To find the best air purifiers and humidifiers, you’ll need to examine a list of criteria to determine what is most important.

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.

This air purifier and humidifier are very effective, humidifying the air by roughly 40 to 60% allowing for a filter-free operation using a 1. 4-gallon water reservoir, which collects airborne pollutants in a process known as cold evaporative humidification. Venta’s own aromatherapy fragrances can even be inserted into gallons of water for quick deodorizing. Our only knock is that the Airwasher needs to be cleaned every 10-14 days. If this is too much, check out our Dyson HP02 vs TP02 comparison article and our Winix vs Dyson air purifier comparison.

In terms of square footage, this air washer to purify the air is good for rooms up to 600 square feet. Sound levels are very respectable (22dB low setting; / 32 high settings).

Award: BEST FOR LAUNDRY ROOMS

Pros
  • Excellent daily capacity (2.2G/daily)
  • Compact size (11 x 11 x 16 inches)
  • Sleek white casing with a glossy black top panel
Cons
  • Water needs to be refilled every day
  • Not good at capturing ultra-fine particles

This whole-house air purifier and humidifier do an excellent job of filtration using 2-in-1 humidification and an air washing system that uses an evaporator mat to filter pollen, dust, and other airborne contaminants. 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. It is rather limited in digital features, with only a single dial with two fan speeds and an LED indicator to know how much water is left. All in all, it’s a strong performer for larger rooms and larger particles, but so-so with ultra-fine particle filtering. If you are looking for a smaller room coverage, visit the best plug-in air purifier to compare and find out which suits you better.

  • Ambient light sensor for deeper rest
  • Great for rooms up to 2500 square feet
Cons
  • Filter needs frequent replacing
  • Heavy (almost 24 pounds)
  • Bulky design may be off-putting to some people

This best air purifier and humidifier with an 8-stage filtration system is one of the most expensive we’ve searched, featuring a cold catalyst filter, carbon filter, ionic generation, and humidifier to round out the specs. An H13 HEPA filter also captures contaminants down to 0.003 microns, medical-grade, and is excellent for use in health settings.

In terms of digital features, this air purifier and humidifier offers ambient light sensors, which dim or brighten depending on the light available in the room where it sits. It also provides useres with a Wi-Fi app to control speeds and settings, and has a child lock, preventing children from disrupting the settings.

Pros
  • Ultra-slim profile great for tabletops
  • 3 heat settings with varying strength
  • Excellent air distribution
Cons
  • Does not include auto sensor
  • So-so 80 CFM CADR rating

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. Check out the best smart air purifier to compare with more current and digital air purifiers.

How We Decided

We explored efficiency, versatility, and digital controls to determine the best air purifiers and humidifiers to buy.

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 and real-time air quality monitoring for an instant gauge plus humidity level tracking. Extra points for comfort options include an auto mode for automatic fan speed adjustment and Sleep Mode, which turns off all nightlights and places them at their lowest setting, which is 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

What is the big question with great humidifiers and air purifiers? It’s this: Do air purifiers help with allergies? The reason that this question comes up is that many people have allergies. Due to this, many people opt for a great air purifier humidifier combo. Usually, a top humidifier and air purifier combo help keep a person’s nasal passages comfortable while keeping allergens and molds at bay.

Below are the key factors to keep in mind as you shop for a high-end air purifier and humidifier combo in 2022.

The Most Important Features to Consider

  1. 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.
    • As you review and compare the best humidifier air purifiers, square footage ratings should always be more than the room in which you wish to place it. Even if you find the best air purifier with humidifier that matches your room, try to avoid buying it because of aesthetics and focus on square footage.
    • 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.
    • In short, as you compare the leading humidifier purifier, and air purifier vs humidifier models, the more efficient the model, the better air you’ll breathe.
  2. Versatility
    Our 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.
  3. 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.

Air Purifiers and Humidifiers FAQs

Do humidifiers help with air quality?

Humidifiers are responsible for adding moisture to the air, helping to relieve congestion and dryness that could cause skin irritation and other issues. Purifiers with filtration systems are more synonymous with air quality, in that they remove airborne pollutants from the air. We prefer having a humidifier and air purifier together.

Is it OK to leave the air purifier on all night?

Yes, the best practice is to leave an air purifier on all night, as it'll result in maximum efficiency. An always-on air purifier can refresh a room several times an hour depending on its CADR and square footage ratings. With airborne pollutants a never-ending affair, you can leave the air purifier on all night without breaking the bank on energy bills. Some air purifiers even have a night mode function.

Does air purifier make air dry?

No, air purifiers do not leave air dry, as they are not capable of removing moisture from the air. Moisture also does not penetrate air purifiers, so both are mutually exclusive.

Can dirty humidifiers make you sick?

Yes, a contaminated mist or stream can definitely cause breathing and lung-related issues. Asthma and allergy sufferers are particularly vulnerable.
