1. A multifunctional modular respirator comprising:
an elongate filter unit having a push-fit connector filter inlet, a thread-connector filter outlet, and a replaceable fluid filter for filtering pollutants within the fluid;
an elongate exhaust unit having a thread-connector exhaust inlet, an exhaust outlet, one or more one-way valves, a replaceable exhaust filter, and an air-sensing push-fit connector;
an interchangeable programmable air flow generator assembly; and
a mask assembly having a mask for covering the oral and nasal passage of a user, a threaded mask inlet at one end of the mask, a threaded mask outlet at an opposite end of the mask, wherein the mask inlet is releasably fastened to the filter outlet, and the mask outlet is releasably fastened to the exhaust inlet;
such that the filter unit is located on one side of a neck of the user and the exhaust unit is located on an opposite side of the neck of the user,
wherein the filter unit, the mask, and the exhaust unit jointly form a tightly sealed passage for the fluid to pass therethrough;
wherein the filter inlet is connected to a first end of the interchangeable programmable air flow generator assembly via a push-fit connector with a spring-loaded ring for connector release;
wherein the exhaust unit is connected to a second end of the interchangeable programmable air flow generator assembly via a push-fit connector with a spring-loaded ring for connector release;
wherein the multifunctional modular respirator is configured to operate as at least one of a powered air purifying respirator (PAPR), an air purifying respirator (APR), a programmable inhalation resistance training respirator;
wherein the interchangeable programmable air flow generator assembly is programmed to maintain a positive pressure and positive flow required when the multifunctional modular respirator is operating as the PAPR, and wherein the interchangeable programmable air flow generator is programmed to maintain an adjustable negative pressure and reverse flow when the multifunctional modular respirator is operating as the programmable inhalation resistance training respirator;
wherein a single string strap assembly is configured to fasten the mask assembly to a head and the neck of the user;
wherein the mask assembly comprises a cooperating bridge linking a mask body with each end of the mask; wherein the bridge forms a loop to allow a single string of the single string strap assembly to pass through;
wherein the single string strap assembly comprises: the single string, a pad, and a latch;
wherein the single string forms a closed loop with one end of the closed loop located at the pad adapted to be placed on a back of the head of the user; and a second end being located at the back of the neck of the user; and
wherein two opposite ends of the single string are pulled through the latch to form the closed loop.
