Honeywell 16x25x5 MERV 11 Filter – Delray’s Clean Air Secret
At Filterbuy, we’ve helped thousands of Florida homeowners breathe easier—and we’ve learned one critical truth: your indoor air is only as clean as the filter you trust.
That’s why we consistently recommend the Honeywell 16x25x5 MERV 11 air filter to our customers in Delray Beach.

Florida’s warm, humid climate creates the perfect storm for indoor air quality issues—think pollen, mold spores, and fine coastal dust. In our work with Delray Beach homeowners at Filterbuy, we’ve found the Honeywell 16x25x5 MERV 11 air filter to be a standout solution for homes that need better filtration without sacrificing HVAC efficiency.
This filter is engineered to capture up to 95% of airborne particles, including allergens, pet dander, and bacteria, while still allowing for optimal airflow. Unlike lower-grade filters, the MERV 11 level is ideal for families who want cleaner air but don’t want to overwork their systems or deal with frequent replacements.
What makes it a “clean air secret” in Delray? It’s the combination of high-efficiency performance and reliability we’ve seen firsthand in coastal homes. When paired with an air ionizer system—especially during allergy season or high humidity months—it can significantly reduce respiratory triggers and extend HVAC lifespan.
Whether you’re upgrading for health, energy efficiency, or both, this filter delivers measurable indoor comfort—something we at Filterbuy have witnessed time and again in the homes we serve.
“We’ve installed and serviced thousands of HVAC systems across Florida, and the Honeywell 16x25x5 MERV 11 filter consistently outperforms expectations—especially in coastal climates like Delray Beach.

Frequently Asked Questions
What makes the Honeywell 16x25x5 MERV 11 filter better than standard filters?

In humid climates like Delray Beach, replace it every 6 months, or sooner if you have pets, allergies, or run your HVAC frequently.

Yes. MERV 11 filters trap airborne allergens such as dust mites, pollen, and mold spores. Many Delray Beach homeowners report noticeable symptom relief after switching.
Can I install this filter myself?
Absolutely. The Honeywell 16x25x5 is designed for easy installation. Just make sure the airflow arrows point toward your HVAC system. If unsure, a technician can help.
