    Altro da scoprire — i concentratori Drive DeVilbissFissi da 5 e 10 LPM, più il portatile iGo
    Due usi diversi, non due fasce di prezzo.
    Il 525DS e il 1025DS sono apparecchi fissi: si collegano alla presa e restano lì, con flusso continuo fino a 5 e 10 litri al minuto. L’iGo è quello portatile — a batteria e abbastanza piccolo da portarlo davvero fuori casa. I portatili funzionano in modo diverso dagli apparecchi fissi, e se uno fa al caso Suo dipende dal flusso impostato dal Suo medico: non è semplicemente la versione più piccola della stessa cosa. Ci dica quel valore e se deve uscire di casa con l’apparecchio, e Le diremo quale di questi fa al caso Suo. Spesso la risposta onesta è entrambi: uno che funziona tutta la notte a casa e uno che va in auto.
    • Nessuna prescrizione necessaria
    • 525DS — fino a 5 LPM, fisso
    • 1025DS — fino a 10 LPM, fisso
    • iGo — portatile, a batteria

    Ci chiami e ci dica il flusso impostato dal Suo medico — quel solo numero risponde a quasi tutto, e da parte nostra non serve alcuna pratica. Le diremo quale apparecchio lo copre, quanto costa e se Le serve anche un portatile per uscire di casa. Molte persone hanno bisogno di entrambi, e molte se li vedono vendere entrambi quando ne sarebbe bastato uno. Se non è sicuro del Suo flusso, Le diremo cosa chiedere.

    DEVILBISS 525DS 5 LITER HOME OXYGEN CONCENTRATOR OVERVIEW

    If you've just been prescribed home oxygen therapy — whether for COPD, pulmonary fibrosis, post-COVID lung complications, congestive heart failure, or recovery from major surgery — you probably have a lot of questions right now. And maybe some fear. That's completely normal. Oxygen therapy is one of the most fundamental things medicine can offer: helping you breathe.

    Here's what nobody tells you at the doctor's office: when breathing becomes work, everything else in your day becomes harder. Climbing stairs. Eating meals without getting winded. Sleeping through the night. Having a full conversation. A lot of people delay starting oxygen therapy because they're worried it means "giving up" or being tethered to a machine. It's actually the opposite. Proper oxygen therapy dramatically restores your energy, your sleep, and your ability to actually enjoy your day. Patients often describe the first few days on prescribed oxygen as "finally being able to think clearly again."

    The DeVilbiss 525DS 5 Liter Home Oxygen Concentrator is the best-selling home oxygen concentrator in the U.S. for a reason. Made in Pennsylvania by Drive Medical (DeVilbiss brand), it delivers up to 5 liters per minute of continuous, medical-grade oxygen — quietly (48 dBA, quieter than a normal conversation), efficiently (patented Turn-Down Technology cuts electricity use by 15%+), and reliably (3-year manufacturer warranty and a <3% warranty-failure rate). The built-in Oxygen Sensing Device (OSD) continuously monitors purity and alerts you if levels drop — so you and your caregivers always know the therapy is working.

    What you're really buying isn't equipment. It's the difference between gasping for breath climbing your stairs and walking your grandkids to the park. Between waking up exhausted every morning and actually sleeping through the night. Between saying no to dinner with friends because you're too tired and saying yes to your life again.

    Patented Turn-Down Technology Lower power bills + longer machine life
    Most oxygen concentrators run at full compressor pressure regardless of your flow rate — wasting electricity and wearing out internal components. The 525DS's patented Turn-Down Technology automatically reduces internal pressure by 35% when you're on flow settings of 2.5 LPM or lower (where most patients spend most of their time). Result: 15% or more reduction in electricity consumption (average $100+ per year in energy savings) and significantly longer compressor life. Over the 3-year warranty period alone, that's around $300 in electricity you don't spend — plus a machine that lasts longer past the warranty. Real money, not marketing.
    🇺🇸 Made in USA Assembled in Pennsylvania · Less than 3% warranty failure rate
    The 525DS is proudly built in the USA by Drive Medical / DeVilbiss Healthcare. Independent studies show a warranty-failure rate below 3% — remarkably reliable for daily-use medical equipment. The rotary valve is tested to 10 million cycles (about 25,000 hours of use). This is why it's the best-selling home oxygen concentrator in its class.

