Plug-in countertop reverse osmosis filter with a glass carafe, best for light use

The verdict
The Carafe is a $375 plug-in reverse osmosis purifier that fills a removable 64 oz glass carafe. It suits one or two people who want RO water without plumbing. The catch is half-gallon batches and filters rated for only 300 to 600 gallons, so heavy use costs more.
The trade-off
You refill it by hand in half-gallon batches, and the filters wear out fast if you use a lot of water.

About this price
List price for the Carafe with the VOC Carbon Filter, without a filter subscription, on AquaTru's product page on Oct 13, 2026, before tax and shipping. The page shows no sale or strikethrough price, and AquaTru's store listing shows no regular price either, so it isn't a markdown. The same page sells the Carafe with the Alkaline Mineral Boost VOC filter for $395 and the Carafe Smart for $425 or $445. A "Carafe + Filter Subscription" option says you save, but the page doesn't say by how much.
A GOOD FIT FOR
One or two people, renters included, who drink under about 0.8 gallons a day and want RO water in a glass carafe.
- You rent or can't drill, and want RO water from an outlet and a 7.5-inch-wide spot on the counter
- One person or a couple drinking under about 0.8 gallons a day, so the filters last their full months
- You want purified water in a glass carafe you can put in the fridge or on the table
- City water under 10 grains per gallon of hardness and 1,500 mg/L TDS
- You want a published lab sheet for lead, fluoride, arsenic, nitrate and PFOA/PFOS before you buy
THINK TWICE IF
- A household that also cooks with filtered water, since the filters wear out by volume and each batch is a half gallon
- Hard water above 10 gpg, unless you soften it first or plan to descale
- Well water with iron, manganese or sulfide above 0.1 mg/L, or water of unknown microbiological safety
- You want filtered water from a faucet without refilling a tank by hand
- You want to confirm the certification in IAPMO's directory before you buy, since AquaTru's own pages disagree on it
What still needs checking
- Whether IAPMO's own listings match the data sheet, including NSF/ANSI 372 and the PFAS beyond PFOA and PFOS
- Which flow figure is right: 0.042 gpm on the data sheet or the 0.0317 gpm a third-party database attributes to IAPMO's listing
- How often to descale, since AquaTru gives no interval
- The filter subscription's discount
- Whether the $49.95 three-year warranty covers the Carafe, and the full warranty terms
- What the tanks are made of
- The recovery rating, which the data sheet doesn't give
The practical details.
| Exact variant | Carafe with VOC Carbon Filter |
|---|---|
| Treatment | 4-stage RO, per AquaTru: pre/carbon filter, RO membrane and VOC carbon filter |
| Rated output | 35 gal a day; 0.042 gpm rated flow; a half-gallon batch in 10 to 15 minutes |
| Water use | 63% efficiency rating, so about 37% of the water you pour in is rejected; recovery not given; no drain line |
| Water capacity | 0.66 gal (2.5 L) tap tank; 64 oz (0.5 gal) removable glass carafe |
| Filter life | Pre/Carbon 6 months or 300 gal; VOC carbon 12 months or 300 gal; RO 24 months or 600 gal |
| Feed water limits | 39 to 100°F; under 10 gpg hardness; up to 1,500 mg/L TDS; pH 3 to 11; cold water only |
| Certification | IAPMO R&T to NSF/ANSI 42, 53, 58, 372 and 401, per AquaTru's data sheet; IAPMO listing not opened |
| Power | 120 V, 60 Hz; 36 W in use and about 4 W idle, per AquaTru's help center |
| Dimensions | 13 in H × 14 in D × 7.5 in W and about 9 lb, from the specifications on AquaTru's product page. The tap water tank holds 0.66 gal (2.5 L), and the clean water tank holds 0.5 gal (1.9 L) in a 64 oz glass carafe. |
| Materials | The carafe is removable 64 oz borosilicate glass, and a spare costs $39.95. The box holds the purifier, one Pre/Carbon filter, one reverse osmosis filter, one VOC filter and a 120 V AC wall plug. The data sheet says the system was tested to NSF/ANSI 372 for lead-free materials and found within acceptable levels. AquaTru doesn't say what the tanks are made of or what media each filter holds. |
Before you buy
InstallationNo plumbing or drilling
No plumbing or drilling. Plug it into a 120 V outlet, fill the tap water tank and run it on the counter. AquaTru says to use cold water only and not to use it on water that's microbiologically unsafe or of unknown quality. The data sheet sets a feed water range of 39 to 100°F and pH 3 to 11, with up to 1,500 mg/L TDS and 10 gpg of hardness. Chlorine must be under 2 ppm, and iron, manganese and sulfide under 0.1 mg/L. If a batch takes 30 minutes or more, it stops and AquaTru recommends descaling. A Carafe descaling kit costs $19.95, and a countertop sliding tray is $29.95.
