Installing a combined air filter in an existing air handling unit is a crucial step in enhancing the air quality and efficiency of your HVAC system. As a leading supplier of combined air filters, I'm here to guide you through the process, sharing valuable insights and practical tips to ensure a successful installation.
Understanding the Importance of Combined Air Filters
Before diving into the installation process, it's essential to understand why combined air filters are so important. These filters are designed to capture a wide range of airborne particles, including dust, pollen, mold spores, and even some bacteria and viruses. By removing these contaminants from the air, combined air filters help improve indoor air quality, reduce the risk of respiratory problems, and extend the lifespan of your air handling unit.
Combined air filters typically consist of multiple layers, each with a specific function. For example, the pre-filter layer captures larger particles, while the main filter layer traps smaller particles. Some combined air filters also include an activated carbon layer to remove odors and harmful gases.
Assessing Your Existing Air Handling Unit
The first step in installing a combined air filter is to assess your existing air handling unit. This involves determining the size, type, and configuration of the unit, as well as the location of the existing filter housing. You'll also need to check the airflow requirements of the unit to ensure that the new combined air filter is compatible.
To assess the size of the filter housing, measure the length, width, and depth of the opening. Make sure to measure accurately, as even a small discrepancy can prevent the new filter from fitting properly. You can also refer to the manufacturer's specifications for your air handling unit to find the recommended filter size.
Next, determine the type of filter housing you have. There are several different types of filter housings, including slide-in, pocket, and panel. Each type requires a specific type of filter, so it's important to choose the right one for your unit.
Finally, check the airflow requirements of your air handling unit. The airflow rate is typically measured in cubic feet per minute (CFM). You'll need to choose a combined air filter with a CFM rating that matches or exceeds the airflow rate of your unit. This will ensure that the filter can effectively capture airborne particles without restricting the airflow.
Choosing the Right Combined Air Filter
Once you've assessed your existing air handling unit, it's time to choose the right combined air filter. There are several factors to consider when choosing a filter, including the filter efficiency, the filter media, and the filter size.
The filter efficiency is measured by the Minimum Efficiency Reporting Value (MERV). The MERV rating ranges from 1 to 20, with higher ratings indicating greater filter efficiency. For most residential and commercial applications, a MERV rating of 8 to 13 is recommended. However, if you have specific air quality concerns, such as allergies or asthma, you may want to choose a filter with a higher MERV rating.
The filter media is the material used to make the filter. There are several different types of filter media, including fiberglass, polyester, and pleated paper. Each type of filter media has its own advantages and disadvantages, so it's important to choose the one that best suits your needs.
The filter size is also an important consideration. Make sure to choose a filter that is the right size for your filter housing. You can refer to the measurements you took earlier to find the correct filter size.

We also offer Glass Fiber Bag Air Filter for applications that require high-efficiency filtration.
Preparing for Installation
Before installing the new combined air filter, you'll need to prepare the air handling unit. This involves turning off the power to the unit, removing the existing filter, and cleaning the filter housing.
To turn off the power to the air handling unit, locate the circuit breaker or fuse box and switch off the power to the unit. This will prevent any electrical shocks or accidents during the installation process.
Next, remove the existing filter from the filter housing. Depending on the type of filter housing you have, you may need to use a screwdriver or other tools to remove the filter. Make sure to handle the filter carefully to avoid damaging it.
Once the existing filter has been removed, clean the filter housing. Use a vacuum cleaner or a damp cloth to remove any dust or debris from the housing. This will ensure that the new filter fits properly and functions effectively.
Installing the Combined Air Filter
Now that you've prepared the air handling unit, it's time to install the new combined air filter. Follow these steps to ensure a successful installation:
- Insert the filter into the housing: Carefully insert the new filter into the filter housing. Make sure that the filter is properly aligned and that it fits snugly into the opening.
- Secure the filter: Depending on the type of filter housing you have, you may need to use a clip, bracket, or other fastener to secure the filter in place. Make sure that the filter is securely fastened to prevent it from moving or falling out.
- Check the airflow: Once the filter is installed, turn on the power to the air handling unit and check the airflow. Make sure that the airflow is strong and that there are no signs of restricted airflow. If you notice any problems with the airflow, check the filter to make sure that it is properly installed.
Testing and Maintenance
After installing the new combined air filter, it's important to test the air handling unit to make sure that it is functioning properly. You can use an air quality monitor to measure the air quality before and after the installation to see if there is a significant improvement.
It's also important to maintain the combined air filter regularly to ensure that it continues to function effectively. This involves replacing the filter at regular intervals, as recommended by the manufacturer. You should also clean the filter housing periodically to remove any dust or debris that may accumulate over time.
