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 Dyson Purifier Humidify+Cool PH2 De-NOx is a smart choice if you're looking for an air purifier that also humidifies and cools your space. It covers a decent floor area of 270 square feet, making it suitable for medium-sized rooms like bedrooms or living areas. Its filtration system is strong, using a fully sealed 3-stage HEPA H13 filter that traps 99.97% of tiny particles, including bacteria and pollutants like nitrogen dioxide (NO₂), which it removes 50% more effectively than many other purifiers. It also tackles odors, gases, and continuously breaks down formaldehyde, helping to keep your indoor air cleaner.

The humidification function is hygienic, killing 99.9% of bacteria in the water, which is great for adding moisture without spreading germs. Besides purification and humidifying, it cools the room with a smooth airflow thanks to Dyson’s Air Multiplier technology that moves air efficiently and can oscillate up to 350° to spread it around. You can control and monitor air quality remotely via the MyDyson app or with voice commands, and it even offers personalized air quality reports.

Dyson products are often positioned at a premium price point compared to typical air purifiers with humidifiers. The unit’s tall and slim design requires some vertical space. Dyson machines are generally designed to operate quietly, though some sound may be noticeable on higher settings. Maintenance involves replacing filters and cleaning, which is standard but important to consider for ongoing costs and effort. This Dyson model is a high-tech, reliable device that combines air purification, humidification, and cooling with smart controls, making it well-suited for medium-sized rooms and individuals sensitive to air quality.

The InvisiClean AquaNova is a versatile 2-in-1 air purifier and humidifier designed for spaces up to 1100 square feet, making it suitable for large rooms and small apartments. One of its standout features is its multi-stage filtration system, including a pre-filter and true HEPA filter, which effectively captures 99.97% of airborne particles as small as 0.3 microns. This ensures that the air you breathe is clean and fresh. Additionally, the evaporative humidification filter adds moisture to the air without causing excess humidity, making it self-regulating and easy to manage with plain tap water.

This product is equipped with smart features such as WiFi connectivity for remote control, real-time air quality and humidity display, and alerts for when the water needs to be refilled or filters need changing. It's also energy-efficient, costing less than 20 cents per day to run even on turbo mode. One of its major advantages is its ultra-quiet operation, making it ideal for use in bedrooms or offices without causing disruption.

However, it's essential to consider that the dual functionality may require more frequent maintenance, especially in terms of filter and water changes. The product's dimensions are relatively compact at 10 x 10 x 19.5 inches, and it weighs 8.7 pounds, making it easy to move around if needed. This unit is backed by customer support based in the USA, and it is certified by multiple agencies, ensuring its reliability and safety.
