How Does Reverse Osmosis
Water Filtration Work?

Reverse osmosis uses water line pressure to push your household water through a semi-permeable membrane. Clean water passes through to your sink for drinking and cooking, while dissolved solids and contaminants are repelled and flushed away.

01

Water Enters Under Pressure

Your water line pressure pushes household water into the reverse osmosis system - no chemicals required for this core filtration step.

02

Membrane Filtration Begins

Water is forced through a semi-permeable RO membrane that blocks dissolved solids and unwanted contaminants, while letting purified water pass.

03

Contaminants Are Flushed Away

Dissolved solids and impurities that can’t pass the membrane are repelled and flushed away as part of the filtration process.

04

Clean Water Reaches Your Faucet

Purified water is ready for drinking and cooking right at your faucet - clearer, cleaner, better-tasting water for ice, beverages, and food.

Do I Need a Whole Home Reverse Osmosis
Water Filtration System?

Whole house reverse osmosis is rarely necessary unless your water test reveals critical issues like high nitrates, heavy metals, arsenic, or excessive Total Dissolved Solids (TDS). However, when these severe contaminants are present, a total-home purification system is the most reliable way to protect your plumbing, appliances, and health.

If your home requires a whole house RO solution, we can help! Getting the system sized correctly is essential for optimal efficiency, water pressure, and long-term performance and every property has unique water demands. Contact our team today for a free water test and consultation, and we'll help you design a system tailored to your exact needs.

Reverse Osmosis FAQs

Common questions about whole-house RO systems - answered honestly.

What makes whole house RO different from under-the-sink RO?

  • Under-sink reverse osmosis systems purify drinking and cooking water only - just the water coming out of your kitchen sink.
  • Whole-house RO treats water at the point of entry, so every water source - shower, laundry, dishwasher, toilet- gets purified water. This is essential when contaminants like arsenic or high nitrates are present throughout your home's water supply.

Is it true that reverse osmosis systems waste water?

This was a concern in the past, but modern high-efficiency RO systems have greatly improved, often achieving a 2:1 ratio or better. While some water is used in the purification process, the trade-off is exceptionally clean - and much safer - drinking water.

We'll walk you through the efficiency rating of your recommended system and help you understand what to expect for your household's usage.

Does a reverse osmosis system require electricity to run?

Most reverse osmosis systems do not require electricity to operate - they rely on your home's existing water pressure to push water through the filtration membranes. However, if your water pressure is low or you choose a system with a booster pump or UV purification stage, electricity may be needed.

Some systems also include an electric permeate pump to improve efficiency and reduce wastewater. We'll help you choose the right system for your home's specific pressure and needs.

How often do filters need to be replaced?

  • Pre-filters typically need replacement every 6–12 months.
  • The RO membrane every 2–3 years.
  • Post-filters should be replaced annually.

Sediment and water chemistry can affect these timelines. We track your system and contact you proactively when service is due - no guesswork required.

What contaminants does a reverse osmosis system remove?

A reverse osmosis system removes a wide range of dissolved contaminants, including arsenic, nitrates, lead, fluoride, TDS (total dissolved solids), hardness minerals, chlorine, chloramines, heavy metals, and many other impurities. It works by forcing water through a semi-permeable membrane that blocks up to 99% of dissolved particles.

Based on your water test results, we'll identify exactly which contaminants your specific system is designed to target.

Does reverse osmosis remove essential minerals from drinking water?

Yes, reverse osmosis does remove a broad spectrum of dissolved substances, including some beneficial minerals like calcium and magnesium. However, the minerals found in tap water contribute very little to your daily nutritional need - most of those will come from your food.

If mineral retention is a priority, we can add a remineralization filter stage to your reverse osmosis system that reintroduces healthy minerals after filtration, giving you clean, great-tasting water without sacrificing nutritional balance.

What Our Neighbors Are Saying

Real reviews from homeowners across multiple Eastern Pennsylvania counties.

“They came in and installed a water softener, reverse osmosis system and a water neutralizer. I am very happy with the results. They were very professional and courteous. I no longer have to buy bottled water and my clothes come out softer and cleaner. Having my pipes corrode is one less thing I have to be concerned about.”

“We recently had EPA install a water softener, reverse osmosis, carbon filter and UV disinfection system in our newly constructed townhome. Everyone was professional and a pleasure to work with. Work was completed when promised and we can definitely tell a difference in our water quality. I highly recommend these folks if you need anything related to your water.”
