What Is a Portable Oxygen Can and How Can It Help You?

 

Breathing feels effortless most of the time — until it doesn't. Whether you're recovering after intense exercise, travelling to high altitude, or simply feeling short of breath during a demanding day, the Cured Pharmacy portable oxygen can offers a convenient, ready-to-use source of supplemental oxygen. Each 15-litre canister comes complete with a mask and tube, so you have everything you need straight out of the box. At just £21.49, it's an accessible option for anyone wanting a short-term oxygen boost without a prescription. If you're also managing other health concerns alongside breathlessness, our First Aid collection includes a range of products to support your wellbeing.

Supplemental oxygen has been used for decades in both clinical and non-clinical settings. The NHS recognises that low blood oxygen — known as hypoxaemia — can cause fatigue, confusion, and shortness of breath. While this canister is not a medical device for treating diagnosed respiratory conditions, it is designed for short-term, situational use where a temporary oxygen boost may be beneficial.

 

How Does the 15L Oxygen Can Work?

 

The canister contains oxygen at approximately 99% purity — significantly higher than the roughly 21% oxygen found in normal air. When you press the valve, oxygen is released through the tube and delivered via the mask directly to your airways. Here's how the process works:

  • You press the canister valve to release a controlled flow of oxygen.
  • Oxygen travels through the tube and into the mask, which sits over your nose and mouth.
  • You inhale normally, drawing in the concentrated oxygen with each breath.
  • The higher oxygen concentration in each breath temporarily raises the oxygen saturation in your blood.
  • This can help reduce feelings of breathlessness, fatigue, or light-headedness in appropriate situations.

It's worth noting that this is a short-term, situational product. It is not designed to replace continuous or long-term oxygen therapy, which must always be prescribed and supervised by a medical professional.

 

Who Is This Oxygen Can Suitable For?

 

This product is intended for adults seeking a temporary, supplemental oxygen source in non-clinical situations. It may be particularly useful for:

  • Travellers visiting high-altitude destinations where the air is thinner.
  • Athletes or fitness enthusiasts looking for a quick recovery aid after strenuous exercise.
  • People experiencing temporary breathlessness due to fatigue or environmental factors.
  • Individuals who want a portable oxygen source for general wellbeing or peace of mind during travel.

This product is not suitable for people with diagnosed respiratory conditions such as COPD, asthma, or heart failure without prior medical advice. If you have any underlying health condition affecting your breathing, please speak to your GP before use.

 

How Does This 15L Can Compare to Other Oxygen Canisters?

Volume 15 litres 2 litres
Includes mask and tube Yes Often not included
Approximate uses 50–60 bursts 6–10 bursts
Price £21.49 Typically £5–£10

 

How Should You Store and Handle This Oxygen Can?

 

Proper storage is essential for both safety and product longevity. The portable oxygen can should be kept upright in a cool, dry location, away from direct sunlight, radiators, or any open flame. Oxygen accelerates combustion, so it must never be stored near flammable materials or used while smoking. Keep the canister out of reach of children at all times.

Once opened, use the canister within the period indicated on the packaging. Do not puncture, incinerate, or attempt to refill the canister. If you're travelling with it, check airline regulations before packing it in your luggage. For those managing multiple health needs while travelling, our Travel collection has a range of useful products to keep you prepared on the go.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of 15L Oxygen Can with Mask and Tube

 

What Is the 15L Oxygen Can and What Is It Used For?

 

The Cured Pharmacy 15L Oxygen Can with Mask and Tube is a pressurised canister containing high-concentration oxygen (approximately 99% purity) for short-term inhalation use. It is supplied as an over-the-counter product and is intended for situational, non-clinical supplemental oxygen needs. Common uses include temporary relief of breathlessness at altitude, post-exercise recovery, and general fatigue associated with low-oxygen environments.

This product is not a medical oxygen device and is not intended to treat, diagnose, or manage any diagnosed medical condition. If you experience persistent or unexplained breathlessness, you should seek medical advice promptly. The NHS advises that sudden or severe shortness of breath always warrants urgent assessment.

