What Does the NSF Label on My Pentair/Everpure Water Filter Mean?

 Millions of people take the safety of their food, water and consumer products for granted on a daily basis. Why? Because of three letters: NSF. Founded in 1944 as the National Sanitation Foundation, the foundation changed it’s name to NSF International in 1990 as they expanded services beyond sanitation and into global markets. NSF certification is your key to making sure that the products you use meet strict standards for public health protection. Choosing a product certified by NSF lets you know the company complies with strict standards and procedures imposed by NSF.

There are important reasons to look for NSF certification when purchasing a water filter;

  • Performance claims may be based on internal testing only.
  • Sometimes stated capacities are misleading.
  • In capacity claims it’s not always clear what percentage of chemical contaminants are actually reduced.

NSF Certification ensures that:

  • The contaminant reduction claims certified are true and accurate.
  • The materials of construction do not add anything unwanted to the water such as lead.
  • The system is structurally sound.
  • Advertising claims are true and accurate.

From extensive product testing and material analyses to unannounced plant inspections, every aspect of a product’s development is thoroughly evaluated before it can earn our certification. Most importantly, NSF certification is not a one-time event, but involves regular on-site inspections of manufacturing facilities and regular re-testing of products to ensure that they continue to meet the same high standards required to maintain certification over time. If for any reason a product fails to meet one or more certification criteria, NSF will take enforcement actions to protect you, including product recall, public notification or de-certification. If you have any questions about the quality of the filter that you are currently using and whether or not that filter has an NSF certification please ask us about your filter  below or call our team at 800-942-7873.

Water Hazards in Building Systems

NSF pushes forward with Hazard Analysis and Critical Control Point (HACCP) training to reduce risk of microbial, chemical and physicals hazards in building water systems.   

Every year, tens of thousands of preventable injuries and deaths are caused by exposure to microbial, chemical, and physical hazards from building water systems. Utilizing HACCP guidelines to building water systems builds a framework for identifying potential hazards and specifies measures for control to ensure building’s water supply safety. HACCP is a program that provides the necessary training to understand best practices procedure for maintaining a facility water supply.  Filter Pure Systems supports the continued focus by NSF to provide guidelines to promote safe and healthy water.

When working with our Healthcare facilities, we verify with them the level of NSF certification needed by water systems to remove designated contaminants.  NSF 42 certification for water filtration covers systems designed to reduce Aesthetic or non-health related contaminants.  These contaminants include chlorine, taste and odor, and particulates that may be present in public and private drinking water. In the water supply for a hospital, this is not enough protection for the immunocompromised patients.  We recommend utilizing NSF 53 standards at point of use sources for patients that may be susceptible to microbiological exposure. NSF 53 systems are certified to reduce specific health-related contaminants. These contaminants may be microbiological (including cyst and legionella), chemical (including disinfection byproducts, pesticides, herbicides, and insecticides), and particulates.  The first step, we take in securing the quality of our Healthcare facility is to ensure we have a solid foundation of filtration to protect the staff and patients. Using the industry-leading brand Everpure allows us the flexibility to meet the needs of our clients without sacrificing quality or reliability. Let us help you establish a guideline of how to secure the quality of your water from Point of Use to Point of Entry systems.  To view more information on the HACCP training program, please visit nsf.org. For more information or to discuss your current water filtration system, please contact our Health Care & Lodging Specialist, Todd Leach. Click here to ask us a question!

Keeping our Soldiers Safe

For over 30 years, Filter Pure Systems has been keeping our soldiers safe by keeping their drinking water SAFE, especially our boys on the seas. Did you know that a survey was done to determine the risk of contaminated drinking water aboard eleven different US Naval ships? The findings showed that every ship had a moderate risk of chemical contamination in production, storage and distribution systems. This was due to volatile organic compounds, total petroleum hydrocarbons, disinfection by-products and lead.

The U.S. Navy has recognized Everpure Bromination as the safest, most reliable and easy to use method of water disinfection aboard their ships and Filter Pure Systems is proud to provide them with those systems. Bromination was first registered for use in 1976, treating potable water by using polybrominated ion exchange resin. Bromine is a natural occurring element that is found as bromide in living organisms and is a common component in seawater. A large portion of onboard and offshore illness can be caused by this. 

The revolutionary bromine-based systems provide an excellent alternative to chlorine, while de-chlorination systems can be retrofitted to bring cleaner taste to pre-chlorinated water. Ideal for ships of any size, or even off-shore platforms, our Everpure Marine bromination systems won’t corrode filtration equipment like chlorine can. 

Chlorine also carries a fire hazard safety warning and bromine does not. The bromine cartridges hold the polybromide resin, which is non-toxic, and more importantly, non-flammable. Everpure’s de-chlorination systems can also be retrofitted to work with existing chlorination systems, removing the unpleasant taste and smell of chlorine.

Remember, water is the fuel for the United State’s most important military weapon, our Soldiers! So it is a priority to make sure their water is fresh, clean, and most importantly, SAFE!  To learn more about Everpure Marine water filters, contact Filter Pure Systems, Inc. today. We work closely with distributors and customers to ensure that they get the best water filter systems for their needs. Whether you need quick-change cartridges — or a completely new bromination system — Filter Pure Systems, Inc. is here to help! Contact us online or reach Customer Service at 1-800-942-7873.

