Product review (3 stars): I just can't handle wick humidifiers anymore!!!
I kind of hate wick humidifiers now, so I might be biased here (I just ditched my wick humidifier for a filter-less warm humidifier, which I like much more). Wicks are expensive and, from what I've seen (and it may just be our water) they go disgusting way too quickly. And I wasn't about to buy any humidifier additives to extend the wick's life (and possibly shorten ours from breathing chemicals). They're also messy (duh, they get sopping wet) if you have to remove them to clean the humidifier. I tried adding grapefruit seed extract as an anti bacterial to the water tank, but it didn't help. So, in summary: expensive, messy, and maybe a little too effective for their own good since they'd get gross quickly (hopefully from doing an excellent job of pulling yuckies out of the water).
