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 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).

The VIVOHOME Water Distiller Countertop is designed to efficiently provide distilled water, making it suitable for use with humidifiers in homes or offices. With a capacity of 1.6 gallons and a 900W power rating, it can distill 1.3 liters of water per hour, which is fairly rapid. Made from food-grade 304 stainless steel and BPA-free plastic, the material quality ensures durability and safety. The inclusion of an extra smart switch and overheat protection adds to the convenience and safety of the device.

The requirement to frequently replace the charcoal filter may be seen as a drawback, especially since the filters are not included. The machine is relatively portable with dimensions of 18 x 10.6 x 8.7 inches and a weight of 11.2 pounds, making it easy to move and store. Maintenance involves regular cleaning after every two uses and replacing charcoal filters weekly, which may be cumbersome for some users. The device is certified for safety, making it suitable for a wide range of applications, including laboratories and dental clinics, aside from home and office use.

The VIVOHOME distiller offers a balance of efficiency, safety, and portability, though the frequent maintenance requirements and absence of included charcoal filters may be points to consider.