 

What Do You Need to Know Before Using This Oxygen Can?

 

Before using this product, read the following carefully. There are situations where use may not be appropriate or where you should seek medical advice first.

Do not use this product if you:

  • Have been diagnosed with COPD, emphysema, or any condition where controlled oxygen levels are medically managed.
  • Have a known hypersensitivity to high-concentration oxygen therapy.
  • Are using it as a substitute for prescribed medical oxygen therapy.
  • Are near open flames, lit cigarettes, or flammable materials — oxygen supports combustion.

Use with caution if you:

  • Have any chronic respiratory or cardiovascular condition.
  • Are pregnant or breastfeeding — consult your GP before use.
  • Are using this product for a child — this canister is intended for adult use only.

Known interactions:

  • No significant drug interactions are known for short-term inhalation of supplemental oxygen in healthy adults.
  • In people with certain respiratory conditions, supplemental oxygen can suppress the hypoxic drive to breathe — always seek medical advice if you have a lung condition.

 

How Should You Use the 15L Oxygen Can?

 

Using this canister correctly ensures you get the most benefit while staying safe. Follow these steps carefully each time you use it.

  1. Remove the canister from its packaging and inspect it for any visible damage before use.
  2. Attach the tube securely to the valve nozzle on the top of the canister.
  3. Connect the other end of the tube to the mask.
  4. Place the mask over your nose and mouth, ensuring a comfortable, snug fit.
  5. Press the valve to release oxygen and breathe in slowly and normally through the mask.
  6. Use for the recommended duration — typically a few breaths to a minute at a time — then release the valve.
  7. Remove the mask and breathe normally. Repeat as needed, following the guidance below.
Indication Age Group Dose Frequency
Altitude-related breathlessness Adults 3–5 breaths per session As needed, up to several times daily
Post-exercise recovery Adults 3–5 breaths per session After exercise as required
General fatigue / breathlessness Adults 3–5 breaths per session As needed — do not use continuously

If you're also managing pain or discomfort alongside breathlessness, you may find our Pain Relief collection helpful for complementary support.

 

What Are the Possible Side Effects of This Oxygen Can?

 

Side effects from short-term use of supplemental oxygen in healthy adults are uncommon. However, as with any inhalation product, some people may notice the following.

Common side effects:

  • Dryness of the mouth, throat, or nasal passages after repeated use.
  • Mild dizziness if used excessively or too rapidly.
  • Slight headache following prolonged inhalation sessions.

Less common side effects:

  • Nausea in sensitive individuals, particularly if used at high frequency.
  • Feeling of chest tightness — stop use immediately and seek medical advice if this occurs.
  • In people with COPD or hypercapnic respiratory failure, supplemental oxygen can dangerously suppress the drive to breathe — this is a serious risk and such individuals must not use this product without medical supervision.

Stop using the canister and contact your GP or call 111 if you experience worsening breathlessness, chest pain, or any unusual symptoms after use.

 

How Should You Store the 15L Oxygen Can?

Frequently Asked Questions

Where can I buy a portable oxygen can online in the UK?

You can buy the Cured Pharmacy 15L portable oxygen can with mask and tube directly from Cured Pharmacy online for £21.49. It is available without a prescription as an over-the-counter product. Simply add it to your basket and it will be dispatched to your door.

How does a portable oxygen can work in the body?

The canister delivers oxygen at approximately 99% purity — far higher than the 21% found in normal air. When you inhale through the mask, this concentrated oxygen enters your lungs and temporarily raises the oxygen saturation in your bloodstream. The result is a short-term reduction in feelings of breathlessness or fatigue.

How do I use the 15L oxygen can with mask and tube step by step?

Attach the tube to the canister valve, then connect the tube to the mask. Place the mask over your nose and mouth, press the valve to release oxygen, and breathe in slowly and normally. Use for a few breaths per session, then release the valve and breathe normally.

