coway airmega air purifier Eco Mode

A True Moneysaver — Eco Mode

Designing for the future

One of the most persistent issues in modern engineering is energy consumption. For Coway, it’s a core tenet that drives our research and development. When you develop a product to do the same job as its predecessor, but with half the energy, you know you are building a sustainable future. Consequently, the air you breathe can now be free from harmful contaminants like agricultural runoff, VOC’s, bacteria and viruses, without drastically raising your energy use.


Set it and forget it

The feature, Eco Mode, 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 — as you don’t have to worry about manually operating your Airmega, if you are temporarily absent from your 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, beneficiaries will 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 AP-1512HH 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 its space. When compared to Wirecutter's recommendation of staying on medium (assuming LV2), you could save up to a range between $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. However, the AP-1512HH is fundamentally a low-energy consuming appliance, thus Eco Mode will not likely generate a substantial dollar amount in savings. Those users who are accustomed to running the unit on fan speed 3 for an abnormal duration will reap the most value from implementing Eco Mode into their daily routine.
