“Don't realize much difference”
“So far I don't see a difference in the air quality in my condo. Not sure they were worth the money.”
“Can’t tell any difference. Sorry”
“Honestly I do not see or feel any difference and I have had my 3 devices plugged in for at least 2 weeks.”
“Haven’t felt or seen a difference”
“I bought it because of my asthma too early to say just got it a little while ago”
“No replacements needed....air feels lighter..just plug it in!”
