Supporting Statistics & Insights
The HDX 20x30x1 filter is backed by data and first-hand results. Here’s how research and experience align:
1. Indoor Air Quality Challenges
- Americans spend 90% of their time indoors.
- Indoor air can be 2–5 times, even 100 times, more polluted than outdoor air (lung.org).
- In practice: families often see dust buildup and allergy flare-ups until a proper filter is installed.
2. MERV 11–13 Efficiency
- EPA notes filters in this range capture 85–90% of particles sized 1–3 microns (cloverfilter.com).
- Real homes using the HDX filter report less dust and smoother HVAC operation.
3. HEPA Benchmark for Comparison
- HEPA filters remove 99.97% of particles at 0.3 microns (en.wikipedia.org).
- While not always practical in standard HVAC systems, this sets a performance benchmark.
- HDX strikes a balance—strong filtration without airflow restrictions or high costs.
Key Insight: These stats confirm what we’ve seen firsthand—HDX filters improve daily comfort, protect HVAC systems, and deliver healthier air.
