Are Your 16x25x4 Air Filters Putting You at Risk?

Have you ever stopped to think about the air that you and your loved ones breathe in your home? You might have thought about the quality of outdoor air, but what about indoor air? It might surprise you to know that indoor air can be two to five times more polluted than outdoor air.

Worse still, if you're using 16x25x4 air filters in your HVAC system, you could be putting yourself and those you love at risk. In this article, we'll explore the dangers of using 16x25x4 air filters in your home and what you can do to protect yourself and your family.

From the risks of mold growth and bacterial buildup to allergens and pollutants in your air, we'll delve into the science behind air filtration and how to ensure you have the right air filters in your home.

The Dangers of Using 16x25x4 Air Filters

Are you aware that your 16x25x4 air filters could be putting you at risk? Most people don't think twice about their air filters, but the truth is that they play a significant role in the quality of the air you breathe. In this section, we'll discuss the dangers of using 16x25x4 air filters.

Firstly, these filters contribute to poor indoor air quality. They may catch larger particles like dust and pet dander, but they're not efficient enough to capture smaller allergens like pollen and mold spores. This means that these allergens will continue to circulate in the air, leading to allergy symptoms such as sneezing, coughing, and itchy eyes.

Secondly, 16x25x4 air filters can also be a breeding ground for mold and bacteria. When these filters become clogged with dirt and debris, they provide the perfect environment for mold and bacteria to grow. This can lead to a musty smell in your home, as well as more serious health issues if left unchecked.

Lastly, 16x25x4 air filters simply aren't efficient enough to remove small particles. Studies have shown that these filters are only able to capture particles larger than one micron in size. Unfortunately, many harmful particles like bacteria and viruses are much smaller than this, so these filters are essentially useless in protecting your indoor air quality.

In conclusion, if you care about your health and the quality of the air you breathe, it's time to switch to a more efficient air filter. Don't put yourself or your family at risk by using 16x25x4 air filters.

The Science Behind Air Filtration

It's important to understand how air filters work in order to select the right one for your specific needs. Air filters are designed to remove airborne particles and pollutants from the air in your home or building. As air flows through the filter, these particles are trapped and prevented from circulating throughout your space.

The MERV, or Minimum Efficiency Reporting Value, rating system is used to measure the effectiveness of air filters. The higher the MERV rating, the more particles the filter is able to capture. Filters with a MERV rating of 11 or higher are recommended for those with allergies or respiratory issues.

Selecting the right air filter for your specific needs is crucial. Factors such as the size of your space, the type of pollutants present, and the frequency of filter changes all play a role in determining which filter is best for you. Consult with a professional to determine the right filter for your home or building.

Don't let your 16x25x4 air filters put you at risk. Take the time to understand the science behind air filtration and select the right filter for your specific needs to ensure you're breathing clean, healthy air.

3. How to Choose the Right Air Filter

When it comes to selecting the right air filter, there are several key factors to consider. Here are some important things to keep in mind:

Understanding MERV Ratings

MERV stands for Minimum Efficiency Reporting Value, and it's a rating system that measures the effectiveness of air filters. A higher MERV rating means the filter can capture smaller particles and pollutants, but it can also affect the airflow in your HVAC system. It's important to choose a filter with a MERV rating that's appropriate for your needs and your HVAC system's capabilities.

Choosing Between Disposable and Washable Filters

Disposable air filters are the most common type and are relatively inexpensive to replace. They're easy to install and don't require any cleaning, making them a convenient choice for many homeowners.

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.
