G2 Return Air Filter for 250X215x5MM DFONE
Product description
G2 Filter 218×23 mm – DFONE
Basic air filter developed for mechanical ventilation with heat recovery (MVHR) systems, compatible with DF ONE units. Classified as G2 under ISO 16890, this filter acts as a primary barrier to capture larger particles from incoming air, protecting the system and improving indoor air quality by trapping dust, fibers and visible contaminants.
What this filter does
Protects your DF ONE unit: prevents dust and large particles from reaching internal components.
Improves air cleanliness: captures visible dust, lint, fibers and coarse particles in the airflow.
Reduces maintenance frequency: by capturing large particles first, it lowers the load on subsequent filters and helps extend service intervals.
