To find the best air purifiers and humidifiers, you’ll need to examine a list of criteria to determine what is most important. We recommend the best air purifiers and humidifiers with a high square footage rating, high CADR (clean air delivery rate) scores, and a minimum 3-stage filtration that uses a pre-filter for larger particles, a true HEPA filter for ultrafine particles, and an activated carbon filter to obliterate smoke, odors, and gasses. On the leading humidifier side, we look for a generous reservoir capacity and smart filter/reservoir change reminders for easy management. Don’t forget digital controls, such as real-time air quality monitoring and smartphone app compatibility to schedule settings from afar.

Venta’s own aromatherapy fragrances can even be inserted into the gallons of water for quick deodorizing. Our only knock is that the Airwasher needs to be cleaned every 10-14 days.

An integrated fragrance container can accommodate essential oils for a quick sprucing and two operation modes focus on fan speed intensity (higher output for Day and whisper-quiet operation for Night)
We love this air purifier and humidifier’s room coverage, good for up to 540 square feet. This could be a premiere air purifier for pets, especially big dogs.

This workhorse does a little bit of everything well. It’s the only unit to offer a heater using three heat settings, combined with 4-stage filtration that includes a true HEPA filter for 0. 3-micron contaminants killing, good enough to replace the air in your room every 20 minutes.
We like the number of humidifier settings (3) and heating settings (3), along with a water tank fill indicator to let users know when it’s time to replace the tank. All in all, this is the only purifier, heater, humidifier, and cooling fan combo on the list, making it a special pick.

How We Decided
In determining the best air purifiers and humidifiers to buy, we explored efficiency, versatility, and digital controls.
In terms of efficiency, we prefer the best air purifiers and humidifiers to have a minimum 3-stage filtration system or higher that uses a filter, a true HEPA filter, and an activated carbon filter. Bonus points for additional layers of defense, such as built-in UV-C lights and ionizers for additional fighting power. On the humidifier side, reservoirs should be large enough not to have to fill regularly.
On the digital side, we are fans of humidifiers with various settings (heating, purifying, moisture) that allows users to better control output based on their comfort levels. Look for a water tank fill indicator to let users know when it’s time to replace the tank, as well as real-time air quality monitoring for an instant gauge plus humidity level tracking. Extra points for comfort options, including an auto mode for automatic fan speed adjustment and Sleep Mode, which turns off all nightlights and places it at its lowest setting, great for nighttime sleep. For this guide, we focused on the performance and features versus if the model would make a good portable air purifier.
Best Air Purifiers and Humidifiers Buying Guide
The Most Important Features to Consider
- Efficiency
Look for the best air purifiers for asthma and great humidifiers with a minimum 3-stage filtration system or higher that uses a filter, a true HEPA filter, and an activated carbon filter. Square footage ratings should always be more than the room you wish to place it in. High CADR ratings are also representative of how fast air changers circulate throughout the room and wipe out smoke, dust particles, and pollen to mitigate allergy symptoms and asthma symptoms. Be aware of the carbon monoxide limits of air purifiers though, since these aren’t equipped to fully clear up a major leak, even if they have advanced features or act as a HEPA air purifier. - Versatility
In our versatility, versatility means all the extras that put the best air purifier and humidifier above the rest. We are big fans of additional layers of defense, such as 345nm wavelength UV lamps and built-in ionizers. - Digital Controls
The more expansive the digital controls, the easiest it is to optimize your air purifier and humidifier. Look for a combination of real-time air quality monitor, Sleep Mode, Auto Mode, and multiple humidifier settings to control the amount of moisture dispersed in the air.