    CONTINUOUS-FLOW OXYGEN THAT ACTUALLY FITS INTO YOUR HOME

    Think about what your day looks like right now with breathing that's a struggle: getting out of bed takes effort, walking to the kitchen leaves you winded, showering exhausts you, stairs feel impossible, and you're too tired to enjoy anything. A properly-sized home oxygen concentrator changes that. The DeVilbiss 525DS delivers a continuous stream of medical-grade oxygen (up to 5 LPM) through your nasal cannula, so you get the oxygen your body needs during every breath — whether you're sleeping, resting, watching TV, or moving around the house. The rolling casters + top and side handles mean you can easily move the machine from room to room. The 48 dBA sound level (quieter than normal conversation) means it won't disrupt sleep or wake your family. The recessed humidifier bottle nook lets you add humidity to the oxygen (important for many patients — dry oxygen irritates the nasal passages), and the lockable flow meter prevents accidental adjustment if you have small children or grandchildren in the house. The OSD (Oxygen Sensing Device) continuously monitors purity and alarms if it drops below 85% — you always know the therapy is working. And Drive Medical's 3-year warranty means if anything goes wrong, we've got you covered.

    A great fit for:
    • You've been prescribed home oxygen therapy (COPD, pulmonary fibrosis, post-COVID complications, CHF, post-surgical recovery) and need a reliable stationary concentrator for daily use at home
    • Your prescription is for a continuous flow at any rate from 0.5 to 5 LPM — the 525DS handles the full range with a lockable, precise flow meter
    • You want a proven, reliable machine — the 525DS is the best-selling home concentrator in the U.S. with a documented under-3% failure rate
    • You're worried about electricity costs — the Turn-Down Technology can save $100+ per year on a machine that runs 24/7
    • You want quiet operation for sleeping and daytime use — 48 dBA is quieter than most household appliances
    • You value American-made medical equipment with a solid 3-year warranty and reliable service network

    KEY FEATURES
    What you'll notice
    (in daily use)
    FeatureWhat it really means for you
    💨
    Continuous flow 0.5 – 5 LPM
    Adjustable in 0.5 LPM increments
    Delivers a constant stream of oxygen through your nasal cannula — not pulse-dose. Every breath gets oxygen, whether you're sleeping, resting, or moving. Adjustable to match your exact prescribed flow rate.
    🧪
    87–93% oxygen purity
    Medical-grade concentration
    Meets the medical-grade threshold for effective oxygen therapy (Medicare requires ≥85% for coverage). The concentrator pulls nitrogen out of the room air and delivers concentrated oxygen to you.
    🛡️
    OSD (Oxygen Sensing Device)
    Continuous purity monitoring
    Built-in sensor continuously monitors output purity. If levels drop below 85%, a visual and audible alarm alerts you and your caregivers so you always know the therapy is working. Peace of mind that's not marketing.
    ⚡
    Patented Turn-Down Technology
    Auto-reduces pressure at low flows
    Automatically drops internal pressure 35% when you're on flow settings of 2.5 LPM or lower. Cuts electricity use by 15%+ (about $100/year in savings) and extends the compressor life. Real savings on a machine that runs 24/7.
    🔇
    48 dBA quiet operation
    Quieter than a normal conversation
    For reference: a normal conversation is ~60 dB. A refrigerator hum is ~50 dB. The 525DS runs at 48 dBA — quiet enough to sleep next to. The two-piece cabinet is specifically designed for sound reduction.
    🔒
    Lockable flow meter
    Prevents accidental adjustment
    Once your doctor sets your prescribed flow rate, the flow meter locks in place. Kids, grandkids, and confused adults can't accidentally change the setting — an important safety feature for many households.
    💧
    Recessed humidifier bottle nook
    Add humidity to prevent nose dryness
    Many patients need humidified oxygen — dry oxygen irritates nasal passages, especially at higher flow rates. The recessed nook protects the humidifier bottle from accidental knocks and makes daily water changes easy.
    🛞
    Rolling casters + carry handles
    Easy room-to-room movement
    Sturdy top grab handle plus recessed side handles for easy lifting when needed (36 lb total weight). Smooth-rolling casters glide over carpet, hardwood, and tile so you can move the concentrator from bedroom to living room without help.
    🔧
    Two-piece cabinet design
    Easier maintenance access
    The cabinet splits in two for filter changes and internal maintenance — no complex disassembly required. Reduces service costs and downtime if maintenance is ever needed.
    🚨
    Comprehensive alarm system
    Audible + visual alerts
    High/low pressure alarms, low flow alarm, low oxygen alarm, power failure alarm, OSD purity alarm. All alarms have both audible and visual signals so you and caregivers can respond quickly to any issue.
    🇺🇸
    Made in USA (Pennsylvania)
    Assembled by Drive Medical
    Built in the USA using US and quality imported parts. The rotary valve is tested to 10 million cycles (~25,000 hours). Documented warranty-failure rate below 3% — exceptional for daily-use medical equipment.
    🏆
    3-year manufacturer warranty
    Industry-standard best
    Drive Medical's 3-year warranty is one of the best available in this category. Covers manufacturing defects and premature failure under normal home use. Excludes filters and consumables.
    WHY WE RECOMMEND IT
    What makes the 525DS the right pick
    (at a glance)
    It's the best-selling home oxygen concentrator in the U.S. for a reason:Reliability data doesn't lie — under 3% warranty-failure rate, rotary valve tested to 10 million cycles. When something you rely on 24/7 has to work, you want the proven platform.
    Turn-Down Technology is a real, measurable feature:Not marketing fluff — the 15% power reduction at flow rates under 2.5 LPM saves an average of $100/year on your electric bill. Over 3 years of ownership, that's $300 in real savings.
    The OSD (Oxygen Sensing Device) gives peace of mind:Continuous purity monitoring with audible/visual alarms means you're never wondering "is this actually working?" — you'll know instantly if something's wrong.
    48 dBA is genuinely quiet for a 5L concentrator:Many older concentrators are 55–65 dBA — loud enough to disrupt sleep. The 525DS's two-piece sound-dampening cabinet keeps it quieter than a normal conversation. Sleep-friendly.
    36 lb with quality rolling casters is genuinely movable:Not truly "portable" (that requires a POC — portable oxygen concentrator), but very easy to move from bedroom to living room, or between floors with help. Top and side handles make lifting manageable.
    Full range of flow rates (0.5 – 5 LPM) with 0.5 LPM increments:Covers essentially every prescribed oxygen dose. The lockable meter prevents accidental changes — important for households with kids or dementia patients.
    Made in USA with a 3-year warranty:Assembled in Pennsylvania. Parts and service network are established and accessible. 3-year warranty is best-in-class for this category (many competitors offer only 1–2 years).

