Rabbit Air BioGS 2.0 Air Purifier Review

This Rabbit Air BioGS 2.0 Air Purifier Review was updated on the 27th May 2020.

Rabbit Air BioGS 2.0 - air purifier

I originally decided to write our Rabbit Air BioGS 2.0 Ultra Quiet HEPA Air Purifier Review due to its impressive 4-stage filtration system with a patented BioGS HEPA filter, which is supposed to last for over 1.5 years.

I also enjoyed the special design of the air purifier, which is unlike anything I’ve ever seen. In fact, this air purifier holds several design awards for it’s great looks. Something Rabbit must be getting used to, as their previous acclaimed model, the air minus has won several awards too.

Even though this unit doesn’t seem to be packed with smart options, it’s energy efficient and quiet, which speaks highly of its capabilities. The price tag of this air purifier is far from being moderate, so let’s see if the unit is truly worth it.

In 2020, we decided to revisit this review, to see if this relatively uncommon air purifier is still as good as we originally thought it was. Or have other newer models overtaken it with their updated tech?

Filtration System

While there isn’t anything special about this filtration system, I wanted to look into the longevity of filters, which the manufacturer claims to be 18 to 36 months.

Pre-filter – A washable permanent pre-filter is well designed to capture large particles before the air passes along to the HEPA and carbon filters. This particular filter does an excellent job of dealing with dust. If you look closely, due to it’s unique design, you can actually see how the dust particles and pet hair are sucked into the unit.

BioGS HEPA filter – The specially designed HEPA filter catches 99.97% of contaminants 0.3 microns in size. It deals with pollen, dander, mold spores, bacteria, and dust mites. The manufacturer claims that this air filter is especially good at killing mold and can serve for at least 18 months, providing you use the air purifier 24 hours per day. I would recommend replacing the filter at least once a year just to be on the safe side. Keeping the same filter for years, no matter how great it is, can reduce the air quality. The replacement filter combination includes HEPA and carbon filter and costs about $80.

Charcoal – Based Activated Carbon Filter – This high-grade filter deals with kitchen and household odors, VOCs, greenhouse gases, exhaust fumes, and smoke. It’s powerful enough to deal with cooking odors in a large kitchen or cigarette smoke inside the house. The replacement story is the same as with the HEPA filter. The combintation price is $80.

Negative Ion GeneratorAn ionizer keeps the air fresh and clean. Thankfully, the generator on this model doesn’t produce any ozone or make noises. You can turn it on and off any time you wish.

Overall, the Rabbit BioGS has a powerful filtration system, which deals with the majority of air contaminants in an excellent manner. However, the replacement filters are quite expensive. If you don’t use the air purifier 24/7, you may extend the filters’ lives to 1.5 years. Then the annual maintenance will cost you about $50.


Rabbit Air BioGS 2.0 - design

The design of this air purifier gets the highest scores. And not just from me. It holds numerous design awards, such as the Germany Red Dot award, Good Design Award by Chicago Athenaeum, Japan Good Design Award (G-Mark), and more.

The design is truly impressive. It looks wonderful in any room regardless of the furniture style. The small downside of this unit is its weight. At about 17 pounds, it’s hard to move around the house. The dimensions are pretty formidable as well. 16.6 x 22.2 x 9.8 inches are hard to fit in a small room. However, the purifier is designed for larger areas, so this shouldn’t be a problem.

The unit has a straightforward control panel on top. The only downside I found is the light, which can’t be dimmed. The purifier doesn’t have a night mode, so light sleepers may have problems with the brightness.

Overall, it’s an excellently designed unit for large rooms. The lack of caster wheels makes it hard to move it around. Thankfully, it’s equipped with a carrying handle.

Smart Options and Sensors

I appreciated the number of smart options this air purifier offers. Even though it’s not Wi-Fi enabled like many new air purifiers, it has a minimal set of features to make a user comfortable.

