AquaTru Carafe 64oz, Alkaline Mineral Boost review

The Carafe with a mineral-boost finishing filter

SKU 90AT100ATA01 is the AquaTru Carafe package with the Alkaline Mineral Boost VOC Filter. The most important choice is still the appliance format: the machine uses power for a reverse-osmosis filtering cycle, but the clean water collects in a removable 64-ounce glass carafe that you pour yourself. It is not a button dispenser, and it is not a passive gravity pitcher. If the main reason you are shopping is to avoid plugging in and tending a tap-water tank, a conventional pour-through pitcher will be simpler. If you want a small, separate reservoir of filtered water to carry or refrigerate, this powered-pour design is worth comparing.

The page lists a 2.5-liter feed tank, a 1.9-liter clean-water tank, 120-volt power and an appliance footprint of 7.5 by 14 by 13 inches. The 64-ounce carafe holds eight ordinary eight-ounce servings as a unit conversion, but it does not produce eight cups at the instant raw water is poured into the separate feed tank. You wait for the filtration cycle, and the manufacturer does not publish a single guaranteed household cycle time. Allow space to lift out both tanks and empty the used water rather than placing the unit in a tight spot just because the purifier itself looks compact in its product image.

What changes, and what does not

The box and Carafe performance sheet distinguish a standard VOC Carbon finishing filter (10AT100VF01) from this Alkaline Mineral Boost VOC filter (10AT100VFA01). AquaTru describes the boost as adding calcium and magnesium after the RO stage. That is a manufacturer-described mineral and taste feature; it is not evidence of a medical benefit or a reason to infer a different health outcome. If you do not care about the mineralized finish, the standard VOC Carafe package is the more direct route. If you prefer the maker's post-RO mineral feature, this exact SKU documents that option.

The PDS names the AT100–AT140 system family but does not map retail SKU 90AT100ATA01 one-to-one to a system code. Its mineral-boost cartridge is identified, but the contaminant table remains family-level; get an exact SKU-and-cartridge performance record if a named reduction is essential.

The common Carafe sheet lists its AT100–AT140 product family and performance claims for NSF/ANSI 42, 53, 58 and 401, plus NSF/ANSI 372 lead-free construction. It includes both the regular VOC and mineral-boost replacement filter part numbers. Its named tables include lead, fluoride, PFOA/PFOS, cysts, chlorine, chloramine and TDS, among other substances. A claim belongs to the conditions and filter configuration documented in the sheet; it does not mean every possible contaminant is removed. AquaTru's manual is explicit that the appliance is for cold municipal or otherwise known microbiologically safe water. Cyst results in a performance table are not a reason to put unsafe or unknown water through a countertop RO appliance.

Replacement and cleaning are part of the purchase

The three internal cartridges have different service intervals: pre/carbon, 300 gallons or six months; reverse osmosis, 600 gallons or 24 months; and the mineral-boost VOC cartridge, 300 gallons or 12 months. They are separate maximums, not one promise that the whole unit goes a year without attention. Usage and source water can change timing. When the unit asks for a tank refill, dump the concentrated remainder from the feed tank before refilling; failure to do so can damage the system and void the warranty. Wash the carafe and tanks weekly by hand, keep them away from sunlight and hot surfaces, and watch for scaling. The product data sheet sets a maximum hardness of 10 gpg unless water is softened before it enters the unit.

The practical tradeoff is clear: this version spends more counter space and adds electrical and waste-water chores to get RO filtration into a pourable, removable vessel. It does not give you instantaneous water at a faucet, and the added mineral filter does not shorten those chores. Carafe Smart models add the manufacturer's app and Wi-Fi onboarding; they are separate SKUs, not a software toggle on this non-Smart package. Compare those models only if you actually want connected filter-life and usage tracking.

Its Alkaline Mineral Boost seal and award badge are visible in the composite; neither graphic is an independent filtration test.
