You'll need a letter of medical necessity (LMN) from your doctor specifying your condition and that the air purifier is medically necessary. The LMN should ideally reference IRS Publication 502.

What to do next

Requires a letter of medical necessity from a doctor for a diagnosed respiratory condition (asthma, allergies, COPD, etc.).
