10 Best Costco Water Dispensers 2026 in the United States

The AquaTru Classic is a countertop water purifier that uses a certified 4-stage reverse osmosis system to remove 84 contaminants, including harmful chemicals like lead, fluoride, microplastics, and forever chemicals (PFOA/PFOS). This makes it a strong choice for anyone wanting thoroughly purified drinking water without complicated plumbing. It’s designed to be portable and fits well in apartments or rentals where permanent installation isn’t an option. The unit holds about 2.7 liters (roughly 1 gallon), which suits small families or individuals but may require frequent refills for larger households.

The filtration system is effective and long-lasting, with filters that can last from six months up to two years, reducing plastic waste and ongoing costs. However, the AquaTru does not offer temperature options like hot or cold water, which limits its use if you want instant chilled or heated water from your dispenser. It also runs on corded electricity, so it’s not battery-operated or smart-home compatible, which might be a downside for some.

The design is compact and straightforward, making it easy to maintain with tool-free filter changes, but it has a basic plastic exterior that may not appeal to those looking for a more stylish or modern look. Energy efficiency specifics aren’t highlighted, but reverse osmosis systems typically use some power continuously. The AquaTru Classic is ideal for users focused on highly purified water and ease of setup, especially in smaller living spaces, but less suitable if you want temperature control or a more decorative appliance.

The AquaTru Glass Carafe is a countertop water purifier that uses a 4-stage reverse osmosis system to remove a wide range of contaminants, including microplastics, lead, and harmful chemicals like PFOA and PFOS. It also adds alkaline minerals to improve taste and potentially provide health benefits. Designed for convenience, it requires no plumbing or installation—just plug it in and fill the tank with tap water. The purified water is dispensed into a stylish borosilicate glass carafe, which looks elegant and fits nicely on most kitchen counters.

This model has good capacity for daily use and its filters last from six months up to a year, making maintenance relatively low effort. However, it doesn’t offer temperature options, so you won’t get chilled or hot water directly from it, which might be a drawback if you prefer that feature in a water dispenser. While the purifier is energy efficient with a gentle flow rate, it’s not compatible with smart home systems.

It is well suited for those who prioritize clean, highly filtered water and prefer an easy-to-use, compact countertop option without complicated setup. This purifier is especially useful if you want to avoid buying bottled water and value removing tough contaminants, but if temperature control is important, you might need to look elsewhere.

The AquaTru Classic is a countertop reverse osmosis water purifier designed for those who want highly purified drinking water without the hassle of plumbing or installation. It effectively removes 84 contaminants including lead, fluoride, chlorine, microplastics, and harmful chemicals, which makes it excellent for improving water taste and safety. Its 4-stage filtration system is certified for strong contaminant reduction, and the unit adds healthy minerals back, which some other RO systems lack.

The 1-gallon water tank capacity is good for daily family use, though it provides room temperature water only as it lacks hot or cold water temperature options. This might be a drawback if you expect a traditional water dispenser with hot and cold settings. The unit is portable, compact, and made from BPA-free plastic, so it fits well in apartments or rentals and is easy to move or store.

Filter replacements are straightforward and cost-effective, lasting between 6 months to 2 years depending on use, which helps reduce plastic waste and saves money over bottled water. However, at about 23 pounds and with dimensions around 14x12x14 inches, it’s not the lightest or smallest purifier out there. It doesn’t connect to any smart home systems and does not require electricity for heating or cooling, which keeps energy use low but limits features. If you want a simple, no-fuss purifier that delivers clean, great-tasting water on your countertop without plumbing, this is a solid choice. But if you need hot/cold water options or a dispenser with more modern smart features, you might want to look elsewhere.
