How to Install a Merv 11 Filter and Breathe Cleaner Air

Are you tired of living in a home with stale, polluted air? You don't have to suffer anymore. Installing an air filter is an easy and effective way to improve the air quality in your home. But not all filters are created equal. In this article, we'll show you how to install a Merv 11 filter so you can breathe cleaner air.

Many homeowners aren't aware of the importance of air quality, but it can have a significant impact on your health and wellbeing. Poor air quality can lead to respiratory problems, allergies, and even cardiovascular disease. Fortunately, installing a high-quality filter can help protect your family from these issues.

Not all filters are created equally, however. A Merv 11 filter is a step above the standard filter and is highly effective at removing pollutants from the air. With our step-by-step guide, you'll be able to install a Merv 11 filter in no time and start breathing cleaner air in your home.

Gather Supplies and Determine Filter Size

Before installing a Merv 11 filter, you need to gather a few supplies. Here's what you'll need:

  • Merv 11 air filter (The size will depend on the dimensions of your furnace or air conditioning unit. Check your owner's manual or the current filter for the correct size.)
  • Screwdriver
  • Clean rag

After gathering your supplies, you'll need to determine the size of your air filter. Typically, the dimensions are printed on the filter itself, but if not, you can measure it yourself. Use a tape measure or ruler to measure the length, width, and thickness of the filter. Record these numbers, because you'll need them when purchasing the new filter.

It's important to ensure that you purchase a Merv 11 filter that fits your furnace or air conditioning unit properly. A filter that's too small won't do its job effectively, and one that's too large won't fit snugly, which can reduce airflow and cause your system to work harder, leading to increased energy bills.

Once you have determined the correct size of your air filter, it's time to replace the old one with the new Merv 11 filter.

Shut Off Your HVAC System and Remove Old Filter

Before installing a new MERV 11 filter, it is crucial to shut off your HVAC system and remove the old filter. This step is necessary to prevent dust and other particles from circulating in your indoor air during the filter replacement process.

To turn off your HVAC system, locate the circuit breaker or power switch and flip it to the "off" position. This step ensures that the system is completely powered down and won't accidentally turn on while you are replacing the filter.

Next, locate the air filter and remove it from its housing. Depending on your HVAC system, the filter may be located in the return air grille, the air handler unit, or the furnace cabinet. Refer to your system's user manual for specific instructions on how to remove the filter.

Once you have removed the old filter, take a moment to inspect it for dirt, debris, and other contaminants. If the filter appears dirty or clogged, it's a sign that your HVAC system may not be circulating clean air effectively.

Dispose of the old filter properly and avoid touching the dirty side with your hands. Most filters can be recycled or disposed of along with your regular trash.

With the old filter removed, you're now ready to install your new MERV 11 filter and breathe cleaner, healthier air in your home or office!

Insert Merv 11 Filter and Ensure Proper Alignment

Now that you have chosen the Merv 11 filter, it's time to install it properly. Before changing the filter, turn off your HVAC system to prevent any debris or dust from circulating in the air.

Next, locate the filter compartment. The filter compartment is usually found on the side of your furnace or on the ceiling. Depending on the model of your unit, you might need to remove a panel or a cover to access the compartment.

Once you have access to the filter compartment, you can remove the old filter by gently pulling it out. Inspect the old filter to see if it needs to be replaced or cleaned. If it's dirty or damaged, dispose of it properly and move on to the next step.

Take the new Merv 11 filter and ensure that the airflow arrows on the filter frame are pointing towards the furnace or air handler. Slide the new filter into the compartment, making sure that it fits snugly and there are no gaps or air leaks.

Finally, replace the cover or panel back onto the filter compartment and turn on your HVAC system. It's recommended to check the filter once a month and replace it every three months or sooner if you have pets or live in a dusty environment.

By installing a Merv 11 filter and ensuring proper alignment, you can breathe cleaner air and improve indoor air quality. Not only will this benefit your health, but it will also help prolong the lifespan of your HVAC system.

Turn on Your HVAC System and Monitor Performance

Now that you have installed the Merv 11 filter, it's time to turn on your HVAC system and monitor its performance.

First, it's important to understand that the Merv 11 filter may cause some restrictions in airflow. This is because it's designed to trap smaller particles and therefore may require more energy to move air through it. However, this should not be a significant problem as long as your HVAC system is properly sized for your home.

After turning on your HVAC system, monitor the airflow coming from your registers. If it's weaker than usual, check the filter to make sure it's properly installed and not clogged. If the system seems to be struggling, you may need to consult an HVAC professional to assess the problem.

It's also important to track the performance of your Merv 11 filter over time. Check the filter every 30 days and replace it as needed. Pay attention to any changes in the airflow, as this could indicate a clogged filter or other issues with your HVAC system.

By regularly monitoring your HVAC system and filter, you can ensure that you are breathing clean and healthy air in your home.

Why Regular Filter Replacements are Important

Installing a Merv 11 filter in your HVAC system is a great step towards breathing cleaner air in your home. However, it is not enough to simply install the filter and forget about it. Regularly replacing your filter is essential to maintaining the quality of your indoor air.

