## Questions & Answers

**Q: Is this filter for low pressure ro system or hi pressure systems?**
A: Permeate production is pretty much linear with pressure. I run mine at 80 to 100 psi and get 2.5 gpm from a two stage system - a total of three membranes. So far I am very pleased with the Hydron BW 4040 s.

**Q: Is there a 2.5”X40” membrane?**
A: Yes

**Q: Is overnight shipping available**
A: Possibly

**Q: Can you town water through this ro?**

### ⭐⭐⭐⭐⭐ 99% TDS Reduction !!!
*by H***S on 23 February 2025*

Finally installed this membrane after buying it 6 months ago. My RO system operates only on city water pressure (no booster pump). Feeding softened city water with ~550 ppm of TDS, and using a very low ~1.5x reject vs permeate flow to minimize water waste. This membrane is generating >900 ppm TDS in the reject stream and 5-8 ppm TDS in the permeate. Astounding performance !!!
