How Do Air Purifiers Work?

An air purifier is a device used in homes, offices, and other workspaces whose primary function is to eliminate harmful contaminants from the air. These airborne particles include toxins, dust, pollen, pet dander, gases, mold spores, and more.

An air purifier usually consists of a fan and filter. The fan pulls air into the device, and harmful contaminants are captured and eliminated as the air passes through the filter. As a result, clean and purified air is pushed back into the surroundings.

Air purification goes through several stages, such as

  • Pre-filtration, where larger particles are trapped
  • activated carbon filtration in which unwanted odors and VOCs are removed
  • and finally, HEPA filtration eliminates small pollutants such as bacteria, viruses, mold, and smoke from the air.

Thus, air purifiers only purify your indoor air. These devices are not designed to capture moisture from the air. Specific devices called dehumidifiers are used to remove moisture from the air. Dehumidifiers are electrical appliances that capture excess humidity from the air, thus creating ideal humidity levels in the indoor environment.

Why Does the Air Feel Dry With an Air Purifier?

You might feel like the air is dry when you run your humidifier. This could be caused by several reasons:

Your Air Purifier Circulates Air Too Fast

Usually, warm air tends to feel more humid as it can hold more moisture. On the other hand, cold air feels drier as it retains less moisture. So, when you run the air purifier, its fan circulates air into the room which makes the air cooler that feels dry.

To solve this problem, you can do the following things:

  • Reduce your air purifier’s fan speed
  • Change the outlet position of your device so that the air doesn’t blow directly on your skin.

The Air Purifier is Too Large

Another reason that makes you feel the air is getting dry is that the air purifier is too big for your room. Therefore, make sure to pick an air purifier that has the appropriate size according to the space where you want to place your appliance.

Air Conditioning and Heating

It is possible to feel dry air if you use an air conditioner in your room because air conditioners remove moisture from the room to decrease the temperature. Moreover, furnaces and heaters can also dry out your indoor air.

What Should I Do if My Air is Too Dry?

According to the EPA, indoor humidity levels should be between 30% and 50%. If the air in your home feels dry, you can use a digital hygrometer to check the relative humidity. If the moisture level is too low, it can lead to various health problems, such as dry skin, chapped lips, itchy eyes, and congestion.

You can follow these ways to help get rid of dry air and low humidity levels in your home:

Use a Humidifier

Using a humidifier is an excellent option to balance humidity when the air in your home feels too dry. This appliance releases moisture into the atmosphere through water vapors or mist. Use your humidifier only when needed as excessive moisture may lead to mold formation.

Reduce the Fan Speed

If your air purifier is set at a higher speed, it will circulate air in your home faster, making the air feel drier. Therefore, adjust the device’s fan speed to a lower setting to eliminate this issue.

Keep Yourself Hydrated

Consume more water if you feel the effects of dry air, such as dryness of the nasal passages. You can also apply moisturizers if your skin becomes too dry.

Keep Indoor Houseplants

Keeping houseplants is an affordable option to refresh your indoor air. These can serve as humidifying plants because they increase humidity in the air through evapotranspiration, thereby relieving dry air symptoms.

Seal Your Home

It is possible that during the winter months, cold air gets into your home through the cracks of doors or windows, making the air feel dry. Therefore, check for any gaps to avoid cold air from the outside leaking into your room.

Allergy symptoms such as stuffy nose, itchy eyes, sneezing or coughing

– Bad odors in your home
– The air feels stuffy and stale
– Asthma flare-ups
– Dust on your furniture
– If you snore loudly

Do air purifiers help with humidity?

The primary function of an air purifier is to remove harmful airborne particles. The fan draws air into the device where unwanted air particles are captured. As a result, purified air is expelled into the environment.

Thus an air purifier doesn’t remove or add moisture to the air. It has no effect on the air humidity levels.

Can an air purifier give you a dry throat?

No, air purifiers do not cause dry throat as these devices do not add or remove moisture from the air. A dry throat is usually caused by dry air.

Can you use an air purifier and a humidifier at the same time?

Yes, you can use both these devices at the same time in the same room. Both work differently and neither will have an effect on the other. An air purifier will remove unwanted particles and a humidifier will add moisture to the air providing a clean and comfortable atmosphere.

Final Thoughts

An air purifier has nothing to do with the humidity levels of the atmosphere. It doesn’t add or remove moisture from the air. However, if your air purifier is set at a high setting or is too large for your room, it can make the air feel dry. Using an air conditioner or a heater also makes the air drier.

Fortunately, you can resolve the dry air issue by following the above-mentioned methods. Moreover, using a humidifier will be the best option to relieve symptoms caused by dry air.
