There are many brands of oxygen concentrator on the market, and there are two main factors that affect its price: brand and model. Generally speaking, the home oxygen concentrator has 1L, 2L, 3L three specifications, there are also similar to the 5L of the larger oxygen concentrator, but the home then generally do not need too large capacity. Generally speaking, the price of one-liter machine is mostly between 1300-1500 yuan, if it is even lower, you need to consider the quality of the problem. The price of two-liter machine is mostly between 1500-1800 yuan, three-liter machine is generally more than 2000 yuan. There are also some oxygen absorbers on the market that cost less than 1,000 yuan, but after all, oxygen absorbers are medical devices, and it is still recommended to choose a better quality, brand-guaranteed oxygen absorber within the scope of economic conditions. In general, it is best to choose according to the user's situation is better, so that you can choose a good suitable home oxygen concentrator.
How to buy home oxygen machine
1, look at the oxygen generator oxygen mode
Oxygen generator oxygen mode there are three kinds of molecular sieve principle, polymer oxygen-rich membrane principle and chemical reaction oxygen principle. Only the molecular sieve oxygen concentrator is currently the only mature oxygen concentrator, is the only oxygen concentrator with international standards and national standards. Oxygen generator home which is good, in the purchase of oxygen generator to choose this molecular sieve type oxygen, it is directly from the air to extract oxygen, that is, fresh and natural, there is no high-pressure explosive and other dangers. And this kind of oxygen production method of oxygen concentration is pure, longer service life, is also the most popular.
2, see the size of the oxygen concentration
The size of the oxygen concentration is one of the important factors to determine the oxygen concentrator is good or bad, a good quality oxygen concentrator it should be able to stabilize the oxygen concentration at 90%.
3, look at the core components of the oxygen concentrator: molecular sieve and air compressor
Oxygen concentrator is through the air compressor, so that the air through the molecular sieve and obtain a high concentration of oxygen. A good oxygen generator will use imported high-quality molecular sieve, with strong adsorption performance, good oxygen effect, and long service life. In addition, the air compressor, need to use high efficiency, oil-free compressor, if the use of oil compressor will contaminate the oxygen, and harmful to the body, and a good oil-free compressor, requires strong performance, good heat dissipation performance, and running noise, and to ensure that the service life is long.
4, listen to the oxygen concentrator running noise
Because the oxygen concentrator running, need to use the air compressor, it will avoid the noise. A good home oxygen concentrator, the noise level is better than 45 decibels, otherwise, it may affect the rest of me and others, especially at night. In addition, some oxygen concentrators need to be cut off at the bottom of the oxygen concentrator before turning on the machine, which is used to fix the strapping of the oxygen concentrator, so as to avoid damaging the oxygen concentrator and generating a loud noise.
5, see whether there is a timer function
If there is a timer function, the oxygen concentrator working hours can be set freely by one key, and the machine will automatically shut off at the point of time, which is especially convenient for people with mobility problems or slow people to use, and relieve them from the trouble of getting up in the middle of the night to switch on and off the machine.
6, see whether the wet oxygen function
As the oxygen out of the machine is dry, the nasal cavity and nasal mucosa has a stimulating effect, therefore, if the oxygen concentrator has wet oxygen function, such as the configuration of the humidification bottle, you can be wet gas before the body inhalation, inhalation of oxygen is more comfortable. If the oxygen concentrator has this function, can not directly join the tap water need to add pure water, distilled water, cool white water.
7, see whether the oxygen concentrator has air filtration
If you inhale the unclean oxygen, it will bring harm to the fragile respiratory system, and even bring other diseases. A good oxygen concentrator will use a multi-stage deep gas filtration system to make the purified oxygen perfectly clean. Effectively avoid the inhalation of large particles of ash, airborne particles, pathogenic bacteria and other harmful substances.
8, look at the oxygen concentrator brand strength
The brand factor is an important factor in the selection of oxygen concentrator, which will relate to the oxygen concentrator after-sales service. In the purchase, it is best to choose a long history, the strength of the oxygen generator manufacturers, can effectively protect the future of the oxygen generator after-sales service, as well as the oxygen generator parts replacement. What brand of oxygen generator is good?MaiGoo editorial recommended oxygen generator top ten brands.
9, see whether the seller has the relevant brand authorization
If the purchase is a brand oxygen concentrator, in order to avoid the emergence of: the purchase of imitation brand, counterfeit, refurbished oxygen concentrator, and the impact of the use of the product and can not enjoy the product's after-sales service and so on, before the purchase, be sure to verify that the seller has to obtain the relevant authorization, it is best to go to the brand store, the official flagship store, etc., the credibility and security of the oxygen concentrator. The best way to protect your legitimate rights and interests is to buy from a store that has a high degree of credibility and protection, and to save the genuine shopping invoices and other proofs.
10, other requirements or features
In addition to the basic principles of the above purchase, but also according to their own actual needs, such as: with a remote control, with fault monitoring, SOS call, voice prompts, anion release, and even "rare" oxygen concentration real-time display of specific data and other functions. The oxygen concentrator is a home appliance.
