Shark Anti Odour Cartridge 4PCS, Odor Neutralizer Replacement Cartridges for Shark Vacuum Cleaner HZ3000UKT, AZ3000UKT, NZ860UK, NZ860UKT, IZ400UKTSB, IZ400UKT, IZ400UK, IZ420UKT, Part No. 1541FC3000

These are fabulous, fit my shark perfect and smell beautiful.

Bought because the genuine shark ones were out of stock. Can’t even smell them on maximum setting

They came quickly - were easy to fit but I really didn't notice any sort of fragrance/freshness from these

As soon as I open the packet the remaining 3 are going to lose their scent as all.4 are packaged together

No smell or scent at all. Useless.

This set of 4 cartridges came in a sealed bag with each one also in a sealed bag within the outer one. Upon opening the outer one I got a strong scent which was pleasant. To keep them fresh I put them into a sandwich/freezer bag leaving each one in it's own bag. It fitted well to the cap however doesn't come with a clear marker like the originals so you have to fiddle around to get it lined up. In use, this is where it really was a let down. I simply couldn't smell the scent at all. As this is the whole point of the cartridge I find it hard to recommend at all. It's a shame as it fits and the initial odour is nice and strong.
