Quite frankly, I never use the wifi on mine. I'm not sure why it's really needed. Just gimme a light every 45 days to clean prefilter and I'm good to go
The unit looks so much deeper than the C535 and C545. It's likely that the motor and/or fan blade is/are significantly deeper than those models to bump the room square feet from 360sf to 500sf on this model.

My concern with this $160 price is that $200 will sometimes get you TWO C535s or C545s based on past sales, and having TWO units would be pretty crazy air cleaning, if placed 20-40 feet apart. I'd think that would be significantly more effective, although it would be more in electricity.

Please need to keep in mind that these units catch particles floating in the air. You're still going to get dust particles in many places because they're too heavy to continually float in the air, and find themselves near the intake of an air cleaner. Air cleaners do not do your dusting, swiffering, or vacuuming for you, but they all tend to imply that they create a dust free home. Huh.



Many similarities, but very different air volume cleaned, through an upgraded fan blade and/or motor.
My kids use them for white noise sometimes and sometimes forget to turn them off. It's nice to set them back to auto mode without even being at home. It's also nice to see more info about the device and filter use in the app.

I have two C545 and the wifi on both became dysfunctional one year in... thinking about returning them even if they are a few years old for these newer ones.

This thing is a beast. Great price for the amount of coverage it provides compared to lesser models.

How does this compare to the Instant brand one from fp yesterday? Seems the Instant brand one is rated to cover ~double the square footage.

This seems to be a 9800 rebadged by costco. Uses the same filters as c535 and c545. 115115.
Only difference seems to be it's wireless works, auto sleep at night, and the fan is quieter(maybe). Basically a c545 that is built right.
But I'll stick with the c535's for now. I don't need to add more Rf cooking my cells just to clean the air.

If you're talking about the AP200, IP's description is deceptive. It's not as good as the OP's.

Quote :
Filters up to 1,140 SQFT per hour, to exchange 228 SQFT


It's the 228sf that should be used when comparing to the Winix, not the 1,140sf. The square feet number is supposed to be based on about 5 room changes per hour.

Quote :
All air cleaners that are part of the AHAM VerifideĀ® program have been independently tested by a third-party laboratory. Look for the AHAM Verifide seal to find the suggested room size based on 4.8 air changes per hour, and reduction rates of tobacco smoke, dust and pollen (known as clean air delivery rates (CADR)).
Also, Winix does one thing very well, with many items Made in Korea. Instant Brands is now a mass marketer of a huge variety of kitchen items, all made in China.

Quote :
Its subsidiaries were merged and consolidated under the title "Instant Brands". The company is owned by Cornell Capital LLC and headquartered in Downers Grove, Illinois. Instant Brands and its affiliates design, manufacture and market small kitchen appliances and houseware products worldwide.
THEREFORE THIS WINIX IS TWICE AS POWERFUL AS THE INSTANT POT AIR PURIFIER.

I have this model and it's superior to the C545 model. Definitely worth the upgrade if someone is considering this model.

This is what I did. Having multiple purifiers help lessen the frequency I have to dust from once a week to 3 months. I have 6 though, covering 2000 sqft. It also help when cooking. Even with windows open, pm2.5 spikes to 300, but it comes down in 10 minutes with them on full blast. They are very noisy on full blast.

FYI, the C545 uses Filter S, not A. Literally the only model Winix makes that uses a Filter S.

Remove the plastic casing, and it's the same filter. I have both running on the 115115.
