The Quantum 1000 cartridge is the replacement for the Q1000 water filter system.  We also have a higher capacity Quantum Q4000 if you require greater capacity and have the additional space.

The Q1000 and Q4000 are third party tested and certified by the National Sanitation Foundation (NSF). This means that the claims that Everpure makes regarding performance and capacity have been tested and certified to be true.  This provides you with peace of mind that what you are buying will deliver on its promise of quality.

The two important standards are #42 and #53:

We recommend changing this filter on an annual basis or when the flow rate becomes inconveniently slow. Our water quality is changing all the time.  Even if you have your water tested, that is just a snapshot on that particular day, so don't be surprised if the frequency of cartridge change fluctuates from one year to the next; this is normal.  

What matters most is knowing that regardless of the water quality going into the water filter, the quality coming out will always be the same.  This is the promise that Everpure delivers on and that is why it is so important to only buy a water filter that is third party tested and certified by NSF. Without NSF, the manufacturer can make whatever claims they want.  Read more on this important certification.

Note: The Q1000 and Q4000 water filters fit exclusively in the QH3 head only
