Diffuser Coverage & Running Cost
Every Airmate diffuser, side by side – room coverage, reservoir size and what it realistically costs to keep running each month.
| Device | Price | Coverage | Reservoir | Refill Interval | Est. Monthly Cost |
|---|---|---|---|---|---|

| Home Mate | LKR 25,000 | Up to 50m³ | 100ml | 4-8 weeks | LKR 2,250-4,500 |
| Pro Mate | LKR 35,000 | Up to 500m³ | 200ml | 4-8 weeks | LKR 2,250-4,500 |
| Duo Mate | LKR 40,000 | Dual-chamber coverage | Dual 50ml (100ml total) | 4-8 weeks per chamber | LKR 2,250-4,500 |

How this is worked out: Airmate scent oils come in 50ml (LKR 2,250) and 100ml (LKR 4,500) bottles – both work out to the same LKR 45/ml rate. At moderate daily use, most customers get 4-8 weeks from a bottle before it needs replacing, so a realistic monthly spend lands between LKR 2,250 and LKR 4,500 regardless of which diffuser you run it in. Running at a lower intensity setting, for fewer hours a day, or in a smaller room will stretch a bottle closer to the 8-week end; higher intensity or larger/open-plan spaces will use oil faster.
Frequently Asked Questions
Which diffuser is cheapest to run?
Running cost depends mainly on intensity setting and room size rather than the device itself, since all Airmate diffusers use the same scent oils at the same LKR 45/ml rate.
How can I make a bottle last longer?
Use a lower intensity setting, run the diffuser for fewer hours a day, and match the device to your actual room size rather than over-diffusing a small space.
Does the Hotel Collection cost more to run?
Hotel Collection oils are priced per 50ml bottle at LKR 9,500, higher than the standard Scent Oils range, reflecting their premium positioning rather than a different usage rate.