Over time, filters become clogged with dirt, dust, and other pollutants. When this happens, the filter is no longer able to effectively capture and trap these contaminants. As a result, the air in your home becomes more polluted and can lead to health problems like allergies and asthma.

Additionally, a dirty filter can put a strain on your HVAC system, causing it to work harder and use more energy. This can result in higher energy bills and even damage to your system.

By regularly replacing your Merv 11 filter, you can keep your indoor air clean and your HVAC system running efficiently. Most manufacturers recommend replacing your filter every 90 days, but this can vary depending on your individual circumstances.

Bottom line: Don't skimp on regular filter replacements if you want to breathe cleaner air and keep your HVAC system in good condition.

Frequently Asked Question

A MERV 11 filter is a mid-range air filter, suitable for most residential and commercial buildings. It is ideal for households with pets or mild to moderate allergies or asthma. The MERV 11 filter is capable of trapping 85% of micron-sized airborne particles, which helps to improve indoor air quality and maintain the efficiency of the HVAC system. If you don't have any special needs, then a MERV 8 filter is usually sufficient.


The only standardized filter rating system is MERV, which stands for “minimum efficiency reporting value”. Developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers, the rating scale indicates how effectively a filter can stop particles from entering your home. The higher the MERV rating, the better the filtration and the more the HVAC system needs to work to overcome the filter’s back pressure.


For residential and commercial use, MERV ratings 8 to 13 are best. MERV 4 to 6 are only suitable for industrial applications, while MERV 14 to 20 are used primarily in hospitals and laboratories. HEPA filters, which aren’t included in the MERV rating system, are equivalent to a MERV 17 to 20 rating. Lastly, there are other rating systems like MPR (Microparticle Rating) and FPR (Filter Performance Rating) but these are not independent consumer standards.


When it comes to choosing the right furnace filter for your home, there’s no one-size-fits-all answer. To ensure that you make the best choice for your specific needs, you must consider various factors such as price, size, brand, and, most importantly, the MERV rating.


MERV stands for Minimum Efficiency Reporting Value, which is a rating system from 1 to 16 used to indicate how well the filter can capture airborne impurities. A MERV rating of 1 indicates the lowest efficiency, and 16 indicates the highest. MERV 8 and MERV 11 are two of the most popular ratings for residential use, as they are effective at trapping a majority of airborne particles.


So, which is better — MERV 8 or MERV 11? A MERV 8 filter is more affordable and perfect for filtering out large particles, but won't be as effective at capturing odors or small particles as a MERV 11 filter. MERV 11 filters are more expensive, and need to be replaced more often due to clogging, but can effectively reduce odors and capture small particles.


For the homes located in a polluted area, or those with pets or family members with allergies, a MERV 11 filter is the best choice. But if you don't fit into either of those categories, then a MERV 8 filter should suffice.


It is essential to keep in mind that the MERV rating for a filter is its minimum performance, and choosing the right one for your home will ensure that your HVAC system is functioning optimally.


Are you wondering what the difference is between MERV 11 and 13 furnace filters? Let us break it down for you.


MERV 11 filters are the most popular among residential users, and they can trap the majority of harmful contaminants in the air – this includes pollen, dust, lint, mold, dust mites, smoke, pet dander, and smog.


On the other hand, a MERV 13 filter is capable of capturing all of the particles that the 11 can, plus bacteria and viruses. This is due to its higher efficiency of particle arrestance (98%) compared to the 11 (90%).


When it comes to which one is better, it really depends on your needs. A MERV 11 is good enough for those living in moderately polluted areas, or those with mild allergies. But if you're in a heavily polluted area, or suffer from severe allergies/asthma, or own multiple pets – then the MERV 13 is the way to go.


No matter which rating you pick, it's important to remember to replace your filter periodically. Doing so will help ensure that your furnace remains in top shape for years to come.


MERV 11 air filters are more effective than MERV 8s, trapping smaller particles like pet dander, dust mites, auto-emissions and lung-damaging dust. This makes them a great choice for households with pets or those wanting improved air quality. It's also the most popular air filter option.


If you're looking for a middle-ground between MERV 8 and 13, MERV 11 is the perfect option. It’s more efficient than the 8, but cheaper than the 13, and won’t put extra pressure on your furnace due to its less dense material. Your furnace will last longer and your air will be healthier!


Before settling on a MERV rating, check your furnace's manual or info stickers to see what its max MERV rating is. Selecting an air filter with a higher rating than your system can handle can cause your furnace to work harder, increasing the risk of a breakdown.


MERV ratings are a standard that measure how well air filters work. The higher the rating, the finer the filtration, meaning fewer allergens, dust, and other contaminants can get through. Filters are tested for things such as pollen, dust mites, mold spores, pet dander, bacteria, tobacco smoke, and more.


Merv 8, 11, and 13 filters should be changed at least every three months. This is to ensure that your system doesn't get clogged, reducing its efficiency or damaging it. However, changing your filter every two months will give you even better filtration and healthier air in your home.


In short, the more often you change your MERV 11 filter, the better. A recommended minimum is every three months, but changing it every two months is even better for your home's air quality.
