I have a bunch of air filters (I live in the bay area during fire season).
Coway Air Mega
Coway Mighty
Blue Air
Medify Air
They're basically all equivalent and they all work.
The reason I like the Medifyair is because it can move the largest volume of air relative to those so it can clear a space quickly (and quietly). I also think it looks nice (though it is huge).
Of the rest, the Blue Air uses weird custom filters which I think cost a little more (though I haven't had to replace them yet). The Coway Mighty is also pretty small and mostly for a tiny room.
Relatedly, if you're interested in sensors I think the TemTop sensors are the best (I've tried a bunch of different ones, and a lot of them suck).
Wirecutter has a review of one of the Medifyair models. They don't recommend it because it's too big, and overkill for their test apartment in New York City. It had the highest CADR in their testing.
For a modest house in the Bay Area during fire season, we needed a high MERV furnace filter and also two filters similar to their recommended models, so I moved up to the Medifyair. It arrived after the last fires, but it seems to work extremely well.
That's one example of a Wirecutter recommendation that goes against the prevailing wisdom. There are probably others, too -- but that doesn't necessarily mean all their reviews are somehow bad or tainted. You can find recommendations from Consumer Reports that run against the prevailing wisdom, too; I know I'm not alone in having thought in the past that there were some categories of products they were great with and other categories of products they were... not so great with.
I know the "you can never trust anyone who has affiliation links" argument, but if we follow that to its logical conclusion, Wirecutter should be strongly biased toward picks that give them the most money for referrals, and that's not really backed up by their choices. They pick cheaper choices pretty frequently, and it's possible to find picks where there's no apparent affiliate link at all, e.g., their pick for best "high-performance" subwoofer. One can posit, as was done in the thread you linked, that there might be deals directly with manufacturers that we don't know about, but "we can't be sure they're being underhanded without us knowing" doesn't actually get us anywhere useful -- the same could obviously be said about anyone, including CR.
In the review business it's better to be playing the long-term game if you're building a real audience. In Wirecutter's case their long term advantage is to make good reviews without regard to the affiliate payment.
There are already thousands of other websites that are just disguised ads. Wirecutter's differentiating features is that they don't do that.
They still have some reviews I think are pretty mediocre or products they chose that I think are bad, but generally I think they're worth looking at.
