How much electricity does an air purifier use?

Are you worried about how much electricity your air purifier consumes?

An air purifier can be a great way to improve indoor air quality. Maybe you want to buy it or have recently bought it and want to know how much electricity it consumes. My article below will answer this question and tell you how to save electricity.

As with any household appliance, the main thing to look at to determine how much electricity it consumes is power; then you need to consider how long it has been in use. The power of an air purifier typically ranges from 8W to 130W and costs approximately $1.50 to $12.50 for one month of continuous operation. It may not be much if you don't use it very often.

Air purifiers

Air purifiers come in many types, sizes, and shapes and have been used for different periods of time. For this reason, it is not possible to give an exact figure for electricity consumption that will be the same for every air purifier.

You will need to check your air purifier for certain information (see next section) and your electricity bill if you want to know how much it costs.

How much electricity does an air purifier use?

To accurately calculate how much electricity your air purifier uses, find or calculate the following:

• Air purifier power
• The average number of hours you use an air purifier each day.
• Total number of days the air purifier was used during the billing period (usually one month)
• Electricity tariff (per kW)

Generally, the lower the wattage of an air purifier, the less electricity it will use, and the higher the wattage, the more it will use. But we will also determine the cost of the electricity it uses below. Once you have the above four pieces of information, use the calculation below to determine how much your air purifier will cost during the billing period:

Power / 1000 X Number of hours of use X Number of days of consumption X Electricity tariff.

If you use your air purifier for a different number of hours each day, or only on certain days, you can ignore the number of hours and days in the above calculation and instead multiply by the total number of hours used during the month.

Low Power Air Purifiers

Air purifiers typically draw between 8 watts and 130 watts and cost about $0.50 to $12.50 for one month of continuous operation. Even in standby mode, they can consume up to 1.5-2 watts (usually about 0.2 watts). Energy efficient air purifiers use less power, while older air purifiers tend to have higher wattage.

Here are some low power air purifiers that consume no more than 50 watts:

• Coway Airmega AP-1512HH (15 W)
• Air purifier Xiaomi MI 3H (38W)
• Hathspace HSP001 (40W)
• Levolt Core 300 (45W)
• Rabbit Air Minus A2 (48W)
• Okaisou AirMax 8L (50W)

AttentionA: There are many other low power air purifiers. We have provided only a small selection.

If your air purifier draws more than the above, especially those that use more than 130 watts, you may notice a difference in your electricity bill. Among the highest power consuming air purifiers you should avoid are the IQ Air Health Pro Plus (215W) and Dyson HP04 (up to 600W).

Other considerations

Power is not the only factor when buying an air purifier.

The same brand can have more than one model. Always check the wattage, not the brand. Plus, a low-powered air purifier can mean you have to compromise on quality and features.

A better approach may be to find the right balance between energy savings by purchasing an energy efficient air purifier and acceptable quality and desired performance. Also, a higher power air purifier may need to be powerful enough to cover the area in which you use it or will be using it.

If power consumption is not a concern for you, pay attention to things like appearance, quality, features, parts availability, service, etc.

Save energy with an air purifier

To save on the electricity used by the air purifier, there are a few things you can do:

• Buy an energy-efficient Air Purifier certified by Energy Star.
• Use the air purifier for a limited number of hours instead of leaving it running all day.
• Set the air purifier fan to a slower setting.
• Change the air filter regularly to keep the air purifier from overworking.
• Turn off the air purifier instead of leaving it on standby for a long time.

Summing up

The main factors that determine how much electricity your air purifier uses are its power rating and how long it is used. We also showed you how to calculate the exact cost of electricity and ways to save electricity when using an air purifier. If you need it, we advise you to buy an energy efficient model, but also take into account other aspects such as quality and features that you may need.
