Vertex PT 4.0 RO Filter Replacement Kit with Membrane
Filter Replacement Kit with Membrane for Vertex PT-4.0, PT-4.0/P, and PT-4.0/PP Reverse Osmosis System
INCLUDES:
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 (Includes RO Membrane) available on this page:
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 (Without RO Membrane):
After the first year, you only need to replace the pre-filters and post-filter, 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 had to buy different Carbon filter as my Vertex System only takes Quick Connect filter not threaded one. I called the customer service but it seems they don't care. Their website does not inform about this thing. Not going to order again."
"Exactly what I needed"
"Ordered the replacement filters & membrane for my Vertex PT4.0 and fit perfectly! My RO is now working as good or better than ever. I will certainly reorder from them every year."
"Everything went smoothly"
"The connections on the final filter changed so the filter wasn't usable. It would be hopeful when the design of the system changes. They send the filter with an adaptable connection. We had to put the original filter back in until we can go to the store and buy a connection. Not user friendly."
"I just purchased a house that had a reverse osmosis system, but I had no idea when the filters were last replaced. This filter pack fit the system. It took about 20 minutes to replace all the filters and the system is working just like new."
"Way to early to give a report."
"The filters were exactly as advertised, a great value, and made in the USA!"
"Arrived on time and right without mistakes"
"Happy with service and product"
