One of the most unobtrusive, eye-pleasing air purifier that is also wall-mountable, Rabbit Air MinusA2 SPA-700A is a squarish frame air purifier that stands out in aesthetic and performance. At 21.4 x 20 x 7 in and 19.4 lb size and weight, it’s far from small but the built-in wall bracket is rigid enough to support the air purifier hefty weight. Up front there is the easy to use control and a highly customizable front panel where you could choose some of the most beautiful, well-integrated panel design such as Peanuts Designs (Featuring Snoopy), Gustav Klimpt, Katsushika Hokusai, Nanami Cowdroy, Paul Frank or original designs by Rabbit Air’s creative team. Air Intake is comprehensive around all sides of front panel; air outlet is only at the back top corner. Continue with the back, there is the standard top handle for movability and bracket holder for wall mounting. No remote-control slot this time around as it does not hold any sense since you going to mount Rabbit Air MinusA2. Overall build quality is solid with no signs of air by-pass plus good grade plastic materials that promises zero ozone off-gassing (with negative ion generator off).

The distinctive black control panel up front allows quick access and view; very important as very likely you will mount the ultra quiet air purifier on the wall. Controls and indicator lights are nicely laid out although can be overwhelming at times. You have 1 main power button, 3 smaller, multi-function buttons, 1 light sensor, 11 indicator lights with fan speed taking up 5 slots and Auto mode, Pollen mode, Sleep mode, Ion (Negative Ion Generator), replace filters (red in color) and air quality indicator light taking up the rest. The AQ indicator light will shift from best air quality in color blue, purple, light purple to red (bad).

Rabbit Air MinusA2 control

To start the air purifier, press and hold the power button for 2 seconds and repeat to turn it off. To change the fan speed, click on the speed button and you change between the 5 fan speeds from silent, low, medium, high, turbo in exact order. Mood light button also has a dual function that will turn on or off the mood light with simple click, press and hold for 3 seconds would activate or deactivate the negative ion generator (ionizer). A bonus function that is hidden in the manual, there is the option to adjust the sensitivity level of the air quality sensors by pressing both the speed and mode buttons for three seconds. Upon doing that, the air quality indicator and auto mode will start blinking and you can click on the speed button to change the sensitivity level. If you see the replace filters indicator is lit, sensitivity level is at low, pollen indicator lid means standard sensitivity and auto indicator lid means high sensitivity. Press and hold the speed and mode buttons again to save the desired sensitivity level. If no action taken with 10 seconds, the air purifier will restore back the sensor’s sensitivity level to the last saved setting. Finally, all the above-mentioned functions are also accessible via Rabbit Air’s remote control.

Lastly let’s wrap-up on the specification starting with the prominent 6-stage filtration, 5 speed with Auto mode, Particle/ Odor/ Light sensor that automatically switch into sleep mode when the room is dark and resumes to a more active mode when light levels increase, Optional LED mood light that can be turned on to produce a spectrum of colors, Child Proof Safety Design that automatically stops the air purifier from operation when the front panel is loosed or removed, remote control, wall-bracket, filter life indicator, Energy Star certified and 5 years warranty.

Airflow, Coverage, And CADR

Rabbit Air MinusA2 SPA-700A has a very decent 700 sq. ft. purifying coverage at 2 air charges per hour. Coverage drop to half (350 sq. ft.) at 4 air charge per hour. Theoretically, the air purifier would cover all sort of room size unless you are staying in a mansion. Airflow is more than sufficient to support its many filters particularly at lower speed starting at 47 cfm, 64 cfm speed 2, 97 cfm speed 3, 140 cfm speed 4 and 187 cfm speed 5 (Turbo). Expect consistent airflow circulation however, it is not the punchiest at speed 5 for its segment that we would put it under “average” comparatively. The default Auto mode (solid blue in Auto) changes the speed fast and accurate thanks to the multiple built-in sensors. There is also Pollen mode that mood light will shift blue >purple > light purple > pink and finally Sleep mode that disabled mood light and air quality indicator but retains the automatic fan speed adjustment. Sleep mode also activates when the room is dark for 3 minutes.

On the other hand, CADR is closer to competitor figures even though it still falls slightly short. Dust free is rated at 173 cfm, Pollen is rated at 171 cfm and Smoke free is rated at 166 cfm. The airflow volume is great against larger household pollutants to micron size particles. Smoke clean air output is also effective against smoke and gases pollutants (with the right type of customized filter).

