SCOTT PROFESSIONAL 91067 Continuous Air Freshener Refill, Citrus, 48mL Ca

The smell of these things is amazing. We bought it after our building used them in the common areas, and no other freshner we had used compared. Our first one lasted around a month and a half - but I had the "genius" idea to put it next to the a/c. The cold air will make these damp, and I think affected the lifetime as well. They don't really come with instructions; like many others, i found the link in youtube thanks to a helpful person here in the amazon comments. These are my instructions: grab one of them, and remove the plastic protector that is around the base press the bottom into the top - cover the gap that removing the plastic protector left. it will click, and it will require some force rotate? i guess. it doesn't click or anything, but i rotated it a few times for good luck... put it on the base if you want. I honestly think I didn't need the base, since i just put it on top of a table, I don't hang it or similar - at least it was cheap... Another tip: When you active them, you let the liquid wet the thin cotton walls the canister has. Notice that when they are new, they have a lot of liquid inside them. When you need to replace, the liquid is gone.

Toujours une bonne odeur

This is a great concentrated air freshener with a nice scent! especially if you don't want to deal with the overspray of metered mist air fresheners. It does require their special dispenser & the cartridges are a little pricey, but worth it to not have the overspray.

This product Scott 91067 continuous Air Freshener has no fragrance or feelings that you installed an item to get some freshness. Total wastage of your hard earned money.I spent $122 on this product plus I spent $30 on dispensers,gave a $0 value addition to my property.

I replaced a battery operated misting unit with t CELLS AND WAS VERY SATISFIED
