Fresh Air System and Air Conditioner Odor Removal Filter

The Jyntrel fresh air / fresh air conditioning odor removal filter is a composite filter combining polypropylene (PP) media with modified activated carbon. It captures fine particulate matter such as PM2.5 and pollen while adsorbing formaldehyde, TVOC, and other odorous gases. It is designed for residential wall-mounted fresh air units, cabinet fresh air conditioners, and central HVAC systems in homes and commercial buildings. Jyntrel manufactures this filter with customizable efficiency from F7 to H13 and full OEM/ODM support.

Operating Conditions and Airflow Path

In a fresh air system, outdoor air is drawn through the filter before entering the ductwork or the conditioned space. The filter therefore sees continuous airflow with varying velocity depending on the fan speed and system design. The composite PP layer provides mechanical filtration of particles, while the activated carbon layer adsorbs gaseous contaminants as the air passes through. The filter is typically installed in a frame or cassette that holds it perpendicular to the airflow, ensuring even loading across the media face.

Air velocity affects both pressure drop and capture efficiency. At higher velocities, the filter may exhibit increased resistance, which can influence fan energy consumption. Jyntrel tests each filter design for airflow resistance and efficiency to ensure stable performance across the intended operating range. The filter is not intended for use in environments with excessive moisture or where the air contains solvents that could degrade the activated carbon.

Core Performance

The filter is available in efficiency classes from F7/F8/F9 (medium efficiency) up to H11/H12/H13 (HEPA) for particulate removal. The activated carbon layer uses high iodine value carbon to provide deep adsorption of formaldehyde, TVOC, ammonia, and hydrogen sulfide. This dual-function design allows a single filter to address both particulate and gaseous contaminants, simplifying system design and maintenance.

Performance data is verified in Jyntrel's CNAS-accredited laboratory, where filters undergo rigorous testing for airflow resistance and filtration efficiency before shipment. The filter media and activated carbon are selected to meet REACH and RoHS requirements, and compliance documentation is available upon request.

Selection and Customisation: the Data We Need

To recommend the appropriate filter, Jyntrel needs specific information about your system and requirements. Please provide the following:

• Device or system model and the available space for the filter
• Required filter dimensions or a drawing of the installation area
• Airflow rate (m³/h) and expected face velocity
• Operating conditions: temperature, humidity, and presence of specific contaminants
• Desired filtration efficiency (e.g., F7, H11) and odor removal targets
• Estimated annual quantity and any packaging or branding requirements

With these details, Jyntrel can propose a filter configuration that balances efficiency, pressure drop, and service life. Customisation options include flat panel, V-bank, or composite designs, as well as choice of frame material and activated carbon type. Jyntrel has developed over 1,000 filtration solutions and can adapt existing designs or create new tooling as needed.

Parameters

Typical Applications

This filter is used in residential wall-mounted fresh air units, where it helps maintain indoor air quality by removing particles and odors from incoming outdoor air. In cabinet fresh air conditioners, it protects the heat exchanger and improves the quality of conditioned air. For residential and commercial central fresh air systems, the filter can be specified in various efficiency grades to meet different indoor air quality targets. The dual-function design is particularly beneficial in urban areas where outdoor air contains both particulate matter and gaseous pollutants.
