      facing very worst experience with dispatch team. They are not understanding the urgency and not speaking irresponsibly. I think it Is better to purchase direct..

      This product is not bad. But remember this can’t be used 24X7 even if they claim so. It needs to be stopped and compressor needs to be given rest for at least half an hour after 10 hours of operation. Also be very careful about return policy. They will not accept return even if you are not satisfied with the product and make a claim within 10 days of receipt.

      • Hi Sir,

        This is a health care equipment. This is like any other machine. It has a compressor inside and continually working. It can be used 24X7 we suggest give some rest for the machine to increase the efficiency of the machine. As we mentioned in the return policy the equipment can be accepted in original manufacturing condition and shall be in resalable. We follow 10 days policy as per the website. If you use it for 10 days it will not be in resalable position. So Kindly cooperate.

      Hi Sir,

         Good question. The machine should not be taken to the rest room. For this purpose we have a solution , we have 7.6 meter oxygen cannuala at WWW.medicalbulkbuy.com and you can place order separately for that to use the machine in rest room or Bath room. Using this you can keep the machine away from water short circuit and (Keep out side the Room) and use the flow of oxygen. Contact our customer care by chat for 7.6 meter oxygen cannula in case of any difficulty.

      Hi sir ,

         This can not be used in car or Ambulance. Only portable Oxygen concentrators can be used in car.

      Hi Sir,

         It does not work on battery. It works on AC current only. For battery type we have Portable Oxygen Concentartor at www.medicalbulkbuy.com

      The cost of filters is around 450/- Rs. We are providing additional filter with the machine. There is one external filter(square type ) and internal filter. Dust is collected at external filter and then passes through the internal filter. Machine attendant has to maintain the filters clean so that there will be less load on the machine. This leads to longer life of the machine. Both the filters are washable with tap water and air dried and to be kept back. One has to take care there will be no moisture in the filters.

      Yes sir it has wheel at below the machine and one can roll the machine from room to other. We suggest just hold and pull the machine as it is easy. pulling by power cord leads to loose contact and pulling by oxygen cannula leads to damage to humidifier bottle.

      Hi Sir,

       It does not come with Oxygen Analyser. We test the concentartors Prior to dispatch to keep it in our records.

      A General recommendations to GVS Oxygen Concentrator as follows... 1. Use 1 KV Stabilizer  along with the machine. 2. Always leave space about 1 feet from the wall. 3. Clean filters when once in a while. 4. Do not smoke near the machine 5. Do not pull the machine with oxygen cannula that may damage the humidifier bottle. 6. Give gap for every 9 hrs of operation( let the machine cool down at least 30 mins.)

      A You need not change any parts. It requires simple cleaning of sponge filter in water and dry it and need to put back. It is on backside of machine and follow the manual instructions. We provide additional filter with the machine. You can use continuously and along with stabilizer. We give replacement warranty for any manufacturing defects during warranty period
