Problem Statement
SIZE OF CORONAVIRUS: 50 nm to 140 nm.
SIZE OF RESPIRATORY DROPLETS: Typically 5-10 micrometers (µm) in length; therefore, it can be inferred that an individual who ingests, inhales, or is otherwise exposed to SARS-CoV-2 positive respiratory droplets can be exposed to hundreds or thousands of virus particles which increases the probability of infection.
[1]. Difficulty in breathing
[2]. Ineffective sound flow
[3]. Bad grip- Entry of impure air, fogging of glasses and sliding down of masks
[4]. Thread- breaking/ loosening; trouble to ears
[5]. Pressing need for double masks for better filtration of air
[6]. Development of facial skin lesions or worsening acne, when used frequently for long hours
[7]. Difficulty wearing a mask in hot and humid environments
[8]. Contamination of the mask due to its manipulation by contaminated hands
[9]. Contamination that can occur if masks are not changed when wet, soiled or damaged.
[10]. Cleanability and reusability
[11]. High-filtration masks, which are a cut below N95s, can block much of the transmission but are not as effective against aerosols.
