May - June 2021

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.
