HVAC filters should be changed at least every three months or as needed. If the filter looks visibly dirty, it should be changed immediately. Determining if a filter needs to be changed can also be based on when the resistance of the air filter reached the recommended maximum pressure drop recommended by the manufacturer. Gauges to determine pressure drop are most often found on larger commercial systems.

An HVAC air filter is a device that is used to capture airborne particles and contaminants from the air that passes through your air conditioning or heating system. The filter traps particles such as pollen, dust, pet dander, mold spores, and other allergens, which can help improve the air quality in your home or business.

If a HVAC filter is dirty, it can cause a number of problems. The most serious issue is that it can restrict airflow, causing the system to become less efficient and potentially overheat. This can also cause dust, dirt, and other airborne particles to get circulated through the home, leading to poor indoor air quality. Additionally, a dirty filter can cause dust and debris to build up in the system, leading to further problems.

The best air filters for HVAC systems in Boston depend on the application. Commercial buildings typically use MERV-rated filters (MERV 8–13), while hospitals, labs, and cleanrooms often require HEPA filters. Airex Filter helps Boston facilities select the right filter based on performance, airflow, and compliance requirements.

No, it is not recommended that you change the air filter while the air conditioner is running. Doing so could lead to system damage, and it could also cause air quality issues due to the disruption of the air flow. Additionally, changing the air filter while the air conditioner is running can also be dangerous, as you could be exposed to electrical shocks.

The steps for changing the air filter in an HVAC unit will vary depending on the type and model of unit you have. Generally, the steps to follow are: Locate the air filter: The air filter is usually located in the return air duct of the HVAC system. Remove the old filter: Remove the old filter from the unit and dispose of it properly. Install the new filter: Insert the new filter into the unit and make sure it is properly secured. Close the unit: Close the unit and make sure all connections and seals are secure. Turn on the unit: Turn on the unit and make sure it is working properly.

The number of filters an HVAC unit has depends on the type and size of the unit. Generally, residential HVAC systems have one to four filters. Commercial HVAC units usually have four or more filters, depending on the size and complexity of the system.

HEPA filters capture 99.97% of particles at 0.3 microns and are used in critical environments like healthcare and cleanrooms. Standard HVAC air filters, such as MERV-rated filters, are designed for general air quality and system protection in commercial and residential buildings.

Airex Filter offers both standard and custom air filter sizes. Custom filters can be manufactured to match exact dimensions for any HVAC system.

To choose the right air filter, consider the filter's size, MERV rating, and compatibility with your HVAC system. Higher MERV ratings indicate better filtration but may restrict airflow in some systems.
