Quick Reference

The IRS defines medical expenses as costs for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for the purpose of affecting any structure or function of the body. Items that are merely beneficial to general health or are ordinarily used for personal, living, or family purposes are generally not considered qualified medical expenses. For an allergy air filter to be eligible, its primary purpose must be to alleviate or prevent a specific medical condition, as diagnosed by a medical professional.

When It Qualifies

  • Must be primarily for medical care to treat a diagnosed medical condition (e.g., severe asthma, chronic allergies).
  • Requires a Letter of Medical Necessity (LMN) from a doctor stating the medical necessity.

When It Doesn't

  • Used for general health improvement or comfort.
  • Used for general home air quality improvement without a specific medical diagnosis and recommendation.
