EcoLoc in short

EcoLoc with PureFize functionality is an innovative solution designed to extend the shelf life of your food. It utilizes a unique UV light to slow down the natural process of food spoilage. When you store vegetables, fruits, bread, or meats using EcoLoc, the UV light inhibits the growth of certain microorganisms and enzymes that cause food to deteriorate.

What you get when you buy a starter kit

When you purchase the EcoLoc starter kit, you receive a complete package, including
one EcoLoc device with PureFize functionality, three plastic containers (1.0 l) and three EcoLoc lids that the device docks into.

Use the USB-C cable in the kit to charge your EcoLoc device.

Should you wish to expand your EcoLoc collection, additional lids can be purchased separately. Additional containers can be bought at

How do I use EcoLoc?

  1. Start by adding your desired food items to the food container. Make sure no to top the container so that the UV light can cover a wider area.
  2. Place the EcoLoc lid on top of the container, but do not snap it closed to lock it.
  3. Place the EcoLoc device in the designated area on top of the lid.
  4. Press the On button to activate EcoLoc’s PureFize functionality.
  5. Wait until the blue light stops flashing.
  6. Remove the EcoLoc device, snap the lid closed to lock it, and place the container in the refrigerator.

Voilà! Your food is now fresher and will stay that way for longer. If you want your food to last even longer, give it an extra burst.

How do I charge my EcoLoc device?

The EcoLoc device is charged through a standard USB-C cable. Connect your EcoLoc device to any compatible USB power source, such as a computer or a USB wall adapter, for efficient and reliable charging.

How long can I use the device once fully charged?

The EcoLoc device operates on batteries with minimal energy consumption. It employs a 2.6Ah battery, allowing the unit to run at least 20 cycles without recharging.

Who is PureFize?

The company was established in 2000 to pioneer more sustainable lighting solutions. Following a significant breakthrough in the broadband UV spectrum, the company shifted its entire focus towards creating intelligent solutions to enhance hygiene, implement high-level disinfection, and improve processes through PureFize technology. The company is headquartered in Uppsala, Sweden.

What is PureFize functionality?

PureFize is a unique technology that lies at the heart of EcoLoc’s food preservation capabilities. By harnessing the power of broadband UV light, PureFize eliminates the microorganisms responsible for food decay. Unlike traditional UV light systems that target specific wavelengths, PureFize utilizes a broad spectrum (250-350 nm) that effectively eradicates a wide range of microorganisms.

With PureFize, you can ensure that your food remains in optimal condition for extended periods, whether stored in the refrigerator or at room temperature.

What is broadband UV light?

Broadband UV light, as produced by PureFize, encompasses all three intervals of UV light: UV-A, UV-B, and UV-C. The uniqueness of PureFize lies in its comprehensive spectrum and ability to generate and harness the combined power of these three UV intervals. This combination has been found to offer advantages in effectively eliminating microorganisms and extending the shelf life of food.

In contrast, other light sources that emit UV light typically generate only one of the UV intervals: UV-A, UV-B, or UV-C. However, PureFize stands out as it utilizes a single light source capable of simultaneously producing all three UV intervals. This characteristic sets PureFize apart from other UV light sources and underscores its uniqueness in the market.

How does PureFize work?

UV light generated by PureFize technology is germicidal. Consequently, it eradicates contaminants (microorganisms) that break down food. These contaminants reside on the surface and are acquired through contact and exposure from production to your kitchen. In essence, by eliminating microorganisms that contribute to food breakdown, PureFize extends the lifespan of the food. Using vinegar can achieve a similar effect, but PureFize offers far greater convenience than washing all fruits and vegetables in a vinegar solution.

How much longer will my food hold with PureFize functionality?

The freshness and longevity of food primarily depend on the quality and condition of the food itself. However, with PureFize functionality, you can significantly extend the shelf life of your food compared to not using it.

When using EcoLoc with PureFize functionality, food preservation is further enhanced when stored in the refrigerator. It’s important to note that certain foods, such as tomatoes, may have improved taste when not chilled. PureFize functionality offers the advantage of prolonging the life of foods you prefer to enjoy at room temperature. On the other hand, if your priority is optimal preservation, we recommend utilizing both PureFize functionality and refrigeration together.

Is the food at the bottom of the food container equally treated?

