Filter Health 101
Why Dirty Filters Matter
Air filters don't just "catch dust." When they're overloaded, they quietly degrade your system and the air in your space. Most manufacturers recommend checking every 30–90 days — yet a lot of systems go far longer, especially ductless mini-splits, HEPA units, and commercial setups that "seem fine."
01
Restricted Airflow
Overloaded filters strain equipment and choke circulation.
02
Lost Efficiency
Your heating and cooling system works harder for less output.
03
Re-Circulated Debris
A clogged filter pushes what it can't hold back into your space.
04
Shorter System Life
Neglected filters accelerate wear on the entire unit.
05
Air Quality Drift
The decline is gradual — and easy to miss until it isn't.
The Campaign
What Is the Dirtiest Filter Contest?
We're inviting homeowners, businesses, facility managers, and contractors to submit photos or videos of their dirty air filters for a chance to win prizes — and possibly be featured in our 2026 promotional content. Every system type qualifies. No judgment on how long it's been. If it's overdue, it's eligible.
Eligible System Types
- Residential HVAC systems
- Ductless mini-splits
- Portable HEPA air purifiers
- Commercial & industrial filtration
- Specialty systems & units
What to Submit
- 1–3 photos or a short video
- "Before & After" shots (optional but encouraged)
- System type + approximate time since last check
- Remove personal info from the shot

Our Purpose
Why We're Doing This
We sell filters — but more importantly, we help people understand their systems.
This contest raises real awareness around routine filter maintenance — not through stock photos or technical jargon, but through actual evidence submitted by the people living and working in these spaces.
Most systems are more neglected than their owners realize. Seeing that played out by other real people normalizes the conversation and removes the stigma of "I should have done this sooner."
Clean air doesn't start with buying a filter. It starts with checking the one you already have.
Ready to Check Yours?
If your filter hasn't been checked in the last 90 days, now's the time. Enter the contest and find out what you've been living with.