    WHAT'S INCLUDED
    525DS package
    (what arrives in the box)
    What is included with your purchase:
    DeVilbiss 525DS 5L Oxygen Concentrator Unit:Assembled and ready to use — plug in, set the flow rate, attach your cannula, and start therapy
    Power Cord:Grounded AC power cord for standard 120V home outlets
    Owner's Manual:Complete operating instructions, safety information, maintenance schedule, and warranty registration
    Accessories sold separately The 525DS does NOT include an oxygen mask, nasal cannula, extension tubing, humidifier bottle, or distilled water. You'll need these accessories to actually use the concentrator. See the Accessories section below for options, or call us at (713) 695-4939 and we'll help you assemble the right starter package for your prescription.
    ESSENTIAL ACCESSORIES
    What you'll need to actually use the concentrator
    (call for current pricing)
    Nasal Cannula (Required):Two small prongs that deliver oxygen directly into the nostrils. Available in various lengths (typically 4–25 feet). Should be replaced every 2–4 weeks for hygiene. Most patients start with a 7-foot cannula for good in-room movement.
    Extension Tubing (Recommended):Flexible tubing that connects to the cannula and extends your reach. Available in 7, 14, 25, and 50-foot lengths. Longer tubing = more freedom to move around the room or floor while stayin' on oxygen. Choose based on your home layout.
    Oxygen Mask (Alternative to Cannula):Covers nose and mouth for higher flow oxygen delivery. Prescribed for some patients who can't tolerate cannulas or need higher concentrations. Your doctor will specify if a mask is appropriate.
    Humidifier Bottle (Recommended):Attaches to the recessed nook on the 525DS. Adds humidity to the oxygen stream — strongly recommended if you're on flow rates above 2 LPM because dry oxygen irritates nasal passages and can cause nosebleeds. Standard humidifier bottle fits the 525DS.
    Distilled Water (for Humidifier Bottle):Only distilled water — NEVER tap water. Tap water leaves mineral deposits that clog the humidifier and can contaminate the oxygen stream. Distilled water keeps everything clean and safe. Change daily.
    Pulse Oximeter (Highly Recommended):Small clip-on device for your fingertip that reads your blood oxygen saturation (SpO2) and heart rate. Essential for anyone on oxygen therapy — lets you verify the therapy is working and know if your levels drop. Under $30 for a good fingertip model.
    Replacement Cabinet Filter:The 525DS has a washable/replaceable air intake filter. Should be cleaned weekly and replaced periodically. We stock replacements.
    Call for a starter package quote: Most first-time oxygen therapy patients need: concentrator + 2 cannulas + 25 ft tubing + humidifier bottle + pulse oximeter + case of distilled water. Call (713) 695-4939 and we'll put together a starter package based on your prescription and home layout.

