Sena got a brand spankin’ new air purifier and it’s whisper quiet. It’s made by RENPHO. Air purifiers probably don’t reduce virus particles but they at least they give you the impression you’re doing something to keep the air clean in your home.
We had an air purifier years ago, and the whole unit had to be cleaned occasionally. This one has a filter you change every 6 months or so.
It’s easy to operate. Basically, you turn it on and forget it. Some of the directions are a little interesting. One of them is a table of what the different button symbols are. The title is “Defination.”
The list of cautions includes the instruction, “Do not place anything on top of the appliance and do not sit on the appliance.”
Why it would occur to anyone but an extraterrestrial to sit on the air purifier is beyond me.
There’s an air quality sensor light which glows a different color corresponding to how good or bad the air is in your house. Blue is very good; Green is good; Orange is bad; Red is polluted. Ours always glows a nice, comforting blue.
There’s a note below the air quality sensor light description:
“Note: Compared with professional instrument, the detecting result of this air quality sensor may has tolerance in accuracy, we suggest you regard the sensor detecting result as a reference only.”
I’m not sure how to interpret this note. Does “tolerance in accuracy” mean it has only tolerably fair accuracy, meaning good enough for government work? Would a canary work just as well?
The trouble shooting section contains an entry that might be helpful:
Problem: You can’t adjust any of the controls.
Cause: An Extraterrestrial Biological Entity (EBE) is sitting on top of the air purifier. Some EBEs are pretty finicky about air purifier settings. They might prevent you from changing them by contacting their superiors, who will abduct you and conduct various experiments using large probes.
Solution: Let the EBE have its way.
