Managing a respiratory condition at home means making smart decisions about equipment that directly affects your breathing — and your life. Whether you're newly diagnosed with COPD, recovering from surgery, or supporting a family member with sleep apnea, understanding your options for home oxygen equipment respiratory supplies is the first step toward better care.
Understanding the Main Types of Equipment
Home respiratory equipment covers a wide range of devices, each designed for specific conditions and usage patterns.
Oxygen concentrators are the most common choice for long-term home oxygen therapy. They pull oxygen from room air and deliver it at concentrations of 87–99%, without the need for refillable tanks. Stationary models typically deliver 1–10 litres per minute (LPM), while portable units offer 1–3 LPM for users who stay active.
Oxygen cylinders remain useful as backup systems or for patients who only need supplemental oxygen occasionally. They come in sizes ranging from small E-cylinders (lasting roughly 4–5 hours at 2 LPM) to larger H-cylinders for extended home use.
CPAP and BiPAP machines address sleep-disordered breathing. CPAP delivers a single continuous pressure, while BiPAP offers two pressure levels — making it better suited for conditions like obesity hypoventilation syndrome or central sleep apnea.
Nebulisers convert liquid medication into a fine mist for direct delivery to the lungs. These are commonly used for asthma, bronchiectasis, and COPD flare-ups.
Buying vs. Hiring: What Makes Sense?
Choosing between purchase and rental depends on how long you'll need the equipment and how your needs might change.
- Hire/rental suits short-term needs (post-surgery recovery, trial periods) and usually includes maintenance and servicing. Typical oxygen concentrator rental runs between £50–£120 per month in the UK, or $80–$200/month in the US.
- Buying outright is more cost-effective for long-term users. A quality stationary concentrator ranges from £400–£1,500 depending on brand and flow rate; portable units typically cost £700–£2,500.
- Insurance and NHS coverage may fund equipment for qualifying conditions — always check eligibility before paying privately.
- Refurbished equipment can cut costs by 30–50% but always confirm it comes with a warranty and has been properly serviced.
Key Features to Compare Before You Commit
Not all devices are created equal. When evaluating options, focus on:
- Flow rate range — does it cover your prescribed LPM?
- Noise level — concentrators range from 37 to 60 decibels; quieter matters if you use it overnight
- Weight and portability — portable concentrators range from 1.5 kg to 4.5 kg
- Battery life — for portable units, look for at least 4–6 hours with a backup charging option
- Alarm systems — low oxygen purity alerts and power-failure warnings are essential safety features
- Filter maintenance schedule — some units need weekly cleaning, others monthly
- Warranty length — reputable manufacturers offer 3–5 years on the compressor
Prescription and Safety Requirements
In most countries, home oxygen therapy requires a prescription from a licensed physician following a blood oxygen assessment (typically SpO₂ below 88% or PaO₂ below 55 mmHg qualifies). Never self-prescribe oxygen flow rates — incorrect settings can actually suppress breathing drive in certain COPD patients.
For CPAP and BiPAP, a sleep study (polysomnography) is standard before a prescription is issued. Your prescribed pressure settings should be programmed by a qualified respiratory therapist or supplier, not adjusted at home without guidance.
Keep equipment away from open flames and ensure your home has adequate ventilation — oxygen accelerates combustion. Store cylinders upright and secured to prevent tipping.
Finding a Trusted Supplier
The quality of your supplier matters as much as the equipment itself. Look for providers who offer:
- In-home setup and patient education
- Ongoing clinical support or a nurse helpline
- Clear servicing and replacement parts policies
- Accreditation from relevant health authorities (CQC in the UK, ACHC or The Joint Commission in the US)
Mercoly lets you compare and find trusted oxygen and respiratory equipment providers in one place, saving you hours of independent research when you need answers quickly.
Questions to Ask Before Signing Anything
Before committing to a rental agreement or purchase, get clear answers on:
- What happens if the equipment fails overnight?
- Is 24/7 technical support included?
- Are consumables (masks, tubing, filters) included or extra?
- What is the returns or upgrade policy if your needs change?
Getting these answers in writing protects you and ensures you're not caught off guard by hidden costs.
