Does an Air Purifier Use a Lot of Electricity?

When buying an air purifier for the first time, you might have many questions about them, so you check several on Walmart for air purifiers. One of the most common questions that first-time buyers ask is “does an air purifier use a lot of electricity?” To answer this question, we’ve done some research on air purifiers, let's get into it.

What is an Air Purifier?

Before we get into how much electricity they consume, what exactly is an air purifier? An air purifier is used for cleaning air to improve the air quality index.

How Does an Air Purifier work?

An Air purifier cleans the air through several steps. The air from the room is sucked in the purifier. This air then passes through a filter that has various sieves. These fine sieves filter the air circulating in the room. The finer the sieve is, the cleaner the air will be. They sanitize the air from pollutants, toxins, and allergens. Making the air around you and your family cleaner.

How Much Does an Air Purifier consume?

Now that we know what an air purifier is, let's find out its electricity consumption. Air purifiers are energy-friendly devices. They consume anywhere from 20W to 200W. Don't be alarmed, only the ones that are running at max speed consume 200W. A room air purifier that you own in your home will consume hardly as much as 30W. That is because it will be working at lower speeds. In comparison to this, typical mobile chargers nowadays consume 30W.

How to Calculate Consumption Cost per Month?

If you own a 150W air purifier that purifies the air of your whole house, let's find out its consumption. If a 150W air purifier runs for an hour, it consumes 0.150kW electricity per hour. If you plan on running your air purifier for 12 hours a day, then,

0.15kWh x 12 hours = 1.8kWh every day

And then,

1.8kWh x 30 days = 54kWh every month.

Then you’ll get an average of 54kWh per month.

Now that we’ve calculated a 150W air purifier’s consumption, let's try to get an estimate on your electric bill. Electricity rates are different in one state from another. That's why we’re assuming a per kWh cost that is near the average. That is, 12 cents per kilowatt-hour. When you multiply 54kWh with 12 cents, you get,

54kwh x 12 cents = $6.48

This shows us that if you use a 150W air purifier in your home, then it would add up to an average of $6.5 to your electric bill. Now, remember, these calculations are based on assumptions, but these assumptions are not far from reality. These calculations should give you an idea of how much a typical air purifier cost.

Now You Know!

We hope you’ve found an answer to your question. Air purifiers don't consume that much. But if you compare their consumption to the functionality of how they clean the air, the consumption cost seems nothing.
