Air Doctors

I have COPD and also have five rescue dogs so there is a lot of dust and dander floating around. I already have a 3500 in my bedroom and a 3000 where I have my computer but have had another brand in my living room. I have been so happy with the Air Doctors that I replaced the living room unit with another Air Doctor!! Easy to clean, easy to replace filters and definitely help with my breathing. I would recommend Air Doctor to anyone with breathing issues.

Great for classrooms!

We absolutely love the Air Doctor we got for our kids' classroom! It's super quiet and honestly makes the air feel much cleaner. The best part is the total peace of mind we get knowing the kids are breathing the best air possible while they're learning—it works great!
