Winix AM90 Wi-Fi Air Purifier

Winix AM90 Wi-Fi Air Purifier, 360sq ft Room Capacity, Amazon Alexa and Dash Replenishment Enabled

I love my 2 Winix WAC9500 Ultimate Pet True HEPA Air Cleaner with PlasmaWave Technology filters. Been great for going on 5 years now. Been dry enough lately that the vent that pulls in cooler outside air at night into the computer room is pulling a fair bit of dust too.  So I decided to get a third. The WAC9500 is discontinued and none of the current models use the same filters. The Winix HR900 Ultimate Pet True HEPA PlasmaWave Technology Air Purifier, 300 Sq. Ft, White is the follow up to the 9500 but as far as I can see it does not clean the air much better than the AM90. It is even rated for a larger space.  So I bought an AM90 which is $100 cheaper and is supposed to work with Alexa. It also uses the filter, Winix 115115 Replacement Filter A for C535, 5300-2, P300, 5300, 5500 which I ordered once by accident for my 9500s. The filters the 9500s use, Winix 114190 Replacement Filter B for 9500, U300 Air Purifiers are also more expensive and use a plastic cassette that each replacement comes in and so makes for more plastic waste.


The setup via the android app was so bad I almost sent it back. Note the C545 model needs it own skill and app.

To get it to finally finish I had to:

  • Get the timing right to see the direct WiFi connection. (You have to connect before unit quickly times out)
  • Have the phone forget the 5Ghz WiFi
  • Let it use the default city as the location.

Took me about 5 tries to get all the way through, having to start over from scratch even after I could see it was connected to my network.

Even trying to change the city later caused the app to completely hang during search. So I ended up leaving it on the default as useless as that is.

Note the Alexa name entered into the app (as in Bedroom) is what shows in lists in the app though in the web interface it shows as Bedroom Winix Air Purifier. You will probably want a longer name, though you can change in the Alexa app later.

Alexa integration:

For Alexa to see the instructions say you have to enable 2 skills

Since I use a password manager I find linking accounts easier in the web interface. Be sure to select Approve before clicking submit.

The Winix Custom Skill is the old "Ask Winix" style.

The Winix Smart Home Skill is supposed to let you say "Alexa, turn on WINIX", "Alexa, increase WINIX" and "Alexa, decrease WINIX" Though this did not work for me. So I looked to create a routine to alias it. After not seeing it on the list at first ( showed as a a fan named bedroom) I decided to rename it.

I tried triggers of "more air" and "increase air" to turn up the cleaner bey neither worked. The less intuitive "full power" did. I then made a matching "half power" routine to set it back to normal.

Reviews complain about WiFi connectivity so I'll have to update after I've had it online for awhile.
