Design And Usability

Rabbit Air MinusA2 SPA-780N weight
19.4 lb (8.8 kg)

Rabbit Air MinusA2 SPA-780N is the enhanced version to SPA-780A with Wi-Fi enabled. On first look, you can barely see the differences between the two as it is the exact same air purifier that we loved. At 21.4 x 20 x 7 in and 19.4 lb in weight, it is rather heavy but rests assured, it is definitely wall-mountable. Upfront you have the same panel that is swappable for any design you like. E.g. Peanuts Designs featuring Snoopy, Gustav Klimpt, Katsushika Hokusai, or Paul Frank. The front panel is also compatible with any of the MinusA2 series air purifier. Staying at the front, there is a 4 color mood light bar that many people confuse it as AQ indicator. Air inlet is located at all sides with only 1 air outlet at the back. At the back, you will find a top handle slot and 2 bracket holders for wall mounting. On the whole, build quality is top-notch with no signs of off-gassing from the front cover.

The front black bar control panel is easily accessible especially if you plan to hang it on a wall. Let’s go through the controls 1 by 1. Power button does what a power button does. Speed button will cycle between the Silent, Low, Medium, High, and Turbo. Short press on the Mode button will cycle between Auto mode or Pollen mode. Press and hold the Mode button will reset the filter replacement indicator.

The Replace Filters Indicator will only illuminate when it is time to change the filters. Mood Light button will either turn on or off the light bar. When the air purifier is in Auto or manual speed mode, the Mood Light bar would be in solid blue color. When is in Pollen mode, the Mood Light bar will cycles from blue – purple – light purple – pink. Ion button will activate/ deactivate the Negative Ion Generator.

Rabbit Air MinusA2 control

With all the main buttons covered, let’s talk about the sensors. The Light Sensor will activate Sleep mode when the room is in complete darkness and more than 3 minutes. In Sleep mode, fan speed is set to silent and all indicator lights are off. Moving to AQ indicator, you will find Odor and Particle Sensor working side by side together. The light will shift from blue (good), purple (medium), and red (poor) based on surrounding air quality.

Like every other Rabbit MinusA2, you can control the sensitivity level. To adjust the AQ sensitivity level, press and hold the Speed + Mode button for three seconds. On success, the Air Quality indicator and Auto Mode indicator light will blink. Continue by pressing the Speed button to choose the sensitivity level. Replace Filters – Low Sensitivity, Pollen Mode – Standard, Auto Mode – High sensitivity. Press and hold the Speed + Mode button again for 3 seconds to save the setting.

A unique feature that is only available in the N version is the WiFi enabled option. To start using the feature, download Rabbit Air App from Apple Store (iOS) or Google Play Store (Android). Follow each steps 1-by-1. Upon successful connection, the Wireless Indicator switch from flashing to fix illuminated. Overall, buttons on the air purifier are small but you will unlikely to use it when you hang it on the wall. Remote control and your smartphone will play a bigger role here.

It’s a long list of features so let’s recap everything again. 6-stage filtration, 5 speed plus Auto/ Pollen/ Sleep mode, remote control. Built-in wall bracket, Particle/ Odor/ Light sensor, multi-spectrum mood light, filter life indicator. Child Proof Safety Design that automatically stops operation when the panel is loosed. Energy Star certified and 5 years warranty.

Filters And Performance

Like the non-WiFi variant, Rabbit Air MinusA2 SPA-780N air purifier uses a 6-stage air cleaning filtration that can remove all types of indoor allergens. The pre-filter blocks dust, hair, lint to prevent large particles from passing through. Against finer particles that manage to sneak through, the medium filter captures them as small as 1 micron. For the finest particles at a microscopic level, you have the HEPA filter that removes 99.97% of allergens as small as 0.3 microns including mold, mildew, pollen, pet dander. For an even more comprehensive filtration, you have the option to choose 1 of the 4 customizable filters ranging from Germ Defense Filter, Pet Allergy Filter, Toxin Absorber Filter, to Odor Remover Filter. The granular activated carbon filter absorbs toxic and odors including cigarettes, VOCs, radon. Lastly, the negative ion generator disperses millions of negative ions that attach to positive ions pollutants in the air. The attached heavier pollutants will eventually fall from the increased weight for Rabbit Air MinusA2 SPA-780N to capture.

Power consumption
7 - 61 W
Rabbit Air MinusA2 SPA-780N is a very powerful and capable air purifier. There are no two ways about it. As a result, the 25.6 - 51.3 dBA noise level is not at the lowest point but that is completely understandable. Despite certified as Energy Star, the 7 - 61 W power consumption is also not at most ideal level especially with the air purifier at full blast. The good thing is Rabbit Air MinusA2 SPA-780N uses only 0.5-watt power during standby, the display screen can be turned off and in real-life situation, the air purifier would not always have to run in maximum speed so Auto mode would come nicely into play.

^ Replacement filters/ estimated cost
Rabbit Air MinusA2 SPA-780N is skyrocketed high to a point that at retail suggested cost, it's almost unreachable to common folks. Filter replacement cost doesn’t look too good either as a new set of filters including Titanium Pro would cost more than 1 brand new top-range air purifier with filters. If pricing is not a thing to be concerned about, you have yourself an elegant, premium Rabbit Air MinusA2 SPA-780N that is extremely capable in filtering out any types airborne contaminant in the room.

Rabbit Air MinusA2 SPA-780N VS The Challengers

Airgle AG800

Airgle AG800

The "cheaper" alternative that provides equivalent design and filtration capacities. The cheaper annual filter cost comes with a weaker filter set without Titanium Pro system.

IQAir HealthPro Plus

The popular premium segment air purifier that offers similar filtration performance yet it's way cheaper and easy to maintain in comparison. No Auto mode is the surprising big miss feature.

  • Easily pair with most smartphones for advanced personalized setting.
  • Dedicated activated carbon filter and Negative Ion Generator.
  • Low annual filter replacement cost despite utilizing many filters.

  • Trio Particle, odor and light sensor with adjustable air quality sensitivity.
  • Sleep mode activates automatically when there is no light source. Fan speed will still auto-adjust according to surrounding air quality.
  • Five-year warranty that fully cover any manufacturer's defects.


  • Over $600 MRSP starting price EXCLUDING any designer front panel or addon filter.
  • There is still some fine-tuning needed on the app UI e.g. limited scheduling, air quality over time.
  • Overall dust, pollen, and smoke CADR are OK but not over the top figures.
  • Heavy for an air purifier designed to be mounted on the wall.
