  • Top-notch True HEPA Filter

Rabbit Air is one leader in air purifier industry since 2004. Their fame has risen to a new level since they won “Best air purifier” title given by New York Magazine for their Rabbit Air BioGS 2.0. As the upgrade to the successful BioGS, I have high expectation for the BioGS 2.0. Now, let’s jump in the Rabbir Air BioGS 2.0 Review.

Other Rabbit Air’s Air Purifier Reviews

1, Rabbit Air MinusA2 Review.

Rabbit Air BioGS 2.0 Price

In air purifier market, Rabbit Air always offer the mid-range air purifier devices. Rabbit Air BioGS 2.0 is a top-class air purifier, but not in the same vein as the flagships Rabbit Air MinusA2 or Blueair Classic 605. The air purifier targets at a lower-range segment, but still comes at a $20 to $30 price increase over many potential competitors like Winix WAC9500 or Levoit LV-H133.

Even though Rabbit Air has improved the Rabbit Air BioGS 2.0 with the new MinusA2, it’s still worth taking a look at the Reddot Award winner in 2014 for your next big purchase. The price of this Rabbit Air BioGS 2.0 doesn’t change since launching, and you can keep most of the value when sell it after easily.

Now, the starting price for the Rabbit Air BioGS 2.0 can be found from $369. The package is an enticing one, but staying in a tough mid-range segment requires Rabbit Air BioGS 2.0 to stay ahead. The Honeywell AirGenius 6 HFD360B is finally released, marking a very ambitious move from another popular American brand. And don’t forget the Blueair Classic 205, a rare Smart air purifier that uses the most progressive air filtration technology.

We have recently reviewed the Dyson Pure Cool Tower and Dyson Pure Cool Link Desk in the same price range. These air purifiers, though don’t have the ionizer like our today Rabbit Air BioGS 2.0, are running the best fan power in mid-range segment, overwhelming every other device that you can buy with $399.

Of course, the Rabbit Air BioGS 2.0 is not only a sleek device for looking, but also one of the best air purifiers for the price with a high-quality BioGS HEPA filter.

Rabbit Air BioGS 2.0 Design and Size

Rabbit Air BioGS 2.0 were designed to make people remember why ultra-premium air purifier exist, and to firmly establish Rabbit Air at the top of the market as far as innovation, design and manufacturing are concerned.

For a long time, the design of an air purifier never change. That’s why we can’t stop looking at the new design of Rabbit Air BioGS 2.0. Sure, it is nothing like the previous BioGS 1.0. The design concept of Rabbit Air BioGS 2.0 is “flow”. To emphasize this flow, Rabbit Air makes this air purifier with a curvaceous body. With this new model, Rabbit Air BioGS 2.0 is stylish, unobtrusive and elegant. Thanks to that concept, this air purifier has won multiple of design awards since 2014.

From the front, we will have an user interface with automatic light. All LED indicators have the same white color making the BioGS 2.0 look beautifully minimalist. Not like other air purifiers, Rabbit Air BioGS 2.0 has only one button to adjust everything. This is a key point in the battle of aesthetics versus usability. With only one button, Rabbit Air BioGS 2.0 is really beautiful, but it also increases the chance of this one button be null, or destroyed.

From both sides and the bottom is the air intake grill, hiding in the stylish body of Rabbit Air BioGS 2.0. On top of this air purifier, you will find a big air outlet to exhale the fresh air back to your room. This air purifier is simply gorgeous like that.

Rabbit Air BioGS 2.0 comes with 2 main editions, similar to the predecessor BioGS. The SPA-550A is the smaller one, which can cover only 550 square feet. The SPA-625A has an area coverage of 625 square feet, also features 3 main colors while the SPA-550A model only has a White edition.

In fact, I love the design of Rabbit Air BioGS 2.0 the most in all air purifiers today. It is just beautiful. For the size, this Rabbit Air BioGS 2.0 is not portable with a height of 22 inches, however, it is not big, either. With a weight of only 16.8 lbs, this air purifier can be put easily anywhere in your house. Compare to other air purifiers at the similar price range like Winix WAC9500 or Blueair Classic 205, this air purifier is quite lighter.

Rabbit Air BioGS 2.0 Filters

When it comes to raw performance of an air purifier, we decide based on how many filters it has and the air filter types are used. Though doesn’t have a Six-stage air purification like the latest MinusA2, Rabbit Air BioGS 2.0 is still one of the best air purifiers in the world with its 4-stage air purification:

  1. Pre-filter – The polluted air must pass through a pre-filter, there it will capture all large particles, along with dust mites and some of pet hair. It is washable and permanent.
  2. BioGS HEPA Filter – It is a True HEPA filter that captures 99.97% of down to 0.3 microns allergens, virus particles, pollen, mold and fungi particles. Rabbit Air advances their air filter process, therefore extend both optimal filter efficiency and filter life of their HEPA Filter.
  3. Activated Carbon filter – Made of high-grade granular activated carbon, this Activated Carbon filter will eliminate odors and smokes, also reduce the common household chemicals.
  4. Ion Generator – allows the particles to get trapped more easily by your air purifier’s filters, or to settle onto the floor where they can be picked up by your vacuum instead of accidentally inhaled. Can be switched on/off.

The reason for having a Rabbit Air BioGS 2.0 Air Purifier is because of their BioGS HEPA filter. It is better than normal True HEPA filter (a certified air filter to help capture contaminant particles) thanks to Rabbit Air technology reducing the buildup of common allergens and the growth of bacteria and viruses on the filter. It makes the Rabbit Air BioGS 2.0 HEPA filter last for up to 3 years before replacing a new one.

