Everpure 4CB5-K Water Filter Cartridge (EV961736)

Everpure 4CB5-K Water Filter Cartridge (EV9617-36)

The Everpure 4CB5-K Water Filter Cartridge delivers high-quality filtration for vending, office coffee service (OCS), and small-to-medium ice machines. It features carbon block filtration to reduce chlorine taste & odor while filtering dirt and sediment down to 5 microns. Its KDF scale inhibitor also helps minimize limescale buildup, reducing equipment downtime. This filter is NSF/ANSI Standard 42 certified for safe, effective water filtration.

For espresso machines, we recommend the Everpure 4CB5-S or Claris Ultra, as KDF media is less effective in high-temperature environments.

How It Works

• Carbon Block Filtration: Reduces chlorine taste & odor for better beverage quality.
• Sediment Filtration: Removes dirt, rust, and particulates down to 5 microns.
• KDF Scale Inhibitor: Slows limescale buildup and inhibits microbial growth.
• Heavy Metal Reduction: Helps filter out lead, mercury, and other contaminants.

Ideal Applications

• Vending Machines: Ensures beverage consistency and taste.
• Office Coffee Service (OCS): Provides clean water for better-tasting coffee and tea.
• Small-to-Medium Ice Machines: Improves ice clarity and reduces scale-related downtime.
• Espresso Machines (Consider the 4CB5-S for Better Scale Control): For high-heat applications, a polyphosphate-based filter is more effective.

Limescale Reduction & Equipment Protection

Why KDF Media Is Less Effective for Espresso Machines

• KDF media works best in low-temperature water but loses efficiency in high-heat applications.
• Espresso machine boilers exceed 90°C, where KDF media cannot prevent mineral precipitation.
• Polyphosphate-based inhibitors (Everpure 4CB5-S, Claris Ultra) offer superior scale prevention for boilers and heating elements.

• Replace the filter every 6 months: Or when the maximum capacity is reached.

4CB5-K vs. 4CB5-S – Which One Should You Choose?

Both filters provide excellent water filtration, but they use different scale control methods:

• Everpure 4CB5-K – Features a KDF scale inhibitor that helps reduce microbial buildup and heavy metals. Best for vending, OCS, and ice machines.
• Everpure 4CB5-S – Uses a polyphosphate-based scale inhibitor, which is more effective at preventing limescale buildup in high-heat applications like espresso machines.

Everpure CB5-K Series Filter Performance & Ratings

Features

• ✅ Carbon block filtration: removes chlorine taste & odor for better-tasting beverages.
• ✅ KDF media: reduces scale buildup and microbial growth.
• ✅ 5-micron filtration: removes dirt, sediment, and rust particles.

Questions & Answers

• Q: Can I use this filter in an espresso machine?
  Yes, but it is not the best choice for scale prevention. If you want better scale control, opt for Everpure 4CB5-S or Claris Ultra.
• Q: How does KDF media compare to polyphosphate scale inhibitors?
  KDF media helps prevent microbial growth and removes heavy metals, but it is less effective in high-heat applications. Polyphosphate-based inhibitors (found in Everpure 4CB5-S) are better for preventing limescale buildup in espresso machine boilers and heating elements.
• Q: How often should I replace this filter?
  Every 6 months or when capacity reaches 6,000 gallons (22,710 L).
• Q: Is this filter NSF certified?
  Yes, it is NSF/ANSI Standard 42 certified for chlorine taste & odor, particulate reduction, and microbial control.

Coffee Parts Thoughts

If you need basic scale control and heavy metal filtration, the Everpure 4CB5-K is a great option for vending, office coffee, and ice machines. However, if you want better scale prevention for espresso machines, we recommend the Everpure 4CB5-S or Claris Ultra. Shop now for high-quality filtration that enhances taste, protects equipment, and ensures consistent beverage quality.
