Pre-filtration for AirPack4 heat recovery ventilators

This set of two pre-filters, known as Prefilter 09, is designed to work in conjunction with CleanPad Pure 09 filters in Thessla Green AirPack4 heat recovery ventilators. Their purpose is to protect the main filters from larger contaminants, thereby extending the lifespan of the entire filtration system and reducing the frequency of costly main filter replacements. This simple solution ensures high indoor air quality while simultaneously lowering operational costs.

Design and Application

Prefilter 09 filters are made from durable nonwoven fabric that effectively captures dust, pollen, insects, and other larger particles. Installation is extremely simple—the filters are attached via Velcro directly onto the CleanPad Pure 09 filters. This mounting method enables quick and tool-free replacement. These pre-filters are specifically designed for AirPack4 models 300, 400, and 500 with H-type duct connections, ensuring optimal ventilation performance and user comfort.

Benefits of Using Prefilter 09

• Protection of main filters: By capturing larger contaminants, pre-filters significantly extend the lifespan of the more expensive CleanPad Pure 09 filters.
• Simple installation: Velcro mounting system allows for fast and easy replacement without tools.
• Compatibility: Specifically engineered for Thessla Green AirPack4 models 300/400/500 with H-type duct connections.
• Efficiency: Made from high-quality nonwoven fabric, effectively capturing large particulate contaminants.
• Cost-effectiveness: Reduced frequency of main filter replacements leads to lower overall ventilation system operating costs.
• Air quality maintenance: By safeguarding the main filters, pre-filters help maintain high-quality filtered air within indoor spaces.
