How to size a purifier for a large room

Multiply room sq ft by ceiling height (usually 8 ft) to get cubic feet. Divide by 60 (minutes per hour) and multiply by target ACH (4 for allergies). That gives you required CFM. A 600 sq ft room x 8 ft = 4,800 cu ft. For 4 ACH you need 4,800 x 4 / 60 = 320 CFM. The Core 400S (260 CFM) hits 3.25 ACH there; the Core 600S (410 CFM) hits 5.1 ACH.

Noise at full power

Large-room purifiers are noisier because they move more air. Core 400S maxes at 52 dB; Core 600S at 54 dB; Vital 200S at 54 dB. At fan speed 3 (where most people leave them on auto), all three sit comfortably under 45 dB.

Open-plan homes and basements

If your living room flows into kitchen + dining without doors, treat the entire footprint as one room. Most US open-plan main floors are 1,200-1,800 sq ft - only the Core 600S realistically delivers 4 ACH at that size.

Smart features pay off in large rooms

PM2.5-sensor auto mode actually matters in big rooms because cooking, vacuuming and fireplace use spike air quality. The Core 400S, 600S and Vital 200S all have laser PM2.5 sensors and respond within seconds.