    FAQs
    Common questions before ordering
    (prescription · accessories · usage · coverage)
    Do I really need a prescription to buy an oxygen concentrator?
    Yes — federal law requires a valid prescription from a licensed physician, pulmonologist, or respiratory therapist to purchase any home oxygen concentrator, including the 525DS. This isn't a bureaucratic hurdle — it's a safety requirement. Oxygen therapy at the wrong flow rate can be dangerous (too low = ineffective; too high = can suppress your breathing drive, especially for COPD patients). Your doctor determines the correct flow rate based on your specific condition, blood oxygen levels, and other factors.

    The prescription must specify your flow rate (LPM setting), hours per day of use, and whether oxygen is prescribed for continuous or as-needed use.

    How to send us your prescription:
    • Fax: Call (713) 695-4939 for our fax line
    • Email: Have your doctor's office email us the Rx
    • In-store: Bring the paper prescription to our Houston showroom
    • Doctor-direct: Ask your doctor's office to fax/call us on your behalf

    Don't have a prescription yet? Talk to your doctor first — never use oxygen therapy without medical supervision. Incorrect flow rates can be dangerous. Call us at (713) 695-4939 and we can walk you through the prescription process.
    What's the difference between continuous flow and pulse dose oxygen concentrators?
    Two very different technologies:

    • Continuous flow (this 525DS): Delivers a constant, steady stream of oxygen through your cannula — whether you're inhaling or exhaling. Every breath gets the same oxygen concentration. Required for nighttime use, ventilators, CPAP/BiPAP with oxygen, and patients with high oxygen needs.

    • Pulse dose (portable units): Detects when you inhale and delivers a "puff" of oxygen only during inhalation. Uses less battery, so it's what makes portable oxygen concentrators (POCs) possible. But delivers less total oxygen per minute — not appropriate for all patients.

    Most patients start on continuous flow (like the 525DS) for home use, and add a pulse-dose portable unit for travel/errands. Your prescription will specify which type you need — don't substitute one for the other without talking to your doctor.
    Can I run the 525DS 24 hours a day, 7 days a week?
    Yes — the 525DS is specifically designed for continuous 24/7 operation. Drive Medical states it can run continuously at any flow setting, 365 days a year. That's exactly what a home oxygen concentrator is for. The rotary valve is tested to 10 million cycles (about 25,000 hours of continuous use, which is nearly 3 years of 24/7 operation), and the 3-year warranty covers you during that time. Turn-Down Technology also helps by reducing wear during lower-flow periods. Just remember to clean the intake filter weekly — that's the main maintenance for round-the-clock operation.
    What happens if the power goes out?
    The 525DS is not battery-powered — it plugs into a standard 120V outlet. If the power goes out, the concentrator stops producing oxygen and the power failure alarm sounds so you know immediately. This is why oxygen-dependent patients should have a backup plan:

    • Backup oxygen tank — a full "E" or "H" size compressed oxygen cylinder as emergency backup (we sell these)
    • Register with your utility — most electric utilities have programs for medical-equipment-dependent customers (priority restoration during outages, sometimes free backup generators)
    • Notify your local fire department — many will keep records of oxygen-dependent residents for emergency response
    • Portable oxygen concentrator (POC) — battery-powered units for extended outages

    Call (713) 695-4939 to discuss backup oxygen options for your situation.
    Do I need a humidifier bottle?
    Strongly recommended, especially if:

    • Your prescribed flow rate is above 2 LPM (dry oxygen at higher flows irritates nasal passages)
    • You experience nose dryness, nosebleeds, or crusting since starting oxygen
    • You live in a dry climate or use central heating in winter (both dry the air further)
    • You'll be on oxygen for extended daily use

