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.

This Dhyala air purifier with humidifier function is designed to handle large spaces up to about 1,730 square feet, making it suitable for big living rooms, open offices, or large bedrooms. Its filtration system is robust, offering an industrial-level air cleaning rate (CADR 265 CFM) that effectively removes dust, smoke, odors, and pet dander. The built-in air quality monitor provides real-time updates on indoor air conditions and allows the purifier to adjust automatically. The humidifier adds moisture with a gentle mist, improving comfort, especially in dry environments, though its 100mL water tank means you'll need to refill it often during extended use. Noise-wise, it performs well in sleep mode, producing just 22 decibels, which is very quiet and unlikely to disturb you at night.

Maintenance involves replacing the filter approximately every three months, with the purifier conveniently alerting you when this is needed. Additional perks include smart app and voice control for easy operation, a child lock for safety, and an automatic two-hour shutoff for the humidifier to conserve energy. One minor downside is that the power plug is fixed to the unit and cannot be detached, which may affect portability. This model is a solid choice for those seeking combined air purification and humidification in larger spaces, with smart features and quiet operation being key benefits.

The AUPU Air Purifier and Humidifier Combo is designed to handle air quality issues in large spaces up to 1546 sq.ft. It offers a three-mode selection, including a quiet sleep mode and a responsive auto mode that adjusts based on air quality. The air purifier utilizes a combination of pre-filter, activated carbon, and HEPA 13 filter to capture 99.97% of airborne particles, making it effective against dust, pollen, smoke, and pet odors.

The humidifier uses evaporative technology with a high water tank capacity of 5.5L and a top-fill design for ease of use. The mist-free humidification prevents added moisture risks common with ultrasonic humidifiers. Although not suitable for use with essential oils, this machine's smart WiFi function allows users to control settings, monitor air quality, and receive maintenance reminders via an app.

The noise level is impressively low at 19.5 dB in sleep mode, ensuring minimal disruption. However, the unit's significant height of 28.35 inches and the need for regular maintenance, such as filter replacements and water tank refilling, might be minor inconveniences for some users. This product is best suited for those looking for a combined air purification and humidification solution for large living spaces, particularly pet owners and individuals with allergies or respiratory sensitivities.
