Frequently Asked Questions
Q. Does the filter have a separate expiration date?
A. Since the filter is blended with other beneficial ingredients besides hot spring powder, it is recommended to use it immediately after opening and within three years from the manufacturing date if unopened.
Q. How long does one filter last?
A. For home use, it can be used for about 25 to 40 days (on average, one month), and for travel use, about 7 to 10 days.
Q. From which region's hot spring is it made?
A. This is a hot spring located in Yangpyeong, Gyeonggi-do, South Korea, and its hot spring ingredient has undergone a total of 13 clinical trials, is patented, and is registered as a cosmetic ingredient both domestically and internationally.
Q. Is it rich in minerals?
A. Yes, this hot spring water contains 3.99 PPM of sulfur, which ranks in the top 1% of sulfur content among domestic hot springs.
Q. I often drop the shower head. Is it durable?
A. There is no problem if it falls on the front or back, but please be careful as the connecting part may break if it is dropped on the side.
Q. Can it be used with other shower heads?
A. If you purchase only the hot spring filter, it is compatible with all shower heads thanks to its international standard specifications. However, when using a shower head with an on/off option, the internal pressure may cause separation, so we recommend using the dedicated Onsha shower head.
Q. The hot spring refill runs out too quickly.
A. If you insert the refill in the wrong direction, it will be used up much faster. Please check the guide and insert it in the correct direction.
Q. How is the hot spring filter different from other vitamin filters?
A. The hot spring filter is made by blending Onsen water, a unique cosmetic ingredient of SurLab, and has undergone multiple clinical trials. As the hot spring powder dissolves, it maximizes the effect of enjoying mineral-rich hot spring water at home with ease.
