"Yes, you seem to be confused. Look at the much smaller diameter, closer together nanofibers, compared to the much larger wide spread microfibers in the second photograph. The nanofibers would clearly filter smaller and more particles, yet allow more flow than the microfibers. That is how the AMSOIL synthetic nanofiber filters smaller particles and for up to 25,000 miles, compared to cellulose microfibers which are often recommended to be changed at 3,000 miles (such as PureONE). PureONE stands to sell up to 8 filters, whereas AMSOIL might only sell one for the same mileage."
Tim, do you mean the DONALDSON synthetic nanofiber filters that AMSOIL sells?
