LG Vitamin Plus refrigerator: how does the technology work and is it worth overpaying?

Refrigerators LG Vitamin Plus are often found in advertising brochures and reviews, but what is actually hidden behind this marketing name? If you are faced with choosing a new technology and doubt whether the overpayment for a “vitamin” function is justified, this article will help you understand the details. We analyzed the manufacturer's patent documents, user reviews and independent tests to separate real benefits from advertising promises.

The technology Vitamin Plus is positioned as an innovative solution for maintaining the freshness of products due to a special filtration and air circulation system. However, not everyone knows that behind this is not magic, but very specific engineering solutions - from ultraviolet lamps to multi-layer activated carbon filters. In this article we will reveal the real mechanism of operation of the Vitamin Plus system, compare it with competitors (for example, Samsung Twin Cooling) and give practical recommendations for operation.

We will pay special attention to the questions that most often concern buyers: do products really stay fresh longer? Do I need to buy special containers for this technology? And why in some models LG this function is disabled after 3-5 years? The answers are below.

What is Vitamin Plus in LG refrigerators: technical explanation

Technology Vitamin Plus is a comprehensive solution that combines several systems:

• 🔹 Ultraviolet lamp — installed in the freshness zone (usually in the lower drawer for vegetables/fruits). It turns on automatically for 15-30 minutes every 6-8 hours, destroying up to 99.9% of bacteria and mold fungi on the surface of products.
• 🌬️ Multi-stage air filtration - includes a HEPA filter, a carbon filter and a photocatalytic element. The latter decomposes organic compounds (for example, ethylene, which accelerates the ripening of fruits) under the influence of UV radiation.
• 💨 Dynamic circulation —fans evenly distribute purified air throughout all compartments, preventing the formation of “dead zones” with stagnant air.

It is important to understand that Vitamin Plus is not one function, but combination of hardware and software solutions. For example, in models LG GB-B599SLQZ or LG GR-B429JVC the system is paired with an inverter compressor, which maintains a stable temperature without sudden changes. This is critical for preserving vitamins: with temperature fluctuations (for example, during defrosting), vitamin C in greens is lost 20-30% faster.

The manufacturer states that the technology extends the freshness of vegetables and fruits up to 14 days (versus 5-7 days in conventional refrigerators). However, independent tests show more modest results: on average, products remain marketable 30-40% longer. The difference is explained by storage conditions: if you put already spoiled tomatoes in the refrigerator, even Vitamin Plus will not save the situation.

How to distinguish real Vitamin Plus from a fake: original technology markers

Not all refrigerators LG with the inscription "Vitamin+" on the body are equipped with a full-fledged system. Here's how to check that you're paying for real technology and not marketing:

1. Presence of a UV lamp. In the original models, it is visible through the transparent lid in the vegetable drawer (for example, in the LG InstaView Door-in-Doorseries). The lamp should blink blue when the door is opened.
2. Filters with a replacement indicator. On the back wall of the refrigerator there should be a removable filter unit with a reset button (usually marked as Filter Reset). In fakes, the filters are not removable or there is no indication.
3. Special modes. The refrigerator menu should have an item Vitamin Fresh or Fresh Balancer (in models 2022 and newer). In older versions - Nano Fresh.

Beware of models with the prefix "Vitamin+" in the name, but without technical implementation. For example, in LG GA-B489YDQZ this function is available, but in LG GA-B429YVQA (despite the similar name) it is not. To avoid mistakes, check serial number on the LG website: the first 3 characters after the hyphen indicate the presence of technology (code VIT or FRS).

Comparison of Vitamin Plus with analogues: Samsung Twin Cooling, Bosch VitaFresh and others

The technology Vitamin Plus is not unique - each brand has its own solutions for renewal freshness. Let's consider the key differences:

The main advantage Vitamin Plus over competitors is active disinfection with a UV lamp. While Samsung Twin Cooling it simply separates the air flows between the refrigerator and freezer compartments, and Bosch VitaFresh regulates humidity, LG actually destroys germs. However, this also becomes. weak point: the UV lamp loses efficiency over time, and its replacement costs 3000-4000 rubles.

If maximum freshness of herbs and berries is important to you, Vitamin Plus is the best choice for storing meat or fish. more effective Panasonic NutriFresh with a vacuum zone. And if the budget is limited, Bosch VitaFresh offers 70% of the result for half the price.

Why does LG Vitamin Plus turn off after 5 years in some models?

In refrigerators before 2020, the UV lamp had limited resource (about 20,000 hours of operation). After this, the system automatically turned off, since further operation could lead to overheating. In new models (2021+), the lamp is replaceable, but its cost and installation cost 3500-5000 rubles.

Pros and cons of Vitamin Plus technology: an honest analysis

The advantages of the technology are obvious, but there are also hidden nuances that the manufacturer is silent about. Let's look at them point by point:

• ✅ Real. prolongation of freshness - tests confirm that lettuce, dill and berries remain fresh for 3-5 days longer than in conventional refrigerators. The effect is especially noticeable for leafy greens.
• ✅ Destruction of odors —the photocatalytic filter decomposes ethylene molecules (which are emitted by fruits) and ammonia (from meat/fish). This means that the aroma of onions will not be absorbed into the oil.
• ✅ Low noise level —system fans operate at a frequency below 40 dB, which quieter than most analogues.
• ❌ High cost of maintenance —filters need to be changed every 6 months (price ~2500₽ per set), and the UV lamp - every 3 years.
• ❌ Limited efficiency for meat —the technology works better with herbal products. Vacuum packaging is required for meat/fish.
• ❌ Dependency on electricity —when the lights are turned off, the system stops working and food spoils faster than in a conventional refrigerator (due to the lack of natural ventilation).

