Filter efficiency is represented by the Beta (β) ratio, this is standardized by ISO 4572 Committee and is accepted as the norm worldwide. The higher the Beta ratio number, the better the trap of the filter to stop contaminants from passing through it and back into the system.
Triple R Filter Elements offer some of the better efficiency ratios on the market. Here in the following table are some of the Beta ratios found on various Filter Elements. As seen, Triple R offers the ability to stop 99.9% of the contaminants going through some of its filter elements, a near perfect mouse-trap for contamination.
| Beta Ratio (β) | Efficiency (%) |
|---|---|
| 75 | 98.68% |
| 100 | 99.01% |
| 200 | 99.50% |
| 400 | 99.75% |
| 900 | 99.89% |
| 1000 | 99.90% |
