How To Determine Which Filter to Buy for Your Furnace

Many people are not paying attention to the furnace system they have at home. As long as it keeps them warm during the winter season and cool during summer season, this would surely be enough. But, to keep the furnace system from working at its optimal performance and preventing unexpected malfunctions, you need to purchase the best filter for the model of the furnace that you have. This may sound simple but there are many furnace filter options for you to choose from.

How Furnace Filters Are Rated?

We all know that you should maintain your furnace annually. In order to determine which filter to buy for your furnace system model, you need to take a closer look at the minimum efficiency reporting value. This is also known as the MERV ratings. Most of the MERV ratings of filters range from 1 to 16. The higher the MERV rating of the filter, the higher is the quantity of the particles that the filter can remove.

Higher rated filters allow less amount of air to flow. This will eventually force your furnace to malfunction and work harder. MERV rating in between eight and eleven is best for homes. For you to be sure with the MERV rating of your filter, you need to determine the maximum MERV rating of your furnace model.

Filter Types

To determine the best filter to buy for your furnace model at home, you need to consider the different types of filters sold by different manufacturers. One of the most common types of furnace filter is a disposable pleated kind.  This kind of filter comes in its standard ratings and sizes. Lennox and Goodman are common brands
