Water filters in their simplest form are, well, water filters – they filter out the impurities in water so that it is safe to consume. Some types of water filters are used to filter ice and drinking water, whereas others are used to filter all of the water in an establishment, e.g. hard water, fluoride water, conditioned water. Nonetheless, it’s important to know when you should be replacing your filters and the importance of water filtration in a restaurant.
You should also know the difference between filter heads, pre-filters, replacement filters, scale removers, and water filter systems. Here’s a quick overview on what each of these categories are.
Filter heads go on top of water filters and hold them in place. You’d typically unscrew the filter from these to change out your water filters, i.e. they’re the head of the water filter system. Filter heads should only have to be replaced when they are broken, leaking, or are clogged.
It’s easy to know when to replace an old filter if you can read the specifications on the filter itself. However, if you’re unsure, try to time a replacement every six months or when the water begins to show signs of the following:
- Water pressure drops significantly. Many water filtration systems have a PSI (pounds per square inch) indicator needle. If that needle is in the red or below 30 PSI, replace your filter.
- The water tastes or smells funny.
- Mineral deposits (or scale) start to build up in the equipment the water is being filtered through.
If you replace your water filter and you’re still seeing signs of cloudy water or bad taste, you’ll likely need to use a pre-filter as well.
Pre-filters add an additional layer of filtration to help purify water. As the name suggests, these filters are used in the beginning stages of filtration – when water that needs to be filtered comes in, the pre-filter works to filter out sediments like rust and silt particles. They also help extend the life of your replacement filters.
If you have hard water, you likely are very familiar with scale build-up. Scale forms in the piping of faucets and equipment and causes issues overtime. It also causes hot water heaters and equipment that uses hot water to run less efficiently, because scale makes heat transfer much more difficult. If you have an issue with scale, you’ll likely need to invest in scale remover and a scale inhibitor (also known as a scale stick). The scale inhibitor simply holds the scale remover, whereas, the scale remover is the action-Jackson of getting rid of scale build-up without adding any impurities to the water that is being filtered. The scale remover Tundra offers is non-toxic and safe for foodservice equipment.
Water Filter Systems
Finally on our list are water filter systems. Tundra provides over 50 water filter systems that are complete with filter heads and replacement filters. Some come with a scale inhibitor and scale remover and others are much larger, providing more water filtration. The size and type of a water filter system you should be investing in, depends on how you run your business and what equipment you already have (or are planning on purchasing). Although most equipment will have guidelines on what filtration system is best, you also need to be aware of how much water and ice your business will be using – including room for future growth (you don’t want to spend money on a smaller ice machine that you’ll likely outgrow within a year’s time).
