You probably already know that water filters improve the taste of water, but that's not all they do. Water filtration serves three important purposes:

  • Remove Impurities: Commercial water filters are designed to eliminate impurities such as chlorine, sediment, and heavy metals from the water supply. By doing so, they improve the taste, odor, and overall quality of the water used in food and beverage preparation.
  • Prevent Scale Build-Up: Scale build-up caused by minerals like calcium and magnesium can wreak havoc on kitchen equipment such as coffee makers, steamers, and ice machines. Commercial water filters help prevent this by reducing the mineral content in the water, thus extending the lifespan of the equipment.
  • Protect Equipment: By removing impurities and reducing mineral content, commercial water filters help protect expensive restaurant equipment from damage and corrosion. This not only saves money on repairs but also ensures that your kitchen operates smoothly and efficiently.

How Do Water Filters Work?

Layers of material inside a water filter perform different types of filtration. The first layer is usually a sediment filter. This layer is designed to trap large particles such as dirt, sand, and rust from the water. By removing these impurities, the sediment filter helps prevent clogs and protects the subsequent filtration layers. The next layer typically consists of activated carbon. Activated carbon is highly porous and has a large surface area, making it effective at adsorbing contaminants like chlorine, chemicals, and organic compounds. This layer helps improve the taste and odor of the water.

Some advanced water filters use a reverse osmosis membrane as a filtration layer. Reverse osmosis works by applying pressure to push water through a semipermeable membrane, removing a wide range of impurities including heavy metals, dissolved solids, and bacteria. This process produces clean and pure water for cooking, drinking, and ice-making.

What Are the Types of Water Filters?

Let's take a look at the different types of water filters commonly used in restaurants:

  • Carbon Filters: Carbon filters are effective in removing chlorine, volatile organic compounds (VOCs), and unpleasant odors from the water. They are commonly used to improve the taste and smell of water, making it more palatable for drinking and cooking.
  • Reverse Osmosis (RO) Systems: RO systems use a membrane to remove a wide range of contaminants from water, including heavy metals, dissolved solids, and bacteria. These systems are highly effective in producing clean and pure water, making them ideal for applications where water quality is critical.
  • Ultraviolet (UV) Filters: UV filters utilize ultraviolet light to disinfect water by destroying bacteria, viruses, and other microorganisms. These filters are often used in conjunction with other filtration methods to ensure that water is safe for consumption.

Do Water Filters Remove Bacteria?

Yes, certain water filters can remove bacteria. Look for a commercial water filter that is specifically designed to remove these contaminants. Filters that utilize UV-C technology or have a built-in UV sterilizer are highly effective at eliminating bacteria such as E. coli and Legionella. Reverse osmosis systems are also a great choice for bacteria removal because they can filter out particles as small as 0.0001 microns.

Do Water Filters Remove Chlorine?

Yes, water filters are designed to remove impurities from water, including chlorine. Chlorine is commonly used in municipal water supplies to kill bacteria and other harmful organisms. However, the presence of chlorine can affect the taste and odor of water, which can impact the quality of beverages and food prepared in restaurants. By using a water filter with activated carbon or reverse osmosis technology, restaurant owners can effectively remove chlorine from their water supply, ensuring a cleaner and better-tasting final product for their customers.


Which Water Filters Do I Need?

There are a few key factors to consider when choosing the right water filters for your bar or restaurant. First, determine the size of your operation and the volume of water you use daily to select a filter that can handle the demand. Assess the quality of your water supply to identify any specific contaminants that need to be filtered out. Finally, consider the type of filtration system that best suits your needs, whether it's a reverse osmosis system, carbon filter, or sediment filter. By taking these factors into account, you can ensure that your restaurant has access to clean, safe water for all your cooking and beverage needs.

What's the Difference between OEM Filters and Third Party Filters?

OEM, or Original Equipment Manufacturer, water filters are specifically designed by the manufacturer of the equipment for which they are intended. These filters are engineered to meet the exact specifications and requirements of the equipment, ensuring optimal performance and compatibility. On the other hand, third-party water filters are produced by companies other than the original equipment manufacturer. While these filters may offer a more budget-friendly option, there are some considerations to keep in mind. Third-party filters may not always meet the same quality and performance standards as OEM filters, which could potentially impact the efficiency and lifespan of your equipment.

Keep in mind that using third-party filters could void the warranty of your equipment because manufacturers often require the use of OEM filters to maintain coverage. It is essential to carefully review your equipment's warranty terms and consult with a professional before opting for third-party filters to avoid any potential issues down the line.
