Exposure, primary risk & chemicals modeled
Primary risk
Fine particulate matter (PM2.5)
A quality HEPA purifier reduces indoor PM2.5 by ~45% on average in the room where it runs.
Chemicals addressed
- Fine particulate matter (PM2.5)
- Ultrafine particles (PM0.1)
- VOCs from indoor sources
- Allergens, mold spores, pet dander
- Wildfire smoke particles
Health outcomes
- Reduced cardiovascular disease risk
- Lower risk of respiratory disease
- Reduced lung cancer risk
- Lower systolic blood pressure
- Reduced inflammatory markers
The math, step by step
Study Benchmark
10 µg/m³ PM2.5 reduction → +223 life-days
Pope, Ezzati & Dockery (NEJM 2009) — largest U.S. PM2.5 longevity study
Your Actual Reduction
HEPA purifier cuts indoor PM2.5 ~45% ≈ 9 µg/m³ in breathing zone
Based on average indoor PM2.5 of ~20 µg/m³; HEPA H13 captures 99.97% of particles ≥0.3 µm
10-Year Scaling (marginal room unit)
Same PM2.5 math, then discount ~60% for overlap with whole-home filtration + second-device diminishing returns
Conservative central estimate vs. counting a full standalone “total PM benefit” in every room
Economic Value
20 days × $411/day = $8,200
EPA VSL $11.6M ÷ 77 yr ÷ 365 days = $411 per life-day
How we score this category
Effectiveness
Rated on CADR (Clean Air Delivery Rate) relative to room size, HEPA certification, and documented particle reduction in third-party lab tests. True HEPA (H13+) filters 99.97% of particles ≥0.3 µm.
Safety
Penalized for ozone-producing technologies (ionizers, UV-C without proper containment). Bonus points for units with low EMF, no plastic off-gassing, and third-party safety certifications.
Affordability
Scored on total cost of ownership: unit price + annual filter replacement cost over 5 years, normalized per 500 sq ft coverage.
Certifications
We prioritize Energy Star, AHAM Verifide CADR, CARB compliance (no ozone), and independent lab certifications. HEPA grade and MERV ratings are verified.
Life-days and economic value are population-level estimates based on peer-reviewed epidemiology using EPA Value of Statistical Life Year methodology (~$150K/year). Individual results vary based on baseline exposure, location, and health status. Not medical advice.
