The only real issue is that it doesn't automatically search for a network after power loss, which apparently a lot of people couldn't figure out?

You just have to hit the wireless connection button once for it to reconnect.

My issue with a refurb is my older (4 or 5 year old running constantly) model has developed a high pitched coil whine. I feel like I'd rather get a new one next time it hits Costco for $99

Did they fix the WiFi board issues ?
Mine works and I got two

Super easy to setup with login to Winix wifi app

I have asus mesh wifi without smart connect so could be end user error

I've been waiting for one to go on sale at Costco for $99, which comes with an extra filter, but I don't know if they still do those sales, it seems like it's been a long time.

Um, what is plasmawave and what is it supposed to do?
It pretty much reads Air quality and gives you visual feedback based on the color of the indicator

Neat but not sure if necessary; it's ideal if you introduce high allergens suddenly like come in from mowing or cooking something that will get picked up by this and so it will ramp up its fan automatically to compensate

Don't buy refurbs from this brand. 2 units started making loud fan noises while my 4 bought new are still running! Also read another comment stating the same last time so I want to share.

Quote from Deal-R-Dash :
Totally this ^^^^^. Three out of the four refurbs I purchased from Woot did it in year 2. I even tore one of them down and added some 3-in-1 oil to one side of the fan motor and it helped for a whopping 5 minutes. I also reached out to Winix support to get a repair estimate and they told me they don't work on them or sell parts and I should hire a local electrician to repair it lol! Fortunately, my credit card extended warranty took care of 3 out of 4 of them. The only way I would buy Winix again is from Costco and having the return policy. I'm not as big of a fan of this brand of air filters as a result.
I'm sorry but this made me laugh. Not laughing at you at all for being proactive and trying to save more Chinese crap from ending up in the landfill, but laughing at wi nix response to your repair enquiry…."call a local Electrician". Ha, I have no idea why I find it so funny, but it is. What a Sh*t company, with sh*t customer service. Pay a minimum of $100 to have some guy who wires houses up, tell you that you're basically a moron for calling him to fix your highly specific electronic air purifier. I mean it's pure electrons and circuits right? Why not call an electrician? Heck, why not recommend a circuit board designers assistance or someone in the EPA who specializes in Air purification data to fix a $70 air purifier? It's just all so stupid.

We as consumers need to speak out loudly with our purchasing power against garbage companies like this now, before everything becomes one giant Corporation and we no longer have any choices. Everyone blames all of our current perceived problems to high inflation, but are totally blind to all the Corporate consolidation that has happened over the last 30yrs, and the possibility that price fixing, collusion, and Corporate profit taking might have more to do with it than any singular political party or individual.

This gets posted every so often and the consensus is that you're likely better off buying from costco for $99 if you have a membership. You get extra filters and the costco guarantee.
Buy from woot if you want to save money, have less filters and possibly have to fix it a few years from now when it starts to whine

That's not at all what PlasmaWave is. You're describing the automatic air quality sensor, which has nothing to do with PlasmaWave. I leave PlasmaWave off, and the air quality sensor still lights up blue / yellow / red.

As I understand it, PlasmaWave is an ionizer. The concern is that it may produce ozone.

Consider these disposable after 2 years or so. Almost all get a whine after significant use and needs replacement.

I put one of these in a tiny 10x8 room (serves as a home office) that has a single door and window. Everything still gets covered with dust. Filters are expensive so I just unplugged it and it's waiting to go to donation center.

I bought my refurb last July direct from Winix for $70 after the east coast got smoked by the Canadian wildfires. It came in a brown cardboard box but mine looked essentially new. I believe Woot units are shipped by Winix anyway (like their Dyson sale).

It is on almost 24/7 in Auto mode and it stays in Low speed 99+% of the time (probably a few minutes per day when it spins up after detecting fart, the occasional toaster/cooking smoke or unknown reason).

My pre-filter and the main pleated filter never get much buildup (unlike Amazon customer photos of caked dirt), but I have no pet or carpet and I keep the purifier 6 inches off the floor (no point filtering out kicked up bulk dust when a vacuum cleaner or sweeper does the job much cheaper). Per the app, filter is now at 7% so I guess it is partly a 1-year countdown timer to replace it regardless of air quality or how little it appears to pick up. I never changed the 3-month carbon foam filter so I still have 3 new ones (it came with 4). The top of the unit has a film of dust after a while, like the rest of the room and floor, so don't expect it will remove a lot of airborne dust unless you run it at higher speeds.

The app and Wi-Fi aren't essential (for me) since Auto mode works for me, and I don't see the need to schedule times, turn on/off or change speeds, check outside (EPA data) or indoor (sensor) AQI history or operating mode (on/off, speed. It can be useful to check and change the operating mode (on/off, auto/L/M/H/sleep speed) especially if the purifier is not in your vicinity.

Low speed is barely perceptible noise-wise even when nearby and only uses 5W which is surprisingly efficient for such a big unit (I own smaller desktop cylinder purifier models that use 5-10W in low, move much less air and noisier). It is cheap to run at 0.005 kW * 16.1c kW/hr national average rate * 24 * 365 = $7 per year, double or triple it if you live in NY, CA, HI etc. Sleep mode, which I never use, is super-slow speed, dims the LEDs and uses 3W. Needless to say I'll only buy air purifiers with AQ sensor and auto speed mode.

Winix had a major sale last month, including the C535 for $105/$95 new/refurb, and the refurb AM80 for $100 with washable AOC filter that some people recommend, but most items have sold out.

I'm almost there too, and I feel like non of them work to "purify" air other than just collecting the dust, non of them can reduce smell or give "hmmm fresh air" sense.

These are pretty decent in my experience but I prefer to buy them directly from Winix [winixamerica.com] for $69.99 when they go on sale; which is often.

The air quality sensor works great (will detect cooking orders, alcohol based spray cleaners remarkably well for example) and third party replacement filters can be easily found on Amazon pretty cheap.

The only issue that I have with them is that if the power goes out even briefly these units will default to off and will not turn on automatically. I've had instances where the my C545s have been off for weeks without me being aware due to a very minor power outage that lasted less than 5 seconds.

Overall I would dare say that refurbished C545s are the best bargain/overall bang for buck you can get currently. Nothing in their price range has come close to what C545s offer IMO; at least I have not found anything that can compare price and feature wise...

I have had one of these for years with no issue. Has anyone who owns one tried any of the generic filters available for these? If so, which ones? I have always ordered the official Winix ones, but they are much more expensive.
Pretty much the same. I bought mine from Woot! in August of 2021.

No whine, but I've always ran it on Auto & turn it off at night with the app schedule. Wifi does refuse to reconnect about every few months which can be aggravating, but it has never failed to reconnect after some prodding.

The biggest issue I see with these is the refurbished price today is almost exactly the same as it was in 2021.
