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 Afloia 2 in 1 Air Purifier with Humidifier is a versatile device designed to both clean and humidify the air. It features a 3-stage filtration system, including a prefilter, activated carbon filter, and another filter, which ensures thorough air purification. This device can filter the air in a room up to 438 square feet every 24 minutes, making it suitable for medium-sized spaces. The evaporative humidifier function offers pure humidification without mist, eliminating the risk of dust accumulation and water leakage, which is beneficial for those with allergies or respiratory issues.

A notable feature is the filter replacement alert, which advises when it's time to change the filter, ensuring optimal performance. Additionally, the device includes a night light with three modes, enhancing its usability in a bedroom setting. However, the humidifier module cannot be used independently, which might be a limitation for some users. The noise level is low, promoting a quiet environment ideal for sleeping. Maintenance requires regular filter replacements every 3-6 months, which could be considered a drawback due to ongoing costs.

This air purifier with humidifier is best suited for users looking for a combined solution for air purification and humidification in medium-sized rooms, with added features like night lighting and filter alerts.
