You can save a lot more than that with aftermarket filters.
This thread is guaranteed to be overrun by the "I only trust authentic filters" crowd who will thumb this down, but the truth is that the composition of HEPA filters isn't some trade secret.
Given equal composition and dimensions, the only characteristic that could possibly differ is the number of pleats one filter has over the other. More pleats offers more surface area and more filtering material, which creates a measurable difference in filtration.
There's some downsides to this, but for the sake of simplicity, that's pretty much all you need to look for when choosing a filter that will perform on par with the official ones.
The C545 (S) filters I get off Amazon come out to about $8 each and I swap them out every 4 months.
As for the carbon filters, those are primarily meant to absorb odor. They do help with pet hair, but you definitely do not need to change them as frequently as they're trying to sell them to you. Just vacuum them out, wash them, and toss them back in once dry.
The YouTube disassembly video is only 15min long, so it's pretty trivial. A smart move is to print screenshots from the video and match up where each screw goes.
A single authentic Winix Filter A set number 115115 for the older unit C535 is $36.70 shipped and sold by Amazon or $73.40 for two sets compared to $65 for the pair of sets at Costco. Free delivery for me tomorrow vs a week from Costco.

I'd rather save the ~$10 bucks, after all, that is whole purpose of this site.

You can get generic filters a lot cheaper. I also have 5 of these machines from Costco that I've bought over the past 4 years and all of them develop motor whine. I'd stay away unless they've fixed the issue with new ones.

So you're justifying $8+ for expedited shipping?
That's fair, but if you don't *need* to replace them within a week, then it appears that your decision is driven by the need for instant gratification.
Nothing wrong with that as it's your choice, but your argument breaks down for the target audience. $13% premium for expedited shipping is a bit much.

You can fix the motor whine by lubricating them.

I did try knockoff filters from amazon and they had such an awful musty sour smell.
The replacement filters number for my C535 has always been 115115, but this link shows 113151. I don't know what the difference is or if it matters. It could be slightly different to also accommodate the C909.

For lube, Super Lube worked great.

Which ones do you order?
Search for the purifier brand and the original part number or the filter type.
The 545 uses S filters.
Count the pleats on the original filter and compare to the one pictured. Obviously, check the reviews.
SD removes Amazon links that fall under whatever criteria they have set, as well as other shady stuff, so I can't post one directly.

Can you link the ones you use?

That might be the plastic they were wrapped in, or possibly a lack thereof if you ordered during a humid season?
The ones I've used all come individually wrapped.
When it's time for a change, I put the purifier on turbo for at least an hour to make sure it's working properly.
Another possibility is that you're smelling the ionizer, perhaps?
