GVS Oxygen 5L Oxy-Pure Ultra Silence Oxygen Concentrator, Grey

Very good product with in the price range, delivery was very quick, got the machine on the same day of purchase...before purchasing I had contacted with GVS persons, they were very responsible explained clearly about the product, also instructed how to use it. Machine is running good till date with low noise from the day of purchase. And I appreciate the customer service people , as they are enquiring about their product regularly like how it's running, any issues I'm facing...never heard a company refering back to the customer after purchasing the product , like GVS enterprises did. Thanks to GVS. and I hope this type of services will be continued to the customers.

I brought it for my father, in 2025,and it has been working excellent without any issues till date.

Good product. works well. Low noise.

A really useful medical device and works so well. Easy to use.

Excellent product. Hsve been using it daily for the last 10 months. Well worth the money.

My father did not receive oxygen from this machine and because of this my father passed away today doctor told me to despite proper installation and usage as per the instructions the machine failed to supply oxygen. This is an extremely serious matter involving product failure at a critical time. I have another machine last 4 years but that machine work properly i also request a refund of the product.

Easy to install. Installed with 1kv stablizer. Less noise. Easy to use like ON/OFF.

Working good.Nice product
