If you or someone you love needs supplemental oxygen, you’ve probably compared an oxygen tank with a portable oxygen concentrator. I completely understand—this decision can feel overwhelming at first. In this blog, I’ll walk you through the differences in a clear and friendly way, so you can confidently choose the option that matches your lifestyle and oxygen needs. What Is an Oxygen Tank? An oxygen tank stores either compressed oxygen gas or liquid oxygen inside a metal cylinder. When the valve opens, oxygen flows out and goes directly to your cannula or mask. It’s simple, reliable, and widely used—but different types vary a LOT in weight, price, and how long they last. Let’s break them down clearly. Types of Oxygen Tanks (With Weight, Price & Usage Time) 1. Compressed Oxygen Cylinders (Gas Tanks) This is the most common type, stored at high pressure inside steel or aluminum cylinders. Below are typical sizes you’ll see in home and medical use: Cylinder Size Approx. Weight Approx. Capacity Typical Duration* Approx. Price M9 (C Cylinder) ~3–4 lbs ~255 L ~1–2 hrs at 2 L/min $60–$120 D Cylinder ~5–6 lbs ~400–500 L ~2–3 hrs at 2 L/min $100–$150 E Cylinder ~8–9 lbs ~680 L ~3–5 hrs at 2 L/min $100–$200 Large Steel Cylinder (125–250 cu ft) 30–50 lbs thousands of liters many hours/days depending on flow $300–$500+ *Times vary based on your oxygen flow rate. ➡ Who uses these?People who spend most of their time at home, or who need backup oxygen in case of power outages. 2. Liquid Oxygen Tanks (LOX Systems) Liquid oxygen is stored at extremely low temperatures, so the same tank holds MUCH more oxygen than gas cylinders. Portable LOX Units: Weight: ~4 lbs Usage time: ~8–10 hours at setting 2 Large Home LOX Reservoirs: Weight: ~120+ lbs Can store ~31 L of liquid oxygen Duration: Up to 8 days at 2 L/min ➡ Advantages: very long usage time, lighter portable units➡ Disadvantages: evaporation loss, more complex, higher costs, fewer suppliers today 3. Small Portable Oxygen Bottles These are mini oxygen tanks used for short travel or temporary outings. Typically weigh 1–3 lbs Last only 20–60 minutes depending on flow Cost around $20–$50 each ➡ Mostly used for emergencies or quick trips—not for long-term oxygen therapy. Pros and Cons of Oxygen Tanks Advantages Delivers very pure oxygen Works without electricity Good for emergency backup Low initial equipment cost Disadvantages Heavy and inconvenient to carry Must be refilled frequently Limited use time—oxygen can run out anytime Safety concerns with high pressure Not ideal for travel or long daily use What Is a Portable Oxygen Concentrator? A portable oxygen concentrator (POC) takes air from around you, filters out nitrogen, and delivers oxygen continuously or in pulses. Since it creates oxygen instead of storing it, you don’t need tank refills. Modern users love POCs—especially an oxygen concentrator with battery—because you can walk, travel, and live freely without worrying about running out of oxygen. Types of Portable Oxygen Concentrators 1. Pulse-Flow Portable Oxygen Concentrators Small, lightweight (2–5 lbs), great for active users. 2. Continuous-Flow Portable Oxygen Concentrators Heavier (5–10 lbs), but essential if you need steady oxygen flow, especially during sleep. Important Specs You Should Know Flow Rate: 1–6 pulse settings 1–2 L/min continuous flow Oxygen Purity: 90% ± 3% Battery Life: 2–6 hours per battery Weight: 2–10 lbs depending on model Noise Level: 38–45 dB (similar to a quiet home) Popular Portable Oxygen Concentrator Brands Inogen (Rove 6, G5) CAIRE (Freestyle Comfort, Eclipse 5) Philips Respironics OxyGo GCE Zen-O Hidgeem (SJ-OX1C) – a compact oxygen concentrator with battery popular for home and travel use Pros & Cons of Portable Oxygen Concentrators Advantages Never run out of oxygen Lightweight and designed for mobility Perfect for travel (including airplanes) Long battery life with swappable batteries Great for long-term oxygen therapy Disadvantages Depend on electricity/battery Upfront cost is higher Continuous-flow POCs are heavier Not suitable for patients needing very high oxygen flow Who Should Choose an Oxygen Tank? Choose an oxygen tank if: You need very high flow rates (over 4 L/min) You mostly stay at home You want a reliable backup during power outages You don’t move around much during the day You don’t travel often Who Should Choose a Portable Oxygen Concentrator? Choose a portable oxygen concentrator (especially an oxygen concentrator with battery) if: You want mobility and independence You travel often You need oxygen many hours a day You don’t want to deal with refills You prefer a lightweight, modern device You want long-term, cost-efficient oxygen support Most people say a POC lets them “get their life back.” Final Comparison: Oxygen Tank vs Portable Oxygen Concentrator Feature Oxygen Tank Portable Oxygen Concentrator Oxygen Source Stored oxygen Generates oxygen Refills Required No refills Weight 3–50+ lbs 2–10 lbs Travel Friendly Limited Excellent Cost Long-Term Higher (refills) Lower Battery Needed No Yes Suitable For Home, high-flow use Daily mobility & travel Final Thoughts Both an oxygen tank and a portable oxygen concentrator have their place in oxygen therapy. But if freedom, mobility, and convenience matter to you, a portable oxygen concentrator with battery is usually the best long-term choice.  