WarrantyOne-year limited warranty on materials and workmanship…
One-year limited warranty on materials and workmanship, counted from the original purchase date. AquaTru repairs or replaces a defective unit, but you pay a shipping and processing fee. Its help center says the warranty excludes filters, accidents, misuse and failure to maintain the unit, and covers only the original purchaser. A three-year warranty costs $49.95, but that help article doesn't name the Carafe. The help center says to register to see the full policy, and the registration page itself shows no terms.
Returns30-day money-back guarantee, counted from the day it's delivered
30-day money-back guarantee, counted from the day it's delivered. You contact AquaTru, which emails a return label, and you send it back in the original packaging with all parts. The refund covers the purchase price, but shipping and handling costs, including the return label, are deducted. Refunds are processed when the unit reaches AquaTru's warehouse and can take up to 10 business days to show.
More about this assessment
The Carafe is AquaTru's plug-in countertop reverse osmosis purifier, and it fills a removable 64 oz glass carafe. It needs only a 120 V outlet and a 7.5 by 14 inch spot on the counter, with no plumbing. It's $375, and filters run about $130 a year at AquaTru's month limits. The carbon filters are rated for only 300 gallons and the RO filter for 600, so heavy use costs more. AquaTru's data sheet names IAPMO R&T as the certifier, but its FAQ still calls the certification pending. The warranty is one year.
Strengths on paper
- No plumbing, drilling or drain line; it needs only an outlet
- Narrow footprint: 7.5 inches wide and about 9 lb
- The removable glass carafe goes straight to the fridge or table
- AquaTru says a half-gallon batch takes 10 to 15 minutes
- Data sheet reports a 98% minimum lead reduction under NSF/ANSI 58 and a 99.9% average PFOA/PFOS reduction
- Filters cost about $130 a year at AquaTru's month limits, and each one is sold separately
- Power draw is published: 36 W in use and about 4 W idle
- 30-day money-back guarantee from the delivery date
Limitations
- Carbon filters are rated for only 300 gallons and the RO filter for 600, so daily use above about 0.8 gallons raises filter costs
- Half-gallon batches mean frequent refills of the tap tank
- Rated at 63% efficiency, so over a third of the water you pour in ends up as reject
- Feed water should be under 10 gpg hardness; harder water means more frequent descaling
- AquaTru's FAQ still says the Carafe's IAPMO certification is pending, while its product page and data sheet say it's certified
- IAPMO's certificate pages couldn't be opened, and NSF's directory lists no AquaTru products
- Arsenic reduction is rated only for water with free chlorine at the inlet, or water shown to hold only pentavalent arsenic
- One-year warranty that excludes filters; three years of coverage costs $49.95 extra
- Returns lose the shipping and handling costs, including the return label

Recorded recurring parts and refills:
- Carafe One-Year Filter Combo Pack: $99.85 every 12 months. Two Pre/Carbon filters and one VOC carbon filter, a year's worth at AquaTru's month limits. It doesn't include the RO filter. The price equals buying the three filters separately.
- Carafe Reverse Osmosis Filter: $59.95 every 24 months. Lasts 2 years or 600 gallons.
- Carafe Pre/Carbon Filter: $29.95 every 6 months. Lasts 6 months or 300 gallons. Buy it singly if you'd rather skip the combo pack.
- Carafe VOC Carbon Filter: $39.95 every 12 months. Lasts 1 year or 300 gallons. The Mineral Boost Alkaline version costs $49.95 with the same life.
- Carafe Two-Year Filter Combo Pack: $259.65 every 24 months. Four Pre/Carbon filters, two VOC carbon filters and one RO filter. The listing says "save $25", but $259.65 is exactly what the seven filters cost one at a time.
- Carafe Descaling Kit: $19.95. For mineral scale, mainly with hard water. The kit page says to descale regularly but gives no interval. AquaTru's help center suggests descaling when a half-gallon batch takes 30 minutes or more.
