Costs to Run Air Purifiers: The Easiest Formula & Top 3 Cost-Effective Tips

0 comments

Air purifiers normally use ONLY a little electricity. The power of home air cleaners is generally around 3 watts to 60 watts. For some energy-saving air purifiers, it only costs $5 per year!

In this post, you'll learn about the easy formula to calculate the running costs, the overall table, as well as tips on how to save energy on air purifiers.

Part 1. Almighty Formula to Calculate Running Costs of Air Purifiers

Formula:

[(Air Purifier Power X 24)/1000 kWh] X Electricity Cost/kWh = Cost Per Day

Take Purivortex 201B as an example. The power of this small air purifier is 6 W (maximum fan speed). The electricity cost per kWh is $0.256. Let's take the 2 numbers into the formula:

[(6 X 24)/1000] X 0.256 = $0.03/day

That means running this small air purifier all the time for 1 day only costs you $0.03, $0.2 for 1 week, $0.9 for 1 month, and $10.8 for 1 year!

You would not run an air purifier 24/7. So in reality, you would only pay $5 - $8 each year for running 201B.

According to the table below, air purifiers are very cost-effective to run. The cost of running a model like 201B is even lower than the cost of running an LED bulb.

Note: The only maintenance cost for air purifiers is the replacement filter. It is recommended to replace the filter every 3-6 months. Filter costs around $13 to $30 based on the size of the air filter and its technology.

Part 2. Top 3 Energy-Saving Tips: 100% Effective

The below 3 ways have been tested by our engineers. These ways can truly save power when running air purifiers at home or office.

Way 1. Open the Auto Mode

If your room's air quality is very clean, you don't need to run your air purifier at maximum or medium fan speeds because it will waste energy. To save energy, you can open the auto mode and let it adjust the fan speed automatically based on the air quality.

Way 2. Use Lower Fan Speeds

Normally, there is no need to keep your device at the highest speed 24/7 as lower speeds can purify the air too without using too much power.

For example, when you arrive home, you can set the fan speed to its maximum, and then lower it once the air quality is satisfactory.

Way 3. Choose the Right Air Purifier

If your house size is larger than 400 ft2, you should get a large air purifier that can cover over 400 ft2. Small-sized air purifiers will suffice if your house is smaller than 200 ft2.

Check the wattage of the machine in its description before buying one because air purifiers with higher wattage consume more energy.

Part 3. Quick Answers to Questions of Air Purifiers' Running Costs

Q1. Should Air Purifiers Run 24 Hours a Day?

A1. Yes, you should run it 24/7 for your health. Air purifiers should run continuously (24 hours a day) for best results. Since rooms are never actually airtight, airborne pollutants always tend to reenter.

Q2. Does an Air Purifier Use a Lot of Energy?

A2. Nope, dear, it doesn't. In comparison with other household appliances, an air purifier does not consume much electricity. Small air purifiers use about 30 kWh per year, while other household appliances, such as a television, use about 1,000 kWh per year.

Q3. Does Using an Air Purifier Put on a Load on the Electricity Bill?

A3. Oh, definitely no, mate. The air purifier has barely effects on your electricity bill. The small-size air filter costs you less than $10 per year. However, the larger the size, the pricier the payment.

It is recommended to get an air purifier with range of 6-60 watts of power for home use. For example, an air purifier that can clean small rooms (up to 215 ft2) costs less than $5 per year.

Q4. How Much Does It Cost to Run an Air Purifier?

A4. The running cost of an air cleaner is around $6 to $100 per year based on the size of the air purifier and the electric rates of your city.

For example, you have a large-sized air purifier that can cover 1,000 ft2 rooms costs less than 70$ per year.

Q5. Are Air Purifiers Expensive to Run?

A5. No. Air purifiers are not expensive to run. Normally, energy costs are usually less than $100 per year even it's a huge tank air cleaner.
