How we match

We keep only air purifiers that meet your requirements (Room size and Budget), then rank them by the extras you asked for. An air purifier only gets credit for a feature when its maker states it; "not stated" never counts as yes. Among equals, air purifiers priced in the budget band you chose come first (with no limit, the air purifiers above our top budget), then air purifiers whose makers state more of what you asked about, then the lower price on the maker's own store, then a fixed catalogue order. We compare one air purifier per brand: each brand's highest-ranked match.
