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 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.

The CO-Z 4L Brushed Stainless Steel Countertop Distiller is a practical choice for those looking to create pure distilled water at home. With a capacity of 4 liters and a distillation speed of 0.3 gallons per hour, it effectively meets everyday needs for clean water, perfect for drinking, cooking, and even applications like aquariums or CPAP machines. The stainless steel construction enhances durability, ensuring a long lifespan while the powder coated finish adds an attractive touch to your kitchen or workspace.

One standout feature is its automatic shut-off function, which activates when the water reaches a high temperature, effectively preventing overheating and adding a layer of safety during use. The design also includes efficient heat dissipation mechanisms, such as an aluminum fan and double rows of stainless steel condenser tubes, contributing to a faster distillation process.

There are some considerations to keep in mind. The 750W power requirement means this distiller is not the most energy-efficient option available, especially if you plan to use it frequently. Additionally, the size (12.4” x 11” x 18.8”) may be cumbersome for those with limited countertop space or seeking portability. Although the unit is designed for ease of use, regular maintenance is necessary, including cleaning to remove sediment and scale buildup, which could be a hassle for some users.
