@pdlinda Yes, it finally changed my mind, lol..... my air cleaners will show a green light if it thinks the air is good...if it picks up a scent of sorts, it will turn yellow and red, alerting me the air is a problem. One is in where I sleep. That is all I do in that room, sleep. Oddly, if I am in a room next door in my bath tub with a bubble bath, low and behold, my air cleaner will shoot up to red.......telling me it 'smells' something....(odd imo). I don't think bubble bath is harmful nor is water.
One day I opened my air cleaners/both rooms, after about 2-3 weeks....(no light had alerted me to check the filters). OH MY.....both black/full of stuff...and I also have a carbon filter as well. I began to wonder what type of 'air' it was releasing back into my rooms, especially where I sleep. I have no pets. My windows are closed where I sleep.
So, I knew not to wait for that red alert light to appear, to change the filters. I can't afford to do that all the time. My air cleaners are positioned at opposite ends of where I live. Sort of made me mad that I spent so much on filters so I've not relied on them further.
I read if I want the air really clean, it would take a unit of a lot of money ($1,000 up). No can do.
If this TSV works for ppl, great. Might make a check on their filters after a couple weeks tho....jmho+experience 🙃
