Is Eco Mode a True Money Saver?
One of the most persistent issues in modern engineering is energy consumption. For us at Coway, sustainability is a core tenet that drives all of our research and development. When you develop a product that does the same job as its predecessor but with half the energy, you know you're building a sustainable future. And that's exactly what we've done with our Airmega line.
For those of us who don't want to drastically increase our energy use but do want the air we breathe to stay free from harmful contaminants (like agricultural runoff, VOCs, bacteria, and viruses), Airmega might just be for you.
With Eco Mode, Set It and Forget It
The Eco Mode feature is built into the Smart Mode setting of our Airmega air purifiers. This mode’s basic function is to cease operation in favor of saving energy once it is unneeded. If the current air quality level remains healthy and stable for 10 minutes in Smart Mode, the fan will stop. If 30 minutes pass or rising levels of air pollution are detected, the fan will automatically activate.
Save Energy, Save Cost
Smart Mode is a good default setting for your air purifier, since you don’t have to worry about manually operating your Airmega if you are temporarily absent from home. When air quality remains at stable, healthy levels, Eco Mode can conserve up to 75% of the energy that the fan would have otherwise consumed. With this mode, you'll be able to accumulate serious cost savings over time.
Based on our calculations using Los Angeles electricity costs ($0.25 per kWh), it would cost the Airmega Mighty specifically the following to run continuously for 30 days without stopping:
- LV1: $2.66 @ 3.7 Wh
- LV2: $6.08 @ 8.45 Wh
- LV3: $50.18 @ 69.7 Wh
When it comes to Eco Mode, the exact amount of savings varies widely due to the air quality of the space. When compared to Wirecutter's recommendation of staying on medium (assuming LV2), you could save up to $3-$5 a month (assuming you do not live in a desert or any other rural environment). This equates to a 75% decrease of the unit’s energy consumption, considering all possible variables.
Keep in mind that air purifiers like the Airmega Mighty are already fundamentally low-energy-consuming appliances. Because of this, Eco Mode won't likely generate a massive dollar amount in savings because the model is already so efficient. Still, users who are accustomed to running the unit on fan speed 3 for longer durations will reap the most value from implementing Eco Mode into their daily routine.

1Coway air purifiers have been proven to trap dust, pollen, dander, viruses and bacteria in the air based on KCL (Korea Conformity Laboratories) testing.They have been tested in a 30㎥ size chamber according to the Korea Air Cleaning Association standard (SPS-KACA 002-132:2022 Modified) to measure the 0.01㎛ size of particle removal rate. It was tested on maximum airflow speed in normal room temperature and humidity conditions. The performance may vary in the actual living environment of customers.

3Aerosol test conducted in a Biosafety level 3 laboratory with two Coway air purifier models, Coway Airmega 250 and 400 for removal of SARS-CoV-2 Aerosol by US based MRI Global, a not-for-profit laboratory and partner of US Department of Defense. The test was conducted in a 13.1ft3 chamber. Virus was aerosolized for 15 minutes and the product was turned on high for 2 minutes. Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19. Coway Airmega 250S and 400S are identical to the tested models and has equal performance with an additional mobile connectivity function.

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
