Product review (5 stars): Really Puts Water into Air; Replaces Original Filters Without Problems
Exact replacement for Kenmore humidifier, model #758.144170 console humidifier.  I have been using them for 1.5 months.  The house was down to 10% humidity due to lack of filters AND outside temperatures between -10 and 20 degrees.  I have electronic thermometers that record the min/max temperatures AND min/max humidity both inside and outside.  Even the outdoor humidity was 30% or less (VERY dry).  I live in central MA; review was written when cold snap hit us for ~2 weeks (12/22/17 through 1/8/18).
I put in these new filters and put the fan speed on my humidifier on medium and did this for 1 WEEK (3 fan speeds on my console humidifier).  Despite the cold weather and dry conditions, the indoor humidity was brought up from 10% to 45%.  After that, I put the fan speed on low and the humidifier has been operating quietly and cycling (on/off) for the past two weeks.
I use a combo bacteriostat (mold, bacteria growth) and water treatment (hard water) to improve filter operations (BestAir Golden Solution Humidifier -> found at Lowe's or on eBay).
COMMENTS on POSTS: I have a whole house humidifier (1,800 sq. ft.).  The humidity where the humidifier is located measures 48% and at the opposite end of the house (ranch style) measures 45%.  The house is heated with oil-fired forced hot water baseboard heat.  It takes time for the moisture to build up and then "filter" its way throughout the house.  I started out at 10% and using a medium fan speed had to run the humidifier constantly for a week to get the humidity levels up.  You're not just adding moisture into the air, it's EVERYTHING in your home (wood floors, furniture, curtains, etc.).
I do find that I have to fill up one water tank (humidifier has two 2.5 gallon water tanks) on a daily basis.  Some people have posted that this is excessive.  Honestly, these wicks are doing their job because in colder weather, the humidity levels drop both outside AND inside your home more excessively.  This means you need more water to get into the air as opposed to when outside temperatures are in the 40s to 60s (warmer air can hold more moisture than colder air).  I have also found that my humidifier cycles more "off" than "on" suggesting that these paper wicks are getting the humidity into the air despite dry conditions.
The filters have to put into the humidifier CAREFULLY because of a slight design flaw with the holders.  The plastic holders for my wick filters are rounded on the bottom but fit into a straight holder on the top.  Essentially, the filters are gently but noticeably being "bent" from a curved surface to a straight surface.  Like the OEM wicks, I had to put them in gently and made sure they were not wet.  DON'T try to flip these wicks to get extra life out of them.  They will generally last a whole season (get more "strained" into the fourth month of use).  When these wicks are wet, they will fall apart when you try to take them out of the holder and turn them around.  Remember, the wicks are made out of paper and paper loses its cohesive properties when wet (pick up a 3 ounce fishing weight with two pages of dry newsprint and then try the same thing with the newsprint soaking wet.  You'll be lucky if the pages don't fall apart when you handle them!).
Paper wicks may seem "cheap" but the paper weave really soaks up the water better than some of the plastic honeycomb filters I have tried in the past.  In my area, we have free recycling so a used paper wick goes into the paper recycle bin.  Environmental impact kept to a minimum.
