Adaptable to HCM-800 series Compartment (radiused)
This filter was bought to customize/modify to fit a Honeywell QuietCare humidifier model HCM-800 that may no longer be produced. I could not find it or the original filter listed anywhere on the internet - even after about an hour of searching over several days. It was relatively easy to trim to the correct size and bend to the radius of the original factory spec part. Even though the original filter was about 3/4 inch thicker than this filter it filled the filter compartment/frame adequately.
