How often should I change my cartridges?

In order for our filters to perform as represented and to provide the best quality water possible, it is essential that filters be replaced periodically. The frequency of filter changes depends upon your water quality and your water usage. For example, if there is a lot of sediment and/or particles in your water, then you will have to change your filters more frequently than a location with little to no sediment. Be sure to replace your filters whenever you notice a decline in the performance, whether it is a drop in flow rate and/or pressure or an unusual taste in the water.

  • Prefilter
    The prefilter (coarse) cartridge should be changed when it becomes dirty to within 1/8″ of the core or when you see the outlet pressure gauge fall into the red zone. Check the pressure gauge only when the equipment is calling for water.
  • Submicron Cartridges
    The cartridges should be changed at the first occurrence of a) the gallon rating stated on the label, b) every 6 months, or c) the pressure gauge needle falls into the red zone while your equipment is calling for water.
  • ScalestickTM
    The Scalestick needs to be replaced before the Hydroblend compound is completely used up.

How do I remove the “used” cartridges and install new ones?

  1. Shut off the power to any equipment, if applicable.
  2. Shut off the filter system by turning off the water supply. Open the flushing valve to relieve the pressure.
  3. Hold the head firmly and turn the cartridge to the left ¼ turn until the rotation stops.
  4. Pull the cartridge down and out of the head. Some water may drain out of the system. Throw away the used cartridges.
  5. Hold the head firmly then align the new cartridge’s lug with the label on the head and insert the new cartridge into the head.
  6. Turn the cartridge to the right ¼ turn until the rotation stops.
  7. Turn on the water supply.
  8. Now, flush the cartridges by running water through the filter system to the drain for several minutes. Refer to the cartridge’s label for specific flushing times. Note: Be sure to shut off the flushing valve when finished.
  9. Turn on the power to the equipment, if applicable.

Why do cartridges plug up?

Our cartridges are designed to remove contaminants and particles from the water. The cartridges will eventually plug as this material is removed, therefore, plugging indicates that the cartridges are working efficiently. If a cartridge plugs soon after installation, there are various things such as construction in your area or changes in reservoir levels that may alter the quality of your incoming water from day to day. This may produce low water pressure or excessive turbidity (large number of particles) in your water, which may cause the cartridges to plug prematurely.

Why do cartridges need to be flushed?

All carbon-based filters need to be flushed to remove any excess carbon fines that are inside the cartridges. New cartridges are filled with air; therefore, flushing also removes the air from inside the cartridges and replaces it with water. The flush time is written on each cartridge’s label. This process will allow any carbon-based cartridge to function at optimum levels without affecting any equipment that may be attached. Note: Be sure to shut off the flushing valve when finished.

Can filtered water increase the life of my equipment?

Many water supplies contain small particles as well as chemicals such as chlorine. The small particles can interfere with the mechanical operation of your equipment causing premature valve failure or plugging of nozzles. Chemicals such as chlorine can be corrosive and attack the internal metal surfaces. With Everpure water filter systems, particles as small as 0.5 micron as well as chlorine will be reduced and can extend the life of your equipment.

How can I prevent scale in my steamer?

Scale is caused when dissolved minerals, usually calcium and magnesium, are deposited as a white flaky solid on to the heating elements of your steamer. This material acts as an insulator, which increases energy usage. Over time this it can cause your equipment to fail altogether. Everpure offers several products designed to reduce or prevent scale formation. One product is the Everpure Kleensteam® system, which reduces scale build up. Another alternative is the Scalestick™. The Scalestick contains a special Hydroblend™ that inhibits mineral scale deposits in low flow water-fed equipment. Our MRS ( Mineral Reduction Systems), Line of reverse osmosis products also remove minerals that cause scale. To determine how much mineral is in your water, it’s best to have your water tested, call us for a water test at 800-942-7873.

Are your products NSF Certified?

The majority of our cartridges are certified by NSF. This certification means that the contaminant reduction claims certified are true and accurate, the materials of construction do not add anything unwanted into the water, that the system is structurally sound, and that advertising claims are true and accurate. This certification provides assurance to the user that the system has been independently evaluated to confirm its performance. The certification is displayed on the cartridge’s label along with the claim; for example, chlorine reduction for 1000 gallons. Our certified products have been submitted for testing under NSF/ANSI Standards 53 and 42. For further information on NSF certification, please contact technical service at 1-800-942-1153 or information can be located on the NSF web-site, www.nsf.org

How is Everpure Treated water better than Tap water?

  • Municipalities have a primary objective of ensuring safe water. They can use a variety of technologies, but most all use some form of disinfection, either chlorine or chloramines. Unfortunately, chlorinated water has a distinctive off-taste and smell.
  • While municipal water treatment plants do meet EPA minimum requirements, they do not remove all contaminants nor do they filter for taste and odor.
  • Water always contains some dissolved mineral, and mineral is not removed by water treatment plants. This mineral causes hard scale in equipment that heats or freezes water, causing increased energy costs and reduced equipment life. Everpure offers products that reduce scale buildup.
  • As water travels from the treatment plant to your location, it can also pick up contaminants from old pipes.
  • Cysts are microbial living organisms (protozoans) that can be resistant to chlorine disinfection. Cysts have been known to cause health problems. Examples of cysts are Cryptosporidium and Giardia.
  • Not all water contaminants are bad, such as minerals, which Everpure filters do not remove. However, many contaminants such as chemicals, gasses and particles can affect the taste and smell. Some can even cause health problems.
  • Everpure removes chemicals like chlorine, along with dirt, rust particles, asbestos, small living organisms called cysts, and more, leaving you with crystal clear, clean and great-tasting water.

Why would I need a prefilter on my water treatment system?

Our quick-change filters remove contaminants as small as .5 micron. Microns are extremely tiny, in fact a human hair has the width of 40 microns. This means our filters are very effective at removing many contaminants. However, if your water is particularly dirty, we recommend placing a prefilter in front of your system. Prefilters are typically 10-25 micron, allowing them to remove the larger particles that might prematurely plug your system. Many of our systems provide a prefilter option.

How do I know if my water is treated with Chloramine?

Some municipalities have migrated from using chlorine to chloramine. Chloramine is chlorine combined with a small amount of ammonia. The addition of the ammonia allows the disinfectant to stay in the water longer, for greater distances. Chloramine is more difficult to remove from water that chlorine, and requires filters with much more carbon. There are two ways to determine if your water has chloramine: 1) contact your local water utility company, or 2) have your water tested. By testing your water for Total Chlorine and Free Chlorine, we can determine if your water is being treated with chloramines. Our CB20 line of products are effective at removing chlorine.

Doesn’t my water softener treat my water?

Water softeners use an ion exchange process. Typically sodium chloride is exchanged for hard minerals like calcium and magnesium, which makes water “soft”. Hard minerals cause a hard scale on equipment that heats or freezes water, and this scale is difficult to remove, often requiring frequent delimings. Softener systems are usually comprised of a resin tank, where the ion exchange process takes place, and a brine tank where the salt solution is created. A softener can exchange other contaminants depending on the resin used, for example it can help remove iron from water. However, a softener does not filter the water, so many contaminants such as dirt, cysts and particles can pass through a softener resin bed.
