The Airmega 300 and 400 air purifiers are alike in many ways but very different in others.
In some ways, the Airmega 400 is an advanced version of the 300 because the company kept most of the good features and expanded and added to them.
This,in turn, created a more perfect version of the Airmega 300. Here are some of the main attributes of each of these machines:
- Square foot coverage: 1,256 (300) versus 1,560 (400)
- Sleep mode function: manual (300) versus automatic (400)
ong>Power consumption: 57 watts (300) versus 65 watts (400)
Between these two models of air purifiers, the decibel levels, three-stage filtration system, and air intake are all the same.
Simply put, the 300 and 400 models of the Coway Airmega air purifiers have more similarities than differences, but the differences can be significant to some people.
For instance, the 400 covers about 300 square feet more than the 300 model, but 300 square feet is a lot.
The sleep mode on the 300 is manual and automatic on the 400. That means that the 400 models, can automatically detect when it gets dark and then puts the unit into sleep mode.
Sleep mode reduces the consumption of the machine, so this one feature alone can save you a lot of money on your utility bill.
You should also keep in mind that even though the Airmega 400 is a 66-watt machine, this is because it is a lot more powerful than the Airmega 300 model, which only uses 57 watts. So while the number is bigger, there’s a good reason for it.
Differences Between Coway Airmega 300 Versus 400
One of the biggest differences between the Airmega 300 and Airmega 400 is the square footage they cover, with the 400 covering 1,560 square feet and the 300 covering 1,256 square feet.
The Airmega 400 also has a better air-purification system, which basically means it purifies the air much faster than the Airmega 300.
The numbers look like this – these are the clean air delivery rates for each model:
- For smoke: 285 for Airmega 300 versus 328 for Airmega 400
- For dust: 306 for Airmega 300 versus 328 for Airmega 400
- For pollen: 339 for Airmega 300 versus 400 for Airmega 400
This means that the Airmega 400 is more efficient and will purify the air faster than the Airmega 300.
Other differences include the sleep mode function.
Both units have this function, but it is manual on the 300 model and automatic on the 400 model.
Last but not least, the 300 model is 57 watts while the 400 model is 66 watts.
Nevertheless, they are both energy-efficient and powerful, although the Airmega 400 is a bit more powerful than the Airmega 300.
