At this price point These are the class 2 filter and carry an. More than 3 times better than HEPA down to. 1 microns which is where the magic happens. You filter out the tiniest of irritants from mold, pollens and viruses.
Less if that better suites you. And by me I mean as long as I live? I carry all models, numbers, age and condition. Can list one for any budget if this one is not for you.
Just let me know and will get you set up. Also see my ads for filter Queen Vacuum.
