Product review (5 stars): even though either end of these wick/filters can be up - one end fits better than the other and supports the weight better
Although fairly simple to install, some basic illustrations would be helpful - we only use the humidifier for 3+ months a year (we live in Oklahoma).
Also, even though either end of these wick/filters can be up - one end fits better than the other and supports the weight better. Why not have one end marked "up"
Pros: Good Size & Weight, appears to be durable
Cons: No Instructions, more time required to install than should be

I received "4PK Humidifier Wick Filters Fit Kenmore & Emerson, Part # HDC-12 & 14911" by Crucial Air at a discount in exchange for my review