- Purchase is the $375 list price on AquaTru's product page on Oct 13, 2026, before tax and shipping.
- Annual consumables are the $99.85 one-year combo pack (two Pre/Carbon filters and one VOC filter) plus half of the $59.95 RO filter, which lasts two years. That's $129.83 a year. The $259.65 two-year pack comes to the same.
- Filter life is also capped by volume: 300 gallons for the Pre/Carbon and VOC filters and 600 for the RO filter. Above about 0.8 gallons a day, the VOC and RO filters reach their gallon limit before their month limit.
- At about 1.6 gallons a day (600 gallons a year), you'd need two Pre/Carbon filters, two VOC filters and one RO filter a year. At single-filter prices that's $199.75 a year.
- Installation is $0 because it sits on the counter and plugs into an outlet.
- AquaTru lists 36 W in use and about 4 W idle, but doesn't say how many hours a day it runs, so hours are left blank. Left plugged in all year, the idle draw alone comes to about 35 kWh.
- There's no required subscription, so other yearly costs are $0. The optional filter subscription's discount isn't stated, and the $49.95 three-year warranty isn't counted.
Evidence & sources.
Do water filters work? Our evidence review grades the research as Strong. That grade is about the claim, not about this product.
- Independent testA third-party filter database reports active IAPMO R&T listings for model AT100, also covering AT110 to AT140, under NSF/ANSI 42, 53, 58 and 401 as of Aug 30, 2026. IAPMO's certificate pages wouldn't load for this review, and its directory showed no search or listings when fetched.1718 The database gives IAPMO certificate numbers 18728 (42), 18729 (53), 18730 (58) and 18731 (401). It doesn't mention NSF/ANSI 372. Treat it as a pointer to IAPMO, not a substitute for the listing.
- CertificationNSF's drinking water treatment directory returns "No Matching Products Found" for the trade name AquaTru. The same third-party database found no WQA listing either.1719 AquaTru names IAPMO R&T as its certifier, not NSF or WQA, so the gap is expected. WQA's directory wasn't searched directly.
- Manufacturer claimAquaTru's Carafe data sheet (rev. 09.25.R5, models AT100 to AT140) names IAPMO R&T as the certifier under NSF/ANSI 42, 53, 58, 372 and 401. Under NSF/ANSI 58, it cut lead from a 0.15 mg/L challenge by 98% minimum and 99.2% on average, against a 0.005 mg/L maximum.3 Other NSF/ANSI 58 minimum reductions: pentavalent arsenic 97.2%, fluoride 94.2%, hexavalent chromium 90.1%, nitrate 97.5%, perchlorate 97.2%, radium 226/228 88% and cysts 99.9%. Three rows (nitrite, nitrate plus nitrite and TDS) list a minimum above the average, which can't both be right. These are lab results at the standard's challenge levels, not measurements of your water.
- Manufacturer claimFor PFOA and PFOS, the sheet lists a 1.5 µg/L challenge, a 0.02 µg/L maximum and a 99.9% average reduction over 300 gallons. It also reports PFNA at 98%, PFHxS at 99.7% and PFHpA at 97.6%.3 The sheet says these were tested to the NSF 53 and 58 protocols and gives averages only, no minimums. Under NSF/ANSI 53 it also lists dozens of VOCs, pesticides and trihalomethanes.
- Manufacturer claimUnder NSF/ANSI 401, the sheet lists 15 emerging compounds, including ibuprofen (97.4%), bisphenol A (99.5%) and DEET (93.3%). Microplastics of 0.5 to under 1 µm fell 98.96%. Under NSF/ANSI 42, chlorine fell 96.8% and chloramine 97.01%.3 Average reductions at the standard's challenge levels, in ng/L for the 401 compounds.
- Manufacturer claimAquaTru's FAQ says the Carafe has passed IAPMO testing for 78 contaminants, with 5 still in testing, and that its certification is pending. The product page says it's certified for 84 contaminants, and the data sheet names IAPMO R&T as the certifier.134 The FAQ looks out of date, but it's still published on AquaTru's site.
- Manufacturer claimAquaTru rates the Carafe at 35 gallons a day, a 0.042 gpm flow and 63% efficiency. Its help center says a half-gallon batch takes 10 to 15 minutes, and it lists 36 W in use and about 4 W at idle.3911 Manufacturer ratings, not independent measurements.
