10 Best Water Distiller 2025 in the United States

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 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.

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.
