Many people are concerned about the electricity consumption of air purifiers and how it compares to other household appliances.
In this article, we will explore the energy usage of air purifiers and compare them to different household items.
Do Air Purifiers Use Lots of Electricity?
The electricity consumption of air purifiers can vary depending on several factors, including the size and model of the unit, the fan speed settings, and the duration of operation.
On average, most air purifiers consume between 50 to 200 watts per hour.
It is important to note that air purifiers are typically designed to run continuously for long periods, especially in areas with poor air quality.
However, some models come with energy-saving features, such as timers or sensors that adjust the fan speed based on air quality, helping to reduce energy consumption.
Air Purifier Electricity Consumption Comparison with Different Household Items
Let’s compare the electricity consumption of air purifiers with other common household appliances:
| Home Appliances | Electric Consumption (watt) |
| LED Light | 10 |
| Microcwave | 1000 |
| Kettle | 2200 |
| Toster | 2000 |
| 65″ TV | 200 |
| 600L Fridge | 200 |
| Laptop | 100 |
| Phone Charger | 30 |
| Modem(Router) | 50 |
| Washing Machine | 2500 |
| Dishwasher | 2500 |
| Clothes Dryer | 3500 |
| Spa | 8000 |
| EV Charger | 7000 |

It is important to note that these comparisons are meant to provide a general understanding of the relative energy consumption of air purifiers compared to other household items. The actual energy usage may vary depending on the specific make and model of the appliance.
1. Air Purifier vs. LED Light Bulb
An average LED light bulb consumes around 10 watts per hour. This means that an air purifier running at 100 watts per hour would use slightly more electricity than a single LED light bulb.
2. Air Purifier vs. Laptop
A laptop typically consumes around 50 watts per hour. In this case, an air purifier running at 100 watts per hour would use twice as much electricity as a laptop.
3. Air Purifier vs. Refrigerator
A refrigerator is one of the most energy-consuming appliances in a household, consuming around 150 to 300 watts per hour.
An air purifier running at 100 watts per hour would use less electricity than a refrigerator.
4. Air Purifier vs. Air Conditioner
An air conditioner is known for its high energy consumption. Depending on the size and efficiency, an air conditioner can consume anywhere from 500 to 3500 watts per hour.
In comparison, an air purifier running at 100 watts per hour uses significantly less electricity.
5. Air Purifier vs. Hair Dryer
A hairdryer typically uses around 1200 to 1800 watts per hour. This means that an air purifier running at 100 watts per hour uses significantly less electricity than a hair dryer.
Tips for Reducing Air Purifier Electricity Consumption
If you are concerned about the electricity consumption of your air purifier, here are some tips to help reduce energy usage:
Use energy-saving features: Look for air purifiers that come with energy-saving features such as timers or sensors that adjust the fan speed based on air quality.
Operate at lower fan speeds: Running the air purifier at lower fan speeds can help reduce energy consumption while still providing effective air filtration.
Keep the filters clean: Regularly clean and maintain the filters in your air purifier to ensure optimal performance and energy efficiency.
Consider the room size: Choose an air purifier that is appropriate for the size of the room you want to purify. Using an oversized unit can result in unnecessary energy consumption.
Turn off when not needed: If the air quality in your area is relatively good, consider turning off the air purifier when it is not needed to further reduce energy consumption.
