Honeywell Universal Carbon Air Purifier Replacement Pre-Filter

When we got our Honeywell air cleaner, it came with one carbon pre-filter and we were immediately impressed by how quickly the air smelled fresher once we started running our Honeywell 50250. We knew we would need to replace the carbon pre-filter every couple of months and so we ordered these. When it came time to change the carbon pre-filter, I pulled the first one out of the box and I immediately noticed it did not look like the carbon pre-filter that came with our Honeywell. And it did not give us that fresh air smell after running it. I don't know why, but these aren't as good as the carbon pre-filter that comes with the air cleaner.
