Tested and certified by the WQA

Certified to the standards that matter, by name.

Anyone can print "99%" on a box. These are the standards the GoodFor 7000 was sent to the WQA and tested against, under set pressure. Ask any other company for the same list.

WQA Gold Seal certified
NSF/ANSI58

Heavy metals, nitrates and cysts

Certified reduction of lead, arsenic (V), cadmium, hexavalent and trivalent chromium, selenium, nitrate and nitrite, cysts like Giardia and Cryptosporidium, and dissolved solids.

NSF/ANSI42

Chlorine taste and odor

Certified reduction of chlorine taste and odor and Class III particulate, so the water tastes like nothing, which is the point.

NSF/ANSI372

Lead-free materials

Every cartridge and fitting certified lead-free. Four stages in three cartridges: a carbon block with an ultrafiltration layer, the RO membrane, and a carbon post-filter.

Runs on house pressure alone. Lose power in a storm, you still have your drinking water.

A check means the WQA tested the 7000 against that contaminant and certified the reduction, at the test conditions in the performance data sheet. The RO membrane also reduces PFAS and fluoride by design; the certified figures for those in our lineup are on the GoodFor 8500.

Installing it

About an hour, under the kitchen sink

Most plumbers and handymen have it running in about an hour. It goes under the kitchen sink, the faucet sits on the counter, the tank sits beside the unit. Minimum 40 psi of house pressure.

Concierge support, for you or your plumber

Text or call us while it goes in. If your plumber has a question about a fitting or the drain line, our plumbers talk to your plumber. Same number after it is in: a filter change, a TDS reading you are not sure about, anything. (833) 488-3489. Prefer we handle the install? Ask; we do in several metros.

Will it fit under my sink?

The unit is 13" wide, 5" deep and 13" tall and hangs on the cabinet wall; the 2.8-gallon tank (14" tall, 10" across) stands on the cabinet floor beside it. A standard sink base has the room. Shallow cabinets under a farm sink: check the 5" depth and the 14" tank, or send a photo to hello@thegoodforco.com before you order.

Renting?

Pair it with the 2-in-1 Kitchen and RO Faucet (sold separately): it replaces your kitchen faucet, so there is no second hole to drill and it comes with you when you move. See the 2-in-1 faucet

What it costs to keep

One set, about every two years.

For a family of three or four, the full set of three about every two years on average: $339, on Auto-Ship Filters if you would rather not have to remember. More people in the house, every 12 to 18 months depending on usage. The TDS meter in the box tells you when. Nothing else wears out. Tank and valves carry a 10-year warranty, and the warranty stays with you, the original purchaser, not the house.

Put that next to what you buy now. A case of bottled water a week is around $600 a year, or two pitcher cartridges a month at $25 each. The set every two years is a fraction of either.

A year of drinking water

Bottled at a case a week; pitcher at two cartridges a month. GoodFor 7000 figure is the two-year set averaged per year, for a family of three or four.

Bottled water, a case a week$600
Pitcher cartridges, two a month$600
GoodFor 7000, every year after year one$170

Around $14 a month to keep, for certified reverse osmosis.

Your household may drink more or less; the proportions hold either way. Shipping is free in the US.

Who this is for

"I want to start with the drinking water."

That is the sentence we hear most on consultation calls, and it is the right place to start. Fix the water you drink and cook with first. Fine-tune everything else later.

The 7000 is certified reverse osmosis with the fewest moving parts in our lineup: three cartridges, one faucet, one tank.

The upgrade most people ask about

Want spring water from your kitchen sink, without the bottles?

Reverse osmosis takes the minerals out with the contaminants. That is why plain RO water tastes flat, and why people keep buying the glass bottles. The Hydration Stack fixes that at the sink: the GoodFor 8500 purifies (the 7000's bigger sibling, certified to 53 and 401 as well), the Sango Coral puts calcium, magnesium and over 70 ocean-derived trace minerals back, and the UMH Pure structures the water as it pours.

Purified, remineralized and structured, every time you open the tap. No case to carry, no delivery to wait for.

What people say after the first glass.

Questions people ask on the call

Before you decide.

Does it reduce PFAS?

The RO membrane reduces PFAS by design. The 7000 carries NSF/ANSI 42, 58 and 372; the certified PFAS figure in our lineup (99% of PFOA and PFOS, NSF/ANSI 53) is on the GoodFor 8500.

How often do I change the filters?

For a family of three or four, the full set of three about every two years on average. More people, every 12 to 18 months depending on usage. The TDS meter tells you: around 60 to 70 is right; when it drops toward 30, it is time.

Is RO water bad for you?

Reverse osmosis takes the minerals out with the contaminants. Add the Sango Coral if you want calcium, magnesium and over 70 ocean-derived trace minerals back, two years per cartridge.

Why only three cartridges?

Stage one is a carbon block with an ultrafiltration layer in the same cartridge, so you get four stages with three parts to replace. Fewer cartridges, fewer things to forget.

Should I wait for a tankless system?

A tankless unit needs a plug. Lose power in a storm and you lose your drinking water. This one runs on house pressure alone.

Should I do the whole home too?

Start here if drinking water is the worry; most people do. Whole home is a different system (chlorine in the shower, scale on the glasses, hard water in the laundry) and it is matched to your water report on a free call, not sold from a page. Book a free whole-home call

Can I return it?

Certified reverse osmosis. Three cartridges. Start here.
