After the acquisition of CAIRE's business, the charter group entered the field of respiratory oxygen therapy equipment, and then successively acquired SeQual and AirSep, which are collectively known as "Asia" in the Chinese market. Therefore, Asia has a full range of oxygen products, and it has reached the top level in each small category.
 
Many patients receive more than 15 hours of oxygen therapy per day, which requires the oxygen concentrator to work continuously and stably. The sub-adaptive oxygen concentrator can ensure 30,000 hours of operation, and the stability guarantee time is the longest among all oxygen concentrator brands on the market. And the special air filter technology is used to greatly simplify the machine maintenance process.
 
The 10L ultra-large flow model of the Newlife series, the Newlife Intensity, is mainly used in hospitals, and the 5L flow model Newlife Elite and visionaire 5 can meet the needs of most users. visionaire 5 is not inferior to Newlife Elite in terms of performance, weight, and quietness, and the price of 5980 yuan is obviously more worth buying than the Newlife Elite of 8380 yuan.
 
The portable oxygen concentrators have been approved by the FAA and can be used on the plane. The 0.8kg Focus is the lightest of the competition, but it doesn't perform as well as the eQuinox and Eclipse. Both the eQuinox and Eclipse weigh more than 6kg, and although the trolley-style design can solve some of the problems, it is still not convenient for users who do not have an elevator at home or often cross the overpass.
 
Balancing weight and performance, the Freestyle series is undoubtedly the most recommended portable oxygen concentrator for AS, weighing no more than 3 kg, and the operator panel is very simple and easy to use. The short battery life is a fly in the ointment, and it needs to be equipped with a spare battery, but the price of the product itself is more than 20,000 yuan plus a spare battery of 6,000 yuan, which is high in similar products.
