MERV Rating Mistakes That Could Damage Your System

The extremely important part of your home's comfort is your HVAC system. It works hard every day to keep the air clean and healthy and the indoor temperatures just right. Whether it is a hot day of summer or a chilly evening of winter, your air conditioner and heating system depend on air filters to keep everything running smoothly. There are lots of different types of air filters available both online and on the market. MERV air filters are commonly used in homes, offices, and buildings. The full name of MERV is “Minimum Efficiency Reporting Value,” which tells you how well a filter can trap the harmful airborne particles like dust, dirt, pollen, mold spores, and pet dander. A higher MERV rating shows that the air filter is going to become more effective at capturing smaller particles in the air.

Thus, choosing a proper MERV rating air filter is extremely important. An air filter with a MERV rating that is too high can also cause blockage in the airflow, which will make your HVAC system work harder and possibly lead to damage. On the other hand, a filter with a rating that is too low might not be able to clean the air effectively, allowing allergens and dust to circulate through your indoor atmosphere. It is all about finding the perfect balance that suits your HVAC system and your needs. Understanding MERV ratings helps you make better choices for your indoor air quality and your HVAC system's health.

In this blog, you will get to explore the common mistakes that many people make with their MERV rating air filter and how you can avoid them. You will get to learn the mistakes, like installing air filters with high MERV ratings, using weak MERV air filters in a powerful HVAC system, forgetting to change the air filters from time to time, and ignoring the important guidelines of the manufacturer. Here, you will also gain knowledge about how a wrong MERV rating air filter impacts your HVAC system, the information that will help you to choose the best MERV rating air filter for your system, and lastly, how you can avoid the air filter mistakes by using the expert tips.

Top MERV Rating Mistakes to Avoid

There are many people who unknowingly make simple mistakes when choosing or using MERV-rated air filters. These mistakes might seem pretty small, but they can affect the performance of your HVAC system over time. There are a few common errors that are easy to avoid once you know what they are. Keep reading to learn how to avoid these common issues.

1. Installing Filters With High MERV Ratings

The very first mistake that lots of people make is using an air filter with a high MERV rating. While it might seem like a smart choice. However, in reality, it can cause multiple problems if your HVAC system is not built for it. These air filters are quite thick and can block the airflow, which makes your HVAC system work harder. This extra work can weaken the essential parts, like the motor, reduce efficiency, and lead to wear and tear over time. When the airflow is too low, it will even cause your HVAC unit to overheat or your air conditioner to freeze. High MERV rating air filters also cost more and will also require more frequent changes. So, always make sure that your air filter fits in your HVAC system and can handle it.

2. Using Weak MERV Filters In Powerful Systems

The second big mistake that people make is using a weak MERV filter in a powerful HVAC system. This can lead to poor indoor air quality and an increasing system workload. These air filters might not be able to catch dust, dirt, pollen, or allergens, which means contaminated air keeps circulating through your home or office and into the system. This will also lead to lowering the system’s performance and make it work harder than it should. As a result, you will get higher energy bills and risk damage to important parts like the blower motor. In some cases, the system may even overheat. Weak air filters can also allow moisture to build up, creating the right conditions for mold and mildew to grow.

3. Forgetting Filter Replacement Schedules

The next common mistake is forgetting to replace the air filters on time. It is extremely important as it can affect both the indoor air you breathe and the way your appliances work. When you use a dirty air filter, it can hold onto harmful particles and stop the system from working efficiently. This will lead to bad smells and poor airflow. Breathing in air full of dust and dirt will not only smell strange but also be harmful to your health. When filters stay clogged for too long, devices like HVAC systems may break down or use more energy. Regular filter changes help avoid these problems and keep your home cleaner and safer.

