Deeper pleats result in a greater capture of airborne contaminants, which is how the Filtrete Deep Pleated 1550 replacement air filter excels over 1 or even 2 inch filters. Not that slimmer filter products are inferior. The same technology that makes a thicker filter so effective is used across Filtrete's entire lineup. Why a 4-inch filter is so successful at particle capture is the increased surface area. As moving air carrying pet dander, dust, or bacteria approaches the filter, due to the filter depth, the air spreads and more evenly distributes contaminants across the entire media. For homes with fewer air quality problems or those with mild allergies, a 4-inch filter may work for you because you won't need to change out the filter as often, though a 6 month replacement period is still recommended. For those with respiratory aliments, pets, heavy smokers, or anyone that loves to cook, a thicker filter with result if fewer pressure drops and fewer change-outs. It isn't uncommon for home with troubled air quality to go through slimmer filters on a monthly basis, which is where a 4-inch filter comes in handy.
