Rabbit Air MinusA2 SPA-780N is the enhanced version to SPA-780A with Wi-Fi enabled feature. On first look, you can barely see the differences between the 2 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 customizable panel that is swappable for any designer panel you like e.g. Peanuts Designs featuring Snoopy, Gustav Klimpt, Katsushika Hokusai, or Paul Frank. The front panel is compatible in any of the MinusA2 series air purifier. There is also the 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. Continuing with the back, here you will find a top handle slot for movability and 2 bracket holders for holding. On the whole, build quality is top-notch with no signs of off-gassing from the front cover.

Rabbit Air MinusA2 control

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 your 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 main buttons covered, let’s talk about the sensors and how you can control sensitivity. Rabbit MinusA2 comes with a Light Sensor that 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 set to off. Moving to Air quality indicator, you will find Odor and Particle Sensor working side by side together. The indicator will shift from blue (good), purple (medium), and red (poor) depending on surrounding air contaminants. To adjust the air quality 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 sensitivity, Auto Mode – High sensitivity. Press and hold the Speed + Mode button again for 3 seconds to save the setting.

The 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 step 1 by 1 and upon successful connection, you will see the Wireless Indicator on the air purifier switch from flashing to fix illuminated. Buttons on the air purifier are small but you will unlikely to use it since is probably unreachable when is up high. 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, built-in wall bracket, Particle/ Odor/ Light sensor, multi-spectrum mood light, Child Proof Safety Design that automatically stops operation when the front panel is loosed, remote control, filter life indicator, Energy Star certified and 5 years warranty.

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 consistent 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 wonderfully thanks to the dual particle/ odor sensor. You can also switch to Pollen mode manually or Sleep mode when the room is in pitch black for more than 3 minutes.

CADR figures are less impressive than the airflow but still work well against all types or airborne particles, allergens, 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 us.

^ Rabbit Air MinusA2 SPA-780N filters/ technologies/ lifespan
The most impressive features on Rabbit Air MinusA2 SPA-780N is the 6-stage filtration that pretty much captures any types of airborne contaminants thrown to it. The first stage pre-filter will trap large particles like dust, followed by the medium filter and finally BioGS HEPA filter that focuses on capturing fine particles as small as 0.3 microns. Moving on, select 1 of the 4 customizable filters ranging 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. Finally, you have the Negative Ion Generator that releases negative ions to merge with positive ion airborne particles. The heavier particles will drop from the air and Rabbit Air filter will be able to pick up from there.

Filter maintenance and care

To change Rabbit Air MinusA2 SPA-780N 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 (Pre-filter, Medium filter, HEPA filter, customized filter and Activated Carbon Filter). Open the plastic wrap on the new replacement filter set, insert back all the filters to the filter 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 and the need to take down the air purifier from the wall. The better news is you only need to do it every 1 – 2 years unless you decided to clean the washable pre-filter from any particles blockage. The pre-filter is the only cleanable filter in Rabbit Air MinusA2 SPA-780N that can be clean through light vacuuming with a nozzle or brush.

Rabbit Air MinusA2 SPA-780N 193 cfm dust CADR might not seem very impressive, it is still highly capable in removing airborne dust. As for fine particles like pet dander, dust mites, fungi, pollen, mildew, mold, spores, and germs, you bet one of the 6-stage filtrations will have no problem dealing with it. Against strong chemicals like radon, ammonia, VOCs, tobacco, and cigarette smokes, the default activated carbon filter will do the trick but there is no farm opting for an upgrade.

Using the same brushless direct current motor design, Rabbit Air MinusA2 is quiet at Silent speed (25.6 dBA), audible at Low/ Medium speed and audible at High/ Turbo speed (51.3 dBA). Negative Ion Generator noise is not too bad on everyday use. For night time use, Sleep mode will automatically be activated when all lights are out.

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 in lower energy usage rate.

^ Replacement filters/ estimated cost
Perhaps the most surprising factor, Rabbit Air MinusA2 SPA-780N is only fractioned more expensive than the "A" version. Given the specifiction is exactly the same, this would seem like the better buy but let's not forget, both version also comes with a remote control so the Wi-Fi enabled features might be redundant. Annual filter replacement cost is on the lower side despite having so many extra filters. On average use around 12 hours a day, you can expect the filter kit to last more than 2 years.
Rabbit Air seldom have discounts and this is true across all platform. If you are planning to buy SPA-780N, consider buying straight from Amazon as almost everyone has an account there and has 30 days return policy. Buying from Rabbit Air official website is also doable if you want more front panel design option and direct customer support.

Rabbit Air MinusA2 SPA-780N VS the challengers

Rabbit Air MinusA2 SPA-780A

Rabbit Air MinusA2 SPA-780A

Give up on the WiFi-enabled features, you won't be able to tell the 2 models apart as they share the same design, dimension, airflow delivery rate, CADR, and filtration setup. Price differences are not much either the filter replacement cost is the exact same. Is it worth the downgrade? Only you can decide.
Airmega 400S

Airmega 400S

Much more expensive to own with filter replacement cost at around 2 times more, if you want a better airflow delivery rate, super high CADR, wider purifying coverage, and a much more refine IoCare app, this is it. Filtration wise is the comprehensive 6-stage VS dual pre-filter Max2 filter. Pick your side.

Airmega 300S

Like Airmega 400S, this is the lower spec version with slightly weaker CADR, applicable area, and airflow performance but gain a much lower price and filter maintenance cost. Still more expensive than Rabbit MinusA2 though.
Blueair Classic 605

Blueair 605

The 4-stage filtration might seem inferior to Rabbit Air MinusA2 6-stage filtration, it can actually remove fine particles as small as 0.1 microns. Combining HEPASilent Technology is the 3 times more powerful CADR that promises swift purifying for all three dust, pollen, and smoke. The major drawback is the pricing and filter cost; Far from cheap as with most Blueair machine.

Final thoughts on Rabbit Air MinusA2 SPA-780N

Slightly late to join the party, Rabbit Air MinusA2 WiFi enabled feature is a welcome inclusion in Rabbit Air MinusA2 lineup. 89% of the Amazon reviewers that gave it 4-5 stars like the overall build quality of the air purifier that doesn't feel remotely cheap. People also praised its 6-stage filtration depth particularly in removing cigarette smoke and odor. Others compliment include the bundled remote control, how silent the air purifier is, and low filter replacement cost. Surprisingly very few people complimented the customizable front panel. As for the bad, the very few5% of the users that gave it 1-2 stars are angry the air purifier is incapable of filtering out odor, or they received a bad unit that doesn't work.
