Oxygen Easy C250 filters

The model designation is usually printed on the front cover near the filter access panel. We stock filter sets for Oxygen Easy and X-Air units — C180/C180E, C200/C200E, C250, V200/V200E and V400/V400E/V500/V500E/V600. If the label is worn or missing, measure your existing filter to confirm the right replacement.

We stock the standard Oxygen filter sizes for fast dispatch, with most orders arriving within 1–3 business days anywhere in Germany. Oxygen units are less common here than the mainstream MVHR brands, so keeping the usual classes in stock avoids the delays that come with ordering them in from abroad each time.

Oxygen residential units are generally fitted with M5-class filters, with F7/ePM1 available as an upgrade for households wanting finer particle protection. Both classes are cut to fit the same housing without modification.

Yes — our house brand filters match the originals on every point that matters:

• Manufactured in the EU
• Built to the same ISO 16890 standards as Oxygen's original filters
• Cut to matching tolerances

That combination makes them a reliable, lower-cost alternative for regular replacement.

If an ordered filter doesn't match your Oxygen unit, contact us and we'll exchange it for the correct size or class, provided it's unused and in its original packaging. Sharing your model code or exact filter measurements when ordering is the simplest way to get it right the first time.

Yes. The Oxygen Easy and X-Air C180, C180E, C200, C200E and C250 all share one filter set. The V200 and V200E take their own set, and the V400, V400E, V500, V500E and V600 share another. We stock each of these as a house brand set in two versions: M5+F7 with a fine F7 (ePM1) supply filter, or M5+M5. Oxygen units are less common in Germany than the mainstream MVHR brands, so if you're unsure, measure the old filter in millimetres and send us the dimensions with a photo of the type plate, and we'll confirm the set before you order.
