Can you put 2 air filters together?
Can You Stack Air Filters? Do not stack multiple smaller air filters on top of one another to fit them into a larger air handler. Installing multiple 1” air filters in a 2” slot, for example, can cause costly damage to your AC unit, as residential furnaces are not equipped to handle this level of airflow restriction.
Can you layer air filters?
In some cases, your intake vents or air handler vents have a filter depth greater than an inch. Because 1 inch air filters are the most common, some homeowners may think it’s okay to layer 1 inch air filters to fit a 2-, 3-, or 4-inch air filter slot. It’s not recommended to do this.
Do higher MERV filters restrict airflow?
Wrong. While the highest MERV ratings are the most effective for air quality, they can harm your HVAC system. A higher MERV rating means a higher resistance, which means less airflow.
Does width of air filter matter?
Most air filters are 1 inch thick, but some systems can accommodate filters 2 to 5 inches thick. In our tests, we found that the thicker the filter, the better it works and the longer the replacement intervals. That means it’s better for you and for your heating, ventilating, and air conditioning (HVAC) system.
Are 2-inch filters better than 1?
Well, the thicker the filter the less restrictive it is. This contributes to a better flow of purified air. This means that 2-inch furnace filters allow a better flow of air than 1-inch filters.
Does every return vent need a filter?
In general, it is recommended to have an air filter in every return vent (as long as you choose the one of the right size and thickness). The filters will improve the air quality in your house and will protect the HVAC equipment from dust, pollen, pet dander, and hair.
Can an AC filter be too thick?
If you get a filter with pleats that are too thick, your filter could get dirty quickly. Thus, making your AC unit work harder than it needs to. A good benchmark to follow when considering MERV ratings is that if it’s more than 13, the pleats are most likely too thick for your filter.
Can an air filter be too big?
If you purchase a filter that’s too large, it won’t slide into the slot correctly. If the filter is too small, it won’t cover the entire space and may allow dust and dirt to flow past.
Are pleated filters bad for AC?
Pleated filters are bad for your system because they block too much air, forcing the HVAC motor to work harder to pull in the air it needs and burning it out faster.

Can I use a 2 inch filter instead of 1 inch?
Higher MERV ratings work best when the filter is 4” thick or thicker because they trap extremely small particles, which means contaminants will build up quickly on the screen. If your system only fits a 1-inch or 2-inch filter, a high MERV rating could be detrimental.
Do vent filters block air flow?
The biggest drawback of vent filters is restricted airflow. Filters slow the passage of air. As particles build up on them, the amount of obstruction increases. This can cause your system to work harder, using up more power and potentially overheating components.
Why does my central air have two filters?
A lot of central air units have at least two filters, though you can find systems that have only one. The reason why there are a couple of filters is because not only the air that is traveling into the air handler needs to be filtered, but also the air passing through the return vents.
