Honeywell

It stands out for 320 smoke CADR is genuine large-room capability at a price that frequently dips under 200 dollars and exposed filter design without a plastic cage puts more usable media in the airstream per dollar.

  • 320 smoke CADR covers ~465 sq ft
  • True HEPA at 99.97% capture
  • Turbo Clean rapid-knockdown setting
  • Exposed pleated filter, no plastic cage
  • 3 fan speeds plus auto and sleep

Pros

  • 320 smoke CADR is genuine large-room capability at a price that frequently dips under 200 dollars
  • Exposed filter design without a plastic cage puts more usable media in the airstream per dollar
  • True HEPA rating is documented on spec, not marketed loosely as HEPA-type
  • Filters are widely stocked both genuine and third-party, keeping five-year cost predictable
  • 34,000 ratings support consistent long-term performance at this CADR tier

Cons

  • Louder than the Coway or Levoit at equivalent output, especially at speed three
  • No washable pre-filter, so hair and debris load directly onto the HEPA media
  • Boxier housing feels less refined than the Coway's
