Perfect for my Miele Leo canister. This replacement Hepa filter looks almost exactly like the original and fits in the filter slot just like the original. The fit and finish is just as good as the original filter. Only the name "Miele" is missing. Please note that other standard filters may not "snap in" and therefore allow air to escape around the case. I vacuumed this filter for 2-3 hours and in my admittedly unscientific tests I find it works very well. The activated carbon layer (?) eliminated stubborn odors from my vacuum cleaner.
