Emerging Trends and the Growing Use of Air Purifiers in Improving Indoor Air Quality

Indoor air quality has always been a significant concern, but the pandemic has brought it to the forefront of people's minds. As people spend more time indoors, it's essential to ensure that the air they breathe is clean and healthy. In recent years, air purifiers have become increasingly popular as a solution to indoor air pollution. This article will explore the emerging trends and the growing use of air purifiers in improving indoor air quality.

What are air purifiers and how do they work?

Air purifiers are devices that remove pollutants, allergens, and other harmful particles from the air. They work by drawing air into the device, passing it through a filter or multiple filters, and then releasing the clean air back into the room. The filters can capture various pollutants, such as dust, pollen, smoke, and even bacteria and viruses.

There are several types of air purifiers, including HEPA filters, activated carbon filters, and ionizers. HEPA filters are the most common type and can remove up to 99.97% of airborne particles as small as 0.3 microns. Activated carbon filters are effective at removing odors and gases, while ionizers emit negatively charged ions to attract and remove pollutants from the air.

Emerging trends in air purifiers

As the demand for air purifiers increases, manufacturers are developing new technologies to improve their effectiveness and efficiency. One emerging trend is the use of ultraviolet light to kill bacteria and viruses. UV-C light has been used for decades to disinfect surfaces and water, and now it's being incorporated into air purifiers to provide an extra layer of protection against airborne pathogens.ย 

The integration of air purifiers into HVAC systemsย  allows for whole-house air purification and can be especially beneficial in commercial buildings, where multiple occupants share the same air supply. Some manufacturers are also developing smart air purifiers that can be controlled via a smartphone app, allowing users to monitor air quality levels and adjust settings remotely.

The growing use of air purifiers

The growing use of air purifiers is driven by the increasing awareness of indoor air pollution and its effects on health. Poor indoor air quality can cause or worsen respiratory problems, allergies, and other health issues. According to the Environmental Protection Agency (EPA), indoor air can be up to five times more polluted than outdoor air, and Americans spend an average of 90% of their time indoors.

Air purifiers can help to reduce indoor air pollution and improve overall air quality, making indoor spaces healthier and more comfortable. They can be especially beneficial for people with allergies or respiratory issues, as well as for those living in areas with high levels of pollution or wildfire smoke.

How long does it take for an air purifier to clean a room?

The time it takes for an air purifier to clean a room depends on several factors, such as the size of the room, the level of air pollution, and the type of air purifier being used. Generally, air purifiers can clean a room in a matter of minutes to hours, depending on the size of the room and the air purifier's capacity. For instance, a small air purifier may take 30 minutes to clean the air in a small bedroom, while a larger air purifier may take a few hours to clean the air in a large living room. It is important to choose an air purifier that is appropriate for the room size and the level of air pollution to ensure optimal performance. It is recommended to run the air purifier continuously to maintain clean indoor air quality.

Which is better: An air purifier or a humidifier?

Air purifiers and humidifiers serve different purposes, so it is not a matter of which one is better, but rather which one is more suitable for a specific situation.

Air purifiers are designed to remove impurities and contaminants from the air, such as dust, pollen, smoke, and other airborne particles. They work by drawing in air, filtering out the pollutants, and then releasing the clean air back into the room. Air purifiers can be helpful for people with allergies, asthma, or respiratory issues, as well as for those who live in areas with high levels of pollution.

On the other hand, humidifiers are designed to add moisture to the air to alleviate dry air symptoms, such as dry skin, nasal congestion, and sore throat. They work by adding moisture to the air through evaporation or ultrasonic technology. Humidifiers can be particularly helpful during the winter months when the air tends to be drier due to indoor heating.

Therefore, the choice between an air purifier and a humidifier depends on the specific needs of the user. If someone is suffering from respiratory issues or living in a polluted area, an air purifier would be a more suitable option. On the other hand, if someone is experiencing dry air symptoms, a humidifier would be a better choice. Some models combine both functions, serving as air purifiers and humidifiers simultaneously, providing the benefits of both devices in one unit.

Factors to Consider When Choosing an Air Purifier

  • Room size
  • Type of air filter
  • Maintenance requirements
  • Noise levels
  • Cost

Benefits of Air Purifiers in Improving Indoor Air Quality

  • Reduction in air pollution
  • Prevention of respiratory problems
  • Reduction in allergy and asthma symptoms
  • Improved sleep quality
  • Protection from harmful gases and chemicals


As the importance of indoor air quality continues to grow, so does the demand for air purifiers. With new technologies and features emerging, air purifiers are becoming more effective and efficient at removing harmful particles from the air. Whether it's for personal use or for commercial settings, air purifiers can help to improve indoor air quality and create healthier and more comfortable indoor environments.
