Under-Sink Water Filters in Chicago

The cleanest water in your home starts right beneath your kitchen sink.

Most Chicago homes deliver water through decades-old pipes. By the time it reaches your tap, it can carry lead, chlorine, and sediment. An under-sink filter removes those contaminants at the final point - before the water touches your glass.

ProEcoLife designs, supplies, and installs under-sink water filter systems built specifically for Chicago’s water profile. Our 9-stage PEL75 reverse osmosis system fits neatly inside your kitchen cabinet and delivers clean, mineralized water on demand – with no countertop clutter and no plumbing disruption to the rest of your home.

What Makes Our Under-Sink Systems Different

9 Filtration Stages

Most under-sink filters use 3 to 5 stages. Our PEL75 uses 9 – sediment pre-filtration, dual carbon block, a high-rejection RO membrane, mineral restoration, alkaline balancing, infrared energization, and shungite antioxidant treatment. Each stage targets a different group of contaminants or water quality issue.

Built-In Mineral Restoration

Reverse osmosis removes nearly everything – including calcium, magnesium, and potassium your body needs. Our system adds them back through a dedicated mineral and alkaline stage after the membrane. You get pure water that’s also properly mineralized and pH-balanced.

Real-Time Water Quality Display

The PEL75 includes a smart monitor that shows live TDS readings for both unfiltered and filtered water. You see your tap water quality and your treated water quality side by side – every time you use the system, not just during installation.

Fits Any Standard Chicago Kitchen

Our under-sink system is compact enough for Chicago apartment cabinets and large enough for suburban homes. Our technician surveys your cabinet space during the free water test visit and confirms the right configuration before a single part is ordered.

What an Under-Sink Filter Removes

Chicago tap water is treated - but treatment doesn't mean clean. Chlorine, residual lead from service lines, PFAS from industrial runoff, and dissolved sediment all pass through municipal treatment and enter your home.

Our under-sink RO system places a final barrier between the city supply and your glass. The 9-stage process reduces lead by up to 98%, reduces chlorine taste and odor, reduces PFAS to below EPA health advisory levels, and removes bacteria, arsenic, nitrates, and volatile organic compounds. The result is water that tests clean on every parameter – with minerals restored and pH balanced for daily drinking and cooking.

Better for Drinking and Cooking

Filtered water changes more than taste. Chlorine-free, lead-free water makes noticeably better coffee, tea, and cooked meals. Your pasta absorbs clean water. Your soups aren’t built on a chlorine base. The difference shows up in every recipe that starts with tap water.

Better for Ice and Appliances

Under-sink filters can be plumbed to your refrigerator ice maker and water dispenser. Ice made from filtered water is clearer, tastier, and free of the off-flavors that come from untreated Chicago tap. Filtered water also reduces scale buildup in kettles, espresso machines, and steam ovens.

Better Than Bottled Water

A ProEcoLife under-sink system produces cleaner water than most bottled brands – at a fraction of the long-term cost and without the plastic waste. Chicago families who switch from bottled water typically recover their system investment within the first year of use.

An under-sink filter handles Chicago's hardest water problems without changing anything visible in your kitchen - no countertop units, no pitcher, no jugs in the fridge.

Installation by Our Chicago Team

Every ProEcoLife under-sink system is installed by our certified Chicago technicians. We handle the full process in a single visit - from cabinet survey to water quality confirmation. Here's what that visit covers:

Cabinet Survey and Water Test

We measure your cabinet space, test your incoming water quality, and confirm the right system configuration before installation begins. No surprises, no return visits for parts.

Full System Installation

Our technician connects the system to your cold water supply, installs the dedicated filtered-water tap, routes tubing to your drain, and optionally connects to your refrigerator line — all in one visit.

Water Quality Verification and Walkthrough

We flush the system, run a live TDS comparison showing your tap water versus your filtered water, and walk you through the monitor display, filter schedule, and what to do if anything needs attention.

Keeping Your Under-Sink System at Peak Performance

Automatic Filter Reminders

We track your filter replacement schedule from day one. When a stage is due for replacement, we reach out and book the service visit. Your system never quietly degrades between changes.

On-Site Filter Replacement

Our Chicago technician comes to your home, replaces each filter stage correctly, and tests the output water before leaving. No DIY cartridge handling, no risk of incorrect seating, no skipped flush cycles.

RO Membrane Service

The RO membrane is the heart of the system and typically needs replacement every 2 to 3 years. We track its age, test rejection rates at each service visit, and replace it before performance drops – not after you notice a change in taste.

Same-Day Service Available

If your under-sink system shows a leak, an error on the monitor, or a sudden drop in output pressure, call us. Our Chicago team carries common parts and can often resolve issues the same day you contact us.

