Water Filtration Systems in Annapolis & Anne Arundel County
Heidler Plumbing has been installing and maintaining water filtration systems throughout Annapolis and Anne Arundel County for over 75 years. We understand the unique water quality challenges facing homeowners in our region and provide custom filtration solutions that improve water safety, taste, and protection for your entire home.
Why Annapolis Homeowners Choose Water Filtration Systems
Water quality in Annapolis and Anne Arundel County varies significantly depending on whether you're connected to city water or rely on a private well. City water is treated by Anne Arundel County's Department of Public Works and meets EPA standards, but many homeowners still experience issues with chlorine taste and odor, sediment, and trace contaminants. Well water users face additional concerns including iron, manganese, hardness, and potential bacteria.
A quality water filtration system protects your family's health, extends the life of your appliances, and improves water taste and clarity.

Water Filtration System Types We Install
**Whole-home filtration systems** install a single filtration system that protects all water outlets in your Annapolis home. Whole-home systems use carbon filters, sand filters, or sediment filters to remove contaminants before water reaches your pipes.
**Reverse osmosis systems** deliver superior drinking water quality — reverse osmosis removes up to 99% of dissolved solids, providing clean, pure drinking water at your kitchen sink. It's a popular choice for Annapolis families concerned about lead or other heavy metals. **Carbon filtration** uses activated carbon filters to effectively remove chlorine, odor, taste issues, and some organic compounds, and works well for homes with city water looking for improved taste without additional hardness removal.
Many Anne Arundel County homes benefit from both a water softener (for hard water minerals) and a filtration system (for contaminants). We can design a complete water treatment solution tailored to your water test results.

Know the warning signs
When to Call for Water Filtration Systems
Chlorine Taste or Smell From the Tap
County-treated water meets EPA standards but often carries a chlorine taste and odor. Carbon filtration removes it without changing anything else.
Rust or Orange Staining on Fixtures
Iron and manganese are common in Anne Arundel well water. They stain sinks, tubs, and laundry, and they only get worse untreated.
Sediment or Cloudy Water
Grit in an aerator or cloudy water at the tap means particulate is getting through to your fixtures — and into your appliances.
You're on a Private Well
Well water users face additional concerns including iron, manganese, hardness, and potential bacteria that municipal treatment would otherwise handle.

Service After the Sale
Filters need changing and systems need tuning. We provide full-service support, not just an installation invoice.

Questions?
Water Filtration Systems FAQs
Do I need filtration if I'm on Anne Arundel County water?
City water is treated by Anne Arundel County's Department of Public Works and meets EPA standards, but many homeowners still experience chlorine taste and odor, sediment, and trace contaminants. Filtration is about taste, clarity, and appliance protection rather than basic safety in that case.
What's different about well water here?
Well water users face additional concerns including iron, manganese, hardness, and potential bacteria — issues municipal treatment would otherwise handle. That's why a water test matters even more for well homes.
How much do reverse osmosis systems actually remove?
Reverse osmosis removes up to 99% of dissolved solids, providing clean, pure drinking water at your kitchen sink. It's a popular choice for Annapolis families concerned about lead or other heavy metals.
Do I need a softener, a filter, or both?
Many Anne Arundel County homes benefit from both — a softener for hard water minerals and a filtration system for contaminants. They solve different problems. We can design a complete water treatment solution tailored to your water test results.
How often do filters need replacing?
It depends on the system type and your water's contaminant load, which is one more reason the initial test matters. We handle filter replacement and maintenance on an ongoing schedule so you don't have to track it.
Which areas do you serve?
We serve Annapolis, Arnold, Bowie, Crofton, Edgewater, Gambrills, Glen Burnie, Millersville, Odenton, Pasadena, Severn, Severna Park, Stevensville, and surrounding Anne Arundel County communities.
