BioFresh keeps food fresh for up to 5 times longer:
- Lettuce stays crisp for up to 13 days – instead of just two.
- Pears remain juicy and sweet for up to 34 days longer.
- Goat’s cheese stays aromatic for up to 20 days – rather than just four.

Frequently asked questions about BioFresh
BioFresh is one of Liebherr’s freshness technologies. It is based on knowing the correct storage conditions for food. By developing a separate compartment with the ideal climate for each group of products, they stay fresh and edible for longer. Because the temperature in the vegetable drawer with BioFresh is 0°C, it can be described as a 0-degree zone in the fridge.
For longer storage and to preserve nutrients, the interplay of humidity and temperature has to be perfect. Each type of food – from fruit and vegetables to meat and dairy to fish and seafood – has its own requirements for ideal conditions. BioFresh's flexibly adjustable compartments provide these conditions, ensuring a longer shelf life. Get to know our other cooling technologies too, such as HydroBreeze and DuoCooling.
The BioFresh safes differ primarily in the humidity levels they store food at. While fruit and vegetables in the Fruit & Vegetable safe are kept at a high humidity level to retain as many vitamins and nutrients as possible without losing much water, dairy and meat products prefer a drier environment. In the Meat & Dairy safe, BioFresh technology keeps the humidity as low as possible.
Yes, as long as the BioFresh safe is set to a temperature of 0°C, fish can also be stored perfectly well in the 0-degree zone of the fridge. If you want to keep your fish even longer, you should opt for BioFresh Professional with the Fish & Seafood safe. In this climate zone, the temperature can be lowered to -2°C independently of the other compartments. This keeps fish and seafood fresh noticeably longer.
Unpackaged food stays good for several weeks with the BioFresh safe. Even cheese can be stored in this way for several months. BioFresh technology increases the shelf life of many foods compared to a fridge with a vegetable compartment without BioFresh. Take a look at our BioFresh fold-out card and find the exact shelf life for your favourite foods.
Yes, the fridge-freezers with BioFresh are equipped with either NoFrost in the top freezer or SmartFrost technology. You decide which of the technologies your appliance should come with. While SmartFrost means you have to defrost less often, NoFrost technology spares you the job entirely. Some of the BioFresh Side-by-Side fridges also have NoFrost in the freezer compartment.
Both BioFresh and EasyFresh technologies ensure ideal humidity levels in their climate zones. Both technologies use a tight seal to do this, which increases the humidity. The difference lies in the temperature: In the EasyFresh safe, the temperature is the same as in the rest of the fridge compartment. In the BioFresh safe, temperatures are close to 0 °C, which means the 0-degree compartment in the fridge offers you new options for setting independent temperature zones. Choose a fridge with a vegetable compartment that allows you to store your food individually.

1) Claims for food preservation are based on scientific studies which have been analysed and evaluated by Liebherr internal experts and checked by experts in the field of food preservation from the University of Applied Sciences Münster. The shelf-life data is based on ideal storage conditions and depends on the correct storage without interruptions to the cold chain from harvest or manufacturer to the BioFresh safe.
