How to Choose the Right Furnace Filter

Choosing the right furnace filter for your home is an important decision. It's essential to select the correct size and type of filter to ensure your HVAC system runs efficiently and your home's air quality is improved. Here are some tips to help you choose the right furnace filter for your home. First, refer to your oven manual or existing filter to determine the correct size of filter you need. Make sure to turn off the oven before removing the existing filter, and use a permanent marker to draw an arrow on the outside of the oven indicating the direction of air flow.

This will help you remember which way to install the new filter. Next, consider the size of the oven filter, which will be printed on the cardboard frame. It's important to select a filter with a MERV rating between 9 and 12 in order to properly protect your HVAC system and home. If you're not sure which filter is right for your system, consult an HVAC contractor who specializes in furnace repair in St. Paul.When it comes to selecting an oven filter, it's important to consider airflow restriction or static pressure drop across the filter.

Choosing a filter with too much airflow restriction will cause your oven to work harder and could increase your energy bills and lead to increased equipment failure. Cheap woven fiberglass filters do one thing - remove dirt and debris that could damage your oven blower motor, while removing some of the pollen and mold spores. However, more expensive filters with higher MERV ratings can do more, such as trapping smaller particles like pet dander, smoke particles, and bacteria. The frequency with which you need to replace your oven filter will depend on the type you purchased and the air quality in your home. If you have pets or live in an area with high levels of air pollution, you may need to replace your filter more often. Selecting the right oven filter for your heating and cooling system is crucial when it comes to producing and maintaining a healthy, clean and pure home environment. With these tips in mind, you can make an informed decision about which furnace filter is best for your home.
