Having a cat and springtime allergies is no fun. I wake up congested and stuffy, wheezing and barely able to breathe when I'm home. Luckily, with this air purifier, I've been having a better night sleep and I don't have to suffer during the day when I'm home! The air purifier circulates fresh air into the condo and keeps my allergies at bay while allowing me the freedom to do whatever I want, when I want.
