One of the most common questions we hear from our customers is in regards to how frequently a water filter cartridge should be changed. Whether it’s a standard sediment or carbon filter, every customer has one key priority in mind: How Long Will I Have Dependably Clean, Great Tasting Water? In other words, how can I be sure that my filter is still reducing the impurities that can impact the flavor of my water? Our standard answer: It depends. The frequency of filter changes depends upon your water quality and your water usage. For example, if there are a lot of sediment particulates in your water, then you will have to change your filters more frequently than someone with little to no sediment. If you are a large restaurant consuming large amounts of water a minute or a hospital with large ice machines, then your usage will demand more frequent filter changes. Having said that, we suggest replacement schedules that are generally as follows: Everpure High Flow CRS Quad MC2 System The most common Everpure Filtration System, mainly seen in the back of the house of restaurants should be changed every 6 months, or every 36,000 gallons. The EC210 prefilter, to the left of the MC2 filters, should be changed more frequently to extend the life of the MC2 filters. We recommend every 3-4 months. Insurice Triple PF i4000(2) System w/ 20″ Prefilter For water filtration on ice machines, sometimes it can be difficult knowing when to change the filters, especially if you see no difference in the ice. But even if the ice is fine, deep inside the machine inches of scale can be forming and ruining your machine. That’s why it is important to keep a filter change out schedule. We recommend every 6 months or however many gallons are specified on the water filters. For the system pictured to the left, the Insurice Triple PF i4000(2), change those filters every 36,000 gallons of use. Again, changing the prefilter will give your primary cartridges longer life. You should also replace your water filters whenever you notice a decline in performance, whether it is a drop in flow rate and/or pressure, or an unusual taste in the water. You should also, per the CDC, replace your water filter after any boil water advisory alert is lifted in your area. Remember: taste and odor may tip you off to the presence of chlorine in your water, but most contaminants are tasteless and odorless. For the benefit of our customers, we have set-up automatic electronic reminders that are sent when we see that their filters are due to be replaced, based on order history. We can even set-up Auto-Ship for customers that know they will need water filters by a certain date, but may not remember to place an order.
