Why are your prices so low compared to other quotes I've received?

We don't have the bloated overhead. The big in-home water companies bake the cost of "free water tests," door-to-door reps, three-hour living-room presentations, and stacked sales commissions into every quote - often $3,000 to $6,000 of pure markup. We skip all of that. Same tier of equipment, licensed Georgia install, real warranty - just without paying for someone else's pressure-sales theater.

Do I need a water softener in Georgia?

Most of Georgia has moderately hard to hard water depending on your municipality and whether you're on well water. A softener protects plumbing, water heaters, and appliances from scale, and dramatically improves skin, hair, and laundry. Use our Georgia Water Lookup to check your area.

What is the difference between a water softener and a whole house filter?

A softener removes hardness minerals (calcium and magnesium) that cause scale. A whole-house carbon filter removes chlorine, chloramines, taste and odor compounds. Reverse osmosis at the kitchen sink removes dissolved solids for drinking water. Most Georgia homes benefit from all three.

Where in Georgia do you install water filtration systems?

Our main service areas include Atlanta, Alpharetta, Roswell, Johns Creek, Cumming, Suwanee, Buford, Lawrenceville, Dacula, Gainesville, Hoschton, Braselton, Jefferson, and Winder - plus the greater Atlanta area and North Georgia.

Do I Need Reverse Osmosis If I Already Have a Whole-Home Filter?

By Grant, Honest Water of Georgia · Published 2026-06-06 · 6 min read

This is one of the most common questions we get, and the honest answer is "usually yes, and here is why."

The two systems do different levels of work

A whole-home filter, typically carbon, treats every drop of water entering your house.

It reduces chlorine and chloramine, improves taste and smell, and reduces some disinfection byproducts.

That is great for showers, laundry, and general use.

Reverse osmosis is a much finer process. Water is pushed through a semipermeable membrane that removes a wide range of dissolved contaminants, not just the ones carbon catches.

That includes thorough removal of disinfection byproducts and many other dissolved solids. It is the highest-purity option for the water you actually drink and cook with.

So whole-home carbon cleans up all your water to a good level, and RO takes your drinking water the rest of the way.

Why not just RO the whole house?

Because RO produces water slowly and at lower pressure than your tap delivers.

It is perfect for a dedicated drinking tap, but it is not practical to run an entire house on RO.

That is why the standard setup is whole-home filtration plus a point-of-use RO system at the kitchen sink. You get good water everywhere and the cleanest water where it matters most.

What about remineralization?

You do not want to drink pure RO water long term, because it strips out minerals.

A good RO setup includes an alkaline and mineral filter that adds healthy minerals back in for taste and balance.

Ours does, and that filter is replaced about once a year for around $199.

What about the fridge or dishwasher?

Fridge line: RO can be plumbed to a fridge, but it adds labor and most people find it is not worth the cost. We will do it if you want it and tell you honestly when it is not worth it.
Dishwasher: Connecting RO to a dishwasher is not recommended. RO produces water slowly, so a dishwasher could outrun the supply mid cycle. The whole-home softener and filter already handle your dishwasher water.

The bottom line

If you already have whole-home filtration and you care about the best possible drinking and cooking water, adding reverse osmosis at the kitchen sink is usually worth it.

If you only have a softener and no filtration, RO matters even more, because the softener does nothing for contaminants or taste.

Frequently Asked Questions

Is reverse osmosis better than a whole-home carbon filter?

For drinking water, yes. RO removes a wider range of dissolved contaminants than carbon. But it is point-of-use, so the ideal setup is whole-home carbon for all water plus RO at the kitchen sink.

Should I remineralize RO water?

Yes. RO removes minerals along with contaminants, so a quality system adds an alkaline and mineral filter to put healthy minerals back for taste and balance.

How much water does RO waste?

Our system runs at about a 2 to 1 ratio, which is efficient for reverse osmosis. The whole-home softener has no water waste.

Can RO connect to my fridge or ice maker?

It can, with extra labor. Many homeowners skip it because the value is low. A dishwasher is not recommended, since RO produces water too slowly to keep up with a cycle.
