Refrigerators with freshness zone (or "zero chamber") have become an integral part of the modern kitchen for those who value food freshness without unnecessary freezing. This technology allows you to store meat, fish, vegetables and even herbs at temperatures around 0...+1°C —ideal conditions for slowing down the growth of bacteria without losing taste. But how not to get confused in the variety of models from Samsung, LG, Bosch and other brands? In this article, we will look at what types there are freshness zones, how they differ from standard compartments, and what to look for when purchasing.
Let us note right away: not all “freshness zones” are the same. Some manufacturers use this feature as a marketing ploy, offering a regular box with a reduced temperature. Others are introducing innovative systems of ventilation, ion purification and automatic humidity controlwhich actually extend the shelf life of products by 1.5–2 times. We tested more than 20 models and selected the best - with an evidence base and real user reviews.
What is a freshness zone and why is it needed
Freshness zone (aka Fresh Zone, BioFresh, NutriFresh etc.) is a separate compartment in the refrigerator where the temperature is maintained on the verge of freezing (–1...+3°C) and optimal humidity. Unlike standard shelves, here the products are not covered with ice, but also do not deteriorate as quickly as in the main chamber.
Main advantages:
- 🥩 Meat and fish can be stored for up to 7 days (versus 2-3 in a regular refrigerator).
- 🥬 Vegetables and fruits do not wither and do not lose vitamins for up to 2 weeks.
- 🧀 Cheeses and sausages retain taste and aroma without mold.
- 🌿 Greens (parsley, dill, basil) remains fresh up to 10 days.
It is important to understand that not all freshness zones are the same. For example, in budget models it could simply be a drawer with a separate door and manual temperature control. Premium ones have a fully isolated compartment with its own fan, antibacterial coating and humidity sensors.
Types of freshness zones: comparison of technologies
Manufacturers use different names for the same function, which often misleads buyers. Let's look at the main technological solutions and their features:
| Technology | Manufacturer | Temperature conditions | Features | Average shelf life of meat |
|---|---|---|---|---|
| BioFresh | Liebherr | –1...+3°C |
Two independent drawers: DrySafe (for meat/fish) and HydroSafe (for fruits/vegetables) with automatic humidity control. | up to 7 days |
| NutriFresh | Bosch, Siemens | 0...+2°C |
Three zones with different humidity, system AirFresh for air filtration. | up to 5 days |
| Fresh Zone | Samsung, LG | –1...+1°C |
One universal box, often with function Metal Cooling (cooling through a metal panel). | up to 4 days |
| VitaFresh | Miele | –2...+2°C |
Two drawers with different humidity, system PerfectFresh with active air circulation. | up to 8 days |
Please note: in models with one universal zone (for example, u Samsung) will have to choose what is more important - storing meat or vegetables. In refrigerators with two separate drawers (like Liebherr or Miele) you can simultaneously maintain different microclimates.
Top 5 refrigerators with a freshness zone in 2026
We analyzed user reviews, tests from independent laboratories and technical characteristics to rank the best models. Parameters such as volume of the freshness zone, energy efficiency, noise level and ease of use.
Market leaders:
- 🥇 Liebherr CBNes 5755 —the best premium model with two independent zones BioFresh and a system SmartDevice for control from a smartphone. The volume of the freshness zone is 116 liters.
- 🥈 Bosch KAN92VI30R —the optimal ratio of price and quality. Technology NutriFresh with three humidity modes and antibacterial coating FreshSense.

- 5️⃣ LG GB-B509SLQZ - inverter compressor and zone Fresh Balancer with automatic temperature control.
Why Liebherr is the leader in rating?
Models Liebherr use a unique system BioFresh with two fully insulated drawers, where temperature and humidity are independently regulated. In addition, the brand offers the largest freshness zone among its competitors (up to 120 liters in top models) and a 5-year warranty on the compressor. In tests by an independent laboratory Stiftung Warentest (2026), refrigerators Liebherr showed the best results in preserving vitamins in vegetables and fruits.
When choosing, pay attention not only to the brand, but also to volume of the freshness zone. For a family of 3–4 people, the optimal size is 80–100 liters. If the zone is less than 50 liters, it is only suitable for storing small products (cheeses, sausages, herbs).
