Frequently asked questions
What room size is the Winix C610 listed for?
Start with the room-size rating, then compare it with the room where the unit will sit. ENERGY STAR lists 384 sq ft for this model, with a smoke CADR of 248 cfm. Ceiling height and layout change real-world results, so treat it as a rated figure and leave the clearance the maker’s manual asks for around the intake and outlet.
How much energy does the Winix C610 use?
The listing gives 235 kWh per year and an efficiency of 6.2 cfm per watt.
What filter does the Winix C610 use, and does it produce ozone?
ENERGY STAR lists the filter type as HEPA-Type. Ozone emissions are listed at 1 ppb. Compare the stated filter type rather than marketing language such as “HEPA-like”. Noise level is not part of the ENERGY STAR dataset (n/c), so see the maker’s specifications for decibels.