If you’re a senior using a portable oxygen concentrator, or you’re helping an elderly family member use one, the most important thing we can do is stay informed and stay safe. With the right habits, portable oxygen for seniors can greatly improve daily comfort, mobility, and confidence. Below is a complete safety guide based on what we always recommend to our customers. 1. Always Track Your Blood Oxygen With an Oximeter One of the most important tools you should have at home is a pulse oximeter. It allows you to check your blood oxygen (SpO₂) anytime. Here are the basic rules you should follow: SpO₂ above 95% → generally normal SpO₂ between 90%–94% → pay attention, rest, breathe deeply, and measure again SpO₂ below 90% → this is considered low; you should use oxygen immediately and contact a doctor if it does not improve Most seniors should check their oxygen 2–3 times a day, especially in the morning, before activities, and whenever you feel tired or short of breath. If your health condition is less stable, check more frequently. 2. Use the Correct Flow Setting Never change your oxygen flow rate without medical advice. If you feel breathless even at your usual setting, it’s safer to call your doctor rather than increase it on your own. 3. Stay Away From Flames and Heat Oxygen is not flammable by itself, but it feeds fire. Always keep your portable oxygen concentrator away from: candles, gas stoves, fireplaces cigarettes or vaping heaters or hot surfaces Keep a safe distance of at least 6–8 feet. 4. Keep Your Tubing Clean and Safe To avoid tripping and obstruction: Make sure the tubing is not bent or twisted Keep it away from sharp edges If using long tubing, secure it against walls or floors 5. Charge Your Batteries Before Going Out We all love the freedom a portable oxygen concentrator gives us. To stay safe outside: Fully charge before leaving Carry a spare battery if possible Bring your car charger for longer trips 6. Clean and Maintain Your Device Regularly Clean nasal cannulas every week and replace them every 2–4 weeks.Wash or wipe your filters weekly depending on your model. 7. Monitor Oxygen Purity After 1 Year of Use All portable oxygen concentrators rely on molecular sieves to produce oxygen. After about 12 months, many machines begin to show a gradual decline in oxygen purity. This is why seniors should: Check oxygen purity regularly (many devices display it) Notice if breathing feels less effective Replace the molecular sieve when purity drops For long-term safety, it’s essential to choose a portable oxygen concentrator with replaceable molecular sieves. If a machine cannot replace the sieve, the entire device becomes useless once purity declines. 8. Pay Attention to Beeps and Alerts If your concentrator alarms, stop and check the cause—it may be low battery, low purity, or airflow blockage. 9. Listen to Your Body If you feel unusual chest tightness, dizziness, or fatigue, check your SpO₂ immediately and adjust your oxygen use as your doctor recommends. With the right habits and a reliable device, portable oxygen for seniors can help you breathe easier and live more freely every single day.

