How much electricity does an air purifier use?

When you are running anything that involves motors or fans, there will always be the potential for electrical consumption.

The question is, what amount of electricity will your air purifier consume, and how much can you really afford to spend on it?

In this article, we will be answering this question.

And also, we will be sharing tips and tricks on ways you can reduce your electricity bill while using an air purifier.

Let’s get started.

How Much Electricity Does an Air Purifier Consume?

A standard air purifier uses about 50 W on average to operate. Energy Star reports that a standard air purifier that is turned on all day round consumes approximately 458 kWh per year.

This amount of energy is excessive for just air purifiers because even large refrigerators consume much less energy per year.

When compared to other appliances, a standard incandescent bulb usually runs at 60 W, and a new LCD television at 91.5 W.

However, it is recommended to use an energy-efficient air purifier.

This will help you to save electricity and cut the cost of having an expensive electricity bill.

How Much Does It Cost to Run an Air Purifier?

When it comes to measuring electricity, The kilowatt (kW) is the standard measurement.

Generally, one kW is equal to 1000 watts. And when electricity is consumed it is billed per kilowatt-hour (kWh). 

To calculate usage, you just need to divide the appliance’s wattage by 1000, then multiply by the number of hours the appliance was used.

For example, If you used a 50-watt air purifier for one hour today. We divide the air purifier’s wattage by 1000 (50 W/1000= 0.05 kW). 

This computation shows that you used .05 kW of electricity to keep the air purifier running for today.

If you keep using the air purifier for an hour a day for a month, you just need to multiply the kW usage per hour by 30 days.

Using the air purifier for 30 days will amount to 1.5 kW.

The total cost of electricity will depend on how much electricity rates are in your locality or country.

You need to multiply the monthly electrical consumption of the air purifier by the electricity rate in your area.

Take note, however, that electricity rates also depend on the price of generation, government taxes, and other operation costs.

Air Purifier Electricity Calculator

Below you will find a free air purifier electricity calculator.

If you know your wattage and electricity costs (you can find it on your bill) all you have to do is input it into the calculator.

And it will figure out the cost per day, monthly and yearly. Give it a try.

Air Purifier Electricity Consumption On Various Brands

Below, you will find an example on how much does it cost to power an air purifier. I took the most popular air purifier brands in the USA.

I also, based the table on a U.S average electricity rate of 13 cents per kilowatt-hour. And calculated the electricity if it was ran for 24 hours per day for 30 days per month.

Here is an idea on how much the monthly and yearly cost are per air purifier.

Factors Of An Air Purifier Energy Consumption

The wattage of the air purifier and the amount of time it is used in a day are crucial determinants of total electricity consumption.

In general, air purifiers use up a relatively low amount of power per hour. 

However, if you wish to use this appliance for extended periods, the cost that you will have to pay per month will be considerably higher.

Surely, all of us are looking to save some money while still getting continuous clean and fresh indoor air, right?

If you are wanting to reduce energy costs, when using an air purifier there are a couple more tips you can do to reduce the energy price and wattage.

Turning The Fan Speed To Low

Although most air purifiers do not consume a lot of electricity.

However, another way to reduce the energy cost even further is to set the fan on a low setting.

This will help the air cleaning device, not to overwork.

Replacing Air Filters

Dirty filters can cause the air purifier to work much hard than it normally does.

Resulting in higher energy costs. So to avoid this replace the filters when needed. You can do this by looking at the operation of the device.

Energy Star Certified

If you wish to run an air purifier all day without your bills getting too crazy, you must opt to buy Energy Star certified air purifiers to keep your electrical consumption in check. 

Summary – Do Air Purifiers Use A Lot Of Electricity?

Not all air purifiers are made equal.

Some are designed to perform excellently and take up a lot of electricity, while some can also perform greatly without using too much electrical power.

It is best to opt for Energy Star certified products if you wish for more cost-effective choices.
