Proline Plus Filter Replacement Compatible Kit - Made in USA, Includes All Needed RO Water Filters Including 50 GPD Membrane for 5 Stage Proline Plus Reverse Osmosis

easy to install , you can tell the difference in water taste

I installed this approximately 1 year ago on a Water World Proline Plus RO system. It is consistently reducing my total dissolved solids from around 650-700 down to around 35ppm (95% reduction). The typical RO system should be capable of a 90% reduction so I have been pleased with the performance. I have yet to change any of the pre-filters and it continues to perform. I am pleased with this replacement set and will buy again.

These products are American made

Our home had this reverse osmosis filter on the kitchen sink when we bought it. When the flow turned to a trickle, we reluctantly ordered the kit to replace it. We’re a couple in our 60s with various decrepit joints so we were afraid it would be too awkward and difficult to get under the sink, but it really wasn’t that bad. We saved money by not paying someone else to do it.The instructions left a lot to be desired, but we found a YT video that was more detailed. We didn’t order the special wrench because we owned a rubber-strap oil filter wrench, and it worked fine for the task.If you’re at all handy, you should be able to complete the task in under an hour.We enjoy having great-tasting and clean-smelling water even though we live in an area with lots of sulfur, calcium, and added chlorine in the water.

Satisfied with installation and performance

I changed all 5 stage filter 4-5 months ago. Initially couple weeks my ppm measure drop to 20 range. Around a month it went to 40-50ppm, still acceptable. But just around 5 months, I am getting 120-130ppm, my tap water consistently stay around 230 ppm range. By suggestion , membrane change after 2 years. Not satisfaction on if I need to change so frequent to maintain the drinking quality.

Works great

Membrane filter is not pentair brand. It's more of a generic off name brand. Besaré! Website description is inacurate. For the price you'd think you'd receive quality stuff.Update 8-18-23I've changed my raring to 5 stars because their customer service mad either right and sent the correct membrane filter. Thank you!
