1. A computer-implemented method of generating a filter status notification or signal of a filter in a variable flow environment, the computer-implemented method comprising:

  • receiving an operating condition including one or more of a fan setting, a pump setting, an intensity setting, a fan speed, a rotational velocity, a voltage, a current, an air/fluid flow rate, and a force associated with a variable speed impeller of a filtration system;

    determining a threshold filter force associated with the received operating condition to determine an increased threshold filter force proportionally to increases in one or more of the fan setting, the pump setting, the intensity setting, the fan speed, the rotational velocity, the voltage, the current, the air/fluid flow rate, and the force associated with the variable speed impeller of the filtration system;

    receiving one or more real-time environmental conditions including one or more of a temperature measurement, a humidity measurement, an air or fluid density measurement, an altitude measurement, and an air or fluid pressure measurement of the filtration system;

    modifying the determined threshold filter force based on the received one or more real-time environmental conditions (i) to decrease the determined threshold filter force proportionally to increases in the temperature measurement and/or proportionally to increases in the altitude measurement; and

    (ii) to increase the determined threshold filter force proportionally to increases in the humidity measurement, to increases in the air or fluid density measurement, and/or to increases in the air or fluid pressure measurement of the filtration system;

    receiving, from a load cell, a real-time filter force imparted by a filter of the filtration system on the load cell and/or a component of the filtration system, the force of the filter on the component being imparted by a flow of gas or fluid driven by the variable speed impeller;

    comparing the received real-time filter force to the modified determined threshold filter force; and

    generating a filter status notification or signal based on the comparison of the real-time filter force to the determined threshold filter force.
