10 Best Water Distiller 2025 in the United States

The H2o Labs Best-in-Class Countertop Water Distiller (Model 300SS) stands out for its robust construction and user-friendly design. The stainless steel exterior and interior components, including the evaporator and condensing coil, ensure durability and hygiene. This distiller comes with a 1 gallon glass carafe that features an ergonomic 'Easy Grip' handle, making it convenient to handle and pour. The porcelain nozzle insert is a thoughtful addition, ensuring that distilled water never comes into contact with plastic, enhancing the purity of the water produced.

The heating element is optimally sized at 565 watts, providing a gentle steam that efficiently removes volatile organic compounds (VOCs) without splashing, leading to effective distillation. The unit's safety features, such as auto shut-off and a fail-safe fuse, add peace of mind during operation. With a maximum flow rate of 4 liters per day, it is suitable for daily household use. The distiller is easy to maintain, thanks to the wide opening of the evaporation chamber, which allows for quick and easy cleaning. For those dealing with hard water, the included cleaning crystals help manage scale buildup.

One of the downsides is the energy consumption, as it may be relatively high due to the continuous heating process. Additionally, the size and weight (13.15 pounds) may make it less portable compared to smaller models. However, its countertop-friendly dimensions (8 x 8 x 15 inches) mean it won’t take up excessive space in your kitchen. In summary, this water distiller is a solid choice for health-conscious individuals looking for a reliable way to produce pure distilled water at home, though it may not be the best option for those seeking a lightweight or highly portable solution.

The VIVOHOME Water Distiller is a countertop unit designed to produce up to 1.3 liters of distilled water per hour from a total 6-liter (1.6 gallon) capacity, making it suitable for home or small office use where moderate daily water consumption is expected. It uses 900 watts of power, which is reasonable for its speed and volume. The parts that come into contact with water are made from durable, food-grade stainless steel and BPA-free plastic, ensuring safety and longevity. Its compact size (about 18" x 10.6" x 10.6") and a weight of around 11 pounds make it portable enough to move around while remaining stable on most countertops.

The design includes helpful features like a smart on/off switch with waterproof protection and non-slip feet, which enhance user convenience and safety. It also has dual overheat protection to prevent accidents, providing an additional safety layer. The distiller does not include charcoal filters, although it uses them to improve water taste and remove odors; these need to be purchased separately and replaced regularly as part of maintenance. The first two batches of distilled water are not recommended for drinking, and regular cleaning with citric acid or vinegar is necessary to manage scale buildup, which might be somewhat inconvenient. Heat emission from the bottom requires placing the unit carefully to avoid damage or burns.

This VIVOHOME model is a reliable and fairly quick water distillation solution for home or office use, especially for those who are comfortable with routine upkeep and purchasing charcoal filters separately.

The CO-Z 1.1 Gallon Water Distiller is designed for home or office use, offering a good balance of capacity and performance. It can produce about 0.3 gallons of distilled water per hour, which adds up to roughly 6 gallons a day—enough for most everyday needs. The interior is made of 304 stainless steel, a food-grade material that resists corrosion and helps keep the water tasting fresh. The included glass pot also avoids plastic contact with the water, which is a plus for purity and flavor. It features an automatic shut-off system that activates at specific temperatures, adding a safety layer and preventing overheating.

This distiller is relatively compact and portable for a countertop model, measuring just under 19 inches long, and weighing about 13.5 pounds, so it won't take up too much space or be difficult to move if needed. The machine uses 750W of power, which is typical for distillers but may be something to consider if energy usage is a priority. An efficient cooling system with aluminum fan blades helps the distillation process run smoothly. Cleaning is made easier with a provided solution to remove limescale and sediment, helping maintain water quality over time.

The unit reduces total dissolved solids (TDS) to about 2 ppm, producing very pure water suitable not only for drinking and cooking but also for coffee machines, humidifiers, and medical devices like CPAP machines. While the distillation speed is decent, it may not be the fastest option for those needing larger volumes quickly. This distiller provides a reliable, safe, and convenient way to get clean distilled water for a variety of uses.
