How to Choose a Good Air Filter?

A range of home air filters differs in size, materials, efficiency, and design. Since an air filter’s job is to capture dust and debris to reduce the amount of pollution, you must choose the best air filter that will give the best protection against air irritants. The right air filter projects the heating and cooling system from potential damage. This section of the article will help you to know different things to consider while purchasing air filters. 

Size of the Filter

First, you have to figure out which size air filter you need for your system, For example 10x10x0.5 air filter. Air filters are typically placed next to the furnace or air handler. Once you choose a good air filter, ensure it fits in your system perfectly. To determine the right size of the filter, measure the height, width, depth, or thickness of the place you want to set up the filter. If the existing filter is perfect-fit, write down its size on the filter’s frame. Check the manual to know the proper dimension of the filter. 

The amount of Filtration Level 

Every HVAC filter improves indoor air quality by filtering out small particles, but too-dense filters make it harder to heat and cool the house efficiently. In extreme cases, it may even damage the furnace. Therefore, consider the right amount of air filtration level of your air filter that allows ample airflow through the air ducts while trapping air allergens. If you want to know the airflow requirements of your HVAC system, you should measure the static pressure. 

MERV Rating

The Minimum Efficiency Reporting Value of MERV rating measures an air filter’s performance in capturing the number of airborne particles. The higher the MERV rating is, the better a filter can capture smaller particles. Filters with MERV 5 to MERV 8 ratings are suitable for residential settings. You may choose higher ratings for bigger commercial settings. 

Different Types of Air Filters

Depending on your HVAC system’s requirements, you have to choose the suitable air filter model within your budget.
