Product review (5 stars): Better than Original Filters
These are not the original filters that came with my Sears humidifier.  I have used these the last 2 seasons, after carefully ordering the originals for over 5 years.  I was worried about quality, but Sears was out and I gave these a try.  They are clearly better than the originals, so I got lucky.  You will get lucky with these filters, too.

Update: March 2018 - Another year where I only needed one set of filters for the entire season - Oct/March - These are great!
