The air filter in your heating and cooling system performs the extremely important job of eliminating allergen particles to keep your system clean and making your indoor environment healthy. When the filter performs its job, it gets clogged after a certain time period as more and more particles are loaded on it. When this happens, you are more likely to suffer from respiratory illness.

Important Note: The size mentioned on the box of the filter is slightly greater than the actual size of the filter, normally referred to as a nominal size. If the nominal size of the filter is 10x20x2, then the actual size is 9.5X19.5X1.75, so measure your filter dimensions accordingly to find the right size air filter.
