supply of clean and safe water at all times. These filters can effectively turn hard water into soft water.

Hard water vs Soft water

A whole house water filter system will ensure that the water running through your pipes is cleaned of any extra particles that make it “hard”. Most of us are not familiar with the term hard and soft water, so let’s see what they mean.

Hard Water

Hard water generally contains a greater amount of minerals including limestone, chalk, and dolomite. While these minerals are not harmful for consumption in small amounts, they can build up in your plumbing and damage it over time. Along with damaging your plumbing, they can also damage your skin and hair. Hard water tends to rob the skin and hair of moisture, making them dry and irritable.

Soft Water

When hard water gets treated for the removal of excessive minerals, it turns into soft water. Soft water tastes better, is less damaging for your body and doesn’t harm your plumbing either The treatment includes replacing mineral ions with sodium ions to reduce the hardness of the water. It is important to note that sodium can be unsafe for watering plants and so it should be avoided for this purpose. It is not otherwise harmful to your health.

Whole house water filtration systems are the most convenient and inexpensive way to treat your water for hardness when compared with other options. They are effective in removing contaminants. These filters are installed between your main water source and the faucet that distributes water to the rest of your plumbing. These faucets act as a barrier and stop the minerals from passing through them.

Things to keep in mind before investing in one

Drinking clean water is a necessity for all of us. Recent studies have raised questions regarding the quality of water we are consuming on a daily basis.

There are all kinds of filtration systems available in the market. This makes it hard to figure out exactly what sort of system should you go for. To make your task easier we have identified the key factors to look for before making your final decision.

You should learn more about the quality of your water supply. This will help you figure out the contaminants present in it and find a filter system that can effectively deal with them all. If your water supply comes from a well then a whole house water filtration system would be more suitable than purifier pitchers or other filters. Most water quality reports can be accessed online easily and can help you easily identify the different contaminants present in the water.

The other thing to look for is the filter types that most of these filtration systems contain. It is important to note that all the filters can remove basic contaminants, unpleasant smells, and improve the taste. The models especially focused on well water will treat other heavy metals, minerals, and impurities as well. The only drawback is that these filtration systems can be expensive to purchase and install. Another thing to look for is the flow of water and if the system will be able to provide you with enough water to fulfill your daily usage requirement or not. Your water flow should bet at least around 10 to 15 gallons per minute. Anything below this would not be sufficient to cater to bigger houses.

Cost is equally significant when it comes to making a purchase. You might want to get the best setup for the lowest cost, most of us do. However, these filtration systems can be expensive. It is important to note that you would not have to only pay the initial cost but also others including filter replacements and capacities costs. The last thing to look for is the storage and space required to install these whole house water filtration systems.

To sum things up, the key factors to look for include:

  • The quality of your water supply
  • Type of filters
  • Flow of water
  • Costs
  • Storage

All of these will assist you in making a decision that fits your needs the best.
