If you’re serious about growing top shelf product hydroponically, you know that water quality is absolutely everything.
And now Global Garden has released high quality replacement RO filters for a fraction of the cost that you’ll find from HydroLogic. They are actually made at the same facility. Interested? Read on.
Since you’re here, you probably depend on a reliable reverse osmosis (RO) system to make sure your plants are getting the cleanest, purest water that is free of excess minerals (I’m looking at you calcium bicarbonate), chlorine, heavy metals, and other contaminants that could slow growth or disrupt nutrient uptake.
But even the best RO systems need fresh filters and membranes to continue performing at peak output.
I’m excited to introduce the latest RO replacement filters and membranes designed specifically for GrowMax and Hydrologic systems.
Why RO Replacement Filters Matter
Every RO system relies on a series of filters to remove impurities before water reaches the delicate membrane. Over time, these filters get clogged with sediment, chlorine, and other debris, reducing efficiency and lowering water flow. If you’re noticing a drop in performance, slower filtration, or a change in water quality, it’s time to swap in fresh filters and a new membranes.
Upgrade Your GrowMax and Hydrologic Systems with New Filters
The latest replacement filters and membranes are designed for maximum efficiency and longer life. Whether you’re running a GrowMax Mega Grow 1000 or a Hydrologic Evolution RO system, these filters will work for your system. You’re getting the same filter at a fraction of the cost.
With new replacement filters you’re getting:
- Improved Filtration: Return the filter to it’s clean state so it can perform at it’s best. Advanced carbon and sediment filters remove more contaminants, protecting your plants from harmful chemicals.
- Same Lifespan: These filters are the same as the ones you’ll get from HydroLogic. Same quality. Same Materials. Same Product. LOWER PRICE.
- Higher Flow Rates: When you replace your filters you’ll see an immediate improvement in flow rate. That’s because your old filters did their job.
- Perfect Fit: Engineered for seamless compatibility with GrowMax and Hydrologic systems – no guesswork required. Just install, flush 10 gallons through, and you’re ready to go!

Choosing the Right Filters for Your System
Not all the filters get replaced at the same frequency. Here’s what you need to look for:
- Sediment Pre – Filters: These remove sediment before water reaches the RO membrane. They keep the other filters running longer. Seriously important to replace these frequently; typically replaced about every 6 months.
- Carbon Filters: Essential for eliminating chloramines and organic compounds. Swapping these out a regularly also extends your membrane’s life. Figure every 6 months on these. Maaaaybbeeee you can stretch it a year, but it probably isn’t doing much after the first 6 months…
- RO Membranes: The undisputed work horse of any RO system. It is responsible for filtering out 99% of dissolved solids, or more. Usually more than 99%. Most membranes last 1 to 2 years before needing replacement. This depends largely on how contaminated your water is. You’ll see a big bump in water output after replacing a clogged up old membrane.
What Makes The New GrowMax Replacement Filters Stand Out?
These new replacement filters aren’t just compatible with your GrowMax or Hydrologic system – they exceed industry standards for filtration and durability.
- Carbon Filters: Made from premium grade activated carbon derived from coconut shells, these filters have a higher porosity for superior chlorine and chemical absorption. They outperform standard carbon filters, lasting longer and ensuring better water purity.
- Sediment Filters: Constructed from melt blown polypropylene microfiber. These filters capture particles down to around 5 microns. Helping to protect your system’s membrane from clogging and degradation. Their multi layered design provides better dirt holding capacity while maintaining optimal flow rates.
- Industry Leading Materials: Unlike generic replacements, these filters use top tier materials that maximize efficiency and extend system life. With these upgrades, your existing GrowMax or Hydrologic system will function like new – for a fraction of the cost of buying a whole new unit.
How to Replace and Maintain Your Filters
Keeping your RO system running smoothly is easy if you follow a consistent maintenance routine. Here’s a quick breakdown:
- Turn Off the System: Shut off the water supply and drain the system.
- Replace Pre Filters and Carbon Filters: Simply unscrew the old ones and swap in fresh filters.
- Swap the RO Membrane (If Needed): Remove the old membrane, insert the new one, and reassemble.
- Flush the System: Run water through for a few minutes to clear out any loose particles.
Where to Get These New Filters
These new replacement filters and membranes are available through authorized hydroponics retailers and our online store, of course. Check your RO system’s manual to confirm the right dimensions, and always buy from trusted suppliers to ensure quality.
Wrapping it up
It’s that simple to get consistent, high quality water for your hydroponic setup. Just keep replacing your RO system with fresh filters. It really is a no brainer. With these new replacement filters for GrowMax and Hydrologic systems, you’ll get better filtration, longer life, and improved flow rates – keeping your plants growing at their max. Just stay on top of your maintenance schedule, and your water quality will never be a problem.
Happy growing!
