Air pollution has become a bigger worry for many people in recent years, especially those with breathing problems or allergies. People often use air filters to fight the bad effects of polluted air. These devices remove harmful particles and improve the quality of the air inside. But a recurring question is ‘Does Medicare cover air purifiers?’ Dive into this comprehensive guide to understand the extent of Medicare’s coverage for air purifiers and make informed decisions about improving your indoor air quality.

Understanding Medicare

Medicare is a federal health insurance program in the United States that provides coverage for eligible individuals 65 years or older and certain younger individuals with disabilities. It is divided into different parts, each covering specific services and supplies.

Medicare Parts A, B, C, and D

Part A, Part B, Part C, and Part D are the four primary components of Medicare. Part A covers inpatient and outpatient hospital care, skilled nursing facility care, hospice care, and certain home health care.

Visits to the doctor, outpatient treatment, preventative services, and durable medical equipment (DME) are all covered under Part B. Medicare Advantage or Part C, combines the advantages of Medicare Parts A and B and frequently includes coverage for prescription drugs under Medicare Part D. Prescription drug coverage is offered through Part D.

Coverage Criteria for Air Purifiers

To determine if Medicare covers air purifiers, several factors come into play.

Medical Necessity: Medicare generally covers air purifiers when they are considered medically necessary for individuals with respiratory conditions, allergies, or asthma. These conditions must be documented by a healthcare provider and meet specific criteria set by Medicare.

Prescription Requirement: A prescription from a healthcare provider is typically required to obtain coverage for an air purifier. The prescription should outline the medical necessity and specify the type and features of the air purifier required.

Air purifiers are considered durable medical equipment (DME) and are therefore covered by Medicare Part B. When DME, such as air purifiers, are declared medically necessary, they may be covered by Medicare Part B. However, coverage is subject to certain limitations and requirements.

Coverage Limitations: There are some caveats to Medicare’s potential coverage of air purifiers. Cost sharing, such as deductibles and coinsurance, may apply. Additionally, some air purifiers may require prior authorization before coverage is approved.

Non-Coverage of Air Purifiers

It’s important to note that Medicare does not cover standalone air purifiers that are not deemed medically necessary. Air purifiers used for non-medical purposes, cosmetic purposes, or personal preference generally do not qualify for coverage.

Alternative Coverage Options

If Medicare does not provide sufficient coverage for air purifiers, alternative options may be available.

Medicare Advantage (Part C): Private insurance firms granted Medicare permission to sell Medicare Advantage plans serve as providers. These plans often offer benefits in addition to those provided by Original Medicare. Some Medicare Advantage plans may cover air purifiers as an extra perk.

Medicaid: Medicaid is a state and federally-funded health insurance program for low-income families and individuals. Medicaid coverage varies by state, but in some cases, it may cover air purifiers for eligible individuals with specific medical conditions.

Other Insurance Options: Private health insurance plans and Medicare supplement plans (Medigap) may offer additional coverage options for air purifiers. Private insurance companies sell these plans and can help fill the gaps in Medicare coverage.

Steps to Obtain Coverage

To obtain coverage for an air purifier under Medicare, several steps need to be followed:

  1. Consultation with Healthcare Provider: Discuss your health condition with your healthcare provider and determine if an air purifier is medically necessary.
  2. Documentation and Prescription: Obtain a written prescription from your healthcare provider that clearly outlines the medical necessity and specifications of the air purifier required.
  3. Contacting Medicare and Insurance Providers: Reach out to Medicare and your insurance provider to understand their coverage policies and requirements.
  4. Coverage Verification and Approval: In order to confirm coverage and gain approval from Medicare and other insurance carriers, certain documents and procedures must be followed.
  5. Supplier Selection and Purchase: Choose a supplier that meets the Medicare supplier standards and purchase the air purifier as per the prescribed specifications.


While air purifiers have proven beneficial in improving indoor air quality, Medicare’s coverage for these devices is limited. Generally, Medicare Part B may cover air purifiers if they are deemed medically necessary for individuals with respiratory conditions or allergies. However, obtaining coverage involves the following:

  • Meeting specific criteria, including obtaining a prescription.
  • Satisfying medical necessity requirements.
  • Adhering to DME supplier standards.

The best way to find out if your health insurance covers an air purifier is to discuss the matter with your physician.

Additionally, alternative options like Medicare Advantage plans or Medicaid may offer more comprehensive coverage for air purifiers. Exploring other insurance options, such as private health insurance or Medicare supplement plans, is also worth considering.

Remember, each case is unique, and coverage depends on several factors. Stay informed, follow the appropriate steps, and work closely with your healthcare provider and insurance providers to maximize your chances of obtaining coverage for an air purifier if it is deemed necessary for your health and well-being.
