Design and Size

The incredible creativity of the Rabbit air purification team, who thought about everything, made the MinusA2 air purifier have a charming and simple look.

A handle is placed on the backside of the Rabbit MinusA2 Air purifier and will help you transfer the device from one place to another.

The thing is that you will not only be able to carry it from place to place, but this device also has a Unit Hanger, also on the back of the air purifier, and you will easily hang it on the wall or door. This advantage of MinusA2 air purifier will especially delight those who lack space. 

Rabbit Air MinusA2 Air Purifier is not that heavy and weighs 19.4 pounds. On the other hand, its premium design will allow you to place it in the most luxuriously decorated room in your apartment, and the beautiful set of lights will add an extra note of elegance to its dignified appearance.

I was so fascinated with the creativity of the Rabbit Team in general. The evidence of this is that you cannot buy the MinusA2 air purifier in standard black and white colors only, but you can choose between many different motifs from which Great Wave, Starry Night, and of course Standard White are my favorite.

Touch Buttons

Power Button is located almost at the bottom of the control panel and you need to press and hold it for 2 seconds to turn the air purifier on or off. 

Speed Button allows you to change the speed mode between Silent, Low, Medium, High, and Turbo. Fan Speed Indicator indicates which fan speed is on. I have to emphasize that Silent is the lowest speed, while the highest speed is Turbo. 

Mode and Filter Reset Button has a double function. If pressed briefly, it will switch the mode from Pollen and Auto Mode. On the other hand, if pressed and held for a few seconds, it will reset the Filter Reset Indicator after changing the filter.


The MinusA2 is a relatively small 7 x 21.4 x 20.25 inches air purifier that will perfectly fit rather tight places, and on account of its hangers, you will be able to lift it a little higher and hang it on the wall or door if you have a lack of space.

Accessories and Parts

Remote Controler

MinusA2 air purifier comes with a remote controller and two AAA-size batteries and allows you to switch between Power, Speed, Mode, and Mode Light Buttons. 

If you would like to turn it on or off, you will have to press the Power Button. To reduce the speed, you guess you need the Speed Button, switch between Pollen and Auto Mode – Mode Button, put on or off the lights or Ionizer (Negative Ion Generator), the Mode Light Button should be pressed. Therefore, you will not have to get up from the comfort of a recliner or sofa, it is enough to choose one of these options on a remote controller. 

Smart App

Rabbit Air Company established the Smart App that will facilitate the use of the air purifier in many ways. Regardless of whether you are on vacation or at work but would like to breathe clean air when you get back home, it is enough to switch on the item with the app an hour before.

Keep in mind that this feature is available only with the SPA-780N model.

Rabbit Air MinusA2 Features

Revolutionary and celestially enriched with various features, the Rabbit Air MinusA2 air purifier is a must-have device. I will bring you closer to its characteristics, which is why you will simply have to buy it immediately, so let’s get started!

6-Stage Filtration

Rabbit Air MinusA2 air purifier is a master among air purifiers. It is intended for rooms up to 815 square feet and uses a 6-stage filtration system. The Filtration System embraces a Pre-Filter, Medium Filter, BioGS HEPA Filter, Customized Filter, Charcoal Based Activated Carbon Filter, and Filter Case.

Five Fan Speeds

Rabbit Air MinusA2 is furnished with 5 fan speeds: quiet, low, medium, high, and turbo. You can switch between these speeds manually, by using the remote control, or via Smart App. However, if set on the Auto Mode, the gadget will reduce or increase the speed according to the readings on the air quality indicator and the light sensor.

Auto Mode Indicator

Auto Mode Indicator when switched on, the MinusA2 air purifier automatically changes the fan speeds according to the readings of the air quality sensor and the light sensor. Therefore, if the air quality is poor, the fan speed will be accelerated. On the other hand, it will not change if the room lacks light and the fan speed will be reduced to Silent.

Mood Light

Mood Light button is intended for dual use as well. If you click it briefly, it turns off or on the light on the front of the device, but if pressed and held for a couple of seconds, the Negative Ion Generator will be turned on or off. 

Negative Ion Generator

An additional advanced option of this air purifier that, in some way, represents another extra layer in the fight against toxic particles in the air is the Negative Ion Generator. It produces negative ions that make particles in the air heavier and thus simplify capturing them in layers of a 6-stage filtration system. Although it produces negative ions, these are not harmful to your health. 

Mainly, negative ions make people happier and satisfied, on the other side, some research shows these are effective in the fight against depression. Normally, a high concentration of negative ions is found in the forest after the rain (rainforest), on the mountain, next to the waterfalls, etc.

Pollen Mode Indicator

Pollen Mode Indicator on the fan speed will also be adjusted automatically depending on the air quality sensor reading. In addition, the mood light changes color in the following pattern: Blue > Purple > Light Purple > Red.

Sleep Mode Indicator

Sleep Mode Indicator, as its own words say, shows when the device is in sleep mode. Literally, when the sleep mode is active, you won’t hear the motor.