    The 525DS has a recessed humidifier bottle nook specifically designed for a standard humidifier bottle. Only use distilled water in the humidifier — never tap water (tap water leaves mineral deposits that clog the bottle and can contaminate the oxygen stream). Change the water daily and clean the bottle weekly. Call us for humidifier bottle options and pricing.
    Is the 525DS covered by Medicare or insurance?
    Yes. Home oxygen therapy is a covered benefit under Medicare Part B with proper documentation — the 525DS carries HCPCS code E1390 (Oxygen concentrator, single delivery port, capable of delivering ≥85% oxygen). Medicare typically covers oxygen therapy as a monthly rental payment (about 36 months) with documented medical necessity, including:

    • Doctor's prescription specifying flow rate and hours per day
    • Blood oxygen test results (arterial blood gas or overnight pulse oximetry) documenting SpO2 ≤88% or PaO2 ≤55 mmHg
    • Diagnosis supporting long-term oxygen therapy (COPD, pulmonary fibrosis, CHF with hypoxemia, etc.)

    Coverage typically runs 80% (Medicare Part B), with the remaining 20% subject to your deductible and any secondary insurance. Medicaid and most private insurers also cover oxygen therapy. Call (713) 695-4939 and we'll help you understand what your specific plan requires and how to submit documentation.
    How loud is 48 dBA, really?
    Here's a reference chart:

    • 30 dB — whisper
    • 40 dB — quiet library, refrigerator hum
    • 48 dB — the 525DS
    • 50 dB — typical office background noise
    • 60 dB — normal conversation
    • 70 dB — vacuum cleaner, older oxygen concentrators

    At 48 dBA, the 525DS is quieter than a normal conversation and only slightly louder than a modern refrigerator. Most patients find they can sleep next to it without issue. The two-piece cabinet is specifically designed for sound damping. If you're sound-sensitive, consider putting the concentrator in an adjacent room and using longer oxygen tubing (25 or 50 ft) to reach your bed — that reduces perceived noise even further.
    What accessories do I need before I can actually use it?
    At minimum, you need:

    • Nasal cannula (2 prongs that go in your nostrils) — required for oxygen delivery
    • Extension tubing — to reach from the concentrator to where you sit/sleep (7–25 ft depending on layout)

    Strongly recommended additions:

    • Humidifier bottle + distilled water (especially at higher flow rates)
    • Pulse oximeter — essential for anyone on oxygen therapy, lets you verify SpO2 is staying in the target range
    • Spare cannulas — replace every 2–4 weeks for hygiene

    Call (713) 695-4939 and we'll build a starter package with everything you need based on your prescription and home layout. Most patients spend $50–$100 on the initial accessories starter kit.
    Can I travel with the 525DS?
    The 525DS is not truly portable — it's designed for home stationary use. At 36 lb, it's movable within your home (rolling casters + handles) but too heavy for regular travel. For travel, you need a Portable Oxygen Concentrator (POC) — a battery-powered unit typically weighing 5–10 lb. POCs are FAA-approved for airline travel, but they typically use pulse-dose delivery (not continuous flow), so your doctor needs to verify a POC is appropriate for your prescription. Many oxygen patients own both: a 525DS at home for 24/7 use, and a POC for travel and errands. Call (713) 695-4939 to discuss portable options if you travel or need mobility outside the home.
    How do I know if it's working correctly?
    Three ways to verify the 525DS is working correctly:

    • OSD (Oxygen Sensing Device) — built into the concentrator, continuously monitors purity. If oxygen output drops below 85%, an audible and visual alarm sounds. No alarms = you're getting proper concentration.
    • Pulse oximeter — clip on your finger, read your SpO2 (blood oxygen saturation) and heart rate. Your doctor will tell you your target range (typically 88–95%). If your SpO2 is in range on the prescribed flow rate, the therapy is working.
    • How you feel — within days of starting properly-prescribed oxygen therapy, most patients report improved energy, better sleep, less shortness of breath during daily activities, and clearer thinking. If you don't feel better after the first week, talk to your doctor — the flow rate may need adjustment.

    Also do the basics: keep the intake filter clean (rinse weekly, replace as needed), check that the flow meter shows the prescribed setting, verify the humidifier bottle water is fresh, and inspect the cannula for kinks or damage.

    About this product — Quick answers
    FAQs
    Common questions before ordering
    (prescription · accessories · usage · coverage)
    Do I really need a prescription to buy an oxygen concentrator?
    Yes — federal law requires a valid prescription from a licensed physician, pulmonologist, or respiratory therapist to purchase any home oxygen concentrator, including the 525DS. This isn't a bureaucratic hurdle — it's a safety requirement. Oxygen therapy at the wrong flow rate can be dangerous (too low = ineffective; too high = can suppress your breathing drive, especially for COPD patients). Your doctor determines the correct flow rate based on your specific condition, blood oxygen levels, and other factors.

