Rabbit Air MinusA2 Review

Rabbit Air MinusA2 color options

Few air purifier brand names spark interest today quite like Rabbit Air. Their units utilize the latest filtration technology, and they blend into homes unobtrusively. The Rabbit Air MinusA2 is one of the company’s latest, and greatest designs. It offers everything you’d expect from Rabbit Air, along with unprecedented levels of customization.

Multistage Filtration

Rabbit Air MinusA2 Review - Filter Stages

The Rabbit Air features a BioGS HEPA filter, but that is neither the first nor the last step in the system’s filtration process. Most air purifiers have about three different filters. The MinusA2 has a total of six filtration steps.

Pre-Filter & BioGS HEPA

Before the HEPA filter, there is a pre-filter and a medium filter. Each removes progressively smaller particles. This extends the life of every filter in the system. The BioGS HEPA filter reduces common allergens more efficiently than regular HEPA filters. Since filters literally collect bacteria, viruses, and particles that feed them, many good filters become breeding grounds for the bacteria and viruses they are meant to stop. The BioGS helps stop this growth in its tracks.

Four Filter Options

After the HEPA filter, buyers can choose between four options. Each option is engineered to address a specific issue. A germ defense filter is the perfect choice for those with delicate health. The toxin absorbing filter keeps air clean in new homes and office environments. For allergy sufferers, there’s a pet allergy filter. The fourth option removes odor, which may be favored for farmhouses and crowded apartment complexes.

Activated Carbon Filter

An activated charcoal filter stands as the fifth filter. Typically, activated charcoal works to absorb odors, and it would work especially well when paired with the odor absorbing option as the fourth filter. Right after the carbon filter is the final step, a negative ion generator. This charges particles so they sink to the carpet rather than floating into your lungs.

Rabbit Air MinusA2 Replacement Filters

Rabbit Air designed these filters to be economical. Many families hesitate to buy air purifiers due to the high cost of replacement filters or fail to replace filters as often as they should in order to save money. The MinusA2’s filters last up to two years. By extending the life of the MinusA2’s filters, Rabbit Air makes their product a realistic option for more buyers. If the unit operates an average of twelve hours a day, then the yearly filter costs weigh in just over forty dollars per year.

Air purifiers are, by and large, designed for function over fashion. Rabbit Air is working to change that, though, and they go far and beyond making air purifiers unobtrusive. The company has actually elevated their machines to art. Interchangeable covers allow users to disguise their air purifiers with original Rabbit Air designs or reproductions of classic artworks. Some of the best works of Klimpt, Hokusai, and Van Gogh transform any unit from an eyesore into a piece of décor.

Wall mount options help further disguise the air purifier. Although the unit weighs almost exactly twenty pounds, it comes with special instructions to help users hang it on the wall without ripping a hole in the drywall. The flat design helps the purifier blend in on end tables and mantels, too.

Rabbit Air MinusA2 Wall Mount

The MinusA2 looks great mounted to a wall, or on the floor.


The Rabbit Air MinusA2 handles seven hundred square feet of air for regular household use. For severe allergy sufferers, however, the MinusA2 is most effective in a closed space up to three hundred and fifty square feet. This is the difference between a small apartment and a small bedroom with the door shut. The unit would work well in a limited open floor plan, and it would keep a single bedroom’s air pristine.

Energy Use

The MinusA2’s energy use has a lot to do with the setting you choose. The unit can use anywhere between seven and forty-seven watts. The motor is Energy Star rated. Light sensing and automatic modes schedule and adapt to changing environmental factors for energy savings. In light sensing mode, the unit turns off whenever the room goes dark, which is great for anyone disturbed by noise as they sleep. The intelligent automatic mode adjusts fan speed based on air quality.

Warranty and Support

Rabbit Air stands behind its products, and customers have great coverage for the first several years of ownership. In addition to 24/7 customer service, the MinusA2 comes with a five year warranty. This goes well beyond a satisfaction guarantee. This warranty ensures your investment is protected. Paired with the great customer support, users can relax and enjoy their clean air.

Customer Sentiment

Users almost unanimously praise their MinusA2. Many mention its power to combat serious allergies, and everyone enjoys its discrete appearance. Some users claim the MinusA2 is so quiet, they could only tell the unit was running by the feel of air flowing out the top. While a lot of automatic settings have gotten mixed reviews in recent years, Rabbit Air did extremely well with this model’s sensors. Previous buyers told stories of their units automatically turning on or shifting to a higher setting when smoke came from the kitchen, or when windows opened. Some users found the filters didn’t last as long as expected, but there are too many variables to determine whether that was the fault of extremely poor air quality or failed promises on the part of the manufacturer.

Pros & Cons


  • Six stages of filtration
  • Advanced Hepa filter

  • Customizable fourth filter
  • Attractive overall design with lots of custom designs

Final Thoughts on the Rabbit Air MinusA2

The MinusA2 is not only a great Rabbit Air product, but it’s arguably one of the best air purifiers on the market. Although the upfront costs set this unit towards the higher end of the price scale, it’s designed to save money throughout its lifetime. The Energy Star rated motor uses less electricity, and the filters need infrequent replacements.

What really sells this item is the customer sentiment. It’s rare to find so much praise across the board. Nothing tells potential buyers more about the value of a product than the experiences of similar users. Allergy sufferers have the most to gain from this second hand reporting, but the feedback proves the Rabbit Air MinusA2 is for everyone.
