3. 6 stages of purification and deodorization with customized filters

When it comes to the filtration system, the MinusA2SPA work in a comprehensive six-stage air filtration system that trap nearly all airborne pollutants and contaminants with enthusiasm.

The six-stage process starts with a washable and permanent pre-filter that captures large particles of dust, pet hair and allergens. The second stage is the medium filter that traps larger than 1 micron in size particles of pollen, dander and mold.

The third stage is the advanced BioGS HEPA filter. Unlike typical HEPA filters, BioGS HEPA filters are more efficient and able to capture nearly 99.97% of microscopic allergens, viruses, bacteria, pollen,mold, and fungi particles with sizes as small as 0.3 microns, and prevent their growth.

In addition to the Rabbit Air has offered customers another special filter which is customizable depending on needs. Here, you’ll have the freedom to choose from any of the four customizable options which include;

  • Germ Defense filter– a filter that is specially engineered to trap and reduce bacteria, mold and particles that carry viruses. This filter is said to be perfect for individuals with compromised immune systems like children, elderly people and those individuals who are most sensitive to particles in the air.
  • Pet Allergy – just like the name suggest is ideal for people with pets as it’s specially designed to trap and reduce pet dander and pet allergens.
  • Odor Remover– is perfect for trapping and reducing smells from pets, cigarettes and cigars, cooking,mildew and other unwanted odors.
  • Toxin Absorber – is specially designed to trap and alleviate volatile organic compounds (VOCs) and other chemicals common in new or renovated homes and other facilities.

Next, after the Customizable filter, there’s another filter made of high-grade Charcoal-Based Activated Carbon. Unlike typical AC filters, this filter is coated with a thin layer of activated carbon that’s efficient enough to eliminate household odors, smokes, and common chemicals.

And in the final stage, there’s the Negative Ion Generator. In this stage the negative ions latch onto the airborne particles to weigh them down and settle them on the floor. While on the floor, these particles can either be trapped by your air purifier or picked up by your vacuum cleaner.

4. BioGS HEPA technology

Now, the best air purifiers are the one that use the HEPA filter or equivalent filters. Such purifiers are able to remove nearly 99.97% of microscopic allergens, pollen, bacteria, and mold with sizes as small as 0.3 microns.

Designed to tackle any form of air contaminant, the Rabbit MinusA2SPA purifiers are engineered with a BioGS HEPA filter. This filter is a better and more efficient version equipped with an extremely fine mesh that allows clean air to pass through leaving nearly all air contaminants trapped in the mesh.

While BioGS HEPA filter is certified to trap nearly 99.97% of airborne contaminants with sizes as small as 0.3 microns just like the normal HEPA filters, this is also able to also reduce the growth of said allergens, bacteria and viruses on the filter. With such a filter, efficiency is generally enhanced while filter life is prolonged.

Combining this filter with five of the other stages, the MinusA2SPA-700A Air Purifier is able to guarantee you fresh breathing air at the comfort of your living space or office space.

Although they operate at 5 fan speeds, the Rabbit Air MinusA2 have managed to keep their fan sounds low making them one of the quietest air purifiers, with noise levels of just 20.8 to 45.6 dBA and 25.6 51.3 dBA for the SPA-700A and 780A/N models respectively.

They ultra-silent motor features a brushless DC motor technology. The technology comprises of coiled copper wires that operate the motor without overheating the system. With that, the fan will run very quietly allowing the air purifier to operate at an ultra-quiet mode.

Whether you’re always at home or you’re a busy folk always on the go, the MinusA2SPA air purifiers are equipped with a smart sensor so that they constantly monitor the quality air in your living room, bedroom or office space and automatically adjust the fan speed.

This technology works by increasing the fan speed whenever the sensor senses an increase in particles, odors, and allergens on the air. Once the air has been cleaned, the sensor will detect a reduction in air pollutants in the room hence adjust the machine to its normal speed.

Since air purifiers are designed to operate continuously, the smart sensor technology will allow the machine to become more energy-efficient, saving on energy than some models in the market.

8. Energy Star rated efficiency

One of the major questions most customers ask when buying an air purifier is how much energy they consume. Since these appliances operate continuously, the rate of power consumption is one critical factor that can determine whether a purifier is good or bad.

For the case of the Rabbit Air MinusA2 SPA-700A, the power consumption ranges from 7 to about 47 watts and 7 to 61 watts for the MinusA2 SPA-780A/N, with the difference being caused by the speed of fan settings.
