1. What do MERV 8 and MERV 11 air filters actually do?

Air filters are essential components of any indoor heating, ventilation, and air conditioning (HVAC) system. They work by capturing and removing pollutants, such as dust, pollen, pet dander, and debris, from the air before it is circulated throughout your home or workplace.

MERV, or Minimum Efficiency Reporting Value, is a rating system used to measure an air filter's effectiveness at removing particles from the air. The MERV scale ranges from 1 to 16, with a higher number indicating a higher level of filtration.

MERV 8 air filters are designed to capture small to medium-sized airborne particles, such as pollen, pet dander, and dust mites, and have a capture rate of 70% to 85%. These filters are typically used in residences or commercial buildings with minimal pollutant sources.

On the other hand, MERV 11 air filters are designed to capture smaller and more harmful pollutants, such as bacteria, viruses, and smoke particles. They have a capture rate of 85% to 95% and are typically used in commercial or industrial settings where pollutants are more significant.

Overall, air filters play an important role in maintaining good indoor air quality and preventing respiratory issues. It's important to choose an air filter with the appropriate MERV rating for your specific needs to ensure optimum air filtration.

2. The differences in filtration efficiency between MERV 8 and MERV 11

When it comes to air filters, the MERV rating system is used to measure their effectiveness in catching airborne particles. The higher the MERV rating, the better the filtration efficiency. MERV 8 filters are designed to capture particles as small as 3 microns in size. This includes pollen, dust, pet dander, and other common airborne allergens. However, MERV 8 filters may not be effective in capturing smaller particles such as smoke, viruses, and bacteria. On the other hand, MERV 11 filters are more effective in capturing smaller particles, including smoke and some types of bacteria. They are designed to capture particles as small as 1 micron in size, making them a good choice for individuals who suffer from respiratory issues or live in areas with high levels of pollution. While MERV 8 filters are more affordable than MERV 11 filters, they may not be enough for individuals who require higher levels of filtration. Choosing the right MERV rating for your air filter ultimately depends on your specific needs and the air quality in your area. It's always important to consult with a professional HVAC technician to determine the best air filter for your home or office. They can provide expert advice and ensure that your HVAC system is working efficiently to keep you and your family healthy and comfortable.

The Lifespan of MERV 8 vs. MERV 11 Air Filters

When it comes to air filters, one crucial factor to consider is their lifespan. The lifespan of an air filter depends on various factors, such as indoor air pollution levels, usage, and the filter's MERV rating. Generally, MERV 11 filters have a shorter lifespan than MERV 8 filters. This is because MERV 11 filters have smaller pores that trap more small particles. As a result, the filter clogs up faster, reducing airflow and efficiency, and needing frequent replacements. On the other hand, MERV 8 filters have larger pores that capture larger particles, allowing for greater airflow and better energy efficiency. While MERV 8 filters trap fewer particles, they last longer due to less frequent clogging. The lifespan of an air filter also depends on how often the filter is used. If the filter is used every day or for extended periods, it will wear out faster than one used occasionally. Regularly replacing air filters is essential to maintain good indoor air quality and the longevity of your heating and cooling systems. In conclusion, while MERV 11 filters have a higher efficiency rating, they generally have a shorter lifespan than MERV 8 filters. MERV 8 filters, on the other hand, trap fewer particles but last longer, making them a good option for homeowners looking for cost-effective and efficient air filters. It is essential to check and replace air filters regularly to maintain air quality and extend the lifespan of your HVAC systems.

Cost considerations for MERV 8 and MERV 11 air filters

When it comes to choosing between MERV 8 and MERV 11 air filters, cost is an important factor to consider. MERV 8 filters are generally less expensive than MERV 11 filters.

However, it is important to note that MERV 11 filters are more efficient in removing airborne contaminants like pollen, dust, and pet dander. This means that they can provide better indoor air quality and potentially reduce respiratory issues caused by poor air quality.

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.