Also, a combination with an Ion generator is necessary in trapping small airborne pollutants. It will emit a cloud of negatively charged ions to attract the contaminants back to the physical filter. As a result, the performance rating of Rabbit Air BioGS 2.0 is nearly powerful as other high-range air purifiers.

There is a high concern of Rabbit Air air purifiers having ion generators in their structures. Studying said that the ozone emission could irritate asthma and respiratory issues, however, in this Rabbit Air BioGS 2.0, an amount of 0.001 ppm (parts-per-million) was recorded for ozone emission. It is 50 times less than the standard 0.05 ppm for safety, so you shouldn’t worry about it. Anyway, this ion generator can be switched on or off easily.

I have put the Rabbit Air BioGS 2.0 in a test comparison with a $349 Honeywell AirGenius 6 and a Blueair Classic 205, in very same conditions: large coverage of 200 square feet, running continuously in 1 hour. The result, my Rabbit Air BioGS 2.0 had the efficiency of 99.92% of as small as 0.3 microns particles. The Blueair Classic 205 was better with 99.95%, while the Honeywell HFD360B dropped to only 92%.

Also, the price of Rabbit Air BioGS 2.0 HEPA filter replacement is only 2/3 the price of MinusA2, which is a big plus for anyone who consider a budget air purifier. And for a durability of 3 years, a $79 BioGS 2.0 Filter Kit’s annual filter cost is only $26. You should know that the annual filter cost of Blueair Classic 205 is about $90, because its air filter can only last for 6 to 8 months.

Rabbit Air BioGS 2.0 Room Coverage

It is safe to say that Rabbit Air air purifiers are for home use. So the Rabbit Air BioGS 2.0 room coverage is enough for a common household in the United States.  I suggest you to check the ACH (air change per hour) and CADR (cleaning air delivery rate) before purchasing any air purifier.

Rabbit Air BioGS 2.0 has two editions with different room coverage. While the SPA-550A can only cover up to 550 square ft in your room, you had better to use the SPA-625A for a larger room, as it can cover up to 625 square feet. This area is for normal use, but for a serious allergy sufferer, Rabbit Air BioGS 2.0 is better for a room coverage of only 300 square feet.

The ACH of Rabbit Air BioGS 2.0 is the same with MinusA2. It is 2X for normal residential use and up to 4X for allergy sufferer. Note that a 4X ACH translates to an air purifier can clean a room 4 times in a hour, which means this Rabbit Air BioGS 2.0 will clean a room at least once every 15 minutes.

The CADR of Rabbit Air BioGS 2.0 is 165 Dust/ 152 Smoke/ 180 Pollen (cfm), which is for SPA-625A version (the SPA-550A version has lower fan power). CADR rating tells exactly how fast an air purifier can clean the air within a particular size room. With this CADR rating, Rabbit Air BioGS 2.0 is more suitable for a room under 300 square feet than a 600-sq-ft area as it stated in advertisement.

Rabbit Air BioGS 2.0 Sound

For every air purifier, it is important to know if it is quiet or not. The fan technology of Rabbit Air air purifier is really great, if not want to say it is the best fan technology at the moment. Therefore, all of Rabbit Air products produces little to no sound.

Rabbit Air called their fan technology Ultra Quiet, implying that the sound is a key advantage of this brand. Using a cutting edge Brushless Direct Current Motor, Rabbit Air BioGS 2.0 can operate 5 fan speeds with only a noise level of 22.8 decibels (db) at low setting. This noise level is even less than the quiet MinusA2 SPA-780A, and as exactly quiet as the sound of whisper.

Rabbit Air BioGS 2.0 Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, an air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review if this air purifier is good or not. There is a illustration graph to show how efficient this Rabbit Air BioGS 2.0 can be with both lower annual energy cost and annual filter cost.

rabbit air biogs 2.0 review

The power consumption of Rabbit Air BioGS 2.0 is varied from 5 to 29 watts (for SPA-550) and 7 to 39 watts (for SPA-625). This difference from the lowest to highest is due to the speed of fan settings. From these numbers, we can verify that Rabbit Air BioGS 2.0 is worth the Energy Star rate. Within the same price range, the maximum power consumption of Blueair Classic 205 is up to 80 watts.

For an air purifier using 5 fan speeds, normally we will think of very high power consumption at highest setting. However, the Brushless Motor of Rabbit Air BioGS 2.0 can provide greater efficiency with more efficient. I don’t want to go in detail of physics, but without any brushes, the fan can run smoothly without continuous energy loss.

Let’s have a quick math, if you are using Rabbit Air BioGS 2.0 for like 8 hours per day, it would cost you only $10 to $12 per year. I could tell that an investment in Rabbit Air BioGS 2.0 is a smart investment.

Rabbit Air BioGS 2.0 Additional Features

For a high-end air purifier devices, people not only demand the high efficiency of air filters but also the additional features one could give. Because all the Rabbit Air air purifiers are among mid-high range, they all have the most important Smart Sensor. This function can adjust the fan speeds following the reality of your home air quality, therefore save the energy better.

The lack of some buttons see big changes to the way in which Rabbit Air BioGS 2.0 operates. Now the device’s operating system is only controlled pretty much via a single button, making it is harder to make acquaintance with. Most importantly, you can still use the remote control to help you better navigate through the functions of Rabbit Air BioGS 2.0.

Rabbit Air BioGS 2.0 adds an idle mode for conserving energy much better. When you don’t need, this air purifier will automatically dim the light.

Also, you don’t need to remember the date to replace your air filters because Rabbit Air BioGS 2.0 has a LED life indicator to remind you.

If you are looking for a Smart device in this price range, you should opt-in for the Blueair Classic 205, or Winix HR1000.
