What does Product filtering mean?

Product filtering is an e-shop feature that lets customers narrow down the offer by selected properties and find suitable goods faster. Products can be filtered by price, brand, size, color, availability, material, rating or other parameters typical for the category. Unlike regular sorting, which only changes the order of items, a filter temporarily hides unsuitable products and shows only those that meet the selected criteria. Well-designed filtering makes navigation easier, especially in a large assortment, shortens the path to the right product and can positively affect the user experience and the likelihood of completing a purchase.
