Understanding the Different Types of 16x25x4 Air Filters

When it comes to choosing the right 16x25x4 air filter for your HVAC system, there are several different types available on the market. Each type has its unique features and benefits, making it important to understand the differences between them to make an informed decision. Here are the most common types of 16x25x4 air filters:

1. Fiberglass Air Filters: These are the most basic and economical air filters available. They are made of layered fiberglass and capture large particles such as dust and dirt. However, they do not trap small particles, allergens or airborne pollutants, so they may not be the best choice for people with respiratory issues.

2. Pleated Air Filters: These filters have a higher MERV (Minimum Efficiency Reporting Value) rating than fiberglass filters, which means they capture smaller particles, including allergens and mold spores. Pleated filters are typically made of polyester or cotton and have a larger surface area, allowing them to capture more particles before needing to be replaced.

3. Electrostatic Air Filters: These filters use static electricity to capture particles, and they are highly efficient at trapping small particles such as pollen, pet dander, and bacteria. Because of their efficiency, electrostatic filters are often recommended for households with family members who have respiratory issues.

4. HEPA Air Filters: HEPA (High-Efficiency Particulate Air) filters are the gold standard when it comes to air filtration. They are capable of capturing particles as small as 0.3 microns in size, including viruses and bacteria. However, they are not compatible with all HVAC systems and can be expensive to replace.

By understanding the different types of 16x25x4 air filters, you can choose the right filter for your home's needs. Consider your family's respiratory issues, as well as your budget, when making your decision.

3. Cost: While cost should not be the only factor in your decision, it is important to consider the long-term costs of air filter replacement. Cheaper air filters may need to be replaced more frequently, which can add up over time. However, more expensive air filters may not necessarily be the best option either. Look for a balance between price and performance to ensure that you are getting the most for your money.

4. Compatibility: When purchasing 16x25x4 air filters, be sure to check that the filters are compatible with your HVAC system. Some filters may not fit properly or may be too restrictive, which can strain your system and reduce its efficiency.

Frequently Asked Question

Changing your furnace filter is a must for improved air quality and lower energy bills. The general rule is to switch it out every 90 days, though your lifestyle and the type of filter you choose may require you to change it more often. Keep an eye out for signs that it's time for a new filter. If your furniture gets dusty quickly or your furnace runs longer than usual, the filter may be clogged and no longer effective.


Fortunately, changing the filter is a simple process. Loosen the screws on the filter cover if it's located behind a return-air vent, or pull it out from the side of the furnace if it's in a slot. Have a trash bag ready as the filter will be dirty and can be discarded with your regular trash. Then, insert the replacement filter into the empty slot and mark your calendar for the next switch.


Making sure you have a clean furnace filter is essential for optimal air quality and energy efficiency. Follow the guidelines and watch for signs that the filter needs to be replaced, and you'll be able to enjoy the benefits of a clean filter in no time.

Air filters come in all sorts of shapes and sizes, and they are referred to in different ways - Nominal Size and Actual Size. So what's the difference?


Actual Size is the exact dimensions of the air filter. So, if you measure your filter, it may measure 15-1/2' x 24-1/2' x 7/8' (15.5' x 24.5' x .875'). This size is important to know, but it's not usually labeled this way. Most filters (but not all) are a bit smaller than the size they are listed as - this is where Nominal Size comes in.


Nominal Size is the size that the air filter is labeled as. In our example, the 15-1/2' x 24-1/2' x 7/8' (15.5' x 24.5' x .875') would be labeled as a 16x25x1. This is the size you would order.


There is one exception - air cleaner filters. Occasionally, they can be larger than the nominal size. For example, the Honeywell FC100A1003 is labeled as a 16x25x4 air filter, but the actual size is 16' x 19-7/8' x 4-3/8' (16' x 19.875' x 4.375') - thicker than the 4 inch nominal listing. So be careful when ordering replacement filters for name brand air cleaners!

Are 4-inch air filters worth it? The answer is a resounding yes! A 4-inch thick air filter offers numerous benefits over a 1-inch filter, including improved airflow, greater longevity, and maximum filtration potential. Plus, at FilterBuy, the price difference between the two is minimal. Therefore, if it fits your furnace, a 4-inch air filter is definitely worth the investment.


But what if the air filter compartment in your furnace is only 3” thick? In that case, a 1-inch furnace filter is the better choice, followed by the 3-inch filter. If the only difference is thickness, then the 2-inch filter is the one to go with.


It's important to always use the thickest air filter you can, as it will offer the most efficiency. However, never try to force a filter into a space that it's not designed for, as this can cause damage to the system and lead to decreased efficiency. 


When dropping down by an inch, such as using a 4-inch filter instead of a 5-inch, the difference shouldn't be too significant. On the flip side, using a 1-inch filter in a compartment that can accommodate a deeper filter may cause a loose fit, allowing unfiltered air into the ductwork.

Let's start with the basics: a three to four-inch filter should be replaced every six to nine months. But if you've got a thicker, five to six-inch filter, you'll get up to twelve months out of it. Keeping your filters clean and up-to-date is essential for peak performance from your heating and cooling system, as well as for clean air you can breathe easy.


To make sure your filter is in tip-top shape, check it every month. If it's time for a replacement, you'll notice an off-white color with visible dust and particles collected.


Not sure what size filter you need? The best thing to do is consult your manufacturer. Using a filter that's too thick for your system can impede air flow, so be sure to get the right size. If you want to upgrade your filter, you can have a filter cabinet installed. This allows for a higher efficiency filter, while still giving you easy access to check or replace it.


No matter your needs, our HVAC professionals can help. They'll give you a recommendation on the best filter for your system and household, and even install the cabinet if you need it.

When it comes to air filters, it can be hard to decide which size to go for. With so many options available, one of the most frequent questions we get asked is ‘what size air filter do I need?’


Air filter sizes are determined by the thickness, length, width and height of the filter. Generally, most air filters are 1 or 2 inches thick. However, you may find some that are between 3 to 6 inches in thickness. Thicker filters are more efficient, and they also last longer as they have a larger surface area to trap and remove air pollutants.


A 1-inch air filter needs to be replaced monthly, while a 4-inch filter can go six months without needing a substitute. However, replacement schedules differ depending on the brand and type of air filter.


In some homes, you may find 2-inch filters, and if you need a 3-inch filter, you have a one-of-a-kind HVAC system. 4, 5 and 6-inch air filters are typically found in whole house filters installed into an air handler, which is near your HVAC system.


Thicker air filters, such as 4 to 5 inches, are better in terms of providing a tight fit that prevents dirty air from passing through. They are less restrictive, so more filtered air can pass through and this offers better filtration.


So, to sum it up, 1 and 2-inch air filters are used in standard HVAC systems, while 3 to 6-inch filters are installed in larger HVAC systems. Ultimately, the filter size you choose depends on the type and size of your HVAC system.
