Your Oxygen Generator Oxygen Concentration is Low?

Oxygen generator oxygen purity is low? It may be related to filter cotton


Normal people can intercept them outside the body through nasal filtration, trachea and bronchial system, alveolar giant cells and other filtering mechanisms. But people with respiratory and lung diseases can't stop it. So how should they ensure the cleanliness and health of breathing?
At this time, the filter/filter cotton of the oxygen generator plays the role of air filtration. If the oxygen concentration of your oxygen generator becomes low or makes abnormal noise, it may also be related to the filter/filter cotton.

The importance of filters/filter cotton affects the life of the machine and respiratory health


The filters/filter cotton of the oxygen generator are generally divided into primary filters and secondary filter cotton: the primary filter looks like a sponge, and its main function is to filter dust and other impurities in the air to ensure the cleanliness of the air entering the oxygen generator.

Oxygen concentrator primary filter cotton

> Relying on electrostatic adsorption, it effectively prevents finer dust from entering the machine, effectively protecting internal parts such as turbines and solenoid valves;
> Protecting molecular sieves from pollution;
> Effectively extending the life of the oxygen concentrator;
> At the same time, it blocks harmful substances such as fine particles in the air from entering the oxygen supply system to ensure the cleanliness of the oxygen supply.

DEDAKJ RESPIREASY oxygen concentrator filter cotton/filter replacement suggestions

The filter/cotton is the first barrier of the oxygen concentrator, which can intercept most harmful substances and pollutants. If it is not cleaned or replaced for a long time, dust and other pollutants in the air will adhere to the filter cotton, causing blockage and breeding bacteria, affecting the oxygen concentration and cleanliness, and even causing the oxygen concentrator to not produce oxygen, causing harm to both the human body and the machine

Replacement suggestions for the primary filter

> It is generally recommended to clean and replace the primary filter every 2 weeks. If the filter is damaged, yellowed, dirty, or blackened, it needs to be replaced in time.
Replacement suggestions for the secondary filter cotton
> The secondary filter cotton is a disposable consumable and cannot be reused. Its service life mainly depends on the cleanliness of the ambient air. If the use environment is relatively clean, the secondary filter cotton will take about 800-1000 hours to become obviously black; if the ambient air is highly polluted, such as a lot of wind and sand or frequent polluted weather in industrial cities, it may become obviously black after about 200 hours of use.

Since the oxygen concentrator is related to the health and life safety of the user, and the secondary filter cotton is a very important air filtration barrier, out of concern for the health of the user, DEDAKJ RESPIREASY recommends that you check or replace it after about 200-300 hours of use.

RESPIREASY oxygen concentrators are equipped with a 10-level air filtration system. In addition to the primary filter and secondary filter cotton, there are also molecular sieve filtration, gas tank filtration, bacterial filter, etc., which fully guarantee the cleanliness of oxygen, so that everyone can enjoy oxygen therapy!
