As a result, it is important to change your 16x25x4 furnace filters at least every 3 months. You should also be aware of what types of 16x25x4 furnace filters are available and how often you need to change them based on their efficiency level.
The standard recommendation is to change your furnace filter every 1-3 months, depending on the type of filter you have and the conditions within your home. For instance, if you have pets or if someone in your household has allergies, you may need to change the filter more frequently to ensure optimal air quality.
For 1- to 2-inch filters, replace them every 1 to 3 months. For 3- to 4-inch filters, replace them every 6 to 9 months. For 5- to 6-inch filters, replace them every 9 to 12 months.
Larger area for catching debris: 5-inch air filters offer a thick surface area of accordion-shaped material to catch all the dirt you want to keep away from your family. For cleaner air, the thicker filter provides less debris slipping through the cracks.

What Is the Most Common Size of Air Filter for a House? The most common size air filter for a house is usually 20 x 20 x 1, but this can vary depending on the specific HVAC system installed.
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.
If you keep experiencing this situation in your home, we recommend you start with a whole-house duct cleaning to eliminate most of the excess dust and dirt in your home's HVAC system. Then, consult with one of our expert heating and cooling technicians to find the optimal filter for your HVAC system.
Our standard recommendation is as follows: For 1- to 2- inch filters, replace them every 1 to 3 months. For 3- to 4- inch filters, replace them every 6 to 9 months. For 5- to 6- inch filters, replace them every 9 to 12 months.
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.
Pleated filters are more efficient and will last longer than fibreglass filters, as polyester is much denser than fibreglass. The MERV rating of a disposable pleated furnace filter will range from 7 to 9.
Going down in thickness by an inch shouldn't be a big deal - for example, you should be able to use a 4-inch filter instead of a 5-inch filter. If you are considering a thicker air filter in order to improve air quality it may be better to focus on the MERV rating.
Expensive air filters are made from higher-quality materials, like fiberglass, that can last for up to 12 months. This not only saves you money, but it's also more convenient since you won't have to remember to replace your air filters as often.
Air filters that are overdue for a change are a common cause of HVAC system failure. Over time, dirt builds up in the heating and AC filters, causing components such as the motor to go into overdrive, which may eventually overheat your unit.
That's why Lowe's offers a wide selection of house air filters to suit your needs. We even carry air purifier filters for your air purifier. Whether you call it a furnace filter, heater filter or A/C filter, the job is the same: to filter the air you breathe.
Filters with a MERV rating of 8-13 are usually higher-end filters for home use or high-quality commercial filters. These filters are typically the right choice for use in homes and many businesses.
A buildup of debris in your vents can restrict proper airflow, leading to incorrect combustion of your furnace leading to brown or black soot and debris accumulating on your filter. You may also notice that the heat from your vents isn't as warm as it should be or blowing out as much air.
You can run the furnace without installing a filter, but only temporarily (such as overnight, awaiting a new filter). If you let it run very long without filtration, contaminants will build up.
When you purchase a 4″ filter over a 1″ filter, you're likely to pay more. That's because 4″ filters last longer and they also provide better air quality for your home. So, even though they cost more than a 1″ filter, theoretically the costs can level out since they will last longer than a cheaper filter.
The arrow on your air filter should point towards the blower in your HVAC unit. This ensures that the filter catches particles and debris before they enter the system, protecting the internal components from damage.
Standard air filters have pre-defined nominal sizes for compatibility with most HVAC systems. Custom-made filters fit non-standard dimensions. The Nominal filter size for a custom filter may still round to convenient measurements, but its actual size matches the dimensions of the HVAC system or filter slot.
