Rabbit Air MinusA2 Review (SPA-780N): Wi-Fi Ready!

Rabbit Air MinusA2 SPA-780N review

The starters

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.

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.

Airflow, speed, and CADR

With a purifying coverage up to 815 sq. ft. at 2 air charges per hour or 408 sq. ft. at 4 air charges per hour, Rabbit Air MinusA2 will have no problem covering medium to large room size. Across the 5 fan speed, airflow delivery is spread out consistently. At 58 cfm Silent, 80 cfm Low, 122 cfm Medium, 159 cfm High and 218 cfm Turbo. Auto mode is activated by default and works well thanks to the dual particle/ odor sensor. You can also switch to Pollen mode manually or leave it in Sleep mode. CADR figures are unimpressive but still work against airborne particles, smoke, and odor. Dust CADR stands at 193 cfm, Pollen at 200 cfm and smoke at 180 cfm. Only Pollen CADR barely passed the 200 cfm benchmark set by yours truly. Keep in mind that there are other factors that play a bigger role in filtration efficiency.

What’s inside count

^ Rabbit Air MinusA2 SPA-780N filters/ technologies/ lifespan

The most outstanding features on Rabbit Air MinusA2 SPA-780N is the 6-stage filtration. Starting with pre-filter and medium filter that traps large to medium-sized particles. With all the dust/ hair out of the way, BioGS HEPA filter will focus on fine particles as small as 0.3 microns. Moving on, you have the option to select 1 of the 4 customizable filters from specific usage. Choose either from Germ Defense Filter, Pet Allergy Filter, Toxin Absorber Filter, and Odor Remover Filter. Next is Charcoal-Based Activated Carbon filter that removes smokes, gases, and odors. Lastly, the Negative Ion Generator will release - ions to merge with + ion particles. The merged particles will drop from the air due to the heavier weight and the filter will be able to pick up from there.

Filter maintenance and care

To change MinusA2 filters, first remove the front panel by pulling it up from the bottom. A filter case should be right in the air purifier, take it out by pulling it outwards via the side handles. Lay the filter case on the floor and start removing each filters within accordingly. 1. Pre-filter, 2. Medium filter, 3. HEPA filter, 4. customized filter and 5. Activated Carbon Filter. Open the plastic wrap on the new filter set, insert back all the filters to the case one-by-one in reverse order. Reattach the filter case to the air purifier by pushing it inwards. Lastly, close the front panel through the designated latches. The above steps are slightly time-consuming because of the number of filters. You might also need to take down the air purifier from the wall. The better news is you only need to do it once every 1 – 2 years unless you decided to clean the washable pre-filter. The pre-filter is the only cleanable filter through light vacuuming.

Keep it down

Using the same brushless direct current motor design, Rabbit Air MinusA2 is quiet at Silent speed (25.6 dBA). At Low/ Medium and High/ Turbo speed (51.3 dBA), noise is audible but it is still acceptable. Negative Ion Generator noise is neglectable. For night time use, Sleep mode will automatically be activated when is pitch-black for 3 minutes.

With Auto mode activated by default, power consumption is quite low between at a 7-61 Watts. From our experience, the air purifier would rarely go to Turbo mode unless it is necessary. Adding Sleep mode feature in the list, you will have no problem achieving good energy usage rate.

At what cost

Hmm, Rabbit Air MinusA2 SPA-780N is only fraction more expensive than the "A" version. Given the specification is exactly the same, this would seem like the better buy. Let's not forget though, both versions come with a remote so the Wi-Fi enabled might be redundant. Annual filter replacement cost is on the lower side despite having so many extra filters. On average 12 hours a day use, you can expect the filter kit to last more than 2 years.
