Why RO Makes Sense in Excelsior

Outside the documented East Metro PFAS plume but extremely hard at 18 gpg.

What Reverse Osmosis Removes

RO pushes water through a microscopic membrane that filters out almost everything dissolved in your water. Here is what you stop drinking after RO is installed.

Chlorine and chlorine byproducts

Improves taste and removes the disinfectant residue from municipal treatment.

Dissolved metals

Lead, copper, iron — particularly relevant in homes with aging plumbing.

Fluoride

Removed by the RO membrane. Households who want non-fluoridated drinking water get it.

PFAS

With a PFAS-rated membrane or pre-filter, RO removes PFAS at point of use. We install certified systems.

Sodium from softener

If you have a water softener, RO removes the sodium that ion-exchange adds. Good for low-sodium households.

Total dissolved solids

The overall mineral content drops significantly, leaving water cleaner than most bottled water.

Under-Sink vs Whole-Home RO: Which Fits Excelsior?

For most Excelsior homes, under-sink RO at the kitchen tap is the right answer. Here is why, and when whole-home RO makes sense instead.

Under-Sink RO (most homes)

Installed under your kitchen sink with a dedicated faucet, plus optional fridge water/ice line connection.

Best for:

  • • Drinking and cooking water (the exposure that matters most)
  • • Filtered ice and refrigerator water
  • • Budget-conscious installs
  • • Households not in the PFAS plume

Whole-Home RO

A large-capacity RO system installed on the main water line. Treats all water entering the home.

Best for:

  • • Severe water quality issues across the home
  • • Specific medical conditions requiring extra-clean water
  • • Households where bathing exposure also matters
  • • Larger upfront investment but higher coverage

Excelsior Reverse Osmosis FAQs

Why install reverse osmosis in Excelsior?
Even with a water softener, Excelsior's 18 gpg municipal water still carries chlorine, dissolved metals, and trace contaminants at the kitchen tap. Reverse osmosis at the kitchen sink delivers genuinely clean drinking and cooking water without the cost of bottled.
What does reverse osmosis remove from Excelsior water?
An RO system removes nearly all dissolved contaminants: chlorine and chlorine byproducts, dissolved metals (lead, copper, iron), fluoride, sodium left over from softening, dissolved minerals, and certified PFAS (with a PFAS-rated membrane or pre-filter). What is left is water cleaner than most bottled water.
Should I install under-sink RO or whole-home RO in Excelsior?
For most Excelsior homes, under-sink RO at the kitchen tap is the right answer. It serves drinking and cooking — the water where contaminant exposure matters most. Whole-home RO is significantly more expensive and is usually reserved for households with severe water quality issues. We help you decide based on your specific water test.
How long does an under-sink RO system last in Excelsior?
Sediment and carbon pre-filters typically need replacement every 6 to 12 months. The RO membrane itself lasts 2 to 5 years depending on incoming water quality. Excelsior's 18 gpg hardness means installing the RO downstream of your water softener significantly extends membrane life. Our maintenance plans include scheduled filter swaps.
Does A.J. Alberts install RO systems same-day in Excelsior?
Under-sink RO installs typically take a half-day. Many Excelsior appointments are completed same-day or within a few business days of the free water test. Call 651-738-0580 to schedule.
