Awesome, I've been waiting for this deal to happen again at Costco.

Some electric utilities have rebates for energy efficient air cleaners. For example, Silicon Valley Power (Santa Clara, CA) has a $75 rebate on up to 3 units, and this Winix C545 model is on the Energy Star list [energystar.gov] with >150cfm so it qualifies for the full $75 rebate each: https://www.siliconvalleypower.co...t?id=41992

That's a net cost of just $25 per air purifier!
I have had this since the last sale

Filters are hard to get cheap, not a lot of 3rd party, though compatible with different version I think S, if this is S then maybe C , cant keep them straight
I hate that it has no remote, and you cant add a remote, only option is to use app
No auto off after specific time
Given COVID , I wish I had one with a UV light
Note that 3rd party filters were hard to find last year (Type S), but now there are many offerings:

Darn it, I hate I read about the Blueair 121 and kinda want one for $200 when it's on sale.

You guys think buy this now and maybe get the other one later?

Where did you read about it? I just went to the website and it looks nice but I don't see what makes it so special for the added cost of filters?

Does the smart sensor detect the amount of particles or dust?
the description said "The Smart Sensor tells you the quality of air in your surroundings by detecting the amount of "odor" in the environment."

I spread some dust around the sensor but nothing happened, but it worked and the light turned red immediately when I spread CO2 or gas on it.
Does this mean the Winix c545 will not switch to higher mode it self when there's a lot of dust or pm2.5 in the air?

Thank you in advance, but I did not see this covered in this thread. So when it says the limit is 2 for Costco, do they mean 2 per entire account per sale period (including primary and secondary card) or is it 2 for the primary card and 2 for the secondary card too? Thank you if this has already been covered too.

UPDATE:
Able to find out my answer today. The primary member already bought 2 of the Winix air purifiers and I was able to pick up 2 myself, as the secondary member, as well.

That is correct. The C545 (and the C535 before it) only have odor sensors to control the auto mode fan speed. The auto mode does not adjust the fan based on dust or particles.

I am not rballnut, but the Fairfax VA location had over 100 as of Saturday. You could give them a call to check inventory.

I wish these Costco threads didn't go into a 'dead' state until the end of the savings period. These items always come back in stock.

Just wondering if the sensor can detect if there is mold spores? If there are mold spores will the sensor light be red?

I doubt that.
If it can only detect odor, the mold spores are particle right?
what about the smoke from cigarettes or from wildfire? odor or particle? well the sensor detect it?
It would be not that useful as a air purifier if the auto mode not detect the particle or dust.

You can doubt it all you like, but it is the truth. I have 2 C535 for 3 years and 1 C545 for a year. They detect odor only in auto mode.

Read the manual -
Odor Sensor
Detects the amount of odorous gas in the environment.
When in Auto mode, the fan speed adjusts according to
the detected amount of gas.

It only detects voc, or gasses. It cannot detect physical items such as pollens or dust, because that requires a particulate sensor.

Basically it comes with a nose sensor that can smell, but not an eye sensor that can see dust.
