6. Negative Ions

Negative Ions are odorless, tasteless and invisible molecules that are found near mountains, waterfalls and beaches. Some research studies show that negative ions help to alleviate depression and boost mental energy, but that's not all that these tiny molecules can do. Negative Ions help your air purifier by latching onto airborne particles, thus weighing them down. This 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.

Intelligent Purification

Three Element Sensing + Control Anywhere using Rabbit Air App

Get acquainted with our brainiest air purifier yet, the MinusA2 SPA-780N. Outfitted with wireless internet capabilities, this unit allows you to monitor air quality and control purification in your home whether you’re sitting on the couch or away from the house. Enjoy the effortless experience of clean air with this cutting edge version of our favorite machine. Learn more

Wifi-enabled Air Purifier

Rabbit Air products are in a class of air purification all their own. With highly sensitive odor and particle sensors, our advanced air purifiers detect the amount of pollutants in your environment and adjust their speed accordingly to assure the freshest air quality at all times.

(1) When it senses particles or odors in the air, the machine increases fan speed.

(2) The machine switches over to high speed until the air has been cleaned.

(3) Once the sensor detects a reduction in airborne pollutants, the machine will resume its original speed.

Our MinusA2's light sensor automatically cuts back on light pollution by defaulting to a low-energy, dimmed sleep lighting when the room darkens. When daylight returns or light levels increase, the MinusA2 resumes its normal mode.

Ultra Quiet

Energy Efficient BLDC Motor
Rabbit Air purifiers' cutting edge Brushless Direct Current (BLDC) motors are prized for their dutiful and silent work. Enjoy the benefits of a vigilant yet quiet machine that works around the clock to keep your air clean.
Our advanced BLDC Motor with inverter control that operates at five different speeds. At its lowest speed, the air purifier barely makes a sound. The absence of motor brushes makes our motor a much quieter, more efficient unit.

My Rabbit MinusA2 is so very easy to operate especially with the app. It is a beautiful unit and I am amazed how quite it is. I usually set it to the Auto feature and then I don't have to do much at all. It works flawlessly and it is super easy to move from room to room.

Fresh air fills my lungs

This is an amazing product. It cleans the air and you can tell the difference when it’s on. It works when it’s needed and is at rest when it’s not. Being diagnosed with IPF and needing clean air this product makes every breath healthy. I only wish it could have another for my basement

Proud owner of the MINUSA2 ULTRA QUIET AIR PURIFIER

I want to say how well my air purifier works. Not only do I live next to a freeway but my apartment was painted 5 years ago and I could still smell paint. I live not too far from the SoCal fires going on lately where you couldn't take a deep breath outside. I couldn't smell ANY smoke in my house because of my new purifier. My allergist says if you spend over $200.00 for an air cleaner your throwing your money away. I say fooey to him as my allergies are sooo much better now and other air cleaners didn't do the job. Excellent product. Our office has 6 of these and they have made a huge difference with all the construction going on in our building. So thankful for my air purifier!!

Thank you RabbitAir

In just a short time my wife and I have noticed a huge improvement with our seasonal allergies. I must admit being pleasantly surprised at the amount of relief we’ve experienced. My wife has stopped the over-the-counter allergy medication completely. You have a great product that lives up to the claims you make and in our case it has improved our day to day life. Thank you so very much!
