Replacement Universal Carbon Prefilter

Customer Reviews:
easy to fit, easy to remove, easy to buy!
....what's to review? yeah, it's a pre-filter. Nothing that's really performance related to talk about here, so I'll just say they are easy to fit, easy to put on, take off, and if you buy enough of them to get free shipping from amazon, they're a pretty good deal!

Just a little better than nothing
If I knew the filter replacements were going to be this crappy, I'd never have purchased the 17000. The filter, to work right, has to be doubled. That effectively doubles the price of the filters. The filters themselves look moth eaten, weak and flimsy, cheap and really laughable. Good old american product made by ebaneezer to save his buck and take ours.

Honeywell Universal replacement pre-filter
This filter(from honeywell) still shed lots of carbon (black) particulate, especially when you have to cut to trim to size. These are very fine dust particles. Some of which i am sure clogged the HEPA.
I dont believed previous report that said the Honeywell brand of pre-filter dont shed.
