SimPure T1-400 RO System 1-Year Replacement Water Filter Set, 7 Pack

Our water is really bad. It clogs up a reverse osmosis in no time. The frustrating thing is that these will only last a few months before needing to be replaced. But they work.

They are pretty easy to change once you put the holes together/ inside the filter. I think it took me around 10 minutes to do it but for some people, it will take about three minutes because I couldn’t get the holes together right with the filter at first until I got the hang of it.

They were easy to change.

Good filter and no issues so far. We’ve been using it for about a year now and are very happy with it. We’re a family of 6, so it gets used a lot, and it has held up really well. No leaks, no problems, and the water tastes clean and fresh. Overall, we’re very satisfied with it and would definitely recommend it.

Worked fine for a year until it was time to replace the filters. So many issues from leaks to unpleasant taste of water. We contacted Customer Services on several occasions and they are taking their time replacing the defective filters. It has been over a month. Just frustrating!

I didn’t realize how bad our water was until after we installed and used these filters! Our water went from testing at over 250 ppm to 1, and the water tastes better than bottled water! We have recommended it to so many friends and family members, too!

From the first 4 filters inserted, two had O-Ring problems. I was able to salvage O-Rings from previous filters. Next round I am going to try some food grade silicone grease. Note: Vaseline is not recommended as it may degrade the O-Ring itself.

I bought the SimPure T1 Series 1-Year Replacement Filter Pack for my T1-400UV tankless RO system, and it worked exactly as it should. The filters fit perfectly and installation was super easy. It’s a simple twist-and-lock setup and only took a few minutes to replace everything. The system recognized the new filters right away with no errors. Once installed, the water tasted noticeably better—clean, clear, and no strange smell or aftertaste. The water flow also stayed consistent, which was important for me. The filters were well packaged and clearly labeled, so there was no confusion during installation. They feel solid and comparable to the original filters that came with the unit. I like that this is a full 1-year replacement set, so I didn’t have to figure out which filters to buy separately. It’s not the cheapest option, but it’s worth it for compatibility and peace of mind. Cons: Only works with the SimPure T1-400UV, so double-check your model Instructions could be a bit clearer, though installation is still straightforward Overall, this is a solid replacement filter pack if you own the T1-400UV. It restored water quality and keeps the system running smoothly. I’d definitely recommend it.
