Can Air Purifiers Make the Air Dry?

When people are buying an air purifier, they always ask a question. “Do air purifiers dry out the air?” I have a short and sweet answer “NO”. Air purifiers are specially made to remove mold, pollutants, dust, pollen, pet hair, pet dander, and air particles.

Well, there are hundreds of air purifiers available in the market. However, most of the air purifiers are unable to reduce moisture from the air. Air purifiers that have humidifier or dehumidifier feature, which can affect the humidity level. But most of the air purifiers do not have this feature. Because they are specially designed to clean the air.

An air conditioner can remove moisture and make air dry. But an air purifier cannot. When indoor air is cold then the humidity level is always low. And cold air cannot hold moisture.

It does not mean that with air purifier your humidity level will be stable. Humidity is naturally based on climate. It can change according to the environment and climate. We will discuss this later. First of all, understand what humidity level is.

What Is Humidity Level?

The humidity is the amount of water vapor in the air. Humidity is important to understand. It affects weather, climate and also indoor environments. Low humidity and high humidity can be dangerous. High humidity with high temperatures can cause major health issues.

You have heard the word “Relative Humidity” in news or weather reports. You can also call the humidity level. The relative humidity is a ratio of water vapor that air has held.

Let’s understand this with an example. A glass can hold 100ml water, but now it has held 50ml water. This means the glass contains 50% of its capacity.

The ideal percentage of humidity is 40 to 50 percent. 40 to 50 percent humidity is good for health. Above 60% is harmful to indoor air and our health. 100% humidity means air is so moist and 0% humidity means air is dry.

You can check humidity by hygrometer or indoor humidity monitor. You should purchase these tools to check the humidity level of your indoor air.

What if Indoor Air Humidity Is Too High or Too Low?

As I said before because your air purifier cannot remove moisture your indoor air humidity is stable. Humidity is natural. We should know that how to control the moisture and humidity in the Home. What if air humidity is high or low?

If humidity is low then indoor air is dry. And dry air can be the reason for skin problems and other health issues.

If humidity is high then indoor air is so moist. Moist air can cause many health issues. And it makes a perfect environment for mold and other microorganisms. It is important to maintain ideal humidity levels.

We have some products to control humidity. If your indoor air humidity is low then you should prefer a humidifier. If your indoor air humidity is high then you should prefer a dehumidifier. These are the best tools to control indoor air humidity.

What Is Humidifier?

The humidifier is a product that adds moisture to the air. We know that low humidity means air is too dry. And dry air can cause skin, nose and lips problems. The humidifier adds moisture to the air and prevents dryness from the air.

There are five types of humidifiers available in the market.

  • Steam vaporizer
  • Ultrasonic humidifiers
  • Evaporators
  • Impeller humidifiers
  • Central humidifiers

But overusing the humidifier can make the air too moist and increase the air humidity. Before buying a humidifier you should know how to use this product. You should know that the humidity level must be between 30% to 50%. High & low humidity can cause major health issues.

What Is a Dehumidifier?

A dehumidifier is an electric machine that can remove moisture from the air and reduce humidity. The dehumidifier works like an air conditioner and refrigerator. Dehumidifiers reduce moisture from the air that passes through the unit. Below are the steps for how a dehumidifier works.

  1. Dehumidifier sucks air from the room
  2. Then the air passes through the cold pipes
  3. As the air cold moisture turns back into liquid water and drips down
  4. After that air passes through a hot compressor and backs up to its original temperature
  5. Now dehumidifier blows back the dry air into the room
  6. Moisture is collected by a large tray
  7. When the tray is full, the fan turns off and indicates that the tray needs to empty

There are two types of dehumidifiers.

  • Condensate dehumidifiers
  • Desiccant dehumidifiers

The dehumidifier is like a mini air conditioner or mini-refrigerator.

Final Verdict