The food at the bottom is not subjected to the same degree of PureFize light exposure as the food on the top, so the treatment will not be entirely uniform. However, both the microorganisms present on exposed food and those within the air inside the food container are reduced, contributing to improved shelf life.

Naturally, if the entire contents were fully exposed, the results would be more comprehensive. Nevertheless, if the container is opened to rearrange the contents – either by hand or using utensils – this would introduce new exposure to microorganisms.

However, if the contents are gently shifted without opening the container and additional cycles are run, the effect might be enhanced. We also advise initiating a cycle on an empty container before introducing food items. This precaution guarantees that the container’s interior is thoroughly clean and ready for use.

Can I use PureFize too frequently?

No, the dose generated by EcoLoc is insufficient to cause any alteration in taste or texture. Repeated cycles might even enhance the result.

What happens if I interrupt the session prematurely or remove the lid?

The EcoLoc device will halt automatically when removed during a session. If the session is not completed, the device will not have had the opportunity to eliminate as many microorganisms as it would during a full session, potentially resulting in a less optimal outcome.

If you remove the lid, the food is susceptible to being exposed to new microorganisms that can potentially shorten the lifetime. We recommend running a new session if the lid is removed for the best output.

Is PureFize safe to use?

The amount of UV light generated by PureFize is minimal and optimized for the food container environment. When used as instructed, PureFize is considered entirely safe. The low intensity of the light, combined with built-in safety features, ensures that users can feel confident in using the product.

In the unlikely event that the safety feature is overridden, either accidentally or deliberately, the dose of UV light remains very small. To experience symptoms equivalent to sunburn or potential consequences, one must be repeatedly and closely exposed to UV light for an extended period.

However, it’s important to note that direct and prolonged exposure to powerful UV light sources can be harmful. Therefore, it is crucial to exercise caution when dealing with such light sources.

Regarding the safety regulations for individuals working with UV light daily, the EU directive recommends a daily exposure limit of 30 J/m2. To put this into perspective, this is equivalent to:

Please note that when using PureFize according to the instructions, you will not be exposed to any light at all. The following information will provide further context:

UV light is a naturally generated light emitted by the sun. It is widely recognized that prolonged sun exposure without sunscreen or for extended periods can be harmful. Repeated sunburns significantly increase the risk of developing skin cancer, particularly melanoma.

Due to its higher intensity, only a small amount of light is required to eliminate microorganisms, which effectively benefits safety.

Your PureFize device includes a built-in safety feature that ensures the lights can only be activated when the device is correctly placed on the lid. As soon as you remove it, the lights will automatically shut off.

If the safety function is overridden, there is no need to panic. The table above can be used to estimate your exposure and compare it to the time spent in the sun.

Are there other methods to preserve food?

Food waste is a substantial and intricate issue that spans the entire value chain, from farm to fork. Therefore, there is no single solution to addressing food waste reduction.

At EcoLoc, we focus on developing a solution for convenient household use, as over half (+50%) of all food waste occurs within homes. Enormous amounts of energy and water are expended to bring food to the dining table.

Numerous methods exist for extending the shelf life of food, some more intricate than others. Essential factors include planning your purchases and maintaining order within your refrigerator and freezer. Additionally, not knowing how to repurpose leftovers is often a significant problem leading to food wastage. To address this, we have provided helpful links on our website to offer recommendations for utilizing leftover food effectively.

We aim to contribute to the reduction of food waste. Together, we face the challenge of decreasing food waste by 50% by 2030, in accordance with the UN Sustainable Development Goal 12.3. Consequently, we embrace all approaches that contribute to this goal and align with your lifestyle.

Here are a couple of alternative methods:

Vacuum preservation
Vacuum systems can be employed to preserve foods. The concept involves removing as much air as possible from the container, thereby reducing content oxidation. In external studies and our own laboratory tests, we have observed that many vacuum systems merely decrease air volume. This yields a limited effect. However, vacuum systems are particularly effective for marinating foods before cooking. If you want to use vacuum systems for food preservation, investing in a high-quality system that can genuinely achieve a strong vacuum is crucial.

Vinegar solution for berries
Another method involves rinsing berries in a solution of three parts water and one part vinegar. This practice helps them remain fresh for longer – if you thoroughly dry them after washing them and store them in a plastic container lined with paper towels.
