Best Breathing Trainers
for COPD of 2026

A 2021 meta-analysis of 32 randomized controlled trials found that inspiratory muscle training (IMT) significantly improves exercise capacity, dyspnea scores, and quality of life in COPD patients. On the strength of that evidence, the ATS/ERS recommends IMT as an adjunct therapy for patients with inspiratory muscle weakness.

#1

Airofit PRO Breathing Trainer

The Airofit PRO is the most advanced consumer breathing trainer available. It measures RMV (respiratory minute volume), inhalation flow rate, exhalation flow rate, and breath-hold capacity in real time, so you can track how your respiratory function changes over time. The companion app runs structured COPD-specific training programs developed with pulmonologists, and it adjusts resistance as you progress. The data is clinical enough to hand to your respiratory therapist or pulmonologist.

What we loved

  • Real-time respiratory measurements
  • COPD-specific guided programs
  • Tracks FVC, FEV1 proxies over time
  • Clinician-shareable data
  • Adjustable resistance (0–190 cmH₂O)

What to know

  • Premium price ($199)
  • Requires subscription for full app

Expand-A-Lung Breathing Exerciser

The Expand-A-Lung trains both inhale and exhale resistance in a simple, no-frills design. It was the most portable and affordable genuine IMT device we tested, with no batteries, no charging, and no setup. A good fit for anyone who wants a breathing tool they can carry anywhere and use without drawing attention.

What we loved

  • Works both inhale and exhale
  • Ultra-portable
  • No charging/batteries
  • Budget-friendly

What to know

  • Fixed resistance (not adjustable)
  • No progress tracking

#3

Threshold IMT (Philips Respironics)

The Threshold IMT is the device used in most clinical research on inspiratory muscle training in COPD. Its spring-loaded, threshold resistance mechanism delivers consistent, measurable training loads no matter the breathing rate, which is what separates genuine IMT from simple resistance breathing. Respiratory therapists recommend it worldwide, and the ATS/ERS COPD management guidelines reference it directly.

What we loved

  • Used in clinical research trials
  • True threshold resistance (not flow-dependent)
  • Physiotherapist recommended
  • Durable, proven design

What to know

  • No digital measurements
  • No app connectivity
  • Manual resistance adjustment

POWERbreathe Medic

The POWERbreathe Medic is built for patients with compromised respiratory function, including GOLD 3–4 COPD. It starts at resistance levels low enough that more powerful devices cannot match them, which lets people who find standard IMT devices too hard at first build up gradually and safely. It is NHS-approved in the UK and recommended by pulmonary rehabilitation specialists for severe cases.

What we loved

  • Ultra-low starting resistance
  • Designed for severe COPD
  • NHS approved
  • Safe for very weak inspiratory muscles

What to know

  • Lower max resistance ceiling
  • No digital tracking

Acapella Vibratory PEP Device

Clinically Validated

The Acapella stands apart from the rest of this list: it pairs positive expiratory pressure (PEP) with high-frequency oscillation to loosen and clear mucus from the airways. It isn't really a strength trainer, but for COPD patients with chronic bronchitis who struggle to clear mucus, it can cut coughing episodes and clear the airways better than any other home device. It comes in two resistance levels.

What we loved

  • Unique oscillatory PEP mechanism
  • Clinically proven mucus clearance
  • Works at any orientation
  • Recommended by respiratory therapists

What to know

  • Not a strength trainer per se
  • Requires cleaning after each use

Questions, answered.

How did HealthRankings choose these breathing trainers for copd & respiratory strength?

Our editorial team independently researches, tests, and evaluates products using a weighted scoring methodology. We assess accuracy, ease of use, value for money, and category-specific criteria relevant to each condition. Every product is scored on a 10-point scale, and only the top 5 make our final list.

We buy every product at retail — no manufacturer samples — and our medical reviewers have no financial relationship with any brand we cover.

How often are these rankings updated?

We update our rankings at least once per quarter, and immediately when a significant new product launches or when we discover issues with a previously ranked product. Our current rankings were last verified in April 2026.

If a product is discontinued, recalled, or its price changes significantly, we update the listing within one business day.

Is the #1 pick always the best choice for everyone?

Not necessarily. Our #1 pick (Airofit PRO Breathing Trainer) scored highest overall, but the best product for you depends on your specific needs, budget, and preferences. For example, if budget is your primary concern, a lower-ranked product with a better value score might be the better choice.

We recommend reading through all 5 reviews and paying attention to the "What to know" sections to find the best fit for your situation.

Are these products covered by insurance or HSA/FSA?

Many health monitoring devices and home testing kits qualify for HSA (Health Savings Account) and FSA (Flexible Spending Account) reimbursement. However, coverage varies by plan and product category. We recommend checking with your insurance provider or benefits administrator before purchasing.

Some products in our list may also be partially covered by Medicare or Medicaid depending on your diagnosis and prescription.

Can I return a product if it doesn't work for me?

Return policies vary by retailer and manufacturer. Most Amazon purchases can be returned within 30 days. Many manufacturers offer satisfaction guarantees ranging from 30 days to 1 year. Check the specific return policy before purchasing.

If a product is defective, most manufacturers will replace it under warranty regardless of the retailer's return window.

Should I consult my doctor before using these products?

Yes — we always recommend discussing new health monitoring devices or tests with your healthcare provider, especially if you have a diagnosed condition. Your doctor can help you understand your results, set appropriate monitoring schedules, and integrate home monitoring data into your overall treatment plan.

These products are designed to supplement — not replace — professional medical care.
