Detailed view of reference project
In the detailed view of the reference project on twala-wasserfilter.de, we developed a focused, conversion-oriented online shop for TWaLa® brand replacement filters for reverse osmosis and drinking water systems. The product range covers sediment pre-filters, activated carbon block and granulate filters, RO membranes and complete under-sink systems — all built around the universal 10″ standard. The shop is aimed at private households and trade customers who need lab-tested replacement filters at a fair price and want to be certain the parts fit their existing system. Thanks to a clear category structure, an interactive filter finder and free DHL shipping within Germany, visitors find the right filter set in a matter of clicks and can order it directly online.

Project overview
Our services
Twala-wasserfilter.de is a WordPress and WooCommerce based e-commerce platform with a custom-developed theme, fully responsive and optimised for fast loading times on mobile devices. It integrates established payment methods such as PayPal, Amazon Pay, credit card and advance payment, together with customer account management for orders, addresses and repeat purchases.
A central element is the filter finder, which guides customers to the products that fit their system and noticeably reduces incorrect orders and support requests. This is complemented by an editorial advice section (Ratgeber) that explains replacement intervals and filter stages — content that builds trust and pays into organic visibility at the same time.
The shop uses SSL encryption, GDPR-compliant consent management and follows SEO best practices in structure, metadata and product data. The flexible architecture makes it easy to extend the assortment, add new product categories and scale the business as it grows.