Filters And Performance

Triumphing most competitors offering with the comprehensive 6-stage filtration and 360 side/ bottom air inlet, perhaps the most impressive features in Rabbit Air MinusA2 are the quality of the filters. First, there is the mandatory washable pre-filter that capture large, visible particles. Follow by second stage medium filter that traps smaller airborne particles down to 1 micron in size. Thirdly, the ever important HEPA filter is excellent in eliminating airborne microorganisms and allergens as tiny as 0.3 microns size at 99.97% efficiency rate. Unique in Rabbit Air is the fourth stage customizable filter where you could choose from 1 of the 4 filters designed to trap specific type of allergens, bacteria or viruses. As such, you have the Germ Defense Filter (effective against germs), Pet Allergy Filter (effective against pet allergens), Toxin Absorber Filter (effective against chemicals) and Odor Remover Filter (effective against smoke and odors). Fifth stage belongs to High-grade granular AC filter that traps smoke, chemicals, and common household odors. Finally, a negative ion generator that finishes up any uncaptured particles by releasing invisible negative ions. The ions would latch onto airborne particles thus weighing them down and enabling the air purifier filters to capture.

Filter maintenance and care

Changing Rabbit Air MinusA2 SPA-700A filters is slightly time-consuming and troublesome due to the 5 filters plus the need to take the air purifier down from the wall. The good thing is you don’t have to do it very frequently as most filters can last up to 2 years. To start with the filter change, first remove the front panel by lifting up from the bottom, continue by removing the filter case by grasping on the 2 side handles to pull forward. Lay the filter case flat and start removing the Pre-filter by pulling its tabs, follow by the Medium filter, HEPA filter, customized filter, and Activated Carbon Filter. With all filters out of the way, prepare the new filter set by removing the plastic package, then insert each filter back to the filter case in reverse order. Once all filters are securely attached to the case, slide the filter case back from the bottom and push it down. Reattached back the front panel via the top latch. There is no need to clean the filters other than the washable pre-filter. Clear off the pre-filter dust particles via light vacuuming attached with nozzle or brush. For stubborn particles, soak and gently wash the pre-filter with warm water between 2-3 minutes before rinsing it out for drying.

^ Replacement filters/ estimated cost
Depends on how you look at it, the hefty price might not give you the best value if, and if your sole requirement is to squeeze out the best possible airflow performance and coverage. What Rabbit Air MinusA2 does give is the unique yet highly functional design along with many practical, convenience features, and most importantly an awesome 6-stage filtration. Another great selling point is annual filter replacement cost is cheap for the bundled filters you would get on an average of 12 hours daily use. Beside Rabbit Air own MinusA2 series, no other air purifiers currently in the market can top that.
If price factor is your main concern, Rabbit Air MinusA2 SPA-700A win hands down as is one of the cheapest and only 6-stage filtration air purifier. Same story with the very low annual filter maintenance cost beating the likes of Winix HR1000, Honeywell HPA300, Alen BreatheSmart, and Airmega models. As for buying the HEPA machine, its selling price is pretty much fixed across all website with no discount or on-going promotion at the time of this writing. Amazon is our top pick as it comes with fast shipping, 30-day return policy and refurbish model (not recommend. Go for brand-new). As for official channel, you get an additional 90-day money back guarantee and the highest varieties of front panel design to choose from at a premium cost. Best Buy, Walmart, Home Depot also carry this model if you want to physically see the air purifier.

Rabbit Air MinusA2 SPA-700A VS The Challengers

[cha1] Same series but higher end with slightly better purifying coverage, airflow and CADR. Rabbit Air MinusA2 SPA-780A offers the same usage experience where you can swap between the front panel design. Filter maintenance cost is the same, but price is higher at an estimated $50 more.
[cha2] Same purifying coverage but with a better dust, pollen and smoke CADR, Alen BreatheSmart Flex is the cheaper alternative that offer the same customizable front panel pleasure. What it does lack is the premium features like Auto mode, air quality indicator, remote control, mood lighting and of course 6-stage filtration available in MinusA2.
[cha3] The higher trim to BreatheSmart Flex, Alen BreatheSmart is a better alternative in terms of CADR and purifying coverage. It also comes with a changeable front panel with plenty of design to choose from. The downside on choosing BreatheSmart is the higher price tag and is technically a 3-stage air purifier and carbon filter is an additional addon option.[cha4] While not exactly light to light comparison, Blueair 605 is clearly the more powerful air purifier with CADR that can go 3 times higher than MinusA2! The HEPASilent Technology is also well-known to deal with the strongest airborne allergens and odors. Adding Wi-Fi support for remote access via phone, the price point and bulkiness could be the only 2 deal breakers.

Final Thoughts On Rabbit Air MinusA2 SPA-700A

It’s amazing how Rabbit Air MinusA2 SPA-700A air purifier manage to fit 5 filters plus a brushless direct current motor into its thin body. Based on Amazon reviews, 89% of the users that gave 4 – 5 stars concurred on Rabbit Air MinusA2 filtration depth against pet allergies and odors. Some users also compliment on the well-built quality, eye-pleasing exterior, energy-efficient, and bundle set of features. A small section of people like the excellent customer support and airflow performance. The only 5% of users that gave 1 -2 stars disagreed on the filtration performance particularly against lingering odors. With the pros clearly outrank the cons, we reckon this quiet HEPA air purifier will do well in the market barring from its expensive price tag.
