What is the Whole House Water Filter System?

As the name implies, the whole house water filter system is a device that can filter the water that is supplied to your household. This system is also called POE or Point Of Entry because it is installed in the main water supply even before it reaches all the taps in the house, washing machine or radiators.

Thanks to this type of system, we can be sure that our family uses water free of up to 99% of heavy metals and bacteria, regardless of where it is taken.
Whole house water filter system will extend the life of appliances such as washing machine, kettle, espresso machine or showerhead.

What should you consider when choosing the whole house water filter system?

Before we decide to buy the whole house water filtration system, we should check what model will fit our household. It is important to do it precisely because it will affect the system exploitation price, water flow, and the final quality of the filtered water.

Filters – In the above-mentioned whole house water filter systems, there are various types of filters adapted to specific types of impurities present in the water.
In the beginning, we should get a Water test Kit which will show us what kind of pollution occurs in our water. If our water contains a large number of bacteria, we should choose the model in which the UV lamp is; it can kill up to 99% of bacteria.
However, if in our water the amount of heavy metals predominates, it is enough to stock up with a device with a carbon filter.


Water Flow– This is one of the most important things that we should verify before buying the whole house water filter system. You should take into account how much water your household uses per day and how high the consumption is during the day. Most systems of this type can filter about ten gallons of water per minute, which is sufficient for the average family, but if the number of household members is more significant and thus the water consumption is higher, you should consider a system that will provide us with higher flow.


Filter Capacity – The longevity of the system is an important factor because it defines how often we will be forced to replace filters and hence, the costs incurred in this respect.
Most systems of this type have a capacity of 100,000 gallons, which for the average family means changing filters every 6-12 months, top products can be enough for 1,000,000 gallons or ten years.
At this point, you should calculate how much water we use in our home and how often we will be forced to replace filters, because it may turn out that buying a more expensive filter will be longer profitable in the future than buying a small filter and its frequent replacement

Why should I buy Whole House Water Filter System?

The doubtful quality of the water supplied to our household is the main reason why people decide to buy the whole house water filtration system. Not once have you noticed the sediment at the bottom of your kettle, it is a stone that settles in all equipment connected to a water source such as a washing machine or a coffee machine, thus shortening their life. Excessive consumption of water with a stone can also affect your health as it settles in your kidneys, which can cause kidney stones to appear over time.

Most water treatment plants add chlorine to it, which has its advantages because it removes a significant proportion of bacteria but also has disadvantages because regular consumption of chlorine can seriously affect your health. Chlorine also significantly affects the quality of our skin; its excessive amount can cause it to dry.

People who regularly consume large amounts of water usually buy it in bottles, which translates into greater plastic production and greater littering on the planet. By using the whole house water filtration, we minimize plastic production, thanks to which we have an impact on the purity of our planet. At the same time, we improve the quality, taste, and smell of our water.

The whole house water filtration system is able to supply water anywhere up to 99% free of pollution to any place in our household.
It improves the health of us and our family members, extends the time of operation of devices connected to water, and makes our lives happier.

How Does a Whole Home Water Filter Work?

Most whole house water filtration systems work on a similar principle and can be compared to one scheme. The differences occur primarily in the properties of filters and their intended use for a particular type of pollution.

In the first stage, the water that runs in the mainline gets into the filtration system, in this place, there is usually a sediment pre-filter which is designed to remove larger impurities such as sediment, sand or rust.

In the second stage, partially filtered water goes to the activated carbon filter.
This filter plays a crucial role in the whole process because it removes most heavy metals, residue residues, unpleasant taste, smell and chlorine. It works on the principle of a process called adsorption; it consists in the fact that the coal in the filter has a porous surface with numerous nooks that attract pollution.

In the third stage, the water goes to a copper-zinc filter whose holes are about one-micron size. This filter is designed to remove the remaining impurities such as heavy metals or chlorine that are currently in the water.
It can be said that this filter stops what is left of the carbon filter.
However, this is not his only role; he also has the task of softening the stone that is in the water.

Some producers use tools such as water softeners, descaling agents or UV filters to remove bacteria that remain after the filtration process.
