Quality Membrane Filter

By Male in 60s and over from Solomons , MD on 3/1/2025 10:05:09AM

I purchased this to replace the original membrane in a Seawater Pro RO Watermaker installed in 2018. I’ve spent the past few months in Boot Key Harbor running the watermaker weekly. TDS readings were climbing every time I ran it. I installed this Spiropure membrane and TDS readings went from almost 400 to 62- major improvement!