4. Overlooking Manufacturer Guidelines

The last mistake on this list is when a user fails to follow the manufacturer’s guidelines for the air filter. This big mistake can lead to several problems. Each HVAC system is built with certain needs, and using the wrong type of filter or installing it in the wrong way will affect how the system runs. This may lower the airflow and force the system to consume more energy. It can even damage the essential parts. Some air filters need to be changed more often or cleaned in a certain way. Skipping these steps can make your air filter less effective. To avoid poor performance or extra repair costs, it is always best to follow the instructions given by the manufacturer.

The Impact Of The Wrong MERV Rating On Your HVAC

When you use the wrong MERV rating air filter in your HVAC system, it will cause multiple problems. You might face problems right away or as time passes by. An air filter that is too thick can cause blockage in the airflow, which will make your HVAC system work even harder than it should. This will also lead to damage in the parts like the fan motor and compressor as they become weakened. It will also cause them to wear out faster or overheat. When airflow is restricted, it can also lead to uneven heating or cooling in your home, making the system less effective at doing its job.

If you continue to use the air filters that do not match your HVAC system, then over time, it will lead to higher energy bills. The main reason is that the HVAC unit consumes more power to run. However, when you use an air filter with a too low MERV rating, then your air filter will not be able to trap enough dust and allergens, which will eventually affect the air quality. It will also let dirt build up inside your HVAC system. This will not only reduce the efficiency of your HVAC system but will also become the reason for the breakdown, decreasing its overall lifespan.

Picking The Best MERV Rating For Your System

The choice of the right air filter with an MERV rating for your HVAC system is essential. By reading below, you will learn the key points that will help you choose the right filter for your needs.

• Know the MERV scale first: MERV ratings usually range from 1 to 20. For most homes, filters between MERV 8 and MERV 13 work well and do not put too much strain on the system.
• For general home use: MERV 8 to MERV 11 filters are great for trapping common dust, lint, and pollen. They are good for homes without pets or major health concerns.
• If you have allergies or asthma: Choose a MERV rating between 11 and 13. These filters trap finer particles like pet dander and mold, helping to improve air quality.
• If you have pets indoors: A filter with a higher MERV rating, like MERV 11 or 12, can help catch fur, dander, and pet-related dust. This keeps the air cleaner and your system running smoothly.
• Check your environment: If you live in an area with high pollution or pollen levels, a MERV 12 or 13 filter can help reduce indoor dust and improve breathing comfort.
• Always check your system manual: Your HVAC system has a limit on what MERV rating it can handle. Using a filter that is too strong can block airflow and reduce system efficiency.
• Think about filter thickness: A thicker filter has more space to catch dirt without blocking air. Filters that are 4 inches thick can often hold higher MERV ratings with less airflow resistance.
• Talk to a professional if unsure: If you are not sure what your HVAC system can handle, it is best to ask a technician. They can suggest a filter that fits your system and your needs.

Avoid Filter Mistakes With These Expert Tips

If you follow expert tips, you can easily avoid mistakes when picking and using MERV rating air filters. Below, you will see some simple and helpful tips from professionals that can keep your HVAC system running well and your indoor air clean.

• Verify the air filter's size: Use the perfect size air filter for your HVAC system at all times. A filter that is too big or too small will not work properly and may allow dust to pass through.
• Install it right: Make sure the filter is facing the right direction. Most filters have arrows that show airflow direction, so follow that to avoid problems.
• Check regularly: You need to make a schedule of looking at your air filter every month. If the air filter looks dirty or clogged, then it's time for you to replace it, even if it has not been three months.
• Buy in packs: Buying filters in bulk saves time and money. It also reminds you to change them more often because you already have a new one ready.
• Use good lighting: When checking your filter, you can use a flashlight to see the amount of dirt that is trapped. When the light is having trouble passing through, then it means that the air filter needs to be replaced.
• Write down change dates: Keep a small note on your HVAC unit or calendar. Knowing the last change date helps you stay on track and avoid overusing old filters.
• Keep the area clean: Clean around the HVAC system to reduce dust and dirt. Less mess around the unit means the filter does not have to work as hard.
