The **NSF Certified Premium Standard Reverse Osmosis Membrane** is the heart of your filtration system, designed to turn "mystery tap water" into pure, crystal-clear H2O. Whether you need **75, 100, or 150 GPD** (Gallons Per Day), this component guarantees that 99% of impurities—from chlorine and arsenic to heavy metals—stay out of your glass and your grow room, ensuring you start with a perfectly clean base.
Many growers and users think that simply having a filter is enough, or worse, they use tap water believing that "if it's drinkable, it's fine for my plants." They limit the use of reverse osmosis only to the kitchen, ignoring that water quality is the number one variable in the success of a crop. They settle for water with high EC levels and chlorine that kills the micro-life in the substrate.
The cost of this mistake is huge: nutrient lockout, pH fluctuations that drive you crazy, and plants that never reach their genetic potential because they are stressed processing heavy metals. Plus, you end up spending a fortune on bottled water for yourself or changing pre-filters too often because your current membrane isn't efficient. It's a waste of money and potential.
The solution is to install this **NSF Certified Membrane**. It is not just a spare part; it is a versatile upgrade that works perfectly for both your domestic health and your indoor grow. By removing up to 99% of dissolved solids, it gives you total control, allowing you to drink pure water and feed your plants exactly what they need, without interference.
If you are serious about growing, you know that water is the vehicle for everything. Using this membrane allows you to start with a **Base EC of 0.0**. This is critical, especially if you use hydroponic and aeroponic systems where precision is everything. By removing chlorine and chloramines, you protect the beneficial bacteria and fungi in your root zone.
Imagine preparing your nutrient mix knowing that every PPM comes from your cannabis fertilizers and not from the rusty pipes of the city. This membrane ensures that your plants absorb nutrients without blocking, resulting in explosive growth and a harvest that tastes like the strain, not the chemicals in the water.
Beyond the grow room, this membrane transforms your kitchen. Forget about carrying heavy jugs of bottled water or worrying about microplastics. With the NSF certification, you are guaranteed that the material (PPSU) is safe and the filtration is real. It is ideal for drinking, cooking, and even for your pets.
The difference is noticeable in the taste: coffee tastes better, ice cubes are completely transparent, and you eliminate that subtle "pool taste" of chlorine. It is the smartest way to get value from your equipment, ensuring that you and your plants hydrate with the best possible quality.
Don't know which version to choose? It depends on your daily demand and patience. Here is a quick guide:
Generally, it lasts between **2 to 5 years**, depending on the hardness of your water and how much you use it. If you notice the EC rising or the flow dropping drastically, it's time for a change.
Yes, it removes almost all minerals. For growing, this is great because you add CalMag to the exact level you want. For drinking, the water is very light and pure.
It works with standard pressure (min 3-4 bars), but if your pressure is low, a booster pump will help you get those real 150 gallons per day and reduce waste water.
Not at all. It goes inside the central housing of your RO system. Just make sure to pay attention to the direction of the flow (check the rubber seal) and you're done in 5 minutes.
I'll be honest with you: I don't have patience. That's why I use the 150 GPD version. When I have to prepare the nutrient tank for the week, I don't want to spend the whole afternoon waiting for the water to come out. I use it to fill a 200-liter drum, add my CalMag base, and from there I add the fertilizers. Since I started using these NSF membranes, I've noticed that the pH is much more stable in the reservoir. Plus, knowing that what I drink at home passes through the same quality filter gives me peace of mind. If you grow in hydro, this is not an expense, it's the best investment you can make.

I replaced my old membrane with this NSF Certified one, and the difference in water taste is incredible. It's so much cleaner, and I feel much better knowing what I'm drinking.
