Boosted patient trust and comfort
“We’ve sealed everything from historic homes near Atlantic Avenue to modern builds off Lake Ida, and time after time, the 16x25x1 filter proves its worth. It maintains airflow integrity after sealing, traps more airborne particles than bulk store brands, and helps our clients see utility savings faster. It’s not just a filter—it’s part of the performance equation.”
Why Duct Sealing + 16x25x1 Filters Work: Stats + Field Insights
We don’t just rely on industry guidelines—we see these results firsthand every week in Delray Beach homes. Here’s how national data backs what we’ve proven in the field:
1. 20% of Air Is Lost in Leaky Ducts
Source: EPA.gov
- Leaky ducts waste up to 20% of heated/cooled air.
- Equivalent to running your AC with a window cracked open.
- We’ve seen this in over 80% of older homes we inspect.
After sealing + installing a 16x25x1 filter, airflow stabilizes—and bills drop.
2. Poorly Tuned HVAC Systems Use 30% More Energy
Source: Energy.gov
- No sealing = more energy = higher wear and tear.
- Common in homes with oversized or “band-aid” HVAC installs.
- Our customers often report:
- Quieter systems
- More even cooling
15–25% lower monthly bills after sealing + filter upgrade
3. MERV-13+ Filters Improve IAQ Significantly
Source: CDC.gov
- CDC recommends MERV-13+ for cleaner indoor air.
- We use MERV-rated 16x25x1 filters in:
- Homes with kids, the elderly, or allergy-prone residents
- Clinics, dental offices, and wellness centers
Clients notice fresher air in as little as 3 days.
