How Much Does It Cost to Run an Air Purifier in the UK?

Pennies per Day
Modern air purifiers are incredibly efficient. Most use DC motors that consume between 5W and 40W. Even running a Levoit Core 300S (which draws about 7W on sleep mode) 24 hours a day, 7 days a week, would use roughly 61 kWh per year. At current UK rates (approx 27p/kWh), that is around **£16 per year**.
The Hidden Cost: Filters
The electricity is cheap, but the filters are the real cost. A standard HEPA filter lasts 6-12 months. - **Budget Models:** Filter costs ~£20-£30 per year. - **Premium Models:** Filter costs ~£60-£90 per year. Always check the replacement filter price before you buy the unit.