When we talk about oxygen therapy for lungs, having precise, data‑backed information matters. Oxygen is powerful — too little, and you risk organ damage; too much, and you might worsen other issues like CO₂ retention. Here’s a clear, clinically informed guide to which devices make sense at different levels of lung disease, and how long you should reasonably be on oxygen. When Is Oxygen Therapy Needed? The Numbers That Guide Decisions Long-term oxygen therapy (LTOT) is typically indicated when PaO₂ ≤ 55 mmHg or SpO₂ ≤ 88% at rest on room air. This is widely used in clinical trials and is referenced by Medicare coverage policies. For borderline cases (PaO₂ of 56–59 mmHg or SpO₂ ~89%) plus evidence of pulmonary hypertension, cor pulmonale, or elevated red blood cell count, supplemental oxygen may also be justified. In some patients, resting oxygen is fine, but during exercise or a 6‑minute walk test, their SpO₂ drops to ≤ 88%. In those cases, ambulatory oxygen is often used. During acute or hospital settings, typical SpO₂ targets are 90–94% for most patients; but for COPD patients at risk of CO₂ retention, the safer target is often 88–92%. How Much Oxygen Time Is Actually Recommended? It depends on severity — not everyone needs 15 hours per day. Here’s a realistic breakdown: Lung Impairment Typical Indication Recommended Oxygen Use Duration Mild Resting SpO₂ ≥ 89%, but desaturates on exertion to ≤ 88% Use mainly during activity or exertion; no need for 15‑hour/day oxygen therapy. Many patients use a portable oxygen concentrator only when walking, climbing stairs, or during exercise. Moderate Resting SpO₂ ~85–88%, or frequent desaturation with activity Consider continuous or high-flow oxygen for part of the day. Some guidelines or clinicians may target 8–12 hours/day (or more) depending on symptoms, but not everyone needs full 24‑hour therapy. Severe Resting SpO₂ ≤ 88% (or PaO₂ ≤ 55 mmHg) on room air Long-Term Oxygen Therapy (LTOT) research supports ≥ 15 hours/day (many recommend 15–24 hours) to reduce mortality and improve outcomes. And the patients need 5L or 10L big heavy medical oxygen concentrator. Oxygen Delivery Devices — Strengths & Trade‑offs 1. Oxygen Tanks (Compressed or Liquid) Strengths: High purity oxygen, capable of very high flow. Good as a stationary or backup source. Limitations: Heavy, difficult to carry, require refills, risk of pressure hazard. Best used for: Patients who need high flow or continuous high‑flow oxygen, or as a backup for emergencies. 2. Home Oxygen Concentrators Strengths: Unlimited oxygen when plugged in, no refills, relatively cost‑effective over time. Limitations: Bulky, not portable, dependent on power. Ideal for: Patients with moderate or severe lung disease who need oxygen for many hours per day (e.g., LTOT users). 3. Portable Oxygen Concentrators (POCs) Strengths: Lightweight, battery‑powered, great for mobility. Some are pulse flow portable oxygen concentrator, others provide continuous flow. Limitations: Battery life varies; pulse-flow POCs may not work well for people who need oxygen during sleep or rest. Best for: Patients with mild to moderate disease, or those who desaturate primarily during activity. Matching Device to Severity: Practical Guidance Mild Lung Disease:Use a pulse-flow or continuous-flow POC during activity. Because your resting SpO₂ is typically okay, you're not likely to need oxygen 15 hours a day. The goal is maintaining safe oxygen when you are active, especially if exercise causes desaturation. Moderate Lung Disease:Consider a combination: a home concentrator when you are at rest or at home, and a continuous-flow POC when you go out or need portable support. Use your oxygen for several hours each day, based on your prescription and symptom profile. Severe Lung Disease:Use LTOT via a home concentrator for the bulk of the day (≥ 15 hours), according to evidence from long-term outcome trials. Use a portable concentrator or oxygen tank as backup or for mobility when needed. Safety & Monitoring Tips Regularly check your SpO₂ with a pulse oximeter to ensure you're meeting your target range. Avoid “over-oxygenating”: if your SpO₂ rises above your target (for example, > 94% in people at risk of CO₂ retention), consult your doctor — too much oxygen can be harmful. For mobile POCs, carry extra batteries if needed; choose a device whose battery life aligns with how often you plan to use it. Final Thoughts Oxygen therapy for lungs isn’t “one size fits all.” The device and time you need depend on how low your oxygen is, how often it drops, and what your daily activities look like. If your SpO₂ is only low during exertion (mild disease), you won’t need to run oxygen 15 hours a day. For more severe disease, long-term use (≥ 15 hours/day) has proven benefits in mortality and symptom control. Talk to your clinician, use objective tests (like oximetry or ABG), and choose a device that matches your oxygen needs, your lifestyle, and your target SpO₂.

