There are not many wall-mounted air purifier, let alone a good one. Rabbit Air MinusA2 SPA-780A is not only that, it surpasses most traditional wall-mountable air purifier by offering an incomparable airflow filtration and performance. Unfortunately, that also resulted extra bulkiness and weight of the air purifier despite smaller than most console air purifiers. Fitting is tight with top grade materials used; Expect zero ozone emission or air by-pass from the air purifier. Upfront you have the customizable panel with plenty of design to go for from Peanuts Designs featuring Snoopy, Gustav Klimpt, Katsushika Hokusai, Paul Frank or original designs by Rabbit Air. Right at the middle there is a 4 spectrum color mood light bar which many people confuse it as air quality indicator (AQ indicator is the small dot located at the right panel). Air Intake is excellent at all sides of front panel while there is only one air outlet behind. Nothing much else at the back other than the top handle for easy MinusA2 carrying and 2 bracket holders. Like Minus A2 SPA-700A, there is no remote-control slot because of the likelihood of Rabbit Air MinusA2 SPA-780A been mounted to the wall.

Control panel is also located at front for easy viewing and accessibility especially if you hang it up high on the wall. Rather than using a digital display to show multiple information, Rabbit Air MinusA2 SPA-780A stuck with traditional indicator lights for every single speed and mode the air purifier is in. You have 5 individual greenish indicator lights for the fan speed, 1 for Auto mode, 1 for Pollen mode, 1 for Sleep mode, 1 for Ion to indicates the Negative Ion Generator is in operation, 1 red indicator light for replace filters and 1 air quality indicator light that shift colors between blue (best), purple, light purple, red (worst). Among all that is the main power button and the 3 partially hidden small buttons that thankfully is also accessible through the remote. Speaking of remote, Rabbit Air MinusA2 SPA-780A is one of the few air purifiers with complete controls in their remote. You can control the power, speed, mode and mood light through the dedicated buttons.

Rabbit Air MinusA2 control

To turn on Rabbit Air MinusA2 SPA-780A air purifier, press and hold the power button for 2 seconds and repeat again to turn it off. A simple click on the speed button would change between the 5 fan speeds (silent, low, medium, high, turbo) in the following order. Clicking on the mode button would change between Auto and Pollen mode. Press and hold the mode button for 3 seconds would reset the replace filters indicator. Do note that Rabbit Air MinusA2 SPA-780A will always start with the previous mode of operation it was last in Like mode button, mood light button is also a dual function button that when clicked, it will turn on or off the mood light. Press and hold the button for 3 seconds would turn on or off the negative ion generator (ionizer). Last important info that most people are unaware, you can adjust the sensitivity level of the sensors by pressing speed and mode buttons for three seconds. The air quality indicator and auto mode will start blinking, press the speed button to change the sensitivity level. On your right if you see the replace filters indicator is light up, sensitivity level is low, pollen indicator lights up means standard sensitivity while auto indicator light means high sensitivity. Press and hold the speed and mode buttons again to save the sensitivity level. Failing to do so within 10 seconds and the air purifier will restore back the sensitivity level to the last saved setting.

Wrapping up the spec, Rabbit Air MinusA2 SPA-780A comes standard with 6-stage filtration, 5 speed plus Auto mode, built-in wall bracket, Particle/ Odor/ Light sensor (automatically switch into sleep mode when the room is dark and resumes back when light return), multi spectrum color mood light, Child Proof Safety Design that automatically stops operation when the front panel is loosed or removed, remote control, filter life indicator, Energy Star certified and 5 years warranty.

