10 Best Water Distiller 2025 in the United States

The Megahome Countertop Water Distiller is a solid choice for those looking to purify their drinking water at home. Its notable strength is the stainless steel construction, which ensures durability and safety, preventing any plastic contamination in the water. With a distillation speed of one gallon every 5.5 hours, it delivers a steady supply of distilled water, although users should be mindful of the time it takes to produce larger quantities. The inclusion of a glass collection bottle adds to the product's appeal by ensuring that the distilled water remains free from toxins that could leach from plastic containers.

One key feature is its UL certification, which guarantees compliance with safety standards that many homeowners appreciate, especially since some insurance policies may require it. The distiller also comes equipped with optional activated charcoal filters to enhance water purity by removing volatile organic compounds (VOCs).

The distiller does consume 580 watts of power, which could be a consideration for energy-conscious users, and its size (10 x 10 x 14 inches) means it requires a dedicated countertop space. While it is not excessively heavy at 7.04 pounds, its bulkiness may pose a challenge for those seeking a portable solution. If you're looking for a reliable and effective water distiller for home use, the Megahome model offers excellent build quality and safety features, though it may be less suitable for those needing a compact or extremely fast distillation solution.

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 CO-Z 6L Water Distiller is designed for those who need a reliable countertop solution for producing distilled water at home, making it a good fit for families, home cooks, and small businesses like dental clinics. Its impressive capacity of 1.6 gallons means fewer refills, which is a significant plus for busy users. The distillation speed of nearly 0.34 gallons per hour is decent, allowing you to have access to purified water without a long wait.

Construction-wise, the distiller uses food-safe stainless steel and durable plastic, making it easy to clean and maintain. The inclusion of a chamber cleaner is a thoughtful addition, as keeping the internals clean is crucial for optimal performance. The design also features a single-button operation, which enhances user-friendliness, making it accessible even for those who might not be tech-savvy.

While the distillation speed is satisfactory, it may not be fast enough for larger households or those needing significant quantities of distilled water quickly. Additionally, the device is somewhat bulky at 10.63 x 8.66 x 17.13 inches, which might limit portability; it’s best suited for a dedicated countertop space. The energy consumption is standard for a 900W device, but users should still be mindful of usage costs based on their needs.
