I have suffered from allergies and asthma since I was a kid so I know how miserable it can be. The past few years my symptoms have been under control with medication and allergy shots. That all came crashing to an end when we learned the bunnies we adopted for our kids needed to be inside the house. I was back to being miserable and on the verge of sending the bunnies back when we decided to get this air filter. I no longer need to take my allergy medication and feel sleepy all day. I cannot put into words how much this has helped, it is amazing. I love how it will adjust cleaning levels depending on the level of pollutants in the air. Needless to say, my kids are happy to be keeping their bunnies.
