I will say that keeping a moderate climate inside your home is sometimes a little hard to do.

That’s why you should know that too much moisture has its problems, just the same way little moisture has its own. In that case, finding the right device to help either situation can be confusing.

That’s why this article answers the question “do air purifiers make the air dry?”

Let’s dive in.

Do Air Purifiers Make the Air Dry?

Air purifiers do not make the air dry. They only remove the pollutants from the air like dust spores, allergens, etc. This means they do not have the mechanism to make the air dry.

Their functions are to clean the air in your room but they can’t add or remove humidity. Air purifiers are used more in the winter period, in place of ventilators.

Do Air Purifiers Make the Air Dry

Moreover, you should understand that cold winter air is dry, meaning you can’t say that air purifiers can cause drier air. For a better understanding of why air purifiers don’t make air dry, we will discuss the following;

Can Air Purifiers Remove Humidity?

The simple answer is no. Air purifiers are not designed to remove moisture content from the air.

Appliances specifically designed to do this are called dehumidifiers. They actively remove moisture in the air with a water tank that fills over time.

But air purifiers don’t have water tanks or any means of extracting moisture from your room. That’s why when any moisture gets into its filters, they are released back into the air.

So if you plan to increase the humidity of your home, then a dehumidifier is the perfect appliance for it.

The Air Feels Dry While Running The Air Purifier?

I know you feel that the air is dry when the air purifier is running. It’s that way because it’s designed to circulate the air in the room, the same way a fan does, making the air feel drier.

Air Feels Dry While Running The Air Purifier

Furthermore, warm air makes us feel that the air is more humid, which is made based on the fact that warm air holds more moisture.

And when there’s cool air, the air purifier circulates air making you feel drier air. Although this might sound true, which is not because air purifiers are designed to circulate air.

They only pulled air into the device causing the airflow speed to be reduced by the filters.

So any time you feel the airflow is contributing to a feeling of dry air, know that your air purifier is on a fan speed, which is too high for your comfort.

Moreover, your room could be too small for the air purifier, which was originally designed for bigger rooms.

So it doesn’t matter how the air in your room feels, one you have to know is that the air purifier didn’t remove the moisture from the air.

Air purifiers are not a necessity unless:

  • You don’t have the option to ventilate your home regularly
  • You have a poor quality of air despite ventilating your home
  • Opening windows and cleaning your home is not sufficient

So if you are the type that is sensitive to indoor air pollutants, suffers from asthma, or has allergic reactions, then an air purifier will become a necessity.

Ventilation is another reason why you need an air purifier for quality air. Before getting an air purifier check if you could improve your home ventilation by;

  • Cleaning your ventilation system, grilles, and vents regularly
  • Leave your internal doors open to increase airflow
  • Regularly open windows to air out your home
