About Us

Greenlight Water & Air Enhancements has proven to provide quality but cost-effective environmental water treatment to everyday hard-working families and businesses in the Baltimore-Washington and Western Maryland areas.

We solve well and municipal water issues by providing and ensuring outstanding customer service and making every effort not to create reoccurring service, unlike most water treatment companies existing today, where the goal is to service the customer a minimum of every two to three years. (About an average ticket of $480 with service charge included just for a standard carbon rebed which they claim last for three years at most.)

This is why one of our featured environmental products is our Entek KDF/Carbon filter, which is outstandingly compatible with our Entek Limited Lifetime Warranty Conditioner, which certainly minimizes service tremendously. This is why two-thirds of our customer base is families who had pre-existing water treatment that they were not satisfied with.

You see, our representatives have found out in their 22 years of experience that if we used more quality sacrificial media at the original installation of our product, we could minimize reoccurring service, and the customer could be fully satisfied with the quality of their water with a lot less maintenance no matter how long you’ve benefitted from the product. Not to mention new customers deciding on filtration for their water for the very first time, making Entek their first and only choice.

Allow us to come out to give you a complimentary water and air examination with no obligation. Let us show you how to change the quality of life in your home by enhancing the quality of your water and air. Let us also show unsatisfied pre-existing water treatment families how much more they could save with Greenlight Water & Air Enhancements backing our Entek line of products 100%.

We serve the State of Maryland with pride. Including but not limited to Carroll County, Frederick County, Washington County, Baltimore County, Harford County, Cecil County, Montgomery County, Howard County, parts of Prince George’s County, and parts of Charles County.
