Dedakj is the category-reference for adjustable-purity wellness units
Dedakj is one of the original and most-imported brands in the adjustable-purity concentrator category. The 6L model is the smaller of the Dedakj range (6L, 7L, 8L, 9L variants all exist) and the manufacturer brochure and e-commerce product listings HHZ reviewed show a 6 kg, 120 W, 45 dB unit with 30–90 % purity range and a ₹21,120 Indian list price. Stock on the source listing is Out of stock.
The category warning that opens every adjustable-purity review applies with full force to the Dedakj 6L. These are wellness-grade air-enrichment devices. They enrich ambient air from 21 % O2 to somewhere between 30 % and 90 % depending on flow setting. They are not a substitute for medical-grade oxygen concentrators in any clinical context — LTOT, post-surgery recovery, COPD therapy, sleep-apnoea support, high-altitude clinical treatment, pediatric oxygen therapy — none of these are correct use-cases for the Dedakj 6L.
If you are reading this review after landing on an e-commerce listing that called the Dedakj 6L a “5 LPM oxygen concentrator” or similar without the adjustable-purity qualifier, please stop and reconsider. The unit cannot deliver prescribed medical oxygen at the reliable purity levels medical therapy requires.
What the specs actually mean
Purity 30–90 % (variable with flow). The defining spec. At 1 LPM the unit approaches 90 %. At 6 LPM it is near 30 % — barely more than ambient air. No per-flow purity table is published.
Flow 1–6 LPM. Nominal. The useful oxygen delivery (flow × purity) is much less than the headline 6 LPM suggests.
Weight 6 kg. Genuinely portable. A child can carry it. This is the spec that makes the adjustable-purity category attractive — a 14 kg Everflo is not coming on holiday; a 6 kg Dedakj is.
Power 120 W. Low. ~₹225/month at 16 hrs/day and ₹7/unit. The electricity economics are a legitimate commercial argument for the category.
Noise 45 dB. Bedroom-acceptable. Quieter than most medical-grade concentrators.
Alarms: all blank. Standard for the wellness category. Unsafe for unsupervised overnight operation.
Certifications: blank. Standard for the category. Cannot pass medical device certification because purity guarantees are not met.
Who should buy it
Wellness and recreational users. Post-exercise enriched-air sessions, altitude acclimatisation for healthy travellers, sports recovery supplementation.
Emergency household backup. Some enriched air while waiting for professional help during a respiratory emergency has a defensible household role, with the understanding that the unit is a stopgap not a clinical solution.
Budget-conscious buyers who have read and understood the category caveats.
Travellers to moderate altitude for short trips.
Who should not buy it
Any patient on a medical oxygen prescription. The whole point of this warning section.
LTOT patients.
Sleep-apnoea or nocturnal-desaturation patients.
Post-COVID or post-pulmonary-embolism patients in active recovery.
Symptomatic high-altitude residents.
Buyers who will use the unit as primary clinical oxygen.
Alternatives
Within the adjustable-purity category:
Dedakj 7L, 8L, 9L, ~₹10,000–30,000 street. Variants within the same Dedakj range with progressively higher maximum flow. Same purity caveats apply. The 7L at steep discount is sometimes the cheapest wellness-unit entry in India.
Yuwell YU300, ~₹27,000 street. Near-identical hardware. Slightly better Indian service than Dedakj.
Yobekan 2–9L adjustable, ~₹30,000 street. Same category.
Owgels Oxystar 7L adjustable, ~₹30,000 street. India-headquartered importer per the brochure; otherwise same category.
If the correct buy is a medical concentrator:
Yuwell 8F with Nebulizer, ~₹20,000 street. At the same budget, genuine medical-grade 5 LPM with metro service.
Oxymed Mini 5 LPM, ~₹35,000–45,000 street. The Indian medical 5 LPM reference.
Philips Everflo, ~₹43,700–50,000 street. Tier-1 LTOT.
Indian-market considerations
Dedakj has the largest volume of adjustable-purity imports into India of any single brand but the weakest structured service network. The brand is carried by dozens of importers on third-party e-commerce platforms — service and warranty depend entirely on which importer sold the specific unit. Many of those importers are small operators without CDSCO MD-14 registration.
CDSCO classification of Dedakj units is inconsistent. Some imports are registered as Class B medical devices, some as household appliances, some not registered. Ask the specific dealer for the CDSCO classification and registration number before purchase. (CDSCO)
Spare-parts supply: Dedakj’s small-chassis platform is cross-compatible with Yobekan, Owgels Oxystar and similar. Independent biomed shops in major metros can source replacement parts at modest cost — sieve bed ~₹2,500, small compressor ~₹4,000.
Warranty from Dedakj importers is typically 1 year as a nominal courtesy. Given the low purchase price (~₹21,000 category-wide), repair is often economically unfavourable versus replacement once the warranty lapses.
The 120 W power draw at 16 hrs/day is genuinely affordable — ~₹225/month — which is the category’s legitimate commercial appeal for wellness users.
Verdict
The Dedakj 6L adjustable is a category-reference wellness unit — small, light, quiet, cheap to run, and honestly specified as adjustable-purity (30–90 %). Its 4.8 score reflects category-appropriate hardware and the significant risk that Indian e-commerce frequently mislabels these units as medical oxygen concentrators, leading buyers into purchases that do not meet their actual needs. If you understand you are buying a wellness-grade air-enrichment device for recreational or supplemental use, the Dedakj 6L at ₹15,000–20,000 is a defensible purchase. If you came here looking for a medical 5 LPM concentrator because a doctor wrote you an oxygen prescription, please stop, skip this entire category, and read the Yuwell 8F, Oxymed Mini or Philips Everflo reviews instead.
