Water filtration in Apex, North Carolina

Apex sits on the same side of the Triangle as Cary and Morrisville and shares most of their water questions. What is different here is the housing and the edges of town.

Much of Apex is newer construction, which takes lead plumbing largely off the table and makes taste, smell and drinking water quality the real conversation. Head far enough southwest and you are into Chatham County, where properties on private wells are a different problem entirely.

What the water is like here

Apex is on municipal surface water, like most of western Wake County.

That puts the same two drinking-water questions on the table as elsewhere on this side of the Triangle: 1,4-dioxane and PFAS. Neither is removed well by conventional municipal treatment. For 1,4-dioxane, reverse osmosis is the practical household-level option. For PFAS, reverse osmosis is the treatment type most commonly used for PFAS at home. If PFAS is your concern, look for a unit certified to NSF/ANSI 53 or 58 for PFAS reduction.

For the whole house, the everyday issue is the chlorine that surface water requires. Carbon filtration handles that, and it is the less expensive half of the answer.

What we actually find in Apex

Drinking water versus whole-house water

These are two different jobs. Whole-home filtration handles chlorine, sediment and smell everywhere. Reverse osmosis handles dissolved solids and lead at one tap. On municipal surface water, most homes end up wanting both.

Newer homes, different problems

A house built in the last twenty years is unlikely to have lead solder or lead service lines. That removes one concern and leaves the ones treatment cannot address.

Properties on the Chatham edge

Southwest of town, private wells become common. Wells are a completely different build: iron, sulfur, sediment and low pH rather than chlorine. If you are on a well, start with the well water systems.

Questions we get in Apex

What’s the difference between whole-home filtration and reverse osmosis?

Whole-home treats every drop entering the house — showers, laundry, dishwasher, ice maker. Reverse osmosis treats a small volume very thoroughly at one tap, usually the kitchen sink, for drinking and cooking. They’re complements, not competitors. Whole-home handles chlorine, sediment, iron and smell. RO handles dissolved solids and lead at the tap you drink from. That’s why every whole-home system we sell includes an RO system free.

What’s the difference between a water softener and a water filter?

Different jobs. A softener uses resin and salt to remove calcium and magnesium — the minerals that cause scale, spotting and that film on your skin. A filter uses carbon or specialty media to remove chlorine, taste, odor and other contaminants. Softening doesn’t clean your water; filtering doesn’t soften it. Most Triangle city homes need filtering more than softening. Well homes often need both, plus more.

Is the water test really free?

Yes. We come to your home, test at your kitchen sink, and show you the results while we're standing there. No fee, no obligation, no PDF emailed to you three days later. It takes about fifteen minutes.

How long does installation take?

Most whole-home systems are a half day. A reverse osmosis drinking system under the sink is usually two to three hours. If you need both, plan on one full day.
