RabbitAir BioGS 421A Purifier
Spring has always been one of my favorite times of the year, being able to open up the house for the fresh air coming in. For my wife, I realized this was not exactly the case as her allergies can be hard to overcome (or the allergy medicine can be troublesome). Instead of taking medicine she made an appointment with her allergist and they actually referred her to a site that sells Rabbit Air purifying machines.
In the past we've dabbled in Ionic Pro purifiers but we found them to not make too much of a difference as allergies were still hard to stop from the pollen and all the dog / cat fur. When we picked up the RabbitAir BioGS 421 Air Purifier the first thing we noticed was the amount of work it did especially considering how quiet it was. Other air purifiers we've had sound almost like a fan on a high setting but Rabbit Air purifiers were easy to sleep through.
On the RabbitAir BioGS purifiers there is a sensor for when pollen, odors and dust are in the vicinity. For people with allergies or asthma this unit is a must have. In the past it has been listed for over 550$ but it has since been reduced to low $300's. The HEPA Filter lasts forever and the performance of the RabbitAir Bio GS has not deteriorated over the time we've had it. Even so it comes with a 5 year full warranty. For use we tend to just leave it on auto mode, as it picks up speed when it senses dust / odor / pollen and then runs efficiently while it is idling.
