Because it is four times as thick as a 1-inch filter, it has a much greater surface area for catching household pollutants. These larger filters also typically come with higher MERV ratings and can capture more contaminants (e.g., pet dander, smoke, allergens, and bacteria) than a 1-inch filter.
UNDERSTANDING FILTER SIZES
Therefore, for example, a 16x25x4 filter is 16 inches long, 25 inches wide, and 4 inches thick. It's important to note that filters with different dimensions are not interchangeable due to variations in frame size and media area.

In most situations that is the case. Thicker air filters tend to last longer because they have more square footage to capture and hold air particles.
In conclusion, while the idea of stacking two filters might seem like a shortcut to better air quality, it can lead to more harm than good.
4-Inches Thick
This is still a very common size for air filters. Typically, your higher MERV filters are going to be around this thickness. This filter is recommended to be replaced once every 6 months.
This leads to a variety of issues for your HVAC system including system inefficiency, higher energy bills, inadequate air quality, and ultimately failure. If you haven't been swapping your air filters as frequently as you should, there's no time like the present to start practicing this crucial maintenance step.

MERV stands for minimum efficiency rating value. It's a nationally recognized measurement system that's used to rate every air filter. The rating is based on the filter's ability to catch particles of a specific size. The MERV rating range is 1-16, with 1 being the lowest and 16 being the highest.
