Product review (2 stars): Not as good as other
I bought this pack of 2 BestAir CB41 wicks from the buy-it-now store here.  I did buy similar items from other vendors before and they all performed much much better than these.

I live in Arizona and the water here has high mineral content so I do use a water softener.  All previous wicks that I've used in the last several years usually lasted 3 to 6 months each.  This CB41 from BestAir works good for about 3 weeks then it just barely pickup water after that.  The humidity level output can't get much above 40% so the humidifier has to run virtually all the time to keep the house at 35%.  I'll avoid this brand next time.

Pro:  Same fit and form as the original wick; has wire inside to keep the wick from sagging; paper element seems strong and does not tear easily; plastic casing seems well made;  price is as good as I can find in other sites.

Con:  Usable life is much shorter than original wick.

06/01/2010: I've just checked the wick's paper and it seems to be very stiff and does not pick up water well.  I tried to rejuvenate it using vinegar and it was better for a few weeks.
