What to Consider When Shopping for a Home Oxygen Concentrator?

Choosing the right device from an oxygen concentrator store can be overwhelming, especially when you need a dependable stationary oxygen machine for everyday home use.

From oxygen purity and flow rate to noise level and smart features, several factors come into play. In this guide, we’ll walk you through what to consider—and spotlight five trusted models from VARON designed to meet different needs.

1. Oxygen Purity and Flow Rate

The most critical aspect of any stationary oxygen machine is the level of oxygen concentration it delivers. A healthcare-grade concentrator like the VARON Serene 5 provides 93±3% oxygen purity at all flow settings, adjustable between 0.5 to 5L/min.

This ensures consistent oxygen delivery regardless of setting—a vital requirement for users with chronic respiratory conditions.

Similarly, the VARON 105W Pro delivers 93±3% concentration at 1–2L/min, with an extended flow range up to 8L/min, offering flexibility for users needing higher outputs.

2. Continuous Flow Performance

When shopping at a professional oxygen concentrator store, make sure the model offers continuous flow if you need steady oxygen delivery around the clock.

All VARON models featured here—Serene 5, 105W Pro, VH-2, VH-1, and VH-3—provide continuous flow, ideal for both daytime and nighttime use.
