The Sparks Overland Flat Air Filter
Let’s be honest — we use our heaters in far harsher environments than most. The stock “air filter” on many heaters offers little real protection, leaving your system exposed to dust, debris, and even wildlife.
The Sparks Overland Flat Air Filter is designed to actually protect your heater without restricting airflow.
Our mountable flat filter uses a four-layer filtration system to stop debris before it ever reaches your heater. Two washable foam layers capture both fine dust and larger particles, while the raised maze pattern allows heavier debris to fall away instead of clogging the filter. A hard intake tube section lets larger particles drop free entirely.
Cleaner air means better performance, fewer issues, and longer heater life — especially in dusty, dirty, or remote environments.
Why It Works
- 4-stage filtration system
- Washable foam layers for fine and coarse debris
- Non-restrictive airflow design
- Raised pattern sheds debris instead of trapping it
- Helps prevent clogs, contamination, and failures
- Built for harsh, real-world conditions
