1-2 of 2The Wolf CWL-F-150 takes a 175x143mm filter set, available as standard G4+G4 or an upgraded G4+F7 pairing.
Wolf CWL-F-150 Filter Set
- G4+G4 (standard) – 175x143x5mm on both sides. From €8.90.
- G4+F7 (upgrade) – 175x143x5mm extract, 164x132x20mm supply. From €25.91.
G4+G4 Standard vs. G4+F7 Upgrade
G4+G4 covers general dust, pollen and plant debris at the lowest running cost. The G4+F7 upgrade swaps the supply filter for a finer, deeper F7 panel, adding protection against fine pollen, pet dander, bacteria and smog – a sensible step up for allergy-sensitive households.
Don’t Confuse F-150 with F/T-300
The “CWL-F-150” and “CWL-F/T-300” names share the “F” prefix but refer to different units with different filter sizes (175x143mm vs. 245x177mm). Double-check your unit’s label before ordering, since the naming similarity is an easy mix-up.

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.
Can I order a full year’s supply of Wolf CWL filters together, especially if paired with Wolf heating equipment?
Yes, ordering a full year's worth of CWL filter sets in one purchase is common, particularly for households already managing a paired Wolf heating system on a similar service schedule. Multi-set orders are typically priced lower per filter than buying individually.
Do smaller and larger Wolf CWL units use the same filter?
No — filter sizes depend on the model. The CWL-300 and CWL-400 Excellent share one set, while the CWL-180, CWL-F-150 and CWL-F/T-300 each take their own. Confirm your exact CWL variant on the unit's label before ordering, since the series name alone doesn't guarantee a matching size.
Does pairing a Wolf CWL unit with Wolf heating affect filter maintenance?
The ventilation and heating functions operate independently in terms of filter maintenance, but combined Wolf systems often run ventilation more consistently to support overall climate control, so it's worth checking CWL filters on the shorter end of the standard 3–6 month interval.
What filter class is standard for Wolf CWL units?
It depends on the model. For each CWL unit we stock two versions:
- CWL-300/400 Excellent — G3+G3, or G3+F7
- CWL-180 Excellent — G3+G3, or G3+M6
- CWL-F-150 and CWL-F/T-300 Excellent — G4+G4, or G4+F7
The version with the finer supply filter (F7 or M6) is the better choice for pollen and fine dust.
Which Wolf ventilation units does your filter catalogue cover?
We supply filter sets for Wolf's CWL Excellent range — CWL-180, CWL-300/400, CWL-F-150 and CWL-F/T-300 Excellent — the German manufacturer's main residential MVHR line, often installed alongside Wolf heating systems. The model name is printed on the unit's label.
