Cost of Whole Home Water Filter
The cost of water purification systems depends on whether you need a point-of-use system (like a reverse osmosis filter) or a whole-home filtration setup. Factors like home size, water testing results, and filtration technology (carbon, RO, UV) all affect pricing. We offer free water testing and upfront pricing with no hidden fees.

Customer Reviews
“I am writing this to complement Carini and the Technician Conner that just concluded the annual service on my Heater and A/C Unit. The visit was professional and left my home as clean as when it started. I usually do not write reviews for jobs done unless it was above expectations and this visit was that. My wife and I are very happy not only because the systems have no problem but the services provided that were above and beyond my expectations. Thanks”
-Raymond
“I had a great experience with Carini Home Services for my new HVAC. Anthony provided all the information on the product in great detail and clear language and was very thorough and complete. This made it easy for me to select the right product. Alvin and Victor installed the unit on my roof. They were fast and efficient. They used an equipment lift to raise the unit to roof level. No crane needed, which reduced overall cost. All staff showed pride in their work. I would highly recommend Carini for HVAC installation.”
-Afra
“Carini Home Services goes above and beyond. We got many quotes from various companies and Carini Home Services was very knowledgeable and the only one that checked back in and told us about current and new rebates that were available. Because of this we decided to go with them when we were ready to install a mini-split for our space. They are very professional, efficient, clean, and helpful. They stay on top of everything, even after install. I cannot recommend them enough, especially our sales rep Anthony DeCarolis. If you are considering any home services, call Anthony at Carini today!”
“Carini has serviced the home we’re renting a couple of times. Great service, very considerate and professional. Eddie helped get the WiFi thermostat system working and resolved the issue very quickly. Thank you Eddie. Appreciate the technical and quick service.”
