Dehumidifiers are typically not eligible for reimbursement with a Flexible Spending Account (FSA) or Health Savings Account (HSA). In rare cases, they may qualify with a Letter of Medical Necessity (LMN) if prescribed by a physician to treat a diagnosed medical condition.
Why Are Dehumidifiers Not FSA/HSA Eligible?
Dehumidifiers are appliances designed to reduce moisture in the air and improve indoor comfort. Because they are generally used to enhance living conditions or prevent household issues like mold, they are considered personal or household expenses rather than medical care.
According to IRS Publication 502, items that improve general health or provide a better living environment do not qualify as medical expenses. However, when a physician prescribes a dehumidifier as part of treatment for a specific medical condition — such as severe allergies, asthma, or other respiratory illnesses — the expense may be eligible with proper documentation.
What’s Not Covered?
Dehumidifiers purchased for general home comfort or mold prevention
Appliances bought without a doctor’s prescription and LMN
Household air-quality devices used for lifestyle or wellness purposes
LMN and Exceptions
In limited cases, a dehumidifier may qualify if a physician determines it is medically necessary to treat a diagnosed condition. Conditions that may justify an LMN include:
Chronic asthma aggravated by humidity
Severe allergies requiring air-quality control
Respiratory conditions where excess moisture worsens symptoms
To pursue reimbursement:
Obtain a diagnosis from your physician and request a Letter of Medical Necessity (LMN) specifying the condition and the medical need for a dehumidifier.
Submit the LMN to your FSA/HSA administrator before making the purchase.
If approved, purchase the device with your FSA/HSA card or pay out of pocket and request reimbursement.
Keep the LMN, receipts, and administrator approval for your records.
Because eligibility depends on medical necessity and administrator review, reimbursement is rare and should be confirmed in advance.
