These filters are great- however I do notice this last batch I bought have been buying for ~2 years now I went through them much quicker. Not sure if that was a product of drier air and the fires/smoky air outside... but these seemed to last for less time. Overall happy with these filters though!

This is an updated version of the same filter I have always used. Haven't used yet in this milder climate. Hopefully it is a good upgrade.

The Honeywell HCM 350 is by far the best humidifier Ive ever owned. A lot of companies offer after-market replacement filters. I prefer to buy Honeywell-made filters. And buying directly from Honewell is as good a deal as I find anywhere.
