Customer Testimonials
“Everyone from our initial inquiry call with Serena to Matt (our Project manager) to the technicians and plumbers that installed our system were great. They showed up on time, answered all our questions and complete our installation to deliver us clean, great tasting water, right from a dedicated kitchen tap and fridge. Thanks Angel team!”

Farasat K.
“Got a Reverse Osmosis system by Angel last year and had our first service appointment today. System has been working great, water tastes great and had to fool with the system exactly zero times since initial install. More money than doing it yourself, but save yourself the hassle and just enjoy good drinking water without ever having to buy bottled water since you’re making it at home!”

Matt S.
“Save your time and sanity. Just hire these guys. I thought about hiring a plumber and picking out a system to cut cost but playing guessing games or mix got old real fast. They were in and out in about an hour. System is up and running flawlessly and I have the comfort of quality and a warranty.”

Frequently Asked Questions

What does a reverse osmosis system do?
A reverse osmosis water filter removes a wide range of contaminants from water before sending it to the water-using appliances in a home. The best RO systems also add good minerals to the water after filtering out the bad ones. This process makes the water cleaner and healthier and improves its smell and taste.
How does a reverse osmosis system work?
A typical RO system contains four different filters that work together to clean the water. When the water enters the system, it first goes through a sediment filter, which removes any large particles from the water. After this, it goes through a pre-carbon filter, which takes out chlorine and any other organic compounds that may damage the RO membrane.
Once this initial filtration is complete, the water is ready to undergo reverse osmosis. This process works by forcing the water through a semipermeable membrane. The membrane allows water through but keeps the contaminants from coming with it.
The water then goes through one final carbon filter, which further reduces any impurities that could make the water taste or smell bad. Some systems end here and then send the water to the home. The best systems also add nutritious minerals into the water to send the healthiest, cleanest water to your tap.
Is an RO system worth it?
Yes! A quality reverse osmosis system is a worthwhile investment because of the incredible amount of toxins it can protect you from. Here’s just a small sample from that list:
- Arsenic
- Chromium-6
- Cyanide
- Fluoride
- Haloacetic Acids
- Lead
- Manganese
- Mercury
- Nitrates
- Total Trihalomethanes
- Volatile Organic Compounds (VOCs)
- Zinc
The key is to make sure you’re getting a quality system. The cheaper systems you find at big box stores don’t protect from as many pollutants as the higher-priced systems from quality brands like EcoWater. These systems also don’t produce as much water and require more maintenance than their NSF/ANSI 58 certified counterparts.
Another reason an RO system’s worth it is the money you’ll save in the long run. Most Chicagoland residents spend a fortune on bottled water because they don’t trust their tap water. Reverse osmosis makes your tap water safe to drink, thus making buying all those plastic bottles unnecessary!
How does RO compare to other filtration options?
Reverse osmosis systems provide the most complete protection from contaminants of any filtration option on the market. Standard carbon filters can remove toxins like lead and chlorine but can’t remove chromium-6 or arsenic. Distillation filters can remove minerals and chemicals but can’t remove chlorine or VOCs. UV filters take out microorganisms but not chemicals. Only reverse osmosis filters can remove all of these pollutants with no exceptions.
How much does an RO filter cost?
You can get a lower quality RO system for a little as $200. However, this system will likely cost you a lot more in maintenance and repair fees over the years.
A better option is to invest in a high-quality system and have it professionally installed. The significant upfront cost will be more than worth it for the long-term benefits and lower maintenance fees on your system.
