Still Good, Not Quite The Same
on March 29, 2014
I still have one of the older versions of this Air Cleaner. The front panel on the old one has 2 rings of holes for front intake, not just from the sides and bottom like the new one I just got to replace the old one because its' time had come. I just hadn't gotten rid of the old one yet.
The new one also hummmmms on low. The old one? On medium I'd hear it, on high obviously I'd hear it, kind of like a box fan on high - there is no getting away from that fan noise! But the old one I could put in my bedroom, put it on low at night and be able to go to sleep and not hear a thing. The new one I can't have in my bedroom at night, the hum drives me crazy - I have a combination of fluctuating hearing loss/everything's too loud (meniere's disease) that hits when it wants to.
While this is still a very good air cleaner, simple, direct, no ionizer or ozone (people with heart or breathing problems should NOT be around those things and imho they just don't do much but put a weird smell in the air) and this does help keep the dust down in the part of the 100+ y/o house I'm living in right now. I'm hoping that eventually I'll be able to tune out the hum when the unit's on. It helps cut back on tedious dusting, helps keep the inside of my computer cleaner, helps me breathe a little easier, makes the air feel and smell a little fresher. So that's all good. I just hate that 3M is charging this much for something that appears to be a fairly simple appliance and has managed to cheapen the building quality of it - while keeping the price up.
Filters ... no you won't find filters for these in the stores, that's been a problem for years. Get them here or look for fast filters ;) and do vacuum your filter when you vacuum your room (do mine once a week to once ever other week depending on how I'm feeling). It'll help extend the life of your filter and help keep any at least larger dust/hair/whatever out of the Air Cleaner and out of your house.