If you’re living with a respiratory condition like COPD, you might be wondering: Do I need a continuous flow or pulse flow oxygen device? Choosing the right oxygen therapy can make a huge difference in your energy, sleep, and overall quality of life. Let’s break it down together. Continuous flow oxygen delivers a steady stream of oxygen all the time, which is especially important if you need oxygen while sleeping, exercising, or during daily activities. Pulse flow oxygen only gives oxygen when you inhale, which can work for people who need supplemental oxygen occasionally during the day. To figure out which option is right for you, you first need to understand your oxygen requirements. A pulse oximeter can help you monitor your blood oxygen levels. If your oxygen drops significantly during sleep or activity, continuous flow is usually safer. For those of us looking for convenience and mobility, a portable oxygen generator or oxygen portable machine can be a game changer. You are not going to be tied by the cables if use portable oxygen generator, even from bedroom to the kitchen. Our SJ-OX1C continuous flow portable oxygen concentrator is lightweight, quiet, and designed to give you reliable oxygen wherever you go—it’s truly oxygen to go. Many of our customers love it because they can move freely around the house or even take it on trips without worrying about missing a breath. However, it’s important to be realistic. If you are a severe COPD patient or have advanced lung cancer, your oxygen needs are much higher. You may require 5L or 10L medical-grade oxygen machines to maintain adequate oxygenation. This kind of oxygen machine usually is big and heavy. For these cases, a health-focused portable oxygen machine like the SJ-OX1C simply won’t deliver enough oxygen. Our device is best suited for home users or those with moderate oxygen requirements who want a safe, portable solution. Always consult your doctor before making a decision, they can guide you on the right flow rate and type of oxygen therapy. But if you need a flexible, convenient option for daily life or light travel, a continuous flow portable oxygen generator like the SJ-OX1C is a reliable choice. With the right oxygen device, you can breathe easier, stay active, and enjoy life more fully.

If you or someone in your family uses a home oxygen concentrator, it’s natural to wonder whether it’s safe to keep using it around your pets. Many households have both oxygen users and beloved cats, dogs, or birds. But can a portable oxygen generator affect your pet’s health — or could pets even use oxygen therapy themselves? Let’s clear up the confusion with some science-based answers. How a Home Oxygen Concentrator Works A home oxygen machine draws in surrounding air, filters out nitrogen, and delivers concentrated oxygen (usually 90–96%) to the user through a tube or mask.Unlike traditional oxygen tanks, it doesn’t store compressed gas; instead, it produces oxygen continuously using a molecular sieve (usually zeolite).This process is clean, chemical-free, and safe for use in homes with people and animals. Is It Safe to Use an Oxygen Concentrator Around Pets? ✅ Yes, it’s safe.A concentrator only filters air — it doesn’t release any toxic gases, odors, or harmful chemicals. Cats, dogs, and other small pets can stay in the same room as the device without health risks. However, here are some practical tips: Keep cords and tubing out of reach — curious pets might chew them. Ensure the air vents are not blocked by fur, pet beds, or toys. Some pets may need time to get used to the gentle hum of the machine. Modern portable oxygen machines such as the Hidgeem SJ-OX1C operate at under 42 dB — quiet enough even for sensitive pets. Can Pets Use Oxygen Therapy Too? Surprisingly, yes — but only under veterinary supervision.Veterinarians often use pet oxygen machines or oxygen cages to treat animals suffering from: Respiratory infections Heart or lung disease Smoke inhalation or trauma Post-surgery recovery In these cases, oxygen therapy can literally save a pet’s life.But it’s important to understand that pet oxygen concentrators are not the same as human ones. Pet Oxygen Machine vs. Human Oxygen Concentrator: What’s the Difference? Feature Human Oxygen Concentrator Pet Oxygen Machine Oxygen Flow Type Continuous or pulse flow (1–5 L/min) Continuous flow, usually low pressure Oxygen Purity 90–96% 90–95%, but with adjustable airflow suitable for small lungs Output Pressure Higher (30–70 kPa) to meet adult breathing needs Lower (10–30 kPa) to prevent over-oxygenation Delivery Method Nasal cannula or mask for humans Oxygen cage, tent, or small-animal mask Design Focus Compact, portable, noise control Stable temperature, safe for enclosed spaces Cost $300–$800 $400–$1,000 depending on size and accessories Can You Use a Human Oxygen Machine for Pets? It’s not recommended to use your personal home oxygen concentrator directly on pets.Here’s why: Flow pressure is too