Running-cost calculator
How much does an air purifier cost to run in Spain?
Air purifiers with HEPA filters draw just 15 to 100 watts on standard settings, so even running long hours they add little to a bill. Models with an auto mode adjust fan speed to air quality and use less on average. They've become more popular in Spain with dusty calima episodes, summer wildfire smoke and pollen. Set the hours to how long it runs each day to see the (small) running cost.

Frequently asked questions
How much does an air purifier cost to run in Spain?
Very little — a 40 W unit run 12 hours a day costs under €0.10 a day, around €3 a month, at an all-in rate near €0.19/kWh.
Is it expensive to run an air purifier all day?
No. Even continuous use is cheap because the wattage is low. Auto mode reduces it further by slowing the fan when the air is clean.
