Nidek Nuvo Lite Mark 5 Compact Oxygen Concentrator (Model 525): A Complete Guide
An ultra-compact, ultra-quiet stationary concentrator built for low-flow continuous therapy — 12 flow settings from 0.125 to 5.0 LPM, rapid RPSA startup, and just 32 pounds of net weight.
Not every continuous-flow oxygen prescription calls for high output — many patients, including pediatric cases, need precise low-flow settings alongside quiet, energy-efficient operation. The Nidek Nuvo Lite Mark 5 (Model 525) is built specifically for that low-flow range.
Delivering continuous-flow oxygen across 12 settings from 0.125 to 5.0 LPM at 90% (+6.5%/-3.0%) purity, the Nuvo Lite uses Nidek’s proprietary Rapid Pressure Swing Absorption (RPSA) technology to reach full therapeutic concentration in under 3 minutes, all while operating at an ultra-quiet ~40 dBA.
Engineered by Nidek Medical Products, Inc.

As a Class II FDA-regulated medical device, it is available strictly by prescription.

Who Is the Nuvo Lite Mark 5 Typically Prescribed For?
The Nuvo Lite is well suited to patients whose prescribed flow rate falls in the low-to-standard range — including pediatric and adult continuous oxygen protocols requiring precise low-flow settings down to 0.125 LPM. Its ultra-quiet operation and compact 32 lb chassis also make it a strong fit for home health placements and overnight care where acoustic disruption and space are concerns. As with any oxygen device, the appropriate flow rate should be determined by your physician based on your specific prescription.
Adding the Nuvo Lite Mark 5 to the EnhDme-Pro catalog gives physicians and facilities a precise, ultra-quiet low-flow option to complement our high-flow Nidek Nuvo 8 and Nuvo 10 listings.
