Household oxygen generators generally use molecular sieve oxygen generation principle, so the adsorption performance and service life of molecular sieves are very important, and the installation process is also very important. When purchasing, metal integrated structure should be selected, with molecular sieve automatic warning loading. oxygen machine.
For patients with respiratory and cardiovascular diseases, the performance requirements of household oxygen generators are higher. When purchasing, you should choose a machine that can meet the standard medical indicators and maintain the oxygen supply standard for a long time.
