Air Purifier Sizes Chart 2026: CADR by Room Size & Concern (AHAM Standard)
Sizing chart + calculator Based on AHAM AC-1 Reviewed by the WhatSize editorial team
Quick answer
Use the chart below to find your air purifier size by room square footage and concern level. A 300 sq ft bedroom with normal concern needs a CADR 200 smoke/dust rating; for allergies or smoke, target CADR equal to the full room size. All recommendations follow the AHAM AC-1 standard. Need an exact number? Use our free calculator for a custom CADR in 60 seconds.
Air Purifier Sizing Table: Minimum CADR by Square Footage & Concern
| Room Size | Normal Concern AHAM 2/3 rule |
Allergies or Pets 1:1 CADR |
Smoke / Wildfire Highest smoke CADR |
|---|---|---|---|
| 100 sq ft | CADR 65 | CADR 100 | CADR 100+ |
| 200 sq ft | CADR 130 | CADR 200 | CADR 200+ |
| 300 sq ft | CADR 200 | CADR 300 | CADR 300+ |
| 400 sq ft | CADR 265 | CADR 400 | CADR 400+ |
| 500 sq ft | CADR 330 | CADR 500 | CADR 500+ |
| 600 sq ft | CADR 400 | CADR 600 | CADR 600+ |
| 800 sq ft | CADR 530 | CADR 800+ | CADR 800+ |
| 1,000 sq ft | CADR 665 | CADR 1,000+ | CADR 1,000+ |
How to read: Find your room’s sq ft on the left. Pick the column that matches your concern. The cell gives the minimum AHAM-verified CADR. Allergies / pets uses the 1:1 rule (CADR ≥ room sq ft) for 4.8+ ACH. Smoke / wildfire uses the highest published smoke CADR rating. Color key: green = standard sizing, amber = upgrade, orange = high-output, red = whole-home or commercial unit.
Adjustments: When to Increase CADR
High Ceilings
For ceilings over 8 ft, add 5% per extra foot. A 10-ft ceiling needs about 10% more CADR.
Open Floor Plan
Use the total connected area (e.g., living + dining + kitchen as one), not individual room sq ft.
Heavy Smoking or Cooking
Add 50% to smoke CADR. Cigarette smoke, gas stoves, and wood fireplaces are the hardest particles to clear.
Example: 400 sq ft bedroom, 10-ft ceilings, mild pet dander = 265 (base) × 1.10 (ceiling) = ~290 CADR, rounded to CADR 300.
CADR Coverage: Small vs Medium vs Large vs Whole-Home
| Feature | Small (100-200 sq ft) | Medium (300-500 sq ft) | Large (600-800 sq ft) | Whole-Home (1,000+ sq ft) |
|---|---|---|---|---|
| Min CADR (smoke) | 65–130 | 200–330 | 400–530 | 665+ |
| Typical Power Draw | 20–50W | 40–80W | 60–120W | 100–200W |
| Noise Level | 25–45 dB | 30–55 dB | 40–60 dB | 50–70 dB |
| Filter Life (HEPA) | 6–12 months | 6–12 months | 9–15 months | 12–18 months |
| Price Range | $60–$200 | $150–$500 | $300–$900 | $700–$2,500 |
| Best For | Bedrooms, offices | Living rooms, nurseries | Open floor plans, basements | Whole-house, asthma sufferers |
CADR vs ACH: What's the Difference?
CADR (Clean Air Delivery Rate) measures how much clean air a purifier delivers per minute, in cubic feet per minute (CFM), tested against three particle types: smoke, dust, and pollen. ACH (Air Changes per Hour) is the result of how many times the room's air volume is fully filtered per hour. To convert: ACH = (CADR × 60) ÷ room volume in cubic feet. 5 ACH is the EPA-recommended minimum for allergy and asthma sufferers; 4.8 ACH matches the AHAM guidance for sensitive groups.
Normal (general air quality)
3-4 ACH is sufficient. Matches the AHAM 2/3 rule (CADR = 2/3 of room sq ft).
Allergies, asthma, smoke
4.8-6+ ACH required. Uses the 1:1 rule (CADR = full room sq ft). See our CADR vs ACH guide for the full math.
Air Purifier Sizing FAQ
How do I use this air purifier sizes chart?
Find your room's square footage in the left column. Pick the concern column that matches your situation: normal (general air quality), allergies or pets (CADR equal to room sq ft), or smoke/wildfire (highest smoke CADR). The intersecting cell gives the minimum CADR. Then apply adjustments: +5% per foot of ceiling above 8 ft, and for open floor plans, use the total connected area.
What CADR is good for allergies?
For allergies and asthma, target a CADR that delivers 4.8+ ACH (air changes per hour) for your room. This typically means a CADR equal to your room's full square footage (not just 2/3). Look for purifiers with separate dust, pollen, and smoke CADR scores — the pollen CADR matters most for seasonal allergies.
What size air purifier for a 500 sq ft room?
A 500 sq ft room with normal concern needs a CADR 330 purifier (per the chart above: 500 × 0.67). For allergies or pets, upgrade to CADR 500. For smoke or wildfire season, target CADR 500+ from a unit with a verified smoke CADR rating on the AHAM directory.
Does ceiling height affect air purifier sizing?
Yes. A room with 10-ft ceilings contains about 25% more air volume than the same floor area with 8-ft ceilings. Add 5% to the CADR requirement per extra foot above 8 ft. For a 400 sq ft room with 10-ft ceilings: 265 base × 1.10 = ~290 CADR, round up to CADR 300.
