There are so many air purifiers on the market right now though, it can be tough to choose the right one for you. How do you know which is the best? How do you know which one will work best for you personally?

We’ve taken two of the best purifiers on the market at the moment and put them to the test to see which you should be spending your cash on. Will the Rabbit Air BioGS or Coway Airmega 400 come out on top? Read on to find out.

Initial thoughts

Both Rabbit and Coway are fantastic brands, who promise only the best from their products. Whilst most Air Purifiers have a lot in common, it’s the differences that can be the biggest factor in making sure you get the purest air you can.

Let’s take a look at the basics of each product.

First up is the Rabbit Air BioGS. With dimensions of 16.6 x 9.8 x 22.2 inches and a weight of 16.8lbs, the Rabbit is a portable machine that can be placed in most areas of the home easily.

In comparison to this, the Coway has dimensions of 14.8 x 14.8 x 22.8 inches and weighs in at 24.7lbs. Whilst both machines are fairly similar in terms of size, the Coway is the heavier and less portable option, meaning that those with any problems relating to lifting heavier items should take care.

Purifying your space

When choosing your purifier, it’s certainly beneficial to keep your home and the space you want to purify in mind.

The Rabbit can purify up to 550sq feet at a time, and it does so twice an hour, making sure you get the best quality air as often as possible. In comparison though, the Coway can purify an area of up to 1,560sq feet twice an hour, meaning that even though there’s hardly any difference in terms of size, the Coway certainly packs a bigger punch.

Filtered for your health

One of the features that stands out the most when it comes to choosing the right Air Purifier for you has to be its filter usage. The better the filter, the better you air quality will be once the purifier has finished its job.

The Rabbit relies on BioGS HEPA Filtration, which boasts 4 stages of purification as well as deoderization and makes it the perfect choice for your home.

Stage 1 contains the pre-filter, which is both washable and permanent and promises to capture all larger sized particles. Stage 2 is the BioGS HEPA Filter, which traps airborne particles down to 0.3 microns in size and reduces common allergens in the air, supporting and prolonging filter efficiency and life.

Stage 3 is a Charcoal-Based Activated Carbon Filter, perfect for reducing household odors. Finally, stage 4 is the Negative Ion Generator which freshens and fortifies the air produced in your home.

In comparison, the Coway relies on its Max2 filter – a combination of activated carbon as well as a True HEPA filter, which traps and reduces up to 99.97% of particles as small as 0.3 microns from the air.

It also promises to reduce more than 99% of volatile organic compounds and fumes in the air to make your air more sustainable and breathable. The Coway also comes with a washable and permanent pre-filter which helps catch those larger particles efficiently.

Fan speeds

The beauty of these air purifiers are that they don’t disturb your everyday or evening routines due to their clever fan modes.

The Rabbit is equipped with an ultra-quiet BLDC motor, which operates at five different speeds. At its lowest fan speed, its virtually silent, which means a quiet and peaceful environment is always available. At its highest speed, you know that you’re getting the best quality air from your Rabbit purifier.

Similarly, the Coway Airmega also has five fan modes, and at its two lowest speeds, it’s also virtually silent.

Also, with a clever ‘smart’ mode of fan, you can rest assured knowing that this air purifier is adapting to its surroundings and keeping your air as pure as can be. The fan speed will automatically adjust based on the room’s air quality and lighting conditions, helping to improve your air quality without you having to lift a finger.

Special features

Although both purifiers are fantastic, the Coway definitely creeps up on the Rabbit based on its better range of extras.

Unlike the Rabbit Air BioGS, the Coway AirMega is compatible with Amazon’s Alexa’s voice control option, giving you the ultimate ease of use. With voice control options available, it takes the hassle away and gives you more freedom to turn it on wherever you are.

That’s not all though, because the Coway Airmega also includes a pollution sensor, which communicates indoor air quality in real-time. With its brightly colored LED ring, you’ll always be in the know about how clean or dirty your home’s air is, and can manage it accordingly.

Conclusion

Whilst the Coway may be the heavier option, and its filtration system isn’t as advanced, it certainly struck us as being the better of the two devices, due to its larger area capabilities as well as the added extras such as compatibility with Amazon’s Alexa, its pollution sensor, and the ability to self-adjust its fan speed based on the air purity.

For these reasons, the Coway Airmega 400 takes the crown and makes the better choice of air purifier. We think that this air purifier is worth every penny to keep your home fresh and free from nasty allergen particles.

If you have a large space you want to remove irritants from, We recommend the Airmega 400. All of Coway air purifiers do an excellent job of attacking indoor pollutants, and we highly recommend any of them.
The Levoit Vista 200 air purifier has some strong suits, but in our opinion it falls short of carving out a meaningful niche for itself. Its ideal use would be in a small bedroom occupied by someone who is sensitive to noise.
With high end air cleaning performance, the Honeywell HPA300 is the perfect combination of power and finesse. It cleared airborne particulates out of a smokey testing room faster than most air purifiers.
