Looking for the best Nebulizer Unit for My Dad

Yesterday, I look for a nebulizer unit because the doctor instructed me to buy one for my fathers personal use. I visited a couple of medical stores to look for a better brand that is durable. There are a lot of models that are available in the market some are made from china and others are from Taiwan and United states. Most of the medical attendant recommends tha Omron brand because they said that this type of nebulizer unit is proven and tested. It is a portable type of unit white in color and very much handy. The price of nebulizers ranges from 2500 pesos the Taiwan brand, to 3300 pesos for the Omron brand and the high end brand cost 7800. I chose the Omron brand, it is so easy to operate for it has all the guides and instructions. I hope and pray that this could help a lot to my fathers medication.
