There’s nothing like breathing in clean, fresh air. Unfortunately, however, indoor air can be up to 5 times more contaminated than outdoor air, and poor air quality can affect your health as well as your brainpower. Buying an air purifier is a great solution as it’ll effectively remove airborne pollutants, like pollen, dust mites, and pet dander

But if you also live in a dry environment or suffer from persistent coughing, then you’ll know how uncomfortable 20%-30% relative humidity feels. A good humidifier will help to raise humidity rates by increasing moisture levels. This can be especially useful during the cold and flu seasons.

But you don’t have to buy a separate air purifier and humidifier to get all the benefits. Whether you don’t have much space or just want something more convenient, there are some excellent purifier/humidifier combo options out there. Luckily, we’re here to help you find the right one for your needs.

The best purifiers contain true HEPA filters. These capture the greatest number of harmful airborne particles, reducing the growth of bacteria and the spread of toxins. And while there are different types of humidifiers on the market, an evaporative unit is most effective when used in conjunction with a purifier.

When picking out our top choices, we also looked at special features like:

  • Low noise levels
  • Easily refillable
  • Touchscreen controls
  • Wireless technology

It’s important to think about the size of your space together with your budget before purchasing your unit. The Envion 4-in-1 Air Purifier is our top budget buy and covers 250 square feet. However, the Sharp Triple Action Plasmacluster Air Purifier might be more suitable if you have extra money to spare as it covers 254 square feet.

To ensure we found the best air purifier/humidifiers, we used consumer reports analysis to remove any false and unhelpful reviews. All our recommendations came from genuine people like you who have used these models, so you can be sure to trust them.

1. Sharp Triple Action Plasmacluster

The Sharp Triple Action Plasmacluster Air Purifier is designed to make the air in your space more comfortable no matter what season you’re in. It does so by using a triple filtration setup. The first line of defense is the pre-filter that captures larger airborne particles. It’s washable as well so that it can last longer. Then this unit has an activated carbon deodorizing filter that helps eliminate odors. Finally, there is the HEPA filter that removes roughly 99.97% of particles that can be as small as 0.3 microns.

Besides the filtration capability, this unit also has plasma cluster ion technology. This focuses on removing more microscopic pollutants the filters may miss by producing both positive and negative ions using the water vapor in the air.

It features a straightforward control panel at the top. From there, you can turn the ion lights on, off, or dim them. You can also adjust the fan speed and set the mode as to whether you want it to just clean the air or clean and humidify the air. There’s even a quick clean mode when you only want the unit to run briefly. This has a smart sensor built-in as well. If you set it in auto mode, the fan will adjust itself depending on the level of particles it detects in the air. It doesn’t just detect airborne pollutants, but it will track odors as well.

Features:

  • Purifier Technology: HEPA
  • Room Size Suitability: 254 sq. ft
  • Filter Life: 2 years
  • Noise Level: 19 to 26 decibels
  • Monthly Energy Consumption: $0.29 to $1.86

  • Creates a minimal amount of noise on lower fan speeds
  • The filters last a good deal of time before needing to be replaced
  • Easy to remove the water tank for refilling

  • Due to its size, you may need to make room to set it up
  • The humidifier tank could benefit from being a little larger to reduce refill frequency

2. Venta LW45 Original Airwasher

The Venta Original Airwasher is a reliable way to get fresher air indoors, and all you need is some tap water this robust machine, which is then released into the air. It works to naturally cut down on indoor airborne pollutants. This is not only one of the most natural ways to clean the air around you, but it is also a hygienic way since it focuses on using evaporative humidification.

Since there are no filters used, all you have to focus on is cleaning the unit in order to maintain it. Both the motor and the housing can be removed for easier maintenance. It’s recommended to clean the unit out every 10-14 days. Once everything is emptied and wiped down, you can refill it with freshwater as well as adding an Water Treatment Additive.

Designed for large spaces, this unit can raise humidity levels to a comfortable 40-60%. This is just enough to help naturally reduce those airborne pollutants without making the space overly moist and potentially causing other issues such as mold. It can handle large spaces as well, and it can even work for open floor plans to tackle multiple rooms at once. There’s just one on/off button as well as up to three power levels to choose from. You don’t have to worry about turning it off as it automatically shuts off if the water is low.

  • Purifier Technology: Cold evaporative humidification
  • Room Size Suitability: 600 sq. ft
  • Filter Clean: Every 10 to 14 days

  • Simple to set the unit up out of the way

For one thing, it acts as a heater, making it worthwhile in the winter to add that extra bit of warmth to a room. Secondly, it is an air purifier, working to eliminate common airborne pollutants. Lastly, it has a built-in humidifier, adding much-needed moisture so that the air doesn’t get too dry even after you’ve used the heating element to warm things up.

