How much does a low energy air purifier cost to run
Most home purifiers use similar power to a fan on low or medium. On the lowest setting many cost only a few pence per night. Running them steadily on a lower setting often works better and costs less than blasting them on maximum for short bursts.
Can I improve air quality without using much power
Yes. Simple habits like opening windows for short bursts when outdoor air is cleaner, using extraction fans and keeping moisture under control with a dehumidifier all help. A low energy purifier then has less work to do.
