DEPARTMENT of Health (DOH) Regional Director Dr. Adriano Suba-an on Tuesday, November 3, said there is no enough data nor research on the effectiveness of using air humidifiers or purifiers to prevent the spread of the novel coronavirus.
He added that more data is needed to validate the claims of its effectiveness.
On October 30, the DOH released a statement clarifying that they are not endorsing the use of necklace air purifiers, which claim to kill bacteria or viruses or protect from Covid-19.
"While these devices do not pose any harm, the DOH currently does not recommend using these devices due to lack of evidence of efficacy," the DOH stated.
The DOH emphasized that wearing necklace air purifiers does not replace the need to practice minimum health standards. Mask wearing, handwashing and physical distancing remain to be the best protection.
The public is also reminded to stay vigilant and follow accurate public health advice and guidance from the DOH, the World Health Organization and other reputable health institutions.
Suba-an, for his part, said if air purifiers or humidifiers can help people psychologically, then they can continue to use them.
