Most Common Contaminants Found in Well Water

All of this talk about purifying water brings forth the question of why we should even bother. What exactly is in our well water that makes it harmful if not filtered?

Below are some of the most common contaminants that make your water toxic:


Since the water comes from a well, it’s not uncommon for dirt, dust, and other debris to get sipped up along with the water. These particles are called sediments. That’s one of the many purposes of a system’s filters. Visible particles are trapped in a barrier and are removed from the water that gets into your home.


The iron that gets mixed up with your water is generally divided into two major types. The first one is called ferrous iron and is unseen, while the second one is called ferric iron, which comes in the color red because of rust.

The latter, being large particles, can be removed by the sediment filter along with other visible particles. However, the ferrous iron requires a process of oxidation. Basically, the iron in the water is charged with an Ion and changes it into a non-toxic substance.


Chemicals that get mixed up with your water is the result of various natural and man-made processes. These often include herbicides or pesticides used in gardening or the accumulation of arsenic substance as the water runs through the ground.

This is where filtration systems often battle it out. Although the effectiveness varies from one system to another, the use of carbon filters disinfects and purifies the water, freeing it from these chemicals.

Whole-House vs. Reverse Osmosis

Before we reach a final verdict, it’s important that we first understand what whole-house filtration systems do and how they are different from the reverse osmosis filtration systems we often see advertised.

Reverse Osmosis

Reverse osmosis is the process of filtering water that comes into a specific area in your house. More often than not, this is used on sinks to turn unfiltered water into drinkable water.

Basically, with a reverse osmosis filter, a dedicated membrane functions as a barrier to remove a wider range of contaminants in the water.

Whole-House Filtration

On the other hand, whole-house filtration functions by connecting to your main water line to filter all incoming water. To sustain this, a whole-house filtration system must be able to withstand the pressure coming from your water source. At the same time, it should also make sure that the water output is not severely compromised.

Contaminants Reduced

Because it is concentrated on a specific area of the house, reverse osmosis filtration systems can reduce more contaminants. These are equipped with a more complex series of filters working not just to disinfect but to purify your water, as well.

On the other hand, whole-house filtration systems work to keep your water clean enough that it doesn’t damage your house or your body. Furthermore, some whole-house filtration systems included reverse osmosis filters, as well.

Water Pressure

A whole-house system needs to filter all incoming water that enters your home. Because of this, they also need to be able to maintain a certain amount of pressure for your convenience.

Since whole-house systems don’t need to focus on a specific area in your home, they also take a shorter time filtering your water. This means that they have a stronger water pressure as compared to reverse osmosis filters.

Buyer’s Guide

Best Whole House Water Filter for Well Water

Looking for a whole-house water filter system is a tricky business. You have to make sure that you’re getting the best one. Otherwise, you might have to spend a few more bucks in having them replaced.

For this reason, you must know exactly what you’re looking for. Here’s a quick guide to help you with that.

Flow Rate

Flow rate is the availability of water needed for all your home components that need it. This includes your shower, kitchen, bathroom, and many more. More often than not, these components indicate their water requirements to function properly, shown as GPM or gallons per minute.

Get the sum of all of these, and your whole house water filter should be higher than all the GPMs combined to avoid interruptions in your water consumption.

Filter Size

The size of the filter greatly affects your water consumption experience. A bigger filter means it would take longer for the water to be disinfected and purified. Be that as it may, this also guarantees a faster flow rate because more water is being filtered.

The most common acceptable size of the filter is about 4.5 inches by 20 inches. However, larger houses require larger filters, as well.

Filter Life

The filter life indicates how many gallons of water the system can purify, giving an idea of how long your filters will last. This is significantly affected by the quality and quantity of the filters.

More often than not, sediment filters help the carbon blocks and make the system capable of filtering around 100,000 gallons of water. This is around a year of everyday functioning for a family of four. Anything less translates to shorter filter life.

Port Size

The port size refers to the capability of the filter system to be connected to your main water supply. The port size is often around an inch in diameter, allowing it to connect to most household pipes.

Some households use a ¾-inch pipe, but a one-inch port would still be the best option to avoid the water from bottlenecking on the connection.

What You’re Using It For

The most important thing to consider when buying a whole house water filter is its purpose. Although we might all be looking for a water filter, what we’re using it for may vary from one household to another.

For example, if you plan on using it solely for bathing or washing, you can settle for whole-house filters that maximize their flow rate. This will give you enough supply for your water consumption needs.

On the other hand, if you want a system that purifies your water and makes it drinkable, opt for filtration systems that include reverse osmosis or other processes that removes all impurities in your water.

Final Word:

The time has finally come for us to decide which is the best whole house water filter for well water on our list. As always, it depends on your personal preference, since we all have our own needs in our household. Nevertheless, keep in mind that some filtration systems are capable of covering all your needs and more.

Of all six systems we presented, we firmly believe that the Aquasure Bundle Filtration reigns superior. It’s true that all of these products have a sediment filter that removes visible particles from your water. Still, Aquasure is the only one that made sure to include a softener and a reverse osmosis filter.

This means that aside from cleaning and softening your water for household chores, you can also make sure that the water coming into your home is drinkable because of the RO filter. What makes it even more surprising is that the flow rate is not significantly affected, considering the fact that it still produces a 75 GDP output.

Like any other system, the Aquasure Bundle Filtration has its downsides, too. Its peak performance only reaches a maximum of 50,000 gallons of water, which means you might have to change filters more often compared to others.

If you’re not a huge fan of maintenance, consider getting the Aquasana Whole House Well Water Filter. This option is capable of filtering up to 500,000 gallons of water. That amounts to almost five-years of hassle-free water consumption.
