How about Philips home ventilator?

Philips household ventilator is very easy to use. Philips is a big brand, so it is safe to use. Mine is Philips' and it's for my father. He is fat and often snores. We took him to the hospital for a polysomnography, and the results showed that it was apnea syndrome. The doctor suggested using a ventilator for treatment. Later, I bought my father a Philips noninvasive ventilator, which was also recommended by the doctor. The actual effect is also very good. Father's sleep quality is much better than before, and his voice is lower.
