M1000 and L5505 Water Filter Cartridges

The M1000 and L5505 Twist-Off water filters are incredibly user-friendly. To replace the filter, just detach the filter body from the permanent head with a twist of the wrist.

The new filter cartridge is just as easily replaced by threading it into the head.

This purification system is independently certified to remove the things most people are concerned about in their tap water: lead, chlorine and other harmful chemicals, bad taste and odor. However, this commercial-grade purification system leaves the beneficial minerals in your purified water. The M1000 water filter has been tested to NSF performance Standard 42 and Standard 53. It is independently certified for chlorine, lead, cysts, bad taste and odor reduction. Specifically, it is a 1 micron, block, granular activated carbon filter with lead reduction media. It is certified for 1,200 gallons

Offices with more than 10 people or water coolers that get lots of use will want to change the water filter cartridges twice a year to keep your water pure. (We will send you an email reminder.)

Our filters undergo rigorous testing and independent verification for performance. Each filter is rated at .5 gpm with a maximum pressure of 125 psi and. Class 1 filtration media.

All filters should be installed on cold water lines only. NOTE: Activated carbon filters are not intended to be used where the water is microbiologically unsafe or with water of unknown quality without adequate disinfection.
