Where to buy a good RO water filter membrane? Top picks for your home water system!

Okay, so, I’ve been meaning to upgrade my home’s water situation for a while now. You know, better quality drinking water and all that. After digging around, I figured a reverse osmosis system is the way to go. But then came the tricky part – which membrane to choose? Man, there are so many options out there, it’s kinda nuts!

I started by checking out some online stores and found that some of them sell products from China. I have the option to customize the size or color, but that doesn’t help me find the right membrane.

Then I started looking at some brands, one name that kept popping up was Dow Filmtec. Heard a lot of good things about their SW30-2540 model. Apparently, it’s a solid choice, especially for marine water makers. This guy, Rich, who runs something called Cruise RO Water Makers, he swears by it. Says it’s an industry standard. That sounded pretty legit, so I dug a bit deeper into that one.

Next, I needed to figure out my water pressure situation. Turns out, that’s pretty important. If your pressure is too low, the whole RO thing doesn’t work as well, and you end up with less water. So, I grabbed my trusty pressure gauge and checked my home’s feed water pressure. Thankfully, it was within the range that works well with most membranes, including the Filmtec one.

But then I stumbled upon these things called tubular membranes. From what I gathered, they’re good if your water has a lot of gunk in it – high total dissolved solids (TDS) or suspended solids (TSS), or even a lot of oil. They’re easier to clean and don’t clog as much. The downside? They’re kinda bulky for the amount of filtration they do.

My Choice

  • Checked my feed water pressure: Made sure it was good enough for an efficient RO process.
  • Looked into Dow Filmtec SW30-2540: Seemed like a reliable choice, used by a lot of people, even professionals.
  • Considered tubular membranes: They sounded interesting for really dirty water, but probably overkill for my situation.

After weighing all of this, I decided to go with the Dow Filmtec SW30-2540. It seemed like the best balance of performance, reliability, and it’s not too huge. Plus, that Rich guy’s endorsement gave me some extra confidence. I mean, if it’s good enough for boats dealing with seawater, it’s probably more than enough for my tap water, right?

So, yeah, that’s my little adventure in the world of RO membranes. It was a bit of a learning curve, but I feel pretty good about my choice. Now, I just gotta get it installed and enjoy some crystal-clear H2O! Cheers to that!
