I use this in my bedroom because I have bad allergy and sinus problems
I have had this for several months now.  I have not had to change the filter or anything.  It is a little noisy, but I figure that just means it is working.  I use this in my bedroom because I have bad allergy and sinus problems.  I have noticed a significant improvement in my breathing and overall health since I started using this air filter.  I love it and would recommend it to anyone looking for an inexpensive option for better air quality.  I would not recommend for large areas, but as I said, it works great in a bedroom or office.
