Reliable old school type filter
I have 2 NSA air filters that I have had for over 20 years and they still work great! I just replace the filters when needed. I like that there is nothing digital on them that can go wrong.Originally I bought them to use in my acupuncture clinic because I burned moxa there which made a lot of smoke, but the filters did an excellent job of eating the smoke. Now I am retired and just like having them in my home for clean air. Also I have a pet bird and I know clean air is especially important for birds.
