Vertex Water Machine EasyPur Filter Kit with RO Membrane
Filter Replacement Kit with RO Membrane for Vertex WaterMachine EasyPur Reverse Osmosis System
INCLUDES:
NOTE: Q Series Filters are 12" in Length and not 10" like the original filters in the EasyPur Reverse Osmosis System.
We offer two replacement filter kits so you can get exactly what you need — and avoid paying for filters you don’t.
Year 1 Kit (shown here):
Ideal for your first full replacement, this kit includes all filters plus the RO membrane, which typically lasts up to 24 months.
Year 2 Kit found (Without RO Membrane):
After the first year, you only need to replace the pre- and post-filters, since the RO membrane is still good for another year. This kit helps you save money while keeping your system performing like new.
*Filters may need to be replaced more often than indicated, depending on water contaminant levels and volume of water being treated.

"I’ve been replacing these same filters since 2018 and ordering from ESP Water since at least 2020. Never had an issue. This last time, I was left without my system mid installation because one filter in my kit was wrong for once. It was a simple mistake and they made it right. I did kind have to argue more than I would have liked with the customer service department about it being the wrong one though."
"The replacement RO membrane was different than the original, and came with no specs or hookup instructions. I got no response from email support, but phone support was very quick and super helpful."
"Great price along with free shipping made me switch from my previous supplier. Shipping was timely also. will be buying my filters from you in the future. Thanks!"
"I was mid replacement when I realized I wasn’t sent my Sanitizer I ordered and paid for. Super frustrating."
"Called ESP and explained the membrane fitting was leaking and they offered to send me a fitting. Glued it and it seems to work."
"This is my second time ordering with ESPWater. My items arrive quickly, the quality is great and I can’t find a better price for the filters I need. Overall I’m very happy with this company."
