What to do if you buy a waterborne respirator?

Generally can only self-admit bad luck, back is not returned. Because since the sale of water goods to you, that they simply did not consider what conscience and after-sales, your machine late failure simply can not find a place to repair, usually normal testing and calibration of the liquid more do not want to.

The way to avoid buying water goods is to go to a regular store to consult, online now even the official website can be imitation of the real hard to distinguish, a lot of people fooled.

I'm a product engineer at Breathecon, and every once in a while someone will come to the service center to let me test the machine to see if it's real or fake, in addition to parallel imports, there are also people with refurbished machines and even cottage machines to do a "counter inspection", most of the results are another person's regrets.

In a word, the ventilator is a professional medical device that requires special commissioning and tracking of therapeutic effects, and in the later stages of use, it also requires maintenance and testing and calibration, so it's best not to choose to buy it on the Internet.
