Figures are indicative estimates for illustration only, based on typical airflow-efficiency improvements of 20–30%. Actual savings depend on equipment, occupancy and tariffs. Book a free assessment for a tailored projection.
Restricted airflow forces your plant to overwork
Relative HVAC energy use as filter resistance rises. A clogged filter can add roughly a quarter to running costs.
Dirty filters vs clean filters
Dirty Filters
- Up to 25% higher energy bills
- Restricted airflow & cold spots
- Strained motors & shorter equipment life
- Poorer indoor air quality
- More emergency call-outs
- Guest complaints & weaker reviews
Clean Filters
- Lower, more predictable energy costs
- 20–30% improved airflow
- Longer equipment lifespan
- Cleaner, healthier air
- Fewer breakdowns & call-outs
- Consistent comfort & happier guests
What a maintenance programme delivers
Lower energy. Lower carbon. Real ESG progress.
Every kilowatt-hour you don't waste is carbon you don't emit. A filter maintenance programme is one of the most cost-effective sustainability measures available to a hotel: no capital project, just disciplined upkeep.
We provide documented before-and-after data you can fold straight into your ESG and sustainability reporting, helping you evidence progress to owners, brands and guests.
