A bunch of cilantro lasts about 4 days in its grocery store clamshell. The same bunch, stored correctly, lasts 2 to 3 weeks. The difference is the container. Stem-in-water towers extend tender herb life by triple, dry humidity boxes preserve hardier herbs without water management, and refrigerator-friendly footprints decide whether the tool actually gets used. After comparing the most popular herb storage containers on the market, these five stood out for stem support, humidity control, and refrigerator fit.

Prepara Herb Savor - Best Overall
The Prepara Herb Savor is the cilantro container worth buying for most kitchens. The design is right: a removable inner basket holds the stems suspended in a base reservoir of water, a tall clear dome traps humidity around the leaves, and the entire unit fits in either the refrigerator door or on a shelf. Cilantro and parsley routinely last 2 to 3 weeks rather than the 4 days a clamshell delivers.
The basket lifts out cleanly for water changes without disturbing the herb arrangement. Trade-off: the height (just under 10 inches) is too tall for some compact apartment refrigerators with short door bins. Best for any household that uses cilantro, parsley, or dill more than once a week, and for cooks tired of buying bunches that go bad before the second use.
Cuisinart CTC-100 Compact Tower - Best Compact
The Cuisinart CTC-100 Compact Tower is the apartment-friendly stem-in-water option. The lower-profile design (roughly 7 inches tall) fits standard refrigerator door bins and crisper drawers without forcing a reorganization, the removable basket and water reservoir work on the same principle as the Prepara, and the included measurement marks on the side help with consistent water-change refills.
The clear dome is shallower than the Prepara, so larger bunches need a slight trim before storage. Trade-off: the lower height means less air space around the leaves, which slightly reduces the humidity buffer for very fluffy herb bunches. Best for small refrigerators, dorm and apartment kitchens, and renters who do not want a tall counter-shelf-sized accessory in their fridge.
Tovolo Herb Keeper - Best Premium
The Tovolo Herb Keeper is the premium build in the segment. The dome is thicker BPA-free Tritan rather than standard polypropylene (which yellows over time), the silicone gasket at the dome base reduces humidity loss compared to friction-fit competitors, and the included stem trimming bracket on the basket helps cut stems to a consistent length on the first prep.
The shape footprint is also flatter and wider than the Prepara, which fits better on a shelf next to milk and juice jugs. Trade-off: the premium build comes with a premium price tag. Best for serious home cooks who use the herb keeper daily and want the cleanest-looking tool on a shared refrigerator shelf, and for anyone who has burned through one cheap herb keeper and wants the upgrade.
Norpro Herb Keeper - Best Budget
The Norpro Herb Keeper delivers the same stem-in-water principle at the lowest sustainable price in the segment. The polypropylene base and dome are thinner than the premium Tovolo, the basket is a simpler insert, and there is no integrated stem trimmer. But the core function (stems suspended in water under a humidity dome) works identically and extends cilantro life to 2 to 3 weeks.
Norpro sells through both supermarkets and online retailers, so replacement and emergency availability are easier than direct-to-consumer brands. Trade-off: the dome scratches more easily than Tritan and may yellow over a year or two of heavy use. Best for first-time herb keeper buyers testing the format, and for households where the herb keeper takes hard use (kids, frequent transport, dishwasher cycles).
Container Store Multipurpose - Best Mixed Herbs
The Container Store Multipurpose container is the right tool for mixed-herb households. The humidity-box format (sealed clear container with a moisture-regulating insert) preserves hardier herbs like rosemary, thyme, sage, and mint without water management. It also stores berries, salad greens, and cut vegetables, which makes it the most-used container in the fridge rather than a single-purpose tool.
The shape stacks cleanly with other Container Store food storage products. Trade-off: the humidity-box format does not extend cilantro and parsley life as long as a stem-in-water tower. Best for hardier herb users (rosemary, thyme, sage), for households that buy more salad greens and berries than cilantro, and for buyers who prefer one multifunctional container over a single-purpose tool.
How to choose an herb storage container
Match container to herb type. Tender herbs (cilantro, parsley, basil, dill, mint) need stem-in-water towers. Hardier herbs (rosemary, thyme, sage) do fine in humidity boxes.
Check refrigerator fit. Measure your door bin and crisper drawer before buying. A 10 inch tall Prepara does not fit every fridge.
Trim stems on first prep. Trim a quarter inch off each stem with kitchen scissors before placing in water, the same as with cut flowers. This roughly doubles storage life.
Change water every 3 to 4 days. Cloudy or smelly water means the herbs are about to spoil. A fast refresh keeps the bunch going.

Frequently asked questions
Why does cilantro go bad so quickly in the fridge?+
Cilantro is a tender herb with high water content in soft stems and delicate leaves. Standard refrigerator drawer storage exposes the herb to cold dry air that pulls moisture out, while the plastic clamshell from the grocery store traps ethylene gas that accelerates wilting. The bunch usually slumps within 4 days. A purpose-built herb container either stores the stems in water (mimicking a vase) or holds humidity around the bunch (mimicking a refrigerator crisper drawer at much higher humidity).
Stems in water versus dry humidity container?+
Stems in water (the Prepara, Cuisinart, and Tovolo style) is the longest-lasting method for tender herbs: cilantro, parsley, basil, dill, and mint. Properly used it gives 2 to 3 weeks of freshness. Dry humidity containers work for hardier herbs like rosemary, thyme, and sage where stem-in-water adds no benefit. For a mixed-herb household, owning one stem-in-water tower and one dry container covers everything. The stem-in-water tower is the right single purchase if you only buy one.
How often should I change the water?+
Every 3 to 4 days, or anytime the water turns cloudy. Fresh cool water from the tap is sufficient (no filtering needed unless your tap water is very hard). When changing, also trim a quarter inch off the bottom of each stem with kitchen scissors, the same way you would trim flower stems in a vase. This exposes fresh tissue that draws water more efficiently. Most stem-in-water containers also benefit from a quick rinse of the base reservoir during each change to prevent algae growth.
Should I wash herbs before storing them?+
No, store them dry and wash just before use. Wet leaves bruise quickly and develop dark slimy spots within a day or two. The exception is store-bought herbs visibly contaminated with grit or insects; those should be rinsed quickly under cool water, spun very dry in a salad spinner, and then placed in the container. Even with a quick wash, dry the leaves thoroughly before storage. Excess water on the leaves (as opposed to inside the stem-in-water reservoir) is the fastest path to early spoilage.
Can I use a glass jar with water instead of a dedicated herb keeper?+
Yes, and it works well as long as you also tent a plastic bag loosely over the top of the bunch. The bag traps humidity around the leaves while the stems drink from the water below, replicating the dome-and-reservoir design of dedicated herb keepers. The advantage of dedicated keepers is the integrated dome (no fiddling with bags), the trim-to-fit basket for proper stem-water contact, and the refrigerator-shelf-friendly footprint. For a frequent cilantro user, the dedicated tool is worth the spend.
