I use my Smell Away SA1 to eliminate cooking smells. I generally turn it on in the kitchen while I'm cooking and then leave it on for about 10 minutes afterwards, while we're eating in another room. (Occasionally I use it in the living room too, if I forgot to turn it on while I was cooking or there's a lingering smell when we come back into the house).
The unit works really well when you leave it on for 10 minutes or so and are not tempted to turn it off too quickly. Give it time and it will get rid of the smell. I looked at the energy usage on my smart meter and the energy usage it's super-low :-) so I just don't worry about it being on.
The living room is attached to the kitchen so the unit stops the living room smelling of cooking (which we hate), so it's a great addition to the house.
