“I bought this because I am allergic to dust, cat hair, mold, and other allergens. I placed it in my bedroom and keep the door closed at all times, and I can definitely tell that the air is cleaner and it’s easier to breathe. I sleep with a CPAP machine, but it still purifiers the air enough so that my head doesn’t get clogged up and stuffy at night. I am going to get one for another family member.”
