smaller than a 12 in cube
designed for 100 sq ft room
replacement filters $20-25 (about every 6 mons)
But does it work? And work well?
Going on reviews, yes it does!
The main issue is it is size limited.
A few have tried in a room larger than 10 x 10 and have to keep it cranked up on high and it’s too loud.
That’s not good for the machine either.
An interesting hack I ran across last summer but have not tried:
Take a standard box fan ( the big ones)
Find a 3M furnace filter that is large enough to cover it’s intake side at your local hardware or big box store
Seal the edges with tape. Turn on.
It really works! Cheap!
If you add this little guy to that, possibly won’t be overwhelmed in a larger size room…