Don’t Forget About the O-Ring!

First, what is an O-ring? An O-ring is a doughnut, or torus shaped seal typically used to prevent the passing of air or fluid. O-rings are used to keep fluid or air IN or OUT of a defined space. This device helps to keep the water tight or air tight integrity of a filter housing or filter application. O-rings come in a wide variety of sizes and different types of materials; Types of Material

  • Buna-N®
  • Ethylene, Propylene
  • Silicon Encapsulated with FEP, an FDA-approved material
  • Silicone (Solid)
  • Teflon® (Solid)
  • Teflon® Encapsulated with FEP
  • Viton® (Solid)

    To extend the o-ring’s effectiveness there are some things you can do: Remove and inspect the o-ring at every filter change or every time the housing is opened, as well as applying the manufacturer’s approved lubricant. The protectant/gel, usually made of silicon is inexpensive and is easy to apply. If there are signs of any wear or improper form of the o-ring, the o-ring must be replaced immediately prior to restarting the filter system.    The life of an o-ring varies based on how you take care of it and what it is made of. It is very important to your operation to make sure you have the proper o-ring for your filtration application. If you have any questions on changing out your o-rings or whether you are using the proper o-ring for your system, I invite you to submit a question below or call our team at 1-800-942-7873.

How Often Do I Change My Water Filter?

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. If you have a water filter or filter model not included in the list above, and have a question regarding how often you should replace your filter, I invite you to submit a question below or call our team at 1-800-942-7873.

The Best Espresso in Town!

Every single morning before arriving to work, Amy stops by her local Starbucks and orders her usual venti latte. They know her there by name and are happy to send her on her way with her triple espresso shot drink. Amy said that her morning espresso kick starts her day and without it, well, you would probably find her half asleep at her desk, struggling to focus on her work.

Espresso can be a vital part of someone’s day, like Amy. Did you know that over 55% of the US drink espresso? That percentage is equivalent to 150 million people! That’s A LOT of espresso! 

Did you also know that Espresso is 90% water! It is a key essential ingredient in espresso preparation. So having a water filtration system becomes a must, especially in areas with hard water. Not having filtered water will affect the taste of your espresso as well as the lifespan of your equipment.  So what is the best water filtration system for your espresso machine?   Well, here’s a couple options to consider: The Claris System 5-Stage Filtration Process

  • Pre-filtration
  • Carbonate hardness adjustment
  • Fine filtration
  • Highly efficient carbon block removes harmful contaminant and unpleasant odors and tastes
  • Solid membrane filter removes particles down to 5 micron for highest equipment protection
  • Operates in vertical or horizontal position

 

3 -Stage Blending: Softens, Buffers, and Filters Water
  • Utilizes ion exchange resin with buffering capabilities and high capacity coconut carbon filtration
  • A small amount of carbon filtered water bypasses softening resin to allow proper initial hardness. 
  • Buffering prevents water from becoming too acidic. 
  • It also reduces hardness in water that can cause minerals to build-up in espresso equipment. 
  • It also reduces chlorine, off tastes and odors. Cartridge replacement is simple, quick and clean. 
*The QC7I-Twin ESO7 System is pictured to the right.
Depending on your espresso machine and water quality needs, your commercial water filtration system may differ. Give us a call and we’ll be glad to help you in sizing the right system.

What Causes Limescale Build Up?

What is scale? As rainfall descends, it picks up CO2, which makes water slightly acidic. By the time it reaches the earth, it is now a natural solvent. As it seeps down to the underground aquifers, it dissolves mineral along the way, becoming “hard.” Hard water is generally concentrated with four hard minerals: calcium, magnesium, carbonate, and sulfate. Every water supply has some dissolved mineral content.How does scale form? When energy is applied to hard water, the minerals can drop out of the solution and settle on surfaces. This is called scale, the most common of which is limescale. These minerals can form a hard crust that can cause many problems with equipment, from clogging to increased energy requirements. To understand the process that allows dissolved mineral content to rebuild solid rock, it is important to understand the condition of pH. The scale for pH is measured from 0.0 to 14.0, with 7.0 as a perfect neutral. In general terms, water supplies with a pH below 7.0 have a greater acid content and tend to dissolve rock into minerals. Water supplies with a pH above 7.0 have a lower acid content and tend to build mineral scale. There are two key conditions for scale formation:

  • The pH level must be neutral or above
  • There must be an energy transfer, cooling or heating, to act as a catalyst.

