Weaker filters do not guarantee air purification from the most harmful micropollen such as 2.5PM\u003c\/p\u003e\u003cp\u003eThe paper is characterized by high filtering efficiency and low air resistance (pressure drop \u0026lt; 10 Pa), therefore it is also suitable for installations that do not require forced air flow (fan).\u003c\/p\u003e\u003ch2\u003ePictured below is a contaminated filter after 2 weeks of operation. The filter was placed at the air inlet to the apartment.\u003c\/h2\u003e\u003ch2\u003eUsing filr paper, you can turn your air conditioning into an air purifier at a low cost, as in the photo below\u003c\/h2\u003e\u003cp\u003eThe offered HEPA filter consists of tightly arranged polypropylene fibers with a very small diameter (about 0.5μm to 2μm). Unlike membrane filters, the filter does not act as a sieve that filters particles larger than the pore diameter of the membrane, but its action consists in entrapment of particles by filter fibers (particles adhere to fibers).\u003c\/p\u003e\u003cp\u003eThe filtering process consists of several different mechanisms:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eInterception\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThe particles in the air stream penetrating the filter are greater than the distances between the filter fibers or greater than the pores in the filter membrane. The filter in this case acts as a sieve, trapping sufficiently large particles. The capture efficiency is the higher the larger the captured molecule. Capture efficiency decreases significantly for molecules smaller than 0.3μm.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eClash\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eParticles in the air stream penetrating through the filter interfere with densely arranged filter fibers or filter membrane and settle in the filter.

This phenomenon is effective for small molecules.
