Premium water for drinking & cooking

For ease of ordering, here is a kit of both water filter cartridges. These are the replacement cartridges for the QC4-THM drinking water system.

Keep Your System Working Optimally:

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. 

All Everpure residential systems and cartridges include a Time strip filter monitor to remind you when it's time to replace the cartridge.  Remember to buy only genuine Everpure replacement cartridges to maintain your warranty.

Read more about the versatility of cartridges you can use with an Everpure Quick-Change head.

Please note: this cartridge fits into the QL1, QL2, QL3 and QC4 heads. If you have a ProSeries head, please use the ProSeries 1500/2500/3500 cartridge

Excellent experience

I have not yet installed the new filters I just received. I have ordered filters from this company in the past and have always been well satisfied with their quality and the prompt delivery after placing my order. I'm sure these new filters will be no exception....when I can get my busy son-in-law to install them for me.


Hello Arlene, hope you had a great week so far. We are so grateful that you have been ordering from us all these years. We really appreciate your kind words.
