õhufilterit

An õhufilter, or air filter, is a device designed to remove contaminants from the air that passes through it. These filters are commonly found in a wide range of applications, including HVAC systems for buildings, internal combustion engines in vehicles, and various industrial machinery. The primary function of an õhufilter is to protect downstream components from damage caused by dust, pollen, soot, and other airborne particles. In the case of engines, clean air is crucial for efficient combustion and to prevent wear on internal parts like cylinders and pistons. For HVAC systems, air filters improve indoor air quality by reducing allergens and pollutants, contributing to a healthier living or working environment.

Õhufiltrid are typically constructed from porous materials such as paper, foam, or synthetic fibers. The type of material and its weave density determine the filter's efficiency in capturing particles of different sizes. As air passes through the filter, larger particles are trapped by the filter media, while cleaner air continues through. Over time, these trapped particles accumulate, causing the filter to become clogged. A clogged õhufilter can restrict airflow, reducing the efficiency of the system it serves and potentially leading to increased energy consumption or component strain. Therefore, regular inspection and replacement of õhufiltrid are essential maintenance procedures for most systems.
