PureFlow 200
EPP Filter Box
Advanced air filtration for every space. Designed for use in ventilation systems with or without heat recovery. Manufactured from expanded polypropylene (EPP) for outstanding thermal and sound insulation without the risk of condensation.
- ✔ Compatible with DN200 and DN160 (8"/6") duct connections
- ✔ Holds up to three filters simultaneously
- ✔ Zero thermal bridging (eliminates condensation)
- ✔ Complies with ISO 16890 standards
Engineered for Challenging Climates
Whether facing the humid summers of Florida or the freezing winters of Northern Europe, the PureFlow 200 eliminates the thermal bridging and internal condensation that plague standard metal filter boxes.
Stop Filter Mold Before It Starts
Traditional metal filter boxes act as thermal bridges, "sweating" when temperatures clash. This ruins filters and breeds mold. The PureFlow 200’s high-density EPP casing provides seamless insulation, eliminating internal condensation and keeping your filters bone-dry.
Coastal & Tropical Ready
Perfect for the USA and Southern Europe. When handling cold AC air in warm, humid mechanical rooms, standard metal boxes sweat profusely. Our EPP housing prevents surface condensation (dew point) even in relative humidity up to 90%.
3-Stage Flexible Filtration
Combine ISO Coarse 75% for large particles, ePM1 60% for fine dust, and Carbon 250g for odors and VOCs. Ideal for residential, healthcare, and indoor farming.
The Impact of Climate on Filter Pressure Drop
Air density changes dramatically with temperature and humidity. Cold, dense winter air requires more fan power to push through filters, while warm air lowers resistance. Understanding this dynamic is crucial for correctly positioning the PureFlow 200 in your HVAC system across different global climates.

Winter Pre-Filtration
Placing the filter in the fresh air intake at -20 °C means the fan overcomes a slightly higher pressure drop (+16%). However, the base resistance of the ISO Coarse filter is so low (15 Pa) that the impact on the system is negligible.
Post-Heater Placement
For absolute maximum efficiency in severe winter climates, installing the PureFlow 200 after a pre-heater normalizes the air density to standard conditions, maintaining the guaranteed 15 Pa baseline pressure drop.
Hot & Tropical Climates
Hot and humid air is physically lighter. Operating in +35 °C environments naturally reduces aerodynamic resistance through the filter media, further easing the load on your ventilation fans and saving energy.
