Why Pet Owners Invest in Medical-Grade
Medical-Grade (PureVent 5L)
Consistent >90% pure oxygen
- Delivers consistent >90% pure oxygen across all flow rates
- FDA-regulated and clinically validated
- Venturi Kit delivers accurate vet-prescribed oxygen levels (25-60%)
- Same equipment veterinarians trust in their clinics
- Qualifies for pet insurance coverage (with prescription)
Non-Medical Concentrators
Inconsistent output
- Drops to 30-55% purity at higher flow rates (dangerous for pets)
- 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.
The same equipment used in veterinary hospitals.
One Investment. Accuracy you can trust. Peace of Mind.
At-Home Setup

Cost Comparison at a Glance
The payoff: equipment pays for itself in 1–2 hospital visits
One emergency oxygen event at the vet covers your entire at-home investment. After that, you have medical-grade equipment on hand whenever your pet needs it—and your vet's prescription actually works, consistently.

No, you do not need to refill an Oxygen Concentrator. It constantly generates oxygen from the room air, so you never need to worry about running out of oxygen.
These machines are very easy to use and require little maintenance. Other than the occasional wipe-down to remove excess dust and debris, there are two filters within the concentrator. The first filter you’ll see on the back is the pre-mesh filter. This can be removed and rinsed as needed with warm soapy water and allowed to dry completely before putting it back on the machine (much like your vacuum’s sponge filter). Behind the pre-mesh filter is the Box filter, which does not need to be replaced until you’ve reached 5,000 hours (the hour-meter is the small digital display on the side of the unit) or one year of steady use.
Yes, we offer a one-year warranty on the concentrator. You can always upgrade to a three-year warranty.
