About Us

Sierra Mango, s.r.o. is a family business based in Bratislava, Slovakia. We started working in the B2B business of water filtration and hospitality in 2022, offering full systems of filtered, cooled, carbonated, and still water to restaurants, coffee shops, hotels, and private companies in Slovakia.

In 2025 we expanded across the EU and began selling directly to B2C customers interested in inline LED UV-C water filters. Sierra Mango, s.r.o. is a non-exclusive authorized European distributor for manufacturer Shenzhen Hechuang Technology Co., Ltd., under a signed distribution and trademark authorization agreement, and provides sales and after-sales support for their Innest™ product line across the EU.

All products are shipped from our own warehouse just outside Bratislava, Slovakia.

Innest™ is a registered trademark of Shenzhen Hechuang Technology Co., Ltd., used by Sierra Mango, s.r.o. under written authorization from the trademark holder.
