Home Master adds calcium and magnesium back twice, so the water doesn’t taste flat, and its permeate pump cuts waste to about 1:1. Filters last a year and cost about $50 a set.
The catch: No certifier lists the system, so every reduction claim is Home Master’s own. That’s why it scores low on our scale.

Our verdict
The TMAFC-ERP Artesian Full Contact is a seven-stage under-sink reverse osmosis system built around two ideas. First, it passes purified water over a calcium and magnesium blend twice, before and after the tank, which Home Master says gives better-tasting, mineral-rich water. Second, it uses a non-electric permeate pump, which Home Master says raises production by up to 50% and brings waste down to about one gallon per gallon of filtered water.
It’s also easy to maintain. The filters are modules that twist out without tools, Home Master rates them for a year or 2,000 gallons, and the yearly set costs about $50 on Amazon ($79.95 from Home Master). Home Master gives the system a 5-year warranty, longer than most RO brands.
The problem is certification. We found no listing for the system at NSF International, IAPMO R&T or WQA. Home Master says its components meet NSF standards, which covers materials safety, not contaminant reduction, and it publishes no named-lab results. Reverse osmosis generally reduces lead, fluoride and dissolved solids, but our scale only credits claims a certifier or named lab has checked, so this system gets our minimum score for contaminant reduction.
You want reverse osmosis that tastes good, wastes less water and is cheap to maintain, and certification isn’t a deciding factor for you.
You want certified lead or fluoride reduction. The APEC RO-90 and iSpring RCC7AK-BN are certified for both and cost less.
How it scored
Contaminant reduction carries the most weight in the overall score. How we score filters
What it removes
None of these claims is certified. They’re what Home Master says, and what reverse osmosis typically does.
| Contaminant | TMAFC-ERP | Basis |
|---|---|---|
| Total dissolved solids (TDS) | Reduced | Maker claim |
| Lead, fluoride, arsenic | Reduced | Maker claim |
| Chlorine, chloramine | Catalytic carbon stage | Maker claim |
| Calcium, magnesium | Added back, two passes | Design feature |
| PFAS | – | No claim found |
We searched NSF International, WQA and IAPMO R&T under the brand (“Home Master”) and the maker’s legal name (Perfect Water Technologies) on 7 October 2026, and NSF International by model (“TMAFC”) too. NSF International lists the maker only for filter cartridge materials (NSF/ANSI 42) and storage tank materials (NSF/ANSI 58), with no reduction claims. Amazon’s listing says its components “meet or exceed NSF standards”; that refers to materials, not a system-level reduction certification.
What it costs to run
Home Master rates the filters for a year or 2,000 gallons. The ISetTMA8 change set costs about $50 on Amazon (check price) or $79.95 from Home Master, which works out to roughly $0.03 to $0.04 a gallon at the rated capacity. The membrane is replaced separately when its output drops.
Pros and cons
Strengths
- Minerals added back twice for taste
- Permeate pump: about 1:1 waste (maker)
- Yearly filter set for about $50
- 5-year warranty (Home Master)
What to know
- No system certification from NSF International, IAPMO R&T or WQA
- No published named-lab results
- About $400, more than certified rivals
- Under-sink install with drain and faucet hole
What owners say
Owners consistently praise the taste and the low water waste. The usual complaints are the install and cabinet space.
Often praised
- Water that doesn’t taste flat
- Less water down the drain
- Easy yearly filter changes
Common complaints
- Install takes time; fittings can be fiddly
- Tank and modules take cabinet space
- Early fittings sometimes need re-tightening

Common questions
Is the Home Master TMAFC-ERP NSF certified?
Not as a system. We found no listing at NSF International, IAPMO R&T or WQA. Home Master says its components meet NSF standards, which covers materials, not contaminant reduction.
Does it remove fluoride?
Reverse osmosis generally reduces fluoride, but this system isn’t certified for it. For certified fluoride reduction, see the iSpring RCC7AK-BN or APEC RO-90, or read our fluoride guide.
What does the permeate pump do?
It uses the drain water’s pressure to push the system more efficiently. Home Master says it cuts waste to about 1:1 and raises production by up to 50%, with no electricity.
What’s the difference between the TMAFC-ERP and TMAFC-ERP-L?
The -L (“Loaded”) version adds a designer faucet and a refrigerator kit. The filtration is the same.
How often do the filters need changing?
Once a year or every 2,000 gallons, per Home Master, using the ISetTMA8 set.
The bottom line
The Home Master TMAFC-ERP makes pleasant, mineral-rich RO water with little waste and cheap yearly filters. But no certifier lists it, so we can’t credit its reduction claims. If certified lead and fluoride reduction matters to you, the iSpring RCC7AK-BN also adds minerals back and costs less. Compare them all in our reverse osmosis guide.
- Certifier listings: None found for the TMAFC-ERP system. NSF International lists the maker, Perfect Water Technologies, Inc. (Phoenix, AZ), for components only: 28 filter cartridge models under NSF/ANSI 42 (materials only) and 11 storage tank models under NSF/ANSI 58 (materials and structural integrity only).
- Also searched: NSF International ("Home Master", "TMAFC", "Pure Earth"): no listings. WQA ("Home Master", "Pure Earth", "Artesian", "Perfect Water"): no results. IAPMO R&T ("Home Master", "Perfect Water"): no system listing; the only "Home Master" hit was an unrelated pitcher line (W-10420, W-10421).
- Maker documents: Home Master TMAFC-ERP product page and Amazon listing; ISetTMA8 filter set page.
- Independent lab tests: None published.
