Negative Positive
Title: Placebo?
Review: I was sick of waking up every morning with red eyes and a stuffy nose, but I didn't want to dump a lot of money into an air purifier I wasn't sure would work (some of the similar looking purifiers out there cost $200-$300). So needless to say, cost was a factor in my choice of this Holmes purifier. And...I guess it's working (?). I left it on in my bedroom all day every day for about a month, and I sometimes wake up feeling less congested, but mostly I feel the same, so I can't tell if it's some sort of placebo thing. If you're looking for something that's going markedly alleviate your allergies, don't bother with this one (I can't speak for other companies/models). But it does seem to help a little.
Is the review positive or negative?