How does scale affect water-using equipment? Mineral deposits such as limescale create major problems for foodservice operators with ice, coffee, espresso, steam and warewashing equipment. Mineral scale can clog tubing and small orifices, coat heating and cooling elements, and result in increased detergent usage. Scale also causes reduced energy transfer and efficiency loss, resulting in increased energy demands for cooling or heating, and increased operating costs. Many water-using appliances, from coffee brewers to ice makers, are susceptible to limescale build-up. Steamers and combi ovens are among the most susceptible. As water boils and evaporates, minerals remain and become concentrated. Because of these high concentrations, steamers can require frequent deliming—an acid cleaning process that removes mineral scale. This process is harsh to the equipment surfaces and decreases equipment life. Freezing water can also cause scale to form. Commercial cuber-type ice makers require more service to correct scale build-up than any other equipment commonly used in foodservice. Like steamers, commercial icemakers leave a high concentration of minerals as most of the water becomes ice. The resulting residue is a murky mixture full of sediment and growing crystals that restricts tubes, fouls pumps, clogs orifices, scores valves, and causes ice to hang in clumps. Fortunately, scale growth can be reduced by adding small amounts of polyphosphates to water. Polyphosphates are completely safe and nontoxic, and many occur naturally in foods or are added during processing. They are also used in the treatment of drinking water to combat corrosion and scaling. Most scale-producing situations can be resolved more effectively with a point-of-use water treatment system that couples fine filtration and a polyphosphate feed. Fine filtration reduces particles that act as nucleation sites for scale formation. These particles speed up the scaling process and can add as much as 60 percent to the weight of the scale, depending on the particles in the source water. Filter Pure provides many systems meeting these specifications for home use, vending and office applications, and commercial foodservice. Types of scale The appearance of scale varies infinitely and depends on the impurities that are present in the water. For example, pure limescale is pure white, but sediment and turbidity due to dust, dirt and mud may color it. Common contaminants have these color properties: Treating scale There are three methods for reducing scale:

Coke Freestyle and Everpure!

Ever since Coca-Cola came out with their new Freestyle Coke Machine, we’ve been getting call after call on Everpure’s CLM filtration systems! WHY? Because Everpure CLM has recently been validated by a third party lab to meet the tccc specifications for point of use filtration systems for the Freestyle machines! Hooray!! Being an Everpure master distributor, we are proud to carry this line of CLM water filter systems. But why the CLM line? What is CLM? I’m glad you asked! CLM is short for chloramine. As you might know, chloramine is a chemical compound made by reacting ammonia with the active ingredient in chlorine bleach. According to the Environmental Protection Agency, chloramines provide better protection against bacterial regrowth in water system. But chloramines can still effect the taste and odor of your water and can cause, through time, damage to your water applications. The specifications for the Coke Freestyle machine requires all taste and odor to be removed, the chlorine/chloramine levels to be less then 0.5 ppm, and sediment removal. Everpure’s CLM line meets all the filtration requirements for the Freestyle machine. It reduces chloramines, chlorine and other offensive contaminants that can adversely effect the taste and odor of the beverage. It’s sub-micron technology reduces dirt and particles 1/2 micron in size.  It improves the taste of fountain beverages and helps retain the drink’s carbonation. Have you ever received a complaint that your soda taste flat? Well, here’s your solution! The CLM line also protects your drink system’s seals, pump, tubing and small orifices from clogging, corrosion and abrasive wear. It is also NSF certified under NSF/ANSI Standards 42 and 53. The CLM line comes in single, twin, triple and quad systems. We also have systems with a pre-filtration option. So if you are apart of a restaurant using a Coca-cola Freestyle machine or you currently service a Freestyle machine, contact us today for more information on Everpure’s CLM line and how we can help you. You can also check out our CLM line on our website! Click here: EVERPURE’S CLM LINE!

Meet the OW Family!

This lovely family of water filter cartridges delivers premium quality drinking water for bottleless coolers and drinking fountains. Their unique filter blend uses activated carbon to reduce chlorine taste and odor and other offensive contaminants. Like most of Everpure’s carbon water filters, the OW family contains a precoat submicron technology which reduces dirt and particles as small as 1/2 micron in size. Check out my blog about Microns to see how small a 1/2 micron really is! But beware of the GIARDIA cyst!! The OW family inhibits scale from building up in your home water cooler, your water dispenser, or your drinking fountains. Keep an eye out for my up-coming blog about Scale!! Let’s break down this family and see what’s unique about each filter! The OW200L (P/N EV9619-06) has a rated capacity of 480 gallons. Its overall dimensions are 17″H x 3.25″ diameter. Its service flow rate is at maximum 0.5 gpm. This cartridge is commonLY used in office drinking water systems and home drinking water systems. In fact, that’s what I have installed under my sink at home. The OW2-PLUS (P/N EV9634-01) and the OW4-PLUS (P/N EV9635-01) are essentially the same. The only difference is their capacity rating and size. The OW2-PLUS is rated at 1,000 gallons and 10.25″H x 3.25″ Diameter. The OW4-PLUS is rated at 2,000 gallons and 14.5″H x 3.25″ diameter. But unlike the OW200L, they both contain a KDF media that can remove lead to below the Federal Action Level of 10 ppb. All the OW replacement water filter cartridges are NSF Certified under NSF/ANSI Standards 42 and 53, which means these cartridges get the job done! We gladly stock the OW family and for more information about the OW family, contact us at 1-800-942-7873 or click on the “Live Help ONLINE” link on the left of your screen.
