Air purifiers typically do not consume a lot of electricity, especially when compared to larger appliances such as air conditioners or heaters. The power consumption of an air purifier generally depends on its size, the features it offers, and the manufacturer's specifications. Most air purifiers consume between 50 to 100 watts per hour when they are in operation, which is relatively low. It is also important to consider that many models have energy-efficient settings and operate on low power during normal use. This means that not only do air purifiers help maintain a cleaner indoor environment, but they also tend to be cost-effective in terms of electricity consumption.
