High Purity Drinking Water Systems — Maryland, WV, VA & PA
Most reverse osmosis systems sold today are built to produce a lot of water fast — 50 to 100 gallons per day — not to produce the highest purity water. Depending on what's in your water, a high-volume system may only remove a small amount of certain contaminants, like nitrate, because it processes water too quickly for the membrane to do its job well.
A 100 GPD system fills its storage tank almost immediately with lower-quality water — the "treated" water isn't much better than what went in. Our standard system is a high purity 5-stage, 24 gallon per day RO system that fills the tank at about a gallon of true high-purity water per hour. Think about how much drinking and cooking water your household actually uses in a day — it's rarely 50 to 100 gallons.
We install a high purity 5-stage RO system with a 24 gallon per day membrane and a standard 3.2 gallon pure water holding tank (larger tanks available), typically installed under the kitchen sink or in an unfinished basement. Unless you're purifying city water, most well water customers need some form of pretreatment first to protect the membrane and get the longest life out of the system.
A single drinking water faucet is usually installed at the kitchen sink, and a line can also be run to a refrigerator's ice maker or cold water dispenser. For every gallon of treated water produced, roughly three gallons of reject water go down the drain — which is why whole-house RO isn't practical, and why pure RO water is aggressive enough that it isn't used to feed a whole home's plumbing.
RO systems work more efficiently with higher incoming water pressure — higher pressure means more water production and typically purer water, because the membrane performs better.
A 100 GPD system processes water faster, which can significantly lower the rejection rate of contaminants compared to a 50 or 24 GPD system — some high-volume systems reject as little as 35-40% of certain contaminants.
A 24 GPD system paired with a larger size (optional) holding tank provides roughly 6-8 gallons of high-purity water over the course of a day — plenty for most households or small offices, prioritizing purity over sheer volume.
Modern RO systems, properly installed and sized, are highly reliable and increasingly popular with well water homeowners looking to remove nitrates, lead, pesticides, and herbicides. Service intervals depend on your pre-filtration, annual water usage, rejection rate, and total dissolved solids — but as a general rule:
An RO system installed under your kitchen sink gives you bottle-quality drinking water on demand — without the plastic waste or ongoing cost of buying bottled water.
Well water in Central Maryland, the Eastern Panhandle of West Virginia, and surrounding areas commonly contains elevated levels of nitrates, iron, hardness minerals, and in some cases bacteria. A water softener handles hardness and iron, and a UV light handles bacteria — an RO system is the final line of defense for the cleanest possible drinking water at your kitchen tap.
Most of our well water customers add an RO system after already having a softener or iron filter installed. The pre-treatment protects the RO membrane and ensures the system performs at its best for years.
Yes — a properly functioning RO membrane removes approximately 85-92% of fluoride from drinking water.
Yes — RO is one of the most effective methods for reducing PFAS compounds in drinking water.
If you're on well water with iron or hardness, yes. Hard water and iron will foul the membrane prematurely and reduce the system's effectiveness and lifespan. We always evaluate your water before recommending a system.
Yes — in most cases we can run a line from the RO system to your refrigerator for filtered ice and cold water.
Filters typically need changing every 1-2 years. The membrane lasts 4-5 years under normal conditions. We keep parts in stock and can service your system quickly.
Yes — in a good way. Most customers notice immediately that the water tastes cleaner and fresher than tap or even many bottled waters.
