What a point-of-entry system actually does
A whole-home filter — the trade calls it point-of-entry, or POE — is plumbed in where the water enters your house, ahead of the water heater and every branch line. Everything downstream is treated: the kitchen tap, all the bathrooms, the laundry, the ice maker, the hose bibs. That matters more than it sounds. Chlorine and chloramine don't only affect taste; they off-gas in a hot shower, and hardness scale does its damage inside the water heater and the dishwasher long before you see it on a glass.
Why chloramine changes the specification
This is where most systems sold in Massachusetts are wrong for the house they're in. The MWRA — which supplies Boston and dozens of surrounding communities — disinfects with monochloramine rather than free chlorine. Standard granular activated carbon barely touches chloramine. Removing it takes catalytic carbon and genuine contact time, which means a properly sized tank and a flow rate matched to the house. A tank that's too small looks identical on the invoice and fails at the shower head. We size to your peak demand, and we tell you the flow rate we designed for.
Sequence is the whole job
On well water especially, a whole-home system is a train, and the order is not negotiable. Sediment comes out first or it destroys the media behind it. Iron and manganese get oxidised before they get filtered. Softening comes after oxidation, never before. Specialty media for arsenic or PFAS goes where the water is already clean enough for it to work. UV goes last, because it needs clarity to be effective. A system installed out of order can test beautifully on day one and fail within a year.
How it goes
Test first. Quote second. Install third.
In that order, every time. It is the only way to know whether you need a three-thousand-dollar system or a two-hundred-dollar one.
Free in-home water test
We measure hardness in grains per gallon, pH, chlorine or chloramine, iron and total dissolved solids at your tap, and look at your plumbing, water heater and any existing equipment. About 45 minutes, no obligation. Where it's warranted, PFAS, arsenic, radon and bacteria go to a MassDEP-certified laboratory — quoted before any sample is taken.
Straight answers, in writing
Every number read against its standard, what it means for your house, and what we'd do about it. Including the cases where the answer is that you don't need anything from us — which in MWRA communities happens often.
Installed, tested, and proven
Licensed, insured, permitted where your town requires it, and sequenced correctly: sediment, oxidation, softening, specialty media, then UV. We re-test after commissioning, because a system nobody verified is a hope rather than a treatment.

Whole-Home Filtration — common questions
Do I need a whole-home filter if I already have a pitcher filter?
A pitcher handles taste at one tap. It does nothing for the water in your shower, your washing machine, or your water heater — which is where hardness scale and chloramine actually cost you money. Most homes end up with both: a whole-home system for the house, and reverse osmosis at the kitchen sink for drinking water.
How long does installation take?
A straightforward point-of-entry install is three to five hours, and your water is off for part of it. Well systems with multiple stages take longer, and we'll tell you which one yours is before we schedule it, not on the day.
How often does the media need to be replaced?
Carbon media typically runs five to seven years depending on your water and your household's usage. Sediment pre-filters get changed far more often — quarterly to twice a year. We'll show you how to change those yourself if you'd rather not pay someone to do it.

Let's find out whether you actually need this
The in-home test is free, takes about 45 minutes, and ends with a written report — including the parts where the answer is that you don't need anything from us.
- Hardness in grains per gallon, pH, chlorine or chloramine, iron and TDS — measured at your tap.
- PFAS, arsenic, radon and bacteria through a MassDEP-certified laboratory, quoted before any sample is taken.
- Every number read against its standard, in writing, with no obligation.
