Your furnace filter is a key component to the maintenance of your home and health. The filter is your first line of defense against allergens, bacteria, dust, and other air pollutants that can be found in your home’s air. It is the job of your furnace filter to essentially filter out all of the pollutants that can cause poor air quality and negatively affect your health.
At Action Cooling & Heating in Fort Meyers, Florida, we help perform routine air filter maintenance for your convenience. It is important that you replace your filter every 90 day. However, replacing the filter routinely is not enough. You also need to make sure you choose the right one. Action Cooling & Heating of Fort Meyers shows you what to consider when selecting your new air filter.
Furnace filters come in a variety of sizes. This makes sense as there are a number of furnaces for different types of buildings and needs. The most common filter sizes are 14”x 25”, 16”x 20”, 16”x 25”, 20”x 25”, and 25”x 25; however it’s possible your furnace will filter will not fit into one of these sizes. It’s important you get the right filter size to prevent air from flowing around the edges and not through the filter as intended. You can locate your filter size by checking the filter cabinet door.
Additionally, the thickness, or depth, of your filter is also important. You want your filter to fit snugly in place and not loose fitting. The general thickness for filters is 1” to 5”.
One of the key components to choosing the right filter is the efficiency of the new filter. This can easily be determined by the MERV (Minimum Efficiency Reporting Value) system. Every furnace filter has a MERV rating. This measures how efficiently the furnace filter captures particles through it as your furnace operates. The MERV rating system ranges from 1 (least efficient) to 16 (extremely efficient). Choosing a MERV rated 10 for your filter is good for the average household. However, the need changes as you factor in pets and residents with allergens.
You may not always find the filter you need. Some units have custom furnace filters that require special ordering from a manufacturer. For more information regarding routine air filter changes or other services from Action Cooling & Heating in Fort Meyers, be sure to visit the website.
