Query: Not the original filter

I ordered this filter because it showed the TrueAir logo printed right on the filter. I know all filters are not the same and I wanted to make sure I was getting the original that came with the purifier, because it works great. I was very disappointed when it arrived. The filter is a very cheap one made with wire and I am sure it won't work as well. They should not show the logo if it is not the real thing.
