The air in our homes is full of particulate matter or pollutants that can aggravate allergies, asthma, and other respiratory conditions.
Recent research even showed that exposure to air pollutants commonly found in the home can decrease your life expectancy!
Luckily there are devices that can reduce and prevent these types of pollutants in our homes, but which should you use?
Read on for the 3 questions that will help you determine the winner of an air purifier vs dehumidifier.
Air Purifier Vs Dehumidifier: What Do They Actually Do?
Here’s some basic information about the differences between air purifiers and dehumidifiers.
Air purifiers suction air through a series of filters that trap allergy-inducing particles and then recirculate clean air back into the room.
They usually feature a few different types of filters to make sure that even the smallest microparticles can’t recirculate.
A dehumidifier filters moisture particles out of the air. In climates with high humidity or bathrooms or kitchens without fans, moist air can facilitate the growth of mold and mildew. Not only are these growths allergy-inducing, they’re poisonous!
Dehumidifiers simply remove the excess moisture from the air that would allow those things to grow.
What Are You Allergic To?
The next question is obvious! Now that you know what allergens these devices combat, it’s easier to choose an air purifier vs dehumidifier for your specific allergy needs!
If your allergies include pet hair, dust, pollen, or smoke (or other odors) then an air purifier is the way to go! Some are even allergic to the micro dust in cat litter (see this post for some recommendations if this is you).
If mold, mildew, or other moisture-related allergens are the source of your sneezing then the dehumidifier is the clear choice.
But remember, while an air purifier can trap mold and mildew particles it doesn’t prevent them from forming. So if you live in a region with an average of 50% humidity or higher you may want to consider a dehumidifier which prevents additional moisture-related allergens.
If your symptoms are caused by a combination of air pollutants and moisture-related pollutants, the solution might be to try using both devices.
Which one do I need?
We did the work for you! We’ve searched Amazon for the highest rated, most purchased air purifiers and dehumidifiers and this is what we found.
Both of the following models are available on Amazon with prime shipping. They both have great ratings and a high number of reviews. This is important because it shows a lot of people have purchased these items and also had positive experiences.
Both products are appropriately sized for use in a home. Most home models are for single room use, so some customers bought multiple units for different rooms in their home.
And because of their compact design, they’re much quieter than their industrial counterparts.

When it comes to dehumidifiers to help with allergies we recommend Frigidaire dehumidifiers. Since they have many different models and sizes, start by looking at the 70 pint models. There are two reasons for this – 70 pint models have a high capacity water reservoir and they can treat a large space.
High capacity reservoirs need to be emptied less often. Once the reservoir is full, the dehumidifier stops working and you have lost control over the humidity in your home.
70 pint dehumidifiers can work on spaces up to 4,000 square feet. With a capacity this high, in most cases, you will be able to purchase a single dehumidifier for your entire home.
When it comes to specific models we recommend the Frigidaire 70-Pint Dehumidifier with Effortless Humidity Control. It is certified by ENERGY STAR and UL, so you can trust your dehumidifier to save you money on your energy bill and operate in a safe and consistent manner.
