What Membrane Solutions does

Membrane Solutions, LLC. is a US-headquartered (Auburn, Washington) filtration and purification manufacturer that independently develops microporous membranes (Nylon, PES, PVDF, PTFE, PP) and converts them into a broad product portfolio across five operating divisions: Life Science (biopharma sterile filtration, pleated cartridges, capsule filters), Laboratory (syringe filters, disc membranes, chromatography consumables, Labpure water systems), Microelectronics (PFA stainless steel gas filters, PTFE cartridges, CMP/photolithography filtration), Water & Industry (RO membranes, UF/MBR systems, high-flow cartridges), and Residential/Consumer (SimPure countertop and under-sink RO systems). The technical backbone is proprietary membrane formulation with hydrophilic, hydrophobic, charged, and lipophobic modifications, complemented by the MS TrustPlus Validation Center — a CNAS-certified 2,000 m² facility staffed by 50+ scientists with 100+ analytical instruments.

The business operates a hybrid go-to-market: industrial B2B sales through a Request-for-Quote system and a channel network of approximately 200 distributors across 80 countries, OEM/ODM manufacturing for top filtration brands, and direct-to-consumer e-commerce (SimPureLife.com, MSPureLife.com, Amazon marketplace) for residential water purification. Manufacturing is concentrated in four Chinese plants with complementary capacity in Seattle, and R&D runs through four China-based centers backed by 200+ engineers including 40+ Ph.D.s. Revenue streams span industrial hardware, laboratory consumables, residential hardware, OEM/ODM services, and validation/professional services, with pricing largely quote-based on industrial SKUs and fixed one-time pricing on consumer RO units.

Customer concentration is diversified across pharmaceutical, microelectronics, food and beverage, municipal/industrial water, oil and gas, and residential end markets, with no publicly disclosed anchor accounts. The company holds ISO9001, ISO13485, ISO27001, CNAS, FDA, NSF, CE, FCC, UL, ETL, SGS, RoHS, AHAM, and CARB certifications, and runs 100+ patents supporting its membrane technology. The company is privately held under LLC structure with no disclosed institutional funding rounds.
