Levoit Core 600S-P vs Coway Airmega 300: The square-foot labels mislead because the air-change rates differ
Quick verdict
App scheduling, a smaller footprint and a lighter cabinet favor the Core 600S-P. If onboard operation and washable prefilters matter more, choose the Airmega 300. The room labels rest on different air-change rates, so Coway's 628 sq ft figure isn't directly larger than Levoit's 606 sq ft rating.
Before you buy
Why, and what it costs you
Put the room labels on a common basis before comparing
Converted proportionally, Coway's 628 sq ft at 4 ACH comes to roughly 523 sq ft at 4.8 ACH.
Where this comes from
628 × 4 ÷ 4.8 = 523.3 sq ft. The conversion just explains Coway's own room label and is not a new certified room rating.

In practice
Differences you will notice
Put the room labels on a common basis before comparing
Converted proportionally, Coway's 628 sq ft at 4 ACH comes to roughly 523 sq ft at 4.8 ACH.
How we worked this out
628 × 4 ÷ 4.8 = 523.3 sq ft. The conversion just explains Coway's own room label and is not a new certified room rating.
Levoit has the smaller cabinet base
The footprint of its shell is about 18% less.
How we worked this out
12.3² = 151.29 sq in, 13.6² = 184.96 sq in, and (184.96 − 151.29) ÷ 184.96 = 18.2%, before clearance.
A substantial difference shows up in lifting
Core 600S-P weighs 7.7 lb less.
How we worked this out
21.4 − 13.7 = 7.7 lb, which is about 36% of Coway's weight. How comfortable it is to carry still depends on grip and access.
Plug in your numbers
Can either purifier keep up with your room?
This checks hard limits only. Personal preferences are left out of the math.
Levoit Core 600S-P
Works with your numbers391 CFM of verified clean-air delivery works out to about 9.8 air changes per hour in this room. Hitting the 5 ACH target takes 200 CFM.
Coway Airmega 300
Works with your numbers285 CFM of verified clean-air delivery works out to about 7.1 air changes per hour in this room. Hitting the 5 ACH target takes 200 CFM.
This uses each model’s pollutant-specific CADR at top speed and a target of five air changes per hour. Quieter settings clean less air. Raw airflow and one-change coverage claims are never swapped in.

Spec by spec
Where they really differ
| Spec | Levoit Core 600S-P | Coway Airmega 300 | In practice |
|---|---|---|---|
| Published room rating | 606 sq ft at 4.8 ACH | 628 sq ft at 4 ACH | More area at a lower circulation rate is not a straight win. |
| Published CADR basis | 391 CFM generic CADR | 285 smoke, 306 dust, 339 pollen CFM | A generic CADR should not be quietly passed off as a pollutant-specific test. |
| Remote controls | VeSync app and schedules | No Wi-Fi on Airmega 300 | A different model is the connected Coway 300S. |
| Cabinet base | 12.3 × 12.3 in | 13.6 × 13.6 in | Intake clearance is needed for actual placement as well. |
| Weight | 13.7 lb | 21.4 lb | The burden shifts when floors come into it. |
| Filter upkeep | Combined filter with outer prefilter | Two washable prefilters plus two Max2 filters | Main-filter replacement is required for each. |
Trade-offs
What each pick costs you
With Levoit Core 600S-P
- Vertical clearance is needed for the taller 23.6-inch body
With Coway Airmega 300
- Moving a cabinet of 21.4 lb is heavier work
Change of plan
When the answer changes
A connected purifier is required
Go with Levoit Core 600S-P. The Airmega 300 lacks Wi-Fi.
Your main maintenance requirement is washable separate prefilters
Go with Coway Airmega 300. Coway documents that feature.
Decision guide
How to decide
The Core 600S-P is the pick for app scheduling, a smaller footprint and a lighter cabinet. The Airmega 300 is the pick when onboard operation and washable prefilters count more. Different air-change rates sit behind the room labels, so Coway's 628 sq ft figure is not directly larger than Levoit's 606 sq ft rating.
Start by comparing circulation rates
606 at 4.8 ACH and 628 at 4 ACH are different workloads. Converting proportionally makes the distinction visible, though the result shouldn't be presented as a new certification. Real operation is still affected by ceiling height, open doors and the speed you choose.
Choose how you'll control it
Levoit fits changing schedules and remote operation, while the Airmega 300 offers automatic control on the unit, a timer and an Eco mode. Choosing Coway for simplicity is reasonable when remote access would add little.
Factor in upkeep on both sides
Washable prefilters on the Coway can help where large debris builds up, yet its Max2 filters still need replacing. Levoit has the smaller, lighter cabinet. Price the exact filter set instead of assuming a particular filter shape is cheaper over several years.
What this page can’t tell you
- No sound or power testing at matched airflow was performed. The 523 sq ft conversion explains a label and isn't a manufacturer-certified replacement rating.