With its advanced technology, the unit also reduces common household odors. This includes harsh cooking smells, odors from pets, and even cigarette smoke. It’s an easy way to add comfort to your home at all levels. Plus, this is a more economical approach considering you can turn down the thermostat in exchange for just heating up the room that is actually occupied rather than the entire house or apartment.

This unit is easy to use too. It features an LCD display with seamless operation. There’s even a quiet mode you can turn on as well as an automatic timer so you can set it and forget it. For those with pets or children, the GreenTech is safe to be around. With the PTC technology, this unit can’t overheat. This ensures that the front grille and the casing are not hot to the touch.

The Focus LS-AP350 PURA Max is a unit fitting for larger rooms. With its 4-stage filtration system, the unit goes to work in reducing airborne pollutants like pollen, dust, mold spores, germs, and more. It even helps eliminate odors common in households such as cooking smells. The unit manages all this thanks to the pre-filter, fiber mesh filter, activated carbon filter, and a HEPA filter. The HEPA filter allows the unit to capture and eliminate pollutants as small as 0.3 microns.

Other than purifying the air, the unit will add helpful moisture to the air. It has a built-in cool-mist humidifier function. Even with this running, the air purifier can still work in the background. So, you can capture contaminants from the air while also raising humidity levels to help with issues like coughs and congestion. Keeping an eye on the unit is simple too as there’s an empty water tank indicator and a filter replacement indicator light.

The LS-AP350 cleans the air quickly to allow little ones to breathe easier in a childs bedroom, especially at night or if they’re sick.

This makes the unit great for use during allergy season in the spring as well as flu season in the fall/winter.

Next up is the ceramic heater element. It can help you save more money in the winter months by efficiently warming up whatever room it’s placed in. The third function is the humidifying component. This can be helpful during flu season as well. Lastly, this has a built-in fan, perfect for those hot summer days.

The FS200 is intended for medium to large-sized rooms, and thanks to it being light in weight, you can readily move it around from room to room.

FAQs About Air Purifiers/Humidifiers

What are the functions of a humidifier compared to an air purifier?

A humidifier is designed to add moisture to the air. They are designed so that they can offer warm moisture or cool moisture. When you look at an air purifier, this device is designed to purify the air. It doesn’t release any moisture in the air. Instead, it pulls in air, removing various airborne pollutants depending on the filters inside, and releases cleaner air back out.

Both a humidifier and an air purifier can make the air easier and healthier to breathe, however. Humidifiers work to provide more humidity to the air, which can help render virus particles ineffective, making them useful during cold and flu seasons. Air purifiers remove pollen, dust, and even some airborne bacteria and viruses.

Does a humidifier help purify the air?

No, a humidifier on its own can’t exactly purify the air. It’s built to add moisture to the air to raise humidity levels. That doesn’t mean it can’t help though. A humidifier can still make the air around you more comfortable, especially if you are sick or suffering from allergies. Moisture can help clear out congestion, making it easier to breathe through your nose as well as helping your coughs become more productive. If you want to completely purify the air from airborne particles, however, then it’s best to get an air purifier instead of just using a humidifier.

Do air purifiers work better with a humidifier?

Since both air purifiers and humidifiers can improve indoor air quality, it makes sense that many would want to use the two together. This way, you can reap the benefits of them both with the air purifier eliminating common airborne ailments like allergens and the humidifier adding needed moisture to an otherwise overly dry room.

You can have an air purifier running alongside a humidifier, but you want to take care of the type you choose. Only an evaporative humidifier should run in the same room as an air purifier. This is because the visible mist humidifiers release dense mist that can cause some harm to the filters inside air purifiers. Combination units skip this problem by providing a unit that works seamlessly and incorporates features from both air purifiers and humidifiers.

Which Air Purifier is Best for You?

Finding the right air purifier with humidifying qualities should take some careful consideration. Not all air purifiers are made the same. Some have smart features such as sensors or even app compatibility so you can control the unit when you’re not home. Some have multiple modes and various speed levels, others may be designed with specific seasons in mind such as being better used in warmer weather or colder weather while some units are best for all-season use.

There are many air purifier and humidifier units that boast even more features such as acting as a fan or even a heater. It is important to understand what you’re looking for so that you come away with the air purifier and humidifier combo that is best for your home needs.
