How does this compare to the "Aerobika" device?

The aerobica is an oscillating device. It’s purpose is to shake loose secretions. The breather is a complementary product as it strengthens your respiratory muscles giving you a strong cough reflex. It’s critical that you shake loose and expectorate those secretions. The Breather gives your muscles the strength to do so. It also contributes to a better distribution of inhaled medications.
