Rabbit Air MinusA2 Price

Rabbit Air is not a brand for cheap air purifiers. Their products are all made of the highest quality material to bring a real deal to air filtration. Moreover, Rabbit Air devices are always lookers. They’ve not just been functional and durable, but also fashionable and delicate.

Other than the older Rabbit Air BioGS 2.0, the Rabbit Air MinusA2 is Rabbit Air’s most advanced big air purifier thanks to its unique and oversized design, with no identical look to the predecessors. It’s also Rabbit Air’s best air purifier. In fact, more than a year after launch it remains at the top of our best air purifiers list.

It is enough said to understand why Rabbit Air MinusA2 will start at $549 for the SPA-700A and can go as high as $619 for the SPA-780N. Its price is $149 more expensive than the BioGS 2.0 at launch, push Rabbit Air MinusA2 directly to the luxury mid-range level. For the same price, you can get other Smart devices like Medify MA-112, Blueair Classic 405 and Blueair Classic 480i, or top up more money for the high-range like Molekule Air or Austin Air Allergy Machine.

We also notice the presence of the latest series in Dyson Pure Cool Tower and Dyson Pure Cool Link Desk – Dyson TP04 and Dyson DP04 within the same price range. These air purifiers, besides the True HEPA filter, are having an amazing cooling fan power to help you survive the summer time. The Dyson Pure Hot+Cool, with a little bit higher cost, will come with the heating power as well.

There is no change in the price since its launching, which encourage anyone to buy this Rabbit Air MinusA2 without the fear of value drop. The highest price point of this air purifier can even match the high-range level.

Rabbit Air MinusA2 Design and Size

Rabbit Air MinusA2 has 3 main editions. The SPA-700A is the smallest one, with a smaller room coverage of 700 square feet. The SPA-780A and the SPA-780N both have the same area coverage of 815 square feet, but the latter also has Wi-Fi function.

There are two standard color editions of Black and White for SPA-780A/N models. You can only have the white edition for the smaller SPA-700A. Below is the White version of Rabbit Air MinusA2 SPA-780A model.

Visually, Rabbit Air MinusA2 is nothing like any other Rabbit Air air purifiers, in term of design or how you interact with it everyday. It comes with a square shape, and is mainly made out of metal with good build. On the front of Rabbit Air MinusA2, we have one LED panel at the center to show if it is turned on or off. On the right side are the function buttons. My only slight annoyance is that the button is quite hard to push down.

The air intake of this air purifier is around the front panel. Basically, the design of Rabbit Air MinusA2 increases the amount of polluted air it can inhale, and maximize the efficiency of the fan power. You will find the air outlet from the top of this air purifier.

To make their Rabbit Air MinusA2 unique, Rabbit Air offers variable of artist series, from Claude Monet, Van Gogh to Hello Kitty Special Edition. It is nice to have one picture art in your home, right?

Rabbit Air MinusA2 could be the slimmest air purifier, with only 7 inches in depth. Though the size of Rabbit Air MinusA2 is somehow broad with 19 inches in height and 21.4 inches in width, you can easily mount it to the wall, and therefore save some precious spaces for your home. To compare with other air purifier brands like Blueair, Whirlpool or Honeywell, I prefer the design of Rabbit Air MinusA2. It is simple, but elegant.

Whenever you have a change of mind to move your Rabbit Air MinusA2 to another room, this air purifier is just 19.4 lbs in weight. With the advantage of being mountable, it is safe to say Rabbit Air MinusA2 is the best air purifier to pick for any kinds of room.

Rabbit Air MinusA2 Filters

The most important criteria to decide one air purifier’s power is through how many filters it has and the air filter types are used. In this Rabbit Air MinusA2 air purifier, a Six-stage air filtration works to help you remove almost any allergies and asthma problems.

  1. Pre-filter – The polluted air must pass through a pre-filter, there it will capture all large particles, along with dust mites and some of pet hair. It is washable and permanent.
  2. Medium Filter – Traps large pollen, pet dander, mold and dust particles that is small enough to bypass the Pre-filter.
  3. Advanced BioGS HEPA Filter – It is a True HEPA filter that captures 99.97% of down to 0.3 microns allergens, virus particles, pollen, mold and fungi particles. Rabbit Air advances their air filter process, therefore prolong optimal filter efficiency and filter life of their HEPA Filter.
  4. Customized Filter – Let’s you customize the product and choose from a variety of customized filters including Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber.
  5. Activated Carbon filter – Eliminates odors, smokes and chemical vapors.
  6. Ion Generator – allows the particles to get trapped more easily by your air purifier’s filters, or to settle onto the floor where they can be picked up by your vacuum instead of accidentally inhaled. Can be switched on/off.

Rabbit Air MinusA2 is proud to show the extremely powerful 6-layer air filtration. It is reasonable, because the common air purifier only makes use of 2 to a maximum of 4 filters for air purification. The air purifier could rival Rabbit Air MinusA2 in terms of the number of physical air filters is minor, with only Austin Air HealthMate Plus. With double the pre-filtration, the MinusA2’s True HEPA filter won’t need to capture as many contaminants as others, and therefore increase the durability of this precious HEPA filter.

