Full product description
A carbon pre-filter for Idylis air purifiers IAP-10-200 and IAP-10-280, the models that take the Idylis "C" carbon filter. It replaces Idylis part 302656 (IAF-H-100C) and measures 6-5/8 x 11-3/4 in.
What it does
It sits in front of the main filter and catches larger dust and lint so the main filter lasts longer. The carbon helps with household odors.
Care and replacement
Clear the surface with your vacuum's brush attachment every couple of weeks, and fit a new pre-filter every 4 to 6 weeks.
Is this the main filter?
No. It's the carbon pre-filter only. The main filter is a separate part.
Which part numbers does it replace?
Idylis 302656, also listed as IAF-H-100C.
