The Levoit filters are twice as expensive to replace.

  What is that calculation based off of? The article lists the 4 filters as $70 (which I'd assume you would replace all at once). The Levoit uses 1 filter "unit", and filters are $55 for a 2-pack on Amazon ($27.5/ea), or half that if you trust the third-party ones. Levoit recommends to replace the filters every 6-8 months, so you could get 12-16 months of filtration for $55. I can't find any calculation in the article for how long the author estimates their filters would last.

  They don't seem like it. Levoit filters are advertised as lasting 6–8 months and cost $23 each. Meanwhile a set of four filters like the one in the tutorial cost $70 and looking up comparables online at that price point indicates they're good for 3 months. So even if using 4 at a time extends to 12 months, that's still more expensive than the up-to-2 Levoit filters you'd use in that time. I see zero cost benefit here over Levoit -- it seems to be more expensive actually?

    The Levoit mentioned (I have one) is tiny and only good for a small room. The comparison box fan filter can clean a lot more air over the same time period.

      It's good for a large room, not just a small one. I have one too. The CR box is tremendous overkill for something like an apartment. It's gigantic and I don't even know where most people would put one even in a house. But it's also not what the original post was talking about. The original post is a device akin to a Levoit in terms of size and power.
