There is a list of Google home commands in the app:

The Google Home service recognizes most English commands, but other languages may recognize only power/fan speed/mode controls or may not operate depending on Google's voice recognition success rate.

The command can be called by replacing "air purifier" with "device name" as shown below.

Ex)
Hey Google ~ , turn on the "air purifier"
Hey Google ~ , turn on the "living room"
Hey Google ~ , turn on the "living room air purifier"

Power Control
Hey Google ~ , turn on the air purifier
Hey Google ~ , turn off the air purifier

Fan Speed Control
Hey Google ~ , increase air purifier fan speed
Hey Google ~ , decrease air purifier fan speed
Hey Google ~ , set air purifier fan speed to low
Hey Google ~ , set air purifier fan speed to middle
Hey Google ~ , set air purifier fan speed to high
Hey Google ~ , set air purifier fan speed to turbo

Mode Control
Hey Google ~ , set air purifier to auto mode
Hey Google ~ , set air purifier to manual mode
Hey Google ~ , set air purifier to sleep mode

Display Control
Hey Google ~ , set the air purifier display lights to turn on
Hey Google ~ , set the air purifier display lights to turn off

Device status Query
Hey Google ~ , is Air purifier on?
Hey Google ~ , what is the air purifier fan speed set to ?
Hey Google ~ , what mode is set on the air purifer ?
Hey Google ~ , is the display off on the air purifier ?
Hey Google ~ , what is the indoor air quality on the air purifier ?

Costco is selling new online for $99.99 after $30 off
·
Costco bundle comes with 2 extra sets of filters which is $60 when they go on sale. So you're only paying $40 for a brand new unit from Costco compared to $65 for a refurb.

The woot page indicates one HEPA filter and four carbon filters, but new this unit comes with two HEPA filters and five carbon filters. I suspect it is a listing error as the one of each extra is shipped in the unit whereas the extras are outside the unit.

Currently $99 at Costco through the end of the month.

If having issues connecting the unit to WiFi - move your phone away from the unit. This is common for most smart devices. Start the setup process in a room with the unit, then once the unit is trying to connect, take your phone away from the unit. I replicated the connection issues by sitting in the room with two units, the.n resolved the issue by walking into a different room.

I have Google home and connected this successfully. Lol but can't figure out how to turn it on via voice command. Any ideas? Fan and air purifier is a no go =/

Bought four new ones from Costco a few months back. All but one have the fan wobble issue. I thought they took care of that? Perhaps I got old stock?

I reached out to support over a week ago and haven't heard back. I love these things but striking out with support and fan issues.

I would bet on this having one HEPA filter. New from Costco you get two, refurb from Winix is usually $69 and you get one HEPA filter/ 4 or however many extra carbon filters.

I also wish these didn't have the fan wobble issue, I have 4 of these and two got the wobble after about a year and a half/two years.

Here's for Alexa. You have to reconnect every couple of weeks though which is super annoying.

"Alexa, ask WINIX to turn on my air purifier."

"Alexa, ask WINIX for speed setting to low (or medium, high, turbo, auto, sleep mode)"

 "Alexa, ask WINIX to turn on plasmawave."

"Alexa, ask WINIX for filter status."

 "Alexa, ask WINIX for indoor air quality."

"Alexa, ask WINIX for outdoor air quality."

 "Alexa, ask WINIX for my air purifier model name."

 "Alexa, ask WINIX for the phone number (or the location, or the business hours) of the customer care center."

 "Alexa, "ask WINIX about the status of my device."

Would this help filter some airborne dust from my 1000sq ft basement?
