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 when we started offering full systems of filtered, cooled, carbonated or still water to restaurants, coffee shops, hotels and private companies in Slovakia.

In 2025 we expanded into the entire EU and also started selling to B2C customers who are interested in inline LED UV-C water filters. We are Authorized European distributor for Shenzhen Hechuang Technology Co., Ltd. offering sales and after-sales support.

All products are shipped out of our local warehouse located just outside of Bratislava, Slovakia.
