How Does a Whole House Water Filter Work?

It was hard work for the engineers to come up with an easy way to clean water, but now that it is a reality, the functionality of a water filter is very easy.


Usually, the best whole house water filter for well water has a mounting bracket or a framework that would help you install the filter on the wall. Without this installation process, the filter can’t function.

So, at first, you have to set up a place, gather all the tools and parts, follow the user manual, and then start connecting them. After installing the filter, you might have to fill it up and discard the first batch of water to get rid of any plastic smell and give a thorough wash.


Several models will give you the option to connect the intake pipe to the mainline or other containers. So, it is up to you whether you like the taste of hard water or soft water. The intake pipe may vary based on the brand.

For example, filters that have a huge capacity usually have bigger pipelines as well. The bigger pipeline helps in collecting water faster.

Installing the intake pipe in the right way is an important step; otherwise, the smallest leak can cause pressure loss and ultimate water loss.


The processing unit is the place where the device cleans the water. Each model may have their unique ways of processing. For example, carbon activated filters will focus on chemicals, while sand-stone filters will get rid of solid particles.

Some processing units are washable as well. But mostly you will have to discard it and replace it with a new one after a specific period.


The whole set of connections from the intake line to the discharging pipe forms an intricate network. Interruption at any step may cause the filter to disfunction. So, you always have to ensure whether the parts are clean and have adequate pressure.

Why Does Well Water Need to Be Filtered?

Water plays several important functions to regulate your body. For example, water transfers several nutrients to different body parts and regulates body temperature. So, the water you take must be pure; otherwise, it might be detrimental for your health.

Since water already contains its own chemical elements and other nutrients, harmful substances can mix with these nutrients and create other chemical components. So, this reaction is something you need to avoid.

By ensuring that your water has no foreign substances, you can restrict any form of a chemical reaction. Moreover, filtering will eliminate solid particles and toxic substances such as arsenic, rust, chlorine, etc.

Hence, you must check whether your water has optimum quality. You can easily ensure that with the help of a filter. Simply boiling the water at a certain temperature and calling it a day will not help because many toxins survive even in high temperatures. So, the best way to solve this issue is to get a filter.

How Often Do You Change Your Water Filter for Well Water?

The best well water filtration system for well water has several crucial parts, but perhaps the most important segment is the internal form or filter. This portion soaks up all the dirt and toxins to improve water quality.

Imagine a vacuum cleaner, and you know that after a certain period when the vacuum cleaner gets full and cannot absorb any more waste, you have to clean it. Similarly, after a particular time, the filters also get saturated with dirt, dust, and several other substances.

Whole House Water Filter

That is why you have to pay special attention to maintaining a water filter. The number of times you will have to clean the filter depends on several factors. For example, if your filter has multiple chambers, it will likely require less maintenance.

However, if your filter has one chamber and stores the sedimentation and cleans water in the same place, you will have to clean that filter regularly. Usually, you can go 3 to 6 months without cleaning the product; however, some filters need weekly cleaning.

What to Look For Before Buying?

When someone judges a product in its entirety, it’s easy to forget about individual parts. However, these different parts matter a lot, so we have gathered some of the crucial points that you must remember before purchasing a water filter from our whole house well water filtration system reviews.


Filters come in various shapes and sizes. From this well water filtration system reviews, you already saw that some filters have a large tank, while others have two or three chambers. So, at first, you have to decide where to place the filter and then see how much space you will have left.

You will find small as well as large filters in the market with ease. So, as soon as you get the accurate measurements, you can decide on the brand and size you want.


Depending on the size of your family and the number of people drinking water every day, you will have to decide which filter to get. If you get a filter that is too small, then it would have to process the water multiple times a day. That would consume more energy and also wear the product down.

Whole House Water Filter

On the other hand, if you get a big filter and have a small family, water will remain inside the container for a long time and ultimately stagnate. So, the capacity of the filter really matters. You can get filters with a capacity of 10 gallons and also get one with 95,000 gallons, so the choices are endless.


These products can be an investment because of multiple reasons. First of all, they can be expensive, and secondly, it’s a bit of work to set them up. So, if you buy the product and then it does not work for long, all your money automatically goes down the drain.

Hence you need to check the durability of these filters. Usually, heavy-duty plastic or aluminum comprises the external parts of these machines. However, if you choose a metal filter, make sure that it is stainless and has no chances of forming rust.

Internal Filter

A crucial part of these products is the internal filter. This portion is where the water processing mainly happens. As a result, it has to be top-notch and capable toof processing solid particles and chemicals. Some products have specifications of the particle sizes that their filters can capture.

So, knowing that information can help you choose. Moreover, some devices also specialize in sedimentation, while others focus on getting rid of the chemicals. You can also get filters to reduce the smell and stain from the water.


You can easily see the solid particles floating in the water and think that filtering by hand will purify it. Some people even boil the water and drink it straight. However, that is extremely dangerous because water contains millions of harmful chemicals that we cannot see with the naked eye.

But these filters do a fantastic job of getting rid of these chemicals. Be it chlorine or arsenic or even harmful bacteria, a good quality filter will be able to process the water and provide you with 99% clean water. So, always make sure to check the chemical reduction rate before buying such a device.

Solid Particles

These products also do an amazing job of separating the solid particles from water. So, if you live in a place where the water is too muddy, it will be wiser to invest in a filter specializing in sedimentation, and then you can get cleaner water at all times.


Even though these filters are responsible for cleaning the water, you have to clean these products from time to time to ensure that they do their job efficiently. The range up to which you can leave the filter without cleaning depends on the models.

However, it is better to keep an eye and change the internal filters frequently. Some models even have an indicator that tells you exactly when to change.

Whole House Water Filter Systems Installation & Maintenance

After you make the purchase, there are some steps that you have to follow before you can enjoy a clean glass of water.


This process can seem a bit daunting as you have to work with metal pipes and other stuff. But most of these models come with all the necessary parts for installation. However, one thing you should do by heart is following the user-guide.


Do not skip any part because that might affect the way the filter processes. You can also take help from professionals or YouTube to set up the product on a compatible mounting frame.


Another step where you have to pay close attention is maintenance. Every model is different, and some would need cleaning after six months, while others require a thorough wash every week. So, depending on your model, you should wash the filters.

The filters that have dual chambers can be tricky as you have to follow the same process twice. But the end result is always worth it.

Disposing of the internal filters might seem tough, but there are levers or pressure release options that easily loosen the part. So, keep your eyes open for these features, and the maintenance process will be a piece of cake.
