I've gotten good recommendations from Wirecutter, but also very bad ones. I bought their recommended coffee machine, and it's $200, and no better than the $30 Mr. Coffee it replaced (except, I guess, in the referral fee they get).
They also recommend an air purifier by Levoit, which performed demonstrably worse than a box fan with a HEPA filter bungee corded on to it[1]. In fairness, Wirecutter recommended a cheaper model, but is that model going to perform better than the more expensive one in the same line? In any case, it's still not cheaper than a box fan and a HEPA filter, which ought to be the baseline you'd test against if you were providing value to your readers.
