PureVent 5L Medical-Grade Pet Oxygen Concentrator – Continuous Oxygen Therapy for Dogs Cats and Pets

Medical-grade concentrators are FDA-regulated and consistently produce >90% pure oxygen across their full flow range. Non-medical-grade units (often labeled "pet" or "wellness" concentrators) aren't held to the same standards — many drop to 30–55% oxygen at higher flow rates, barely above room air.For a pet in respiratory distress, that difference matters.

Medical-grade equipment delivers a true therapeutic dose, includes built-in safety alarms, matches what your vet uses in the clinic, and qualifies for pet insurance reimbursement because it requires a prescription. Both PureVent concentrators (5L and 10L) are medical-grade.

It comes down to your pet's size and which chamber you're using:

- The PureVent 5L pairs with the Medium PureVent Oxygen Chamber and is ideal for small to mid-size pets (up to roughly 30 lbs).

- The PureVent 10L pairs with the Large PureVent Oxygen Chamber and is needed for larger dogs or any setup requiring 6+ LPM of flow.

If you're using a mask only (not a chamber), the 5L is plenty for most pets. When in doubt, give us a call — we'll help match you to the right setup.

Yes. After checkout, we'll reach out to collect your vet's information or prescription. Orders typically ship 24–48 hours after we validate it.

Vets commonly prescribe at-home oxygen for congestive heart failure, pulmonary hypertension, collapsing trachea, laryngeal paralysis, pneumonia, feline asthma, recovery from surgery or smoke inhalation, brachycephalic breathing issues, and end-of-life comfort care.

Many plans reimburse for medical-grade oxygen equipment prescribed by a licensed vet. Because our concentrators require an Rx, you'll have the documentation most insurers ask for. Coverage varies — check with your provider, and we can supply any paperwork you need.

It depends on your vet's instructions. Acute distress is typically 15–30 minute sessions; chronic conditions like CHF often involve 1–4 hour sessions, sometimes overnight. Always follow your vet's prescribed flow rate and duration.

No. It pulls oxygen from room air continuously — no tanks to swap or refill. Rated up to 30,000 hours of use.

Under 48 dBA — quieter than a typical conversation, closer to a refrigerator's hum. Most pets settle in quickly, and the 5L is one of the quietest medical-grade concentrators on the market.

It plugs into a standard 120V outlet and draws roughly 350 watts during operation — comparable to a desktop computer. No special wiring needed.

Very little. Rinse the pre-mesh filter (back of unit) as needed and let it air-dry. Replace the box filter at 5,000 hours of use or once a year. Wipe down the exterior occasionally. The hour-meter on the side tracks usage.
