This is for educational purposes only—use at your own risk, start low, consult a functional doctor if you have any concerns. This is not medical advice.
Use distilled water or properly made CS (distilled water base), and a clean nebulizer. Always dilute (except straight CS); and test tolerance with tiny amounts first.

RECOMMENDED NEBULIZERS: 

Canada:

This one of the nebulizers I have. MedPro Sonair Ultrasonic Mesh nebulizer is the exact nebulizer Amandha Vollmer recommends. Self-cleaning (helps prevent clogs that mesh nebulizers are known for)

This is another great mesh nebulizer for Canada at less than half the price of the MedPro. I also got this nebulizer so I could test before recommending. I consider it to be the best choice on Amazon.

B0F1DFM7PR (Rechargeable, Self-Cleaning, Adjustable Mist, Digital Display)

• Pros: USB rechargeable (no batteries!), 3 mist speeds (customize for comfort/DMSO), timer/digital screen, quiet (<25 dB). Reviews (4.2/5 from ~10–20) praise ease, portability, self-cleaning works well for daily CS/saline. Good for your 20% DMSO plans (adjust low speed to start).
• Cons: Slightly pricier (~$70–$80), some early reviews mention battery life ~20–30 sessions per charge.
• Overall: Premium feel for the price — my top pick of the mesh nebulizers available on Amazon.
