13. A method comprising:
disposing a downhole tool into a wellbore, the downhole tool comprising:
a body,
an intake port provided along the body,
a filtration device contained within the body and in fluid communication with the intake port, the filtration device comprising:
a first particulate removing filter configured to filter fluid below a predetermined concentration;
an entry sensor configured to facilitate identification of a first fluid property; and
an exit sensor configured to facilitate identification of a second fluid property when the first particulate removing filter filters the fluid below the predetermined concentration;
a bypass mechanism that changes a route of the fluid when a pressure difference associated with the first particle removing filter reaches a predetermined value, the predetermined value corresponding to clogging of the first particle removing filter, wherein the bypass mechanism changes the route to direct the fluid:
to a second particle removing filter;
in a reverse direction; or
around the first particle removing filter; and
an optical sensor for monitoring an optical density of the fluid routed in the reverse direction when the first filter is cleaned; and
an exit port in fluid communication with the filtration device for ejecting the fluid to an exterior of the body, passing the fluid through the filtration device, and ejecting the fluid from the exit port.
