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.
What happens if an Oxygen filter I order turns out not to fit my unit?


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.
How fast do you deliver Oxygen ventilation filters within the Baltic region?


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.
Are house brand filters a good fit for Oxygen units?


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.
What filter class does Oxygen use as standard?


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.
How do I find the right filter for my Oxygen ventilation unit?


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.
