Will this futuristic unit triumph or is it style over substance?

Our verdict:

Rabbit Air has gone full-on making this air purifier either blend into your home or be the centerpiece of any room. Boasting a 5-stage BioGS® HEPA filtration system, highly sensitive odor and particle sensors, WiFi compatibility, app control, and cutting edge Brushless Direct Current (BLDC) motors, this unit covers most bases when it comes to purifying the air in the home. This wall-mountable unit may not be the simplest to set up and get your head around, but once you do, you’ll see why it’s worth the price tag.

With one look at the MinusA2 and you’ll realize that Rabbit Air is trying to do something different. In a market full of white boxes, the MinusA2 takes air purifier design to the next level with their innovative way of living comfortably with a unit in the home.

Coming in at just over $600, the MinusA2 is aimed at an audience who appreciate the finesse of design and those who love their gadgets with features…lots of features.

As with all our hands-on reviews here at HouseFresh, we bought this unit with our own money so we have no biases to give a better review than we would under normal circumstances.

The Look

Okay, so I’ve already gone on about the design of the MinusA2 but let’s take a closer look.

We opted for the black version over the normal white model because let’s face it, it looks so much cooler but if you’re more into decorative aesthetic, Rabbit Air have you covered. There are five other designs to choose from (not colors…designs) that will transform your air purifier into a functional piece of wall art.

As soon as you pull it out of the box, the MinusA2 looks and feels smooth and modern. The shiny gloss front panel holds a Knight Rider-esq light bar which stretches across a large majority of the unit. Down the front right-hand side is where the controls live along with more lights and indicators.

You’ll know exactly what’s going on in your home with the unit’s quality sensor, auto mode, fan speed control, and ionizer.

A great feature of this unit is the ability to have it free-standing or wall-mounted. You receive all the parts you’ll need for both options with no need to buy any extras as well as a remote control. If you choose to have it freestanding, it measures just 19.25 inches in height which means it won’t be towering over anything, and (size permitting) you could even have it on a desk or table.

Operation

After much deliberation, we decided to keep the MinusA2 free standing for the time being. We just haven’t found the perfect spot to wall mount it yet. This way we can move it from room to room without committing to one particular space.

The control panel is all labeled and extremely easy to navigate. There are five fan speeds to choose from from ‘Silent’ to ‘Turbo’ which pretty much do exactly what they say. Silent mode gently hums away and, if I’m totally honest, doesn’t really do much at all whilst Turbo is the highest speed making a noticeable amount of noise and a noticeable difference to air quality.

We found that for general use, Auto mode worked better for us. When you set it to Auto, you can basically forget about it and let it do its job. We noticed the fan speed and air quality sensor changing when we were cooking and when we were moving around the apartment more than usual. 

A great feature of the Rabbit Air is the light sensor. When testing the unit in the bedroom overnight, we noticed that when you turn the lights out, the A2 will turn its light out so it won’t disturb your sleep.

I’ve noticed from other reviews that the jury is still out on ionizers. I figured that if they included it in the unit, it can’t be harmful to you. As you can’t see it actually working, you have to put your faith in the unit. We did notice a difference when engaging Ion mode after cooking. The unit seemed to clear the air of odor faster with it on than without it. 

Filtration

This is where Rabbit Air stands tall over other brands. The MinusA2 comes with a large six-stage filter to battle airborne contaminants which fits snug in the front of the unit.

