The Bosch FarmFresh System is the name our model pages use for a group of freshness features in some 800 Series French door refrigerators. The page for the B21CL81SNS says it combines four technologies: VitaFreshPro for precision humidity and temperature, FreshProtect for ethylene absorption, MultiAirFlow for even cooling and an AirFresh Filter for odor management. The practical tips are simple: give the air room to move, keep the produce drawer for produce, store ethylene-sensitive items away from ripening fruit and keep the door seals clean so the system can do its job.
What is the Bosch FarmFresh System?
It is a label for a set of features, not one part you can point to. On our model pages it appears on 800 Series French door refrigerators, for example the B21CL81SNS, the B36CL80SNS, the Benchmark B36CL80ENS, the 33-inch B33CT80SNS, the full-depth B36FD80SNS and the 30-inch B21CT80SNS. The pages describe it in different words: the B36CL80SNS page says it combines four technologies to maintain optimal freshness conditions, the B36FD80SNS page says it combines four freshness technologies, and the B21CL81SNS page lists them by name.
Some of our model pages also claim that produce stays fresh “up to 3x longer”. That is a claim on the page, and we have not measured it, so treat it as a best case. How long your strawberries last depends on how ripe they were when you bought them.
Where should you store produce in a FarmFresh refrigerator?
Use the drawer the system is built around. Our pages tie the precision humidity and temperature control to the VitaFreshPro drawer, so that is where fruit, vegetables and herbs belong, not the door bins and not the top shelf. Our explainer on how Bosch VitaFreshPro works goes through that drawer in more detail.
How to set the drawer on your model, and whether you can change anything, is in the owner’s manual. Do not assume that a control you remember from another refrigerator does the same thing here.
Which produce should you keep apart?
This part is common produce knowledge, not something specific to Bosch. Some fruit, such as apples, bananas, tomatoes and avocados, gives off ethylene gas as it ripens, and that gas speeds the spoiling of sensitive produce such as leafy greens, broccoli and cucumbers. FreshProtect is described as absorbing ethylene, which helps, but it is easier on any system if you do not pile the main ethylene producers right against the greens.
Keep ripe fruit in one place and sensitive vegetables in another, or put the sensitive ones in a closed container. If your drawer is divided, use the divider. A drawer that is too crowded also works against the system, because the air cannot move between the pieces.
What should you do before putting produce away?
Most produce keeps better if it goes into the refrigerator dry. Moisture left on leaves and berries encourages mold, so dry produce gently before it goes in the drawer, and wash it shortly before you eat it. Remove rubber bands and tight ties that bruise stems. Take out anything that is already bruised or soft, because one bad piece can spoil the pieces beside it.
Use clean, dry containers and keep cut produce covered. If your family cooks a lot with herbs, a loose bag or a container with a little air in it often works better than a sealed one, but follow your manual if it says how to use the drawer.
How does MultiAirFlow change how you load the shelves?
MultiAirFlow is described as circulating cold air for even cooling. Our MultiAirFlow explainer covers the idea. The tip that follows from it is not to block the airflow. Leave a gap between food and the back wall, do not cover the shelves with foil or trays that close off the air path and do not pack the compartment solid. A refrigerator that is stuffed full cools unevenly.
Put the items that need the coldest air, such as raw meat and dairy, where your manual recommends, and keep drinks and condiments in the door. Our Bosch refrigerator organization tips have more on layout, and the temperature settings guide explains how to set the compartment temperature.
How do you keep the system working over time?
Keep the door seals clean, because a gasket that does not seal lets warm air in and that works against every freshness feature. Wipe the gaskets with warm water and mild soap. Keep the drawer clean too: take out the produce, wipe the drawer with a mild soap solution, dry it and put it back. Check the manual for how and when to replace the AirFresh Filter, since the page names it but gives no replacement interval, and we will not invent one.
If you have a water filter, replace it on time; our guide to replacing the Bosch refrigerator water filter explains how. For a regular check of the whole refrigerator, the annual Bosch refrigerator maintenance checklist is a good list.
When is it a repair, not a tip?
If produce freezes in the drawer, if the compartment is warm, if you see ice build up on the back wall or if there is water on the floor, a tip will not help. Check first that the door closes fully and that nothing blocks the vents, then see our guides on a refrigerator that is not cooling and on frost buildup. Do not remove back panels or touch the cooling system. If water reaches an outlet or the cord, switch off the breaker at the panel while standing on a dry floor, and do not pull the plug out of a wet outlet.
