Everpure ProSeries 3500 Cartridge EV930035

Sale price

Premium water for your drinking & cooking needs

Bottle Water Equivalent: 2271 x 500 ml (16.9 oz) bottles

This is the replacement water filter cartridge for the ProSeries 3500 Water Filter System.

We also have two other models of ProSeries Filters; the ProSeries 1500 (750 gallons capacity) and the ProSeries 2500 (1500 gallons capacity). The 1500 and 2500 provide the same level of filtration however the ProSeries3500, at only 300 gallons, provide a much higher level of filtration, hence the lower capacity.  It is working much harder!

Please note that only ProSeries cartridges fit into ProSeries heads. 

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.

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.

        Replacement filter

        I was delighted to find a company that stocks this filter. I tried other online sites and they said that that filter was discontinued.


        There are no indications from Pentair that this filter will be discontinued anytime soon so we will continue to stock it for you!
