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 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.

The H2o Labs Best-in-Class Countertop Water Distiller (Model 300SS) is designed for those in need of pure distilled water, particularly for use in humidifiers. One of its notable strengths is its stainless steel construction, including the exterior, evaporator, and condensing coil, ensuring durability and a high-quality build. The 1-gallon glass carafe with an ergonomic handle adds to its user-friendliness. With a maximum flow rate of 4 liters per day, it effectively meets the needs for small to medium-scale water distillation.

The 565-watt heating element is optimized to produce gentle steam, enhancing the efficiency of VOC removal without causing splashes. Additionally, the porcelain nozzle insert ensures that distilled water doesn’t come into contact with plastic, maintaining water purity. Safety features like the auto shut-off and fail-safe fuse add layers of protection, making it a reliable option. Maintenance is relatively easy with the wide opening of the evaporation chamber and the included cleaning supplies, which are particularly useful for users with hard water.

Despite its effectiveness, the 300SS model is somewhat bulky at 8”L x 8”W x 15”H and weighs 13.15 pounds, which might be a consideration for those with limited countertop space. Noise level isn't specifically highlighted, but most water distillers tend to produce minimal noise. Users also appreciate the ease of use, with a simple setup process and convenient countertop installation. One potential downside is its slower distillation speed compared to some high-end models. However, for most household needs, its performance and quality make it a strong contender.
