- Wash your hands with soap and water before touching the new filter. Alternatively, wear clean nitrile or cotton gloves. This prevents oils and dirt from transferring to the media.

How Often Should You Replace Your Filter?
The standard recommendation is every 30 to 90 days, but the actual frequency depends on several factors. The best approach is to monitor the filter visually and replace it when it shows visible loading, rather than relying on a fixed calendar schedule. A filter that appears dirty on the upstream face but clean on the downstream side is nearing the end of its useful life. When both sides appear dirty, the filter is severely clogged and should have been replaced earlier.
