Independently tested by IAPMO R&T - an ANSI-accredited third-party laboratory
Product advantages: What sets
MWT apart
Choosing a point-of-use water filter for a healthcare, hospitality or commercial environment involves evaluating pore size, bacterial reduction efficacy, service life, and regulatory compliance.
The data below is independently validated by IAPMO R&T under ASTM F838-20 and covers each of these criteria for MWT products.
SIX CERTIFIED ADVANTAGES
Certified performance data : MWT vs typical market range
Log 10 vs Log 7 - what the numbers mean
Bacterial reduction is expressed on a logarithmic scale.
Each step up represents 10x more bacteria eliminated per liter.
Bacteria remaining per liter filtered:
Log 6 - 99.9999% 1 per 1,000,000
Log 7 - 99.99999% 1 per 10,000,000
Log 10 - 99.99999999% 1 per 10,000,000,000
MWT products are certified to Log 10 by IAPMO R&T
under ASTM F838-20, under controlled laboratory conditions.
How physical barrier filtration works at 0.08 µm
At 0.08 µm, the membrane acts as a physical barrier - pathogens larger than 0.08 µm cannot pass through the pores.
Published size ranges from microbiological literature:
Legionella pneumophila 0.3–0.9 µm
NTM 0.2–5 µm
Pseudomonas aeruginosa 0.5–0.7 µm
E. coli 1–2 µm
Salmonella 0.7–1.5 µm
Each pathogen above has a minimum published diameter larger than 0.08 µm. Filters with pore sizes above 0.08 µm may not physically retain the smallest cells in these ranges.
All MWT performance data is derived from controlled laboratory testing conducted under ASTM F838-20 protocols by IAPMO R&T, an ANSI-accredited independent certification body. Results represent performance under controlled laboratory conditions — actual results in real-world applications may differ. Service life figures are estimates and depend on source water quality, usage conditions and operating environment. Typical market range figures are based on publicly available product specifications and published industry standards — individual products may vary. No specific competitor products are referenced by name. MWT products are manufactured in an FDA-registered medical device establishment (Owner/Operator No. 10094411) and an EPA FIFRA-registered facility (Est. No. 105402-NLD-1). These are facility registrations under 21 CFR Part 807 and the Federal Insecticide, Fungicide and Rodenticide Act respectively — they are not product approvals or product clearances.
