Key Features of the RabbitAir MinusA2 Air Purifier

1.  Six Stage Filtration and Deoderization System.

Starting with a Pre-Filter which traps and reduces the larger sized allergens such as dust mites, pet hair and pollen.

Then comes the Medium Filter designed to trap and reduce airborne particles which are larger than 1 micron. So that includes moid and fungi, dander and bacteria.

The next filter is the BioGS HEPA Filter. This filter does away with one of the key problems associated with HEPA filters and that’s the growth of bacteria, mold and virus. The BioGS HEPA filter captures and reduces common allergens, mold spores, bacteria & virus which become trapped on the filter.

Then we have the customizable filter. Choose from a range of filters to meet you personal needs. Options include Germ Defense, Pet Allergy, Odor Remover, and Toxin Absorber. 

The fifth level of defense is the activated carbon charcoal filter. Made of high-grade granular activated carbon, which is much more effective than the thin layer of activated carbon found in many air purifiers. 

Finally, there is the negative ions stage. These negative ions are odorless, tasteless and invisible molecules usually found in open spaces such as mountains and beaches. Research is showing that negative ions help to alleviate depression and boost mental energy, and they latch onto airborne particles, weighing them down. This then means that particles can be trapped more easily by your air purifier’s filters.

From reading the reviews available on the internet, most users of Levoit Core 300 air purifier seem very happy with their purchase. 

Best air filtration system ever!

Noticed a difference in air quality within 2 hours.

Reliable, effective and looks amazing.

Works really well but didn't clear 100% of the cigar smoke.

Alternatives to the RabbitAir MinusA2 Air Purifier

Pure Enrichment Pure ZonePure Zone Air Purifier

Although this product looks very sleek, it uses UV light technology to destroy microorganisms.  While it can help how well the system works, I’ve found that this technology can, in some cases, be harmful to the environment. This still looks a very good option though and is worth considering despite being more expensive.

+ Energy Star Certified
+ HEPA filter
– LED indicator lights are too bright
– Not designed for large spaces

Germ Guardian 4825The Germ Guardian

This air purifier comes very highly rated. In my opinion, however, the product has been let down by its design, which I thought was pretty ugly! The purification specifications of the Germ Guardian are almost exactly that of the Core 300, but this purifier comes in more expensive.

+ 3-step filtration
+ Quiet Operation
– Faint blue UV light keeps shining through
– Doesn’t have many smart features

Four Seasons EnvionEnvion by Boneco – Four Seasons FS200

I also looked at similar products, which also have the capability of heating and cooling. This particular model is also a dehumidifier. The higher cost and larger size of such units were not really suitable for my needs. If you’re looking for a wide range of features, then this might be one to look at.

+ Space saving 4-in-1 design
+ Includes a true HEPA filter
– No remote control
– Comes with just a one year warranty


If you’re looking for high levels of functionality, excellent customer service, and a pretty cool looking system, then the RabbitAir MinusA2 has to be a serious contender. The six-stage purification process is double to that provided in many units and the reviews from happy customers seem to testify to its effectiveness. 

The price is on the high end and if you want the wifi functionality you will need to go for a top-end version. But if clean air is your key focus then we can highly recommend that RabbitAir Minus A2.