  • Stage 1 – Pre-filter: The pre-filters main task is to capture larger airborne particles like dust mites, pet hair, and pollen. This filter is hand washable which means it not only doesn’t have to be replaced with the other filters, but it actually prolongs their lifespan (if you wash it regularly of course).
  • Stage 2 – Medium filter: You don’t commonly find a medium filter on a lot of units so this is definitely a bonus. It’s designed to take care of particles larger than 1 micron like bacteria, mold, and dust particles. Having a medium filter means the HEPA filter doesn’t have to work as hard and should last longer.
  • Stage 3 – BioGS® HEPA filter – A HEPA filter has the most important role in any air purifier worth a damn. This is the guy that removes the tiniest particles out of the air to make it clean. The BioGS® version is an advancement on HEPA technology, trapping 99.97% of allergens and particles 0.3 microns in size. Basically, whatever sneaks through stages 1 and 2 will be caught here.
  • Stage 4 – Customized filter – The MinusA2 allows you to tailor the unit to match your needs. Each of the 4 customized filters is engineered to tackle different types of contaminants. You can choose from; Germ Defense, Toxin Absorber, Pet Allergy, or Odor Remover.
  • Stage 5 – Activated Carbon Charcoal filter – Rabbit Air claim that their filter is more effective than typical AC filters. It reduces chemicals and odors in the home like vape/cigarette smoke, VOCs, and cooking odors by trapping them in its layer of activated carbon.
  • Stage 6 – Negative Ions – Not strictly a layer of the filter, these invisible molecules released from the unit latch onto contaminants weighing them down. This makes them easier for the filters to trap or pull them onto the floor to be picked up with a vacuum.

The (dreaded) filter replacement indicator is located on the side of the control panel. The light is pretty small so you’ll have to keep an eye on it. Rabbit Air state that you should replace the filter every 12 months if you’re operating the unit 24hrs a day. 

I’ve found you can prolong the filter life by regularly cleaning the pre-filter and making sure you vacuum and dust on a more regular basis.

It’s easy to find replacement filters online. You can buy the official MinusA2 replacement kits or unofficial kits if you’re on a tighter budget. I haven’t seen the unofficial filters in action, so I can’t comment on how they compare.

Noise 

Noise is always a key factor for me. As the fan spins around collecting all those harmful toxins it starts to generate noise and if it’s too loud, it’ll deter me from turning the unit altogether. 

On Silent mode, you can hear the fan gently hum away which is great if you have it in the bedroom as it won’t keep you awake. Turbo mode on the other hand is where the MinusA2 really ramps up. Unfortunately, it does get quite loud and noticeable even over the TV. It’s no jet engine but there are quieter units out there.

Here’s a video to demonstrate and a table to show how it compares to some of the other units we’ve reviewed.

App

You’d think it would be standard practice to have wireless capabilities with air purifiers by now but it still seems to be an extra feature (I hope this changes soon). The MinusA2 has these capabilities and Rabbit Air have created their own app for their units. 

You can download the app from Apple’s App Store or Google Play for Android. There’s even an option to use Alexa if you like shouting commands from across the room.

You can connect to your machine from the comfort of your couch or away from the house completely. Here you can remotely turn your unit on/off, check the current air quality of the room, change fan speeds, and engage auto mode.

Pretty handy if you want to make sure your room is fresh before inviting people back from the bar.

The app is probably great…when it’s working.

At first, the unit wouldn’t connect to my wifi at all. Eventually, when it did connect, it would work for a while then disconnect by its own free will. This is something that kept happening until I got to the point where I didn’t use it all. I hope Rabbit Air does an update soon as having this function is extremely useful.

Pros

  • Its design fits into most modern decor
  • You can mount it on the wall or leave it freestanding
  • It comes with everything you need for wall mounting
  • The customized filter is a great feature for those needing an air purifier for specific reasons
  • It comes with a 5 year warranty incase of any mishaps

Cons

  • The light on the front can be quite distracting if left on
  • The control panel buttons are quite small

Bottom Line

All said and done, this unit is a hard worker and looks great. Its six-stage filter system makes light work of airborne pollutants and you can see it working with its air quality indicator. 

Yes the app can be a little pragmatic and the buttons are kinda small but it more than makes up for these when it’s cleaning rooms up to 815 sq. ft.

There are better units out there but this fits perfectly well into creative spaces, apartments with not much floor space, and those who want their gadgets with a little more style.
