K211507 is an FDA 510(k) clearance for the Airdog X5 Recirculating Air Cleaner (model KJ300F-X5). Classified as Cleaner, Air, Medical Recirculating (product code FRF), Class II - Special Controls.

Submitted by Beiang Air Tech , Ltd. (Suzhou, CN). The FDA issued a Cleared decision on November 22, 2022 after a review of 557 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the General Hospital FDA review panel, regulated under 21 CFR 880.5045 - the FDA general hospital device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind General Hospital submissions.
