Key Differences: Rabbit Air BioGS SPA-625A vs MinusA2 SPA-780A

Here are the key differences between these two Rabbit Air air purifiers.

Design and Weight


Check Price » BioGS SPA-625A

The first most important difference is their design, and we’re not just talking about the shape of these air purifiers.

One, the MinusA2 SPA-780A have the advantage of being either a stand-alone appliance or a wall-mountable air purifier. If you want to use it in multiple rooms, the stand-alone option is definitely the more practical of the two. All you have to do is to slip in its foot stand for stability. However, if you want it to be permanently positioned in a particular room of the house, you can choose to mount it on the wall.

The BioGS SPA-625A is a stand-alone air purifier. Unfortunately, it can’t be mounted on the wall.

Two, the SPA-625A is a 16.6″ x 22.2″ appliance whose shape can be likened to a modern backpack. With the SPA-780A, it can be mistaken as a medium-sized flat screen TV.

Which air purifier is heavier?

With a weight of 19.4 lbs, it’s the SPA-780A. On the other hand, the BioGS SPA-625A is 16.8 lbs.

Another important difference between these Rabbit Air air purifiers is their filtration system, or more accurately, the number of filters they have.

The MinusA2 SPA-780A has 5 filters, which include the following: pre-filter, medium filter, BioGS HEPA filter, customized filter, and charcoal-based activated carbon filter.

On the other hand, the BioGS SPA-625A only has 3 filters: pre-filter, charcoal-based activated carbon filter, and BioGS HEPA filter.

Based on what we’ve presented, there are two filters that the SPA-780A has that you can’t expect in the SPA-625A. These are the customized filter and the medium filter.

What do these filters do?

The customized filters are filters that target specific types of particles. You can choose among these four types: Toxin Absorber, Pet Allergy, Germ Defense, and Odor Remover.


There are several functions/features that the MinusA2 SPA-780A has that you can’t find in the BioGS SPA-625A. We list them down below.

  • Pollen Mode
  • Mood Light
  • Sleep Mode

On the other hand, the BioGS has a timer, a functionality that the MinusA2 doesn’t have.
