How Much Electricity Does an Air Purifier Use?

Air purifying devices have been around for many years now, these devices suck in air and remove all kinds of airborne particles that pollute the air and make it harmful to breathe, they’ve been in use in commercial areas for quite some time and are now starting to gain popularity in residential and personal use as well. A lot of people are interested in these appliances, but one of the most commonly asked questions related to these appliances is that how much electricity does an air purifier use?

More and more people are steadily becoming conscious about their health and are taking measures to lead healthier lives, this trend has resulted in a lot of people considering getting air purifiers for their homes. However since these appliances have just recently become popular for home use, people don’t know a lot about them and are hesitant to buy them, one of the most common questions that people have about air purifiers is that how power hungry are they?

Whenever someone buys an appliance for their home they choose a product based on its characteristics, one of the major characteristics being power consumption, a significant percentage of any residential electricity bill consists of energy consumed by appliances, and electricity doesn’t come cheap. So when you’re planning on buying an air purifier, you would want to know whether these devices consume as much electricity as an air conditioner or an electric heater, or do they consume less. It’s also good to know that for every energy dollar being consumed are you getting efficient and effective air filtration or not.

Air purifiers come in two types; air purifiers with replaceable filters through which air passes to get cleaned and filter-free air purifiers that make use of ionizing technology to remove airborne pollutants from the air. These appliances come in many different sizes as well, all of which can be categorized into large air purifiers that are designed to operate in large interiors such as office spaces and big homes, medium sized air purifiers that are better suited for medium to small sized homes and small air purifiers that can be carried around to provide users with personal air purification.

It goes without saying that larger air purifiers consume more power, they’re extremely efficient in larger spaces but shouldn’t be used in smaller rooms since that will significantly decrease their air purifying to energy consumption ratio. The opposite goes for medium sized purifiers, they’re perfect for home interiors but in larger spaces would consume more energy and clean lesser air. Small sized air purifiers are better for personal use, they consume little electricity and are designed to be placed close to the user since they can only clean the air present immediately around them.

The most decisive factor in air purifier energy consumption is the type of air purifier, filter using air purifiers tend to use more power since they need powerful suction to pull air through the dense filters they use. Air purifiers that use HEPA filters are especially power hungry since HEPA filters are pretty thick, you should expect to see a power consumption of 30 to 350 Watts in filter air purifiers, the power consumption varies according to size and the setting on which an air purifier is being used.

Ionizing air purifiers consume a lesser amount of energy since they don’t require powerful suction, but the problem with them is that they aren’t as efficient at filtering air as other air purifiers and also produce ozone, which is an indoor air pollutant and can be bad to breathe in. Overall, air purifiers do consume more energy than your average pedestal fan, but if you buy the right kind of air purifier and use it in a proper manner then its power consumption can become efficient, and its energy cost to cleaning ratio can make the device worth buying.

Some air purifiers combine ionizing technology with filtering to provide even more effective cleaning, but these devices consume even more energy, making them unsuitable for most people.

You can even find air purifiers nowadays that are designed to be efficient at energy consumption, by making use of sensors they are able to gauge how much pollutants are present in the air and how much power does it need to do its job effectively. Such air purifiers consume electricity in a much smarter manner and are set to become more popular in the near future as the demand for air purifiers is steadily on the rise.