Rabbit Air MinusA2 SPA-780A is the better version to SPA-700A which bumps up on purifying coverage to 815 sq. ft. (115 sq.ft. more). For asthmatic person that would need a more frequent airflow, expect 408 sq. ft. of purifying coverage at 4 air charges per hour. The wide air purifying coverage allows Rabbit Air MinusA2 SPA-780A air purifier to support small to large room size including bedroom and living hall. Airflow wise it also push up slightly to 31 cfm more starting from 58 cfm speed 1, 80 cfm speed 2, 122 cfm speed 3, 159 cfm speed 4 and 218 cfm speed 5. Overall airflow is also consistent and punchy particularly at lower speed, at higher speed (fourth or fifth speed) there is reasonable enough of airflow to push through the multi-level 6-stage filtration. Auto mode is also available by default with accurate and swift changes thanks to the dual particle/ odor sensor. There is also Pollen mode where mood light will shift blue >purple > light purple > pink rather than solid blue in Auto mode and lastly Sleep mode that works like Auto mode except mood light and air quality indicator will be off. Sleep mode activates when the room is dark for 3 minutes.
Ignoring the typical top charter in the list, Rabbit Air MinusA2 SPA-780A purifying coverage is very impressive overclimbing Blueair Classic 605 and Oransi Max HEPA air purifier. This is also the only air purifier in the category with 6-stage filtration and is wall-mountable. What is standard though like most air purifier in this category, the inclusion of HEPA filter, carbon filter and Negative Ion Generator that will play a major role in the purification journey. So, if purifying coverage and airflow delivery rate is your priority, Rabbit Air MinusA2 SPA-780A would be a safe bet.

As Rabbit Air MinusA2 SPA-780A CADR figures is quite close to each other, is fair to say the air purifier is effective against all types or airborne particles, allergens and smoke (best paired with Toxin Absorber, Pet Allergy or Odor Remover customized filter). The clean air delivery rate is also identical to SPA-700A with Dust at 193 cfm, Pollen at 200 cfm and smoke at 180 cfm. Didn’t break the 200 cfm benchmark but still an impressive figure considering what its competitor model is pumping out.
Compare with other high purifying coverage air purifiers from the likes of Blueair, IQAir, Honeywell, Rabbit Air MinusA2 SPA-780A has the poorest CADR return for all 3 dust, pollen and smoke. The chart above might not fully reflect on Rabbit Air MinusA2 SPA-780A filtration strength as the airflow delivery rate is on par with its wide purifying coverage. This means there is enough airflow to push the airborne particles and smoke to the comprehensive 6-stage filtration. Still, if CADR is critical to your buying decision, you can take a look at the listed air purifiers via the comparison table above.

Same as SPA-700A, Rabbit Air MinusA2 SPA-780A is powered by the 6-stage filtration, high-quality filters that capture airborne contaminants every step of the way. How Rabbit Air MinusA2 SPA-780A works is when the airborne particles flow into the surrounding air inlet, the spinning motor will attract airflow and absorb particles to the pre-filter, smaller particles that manage to by-pass will have to go through medium filter and finally BioGS HEPA filter in the same exact order. This would eliminate most dust, pet dander and allergens as small as 0.3 microns. On leftover smoke, odors and bacteria, you have the option to choose 1 of the 4 customizable filter ranging from Germ Defense Filter (effective against bacteria and viruses such as mold, spores), Pet Allergy Filter (effective against pet dander and pet allergens), Toxin Absorber Filter (effective against chemicals, VOCs) and Odor Remover Filter (effective against cigarettes, cigars, pet or cooking odors). Continue with the step is a Charcoal-Based Activated Carbon filter that dedicatedly trap persistent gases and odors. Ending the filtration process is Negative Ion Generator/ Ionizer that release negative ions to merge with positive ion airborne particles thus weighing them down for the filter to capture.

Filter maintenance and care

To change Rabbit Air MinusA2 SPA-780A 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-780A that can be clean through light vacuuming with a nozzle or brush.

With the new brushless direct current motor design, Rabbit Air MinusA2 SPA-780A Ultra Quiet Air Purifier is virtually silent at low speed (25.6 dBA), slightly audible at second speed and audible but not over the edge at third speed and audible at fourth/ fifth speed (51.3 dBA). Negative Ion Generator noise is reasonable for an ionizer. Great for day or night use where you could easily set the ideal speed noise you are comfortable in or leave it in Sleep mode with lights out.

