In short: use the unit manual and observed fouling, not a fixed weekly or monthly interval.
Greasy kitchens, road dust, building work, pollen and leaves require more frequent checks. Inspect often after installation, record whether fins are clean or blocked, then adjust the interval.
If grease or dust returns quickly, improve the source, location or approved filtration. Do not add a random mesh that restricts airflow.
Cleaning frequency by environment
| Environment | Cleaning frequency | Why |
|---|---|---|
| Clean indoor air (air-conditioned space, sealed plant room) | Monthly | Slow dust accumulation only |
| Industrial / commercial kitchen | Every 2 weeks | Airborne grease bonds dust to the fins |
| Outdoor or dusty location | Weekly | High particulate load, pollen, leaves |
| Near a road or active construction | Weekly during exposure | Fine dust and debris clog fins rapidly |
Why grease matters most
In a kitchen, airborne grease forms a sticky film that traps dust and is far harder to remove than dry dust alone. A dry indoor coil can be brushed clean; a greasy one usually needs a coil-cleaning solution to break the film. That extra effort — and the speed at which the film builds — is why the kitchen interval is half the clean-air interval.
Treat the table as a floor, not a ceiling. If you open the unit at the scheduled interval and find the fins already bridged with dust or grease, shorten the cycle until the coil is reasonably clean between visits.