 Trustindex verifies that the original source of the review is Google. Pro Eco performed water testing and a well-water bacteria disinfection service at my home. They clearly explained what to expect throughout the process and were very communicative from start to finish. Their team was knowledgeable about water systems and to answer my questions. I had a very positive experience with this company. I will be calling them next year for another service.

 Trustindex verifies that the original source of the review is Google. We have been using ProEcoLife for at least 14 years. Back when we were still living in Des Plaines, we installed our first RO Water Filtration system with Karol Dołęga. We used this water for many years, and later when we moved to Mount Prospect, Pro Eco Life uninstalled, stored, and installed the system in our new home.
This is a company you can truly rely on. They remember on their own when the filters need to be replaced. They haven't disappeared from the market after all these years, and most importantly, they have truly great water.
People who come to our home ask where we get such good water. ProEcoLife water flows from every faucet, filtered through a Reverse Osmosis Water Filtration system designed and installed by ProEcoLife. That system produces water that is, first and foremost, healthy.
LOVE IT!
Recommended from the bottom of my heart to everybody!

 Trustindex verifies that the original source of the review is Google. At Anchor Express Inc., we used to spend thousands of dollars every year on bottled drinking water for our office. Aside from the cost, we were increasingly concerned about the amount of plastic waste and the potential health concerns associated with storing and consuming water from plastic bottles.

PRO ECO LIFE came in, analyzed our needs, and installed a commercial drinking water filtration system for our office. The difference has been outstanding. We now have a constant supply of clean, great-tasting drinking water for our employees without the need to purchase, store, or dispose of bottled water.

What we appreciate most is their ongoing service. Every six months, their team returns to replace filters, inspect the system, and perform preventative maintenance, ensuring everything continues to operate at peak performance.

The investment has been worth every penny. Not only are we saving money, but we have eliminated our dependence on bottled water and significantly reduced our plastic consumption. Our employees enjoy high-quality filtered water every day, and we have peace of mind knowing the system is professionally maintained.

PRO ECO LIFE has been knowledgeable, professional, responsive, and a pleasure to work with. We highly recommend them to any business or homeowner looking for a long-term water quality solution.

 Trustindex verifies that the original source of the review is Google. I have been a customer of PROECOLIFE for over 7 years, and I can honestly say they are one of the best service companies I have ever worked with.

My home is supplied by a private well with extremely challenging water conditions. The raw water contained high iron levels, arsenic, heavy metals, dissolved solids, and other contaminants. Drinking the water directly from the well was simply not an option.

The team at PROECOLIFE thoroughly analyzed my water and designed a complete treatment system tailored specifically to my property. They installed a comprehensive solution including sediment filtration, arsenic removal, iron removal, water softening, whole-house reverse osmosis, UV sterilization, pH correction, a booster pump system, and a dedicated drinking water RO system in the kitchen.

The results have been nothing short of incredible. After installation, I had my water independently tested by a private laboratory. The lab technicians told me they rarely see drinking water this clean and this pure. My whole-house RO system consistently produces approximately 4 ppm TDS water, while my kitchen drinking water system produces approximately 1–2 ppm TDS water. The quality is outstanding.

What truly separates PROECOLIFE from other companies is their customer service. Karol, Maciej, and Konrad are top-quality professionals who genuinely care about their customers and take pride in their work. Mrs. Sylwia in customer service is always professional, responsive, knowledgeable, and a pleasure to work with.

Over the last seven years, whenever there was an issue or downtime, PROECOLIFE responded immediately. In many cases, they had a technician at my house within 30 minutes to diagnose and resolve the problem. That level of support is almost unheard of today.

Thanks to PROECOLIFE, my family has clean, safe, healthy drinking water every day. Their technical knowledge, professionalism, responsiveness, and commitment to customer satisfaction are second to none.

I would recommend PROECOLIFE without hesitation to anyone looking for water treatment, filtration, reverse osmosis, arsenic removal, or well water solutions.

Thank you to the entire PROECOLIFE team for your outstanding work and continued support over the years!

 Trustindex verifies that the original source of the review is Google. Zainwestowałem w system ProEcoLife (filtr na cały dom + RO w kuchni) i jestem w 100% zadowolony. Woda smakuje świetnie, a instalacja działa bez zarzutu. Chciałbym jednak szczególnie wyróżnić obsługę klienta. W trakcie codziennego użytkowania, gdy tylko potrzebowałem wsparcia, szybkiej porady lub miałem jakiekolwiek pytania techniczne, firma stawała na wysokości zadania. Pełen profesjonalizm i dbałość o klienta na każdym etapie. Gorąco polecam!

 Trustindex verifies that the original source of the review is Google. Just swapped out our old water filter for the PEL75. It actually makes a noticeable difference in how our tap water tastes, and it’s great for brewing coffee or tea without that weird chlorine aftertaste. Professionally installed, very friendly and knowledgeable service. Definitely recommend & worth it.
