12 Pack Produce Saver Refills Kit for OXO GreenSaver Produce Keepers and Crisper Inserts, Keep Fruits Veg Fresh, Also Compatible with Bluapple Produce Freshness Saver Balls and other Produce Savers

So I am assuming these are not genuine Oxo fridge keeper filters, but they work and last as long.

Non sono gli originali ma non credo che ci sia differenza tra gli uni e gli altri.

Fit our OXO produce keeper perfectly. Good value so we can change them as recommended. Really seem to prolong the life of our produce.

These really do help keep produce stay fresh. I've been using this product for many years. Very happy with it.

I THINK it's working because it's keeping my cabbage more fresh than before but I'm not 100% sure that it is. It's very easy to use, since you just need to pop it in and slide the top on. I feel better using it but ... I wouldn't be able to tell you if it actually works.