Most low-cost flagships don’t go far with their True HEPA filter. They only last for months. But note that Rabbit Air MinusA2 has longer lifetime due to their Advanced BioGS technology (upgrade from BioGS on previous machine models) at the heart of their True HEPA filter. This means better air filtration against any pollutants and the air purifier is now happy in up to 2 years without replacing. If you really focus on the air filters, you must admit that Rabbit Air MinusA2 is an unstoppable winner.

To perfect the air filtration process, Rabbit Air invented a Customized Filter. You can tailor this air filter to fit your needs, from Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber.

The last but not least, Rabbit Air MinusA2 makes use of an Ion Generator. It will stay as the last line of defense to trap any tiny pollutant particles back to the physical filters. Overall, Rabbit Air MinusA2 has a perfect 10/10 performance rating for air purification.

Another problem that many consumers worry is the amount of ozone emission in Rabbit Air MinusA2 could cause asthma. However, it can be switched off easily to give zero ozone emission. Even when you turn on the Ion generator (for more cleaning power), I have recorded that the amount of ozone is about 0.002 ppm, which is 25 times less than the 0.05 ppm maximum ozone safety standard set by California Air Resource Board.

However, the quality of its air filter push the cost to a whole new level with common ones. Whenever you need to change the Rabbit Air MinusA2’s filter, you need to pay from $89 for a kit of HEPA and Customized Filters. Though the cost is a bit higher than the Blueair Classic 480i‘s air filter with only $59, the MinusA2 filter can last for 2 years, with a better annual filter cost of $42.5.

Rabbit Air MinusA2 Room Coverage

One thing you want to know before purchasing any air purifier is the room coverage. Also some terms like ACH (air changes per hour) and CADR (cleaning air delivery rate) will also come into your mind.

Rabbit Air MinusA2 has two editions with different room coverage. While the SPA-780 A/N can cover up to 815 square feet in your room, the smaller SPA-700A can only cover 700 square feet.

The ACH of Rabbit Air MinusA2 is 2X for normal residential use and up to 4X for allergy sufferer. Note that a 4X ACH translates to an air purifier can clean a room 4 times in a hour, which means this Rabbit Air MinusA2 will clean a room at least once every 15 minutes.

The CADR of Rabbit Air MinusA2 is 200 Dust/ 193 Smoke/ 208 Pollen (cfm), for SPA-780A version. In case of the SPA-700A version, the CADR rating is 181 Dust/ 161 Smoke/ 171 Pollen (cfm). CADR tells exactly how well an air purifier can clean the air within a particular size room. With this CADR, MinusA2 is not really good as an air purifier for 815-sq-ft room. I suggest that you should use this air purifier for a room of 300 square feet for perfect performance.

Rabbit Air MinusA2 Sound

The definition of an air purifier is literally a fan with air filters. Because it is a fan, people will want to know if it is quiet or not. For this criteria, we must give Rabbit Air MinusA2 an upvote.

Many air purifier brands were keen to shout out about their Quiet Mode, utilizing a thinner filter, a lower speed fan. Rabbit Air instead uses a Brushless Direct Current Motor technology that uses coiled copper wires along the outside in order to move the electric current along. If the current motor is not overheating, the fan will run very quietly.

That’s why it is called Ultra Quiet Air purifier not just for commercial. In fact, with 5 fan speeds, Rabbit Air MinusA2 is virtually no sound at lowest settings. The noise level is 20.8 decibels for SPA-700 models and 25.6 decibels (db) for SPA-780, which means SPA-700 is one of the most quiet air purifiers and SPA-780 is somehow good to no sound.

Rabbit Air MinusA2 Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review if this air purifier is good or not. Below is a simple comparison graph to show exactly how efficient if you have a Rabbit Air MinusA2 in your home.

rabbit air minusa2 review

The power consumption of Rabbit Air MinusA2 is just 7 to 47 watts (for SPA-700) and 7 to 61 watts (for SPA-780). This difference from the lowest to highest is due to the speed of fan settings. For an air purifier with 5 fan speeds, the maximum power consumption of 61 watts is really low, providing that others in same price range needs much power. The Blueair Classic 480i needs 90 watts to operate at the highest fan speed, or the Austin Air Allergy Machine runs at 132 watts.

I believe that is enough to prove the Energy Star certification of this air purifier. Normally, Rabbit Air MinusA2 costs you from $17 to $25 a year for running it 8 hours per day in the highest settings.

Rabbit Air MinusA2 Additional Features

Rabbit Air MinusA2 might have a lot going on, but I found it to be highly responsive and easy to live with. The device model has the Smart Sensor on it, to have adjust the fan speed automatically based on air quality in your room. With this technology, your air purifier will be more energy-efficient and help you save energy better.

Rabbit Air MinusA2 is also designed to be an air purifier for bedroom. With a light sensor, MinusA2 will automatically transition to sleep mode in a dark room. If you need some source of light in the dark, Rabbit Air MinusA2 will also provide a series of LED mood light on the front panel.

To control this Rabbit Air MinusA2, you won’t need a remote control. Instead, you will use its Wi-Fi function. With a single iOS application, you can control your Rabbit Air MinusA2 anywhere and anytime. However, one minus point is Android users will not have their own app to control MinusA2.

Also, you don’t need to remember the date to replace your air filters. Rabbit Air MinusA2 has a LED life indicator to remind you.
