A Deep Dive into the RabbitAir A3 Ultra Quiet Smart Air Purifier
After a little over a week of use, I noticed less dust and fewer odors in my home. This experience has been transformative, especially given my sensitive nose, allergies, and the presence of a toddler who is constantly exploring every corner of our living space.
As someone who is quite particular about air quality, I've tried various models of air purifiers and have always been on the lookout for something that not only performs well but also offers smart features. When I was presented with the opportunity to test the RabbitAir A3 Ultra Quiet smart air purifier, I was eager to see how it would enhance the air quality in the rooms we spend the most time in.
The unboxing experience was impressive, and after a week of dedicated use, I discovered several key features that made this model stand out.
My Favorite Things
- Lighting options and mountable design: The ability to customize the lighting adds a personal touch to the device.
- Customizable specialized filter: This feature allows users to tailor the filtration system to their specific needs.
- Personalizable with a decorative cover: The option to choose a cover that blends with your decor makes the device more aesthetically pleasing.
- Handy child lock: This feature ensures safety for households with young children.
- Convenient app control and monitoring: The app provides an easy way to manage and monitor the air purifier's performance.
Annoyances
- Button inputs are hard to decipher: Some buttons may be confusing without a clear label.
- Some lag between inputs and setting changes in the app: There can be a slight delay when adjusting settings through the app.
Key Features and Findings
I had been looking for a more powerful, smart air purifier for our open concept kitchen and living room, which made the chance to test the Rabbit A3 highly appealing—especially with the specialized odor-removing filter to absorb cooking smells.
After spinning it up, I knew that this model was the perfect one for this combined space.

Setup
While my sample unit came with the personalized Odor Remover layer installed, the filter placement process is one of the easiest I've encountered in a machine with multiple filter layers. The cover is magnetic, which makes for straightforward removal and replacement, and all the filter components snap into place with ease.
I'm a big fan of noticeably informative quick-start guides, and the RabbitAir A3's guide aces that test. The RabbitAir app also walks through each step of the connection and pairing process to remove any guesswork.
The one oddity of setup was having to enter a serial number located on the bottom of the unit, which required awkwardly fumbling to turn the A3 on its side to capture it. Besides that, though, finding my unit, pairing it, and connecting to Wi-Fi was speedy and took minutes.

App and Smart Features
The RabbitAir app interface is clean and straightforward, with clearly labeled controls for adjusting speed, enabling various modes, including around lighting, schedules, timers, and my favorite, child lock. There's also a convenient filter indicator percentage level and a link to purchase a filter refill directly within the app.
I found remote access through the app convenient for my daily needs, but if you use Alexa, the A3 is Alexa-compatible if you prefer to interact with your air purifier that way.
While you can drill down for a quick real-time overview of air quality levels, down to PM 1.0, PM 2.5, and PM 10 levels, there's no historical reporting in the app. However, when I asked about reporting, the company informed me that customers can contact customer service directly to receive long-term data if you're curious about air quality trends in your home.

Noise Levels and Performance
Two of my favorite performance aspects of the A3 include the ability to set the fan speed on manual mode and let the device do its smart thing on auto-mode. These are the configurations I interacted with the most, adjusting fan speed manually when cooking smells lingered or turning the sensitivity up to its highest, level 5, when I wanted the air purifier to work a bit harder.
As the name indicates, this A3 model aims to perform efficiently and quietly, and it really does just that. At its highest fan speed it's still markedly quieter than other models I've tested, which tend to get distractingly loud the higher you crank them up.
Honestly, right when I unboxed and plugged this baby in I observed a huge difference in air quality, specifically odors and what felt like irritants, like dust and general seasonal allergies that had been bothering me.
RabbitAir even reports that lab testing proves this unit is capable of removing up to 99.9 percent of mold spores in 30 minutes. We don't have a mold problem or terrible air quality in our home, but once the A3 got to work against cooking smells, I felt reassured. It was sensing what my human nose was detecting and springing into action as advertised.
In my book, the six levels of filtration, including HEPA and a specialized Odor Removal layer, made a noticeable difference in our home's air quality almost immediately.

Design
Perhaps one of the most unique aspects of the RabbitAir A3 is that its wall-mountable and customizable with a personalized skin. I chose a standard white design, but folks who want to blend this machine into their decor, as a sort of art piece, have numerous options to choose from.
RabbitAir also explains that there's a benefit to placing the unit on the wall or on a higher surface, to increase efficacy, especially when placed near the source of whatever you're hoping to mitigate. In my case, I put this unit on a kitchen counter ledge, which proved far more effective at battling cooking smells than when I originally placed it on the floor.
I also like the mood lighting option and night light feature. The display can also dim completely. If I had to nitpick one design aspect that doesn't quite make sense its the onboard LED interface. The indicators float around in an attractive way, but it's tricky to discern what they mean without referencing the manual. However, like me, I don't think most customers, regardless of whether you're using this in a smart bedroom or kitchen, will be using the machine that way given the convenience of remote app control.

The Bottom Line
The RabbitAir A3 Ultra Quiet Air Purifier is one of the most capable and effective air purifiers I've tested, and I'm a big fan. The convenience of app and voice assistant control, thoughtful touches like a child lock, display preferences, mood lighting, and a magnetic cover all add up to give this machine an elevated look and feel.
And the performance speaks for itself. In the week and a half I used this machine, I noticed a discernible improvement in overall air quality, less allergy irritation and dust and faster dissipation of cooking smells.
My only hesitation is the price point, which might give customers some understandable sticker shock. However, the six-stage filtration system delivers up to 12 months of performance before needing replacements. And you can opt in to a filter replacement program that ships all six filters to your door for under $116, which is on par with other models in the high-end range.
This premium air purifier isn't cheap, but after spending time with this model, I feel confident that the A3 won't disappoint the buyer who's serious about investing in clean indoor air.
