In　recent　years,　repeated　outbreaks　of　airborne　viruses　have　normalized　human　coexistence　with　these　viruses.　The　complex　turbulence　and　vortices　generated　by　different　fan　types　and　operation　modes　affect　virus　removal　effectiveness.　This　paper　reviews　the　potential　impact　and　actual　effectiveness　of　different　fans　in　mitigating　indoor　virus　transmission,　highlighting　their　advantages　and　limitations.　Downward　rotating　ceiling　fans　can　rapidly　dilute　virus　concentration　(21-87%)　in　the　breathing　zone　due　to　jet　cores,　with　efficiency　depending　on　rotational　speed　and　particle　diameter.　However,　the　reprocessing　problems　of　large　particles　being　deposited　on　surfaces,　and　small　particles　settling　and　rebounding　into　the　air　remain　unresolved.　Upward-rotating　ceiling　fans　do　not　contribute　to　indoor　virus　removal.　Exhaust　fans　generate　a　negative-pressure　environment,　which　helps　expel　viruses　quickly.　But　improper　vortex　zones　can　increase　virus　retention　time　16-40　times.　Air-apply　fans　effectively　dilute　and　transport　viruses　only　when　delivering　airflow　exceeding　0.5　m/s　directly　into　the　breathing　zone.　Additionally,　combined　fan　strategies　remain　underexplored,　despite　potential　benefits.　This　review　underscores　the　need　for　standardized　definitions　of　particle　removal　effectiveness　and　calls　for　further　research　on　how　climatic　conditions　and　thermal　comfort　influence　fan-based　interventions.
