about
Hey there! I'm Taliyah, the creator of Auto Mask. In the year 2020, due to the coronavirus pandemic and California forest fires, I realized NO ONE is comfortable wearing a mask.
There are many problems:
1. Difficulty breathing
2. Wearing incorrectly
3. Non-hygienic mask practice
4. Injuries due to prolonged mask wearing
5. Mask off at critical moments
6. Not wearing at all!
​
Auto Mask is here to show that creativity and innovation can still go on! Read on to learn what's behind the creation of Auto Mask!
Auto Mask Creation