high.Most home concentrators are designed for human lung capacity. Small pets can easily receive too much oxygen, which may damage their lungs or lead to oxygen toxicity. No way to regulate animal-specific airflow.A pet’s safe oxygen flow may range between 0.1–1 L/min, far lower than human devices provide. Mask size and fittings differ.Human cannulas and masks won’t seal properly on animals, leading to uneven oxygen delivery or CO₂ buildup. Temperature and humidity control.Veterinary oxygen chambers maintain comfortable airflow for small animals — something regular portable oxygen machines can’t do safely. If you think your pet needs oxygen therapy, the safest choice is to consult a veterinarian and let them prescribe a pet-specific oxygen generator or cage system. Tips for Oxygen Users Living with Pets Even if your pets don’t need oxygen therapy, it’s smart to maintain a safe environment: Place your concentrator in a stable, well-ventilated area. Clean intake filters regularly to prevent pet hair buildup. Train your pets not to play with the tubing. If you travel, choose a portable oxygen generator that’s lightweight, quiet, and easy to move between rooms. Final Thoughts Oxygen concentrators and pets can coexist safely — as long as you use the equipment correctly.Your home oxygen machine won’t harm your pets, but it’s not suitable for direct veterinary use. For pets needing oxygen therapy, specialized pet oxygen machines or oxygen cages are the right choice. Both humans and animals deserve clean, reliable oxygen — just make sure each has the right equipment for their needs.

Owning a portable oxygen concentrator or oxygen machine portable is a big step toward independence, whether you need supplemental oxygen for medical reasons or want support during travel and daily activities. But like any medical device, a portable oxygen generator works best when properly cared for. Regular maintenance ensures your oxygen concentrator delivers consistent oxygen flow and prolongs the life of key components such as molecular sieves, batteries, filters, and nasal cannulas. Let’s go through a simple daily, weekly, and monthly maintenance checklist for your continuous flow portable oxygen concentrator. How a Portable Oxygen Concentrator Works Before diving into maintenance, it’s useful to understand the basics. A portable oxygen generator pulls in ambient air and separates oxygen from nitrogen using molecular sieve tube. The device compresses air, traps nitrogen in the zeolite sieve, and delivers concentrated oxygen through a nasal cannula. Continuous flow oxygen concentrators supply a steady stream of oxygen, while pulse flow units deliver oxygen only when you inhale. Proper maintenance ensures your oxygen machine continues to function at peak performance. Daily Care Check the battery – Make sure the battery in your oxygen machine portable is fully charged. Low battery levels can reduce oxygen flow or interrupt therapy. Inspect the nasal cannula – Check for bends, cracks, or discoloration. Replace as needed, typically every 1–2 weeks depending on usage. Monitor alarms – Modern continuous flow portable oxygen concentrators, like the Hidgeem SJ-OX1C, alert you to low oxygen output, battery issues, or airflow problems. Never ignore them. Clean the exterior – Wipe down your oxygen generator with a soft, damp cloth to remove dust. Avoid harsh chemicals that could damage the device. Weekly Care Clean or replace filters – Many portable oxygen concentrators have reusable foam filters. Rinse weekly with mild soap and water and dry completely. Replace disposable filters according to manufacturer instructions. Check tubing connections – Ensure all hoses and adapters are securely connected to prevent leaks and maintain consistent oxygen delivery. Monthly Care Inspect molecular sieve beds – The zeolite material in your molecular sieve can absorb moisture over time, reducing oxygen output. If you notice decreased oxygen concentration, unusual sounds, or frequent alarms, the sieve may need replacement. High-quality sieves in devices like Hidgeem SJ-OX1C can last thousands of hours but should still be monitored regularly. Battery health check – Rechargeable batteries degrade over time. Shorter run times may indicate it’s time for a replacement. Replace nasal cannulas and tubing if worn out or discolored. Inspect filter housing and vents – Dust buildup can reduce airflow. Clean gently using a soft brush or vacuum attachment. General Tips Keep your oxygen generator in a dry environment to protect molecular sieves from moisture. Ensure proper ventilation during operation; don’t cover the device while it’s running. Follow manufacturer recommendations for sieve bed, filter, and battery replacement to maintain consistent oxygen flow. Schedule professional servicing annually or as recommended by your supplier.   If there is any question of the maintenance of your oxygen concentrator, you are welcome to call us for assistance: +1 (833) 443 4336.

