Water Filtration Systems Explained

We have both whole-house and point-of-use water filtration systems in our home. Is it worth it? Here’s what to consider.

Benefits of a Whole-House Water Filtration System

Improved Water Quality

A properly selected whole-house system can reduce sediment, chlorine, and certain other contaminants, depending on the type of filter installed. Many homeowners notice improvements in taste, odor, and clarity. (Not all systems remove everything. The filter type matters.)

Skin & Hair

This is something I personally notice. When our shower filters need replacing, I can tell immediately that my hair feels drier and tangles more easily. Reducing chlorine and sediment can make a noticeable difference for some people.

Appliance Protection

Filtering sediment and mineral buildup can help extend the life of:

• Water heaters

• Washing machines

• Dishwashers

• Faucets and fixtures

Less buildup = less wear over time.

Reducing Bottled Water

If you’re buying bottled water regularly, a filtration system can help you reduce that habit, which is better for your health, your budget, and the environment.

Types of Systems: There are two main categories:

Point-of-Entry (POE)

Installed at the main water line entering your home. These filter all the water used throughout the house, including showers and appliances. We’ve had a POE system installed by our plumber for years. He recommended Aquacrest. 

Point-of-use (POU) 

POU systems are installed at individual fixtures, such as under the kitchen and bathroom sinks, and attached to shower heads and the bathtub. We use Aquacrest Under Sink Water Filter under our kitchen and bathroom sinks, and AquaBliss on shower heads.

For the bathtub, there are Filtration Balls you place on the spout. They’re worth considering if you take many baths.

POUs are easy to maintain and replace. Above, Alex is replacing the filter in the kids’ bathroom.

What to Consider Before Installing

Before choosing a system, it is recommended (we didn’t do any of it; we just went with what the plumber suggested):

• Test your water first. Know what you’re trying to filter.

• Understand your water source. Municipal water and well water have different needs.

• Choose the right filtration type. Carbon filters, sediment filters, reverse osmosis, and UV all serve different purposes.

• Hire a qualified plumber for whole-house installation.

Final Thoughts

Most municipal water in Massachusetts meets safety standards. A filtration system isn’t necessarily about safety; it’s about preference, added protection, and comfort. For us, it’s a worthwhile upgrade.
