K933454 is an FDA 510(k) clearance for the DYNAMIC GERMICIDAL AIR PURIFICATION SYSTEM. Classified as Purifier, Air, Ultraviolet, Medical (product code FRA), Class II - Special Controls.

Submitted by L&H Airco (Rocklin, US). The FDA issued a Cleared decision on September 16, 1994 after a review of 429 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the General Hospital FDA review panel, regulated under 21 CFR 880.6500 - 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.