Energy Star qualified, Rabbit Air MinusA2 SPA-780A power consumption too is at lower tier starting at a mere 7 W consumption rate. While at max speed power consumption rate is higher than the lower spec Minus A2 SPA-700A (61 W vs 47 W), you can still run Rabbit Air MinusA2 SPA-780A 24x7 in the background (best pair with Auto mode) without feeling a pinch on the electricity bill.

^ Rabbit Air MinusA2 SPA-780A replacement filters estimated cost
As the upper version model, Rabbit Air MinusA2 SPA-780A price also increased to equal the added airflow distribution performance while features wise remain the same with SPA-700A. Is it worth the extra cost? That would depend on your needs but personally either of the MinusA2 Ultra Quiet air purifier would do a bang up job when it’s required. On the other hand, Rabbit Air MinusA2 SPA-780A’s annual filter replacement cost is very low despite being a 6-stage filtration air purifier with extra filters. At 12 hours of daily use, the filters could last up to 2 years which should outlast competitor models filter like Winix, Honeywell. Best of all, both version of MinusA2 air purifiers utilize the same replacement filter kit so the extra bucks is a one-time cost.
As you can see from both chart above, Rabbit Air MinusA2 SPA-780A is one of the least expensive air purifier with an exceptional purifying coverage. What’s more impressing is annual filter replacement cost is also the lowest in its segment apart from Rabbit Air BioGS. Like every other Rabbit Air purifiers sold online, there is no differences in selling price so you can virtually buy Rabbit Air MinusA2 SPA-780A at any channel. We highly recommend Amazon not only because it is our bread and butter, Amazon offer free shipping (on selected seller) and a guarantee 30-day return policy. No discount from official website other than the added benefit of 90-day money back guarantee, direct customer support and best stock availability for all front panel design.

The challengers

Rabbit Air MinusA2 SPA-700A

Rabbit Air MinusA2 SPA-700A

The Cheaper and identical version with minimal compromisation on purifying coverage and airflow performance. Rabbit Air MinusA2 SPA-700A 700 sq. ft. coverage by no means is poor, is just a lower specification model that would save you around $50 bucks on the selling price. Filter replacement cost remains the same.

Alen BreatheSmart FLEX

For the much lower price, Alen BreatheSmart Flex is also a good alternative that comes with better CADR, customizable front panel and 4 optional filters to choose from. Downside is the weaker filtration, slightly smaller purifying applicable area, less aesthetic feature and of course it is not wall-mountable.

Alen BreatheSmart Classic

The closest rival in our book, for the same price you’ll get a better coverage, better airflow with higher CADR output air purifier. Alen BreatheSmart matches Rabbit Air MinusA2 in every other way except for its body framework, filtration depth (4 VS 6) and filter maintenance cost that we have to include the addon filters.
Blueair Classic 605

Blueair 605

Despite a mere “4-stage filtration”, Blueair 605 filtration depth is nothing to scoff at as the HEPASilent Technology is one of the best in the industry. Purifying coverage is identical but CADR can go up to 640 cfm for pollen; 3 times higher than MinusA2 SPA-780A. Pricing wise is expensive and so is the annual filter replacement cost although you do get WiFi app support as standard.

In conclusion......

  • 6-stage filtration with improved airflow performance and coverage.
  • Low filter replacement cost despite many added filters.
  • Beautiful, square design with mood light color bar.
  • Wall-mountable with many customized front panel design to choose from (optional purchase).
  • Effective First line filtration (Pre-filter, Medium and HEPA filter).
  • 4 Customizable filter option, AC carbon filter and Negative Ion Generator (Ionizer) for extra filtration.
  • 5 fanspeed with Auto/ Pollen/ Sleep mode.
  • Separate Particle, odor and light sensor. Particle/ air quality sensors sensitivity can be adjusted.
  • Sensitive Sleep mode that activates and adjust the air purifier speed accurately and automatically when light is out.
  • Five-year warranty with free return.
  • All the added features helped push the price up to premium category.
  • For the price you paid, there are better alternate options in purifying coverage, CADR and airflow delivery rate.
  • Far from light despite being a wall-mountable unit with back wall-bracket.
