Decent recurring deal (every 3 months or so). Note that it has a plasma generator that some people don't like since it creates ozone. But it's supposed to create both negative and positive ions that help reduce the ozone impact?
Replacement filters are about $34 for a pair from 3rd party sellers on amazon. Be aware these filters that the unit uses only have sprayed on charcoal vs. the mesh of pellets, so the smell removal will be reduced significantly compared to other units.

You can turn the plasmawave off.

sale pricing in filters at 69 doesn't make sense at all. at another 30 bucks you get the whole new system with 2 filters. The price on filters should be around $40.

Does anyone know how this compares to the 5510 that's currently on sale at Amazon?

I know the Costco unit comes with the additional year of filters. But ease of use and so on, any reccs?

I think that shows how good of a deal this is then. Might have to buy a couple.

Solid machine, but the design of the app and the control are really bad.

- plasmawave setting is not memorized. You have to turn it off every time .
- if you set the machine to auto mode, it enters sleep mode (very very low fan power) when the surrounding is dark. You can't turn off sleep mode with auto mode.
- app's air quality monitor report is close to useless.

It's smart but not that smart...
