Health benefits of humidifiers

Humidifiers may benefit individuals who use computers. A 2017 study found that participants who looked at a computer screen for 1 hour while using a desktop humidifier reported their eyes felt less dry than those who did not use a humidifier.

Additionally, older research suggests that more humid environments reduce the infectivity of influenza viruses. The authors suggest that keeping indoor environments at 40% humidity or greater can significantly reduce the infectivity of this virus.

However, other research suggests that humidifier use, along with other factors, such as gas stoves and central air conditioning, are risk factors for asthma and allergies in children.

Health benefits of air purifiers

There is evidence that air purifiers can decrease the amount of fine particle matter inside buildings. A 2020 study found that while air purifiers do not have a clinically significant impact on improving health, they can improve air quality slightly.

Additionally, a 2018 study suggests that air purifiers may benefit older adults living in urban areas. Additionally, the researchers add that air purifiers can reduce the risk of high blood pressure in nonsmoking older adults. However, more research is necessary in this area.
