10 Best Water Distiller For Humidifier 2025 in the United States

The Megahome Countertop Water Distiller is a reliable choice for those needing distilled water for their humidifiers. Its capacity is sufficient, distilling 1 gallon every 5.5 hours, which is decent but not the fastest on the market. The material quality is impressive, with a full 304 stainless steel interior and exterior, ensuring durability and no plastic contact with water. This is crucial for those concerned about water purity and safety, especially as it’s UL approved for safety compliance.

The inclusion of optional activated charcoal filters is a good feature for removing additional contaminants like chlorine, though this may add to ongoing costs if you choose to use them regularly. The distiller comes with a glass collection bottle, which is preferable for maintaining water purity, and a porcelain lined nozzle, which adds to its safety features. It’s fairly easy to use, but its size (10 x 10 x 14 inches) and weight (7.04 pounds) mean it’s not the most portable option if you need to move it around frequently.

Maintenance appears straightforward with a 1-year warranty covering defects and malfunctions, but ensuring it remains clean and functional might require regular attention. This distiller is best suited for users who prioritize safety, material quality, and water purity, and are okay with a moderate distillation speed and the need for maintenance.

The CO-Z 6L Water Distiller is a solid choice for anyone looking to purify water in their home, particularly for use in humidifiers, cooking, or drinking. With a capacity of 1.6 gallons and a distillation speed of about 0.34 gallons per hour, it stands out for its ability to produce a decent amount of distilled water without needing constant refills. This feature makes it user-friendly, especially for families or individuals who require water for multiple uses.

One of the notable strengths of this distiller is its quality construction. Made with food-safe stainless steel and plastic, it ensures that the water remains safe for consumption. Additionally, the powerful ventilation fan aids in cooling down the unit, enhancing its performance during operation. The product also includes a chamber cleaner, which simplifies maintenance, a crucial factor for keeping the distillation process efficient and hygienic.

However, there are some drawbacks to consider. The distillation speed, while reasonable, may not be sufficient for larger households or those who need high volumes of distilled water quickly. Additionally, at 12.5 pounds, it might not be the most portable option for those looking to move it around frequently. The noise level during operation could also be a concern for users who prefer quieter appliances.

In terms of size, its dimensions make it a countertop appliance, which is convenient for home use but might take up a significant amount of space in smaller kitchens. The CO-Z 6L Water Distiller is a practical choice for individuals who prioritize ease of use and maintenance in their water distillation needs, though those needing rapid water output or a more compact unit may want to explore other options.

The CO-Z 4L Brushed Stainless Steel Countertop Distiller is designed to provide clean water for various applications, making it a solid choice for home use, especially for those utilizing humidifiers, coffee machines, or CPAP machines. One of its strengths is its capacity to distill water at a rate of 0.3 gallons per hour, which is quite efficient for household needs. The high-quality 304 stainless steel construction ensures durability, while the automatic shut-off feature enhances safety by preventing overheating, making it user-friendly even for those not well-versed in appliance operation.

In terms of maintenance, it includes cleaning powder to help with sediment removal, which is a nice touch for keeping the unit in good condition. The presence of an aluminum fan and stainless steel condenser tubes aids in effective heat dissipation, contributing to faster distillation times.

There are some drawbacks to consider. The distillation speed may not be sufficient for larger families or extensive commercial use, as the water supply could be limited. Additionally, the machine has a relatively bulky size, which might not be ideal for those with limited countertop space. Although it operates quietly compared to other models, there may still be a slight noise during the process that some users could find distracting. Lastly, it's essential to ensure compatibility with your electrical system since it operates at a specific voltage range (110-120V).
