Virginia Service Areas
Select a region to see the main cities we service, local installation notes, and frequently asked questions for that area. If your city isn't listed, just share your address and we'll confirm whether installation is available.
Fairfax County
Virginia's Korean-American hub, including Annandale and Centreville
- Annandale
- Centreville
- Fairfax
- Chantilly
- Springfield
- Vienna
- Falls Church
This is our highest-volume area for Korean-community consultations and installs. It's served by Fairfax Water, with moderate-to-hard water at 5–10 gpg, so many households install a purifier and softener together.
Can a townhouse in Annandale get an installation?
Yes. If you're renting, we recommend checking with your landlord or property management first.
Loudoun · Prince William · West
Around Dulles Airport and western Northern Virginia
- Ashburn
- Herndon
- Aldie
- Dulles
- Manassas
- Amissville
- Marshall
- The Plains
Served by Loudoun Water, where a full service-line inventory confirmed no lead service lines. In the western outskirts (Marshall, The Plains), some homes rely on private wells, so we review your well-water test results together.
Do you install for homes on private wells?
Yes. Since well water quality varies home to home, share your test results or what you've noticed about taste and scale buildup, and we'll recommend the right purifier/softener combination.
Arlington · Alexandria
Bordering Washington, DC
- Arlington
- Alexandria
A dense residential area bordering DC, with a high share of condos and apartments, so we check building delivery restrictions before installation.
Do you install in high-rise condos in Arlington?
Yes. Some buildings have delivery restrictions, so please share the building name and we'll check in advance.
Richmond Area
Virginia's capital Richmond and nearby counties
- Richmond
- Henrico
- Midlothian
Served by a different water utility than Northern Virginia, so we review your local utility's annual water quality report with you before installation.
Is Richmond's water the same as Northern Virginia's?
Richmond is served by a different utility. We'll check the exact water quality in your local utility's annual water quality report.
Hampton Roads
Southeastern Virginia coastal area
- Virginia Beach
- Norfolk
- Chesapeake
- Newport News
- Yorktown
Newport News Waterworks' service area has moderate hardness at about 69 mg/L (4–6 gpg). With many new-construction homes here, inquiries for built-in and under-sink models are also rising.
Can a built-in unit be installed in new-construction homes in Yorktown?
Yes. New-construction homes tend to have standardized plumbing, which makes built-in model installation relatively straightforward.
Southern Virginia
Southern area bordering North Carolina
- Emporia
- Alberta
A southern outlying area farther from the branch. For addresses near or beyond the 70-mile radius, we'll confirm visit availability during the consultation.
Do you install in farther areas like Emporia?
If your area is serviceable, you'll get the same installation and 6-month maintenance terms. Since it's farther from the branch, visit scheduling needs to be coordinated in advance.
Installation may be difficult in areas more than 70 miles from a Coway branch or authorized dealer.
Virginia Tap Water: Northern Virginia Runs Hard
Northern Virginia tap water comes from treated Potomac River and Occoquan Reservoir water and meets federal and state standards. Fairfax Water does note, though, that its water runs moderate to hard.
U.S. Geological Survey (USGS) scale: 0–60 soft, 61–120 moderate, 121–180 hard, 181+ very hard. Fairfax Water figures reflect its published 5–10 gpg range; Newport News is the 2025 average.

Scale and White Spots
Fairfax Water explains that white spots on coffee pots and glasses come from minerals like calcium. Split the job: a purifier for drinking water, a softener for household water.
A Disinfection Method That Changes with the Seasons
Fairfax Water uses chloramine from July through March and free chlorine from April through June. If your water tastes different in spring, this is likely why.
Homes on Private Wells
Homes on private wells, such as in western Loudoun, aren't covered by public water standards. We'll recommend a purifier–softener combination based on your water test results.
These figures are system-wide data published by the agencies; actual water quality at your home may vary by water provider, season, and building plumbing. Check your local water provider's annual quality report for precise figures.

Do you install in Annandale or Centreville too?
Yes — installation is available across Fairfax County, including Annandale and Centreville, and Loudoun County, including Ashburn. For Richmond and Virginia Beach, send us your address and we'll confirm availability.
Is Northern Virginia tap water safe to drink as is?
The latest reports from Fairfax Water and Loudoun Water show tap water meeting all federal and state standards. Households usually choose a purifier for taste, disinfectant odor, or mineral content concerns.
Do I need a water softener in Northern Virginia?
Fairfax Water describes its water as moderate to hard at 5–10 gpg. If scale on kettles or shower enclosures bothers you, consider a softener alongside your purifier.
Can I install in a townhouse or apartment?
Most homes can be fitted, but renters should check with their landlord or management office first. We'll recommend the right model for your home — countertop or undersink — during your consultation.
How are filters maintained after installation?
During your rental, a Coway specialist visits every 6 months to replace filters and inspect your products. Maintenance is included in your rental fee.
