All products from Rabbit Air have a modern design. These air purifiers are not some ugly box with a ventilation and filter. And design of this particular model is one of the best. Rabbit Air BioGS 2.0 looks more like a robot standing in the corner than some trash can waiting for dust.


Since the company is making modern futuristic products, then this is no simple air purifier. This air purifier has many options that can be turned on or off. But at the same time, this options and the whole process of purification can be set on automatic, and you will not need to bother with any of the options. If you prefer playing with the air purifier, then you can choose from various options.

First, you will need to click auto mode off. After that, you can select fan speed between 3 levels. If you wish to save some energy by shutting down after some period you can choose that as well. You can also turn negative ions on or off. Negative ions, when turned on, will make air purification faster and will trap more pollution from the air.

With Biogs 2.0 you can also check air quality in real time on the air quality indicator. In case air is terrible you can turn negative ions on and put the fan speed on maximum or just turn on auto mode. On auto mode, the air purifier will change speed and options depending on the air quality in the room

True HEPA Filter or BioGS HEPA Filter

When an air purifier uses true HEPA filters that means that they are removing 99.97% of the airborne particles. Both of this HEPA filters are having the same efficiency. Both of them will capture everything that is larger than 0.3 microns. But BioGS has extra powers, and one of them is a reduction of allergens trapped on the filter.

With BioGS technology the filter in air purifier will not be polluted with pollen, dust, pet dander or another type of pollution too fast and that just means that efficiency of BioGS filters is prolonged comparing it to standard true HEPA filters. Some air purifiers with true HEPA filters may have viruses and bacteria on the filter.

This filter pollution is possible if you are using filters for a longer time. True HEPA filters need to be replaced with time, and if you forgot to replace them viruses, bacterias and allergens might be caught on the filter, and the filter will not work correctly. In fact, it is possible that air purifier with such a dirty filter may be the source of air pollution. Because of that if you are suffering from allergies or have any kind of respiratory problems that require breathing fresh air, please choose the BioGS filter because it may help you more than the standard true HEPA filter.

As you already get the whole picture about BioGS HEPA filter I need to say that in a same dirty room BioGS filters will stay cleaner than the true HEPA filters. This ability may give you more efficiency at the time.

BioGS Hepa Filter in Action

There is not much difference in a work of BioGS filter and standard true HEPA filters. The air purifier has pre-filter which will trap bigger particles like pet hair or even dust mites. Pre-filters in Rabbit Air BioGS 2.0 are permanent and you can clean them with water or use a vacuum cleaner on them.  After that comes BioGS HEPA filter and this filter will catch a lot of things; mold, fungi, dust, pollen, dander, bacterias and even viruses. BioGS filter will also help with pet allergens, odors, and fumes.

But the real eliminator of the odor is activated charcoal carbon filter. Carbon filter in Rabbit Air 2.0 is sturdy and can remove greenhouse gases, VOCs, smoke and all kind of smells efficiently and fast. The efficiency and power of activated charcoal carbon filter come from its size. And the size of that filter is significant in this Rabbit Air air purifying model.

And on the last stage of air purification comes negative ion generation. Negative ions will reduce lousy odor and smells as well as make the particles in the air heavier. These heavy particles will then be caught easier. Because of this power to make smaller particles bigger more and more air purifier manufacturers are including ion generators in their systems.

Rabbit Air BioGS 2.0 Replacement Filter

Standard true HEPA filters need to be replaced every 12 months and some of them even every six months. But BioGS 2.0 filters have extended life thanks to the advanced technology that keeps pollution away from the filter. If you use the air purifier for 12 hours every day you will need to replace the filter every three years. And if you are using it 24 hours, then you should replace every 18 months. This results are surprising and will save you money on the maintenance. And if you put everything down on the paper, you will see that it is worth to pay extra dollars for this fantastic air purifier with amazing advanced technology true BioGS HEPA filter.
