10 Best Air Purifier With Humidifier Functions 2025 in the United States

The Blueair 2-in-1 Purify + Humidify is a robust solution for those looking to improve air quality and humidity in their homes. With a coverage area of 1,726 square feet, it can efficiently purify and humidify large spaces, making it suitable for living rooms, offices, and nurseries alike. The HEPASilent™ filtration system effectively captures airborne particles, while the 360° InvisibleMist™ Technology ensures balanced humidity levels, providing a comfortable environment.

One of the standout features is the premium refill system that allows for easy water top-offs without needing to disassemble the unit, which is a huge time-saver. The powerful water pump is responsive, alerting users when refills are necessary, and the auto-drying mode prevents the growth of musty smells, keeping the air fresh.

However, there are some drawbacks to consider. Weighing in at nearly 25 pounds, it might be cumbersome to move around if needed. While the maintenance is relatively straightforward with a large tank opening, the filter type is a wick, which may require replacements and can be a bit of a hassle for some users. Additionally, while its noise level is generally quiet, those sensitive to sounds might find it noticeable at higher settings.

The Homedics 2-in-1 Cool Mist Humidifier & Air Purifier stands out with its dual functionality of both humidifying and purifying air, making it a versatile option for indoor air care. It is designed to cover medium to large spaces, with an effective coverage area of up to 416 square feet, suitable for family rooms and bedrooms. The product features a digital air quality sensor that provides real-time, color-coded air quality feedback and an auto mode that adjusts the fan speed based on air quality, which simplifies usage for the user. The stylish tower design ensures it fits aesthetically into your home decor as well.

Additionally, the product includes a remote control for convenient operation. The air purifier and humidifier combination utilizes two filtration technologies to remove airborne allergens, odors, and VOCs, enhancing air quality significantly. The unit can purify the air in an 86 sq. ft. room almost five times per hour, ensuring efficient performance.

On the downside, it may require regular maintenance such as filter and wick changes. Each filter needs replacement approximately every 12 months, which could be a hassle for some users. Despite these minor drawbacks, the Homedics 2-in-1 unit is a strong contender in its category, offering both improved air quality and added humidity to relieve dryness and enhance comfort in your living space.

The Airthereal 2 in 1 Air Purifier with Humidifier is designed for large rooms, up to 1325 square feet, making it ideal for spacious living areas. Its 3-stage filtration system effectively captures tiny particles down to 0.03 microns and tackles PM2.5 air pollution, helping to remove 99.97% of airborne irritants. This ensures a cleaner and fresher indoor atmosphere, particularly beneficial for those with allergies or sensitivities.

The evaporative humidification system offers a healthier alternative to ultrasonic models by filtering water before releasing moisture, avoiding white dust and over-humidification. With a 1.5L water tank, it provides continuous humidification, adapting to real-time conditions for optimal comfort. Intelligent air quality management with real-time PM2.5 detection and automatic fan speed adjustments further enhance indoor air quality.

For ease of use, the unit includes a convenient timer and child lock features, making it suitable for families with children and pets. Additionally, the quiet sleep mode, operating at just 22 dB, ensures a peaceful sleep environment without disturbance. Maintenance is essential for hygiene and optimal performance, requiring regular filter replacements and proper upkeep of the humidification system. While the detachable humidifier is a convenient feature, it may require a bit more effort in terms of maintenance compared to standalone units. This product could be an excellent choice for those wanting a combined air purifier and humidifier solution in a large room setting, provided they are prepared for the maintenance requirements.
