>You’ve probably noticed that your home smells a bit musty sometimes. This is due to dust, bacteria and other contaminants that get trapped in your HVAC system. To prevent this from happening, you need to clean your HVAC system regularly with the help of a MERV filter. However, these filters need to be replaced on a regular basis in order to keep your HVAC system working optimally. If you don’t clean your HVAC system regularly, it can lead to excessive build-up of bacteria, dust and other contaminants that can make your home smell unpleasant. Therefore, it’s important that you know how long you can expect to use each filter before replacing it with a new one. There are different types of MERV filters that are suitable for different types of HVAC systems. Let’s take a look at some of them:

What is a MERV Filter?

A MERV filter is a type of air filter that is designed for the removal of airborne particles. These filters are used to clean and protect the indoor air quality of a building. They are often used in heating, cooling, ventilation and air-conditioning systems. The MERV number refers to the effectiveness of the filter in removing dust, pollen, bacteria and other contaminants from the air. This is measured on a scale from 1 to 19, with 1 being the least effective and 19 being the most effective. MERV filters are used in many different environments, including offices, schools and hospitals. They are also commonly used in domestic and commercial HVAC systems.

How do you know when to replace your MERV filter?

The lifespan of each type of filter varies depending on the type of HVAC system that you have. Generally, you should replace your filter once a month. If you have a large family or if you have pets, you should probably replace your filter every two weeks. If you live in a particularly dusty area, you may need to replace your filter more frequently. It’s also important to note that you should never run your HVAC system without a filter. This can lead to excessive wear on the system and cause premature breakdown. This can also be very unhealthy for you and your family.

What are the different types of MERV filters?

There are a number of different types of MERV filters that are suitable for different types of HVAC systems. Let’s take a look at some of the most popular ones:

  • MERV 11: This is a medium-capacity filter that is designed to remove dust and larger dust particles from the air. These filters are commonly used in central air systems.

  • MERV 13: This is a medium-capacity filter that is suitable for central air systems, ductwork and portable air-conditioning units. These filters are commonly used in offices, schools and other commercial buildings.

  • MERV 16: This is a high-capacity filter that is suitable for large central air systems, ductwork and portable air-conditioning units. These filters are commonly used in offices, schools and other commercial buildings.

  • MERV 20: This is a high-capacity filter that is suitable for large central air systems, ductwork and portable air-conditioning units. These filters are commonly used in offices, schools and other commercial buildings.

Conclusion

MERV filters are important for keeping your home or office clean and healthy. They are designed to trap dust, bacteria and other contaminants in the air and prevent them from entering the rest of the building. These filters should be changed regularly to ensure that your air is clean and healthy. If you don’t replace your filters, the build-up of dust, bacteria and other contaminants can make your home or office unpleasant to be in. It’s important to know when to replace your filter so that you can keep your home or office clean and healthy.

Frequently Asked Question

MERV stands for Minimum Efficiency Reporting Values. This determines a filter’s ability to capture particles between .3 and 10 microns. This tells the buyer how far a certain type of filter can screen airborne particulate matter.
Usually, it would depend on the type of setting of a household. If the location is dry or if there are pets inside the house. In general, a MERV rating of 8-10 is already good for residential purposes. This type of filter can capture airborne particles and improve your air quality without compromising your budget for replacement and HVAC performance.
HEPA air filters and MERV-rated filters are different. HEPA filters exceed the ASHRAE test protocol used when determining the MERV ratings. HEPA filters are the only air filters that have been tested and certified in meeting a specific efficiency at a particular size.
They both differ in their particle arresting. MERV 11 furnace filters perform up to 90% particle arresting. The MERV 13 HVAC filters, on the other hand, have a capacity of about 98% which makes them more efficient. The MERV 11 is recommended for residential spaces in the moderately polluted area who owns a pet and has mild allergies.
