Filmtec 75 GPD RO Membrane vs. Competitors: Which One Is Best for You?

Hey everyone, it’s your boy back again with another hands-on update. Today, I messed around with a Filmtec 75 GPD RO membrane, and let me tell you, it was quite the experience. So, let’s dive right into it, shall we?

First off, I got my hands on this 75 GPD membrane. I heard a lot of people saying to stay away from those 100 GPD ones, claiming they’re not the real deal for reverse osmosis. Makes sense, I guess. When I started looking into it, seemed like everyone was suggesting to stay with the 75 GPD ones for the best results, especially if you’re watching your wallet.

So, I went ahead and installed it into a standard membrane housing I had lying around. It was a pretty simple process. I just replaced the old membrane with the new Filmtec one. I made sure to take note of how the old one was positioned before I removed it. Installation was a breeze, took me like 10 minutes, tops.

• Getting Started: I grabbed the Filmtec 75 GPD membrane and made sure I had my standard membrane housing ready.
• Prepping: I carefully unscrewed the housing and pulled out the old membrane, making a mental note of its position.
• Installing: I placed the new Filmtec membrane into the housing, making sure it was seated correctly.
• Sealing it up: Then, I screwed the housing back together, making sure everything was tight and secure.

After I got it installed, I ran some water through the system to test it out. It took a little bit for the water to start coming through clear, but once it did, I measured the output. I was curious to see if it really hit that 75 GPD mark, and at about 50 psi, it seemed to be doing just that. Of course, this is just a rough test, but it gave me a good idea of what to expect.

From what I can tell, this 75 GPD membrane seems to be a solid choice. It’s doing what it’s supposed to do. And based on my initial tests, it’s living up to its claims. So far, I’m pretty happy with the results.

But here’s the thing, I also came across some information about other membranes, like the Spectrapure ones. Apparently, they come pre-wetted and perform even better than the standard Dow ones, and they also have hand-tested Select series, which sound pretty premium. So I might check those out in the future. Also read that the DOW Filmtec SW30-2540 Membrane is the best one for marine water, so many choices and things to consider.

And for those dealing with some seriously nasty water, I learned about tubular membranes. They’re great for high TSS or TDS, and they’re easy to clean. But, they’ve got less surface area, so it’s a trade-off. I’ve also read that having a higher GPD membrane isn’t always better, despite improving performance, so that’s a thing to consider as well.

Final Thoughts

All in all, messing with the Filmtec 75 GPD RO membrane was a learning experience. It seems like a decent option for anyone looking to get into RO water filtration. I’m still keeping an eye out for other options, but for now, this one’s doing the trick. Always remember, picking the right membrane depends on your specific needs and water conditions. Don’t just jump on the highest GPD thinking it’s the best. Sometimes, sticking to the basics, like this 75 GPD one, might be the way to go.

Stay tuned for more of my DIY adventures, folks!
