Air purifiers are becoming increasingly popular as people look for ways to improve the air quality in their homes. But how much do they cost to run?

To find out, we tested more than 100 latest air purifiers to see how much they cost to operate. We found that most air purifiers use very little electricity, so the daily average cost is only $0.05 to $0.50 per day. However, if you run your air purifier on stand-by mode, it can cost up to 2 dollars per year.

how much does it cost to run an air purifier


When it comes to air purifiers, one of the most important considerations is cost. Unfortunately, many people don’t realize how much these devices can actually cost to run.

In order to make an informed decision about whether or not to purchase an air purifier, it is important to understand the potential expense involved.

Based on our testing, we’ve found that the cost of running an air purifier can range from $0.05 to $0.50 per day, or $2 to $150 per year, if your air purifier is working properly. Of course, this will vary depending on the size of your room and the type of air purifier you choose. 

The cost of running an air purifier will depend on several factors, including the size of the room, the type of air purifier, and the climate. In general, however, you can expect to pay between $50 and $150 per year to run an air purifier.

The most expensive air purifiers to run are typically those that use ultraviolet light or ozone generators, which can increase your energy costs.

If you have a very small room, your monthly cost can be as low as 2 dollars. However, if you have a larger space, such as 500 square feet or more, your air purifier will use more power and your monthly cost can be as high as 7 dollars.


In the United States and United Kingdom, air purifiers are becoming increasingly popular as people look for ways to improve the quality of the air in their homes.

However, some people worry that these devices may use a lot of electricity. While it is true that air purifiers do use some energy, they are generally very efficient and use far less power than many other common household appliances.

In fact, most air purifiers only use about as much electricity as a standard light bulb. As a result, they are an affordable way to help improve the air quality in your home without significantly increasing your energy usage.

10 Useful Tips to Reduce the Cost of Running an Air Purifier

To save on the cost of running an air purifier, there are several tips to consider:

  1. Choose an energy-efficient air purifier. Look for an air purifier with an Energy Star label, which indicates that it meets strict energy efficiency standards set by the Environmental Protection Agency.
  2. Set the air purifier to the lowest setting possible. Most air purifiers have multiple settings, and using the lowest setting will reduce energy consumption and save money on electricity costs.
  3. Change the air filter regularly. A clogged air filter can reduce the efficiency of the air purifier and cause it to use more electricity.
  4. Use a high-quality air filter. A high-quality air filter will last longer and be more effective at removing pollutants from the air, reducing the need to run the air purifier as frequently.
  5. Place the air purifier in a central location. This will ensure that the air purifier can clean the air in the entire room, reducing the need to run multiple air purifiers.
  6. Use a HEPA filter. A HEPA filter is the most effective type of air filter, removing 99.97% of particles from the air.
  7. Close windows and doors when running the air purifier. This will help to prevent outdoor air from entering the room, allowing the air purifier to clean the air more effectively.
  8. Use a smart air purifier. A smart air purifier can be controlled remotely, allowing you to turn it off or adjust the settings when you are not home.
  9. Use a smaller air purifier in smaller rooms. A larger air purifier will use more electricity and may not be necessary in a smaller room.
  10. Consider purchasing an air purifier with a timer. This will allow you to set the air purifier to run only during certain hours, reducing the amount of electricity it uses.

Philips Air Purifier Power Consumption

I was delighted to discover the Philips air purifier. Not only does it effectively clean the air in my home, but it also runs at a very low power consumption of just 20 watts – the equivalent of a standard light bulb.

One of the things I appreciate most about the air purifier is that it uses minimal power even when on standby mode. In fact, it has a stand-by power consumption of less than 0.5 watts, which is barely any power at all.

This means that I can leave the air purifier running all day without worrying about it significantly increasing my electricity bill.

Another aspect I appreciate is the voltage of the air purifier. It runs on 220-240 volts, which is the standard voltage in most homes.

This means that I don’t have to worry about purchasing any additional equipment or making any modifications to my home’s electrical system in order to use the air purifier.

I’ve been using the Philips air purifier for a few months now and it has been a great addition to my home. Not only does it help keep the air clean and fresh, but I also feel good knowing that it’s not using a lot of power.

If you’re looking for an energy efficient air purifier, I highly recommend checking out the Philips air purifier.
