Thank you!
I could have sworn they had a different scent, back when my parents bought their first Electrolux.
I even contacted Aerus once, and they told me the scent has always been, and continues to be lemon.
I don't know what the original scent was, but I did like it better.
That being said, I still use the current ones. I don't dislike the scent.
One thing I'm OCD about, is that I'll only use them in my Electrolux/Aerus machines.
I still haven't found anything that I like to use in all the others.
