One of the easiest ways to live a blissful life is to make responsible choices regarding what you drink and eat. Truly, you are what you eat. Likewise, access to clean and filtered water is one of our fundamental requirements, and installing a whole house water filter ensures this is achieved.

Water filtration is essential to prevent water-borne diseases and illnesses. Moreover, whole house water filters improve indoor air quality and promote better day-to-day health.

The bad news, unless your water supply is from a well 800 feet or more below the ground, there is a big question mark on the quality of your water.

Does this mean you need a whole house water filter? And is the investment worth it? By the end of this guide, you will know.

So, here is our guide answering the question, are whole house water filters worth it?


  • Depending on your water conditions and the particular filter model you are considering, a whole house water filtration system can very well be worth the investment.
  • Make sure by having your water tested for pollutants and other parameters. Then, base your purchase decision on the findings.

Do You Really Need a Whole House Water Filter System?

Everyone who is struggling with tainted, turbid, and contaminated water would probably do good installing a water filtration system.

Not only does filtered water boost the immune system, especially for kids and aged people, when treated right it’s also free from chlorine and other contaminants which can cause unpleasant taste and odor.

But my water supply has been treated alright!

Sorry to be the bearer of bad news, but your city water supplier is doing just the bare minimum to pass the EPA’s standards[1]. And to be honest, the EPA doesn’t have very high standards to begin with. It is perfectly okay with certain levels of arsenic and lead, etc.

Besides, the water that leaves the source has to make a long journey before it can reach your tap. What goes on in between is another question mark on its quality.

By far, installing whole house water filtration systems offers a more environmentally friendly solution to cleaner water. This is because you no longer have to spend money on bottled water that simply adds to pollution.

Of course, the answer to whether you really need a whole house treatment system lies in your water quality itself. Don’t judge by its looks, it can be deceiving!

We suggest getting an at-home water test kit or sending a sample to the laboratory for a detailed analysis. The real question is: what’s in your water?
