PureVent 5L Medical-Grade Pet Oxygen Concentrator

Sale price$850.00

The PureVent 5L Oxygen Concentrator plugs into a wall outlet (120V) and concentrates oxygen from room air, providing high purity oxygen gas (>90%). The Oxygen Concentrator provides continuous flow oxygen (does not need to be refilled) and is recommended for pets requiring extended oxygen therapy. Use the Oxygen Concentrator with a PureVent Pet Oxygen Mask or an Oxygen Cage.

The PureVent 5L Oxygen Concentrator is intended to be used with the Medium PureVent Pet Oxygen Chamber, to achieve appropriate oxygen levels and mitigate carbon dioxide, heat, and humidity for your pet. 


Why Pet Parents Invest in Medical-Grade

Non-Medical Concentrators

(Concentrators you find on Amazon without an RX)

  • Drops to 30-55% purity at higher flow rates
  • Output fluctuates unpredictably
  • Venturi Kit can't deliver accurate oxygen levels—diluted oxygen becomes unreliable
  • Not validated by veterinary standards
  • Insurance companies won't cover them

Your vet prescribes a specific oxygen level to treat your pet. Medical-grade equipment ensures that prescription actually works. Non-medical concentrators can't guarantee it.

O₂ Normal

This will display when your machine is completely turned on, oxygen is flowing and operating as normal.

Session time

This keeps track of your session time. Average oxygen chamber sessions can last anywhere from 20 minutes to 2+ hours.

O₂ Saturation

This number will fluctuate. An ideal range is anywhere between 90% and 95%. Altitude, air flow and other variables will fluctuate your number - this is completely normal.

LPM (liters per minute)

This is your liters per minute. When using a medium PureVent oxygen chamber, you will always set this number to 5.0. If using with a mask, you may set this lower according to your veterinarian's guidance.

LPM Dial

This is how you will set your liters per minute 1.0-5.0. You will always set this to 5.0 when using the medium PureVent chamber.

Display Light

Turn your screen display light on and off as needed.

Timer

Add a timer to your session. It's important to note that if setting a timer, the oxygen will turn off when it's ended and you should not leave your pet inside. Tip: set a timer on your phone and always stay with your pet

Audio Accessibility

Our audio accessibility feature will verbally tell you settings out loud. You can turn this setting on or off.

Oxygen Port

This is where you will hook up one end of your oxygen tubing (the other end will be connected to your chamber or mask).

On/Off Display

This is your on/off button for your display. It's important to note that you have a primary on/off switch for the machine on the back.

Frequently asked questions

Below are the questions we hear most from pet parents and veterinarians. For anything else, give us a call or chat with a Pawprint representative.

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.
