Due to the pandemic, wearing masks for long periods of time has become the norm. Especially indoors, wearing a mask is compulsory, and people are required to wear it for several hours. Wearing masks for an extended time, especially in the summer, increases the temperature and humidity inside the mask, which can be uncomfortable.
I used a custom-developed data recording device to study various types of masks. It measures real-time changes in temperature, humidity, and CO₂ concentration in the air. A prototype mask with fans was also developed to attempt to reduce the increase in temperature, humidity, and CO₂ concentration inside the mask and compared against the commercially available masks.