How many uses does a 15L oxygen can provide?

A 15-litre canister typically provides approximately 50–60 one-second bursts of oxygen, though this varies depending on how deeply and how long you inhale per session. Shorter, controlled inhalations will extend the life of the canister. It offers significantly more uses than smaller 2L canisters.

Is a portable oxygen can safe to use at home?

Yes, when used as directed, a portable oxygen can is generally safe for short-term supplemental use in healthy adults. You must keep it away from open flames, heat sources, and flammable materials, as oxygen accelerates combustion. It is not a substitute for medically prescribed oxygen therapy.

Who should not use a portable oxygen can?

People with COPD, emphysema, or other conditions where oxygen levels are medically managed should not use this product without speaking to their GP first. In these individuals, supplemental oxygen can suppress the body's drive to breathe, which is potentially dangerous. Children should also not use this product.

Can I use an oxygen can for altitude sickness?

Portable oxygen cans are widely used by travellers to provide temporary relief from breathlessness and fatigue associated with high altitude. However, they are not a treatment for acute mountain sickness, and the NHS advises that descent remains the most effective intervention. Use the canister for symptomatic relief only, and seek medical help if symptoms are severe.

What is the best time to use a portable oxygen can?

Use the canister whenever you experience temporary breathlessness or fatigue in appropriate situations — such as immediately after intense exercise, upon arriving at altitude, or during periods of exertion in low-oxygen environments. There is no fixed time of day; use it as and when needed. Avoid using it continuously or as a daily habit without medical guidance.

What are the side effects of using an oxygen can?

Side effects from short-term use are uncommon in healthy adults but can include dryness of the mouth or throat, mild dizziness, and occasional headache if used excessively. If you experience chest tightness or worsening breathlessness, stop use immediately and contact your GP or call 111. Overuse in people with certain lung conditions can be dangerous.

How do I manage side effects from using an oxygen can?

If you notice dryness in your mouth or throat, drinking water before and after use can help. Limit each session to a few breaths rather than prolonged inhalation to reduce the risk of dizziness or headache. If any side effect persists or concerns you, stop use and speak to a pharmacist or GP.

Who is eligible to buy a portable oxygen can in the UK?

This product is available over the counter to adults in the UK without a prescription. It is intended for healthy adults seeking short-term supplemental oxygen for situational use. People with diagnosed respiratory or cardiovascular conditions should consult their GP before purchasing. It is not intended for use in children.

What happens if I use too much oxygen from the can?

Using too much supplemental oxygen in a short period can cause dizziness, headache, or nausea in some people. In individuals with certain lung conditions, excessive oxygen can suppress the respiratory drive, which is a serious medical concern. Always follow the usage guidance and do not use the canister continuously.

What are the alternatives to a portable oxygen can?

Alternatives include smaller 2L or 8L portable oxygen canisters for lighter use, or medically prescribed home oxygen concentrators for clinical respiratory conditions. For diagnosed conditions, your GP can refer you for NHS home oxygen therapy. You might also explore our Electrical Health and Diagnostic range for pulse oximeters to monitor your oxygen levels at home.

How long can you use a portable oxygen can for?

This product is designed for short-term, situational use only — not for ongoing daily therapy. Each session should last only a few breaths, and the canister should be used over days or weeks depending on your needs. If you find you are relying on supplemental oxygen regularly, speak to your GP, as this may indicate an underlying health issue that needs assessment.

What does the latest research say about portable oxygen cans?

Research into portable supplemental oxygen is largely focused on clinical settings and altitude medicine. Studies suggest that short-term oxygen supplementation can temporarily relieve breathlessness and improve exercise tolerance in healthy individuals at altitude. However, evidence for routine use in everyday fatigue management in healthy adults at sea level remains limited, and it should not replace medical assessment for persistent symptoms. For general wellbeing support, our Vitamins and Supplements collection may also be of interest.

