We’ve gathered answers to the most common questions about our products and services. If you can’t find an answer here, please contact us directly.

How do I identify my exact Paul model (e.g. Novus, Focus, Climos)?

Plus icon Close icon

Two pieces of information on the unit's front panel confirm your exact Paul model:

  • The series name, such as Novus or Focus
  • The longer alphanumeric model code, which specifies airflow capacity

Both help match you to the correct filter set, especially where multiple airflow variants share a series name.

What filter class is recommended for Paul units?

Plus icon Close icon

It depends on the model. The Paul filter sets we stock come in these combinations:

  • Novus 300/450 and Focus 200 — G4+G4, or G4+F7 with a fine F7 (ePM1) supply filter
  • Climos (F) 200 — M5+M5, or M5+F7

Because Passive House buildings get all their fresh air through the MVHR unit, the version with the F7 supply filter is usually the better choice for indoor air quality.

Why is Paul associated with Passive House ventilation specifically?

Plus icon Close icon

Paul Wärmerückgewinnung is a German pioneer of ventilation systems designed for Passive House and low-energy buildings, with several unit series built around very high heat-recovery efficiency. Depending on the model, Paul units use G4, M5 and F7 filters.

Do Paul Novus and Focus models use the same filter size?

Plus icon Close icon

No. The Focus 200 takes its own filter size, while the Novus 300 and Novus 450 share one set. The Climos (F) 200 uses a different size again. Check the series name and model number on the unit before ordering, then choose the G4+G4 or G4+F7 version (M5+M5 or M5+F7 for Climos).

Our Paul unit is in a near-zero-energy new build — is F7 enough, or should we go higher?

Plus icon Close icon

For most households F7 is enough, and changing it on time matters more than anything else. In an airtight, near-zero-energy home practically all the fresh air arrives through the ventilation unit, so the supply filter is the only barrier between outdoor air and your living rooms — which is an argument for keeping it fresh. A properly sized F7/ePM1 filter, replaced on schedule, removes the large majority of pollen and fine dust. F7 is also the finest class we stock for Paul units: choose the G4+F7 set for the Novus 300/450 and Focus 200, and the M5+F7 set for the Climos (F) 200. If symptoms persist, check the filters more often during pollen season rather than looking for a denser filter, which would raise air resistance and fan load.

How often should Paul filters be changed in a Passive House?

Plus icon Close icon

Check them every 3 months and replace them at least every 6 months. In a Passive House the MVHR unit supplies all the fresh air, so a clogged filter shows up quickly as stuffier air and more fan noise. Change the supply filter sooner during pollen season or if you live near a busy road, and keep a spare set at home so you never run the unit on saturated filters.
