If you’re searching for a simple, smart air purifier that’s got all your needs covered, the AIRMEGA 300S Smarter App Enabled Air Purifier could be your best choice. With Coway Airmega’s slogan stating that Clean Air is our Healthy Obsession, you know you’re in good hands with this company’s values. Let’s discover everything they have to offer with this product.
The basics
The 300s weighs in at 21.4lbs, making it a lightweight, portable structure that’ll fit perfectly in any corner of the modern home. Without castor wheels, it may not be as maneuverable as you’d like, but such a lightweight model is so easy to move without them that it’s not a deal breaker.
With dimensions of 13.6 x 13.6 x 21.2 inches, the AIRMEGA 300S isn’t going to be the main event in any room. It won’t stick out awkwardly, and it’s easy to pop in a corner.
That’s not to say it’s not stylish. In fact, AIRMEGA have gone above and beyond to make the 300s the perfect addition to any modern room, and with its sleek and chic colors and LED technology, you may even want to pop it pride of place.
What Features Does the AIRMEGA 300S Smarter App Enabled Air Purifier Have?
This is a hard working air purifier that can comfortably purify the air in any room up to 1,256 sq ft, so it’s perfect for any small or medium sized rooms.

First up is its incredible real time air quality monitoring, which can accurately gauge the air quality in your chosen room and even set its fan speed accordingly to give you better grading within minutes thanks to its uniquely designed Smart Mode function.
At the top of the unit you’ll find its LED ring light, which tells you all you need to know with a simple color grading system. With a red ring light, your air quality is bad and needs instant improvement. Moving up the scale to yellow, this is for poor graded air quality. Green is for good quality air, and highest on the scale you’ll find blue, which means you’ve got the perfect balance.

Is the 300S a Powerful Model?
Yes, thanks to its Dual Suction design, you’ll find that the AIRMEGA 300S works harder and smarter than other models. This air purifier is able to drag your room’s contaminated air through its two side vents, whilst pushing fresh, clean air back into your room through the top of the unit, giving you twice the power for double quick freshness.

Working alongside this power are its two filters. The air is first pushed through the pre-filter, a well-designed filter that’s used to trap the larger contaminants that are pulled into the purifier. This includes hair, fur, or any larger dust particles that are simply too big to be taken care of by the second stage of filtration.
The great thing about the pre-filter is that it’s easily cleaned by simply removing it, wiping it down, and returning it to the unit.
The second filtration system is the Max2 filter. This includes a True HEPA filter, as well as an activated carbon filter which work together to capture and trap 99.97% of those microscopic contaminants whilst trapping odors. This is what gives you that extra clean and fresh atmosphere.
When your filters need replacing there’s no need to worry – you’ll be told by the filter indicator. This lets you know exactly when your filters need cleaning or replacing, and works off of how much air they’ve already processed.

The Main Event: the AIRMEGA 300S Smarter App
What makes the 300S unique is its Smart App. This app can be downloaded onto your smartphone and will give you all the opportunities to keep on top of your air quality no matter where you are.
Get real-time air quality notifications, monitor how much life your filter has left, and even schedule your 300S to work at any given time, whether you’re home or not.
The app can also be combined with Amazon’s Alexa, so you can command it to get to work just with your voice. It’s the perfect combination to give you fresh, clean air on demand.
Conclusion
If you’re looking for an easy unit that can be controlled from anywhere, the AIRMEGA 300S is the perfect addition to your home, especially if you have a demanding schedule that keeps you out of the house all day.
With the AirMega 300S by your side, you’ll feel the benefits as soon as you walk through the door.
