Frequently Asked Questions
How to use Delios
How can I use Delios? |
It's very simple. Fill Delios container with the source water and squeeze it. Please refer to How to use Delios for details and demonstration. |
| Can I use Delios filter with other bottles? Any examples? |
Yes, you can use Delios filters for various types of bottles. For example, Delios filters can be used with Platypus products, which some mountaineers and campers are doing. Although Delios filters are initially designed to fit on all types of PETE bottles manufactured in Japan, they are compatible with certain types of plastic bottles used for fizzy drinks and water when it comes to the UK and abroad. |
| Can I use the filter for beverages such as milk, juice and coffee? |
No. You are advised not to use Delios to filter beverages such as milk, fizzy drinks and coffee. Although it may take away taste, colour and impurities, its filter will be clogged unnecessarily. All filtration and purifying products on the market are designed to 'filter water' available in the nature, not to 'convert' drinks or other liquid forms into pure water. |
| I have heard that Delios cannot be used for the water where there are no fish. Is this true? |
Yes. Fish living in the water sources such as river and pond indicates that they are not contaminated by water-dissolved poisonous materials. On the other hand, water sources where there are no fish around may contain high level of acidity or poisonous materials. It is reasonable that we avoid using water sources which are obviously contaminated to our naked eyes. |
| What type of water can I use ? |
The water sources include river, rain, lake, pond, streaks, melted snow as well as water from swimming pool, toilet tank/bath tub and expired bottled water in PETE and tanks. The filter can remove germs, mold and other microbes which are difficult to detect even with an optical microscope. |
| Does Delios remove viruses or chemical substances? |
Delios cannot remove viruses if you consider it being just a single entity as they are too small to be trapped by the filter, despite its 0.2 micron pore size. Having said that, viruses cannot exist on their own and have to live with other substances. Therefore, Delios is theoretically able to remove viruses. Delios will not remove substances that have already been dissolved in the water. Water-dissolved substances include salt in the sea water and poisonous organic and chemical materials. It is ideal to avoid using highly dirty and contaminated water as much as possible. In case you need to use highly contaminated and dirty water from the beginning, it is recommendable that you use liquid iodine and other disinfectants jointly with Delios. This is not to say the filter performance of Delios is not effective without sterilization. |
| Travelling abroad, camping and other outdoor activities |
Travellers can take Super Delios with them when going to developing countries where the quality of water and ice cubes is not guaranteed. It is often hard to find safe drinking water in such countries unless you are staying at a major hotel that provides safe drinking water. Purchasing bottled water is expensive and it may not guarantee its authenticity. If you have Super Delios, you can drink safe water anytime. You can also use clean water to brush your teeth, rinse your eyes, and even clean your wounds should you suffer a sudden accident. Delios is a camper's favorite item and is recommended for outdoor activities, including hiking, camping, bicycling and fresh-water fishing. You can safely drink water from rivers, lakes or streams whenever you feel thirsty. If the water supply in the camping field runs out, Delios will prove you with safe drinking water.

About performance and filtering capacity
| Why do you recommend 200 litre filtering capacity for Super Delios while you also mentions filtering capacity of approximately 1,000 litre for the filter? |
We would like to clarify why different filtering capacities are mentioned. The filter can filter up to 1,000 litre of water but it will be expected to fall to 200 litre, where a strong squeeze for filtering highly murkier water is applied very frequently and intensively. In other words, the murkier and dirtier the water you use, the more quickly clogged the filter will become. Having said that, if you are an occasional camper or traveller, the filter will be usable for a quite long time, for example, for 2-3 summers, provided that you clean and store the filter after each use as explained in the instructions provided. |
Delios uses fibrous activated carbon. How does it differ from ordinary activated carbon?
|
Fibrous activated carbon is made of fine and thin fibers which are carbonised. Its absorption speed is much faster than ordinary activated carbons. We adopted the fibrous activated carbon to make the filter unit as compact and efficient as possible. |
| I am using a portable water filter which has no bacteria-removing filter. What is the difference between Delios and the one I own? |
Your product seems to require chlorine or iodine to disinfect the unfiltered water. Chlorine or iodine works differently. The filter design of Delios is one of the major features as shown in How Delios Works. Delios' high-performance fibrous activated carbon removes disagreeable odors in the first stage. Then, the hollow fiber filter completely removes disease-causing bacillus, bacteria, mold and contaminated materials from the source water. You can drink water from the river, as well as water in countries where the quality of water is poor. You can still use chlorine or iodine with Delios to be on the safe side if you are using very dirty water. |
I find that other bacteria-removing filter built-in water purification kits are heavy and bulky. How about Super Delios?
|
Some built-in filters are made of ceramic, making the whole unit heavy and expensive. Super Delios is very light and its total weight is 58g, which includes a hollow fiber filter and polyethylene container. It is very easy to carry. You can roll the container and keep in your pocket. Delios is popular among those who enjoy walking, hiking, camping over weekend or those who wants to take extra care from the tap water during their holiday or business trip in countries where the quality of water is not guaranteed. We want to offer a choice to you depending on your needs. For example, if you are not keen to do a survival type activity and to use a tough-guy style bottle, but you want to enjoy more casual weekend hiking, then Delios is your choice. Delios is easy to carry, so your children and grandparents can carry it easily. |
I am wondering how reliable Delios is.
|
Delios has been a popular product with its proven performances, practicability and hygienic and safety standards in Japan. Each Delios unit is inspected in compliance with stringent standards in Japan for the purposes of maintaining high quality and hygiene standards. In addition, due to the design of the screw-on filter, you can substitute most off-the-shelf PETE bottles or a Platypus bottle if you prefer, or if you need a larger container and do not require the pocketable features of the container that comes with the product. We are producing all parts of Delios in Japan under our eyes so that we can deliver quality assurance to you. |
| Delios is like a ketchup bottle, which makes me think that Delios is not a high quality product. Why did you use such design and container? |
This is a matter of practicability. We aimed to avoid making the product unnecessarily heavy and complicated to use. We prioritised high performance, reliability, ease of use and reasonable price. The fact that you cannot see the filtering elements inside the cap does not mean that Delios is not doing its job. Delios contains excellent filter unit, one of the best in the world. Super Delios' polyethylene container is strong, flexible and durable and allows you to roll or fold it to a pocketable size, without causing damage to the container. The container of Super Delios will continue to function safely even after being folded many hundreds of times. We have not received any reports about tearing or damaging in the past 10 years. The flexible container was, in fact, an important component of the original patented design for Super Delios.

| I have seen some reviews saying that Delios is a "must-have" item for emergency use. |
Natural disasters can happen anywhere anytime. Delios is an excellent addition to your home emergency kit thanks to its compact design. Experts in the water industry say that you need to get 9 liters of drinking water per person per 3 days in the event of an emergency. Super Delios will help you secure drinking water from various sources such as rain water, river, ponds, bathtubs and even water in swimming pools. Currently, Super Delios is being used in disaster struck zones such as South East Asia and has been used by NGO, charities, medical professionals and travel experts in Japan and abroad. |
Other issues
| What is the shelf life of both an unused and used Delios? |
Once used, you can wash the filter and store it in a dry place for future use. You are advised to use disinfection products when washing the filter. Unused Delios can be stored for more than 10 years! |
| About the price of Delios |
We believe that the price is very reasonable. Delios' filter requires careful inspection, which is costly, but we aim to keep the whole structure of the Delios very simple in order to keep the entire manufacturing cost as low as possible. Delios is one of the most reasonably priced and effective bacteria-removing portable water filtration kit in the world.
Even though it may not look "high quality", it actually works as advertised. |
