4" Green/Orange/Blue Screen Refill for our 4" Box Frame

These Air Filters are ONLY for our customers with a 4" metal box frames that we used to offer.

Our 4" multi-layer screen filters are a smarter, more affordable alternative to traditional pleated filters—designed to improve airflow, capture more dust, and help your HVAC system run more efficiently. Pleated filters usually collect the majority of dust in high efficiency filters OR have good airflow in cheeper ones... ours are the only ones we know of that do both!!!

What they do and why they are so good:

Superior Dust Capture + Better Airflow
Unlike standard pleated filters that trap particles only on the surface, our three-layer design captures dust throughout the entire filter. Each colored layer increases in density, targeting particles by size as air flows through.
✔ More effective filtration
✔ Less airflow restriction
✔ Helps reduce dust and allergy symptoms
✔ Can improve energy efficiency—especially in larger homes or locations with multiple filters

In fact, poor airflow and dust on the unit's coils from inefficient filters is one of the leading causes of HVAC system failure.

Built-In Antimicrobial Protection
Our filters are treated with a safe, non-migrating antimicrobial agent that helps prevent the growth of mold, mildew, and fungi on the filter itself—keeping your air cleaner and healthier in any climate.

Captures Microscopic Particles
The final green layer is slightly tacky and designed to trap the smallest particles, including:
• Pollen
• Pet dander
• Dust mite debris
• Fine dust and some bacteria

This not only helps reduce allergy symptoms but also keeps your HVAC coils cleaner—lowering maintenance needs and energy costs.

Long-Lasting Performance
Our filters can last up to 6 months while still maintaining strong airflow.
(Homes with pets, high occupancy, or severe allergies may require more frequent changes.)

Hypoallergenic & Eco-Friendly
Designed with sensitive households in mind, our filters also produce less waste compared to traditional options.

Important Note on Filter Life

Every home is different. While our filters often last longer than standard options, we recommend monitoring performance regularly. Waiting too long to replace a filter can:
• Increase energy usage
• Strain your HVAC system
• Lead to costly repairs or breakdowns
