Other brands boast a True HEPA filter, but the MinusA2 (SPA-780A) comes with a different filtration system. In fact, this product is equipped with 5 separate filters, which include the following:

  1. Pre-Filter
  2. Medium Filter
  3. BioGS HEPA Filter
  4. Customized Filter
  5. Activated Carbon Filter

As you can see, the most notable of these filters is the BioGS HEPA filter, which, as advertised is able to trap allergens and particles that are 0.3 microns in size.

Another notable filter is the Customized Filter. Depending on what type of particles you’d like this air purifier to focus more on, you can choose among the following: Germ Defense Toxin Absorber, Pet Allergy, and Odor Remover filters.

Wall Mountable

We’ve already said this in the beginning, but it needs repeating because there aren’t a lot of air purifiers out there that has this functionality.

Customized Panel

In this part of our Rabbit Air MinusA2 review, we give you a summary of what previous buyers have said about their unit, which includes its pros and cons.

Here are some answers to FAQ’s related to the MinusA2’s performance in at least two areaa: odor reduction/elimination and air purification.

Does this air purifier remove cigarette smoke?

Understandably, this is one of the most asked questions. After all, you don’t want your house to reek of smoke, especially if a family member is a regular smoker.

Based on literature available online such as this one from the American Filtration and Separation Society and this one from the Aerosol and Air Quality Research (AAQR), cigarette smoke has a size that can go as large as 0.2 microns (or about 200 nm).

This unit’s BioGS HEPA filter is advertised to be able to trap particles of up to 0.3 microns, so theoretically, it can’t do well in eliminating cigarette smoke.

On a side note, it may help in reducing odor (e.g., pet odor), but don’t expect it to be 100% effective.

Can it help with people suffering from pet allergies?

The general consensus is that, yes, Rabbit Air MinusA2 air purifier can help people suffering from pet allergies by helping filter in and eliminate pet dander and even cat litter dust.

Can this air purifier work in multiple rooms?

No. It’s ideal for living spaces of up to 815 square feet. However, since air diffuses from one room to another, the MinusA2 would clean the air that it traps in the room that you placed it in.

Does it produce ozone?

The MinusA2 (SPA-780A) is equipped with a negative ion generator that you can turn on or off. When it’s off, this air purifier emits zero ozone.
However, if you decide to turn it on, expect the ozone output to be about 0.002 ppm on the low-fan speed setting. According to Rabbit Air, this amount is “25 times less” than the 0.05 ppm maximum ozone concentration safety standard.

Is it quiet?

The general consensus is that yes, it’s quiet. However, you may find that the turbo speed option can be pretty loud.


  • If you’re looking for a non-China made air purifier, this is one of them. According to Rabbit Air, the MinusA2 is manufactured in South Korea.
  • The Customized Filters have gained positive feedback from previous buyers.
  • The unit feels sturdy and well-built.

Our Recommendation: Rabbit Air MinusA2 Review

Let’s end this Rabbit Air MinusA2 review right. Should you make a purchase? Here’s what we have to say.

Purchase it with reservations. The MinusA2 (SPA-780A) is an attractive air purifier that you can either mount on the wall or put on the floor. It helps clean the air and is a great help for allergy sufferers. The biggest oops, however, is its ability to rid the air of cigarette smoke. It may reduce smoke, but not all of it as what others have experienced.