Filter Life Indicator – You don’t have to worry about timing the filter’s life cycle. The air purifier does it for you. It will tell you how many months you have left before the filter replacement time. The indicator location changes every 3 months.

Air Quality Sensor – In my opinion, this is the most important smart option for an air purifier. It determines the air quality and shows the results on the display. Depending on the mode you choose, you can adjust the fan settings yourself or allow the unit to do it.

Auto Mode – This mode uses the air quality sensor to determine which fan setting to activate. It’s an excellent energy-saving option, which allows you to not have to worry about the air quality and how much electricity you’re using to purify it.

Remote Control – The unit comes with a simple remote control which helps you operate it without getting off the couch.

Timer – The timer allows you to turn the unit off in 4,8 or 12 hours. It’s another energy-saving option.

Overall, I’m satisfied with the number of smart options for this purifier. The only thing I’m not happy about is the lack of a night mode. I can set the fan to the lowest setting to reduce the noise, but there is no way to dim the lights.

Noise Levels

This air purifier is truly quiet. It’s a great choice for light sleepers or people annoyed with fan sounds.

  • Speed 1 – 22.8 dB
  • Speed 2 – 28.6 dB
  • Speed 3 – 33.5 dB
  • Speed 4 – 44.3 dB
  • Speed 5 – 48.6 dB

The noise at the lowest setting is similar to the quiet rustling leaves sound. The highest setting is comparable to the sound of a quiet conversation. You can easily use the first two speeds in the bedroom.

I appreciate the combination of a quiet fan and a powerful filtration system. Even though the unit is large, the manufacturer did an excellent job keeping the fan quiet at different speeds.

Coverage Area

The manufacturer claims that the coverage area of this air purifier is 550 square feet. Let’s check out the CADR ratings.

  • Smoke – 135
  • Dust – 149
  • Pollen – 162

By doing a simple calculation (CADR x 1.5), we find out that this air purifier is suitable for rooms between 202 and 243 square feet. That’s less than half of what the manufacturer claims. I’ve read several negative reviews about this air purifier for this reason. People buying the Rabbit Air BioGS who have large rooms be warned. It’s not built to cycle the air as often as the manufacturer would like you to believe. For a better choice of air purifiers that can handle larger rooms, check out our post on that.

However, if you follow my recommendations and don’t use it in rooms larger than about 245 square feet, you can get excellent results.



This unit has an impressive 5-year warranty. The manufacturer also offers a lifetime technical support. According to the numerous reviews I’ve read about the unit, the Rabbit Air customer service does an excellent job of supporting the air purifier users. The English-speaking branch is located in California and offers 24/7 support.

In order to take advantage of the warranty, you need to go through online registration.

Rabbit Air BioGS 2.0 Air Purifier Review Conclusion

2020 Update: This little rabbit is still a above par air purifier for the money. It gets fantastic reviews on Amazon from users now too. When we first looked at this model, it had only just come out, so user reviews were hard to find at that time. Thankfully now, we feel justified in giving it a good score, as it seems to be very well appreciated by getting a 4.5 rating from over 600 independent user scores on Amazon.

It’s an excellent air purifier with a powerful filtration system and a good set of smart options. If used according to the CADR rating rather than the manufacturer’s coverage area claims, you can get high-quality air purification results.

Top-notch HEPA filter coupled carbon filter and an ionizer keep the air fresh and contaminant free. The air purifier is suitable for bedrooms, living rooms, and basements. It also does a good job dealing with kitchen odors.

The unit is quiet, energy efficient, and well designed. I would recommend it to anyone looking for a powerful air purifier with numerous features.

So there we have it. This little Rabbit is a pretty good air purifier. I think you’ll agree it does look fantastic, and for my money – one of the best looking in the market right now.

The only major downside is that, like many manufacturers these days, Rabbit have decided to vastly overstate the room size it will work well in. If you are looking for an air purifier for a large room, I suggest you look elsewhere. But for moderate to large rooms, it will do a very good job.
