# Fungus in ACs poses health risk during monsoon 2026-08-09T04:50:17+00:00 | Health & Science | Indian Opinion Desk Corroboration: 1 independent outlet Business Today reports that monsoon moisture trapped inside AC filters and coils creates a breeding ground for fungus, making the appliance a hidden health risk. Dust, bacteria and fungal particles can circulate with cooled air, especially when filters are not cleaned regularly. The report warns that neglected maintenance can cause respiratory discomfort and unpleasant smells, beyond just reduced cooling efficiency. The dry mode feature available on many modern ACs can help reduce excess humidity during rainy days. Business Today advises that regular filter cleaning and switching to dry mode are simple steps to maintain indoor air quality. The monsoon season is a critical time for AC hygiene, as increased humidity encourages microbial growth when filters are dirty. ## Coverage - businesstoday.in Tags: AC, fungus, health, indoor-air-quality, maintenance, Monsoon Canonical: https://indianopinion.org/fungus-in-acs-poses-health-risk-during-monsoon/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
