4" Green/Orange/Blue Screen Refill for our 4" Metal 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. 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.

Finally—A Filter That Doesn’t Make You Choose

Most air filters force you to compromise:

Expensive pleated filters trap dust… but restrict airflow
Cheaper filters allow airflow… but let dust pass through

Why settle for one or the other?

The Best of Both Worlds

Our system is designed to do what others can’t:

✔ Captures more dust and particles

✔ Maintain strong, healthy airflow

✔ Help your HVAC system run more efficiently

Why That Matters

Better airflow means:

Less strain on your system (can help your expensive unit to last longer)
Improved energy efficiency
More consistent comfort in your home

Better filtration means:

Less dust buildup
Cleaner air to breathe
Fewer airborne irritants

In fact, poor airflow and dust on the unit's coils from inefficient filters are the leading causes of HVAC system failure... which as most people know happens in the heat of the summer when you need your ac the most.

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 microscopic 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, homes with multiple units can last longer)

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/cost
• Strain your HVAC system
• Lead to costly repairs or breakdowns
