Product review (4 stars): BestAir ES12 Wicks... Kenmore can't hold a candle to 'em
BestAir ES12 Wicks
These are cheaper, more readily available and work better than Kenmore originals.  They do not promote mold growth.  We, being desert dwellers, run our humidifier year 'round to keep our wood floors/furniture in top condition.  These are the first wicks that we've used that don't accumulate mold/slime over time.  They seem to last as long or longer than the Kenmore products, and are delivered to our door at a good price using Amazon Prime.  No more hiking to the Sears store and trying to find an associate who knows that wicks aren't just parts of candles.
