Air purifiers are eligible for reimbursement with a Medical Necessity Letter (LMN) from your doctor or healthcare provider when using a Flexible Spending Account (FSA), Health Savings Account (HSA), or Health Reimbursement Arrangement (HRA). This means that if air quality has an impact on your medical health, you can now get the relief you need. When considering an air purifier, it is important to take into account the size of the room. To effectively clean the air in a room, you will need to change the air in the room several times per hour.
The recommended number of air exchanges is five per hour, while two exchanges can be considered a minimum requirement. The latest air purification technology is also capable of eliminating a wide range of bacteria, viruses, and DNA-damaging particles (WebMD). Keep in mind that filters can be costly to replace and a removable filter that can be cleaned may be more practical. Other products such as steam inhalers, air purifiers, or water filters may also be eligible for reimbursement but would require a doctor's note of medical necessity.
