Which PSA oxygen generator is better? Ten principles to guide your purchase

  What kind ofPSAOxygen Concentratoris better? Ten principles to help you buy a satisfactory oxygen concentrator Brand! The price of a household oxygen concentrator is generally1000yuan and above, which is a considerable expense for many families. Currently, there are manyPSAoxygen concentrator Brands on the market, with varying quality. If you want a product that is worth the money, you need to know the following10principles for choosing a homePSAoxygen concentrator.

　　Principle 1: Oxygen purity not less than90%。According to the Chinese Pharmacopoeia, the purity of medical oxygen must not be less than99.5%，the purity of medical molecular sieve oxygen concentrators must not be less than90%。Oxygen concentration that is too low is useless for oxygen therapy. The oxygen purity of oxygen membrane oxygen concentrators is only30%approximately, and should not be considered.

　　Principle 2: Has an unchanging cumulative timing function. The cumulative timing function reflects the product quality and is an important basis for consumers to seek repairs when the product malfunctions. Generally, it is required thatPSAthe service life of the oxygen concentrator reaches10000hours or more.

　　Principle 3: Operating noise is less than45decibels. Continuous operation noise is less than45decibels, to avoid affecting the sleep and rest of the oxygen user and their family members. This principle is particularly important at night.

　　Principle 4:PSAOxygen ConcentratorThe compressor displacement is large enough, and the compressor displacement should reach3.8 ~ 4.2cubic meters/per hour. If the exhaust volume is too small, the oxygen generator will wear out quickly, causing the oxygen concentration to drop rapidly.

　　Principle 5: Consider importing molecular sieves from abroad, which arePSAcore components of the oxygen concentrator and determine the performance and quality of the oxygen concentrator. Objectively speaking, foreign molecular sieve technology is superior to domestic technology.

　　Principle 6: Oxygen concentrators with monitoring and warning functions for oxygen concentration. When the oxygen concentration is lower than the safe value, a warning can be given to ensure the safety of the patient's oxygen inhalation.PSAPrinciple 7: Pass

　　ISOInternational,CEEuropean quality system certificationoxygen concentrator. Domestic production standards are not strict enough, and oxygen concentrators that have passed double foreign certifications have more guaranteed product quality.PSAPrinciple

Eight:Prioritizeten oxygen concentrator Brands. It recommends several reliable and cost-effective Brands and Models, making your purchase more reassuring.PSANine

Eight:：Good pre-sales and after-sales service Many people are using homeoxygen concentrators for the first time. Manufacturers or sellers should be able to answer consumers' basic questions about oxygen therapy. Unlike general household appliances, oxygen concentrators lack repair stations, so it is required that in case of product failure, it should be easy to exchange, return, or repair.PSATen

　　Eight:：Meet your actual needs. Expensive is not necessarily good, and cheap is not necessarily bad. Purchase products according to your actual needs. If your economy is not sufficient, consider the cost-effectiveness and choose domestic Brands.：满足你的实际需求。贵的不一定好，便宜的不一定坏。，议根据您的实际需求购买产品。如果经济不充裕，考虑性价比，可以选择国产品牌的PSAOxygen Concentrator。
