Founded in 2005, Turtle specializes in household respiratory medical equipment, holds a number of national patents, has nearly 100 service centers across the country, and has relatively convenient after-sales service, and has also been rated as "China's Top Ten Satisfactory Brands of Household Medical Devices". Its desktop oxygen concentrators have a complete range of products and reliable quality, and have been exported to more than 50 countries and regions.
 
The Turtle's 8L ultra-large flow machine V8-NS not only ensures sufficient oxygen output and oxygen concentration, but also has an optional atomization function, which is suitable for household use. The 5L medical oxygen generator V5-NS is easy to operate, but it weighs 50% more than the Philips Everflo of the same specification. Its price is 4580 yuan, which is more cost-effective. Considering the users who live above 3000m above sea level, the turtle has launched the V5-NS plateau version, with the same configuration, and it can also run stably at an altitude of 4800m, priced at 5380 yuan.
 
The turtle household oxygen concentrator advertises that a knob can complete all operations, but its operation logic is complex, not suitable for the elderly who are not used to seeing the LED screen, and the product does not support remote control, in fact, the operability is worse, and you need to pay attention to it when buying. The two products are similar to Yuyue products of the same specification in terms of mute and power, but the price of the 3L VH3-D is 2880 yuan, and the price of the 2L DMH2 is 2280 yuan, which is slightly more expensive than the Yuyue. Both have an atomized version and are only 100 yuan more expensive than the standard version, which is more cost-effective than buying another atomization device.
