Q: How long does the sterilization process take?
A: Only 4 minutes.

Q: Can I take the LUMISAN smart bottle on holiday?
A: Yes, great idea! The LUMISAN smart bottle is also flight-proof, as long as you put it in your hand luggage. Our smart functions work as a result of the lithium battery in the cup cover. Lithium batteries are not allowed to be transported in your checked bag, therefor you need to take it with you in your carry-on. Make sure you empty the LUMISAN smart bottle beforehand because liquids, except for small 100ml flasks, are not allowed in your hand luggage.

Q: Is the LUMISAN smart bottle safe?
A: Yes, the LUMISAN smart bottle has been tested and is certified for the EU market. Please read the manual carefully before first use.

Q: What kind of drinks can I put in the LUMISAN smart bottle besides water?
A: You can use it for water and tea. We do not recommend putting coffee in the bottle, simply because it will be quite hard to avoid stains and a coffee smell in your LUMISAN smart bottle.

Please do not put dry ice, carbonated drinks and dairy products in the bottle for your safety.

Q: Can I put alkaline water in the LUMISAN smart bottle?

Q: I like infused water, such as water with blueberries, is that possible?
A: Yes, you can put fruits in your LUMISAN smart bottle to improve the taste of your water. However, we would like to warn you that the UV-C Light Technology will not be as effective since your fruit will prohibit the light from getting in every single corner of your flask.

Look at it as if the UV-C LED Light were the sun. Your body leaves a shadow wherever you go. That way your body prevents the sun from shining where your shadow lies. In this case the fruit would be your body and it prevents the UV-C Light Technology from shining and sterilizing at certain places.

Q: Is the LUMISAN smart bottle meant for cold or hot drinks?
A: Both! The insulation function is excellent. Drinks between 40°C and 55°C will stay warm up to 24 (!) hours. Cold drinks below 10°C stay cold for 6 hours. For more information, check out the product information here.

Q: Does the LUMISAN smart bottle get rid of heavy metals and/or fluoride?
A: No, it inactivates up to 99,99% of bacteria and viruses via UV-C Light Technology, but it does not contain a filter to remove heavy metals, nor fluoride.

For this reason, we do not recommend filling your LUMISAN smart bottle with water during a hike for example. The environment is severely polluted by heavy metals so even in natural waters they are present. There are many toxic heavy metals, even in low concentrations, so we do not encourage drinking polluted water.

Q: Do I need to clean the LUMISAN smart bottle or is it self-cleaning?
A: The LUMISAN smart bottle gets rid of germs but still needs to be cleaned. Why? Because a self-cleaning smart bottle sterilizes your drink, not the bottle itself. It is technically impossible to get rid of germs f.e. on the outside of the bottle without your help. Cleaning your LUMISAN smart bottle is therefor highly important.

The way this bottle needs to be cleaned, can differ from other bottles. Please read the instructions below carefully.

The LUMISAN smart bottle cannot be placed it in the dishwasher or dish dryer. The bottle is equiped with a battery and a LED UV-C light, which makes it impossible (and dangerous) to put it in the machines mentioned earlier.

However, it is important to eliminate germs on the bottle, especially on places where the UV-C light doesn't shine. Clean the cup cover with a slightly damp cloth or the small dish brush included in the packaging. Afterwards rub the cup cover with a dry cloth. Wash the cup itself by hand with a dish brush.

Q: Is the LUMISAN smart bottle BPA free?
A: Yes! The LUMISAN smart bottle does not contain BPA.

BPA stands for bisphenol A. Did you know that BPA is an industrial chemical that has been used to make plastics and resins? Many water bottles still contain BPA! You do not want BPA near your water. Research has shown that BPA can seep into beverages from water bottles that are made with BPA. Exposure to BPA may lead to health effects on the brain and prostate gland of fetuses, infants and children. It can also affect children’s behavior and other research even suggests a possible link between BPA and increased blood pressure.

Q: Which materials were used for the LUMISAN smart bottle?

Inner pipe and body outer pipe: 304 stainless steel (healthy and environmentally friendly material!)
Cover: ABS (acrylonitrile/butadiene/styrene copolymer 15e1)
Plug: ABS + PC (polycarbonate/polyacrylonitrile alloy plastic AC2300)
Sealing ring: silica gel

Q: How large is the LUMISAN smart bottle?
Size: 64x64x223mm
Net weight: 266g
Capacity: 450ml which equals about 2 glasses of water or 3 cups of tea.

Q: How many refills do I need a day to stay healthy?
A: Experts recommend to drink at least 1,5 liter water a day. This means you would have to drink only 3 and 1/3 LUMISAN smart bottles filled with water a day.

The LUMISAN smart bottle helps you to drink more water to hit at least one of your health goals a day! Try the drink reminder function to stay on track.
