Abstract
A downhole filter with a filter housing having a top filter and a bottom filter disposed therein. The filter housing can be in fluid communication with each filter. Each filter can be in fluid communication with a burst disk housing having a burst disk module and a burst disk. Each burst disk housing can be in fluid communication with the filter housing. Fluid can flow through the filter housing and through the filter. When a filter is clogged, the fluid can burst a burst disk, thereby bypassing the filter. The downhole filter can include a middle sub in fluid communication with the top filter and a second portion of the filter housing. The middle sub can threadably engage a bottom burst disk housing.
