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.

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.

^ 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.
MinusA2 SPA-780N 193 cfm dust CADR might not seem impressive, it is still capable of removing dust. No issue with finer particles like pet dander, dust mites, pollen, mildew, mold, spores, and germs. You can count your bet on one of the 6-stage filtration. Against the like of Ammonia, VOCs, and cigarette smokes, the default activated carbon filter will do the trick. No farm opting for Toxin Absorber or Odor Remover upgrade for stronger chemicals.

Power consumption
7 - 61 W

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.

^ Replacement filters/ estimated 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.
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 it is very accessible. Free shipping (choice) and 30 days return policy also standard in Amazon. Buying from the official site is also doable if you want more panel design options and direct customer support. Other retailers like BestBuy, Walmart do carry the brand as well so check it out.

Rabbit Air MinusA2 SPA-780N VS the challengers

Rabbit Air MinusA2 SPA-780A

Rabbit Air MinusA2 SPA-780A

Give up on the WiFi-enabled feature, you won't be able to tell the 2 models apart. Everything is identical from the design, dimension, airflow delivery, CADR, and filtration setup. Price differences are not much either and filter replacement cost is 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 coverage, and a 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

Lower spec version with slightly weaker CADR, applicable area, and airflow performance. It gains a much lower price and filter maintenance cost. Still much more expensive than Rabbit MinusA2.
Blueair Classic 605

Blueair 605

On paper, the 4-stage 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 and the 3 times more powerful CADR output. 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

Admittedly late to join the party, MinusA2 WiFi enabled is a welcome inclusion in the lineup. 89% of the Amazon reviewers that gave it 4-5 stars vote. Most of them like the overall build quality of the air purifier that doesn't feel remotely cheap. People also praised its 6-stage filtration depth in removing cigarette smoke and odor. Others compliment include the remote control, silent purifying, 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. They are particularly angry at the poor odor filtration or gotten a lemon unit that doesn't work.
