Frequently Asked Questions
1. How often should I be cleaning my filter?
We recommend you check it out every 5-6,000 miles; we find it easiest to just check on it at the same time we perform oil changes. Take it out, tap off any loose debris, dirt, bugs – then you can use your best judgement on whether or not it’s time for a full wash. Drivers in dustier, off-road conditions will need to wash more often than city drivers.
2. Should I be oiling my filter? Is this filter pre-oiled?
Our filters are made with media that can be oiled, but they are not pre-oiled. We don’t recommend oiling unless you are in a dusty environment and need the extra support of the oil to catch the really fine particles. If you do oil, make sure to use a cleaning and oil kit from a reputable brand, and take care to follow application instructions carefully to prevent over-oiling.
3. Do I need a pre-filter, or filter sock?
Pre-filters are great at keeping large debris like bugs, grass, rocks, etc, out of your pleats, which makes maintenance even easier. Our pre-filter is also semi-hydrophobic, so when water hits it a good amount of that water beads and rolls off, keeping your filter drier which is best for longevity and performance. The airflow impendence of the pre-filter is negligible.
4. How long will these filters last, how many washes?
It really depends on your environment, how often you clean, and whether or not you use a pre-filter; if your filter media is beginning to get frayed or wrinkled you might want to consider swapping in a new filter. With average use, this is normally after 2-3 years.
