Head-to-head
Levoit Core 400S-P vs Coway Airmega Mighty AP-1512HH: Nearly equal room ratings, remote scheduling or local Eco control
The short answer
Choose Core 400S-P if remote schedules and a narrow cabinet matter. Choose the Coway Mighty for onboard controls, a washable prefilter and an Eco mode that can stop the fan. Their published room ratings are almost identical at 4.8 air changes per hour, so coverage alone gives little reason to prefer either.

Treat room coverage as a tie
Published room ratings differ by less than 1%.
What this is based on
(361 − 358) ÷ 358 = 0.84%, with both ratings at 4.8 ACH.

What matters in practice
The differences that matter
Treat room coverage as a tie
Published room ratings differ by less than 1%.
How we reached this conclusion
(361 − 358) ÷ 358 = 0.84%, with both ratings at 4.8 ACH.
Shape can settle the choice
Levoit saves six inches of width but uses 1.2 inches more depth.
How we reached this conclusion
16.8 − 10.8 = 6.0 inches wide. 10.8 − 9.6 = 1.2 inches deep. Neither is smaller in every dimension.
Eco changes the filtration schedule
Coway's fan-stop behavior is a separate choice from app convenience.
How we reached this conclusion
The AP-1512HH manual documents Eco stopping after 30 clean-air minutes. Core 400S-P provides remote schedules. Neither feature demonstrates cleaner air in the buyer's room.
Try your real numbers
Will either purifier move enough clean air?
The result checks hard limits only. Preferences stay out of the calculation.
Levoit Core 400S-P
Fits these inputs231 CFM of verified clean-air delivery gives about 5.8 air changes per hour here. The 5 ACH target needs 200 CFM.
Coway Airmega Mighty
Fits these inputs233 CFM of verified clean-air delivery gives about 5.8 air changes per hour here. The 5 ACH target needs 200 CFM.
This uses maximum-speed, pollutant-specific CADR and a five-air-changes-per-hour target. Quieter settings deliver less clean air. It does not substitute raw airflow or a one-change coverage claim.

Meaningful differences
What changes the fit
| What changes | Levoit Core 400S-P | Coway Airmega Mighty | Why it matters |
|---|---|---|---|
| Room rating at 4.8 ACH | 358 sq ft | 361 sq ft | A three-square-foot difference is not a practical coverage upgrade. |
| Remote control | VeSync app and schedules | No Wi-Fi on AP-1512HH | Choose based on whether remote access is useful. |
| Clean-air response | Automatic fan adjustment | Eco can stop the fan after 30 clean-air minutes | Stopped operation differs from continuous low-speed filtration. |
| Cabinet width and depth | 10.8 × 10.8 in | 16.8 × 9.6 in | Levoit is narrower while Coway is shallower. |
| Rated power | 38 W | 77 W | These ratings do not measure actual savings at matched airflow. |
| Prefilter upkeep | Clean the outer prefilter without washing the main filter | Separate washable prefilter | Follow each filter's care instructions. |
What you give up
Every choice has a cost
If you choose Levoit Core 400S-P
- No Coway-style Eco fan-stop behavior is established
If you choose Coway Airmega Mighty
- Its 16.8-inch width takes more space along a wall
Recommendation switch
The decision flips if...
Remote operation is essential
Choose Levoit Core 400S-P. Only Core 400S-P provides it in this pair.
A separate washable prefilter is essential
Choose Coway Airmega Mighty. The Mighty has that maintenance feature.
What matters in practice
How to make the call
Do not pay for a negligible area difference
The two current ratings address almost the same room size. A 358 versus 361 sq ft label should not drive the purchase. Cabinet fit and controls create much clearer differences.
Decide how often you will change settings
Core 400S-P is useful when you want to start or schedule it from another room. The Mighty suits a fixed daily routine with local controls. Its Eco mode can pause the fan, which may be unwanted if you deliberately prefer continuous filtration.
Plan filter maintenance
Coway separates the washable prefilter from the carbon and HEPA stages. Levoit's outer prefilter is cleaned as directed without washing the combined main filter. Neither approach eliminates replacement-filter costs.
What this comparison cannot tell you
- No matched-airflow noise or energy test is available here. Rated watts and minimum noise figures cannot establish operating-cost or bedroom-noise winners.