Have you ever wondered how a portable oxygen concentrator (POC) can take in regular air and turn it into pure, medical-grade oxygen? It almost feels like magic — but it’s actually smart science. At the heart of every oxygen concentrator is a key component called a molecular sieve, and it’s the reason you can get a steady flow of oxygen wherever you go.   What Is a Molecular Sieve? A molecular sieve is a material made from zeolite, a naturally occurring or synthetic mineral known for its unique structure. Zeolite crystals contain millions of microscopic pores that can separate gases based on their molecular size. In the case of an oxygen concentrator, these pores are the key to removing nitrogen from the air. Since normal air is about 78% nitrogen and only 21% oxygen, your concentrator needs a way to extract just the oxygen. That’s exactly what the molecular sieve does — it “grabs” nitrogen molecules and holds them inside its tiny pores, while allowing oxygen molecules to pass through freely.   How Molecular Sieves Work Inside an Oxygen Concentrator Here’s a simplified version of the Pressure Swing Adsorption (PSA) process used in most oxygen concentrators: Air Intake – The machine pulls in ambient air through a filter. Compression – The air is lightly compressed and directed into one of the molecular sieve beds. Nitrogen Adsorption – The zeolite material captures nitrogen molecules, effectively separating them from the oxygen. Oxygen Delivery – The purified oxygen is stored briefly and delivered to you through the nasal cannula. Regeneration Cycle – The concentrator releases the trapped nitrogen and regenerates the sieve bed for the next cycle. This process repeats continuously — switching between two or more sieve beds — so that oxygen production never stops.   Continuous Flow vs. Pulse Flow and the Role of the Sieve Depending on your oxygen therapy needs, concentrators can operate in pulse flow or continuous flow modes. Pulse flow units deliver oxygen only when you inhale, saving energy and extending battery life. Continuous flow models supply oxygen non-stop, which is especially useful for nighttime use or patients with irregular breathing patterns. In both cases, the molecular sieve’s efficiency determines the purity level of oxygen, which typically ranges between 90% and 96%. High-quality sieve materials ensure stable oxygen output and longer device life.   Why Molecular Sieve Quality Matters Not all molecular sieves are created equal. Over time, lower-quality zeolites can lose their adsorption capacity, leading to reduced oxygen concentration. Premium-grade zeolites — like those used in medical-grade concentrators — can maintain stable oxygen output for thousands of hours with minimal degradation.   How to Maintain the Molecular Sieve One thing many people don’t realize is that the molecular sieve inside your oxygen concentrator is very sensitive to moisture. The zeolite material used in the sieve has tiny pores that trap nitrogen — but those same pores can also absorb humidity from the air. Over time, if moisture gets inside, the zeolite becomes less effective at separating nitrogen, and as a result, your oxygen purity and flow rate may gradually drop. To prevent this, it’s important to keep your oxygen concentrator in a dry, well-ventilated environment, away from damp areas like bathrooms or kitchens. Always make sure the air filters are clean so the airflow remains smooth and dust-free. If you live in a humid region, using a dehumidifier nearby can help extend the life of the molecular sieve. After long-term use, it’s normal for the oxygen output to slowly decrease — this usually means the sieve beds are saturated and need replacement or maintenance. Taking good care of your concentrator not only keeps it running efficiently but also ensures that you always get the steady, reliable oxygen support you need.   When to Replace the Molecular Sieve Like any core component, the molecular sieve in your oxygen concentrator won’t last forever. Even with good maintenance, the zeolite material gradually loses its adsorption capacity after thousands of hours of operation. This means it becomes less effective at capturing nitrogen, which can cause a slow decline in oxygen purity. Most home and portable oxygen concentrators have a sieve lifespan of about 8,000 to 12,000 hours of use — roughly two to three years for regular users. However, factors like humidity, temperature, and continuous use can shorten this time. Hidgeem’s  SJ-OX1C portable oxygen machine is designed with replaceable molecular sieve beds, so you don’t need to replace the whole machine when performance starts to drop. You can simply have the sieve beds changed or serviced by an authorized technician to restore your concentrator’s oxygen purity back to optimal levels. By replacing the sieve at the right time, you’ll extend the life of your portable oxygen machine and continue to enjoy clean, concentrated oxygen — whether you’re at home, traveling, or sleeping at night.