One one of the most controversial points - energy consumption. Refrigerators with Vitamin Plus belong to the class A+++, but in practice, energy consumption is 15-20% higher than that of models without this technology. This is due to the operation of the UV lamp and fans. For example, LG GB-B599SLQZ consumes ~380 kW/year, while a similar volume Samsung RB37J5240SA is ~320 kW/year.

How to properly operate a refrigerator with Vitamin Plus: 7 rules

Even The most advanced technology will not save products if storage rules are violated. Here's what you need to do:

1. Do not overload the vegetable drawer. The optimal load is 70% of the volume. If you put more, the UV lamp will not be able to process all the food evenly.
2. Wash the filters every 3 months. They can be washed under running water (no detergents!) and dried for 24 hours before installation. This will extend the life of the filters by 20-30%.
3. Do not store in the Vitamin Plus area:
   • 🥛 Dairy products (they do not need UV treatment)
   • 🍖 Raw meat/fish (requires a vacuum or temperature below 0°C)
   • 🍞 Bread (under the influence of UV it becomes stale faster)

Use original containers. The refrigerator comes with plastic boxes with micro-perforations (for example, LG Fresh Box). They allow UV rays to pass through, but retain moisture.

A mistake made by many users - disabling the Vitamin Plus function to save energy. This leads to filters becoming clogged and the lamp becoming coated. If you decide to turn off the system, do it through the menu (Settings → Modes → Vitamin Fresh → Off.), and not by pulling the plug from the socket. Otherwise, the calibration of the sensors may be lost.

Common problems and their solutions

Refrigerator owners LG Vitamin Plus face several common problems. Most of them can be solved without calling a specialist:

If after After reset, the lamp still does not work, check its power circuit. In models LG 2019-2023, the lamp is connected through a separate control unit (UV Control BoardIt can be replaced independently (cost ~1800₽), but a soldering iron and skills in working with electronics are required.

⚠️ Attention: If on the display refrigerator has an error code Er FF, this means a malfunction in the filtration system. Do not try to reset the error manually - this may lead to overheating of the lamp. Contact a service center to diagnose the filters.

Is it worth overpaying for Vitamin Plus: analysis of prices and alternatives

Refrigerators with Vitamin Plus cost 20-30% more than analogues without this technology. Let's figure out whether the overpayment is justified:

• 💰 Cost of the model: A refrigerator LG GB-B599SLQZ (with Vitamin Plus) costs ~120,000 rubles, and similar LG GA-B509YDQZ (without it) - ~90,000 RUR. The difference is 30,000 RUR.
• 📅 Payback period: If you spend ~15,000 RUR/month on products, the savings due to extended freshness will be ~1 500₽/month (according to Roskachestvo). Thus, the overpayment will pay off in 20 months.
• 🔧 Maintenance costs: Filters (~2500₽/year) + lamp replacement (~4000₽ every 3 years) = ~3500₽/year. payback period up to 2.5 years.

Alternative ways to prolong the freshness of products without Vitamin Plus:

• 🥬 Use containers with ethylene absorbers (for example, EggsNow or Bluesmart). Cost - from 500 rubles per piece.
• ❄️ Store vegetables in vacuum bags with air pumping (vacuumizer costs ~3000 rubles).
• 🧊 Place containers with soda or activated carbon in the refrigerator (absorb smells).

Conclusion: Vitamin Plus is profitableif you:

1. You buy a lot of fresh vegetables/fruits (the savings on extending the shelf life cover the overpayment).
2. Are you ready to spend time maintaining the system (cleaning filters, replacing lamps).
3. You are looking for a refrigerator that will last 7+ years (the technology pays off only with long-term use).

In all other cases, a model with a conventional system No Frost and proper storage organization is sufficient.

FAQ: Frequently asked questions about LG Vitamin Plus refrigerators

Is it possible to disable Vitamin Plus if it is not needed?

Yes, the function can be disabled through the menu: Settings → Modes → Vitamin Fresh → Off.However, please note that this will stop the freshness zone fans and the temperature in the vegetable drawer. may rise by 1-2°C. If you store perishable products there (for example, greens), it is better to leave the system on.

How often do you need to change the filters in Vitamin Plus?

Official LG recommendation - every 6 months. However, in practice, the period depends on the intensity of use:

• If the refrigerator is opened less than 10 times a day - once every 8-10 months.
• If a lot of meat/fish is stored - every 4 months.
• If an odor appears, replace immediately.

The indicator on the control panel flashes red when the filter is clogged.

Is the UV lamp harmful to food?

No, the lamp emits UV range Vitamin Plus emits UV range UVC (254 nm)which destroys bacteria, but does not penetrate deeper than 0.1 mm into products. This means that the vitamins inside, for example, an apple, remain intact, and only microbes on the surface are killed. For comparison, medical sterilizers use the same principle.

Is it possible to install Vitamin Plus in an old LG refrigerator?

No, this is impossible. The technology is integrated into the cooling system and control of the refrigerator. The maximum that can be done is to buy a separate UV sterilizer for products (for example, Xiaomi Viomi UV Sterilizer) and use it to process vegetables before storage.

Why do dairy products quickly spoil in a refrigerator with Vitamin Plus?

The technology is optimized for plant products. Dairy products (kefir, sour cream, cottage cheese) spoil due to two reasons:

1. The temperature in the zone Vitamin Plus is often higher than optimal for milk (+2...+4°C instead of +1...+2°C).
2. UV radiation accelerates the breakdown of lactose, which causes products to sour faster.

Solution: store dairy in the main chamber (on the middle shelf), and not in the vegetable drawer.
