If you compare the various models from winix, this is on the higher end for capacity. That means that if you have a room that's significantly smaller than what this unit is rated for, you can use it on a lower setting and get the same cleaning as a smaller unit on a higher setting.

I returned the C610 for the C909 for several reasons:
- The C909 takes a standard Filter A - 115115 which you can get cheap after market filters for, or even cheap deals on the OEM ones (low as $25).
- The C909 is quieter than the C610 for the amount of air it moves.
- The C610 only works well on the turbo speed but is very loud. The high speed on C610 is a joke and doesn't move much air at all compared to the C909.
I'm planning to pick up another of these for a larger room to see how well it does, but for a bedroom, it works well at reducing pollen. Just know that the smart app is kinda crappy for iOS and Android and you must connect to a 2.4GHz wireless network for it to work.Sign up for a Slickdeals account to remove this ad.
