Breathing easier at home doesn’t have to be complicated. A home oxygen concentrator like the VH-3 makes it simple. Instead of lugging around heavy tanks, it pulls oxygen from the air and gives you a steady, clean flow whenever you need it. Small, quiet, and easy to use, it works for both people and even small pets.

How the VH-3 Works

Using a home oxygen concentrator is easier than you think:

Step 1: Pull in air – The VH-3 takes in room air and filters out dust with a 10-layer system.
Step 2: Separate oxygen – A lithium sieve separates oxygen from nitrogen for up to 95% pure oxygen.
Step 3: Continuous flow – Set the flow from 1–7 L/min for you or your small pet.
Step 4: Comfort features – Auto-humidification keeps air from drying your nose, and the built-in nebulizer lets you get two therapies in one device.

It’s quiet, reliable, and makes breathing at home stress-free.
