What Are Dehumidifier Air Purifier Combos?

Let’s start with the dehumidifying element.

A dehumidifier is a household appliance that helps you to maintain an appropriate level of humidity in your home.

Zero humidity is bad for you and your home – particularly with regard to items like wooden furniture.

Excess humidity is also bad – in fact, too much humidity can promote the growth of mold, bacteria and other dangerous microorganisms.

A dehumidifier can help you maintain the ideal level of between 30% and 50%.

Air purifiers have the simple, yet vitally important job of removing impurities, contaminants and other dangerous and irritating particles from the air in your home.

There are many types of air purifying technology, but when it comes to air purifier dehumidifier combos, you’re unlikely to find anything other than physical filtration media for air cleaning.

So, if you hadn’t already guessed, in most cases, dehumidifiers and air purifiers are completely separate appliances.

In the case of dehumidifier air purifier combos, you’re getting a 2 in 1 device that dehumidifies and purifies.

This is great for anybody looking to save space in their home, or for those needing both devices, but don’t want to invest in multiple appliances.

These can also be especially effective for people with allergies, as dehumidifiers and air purifiers can each be helpful in that area. With these devices, you’re getting the best of both worlds.

How do Dehumidifier Air Purifier Combos Work?

To get a full understanding of how these devices work, lets it one feature at a time

Air Purifiers

While there are a few different types of air purifiers on the market, when shopping for an air purifier / dehumidifier combo, you’re most likely to come across particle filters for the air purifying function.

The basics of particle filters are easy to imagine: air is forced through a very fine filter and dangerous particles are trapped.

The clean air is then recirculated into the home and you’re breathing easy!

Dehumidifiers

Dehumidifiers work in one of two ways, either by refrigeration or absorption.

Refrigeration

Warm air is sucked into the machine and is rapidly cooled.

As the air gets cold, it can no longer retain water, so the moisture in the air condensates and turns into liquid, falling into a collection tray.

The air is then sent back into the room, free of humidity!

Absorption

These processes work by essentially sucking the moisture right out of the air.

Air is drawn into the dehumidifier via a duct, and is passed by a large wheel made of a material that absorbs water.

This step is what removes the humidity.

The wheel is dried by an electric heating element, and the hot, wet air is blown out via a duct.

When you combine the two functionalities, the particle filtration happens either immediately before or after the dehumidification process, so the air is free of humidity and airborne pollutants.

What Do You Look For In The Best Dehumidifier Air Purifier Combos?

The devices don’t vary too much in the technology used, but there are still some features that set apart the good ones from the not so good! Keep an eye out for these features if you want to find the best dehumidifier air purifier combo devices.

HEPA Filtration

HEPA Filters are considered to be the gold standard when it comes to air filtration. This type of filter relies on the following principles of particle filtration mentioned above.

There are several grades of HEPA filtration that you’ll find in dehumidifier air purifier combos.

Standard True HEPA is identified as either H11 or H12. If you come across a device offering H13, this is considered medical grade, and while it doesn’t technically make it a medical device, it does still offer a much higher standard of filtration.

The best air purifiers are able to remove over 99.97% of particles down to 0.3 microns!

Quiet Operation

Because there are two separate operations going on within the unit, you might find that a combo device is louder than a standalone dehumidifier or air purifier.

With this in mind, finding a nice, quiet model is a good idea.

Sturdy Construction

Again, there’s a lot going on within this device, so you’re going to want to make sure the fit and finish are good, especially as you’ll be taking it apart quite frequently to empty out the water tank.

A poor quality device is likely to leak, too – definitely something you want to avoid.

Large Reservoir

Remember, the dehumidifier has to be emptied regularly.

The larger the tank, the less often you’ll need to remember to do this important job.

The best devices have an automatic shut off when the reservoir is full, and while this is important for safety, if you don’t remember to empty it, you aren’t getting the benefit of the dehumidifier.

Operating Costs and Maintenance

First, consider the approximate filter lifespan, cost, and ease of sourcing.

Can you commit to changing the filter per the recommendations?

Are you happy with the cost of replacement filters?

Are replacement filters easy to find?

If All 3 answers are yes, then that unit should be high on your list.

In addition, a dehumidifier air purifier combo with minimal energy draw will help you to keep electricity costs down, too. This Is especially important if you plan to run the device for extended periods.