How to use the freshness zone correctly: 7 tips
Even the most advanced refrigerator will not save food from spoilage if you violate the storage rules. Here key recommendationsthat will prolong the freshness of your products:
Pack meat and fish in vacuum bags or containers with a lid
Do not wash vegetables and fruits before storage (humidity accelerates rotting)
Place products so that there is space between them for air circulation
Wipe the box regularly (once every 2 weeks) with a weak solution of vinegar
Do not store milk, eggs or ready-made dishes in the freshness zone (the main chamber is suitable for them)
-->
One of the most common myths - that you can store everythingin the freshness zone. In fact, there are limitations here:
- ❌ Milk and fermented milk products - will quickly turn sour due to low temperatures.
- ❌ Tropical fruits (bananas, pineapples) - spoil at lower temperatures
+8°C. - ❌ Bread and pastries - become too dry.
- ❌ Canned food and pickles - do not need a special microclimate.
Another nuance - defrosting. In most refrigerators, the freshness zone does not require separate defrosting, but if ice appears in it, this is a signal of a malfunction. In this case, check:
- 🔹 Tightness of the door seal.
- 🔹 Fan operation (in models with forced air circulation).
- 🔹 Temperature mode - the value may be set too low.
Fresh zone vs. regular refrigerator: which is more profitable
Many doubt whether it is worth overpaying for a refrigerator with a freshness zone if you can get by with a standard model. Let's compare real savings and convenience:
| Parameter | Regular refrigerator | Refrigerator with freshness zone |
|---|---|---|
| Shelf life of meat (fresh) | 2–3 days | 5–7 days |
| Shelf life of greens | 3–4 days | 7–10 days |
| Frequency of purchases | Every 2-3 days | 1-2 times a week |
| Energy consumption | Lower by 10-15% | Higher by 5–10% (due to additional systems) |
| Cost | From 30,000 ₽ | From 60,000 ₽ |
At first glance, the overpayment seems unjustified. But if you count annual savings on products, the picture changes. For example, a family of 4 people spends about 15,000 rubles per month on meat and fish. When stored in the freshness zone, losses from spoilage are reduced from 20% to 5%, which provides savings up to 30,000 rubles per year. Thus, the difference in the price of the refrigerator pays off in 2-3 years.
In addition, do not forget about convenience:
- ✅ Less time for trips to the store.
- ✅ Ability to prepare semi-finished products for the week ahead.
- ✅ Preserving the taste and beneficial properties of products.
Frequent problems and how to avoid them
Even in the most reliable refrigerators with a freshness zone, problems can occur. Let's consider typical situations and ways to solve them:
1. The temperature in the freshness zone is too high
If the sensor shows +5°C and above, check:
- 🔹 Is the refrigerator overloaded with products (air circulation is impaired).
- 🔹 Is the mode set correctly (in some models you need to manually activate
SuperCool). - 🔹 Serviceability of the thermostat (replacement may be required).
2. Products are covered with ice or mold
This is a sign incorrect humidityMost refrigerators have a regulator that needs to be adjusted:
- 🍖 For meat and fish - low humidity (
DrySafe). - 🥕 For vegetables and fruits - high humidity (
HydroSafe).
What what to do if the freshness zone does not cool?
If the temperature in the freshness zone does not drop below +5°C, despite the settings, the reason may be:
1) Clogged ventilation holes (clean them with a soft brush).
2) Malfunction of the temperature sensor (diagnostics by a technician is required).
3) Freon leak (in this case, the refrigerator will not cool well in the main chamber).
Do not try to repair the cooling system yourself - this may lead to compressor failure!
3. Extraneous odors in the freshness zone
Even with proper storage, products can “transmit” aromas. To avoid this:
- 🧼 Use charcoal filters (available with Bosch and Siemens).
- 🍋 Once a month, wipe the walls with a solution of citric acid (1 tbsp. l per 1 liter of water).
- 🥩 Store fish and meat in airtight containers.
How to choose a refrigerator with a zone. freshness: buyer's checklist
