Paul HRV Filters
Paul HRV filters are exact-fit replacement filter sets for selected Paul heat recovery units. Designed for a secure fit, these filters help maintain stable airflow, protect the heat exchanger, and support cleaner indoor air.
Our Paul-compatible filters are made in Lithuania and supplied as practical filter sets for supply and extract air. Browse all HRV / recuperator filters, see delivery & shipping, or contact us if you need help choosing the right set.
Paul filters for Climos, Focus, Iso-Preheater and Novus units
This category currently includes replacement filters for models such as Paul Climos F200, Paul Focus (F) 200, Paul Iso-Preheater DN 160, and Paul Novus 300 / 450F. Always match the exact model and filter dimensions before ordering.
Two-filter sets for balanced airflow
Most sets include two filters: one for supply air and one for extract air. Correctly fitted filters help reduce bypass air, support stable ventilation performance, and keep the system cleaner over time.
Why exact dimensions matter
The most common reason replacement filters underperform is incorrect sizing. A filter that is too small may allow unfiltered air to pass around the frame, while a filter that is too large may not fit or seal properly. Before ordering, compare the dimensions of your current filters and confirm the exact unit model.
How often should you replace Paul HRV filters?
A practical replacement interval is 2–3 times per year. In dusty environments or near heavy traffic, more frequent replacement may help maintain cleaner air and more stable airflow.
