The device is intended for home use only. ## Device Story Airsonett AIR-4 is a mobile air filtration system using Temperature controlled Laminar Airflow (TLA) technology. Device draws ambient room air through a HEPA filter via a blower; filtered air is cooled slightly below ambient temperature. Cooled air, being denser, descends via gravity in a non-turbulent laminar stream from an adjustable nozzle, displacing allergens in the patient's breathing zone during sleep. Warm air byproduct is exhausted separately to manage internal heat. System is microprocessor-controlled, monitoring temperatures, thermoelectric modules, and fan performance. Intended for home use by patients to reduce inhalant allergen exposure. Healthcare providers use the device to support allergen management; output is a localized clean air zone. Benefits include reduced nocturnal allergen load. ## Clinical Evidence Bench testing only. Testing verified filtration efficiency (≥99.5% for particles ≥0.5µm), clean zone stability, and temperature differential (≥0.75°C) between supply and ambient air. Performance confirmed compliance with Class 1000 (FED STD 209E) and Class 6 (ISO 14644-1) standards. ## Technological Characteristics Mobile air cleaner; HEPA filtration; thermoelectric cooling/heating; adjustable air guidance arm. Microprocessor-controlled system; sensors for temperature monitoring. Power: 115-230V (50-60Hz). Standards: IEC 60601-1, IEC 60601-1-2. Airflow: ≥120 m³/h (cool side), ~80 m³/h (warm side). ## Regulatory Identification A medical recirculating air cleaner is a device used to remove particles from the air for medical purposes. The device may function by electrostatic precipitation or filtration. ## Predicate Devices - Airsonett Airshower Air-3 ([K081062](/device/K081062.md)) - BREATHE EASY (Models AD and CD) by RespirAid Ltd ([K981841](/device/K981841.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The air from the room enters the Airsonett and passes a filter that captures allergens and other particles. The filtered air is cooled to slightly below the ambient room temperature and is supplied with a low velocity from the air supply nozzle. Since the filtered air is slightly cooler, and therefore heavier than the surrounding air, the filtered air will descend slowly from the air supply nozzle by means of gravity in a laminar manner (non-turbulent). This descending colder air counteracts the body convection, displaces the allergen load in the breathing zone and thus dramatically reduces the level of inhalant allergens for the patient all through the night. Air is drawn in through the air intake at the floor level and through the HEPA filter. A silent Blower (fan) brings airflow through the filter. The air is directed through the Cooler/Heater and divided into a cool respectively warm air flow. The cool air flow is directed through the Air guidance arm (neck) and out through the Airshower (Air Supply Nozzle). The Airshower can be altered in height, by adding/removing and combining the neck parts, to adapt to different types of environments. The warm air flow is directed to the Warm air outlet. On its way to the outlet the air flow passes the electronics and transports away the extra heat produced by the electronics. {1}------------------------------------------------ ### Airsonett AIRSONETT AB, Metallgatan, SE-262 72 Ängelholm, Sweden Airsonett is based on a microprocessor controlled supervisory system. This system controls the device behaviour by measuring temperatures, controlling thermoelectric modules and fan unit, monitoring user interaction as well as management of internal timers to keep track of the total ontime for the system and time since last filter change. The control functions (Front Panel Board) and power distribution function (Power Electronics Board) are allocated on two separate circuit boards, Intended Use: The Airsonett AIR-4 is a Mobile Air Cleaner intended to be used to remove particles from the air for medical purposes. The device is intended for home use only. | Element of
