T830
How we chose
We compared the Winix T and A series on the specs that matter for a larger room: listed coverage, noise, fan speeds, filtration stages, weight and current price. Every unit here uses 4-Stage filtration and an LED air quality indicator, so those two specs don't separate them. Fan speeds range from 4 on the A230 to 5 on the AT40, T500, T810 and T830.
Coverage and noise are where the lines split. The A230 is listed at 246 sq ft and 25 dB, the T500 at 251 sq ft and 25.4 dB, and the AT40 at 410 sq ft and 22 dB. The T810 and T830 are both listed at 418 sq ft and 23.8 dB. Weight runs from 6.7 lb on the T500 and 6.8 lb on the A230 up to 10.2 lb on the AT40, T810 and T830.
On price, the A230 is $99.99, the T500 $119.99, the AT40 $199.99, and the T810 and T830 $224.99 each. The AT40 costs $100.00 more than the A230 and $80.00 more than the T500; the T810 and T830 cost $25.00 more than the AT40 and $105.00 more than the T500. Each of these prices sits at its 90-day low, flat against a 90-day high equal to it.
Who should skip these
Skip these if your room is much larger than the listed coverage. The A230 covers 246 sq ft, the T500 covers 251 sq ft, and the AT40 covers 410 sq ft. The T810 and T830 each list 4.8, which is far below the others, so neither is a fit for a full-size room.
Skip these if you need a non-tower form factor. All five are towers, and the footprints are close: the A230 and T500 measure 9.5 x 9.5 x 14.6, the AT40 measures 10.24 x 10.24 x 19, and the T810 and T830 measure 11.3 x 11.3 x 20.4.
On price, the A230 is $99.99, the T500 is $119.99, the AT40 is $199.99, and the T810 and T830 are $224.99 each. The AT40 costs $100.00 more than the A230 and $80.00 more than the T500; the T810 and T830 cost $25.00 more than the AT40 and $105.00 more than the T500.
How to choose the right one
Start with coverage. The A230 is rated for 246 sq ft, the T500 for 251 sq ft, the AT40 for 410 sq ft, and the T810 for 418 sq ft. If your room is around 250 sq ft, the A230 and T500 both fit; if it is larger, the AT40 and T810 are the ones rated to match.
Then weigh noise and fan speeds. The AT40 runs at 22 dB with five fan speeds, the T810 at 23.8 dB with five, the A230 at 25 dB with four, and the T500 at 25.4 dB with five. The AT40 is the quietest of the group, and the A230 gives you one fewer speed than the others.
On price, the A230 is $99.99 and the T500 is $119.99, a $20.00 gap. The AT40 is $199.99, which is $100.00 more than the A230 and $80.00 more than the T500. The T810 is $224.99, $25.00 more than the AT40 and $105.00 more than the T500.
