Choosing the Right Water Filtration System for Your Home

Wouldn’t it be great if the water coming from the faucets in your home were guaranteed to be of the highest possible quality? Unfortunately, this is simply not the case. While those using private water sources should certainly have their water tested and treated as needed, the fact is that even water coming from the civic supply may benefit greatly from running through a residential water filtration system.

When you invest in a water filtration system, of course, you want to be sure that you are investing wisely. There are many different types of water filtration systems to choose from. While you don’t want to overspend on functionality that you don’t need, you also don’t want to sell your water filtration system short. You can begin to narrow down your options by deciding if you want a whole-house water purifier, or an under the sink, point of use system.

  • Under the sink (POU) water filtration systems purify only the water coming from that one particular faucet. That is why point of use filters are often called drinking water systems.


If you don’t have very serious issues with water quality in your home, but just want cleaner, better tasting water for drinking straight from the sink, then a point of use system will probably suffice. They are, of course, less expensive than whole-house options, but do require professional installation and service.


  • Whole-house water filtration systems are much more comprehensive in their operation, and are recommended if the quality of your water is causing issues throughout the house in a variety of applications. You wouldn’t use one just to make your drinking water taste better.


If, for instance, your laundry doesn’t feel fresh due to low water quality in the washer, or if showering in your water causes skin irritation, using the right whole-house water filtration can make all the difference. We install various whole-house solutions, including specialty cartridges, basic whole-house filters, and reverse osmosis systems. We can even help you eliminate hard water with a whole-house water softener.

  • Francis from Nicholson Plumbing and Heating was excellent. He was here to evaluate HVAC in our home. He was very patient and answered all my questions. He is also polite and easy to communicate with him. He explained technical concepts to me in layperson terms!

  • Nicholson offered what is possibly the best customer service I have dealt with in a home repair situation.  I called them because I was looking to replace my very old furnace.  They came out to do an initial estimate, and then came back when I had some further questions about my options.  After installing the furnace, they ran into some problems with my air ducts.  This happened on a Friday, and the problem was fixed by Monday afternoon.  In addition to their excellent service, they did quality work at a fair price.  I would recommend them to anyone looking for an HVAC company in the Framingham area!

  • Recently used these guys because my HVAC unit AC wasn’t working (first hot day of summer).  Showed up on time, wore booties, fixed the unit.  During the visit we talked about how my unit was having problems in the winter – which was resulting in NSTAR service calls of maybe 3-4 times per season (I am on a service plan with them).   He was the first guy to tell me WHY the problem was happening, and HOW to fix it.  I find it strange that all of the NSTAR guys etc. no one took time to point out how to fix the source of the problem…Very professional, smart.  I would use them again, and plan to for the fix on my heating unit!
