Oxygen Easy 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.

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.

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.

We stock the standard Oxygen filter sizes for fast dispatch, with in-stock orders leaving within 24 to 48 hours and arriving in about 3 to 4 business days. Oxygen units are less common in Austria 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.

Yes, briefly but measurably. When Saharan dust reaches Austria it puts a large amount of very fine mineral dust into the outdoor air for several days at a time, and the outdoor-air filter is what catches it before it reaches your rooms. A single episode will not ruin a filter, but several in one season noticeably shorten its life compared with a quiet year. The practical response is to look at the filter after a dust event rather than waiting for the next scheduled check — if it has visibly changed colour since the last inspection, that is your answer. It is another argument for keeping a spare set at home.
