Quick verdict
Choose the Small GreenSaver if you buy modest herb bunches and want to use less refrigerator space. Choose the Large for longer stems or a bunch that would crowd the smaller basket. Skip both if your existing herb-storage routine works and you use the herbs promptly; this is a storage-format purchase, not a guaranteed number of extra fresh days.
Research-based buying guide. We have not tested these products hands-on. Specifications and care come from the linked manufacturer documentation; recommendations are our editorial judgment.
Which option fits your routine?
| Choice | Choose it for | Tradeoff |
|---|---|---|
| Small | Shorter stems and modest bunches | Less usable room around leaves |
| Large | Longer stems and bulkier bunches | More shelf or door-bin space |
| Existing suitable storage | Herbs you already keep and use successfully | May lack a removable basket |
Both sizes use the same basic idea
OXO describes a basket that supports herbs away from the outer container walls, handles for removal, and a hinged opening for access. The design combines airflow, controlled humidity and water in the base. Small and Large are two sizes of this herb-storage format, not different powered preservation systems.
That matters when comparing prices: a higher price for the larger keeper mainly buys room. It does not establish a longer shelf life, stronger performance or less need to check the contents. We have not run a controlled freshness comparison between the sizes.
Compare the physical size with your actual bunch
OXO lists the Small at 3.8 × 5.6 × 7.2 inches and the Large at 4.85 × 6.5 × 9 inches. These are overall dimensions, not guaranteed internal clearance for stems and leaves. The basket and lid occupy some of the space.
Look at the herbs you usually buy before choosing. A small wrapped supermarket portion and a long, leafy bunch need different arrangements. Leave enough room to load and remove the herbs without forcing them into a compressed shape simply to make the container close.
Fridge-door fit is a measurement, not a feature badge
OXO says the shape fits many refrigerator doors, but door bins differ in depth, lip height and spacing. Measure the narrowest usable area and the clearance above it. Also check that closing the door will not make the container strike a shelf inside.
A quick cardboard footprint can help you picture the space before spending. If the larger keeper displaces everyday drinks or must lie in an awkward position, a smaller container or an existing storage method may be easier to use. A tidy-looking product should not make the rest of the fridge harder to access.
The container still needs a routine
Follow the supplied directions for the base water, basket and cleaning. Inspect the contents regularly and use herb-appropriate storage guidance rather than assuming one arrangement suits every variety or every starting condition.
A keeper cannot restore already deteriorating herbs or compensate for buying much more than you use. If waste is the concern, start by noting which bunches you actually finish. Changing purchase quantity or planning another meal can be a more useful first step than buying a larger box.
Do not buy carbon filters automatically
The GreenSaver family contains other produce-storage products and filter accessories. A matching family name is not proof that a particular filter is required for these herb keepers. Buy only accessories specified for the exact model you receive.
Likewise, regional listings may use Small/Large, quarts or litres in their titles. Confirm the model numbers and physical dimensions: OXO identifies these herb-keeper sizes as 11212200 and 11212300. Do not substitute the capacity of a different GreenSaver produce container.
Who should buy—and our verdict
Buy Small when it fits the usual bunch without crowding and saves meaningful fridge space. Upgrade to Large when the extra stem and leaf room solves a recurring fit problem. Skip both if a working existing method already keeps the herbs accessible until you use them.
Our recommendation is to choose the smallest size that comfortably fits the herbs you actually buy. Do not pay for spare capacity or an unsupported shelf-life promise. The useful improvement is easier storage and access; the amount of food waste avoided depends on your routine.
Buying in the United States or Canada
Use the country button that matches where you shop. Compare the exact model, included parts, seller, delivered cost and return terms; marketplace offers can differ between the two countries. Check regional manufacturer support before relying on a guarantee for an imported item. We do not quote fixed Amazon prices or promise delivery to every address.
