The first and foremost difference between 1-inch and 2-inch filters is their lifespan. Generally, the thicker the filter, the better it performs and the longer the replacement intervals. This means it's better for you and your heating, ventilation and air conditioning (HVAC) system. The Department of Energy states that replacing a dirty filter with a clean one can reduce HVAC energy consumption by 5 to 10 percent, resulting in significant monthly savings.
Most filters clearly recommend how often they should be replaced, usually between one and six months. Using a permanent marker, draw the direction of the air flow outside the oven so that you always know the correct way to install the filter. A good reference point to follow when considering MERV ratings is that if it is higher than 13, the folds are most likely too thick for the filter. Like length and width, thickness is an important part of sizing oven filters and obtaining the right fit to optimize performance.
This creates charged particles that attract other particles in the air for better filtration when electrostatic filters are used. This is usually as simple as looking at the current filter and, assuming it fits correctly, finding the air filter sizes as well as the dimensions on the label. Improve indoor air quality Replacing your standard one-inch air filter with a 5-inch pleated filter can improve the air quality inside your home. Reducing the thickness by one inch shouldn't be a big problem; for example, you should be able to use a 4-inch filter instead of a 5-inch filter.
Thicker air filters tend to last longer because they have more square feet to capture and retain air particles. If your current furnace only allows furnace filter sizes with a depth of one inch, HVAC contractors can modify the furnace to fit larger sizes.
