CADR Calculator for Baby Nursery
Find the minimum Clean Air Delivery Rate for your room.
Infants breathe 30–60 times per minute — 2–3× faster than adults. This means they inhale proportionally more airborne pollutants per kilogram of body weight. Clean air in a baby's nursery is a health investment, not a luxury.
For baby nurseries, we recommend 5–6 ACH with True HEPA (H13) filtration. The priority is particulate removal (dust, pollen, mold spores) rather than gas-phase pollutants, unless there's new furniture or recent renovation.
Safety is paramount: choose a purifier that produces ZERO ozone (no ionizers, no UV-C, no electrostatic precipitators). Ozone is harmful to developing lungs. Also ensure the purifier has no small parts, no exposed blades, and a stable base.
📐 How CADR Is Calculated
Formula: CADR = (Sq Ft × Ceiling × ACH) ÷ 60
AHAM recommends ≥ 4.8 ACH. Allergies: 6 ACH. Smoke/Asthma: 8 ACH.
Based on 240 CFM minimum Smoke CADR:
💡 Tips for Baby Nursery
- ✓ NEVER use ozone-producing purifiers in a baby's room — ozone harms developing lungs.
- ✓ Choose a purifier with no exposed blades, no small parts, and a stable tip-proof base.
- ✓ Run on the quietest setting overnight — babies need quiet for healthy sleep development.
- ✓ Place the purifier 3–5 feet from the crib, not directly next to it.
