on the other hand, Are 5 inch filters better than 1 inch?
Enhance Indoor Air Quality
Replacing your standard one-inch air filter with a pleated 5-inch filter can result in better air quality inside your home. That’s because bigger air filters feature higher MERV ratings, leading to better filtration of pollutants and allergens.
also, Should I use a 1 or 2 air filter? The general best practice is to use the thickest air filter you can for maximum efficiency. … If your system only fits a 1-inch or 2-inch filter, a high MERV rating could be detrimental. A 1-inch filter with less surface space will get clogged fairly quickly and need to be replaced much sooner than a thicker filter.

Are air filter sizes exact?
The actual dimension of an air filter is its exact size. Generally, actual dimensions are smaller numbers than nominal measurements. A 16 x 25 x 1 nominal measurement may have the actual dimensions of 15 1/2 x 24 1/2 x 3/4.
How long does a 5 inch filter last?

Can you stack air filters?
Bottom Line: Putting two air filters on a central air system will only have the net effect of producing a higher utility bill and reducing the lifespan of your central air unit. In short, the use of two air filters is just a BAD idea!
Is the furnace filter the same as the AC filter?
However, if you have separate heating and cooling systems, your furnace and air conditioner may require different filters. In terms of function, there is no difference between the two as they’re both designed to serve the same purpose: protect your system from harmful air particles and improve air quality.
Can you use 2 air filters?
Bottom Line: Putting two air filters on a central air system will only have the net effect of producing a higher utility bill and reducing the lifespan of your central air unit. In short, the use of two air filters is just a BAD idea!
Does depth of air filter matter?
If improving air quality is a priority for you, depth of the filter doesn’t matter so much as MERV. The higher the MERV rating, the smaller the contaminants a filter can trap—which also means it will clog faster.
Is a larger air filter better?
Smaller filters will clog faster than larger ones, given the same carb cfm. As filters load up, the pressure differential across them increases, which decreases the engine’s ability to draw air through them. The bigger the filter element, the better.
How often should you change a 4 inch air filter?
When to Change an Air Filter
Every three months for 1-inch to 2-inch filters. Every three months for pleated media filters. Every six months for 4-inch filters.

What happens if air filter is too small?
Consequences of Using an Air Filter That is Too Small:
The filter can be sucked into the ventilation if it is much smaller than it should be. … Dust, allergens and pollutants will not be filtered from your indoor air, as the air is bypassing the filter and entering into the ventilation and is returned back.
Why are air filters different sizes?
The die-cuts (filter frames) are manufactured in bulk and purchased as a raw material for making air filters and determine the exact size of the air filters. The exact size is always slightly smaller than the nominal size to allow the filter to properly fit in the slot or housing.
What do air filter sizes mean?
The actual size is the exact dimensions with no rounding; whereas, the nominal size is the rounded dimensions of the filter. This means that on 1″ and 2″ air filters, the nominal size does not include the undercut, and the actual size does include the undercut.
