A "SECRET WEAPON"

SAFER

HUMIDIFIERS

Qualifying note: This page includes some research to-date on humidity's impact on COVID-19 contagion. However, discoveries are ongoing and will reinforce some early assumptions, and offer correction for others.

During the COVID-19 pandemic, it is not possible to be entirely safe from contagion when multiple people gather.

​

However, there are some low-effort ways you can make the environment significantly safer, whether at a family gathering or group event, or in a workplace or shared household.

We must combat SARS-CoV-2 particles
IN THE AIR

in addition to on surfaces.

We are learning that the coronavirus is spread through not only droplets (such as from coughs), but also through aerosols -- fine mists of normal breathing.

Common COVID-19 Contagion Control Methods

Organizations such as the Center for Disease Control and World Health Organization have given various helpful recommendations that help reduce the spread of the coronavirus.

Increase air flow and ventilation rates, but do not point fans directly from one person toward another

Make sanitizing hands and shared surfaces frequent and convenient

Always wear face masks over nose and mouth indoors, and when close to others outdoors

Practice 2 meters (6 feet) social distancing

Reduce size and frequency of group gatherings

Use portable air purifiers and air filters, or install larger types.

Limit the number of people in an enclosed area

Be aware that strenuous breathing from singing, exercise and loud talking increases aerosols in air

Dry winter air significantly increases coronavirus transmission in air, and decreases our bodies' resistance to infection. Humidifying air to optimal levels can have enormous benefit in your home and other locations.

Using Humidifiers

40-60%

During winter, unless a humidifier is used, the average humidity inside most buildings is only

is the ideal relative humidity for fighting infection in most indoor environments .

15-25%

Outside the body, SARS-CoV-2 is deactivated more quickly in dry air

​Particles are also made heavier, so they drop out of air more quickly.

Coronaviruses are tiny and can float in the air for up to several hours when dry. When they become connected to other particles or water vapor, the combined particle is heavier, so they fall out of the air more quickly.

Supercomputer modeling showed that at 30% relative humidity, ore than TWICE as many exhaled aerosols float in air, compared to when humidity is maintained at 60% or higher.

​Helps the body fight COVID-19

Moisture helps the hair-like "cilia" throughout our respiratory system move more freely to help sweep infectious particles out of our noses, throats and lungs.

Other mechanisms are being studied to increase our understanding of why mid-level humidity levels have been shown to be so beneficial in helping our immune systems.

In addition to portable room humidifiers, personal-size humidifiers are available that can be used even in a car or at a workstation. Whole-house humidifiers can also be of benefit.
