More specifically, the placement and replacement process is adjusted in order to fit the qualifications of each user. The cleaning process is also quite simple, considering the fact that it requires only warm water and soap.

The filters must always be in place

The most important fact regarding this issue is that the filters must always be in their rightful place - at the intake end of the concentrator. Their function during operation is to provide clean input air, so their absence or mistaken placement can seriously harm the patient.

So, always make sure that both of the particle filters are in place. If the particles are drawn into the system, the action may even damage the equipment.

High priority alerts

Even though the particle filters seem like side section of the G3, they are definitely of high importance when it comes to the most important parts of the device. For instance, they have a significant influence over the work of the batteries, and may even be the cause for a high priority alert.

Battery HOT

More exactly, the batteries have a temperature limit which is connected to the production of oxygen. When the batteries reach their limit and the G3 does not produce oxygen, the patient receives a high priority alert.

When the user receives this alert, there are several things he/she needs to do. First of all, the device must be taken into a cooler place and immediately shut down. Yet, this does not solve the problem. In order to provide a solution, the user must check the functionality of the filters. As a G3 user, always make sure that the air intake and outlet vents have clear access and that the particle filters are clean.

System HOT

Another situation which requires checking of the filters is when the concentrator temperature is high and the oxygen production shuts down. The user needs to check if the air intake and outlet vents have clear access and if the particle filters are clean.

Cleaning the Inogen One G3 Gross Particle Filters

When it comes to cleaning any part of the Inogen One G3, the User Manual specifically points out the importance of cleaning agents types. More exactly, the user must not use other cleaning agents than those specified in it.
Like any other part of the G3, the particle filters don’t support the use of alcohol, isopropyl alcohol, ethylene chloride or petroleum based cleaners. The use of strongly scented detergents can seriously harm the equipment or reduce its lifetime.

In order to clean the filters, the user needs to remove them from the Inogen One G3. Both particle filters need to be cleaned with a mild liquid detergent, such as Dawn, and warm water. After the user of the G3 rinses the filters well, he/she needs to leave them to completely dry out before using them again.

The cleaning of the particle filters needs to occur on a weekly basis. More exactly, it is recommended by the manufacturer to clean the filters once in a few weeks in a normal environment, and at least once a week in dustier environments.
The cleaning of the filters provides the patient with accurate airflow, so the delay of this action may harm the functionality of the device.

Inogen One G3 Gross Particle Filters (Flow Setting 1-5) Replacement

Apart from regular cleaning of the gross particle filters, the user needs to replace the filters every 6 months. Even though this may seem like an insignificant action, this is considered as an issue of high importance. In order to provide a longer lifetime of the whole device, the user needs to take care of each individual part of it – particle filters included.
