    Cleaner household air system

    Blue air was recommended to me when I visited my cousin & her family in Phoenix area, AZ. She developed the debilitating Valley Fever (coccidioidomycosis) from the sand storms over her life while living in AZ. This air filtering system was one system that helped her live a longer comfortable life into her eighty’s. I bought into this air filter system with my allergies and with the worsening climate change causing local & state land fires in my state of Oregon.

    Classic 400 Series Filter Performance

    In our house I used 2 Series 400 filters, a dual protection filter in a master bedroom and a particulate filter in a family room. I found both filters effective in improving room air quality resulting in well controlled asthma while using only low levels of medication.

    Quality Protection

    The Classic 400 Series DualProtection Filter has been in our home for years now, and it does the job well. We particularly like how quiet it is on the lowest setting.
