Head to head
When it is down to two, a spec sheet is not enough — you need to know which one wins on the thing you care about. Each comparison goes criterion by criterion and ends with two plain sentences: choose this one if…, choose that one if…
How these comparisons are made
How do you decide which one wins?
Criterion by criterion, against documented figures, and we say when a criterion is too close to call rather than inventing a winner. Where one unit has an AHAM Verifide CADR and the other has only the brand’s own number, that difference in evidence is itself part of the comparison — they are not the same kind of claim and we do not line them up as if they were.
Why compare these two in particular?
Because they are the pairs people actually weigh against each other, usually similar coverage at a similar price. We do not generate every possible combination: a comparison between two units nobody cross-shops is a page written for a search engine rather than for a reader.