How Should You Use the 15L Oxygen Can with Mask and Tube?

Using this canister correctly is straightforward, but it's important to follow each step to ensure you get the benefit safely. Before your first use, inspect the canister for any visible damage and check the expiry date on the label.

Never share the mask with another person without thorough cleaning. Always replace the cap on the valve when not in use to prevent accidental discharge.

What Is the Correct Dose of the 15L Oxygen Can?

There is no single fixed dose for supplemental oxygen canisters, as usage depends on the situation and individual need. As a general guide, most people benefit from 3–5 slow, controlled breaths per session. Do not use the canister continuously or for extended periods without medical advice.

When Is the Best Time to Use the 15L Oxygen Can?

Use the canister whenever you experience temporary breathlessness, fatigue, or light-headedness in a situation where supplemental oxygen may help — such as immediately after strenuous exercise, upon arriving at a high-altitude location, or during periods of exertion in low-oxygen environments. There is no fixed time of day; the canister is designed for on-demand, situational use. Avoid using it as a preventative measure before symptoms arise, and do not use it as a substitute for rest or medical treatment.

How Long Can You Use the 15L Oxygen Can For?

This product is intended for short-term, situational use only. A single 15-litre canister provides approximately 50–60 one-second bursts, which should last across multiple sessions over days or weeks depending on your usage pattern. It is not designed for continuous or daily long-term use. If you find yourself relying on supplemental oxygen regularly, this may indicate an underlying health issue — speak to your GP for a proper assessment. Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of the 15L Oxygen Can?

For most healthy adults using this canister as directed, side effects are uncommon and mild. The most frequently reported effects relate to the drying nature of concentrated oxygen on the airways.

  • Dryness of the mouth, throat, or nasal passages after repeated use.
  • Mild dizziness, particularly if you inhale too quickly or for too long.
  • Slight headache following prolonged or excessive inhalation sessions.

These effects typically resolve quickly once you stop using the canister and breathe normally. Drinking water before and after use can help reduce dryness.

What Are the Less Common Side Effects of the 15L Oxygen Can?

Less commonly, some individuals may experience the following after using supplemental oxygen:

  • Nausea, particularly if the canister is used at high frequency in a short period.
  • A feeling of chest tightness or discomfort — stop use immediately if this occurs.
  • Tingling in the fingers or lips, which can occur with rapid or excessive inhalation.

These effects are more likely if the product is used incorrectly or more frequently than recommended. Always follow the usage guidance provided.

What Are the Serious Side Effects of the 15L Oxygen Can?

Serious side effects from short-term supplemental oxygen use in healthy adults are rare. However, in people with COPD or hypercapnic respiratory failure, supplemental oxygen can dangerously suppress the hypoxic drive to breathe — this is a well-recognised clinical risk. If you have any diagnosed lung condition, do not use this product without explicit medical advice. Additionally, oxygen accelerates combustion, so using the canister near open flames or while smoking poses a serious fire hazard. Stop use immediately and seek emergency help if you experience severe chest pain, worsening breathlessness, or loss of consciousness.

What Should You Do If You Experience Side Effects?

If you notice mild side effects such as dryness or dizziness, stop using the canister, rest, and drink water. These should resolve within a few minutes. If you experience chest tightness, severe dizziness, or any symptom that concerns you, stop use immediately and contact your GP or call NHS 111. In an emergency, call 999. Do not continue using the canister if you are unsure whether it is safe to do so.

Can the 15L Oxygen Can Interact With Other Medicines?

No significant drug interactions are known for short-term inhalation of supplemental oxygen in healthy adults. However, if you are taking medicines for a respiratory or cardiovascular condition — such as bronchodilators, corticosteroids, or diuretics — you should speak to your pharmacist or GP before using this product. The interaction risk is not pharmacological but physiological: supplemental oxygen can alter respiratory physiology in people whose breathing is already medically managed. If in doubt, always seek professional advice before use. If you are concerned about any side effects, contact your pharmacist or GP immediately.
