PROQ 550 Replacement Under Sink Reverse Osmosis Review

The problem is that they sell it as a complete package with a membrane that doesn't need to be changed every time. They don't offer a package without it. I didn't see the instructions for this set either, but I just took a picture of the order and placed it in the same place

The perfect replacement for the filter in my reverse osmosis system. The only problem I had was not being able to change the end pieces on the smaller Puroflo taste and odor filter. Mine has larger threads and uses push-in fittings with 3/8" plastic lines. Received them a day after ordering. Good service! They even include a QR code for a replacement instruction video.

Excellent price for the whole set. Once the tank is empty, simply unscrew the old ones (keep them upright as they will leak everywhere) and screw in the new ones, making sure the o-rings are in place. I usually have paper towels/rags underneath in case I don't roll it right the first time. I love that it also includes a polishing filter as it makes a huge difference in flavor. Will definitely order again!

My parents just moved into a house with this filtration system. The filters needed replacing, so I ordered them. My friend said they were relatively easy to install.

If we can resolve the issue I will edit my review.

The twist/unscrew method used on these filters made replacement a breeze and before I knew it the system was delivering good, clean water again. The quality of the filters is identical to the original equipment filters.

If you have a slurry system, you need these filters and membranes. Liquid Solutions charges 199.99 for a filter change once a year and 250.00 for a membrane change every two years. These are EXACTLY the same filters! You just have to replace them with the old ones. Make sure you have a towel and a bucket or something else to put the old ones on. Installation is easy. with the blue label) of them, and you will need a wrench to replace the smallest one. Otherwise you are ready to go.

After the old filters were removed and new ones installed, they continued to leak. I've tried reinstalling them multiple times and they keep leaking. After spending hours searching the internet to find out why, I finally contacted Puregen and they said they would send me some new o-rings. This should be a known issue as there were no other known troubleshooting methods. New o-rings arrived (4 days after purchasing the drinking water) and were in fact a different size (smaller than the ones on…