Replace Filter Indicator

Replace Filter Indicator – Rabbit Air MinusA2 Air Purifier is enriched with a quality 6-stage filtration system and, you won’t need to change the filter so often, basically once a year if the air purifier is on 24/7. But, when the filter indicator lights up, it indicates that you should replace your filters.

This is a very convenient feature because you don’t have to keep track of when it is time to replace the filter.

Air Quality Indicator

Air Quality Indicator is automatically connected with the Light on the air purifier and, depending on the air pollution, the Light on the front of the item will change from Blue through Purple, Light Purple, and Red Color. Keep in mind that Blue Color indicates pure air, while Red indicates highly polluted air in the room.

Particle Sensor

A Particle Sensor that is located on the right side of the device seen from the front will indicate Pollen Particles in the air and show them on the front end of the air purifier. 

Custom Filter Option

It allows you to adapt the system to your specific environmental needs. For trapping and reducing airborne bacteria and mold spores, you should choose the Germ Defense Filter. If you want to reduce VOCs, then the Toxin Absorber Filter is your best friend. Having a car, dog or, other pet involves a large amount of pet dander, so in this case, the Pet Allergy Filter is a logical choice. Odors from smoking, cooking, or pets smell can be reduced with the Odor Remover Filter.

Mode Light

Mode Light makes the Rabbit Air MinusA2 air purifier an unprecedented device. It is directly related to the air quality monitor and, depending on it, colors will change in the range of colors from Blue, Purple, Light Purple, and Red. So the Blue color will symbolize and signify clean air, while if it is light Red, that means that the air quality in the room is hazardous.

At the same time, Mode Light of Rabbit Air MinusA2 air purifier contributes to its aesthetic look, especially in the evening, when it becomes an elegant Night Light, and this option can also be switched on or off as per your wishes. 


The MinusA2 air purifier has passed many tests and has an asthma & allergy friendly® special edition certificate confirmed by the Asthma and Allergy Foundation of America (AAFA). In order to pass the numerous tests it was subjected to, the Rabbit Air MinusA2 air purifier proved to be excellent in fighting all harmful particles that can be found in the air and deservedly received the character of asthma & allergy friendly® device.

It does not produce ozone as well, so it is absolutely safe for usage.

Rabbit Air MinusA2 Air Purifier Filters

Rabbit Air MinusA2 Air Purifier is intended for use in up to 815 sq. ft. room size and it’s equipped with 6-stage filtration, which is more than enough to save your lungs from all toxic particles that can be found in the air. 

Rabbit Air MinusA2 Air Purifier - Filtration
Rabbit Air MinusA2 6-Stage Filtration System

This is a quite powerful device and it will purify 6.520 cubic feet of air in only 30 mins.


The first stage of filtration is certainly a Pre-Filter. Its key point is capturing larger particles that can be found in the air, such as hair, and extending other filters’ service life at the same time. This is a permanent and washable filter, and based on a 24/h operation, a Pre-Filter should be cleaned every month. In this way, you also maintain the other filters and extend their service life as well.

Medium Filter

Medium Filter is the second stage of filtration, and its purpose is to reduce airborne particles which are larger than 1 micron, that include pollen, mold, and pet dander. If used 24/7 should be replaced every 12 months, and cleaning is not recommended.

BioGS HEPA Filter

BioGS HEPA Filter is the third stage of filtration, and it is a trap for the smallest and filthy particles through the use of an advanced and proprietary fiber material it was made of. if you leave your MinusA2 air purifier to work 24/7 will need a 12-month change, and, like the other filters, this filter shouldn’t be cleaned. 

This is a patented technology from Rabbit Air, and it is rated as a True HEPA filter, which means it will reduce 99.7% particles as small as 0.3 microns. According to lab tests did by Rabbit Air, this filter will reduce the growth of bacteria and viruses on the filter. Test data shows it will kill influenza virus(H1N1), Escherichia Coli, and Staphylococcus aureu.

Customized Filter

The fourth stage of filtration is Customized Filter, which is basically a purpose-based filter that you can buy separately and put as a stage of filtration. There are four different filters to choose from Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber. If it is used 24/7, it will require more frequent replacement, which in this case, as in the previous ones, is every 12 months, and cleaning is also not recommended.

Activated Carbon Filter

Charcoal Based Activated Carbon Filter its advanced Carbon Filter reduces VOC and odors such as cooking smells, cigarette smoke, toxic substances that evaporate from everything around you, such as freshly painted walls, furniture, and more. As with all the other filters, it’s recommended to change this filter after 12 months of use if the air purifier operates 24/7. 

What I like most about the fifth stage of filtration is that the carbon filter is granular and heavier, which means it can adsorb a significant amount of toxic gases from the air.

Rabbit Air Customer Service & Company

Rabbit Air offers 24/7 customer service, so I wanted to give it a try. Immediately after I contacted them via chat on their website, they responded within less than 20 seconds. Their quick response proved that they care about their customers, mainly because they are very knowledgeable, reliable, and helpful and have cleared up all doubts I had.