    The prescription must specify your flow rate (LPM setting), hours per day of use, and whether oxygen is prescribed for continuous or as-needed use.

    How to send us your prescription:
    • Fax: Call (713) 695-4939 for our fax line
    • Email: Have your doctor's office email us the Rx
    • In-store: Bring the paper prescription to our Houston showroom
    • Doctor-direct: Ask your doctor's office to fax/call us on your behalf

    Don't have a prescription yet? Talk to your doctor first — never use oxygen therapy without medical supervision. Incorrect flow rates can be dangerous. Call us at (713) 695-4939 and we can walk you through the prescription process.
    What's the difference between continuous flow and pulse dose oxygen concentrators?
    Two very different technologies:

    • Continuous flow (this 525DS): Delivers a constant, steady stream of oxygen through your cannula — whether you're inhaling or exhaling. Every breath gets the same oxygen concentration. Required for nighttime use, ventilators, CPAP/BiPAP with oxygen, and patients with high oxygen needs.

    • Pulse dose (portable units): Detects when you inhale and delivers a "puff" of oxygen only during inhalation. Uses less battery, so it's what makes portable oxygen concentrators (POCs) possible. But delivers less total oxygen per minute — not appropriate for all patients.

    Most patients start on continuous flow (like the 525DS) for home use, and add a pulse-dose portable unit for travel/errands. Your prescription will specify which type you need — don't substitute one for the other without talking to your doctor.
    Can I run the 525DS 24 hours a day, 7 days a week?
    Yes — the 525DS is specifically designed for continuous 24/7 operation. Drive Medical states it can run continuously at any flow setting, 365 days a year. That's exactly what a home oxygen concentrator is for. The rotary valve is tested to 10 million cycles (about 25,000 hours of continuous use, which is nearly 3 years of 24/7 operation), and the 3-year warranty covers you during that time. Turn-Down Technology also helps by reducing wear during lower-flow periods. Just remember to clean the intake filter weekly — that's the main maintenance for round-the-clock operation.
    What happens if the power goes out?
    The 525DS is not battery-powered — it plugs into a standard 120V outlet. If the power goes out, the concentrator stops producing oxygen and the power failure alarm sounds so you know immediately. This is why oxygen-dependent patients should have a backup plan:

    • Backup oxygen tank — a full "E" or "H" size compressed oxygen cylinder as emergency backup (we sell these)
    • Register with your utility — most electric utilities have programs for medical-equipment-dependent customers (priority restoration during outages, sometimes free backup generators)
    • Notify your local fire department — many will keep records of oxygen-dependent residents for emergency response
    • Portable oxygen concentrator (POC) — battery-powered units for extended outages

    Call (713) 695-4939 to discuss backup oxygen options for your situation.
    Do I need a humidifier bottle?
    Strongly recommended, especially if:

    • Your prescribed flow rate is above 2 LPM (dry oxygen at higher flows irritates nasal passages)
    • You experience nose dryness, nosebleeds, or crusting since starting oxygen
    • You live in a dry climate or use central heating in winter (both dry the air further)
    • You'll be on oxygen for extended daily use

    The 525DS has a recessed humidifier bottle nook specifically designed for a standard humidifier bottle. Only use distilled water in the humidifier — never tap water (tap water leaves mineral deposits that clog the bottle and can contaminate the oxygen stream). Change the water daily and clean the bottle weekly. Call us for humidifier bottle options and pricing.
    Is the 525DS covered by Medicare or insurance?
    Yes. Home oxygen therapy is a covered benefit under Medicare Part B with proper documentation — the 525DS carries HCPCS code E1390 (Oxygen concentrator, single delivery port, capable of delivering ≥85% oxygen). Medicare typically covers oxygen therapy as a monthly rental payment (about 36 months) with documented medical necessity, including:

    • Doctor's prescription specifying flow rate and hours per day
    • Blood oxygen test results (arterial blood gas or overnight pulse oximetry) documenting SpO2 ≤88% or PaO2 ≤55 mmHg
    • Diagnosis supporting long-term oxygen therapy (COPD, pulmonary fibrosis, CHF with hypoxemia, etc.)

    Coverage typically runs 80% (Medicare Part B), with the remaining 20% subject to your deductible and any secondary insurance. Medicaid and most private insurers also cover oxygen therapy.
