Block filter

The block filter is a larger intake filter designed for stationary oxygen concentrators such as the DeVilbiss Compact 525, Mars 10, and similar models. This type of filter captures large dust particles, dust mites, and other airborne contaminants before they reach the concentrator’s internal filtration system. Replacing the block filter regularly ensures optimal airflow and extends the device’s lifespan. The block filter is easy to replace yourself and requires no tools.
