Paul is our go-to-guy for air purifier and dehumidifier reviews. His apartment has become a de facto HouseFresh test lab where he pits the latest clean air technology against the perils of city center life. When he’s not putting a purifier through its paces, Paul likes to endlessly dig through dusty record shops (making his dust-free apartment even more important).

Despite there being more information than ever on the prevalence and ill-effects of poor air quality, it still remains criminally overlooked by most homeowners. Instead, our air is rarely given the attention it deserves or thought of as a wider issue that we have no control over. After all, you can’t see, hear, or touch it, so it is easy to neglect. 

It’s important to highlight this oversight, as the air we breathe indoors is actually found to be more harmful than what we would find outside. As a multitude of pollutants, such as dust, mold, or bacteria, become trapped inside the home, thanks to highly efficient insulation and sealed windows and doors. 

This makes for concerning reading, especially when we consider the average American spends 90% of their time indoors, according to the CDC. However, there is something you can do to create a happier and healthier environment for you and your family. Namely, invest in a quality air purifier. This will cleanse the air, removing harmful particles and allowing you to breathe much easier. 

Many of us may also benefit from using a humidifier. Low humidity can cause serious discomfort as it essentially dries out and irritates your eyes, nasal passage, throat, and even lungs. Not to mention, low humidity can also damage your belongings and your home itself, as structures and wooden materials start to dry out and warp.  

A common misconception is that low humidity only affects warm, dry climates. Whilst they will undoubtedly feel the adverse effects, those of you who live in regions with cooler weather are equally affected. Primarily down to the need to heat our homes and spaces to stay comfortable. 

Fortunately, there are some excellent products on the market that can protect you from pollutants and help regulate the moisture levels in homes with low humidity. We’ve selected our favorite air purifier and humidifier combos, to help you revitalize your air and breathe comfortably year-round, even when the humidity drops.

As each of our homes and needs are different, we’ve included five different options for you to choose from. We made sure to cover a range of budgets and brands, whilst paying close attention to each unit’s features and room size suitability, so there is an excellent option for everyone. 

Be sure to check out the full list below.   

1. Dyson PH04 Humidify+Cool 

Dyson is a big name in household cleaning products. They revolutionized the vacuum cleaner and have recently stepped into the air purification and humidifier game. The PH04 rolls both technologies into one, offering a high spec machine that will capture 99.97% of airborne particles, thanks to its H13 HEPA filter, along with a one-gallon water tank, that can add plenty of moisture to your space over the course of 36 hours.   

Along with its top-class H13 HEPA and activated carbon filters to tackle VOCs, Dyson have also included a lifetime catalytic filter, to trap and break down formaldehyde, keeping you protected from the harmful chemical that is released from furnishings and fabrics commonly found in the home. 

Although Dyson doesn’t believe CADR scores offer an accurate account of performance, they do state that this unit can clean 45.6 liters of air a second, which provides us with useful insight into the powerful fans this unit has under the hood.

The purifier has three stages of traditional protection, including a washable pre-filter, an activated carbon filter to tackle household odors, plus a True HEPA filter to eradicate any airborne particulate matter. Sharp have also utilized their Plasmacutter technology in this unit, allowing users to actively charge particles making them earlier for the HEPA filter to remove, providing overall greater efficiency.

Sharp have created a fuss-free control panel, with clearly labeled features. The purifier has three fan speeds, plus an auto mode which enables the machine to monitor air quality levels and adjust the settings accordingly to combat pollutants. You also have the option to turn on or off the Plasmacutter ionizer, select between purifier and humidifier (or operate both simultaneously) as well as dim the LED lights, making it ideal for nighttime use.

Common Questions About Air Purifier and Humidifier Combos

🤔What do Air Purifiers do?

Air purifiers use a powered fan to pull the air in from your room. As the air passes through the unit, pollutants are removed through a series of filters, leaving clean air to be redistributed. The most effective air purifiers will contain a True HEPA filter which can trap pollutants as small as 0.3 microns.

🤔What do Humidifiers do?

A humidifier’s job is to add moisture to dry air in the home. Low humidity can be damaging to your health, causing dry skin, throat, and lips, and can also cause shrinking and even cracking to wooden furniture, so it’s important to regulate moisture levels, aiming for between 30-50% humidity. 

🤔What is a True HEPA Filter?

HEPA stands for High-Efficiency Particulate Arresting. A True HEPA filter is made up of tightly woven glass fibers, which has a 99.97% efficiency rate at capturing small airborne particles. They have become industry standard in air purification, even NASA has studied this type of filter and concluded them to be the best way to clean the air in the home.

🤔Can You Use a Humidifier and Air Purifier at the Same Time?

There’s nothing to stop you from using both devices at the same time. It’s recommended that you use both in the same room as they’re both doing different jobs. As you’re here, you’re most likely looking to get both jobs done with the same device which will save you both money and floor space.

🤔Do Humidifiers Clean The Air?

No. Humidifiers change the amount of moisture in the air. They typically don’t contain the filters needed to clean the air (True HEPA filter) as found in an air purifier.

How We Picked Our Top Choices

We don’t recommend units without being 100% confident in them. We’ve been doing our homework and testing units for X years now and we know what works and what doesn’t. 

The most important features we considered when making this selection were: 

  1. High End – The reality is that having a humidifier and air purifier needs a device that can deal with both issues. Which is why our Dyson, whilst expensive, is our top pick for 2022. 
  2. True air cleaning – Many “humidifiers” say they clean the air but actually do very little. That is why we didn’t include any water air purifiers, as in our performance tests they failed miserably at cleaning the air, although they did help to humidify.
  3. Budget – Our top recommended units are $400 and $800 as these are the best units currently on the market. If you have less budget you might be better off purchasing two units, a cheap air purifier and a cheap humidifier as you could achieve similar results for less than a $200.

SOURCES

Monthly energy consumption costs have been calculated using our air purifier electricity usage calculator, which allows us to calculate daily and yearly costs associated with running an air purifier for 24hs a day. 

You can customize the result by air purifier wattage and by state. In the case of the calculations, we shared on this page, we used California as our base state for energy prices.
