Water Filters

A water filter in professional equipment protects its internal systems from limescale deposits, mechanical impurities and chemical compounds in water that degrade performance and damage heating elements, pumps and piping. A worn or clogged filter reduces water flow, increases equipment strain and allows impurities to enter the system. Timely filter replacement is the most affordable investment in equipment longevity. BHS offers water filters to HoReCa businesses across Europe.

Types and applications of water filters

Sediment filters — mechanical filters that trap sand, rust and other solid particles in water. These filters are usually installed as the first stage in multi-stage filtration and protect more delicate filtration elements. Activated carbon filters — absorb chlorides, organic matter and other chemicals that affect water taste and odour. Especially important for espresso machines and coffee machines, where water taste directly influences beverage quality. Anti-scale or limescale filters — reduce water hardness, preventing the formation of limescale deposits on heating elements and piping. Reverse osmosis systems — provide deep water purification, removing most dissolved substances — suitable for high-end coffee equipment and specialised systems. BHS helps select the appropriate filter type based on water analysis and equipment requirements.

Equipment requiring water filters

In espresso machines and coffee machines, water quality is directly linked to the taste of the coffee extract — filtered water with ideal hardness (50–150 mg/l) delivers optimal extraction results. In dishwashers, an anti-scale filter prevents limescale build-up on heating tanks and nozzles, extending equipment life. In ice machines, the filter ensures clear, odour-free ice without aftertaste. In combi steam ovens and combination boilers, water filtration is critical — limescale coats heating elements and reduces steam generation efficiency. In water boilers and automatic beverage heaters, the filter increases maintenance intervals and reduces the need for frequent descaling. BHS offers filters for all these types of equipment.

HACCP and water quality requirements

In equipment processing drinking water — beverage heaters, ice machines, coffee and tea machines — the water filter is part of the food safety system. Drinking water must comply with national standards and the Drinking Water Directive, but additional filtration improves organoleptic properties and reduces risks for customers. The HACCP plan should include regular checks and filter replacement frequency as a control point. Regular filter replacement according to the manufacturer’s recommendations (usually every 3–6 months or after a set volume of water) is part of the HACCP maintenance schedule. BHS helps select and replace water filters on time.

HoReCa usage scenarios

In a café specialising in specialty coffee, the filter is a prerequisite for equipment quality — without proper water purification, even the best coffee loses its aroma and flavour profile. In a restaurant with active dishwashing, replacing the filter once a season can extend the dishwasher’s life by years, preventing limescale damage to the heating system. In a hotel bar with an ice machine, the filter ensures clean, appealing ice in drinks — quality ice is also a presentation issue. In a fast-food chain with multiple coffee machines, a standardised filter replacement routine reduces the risk of unexpected repairs.

Frequently asked questions

How often should the water filter be replaced? Replacement frequency depends on water hardness, equipment usage intensity and filter capacity. In coffee machines, usually every 3–6 months or after 500–1000 litres of water. In dishwashers — according to the manufacturer’s instructions, often once a year or after a set number of cycles. For equipment with high water hardness, replacement is more frequent.

How to choose the right filter? Key parameters: filter connection size, capacity (litres) and filtration type (sediment, activated carbon, anti-scale). BHS helps identify the right filter based on the equipment model number or existing filter parameters.
