Can I use a fine filter (e.g. a one micron filter) to achieve similar performance to ISOPur?
No. A one micron filter is almost like plugging up your system. The backpressure build will be substantial, and will eventually blow through the filter. If the filter doesn’t blow, it will rapidly get plugged up by contamination and require frequent and expensive changeouts. In addition, very fine filters create a static charge, which makes varnish a large problem.
