1-Year Replacement Filter Kit with RO Membrane for Microline TFC-400 Reverse Osmosis System

INCLUDES:

  • STAGE 1 - 1x 5 micron Sediment Pre-Filter (S7011) - Replace Every 12 Months
  • STAGE 2 - 1x Sediment/Carbon Pre-Filter (S7028) - Replace Every 12 Months
  • STAGE 3 - 1x RO Membrane TFC 50 GPD (S1229RS) - Replace Every 24 Months
  • STAGE 4 - 1x Inline Carbon GAC Post Filter (S7206W-JG) - Replace Every 12 Months

We offer two replacement filter kits so you can get exactly what you need — and avoid paying for filters you don’t.

  • Year 1 Kit found on this page (Includes RO Membrane):
    Ideal for your first full replacement, this kit includes all filters plus the RO membrane, which typically lasts up to 24 months.

  • Year 2 Kit (Without RO Membrane):
    After the first year, you only need to replace the pre- and post-filters, since the RO membrane is still good for another year. This kit helps you save money while keeping your system performing like new.

By offering two kits, we make it easy to follow the recommended replacement schedule and reduce waste — so you only buy what your system truly needs.

*Filters may need to be replaced more often than indicated, depending on incoming water contaminant levels and volume of water being treated. Read the full review for the Microline TFC-400 RO drinking water system.

GREAT product!! No complaints at all!
Size: 90 Count (Pack of 1)
So I got this product as an experiment. I don’t like taking prescriptions - but that is just me. I have the most boring job on the planet. And it’s all I can do to make it just through the morning without falling asleep. when I saw this product, I decided to give it a try. I am totally and completely shocked how well this works. It doesn’t make me jittery at all. It just makes me feel alive and alert and ready to roll. And I can focus on the monotonous tasks at my job. When I do take them, I have to take them in the morning. they do last all day - again - this is for me. but I found when I took them in the afternoon, I was still wide awake at 1:00am. Which put a damper on my trying to drag myself out of bed and to work at the most boring job ever.

good experience so far
Size: 60 Count (Pack of 1)
I’ve been taking Qunol Brain Health for a little while now, and overall I’ve had a good experience with it. What stood out to me first was that it didn’t upset my stomach, which I’ve run into with other supplements. I feel like I’ve noticed a difference in my ability to stay focused during the day, especially when I’m working on tasks that usually make my mind wander. My energy levels also feel a bit steadier, without that late afternoon mental fog. The capsules are easy to swallow, and I like that it combines several ingredients aimed at supporting memory and concentration rather than having to take them separately. It’s obviously not an overnight miracle, but with consistent use I do feel sharper and more mentally “on.” The only downside for me is the price—it’s a little higher than some other brain supplements I’ve tried. But considering the quality and how it makes me feel, I think it’s worth it.

Way too expensive

Great product, but Costco is more affordable even when not on sale.

Definitely worth it!!
Size: 60 Count (Pack of 1)
After completing one bottle, I have to say that I have noticed a difference in not just my short term memory, but overall, how I can focus throughout the day. I'm on my second bottle now.
