What people are saying
Many discussions highlight the remarkable filtering capacity of the human nose, emphasizing its ability to filter particles down to 0.5 microns and comparing it to N95 masks, with some posts questioning or reinforcing this point through references to studies and particle sizes. The tone varies from supportive to skeptical, with a few participants critically analyzing the implications for mask efficacy, thereby showing a balance of agreement and engagement, while the overall focus underscores the nose’s critical role in respiratory health.
Most comments agree that the nose is an effective filter, comparing it to masks and emphasizing its role in filtering small particles.
The discussions are highly engaging, with many tweets referencing specific particle sizes and implications for health.
There is moderate depth, as some posts quote research findings or challenge assumptions about masks and aerosol transmission.
The conversations reflect a recognition of the importance of nasal filtration in health, though some skepticism and debate indicate it’s not universally accepted.
Abstract in brief
- The report explains how the human nose filters inhaled particles, with larger particles (>3 microm) being deposited mainly in the front part of the nose, while smaller particles (<0.5 microm) tend to pass through to the lower respiratory tract.
- The nose’s filtration ability is influenced by its internal structures like the nasal valve and turbinates, which affect airflow and particle deposition.
- Understanding how the nose filters particles can impact nasal surgeries like septal surgery and rhinoplasty, as changes to nasal structures can reduce the nose's capacity to filter airborne particles.]

@DelthiaRicks 3/ Based on air volumes alone, I'd speculate the opposite I'd speculate that most small aerosols (and virions) pass through the nasal cavity. Indeed, see: https://t.co/pCP85zsTYF

@mikolaj_kam Jest to dokładnie taka sama hipoteza jak tak, ze maseczki rozbijają krople z wirusem do rozmiaru, który nasz nos nie jest w stanie przefiltrować i zwiększają tym samym prawdopodobieństwo infekcji (poniżej 0.5um) https://t.co/1GHVkJCpSO
