Our Water Filtration Solutions
We recommend water quality testing as an initial step so you understand the specific challenges you face. You should also schedule testing once a year, as water quality can change over time. Our team provides services and systems for homes with well systems and those connected to municipal water. Annual testing is crucial for homes with wells, and it’s also highly recommended for homes with municipal water.
Our team designs and implements both POU and POE water filtration systems in PA, MD, and WV. POU systems provide clean and/or soft water to one or several taps in a home. POE systems function between the main water line and the rest of the home’s plumbing. That allows them to provide cleaner water from every fixture throughout the house.
Water purifiers for the home range from single-stage to complex multi-stage filtration. Many systems have an inexpensive prefilter that traps the largest particles and preserves the more expensive filter media. Often, a sediment filter provides the primary mechanical filtration. Its absolute pore size dictates the fineness of the particles it can filter. These systems will often have activated carbon for the adsorption of chemicals and gases. More advanced systems will also have an ultraviolet lamp for the neutralization of bacteria, viruses, and other pathogens.
If hard water is a concern within the context of your drinking water, we’ll often recommend reverse osmosis (RO) for water treatment. An RO system is a type of POU water filter that can remove over 99% of all substances from your drinking water.
If the concern is your home’s plumbing, we’ll recommend a POE water softener. These systems exchange calcium and magnesium in your water with salt, such as sodium chloride. We offer single-tank systems that go offline overnight to recharge. You also have the option of a dual-tank system that never has to go offline.
Water softeners and water filters in WV, PA, and MD require regular maintenance. We recommend an annual appointment, through which we can inspect the equipment, clean it, and correct any normal wear and tear. We’ll also swap out your old filter media with new products.
Our team is available for water treatment repair as well. Some of the common repairs we perform include clearing clogs, replacing ball bearings, and updating software.

Water Filtration FAQs
Here are answers to a couple of the most common questions about water filtration in PA, MD, and WV. Contact us at your convenience for further details and with any additional questions.
What Type Of Water Filter Is Best For My Home?
There are many options, and we recommend an in-home consultation to determine which is best for your household and budget. Compact POU solutions tend to be less expensive initially. Some of these solutions, such as RO systems, can deliver clean water to multiple taps. Whole-home water filters cost more up front but often save money over the life of the system.
How Often Should I Replace My Water Filter?
The frequency at which you should replace your water filter depends on the filter media and how much you use it. A basic POU water filter in WV, PA, and MD may require replacement every several months or even sooner. The main sediment filters in whole-house water purifiers, on the other hand, usually only need replacement once a year. If you remain unsure about your filter, we recommend scheduling an inspection and consultation with us.
