Oxygen Easy V400 Filters

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

We stock Oxygen filters for fast dispatch across the Baltic region, with most orders arriving within a few business days. Given how widely Oxygen units are installed locally, keeping common filter classes in stock helps avoid the delays that come with ordering from further afield.

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.

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.

Oxygen units are most common across the Baltic region, and the model designation is typically printed on the front cover near the filter access panel. If it's worn or missing, measuring your existing filter is the most reliable way to confirm the right replacement.
