The RabbitAir BioGS is a high quality air purifier. It features a certified HEPA filter. A HEPA filter is a necessity if you are considering an air filter to help with allergies. HEPA is an acronym for High Efficiency Particulate Air, and for a filter to earn this acronym it has to remove 99.97% of micro-particles in tests. In addition to a high quality filter, the BioGS has a number of features like different operative modes, a timer setting and a gas monitor as well as a dust indicator.
The RabbitAir BioGS is marketed as running extremely quiet. Considering the typical nose level of air purifiers this is a huge advantage. Many people want to use an air purifier in their bedroom at night but find it impossible due to the noise level. The quiet operation of the BioGS was the main reason why I decided to buy this particular model when I was shopping for an air purifier.
Another unique feature of the BioGS is a negative ion generator. Negative ions are tiny charged particles that will attract pollen and dust particles until they clump together and fall to the ground. This helps create fresher air as these particles can no longer be inhaled.
With the RabbitAir BioGS promising a wide range of features and long filter life I decided to pay the extra money for a high quality air filter. I was looking for air filters in an attempt to control persistent sinus problems that have interfered with my sleep for several decades. Since my symptoms were worse at night it was important that the unit could be run in my bedroom without waking up my family.
