Should I Get a 1 or 4 Furnace Filter?

When it comes to furnace filters, size does matter. If it fits your oven, a 4-inch air filter is the better choice than a 1-inch air filter for improving air quality. At FilterBuy, the price difference between 1-inch and 4-inch air filters is usually only a few dollars, and because a 4-inch filter lasts longer, it usually offers a better value. From an economic standpoint, a 4-inch filter can save you a few dollars. However, filters of 4 inches or thicker are the most cost-effective option.

In addition, they will give your heating system better health and efficiency. The four-inch-thick air filter has an advantage over the one-inch one in terms of longevity, airflow, and maximum filtering potential. If it fits your oven, a four-inch air filter will provide better air quality. The difference in costs is usually minimal. So, if you're looking for the best value for your money and improved air quality, then a 4-inch air filter is the way to go. When it comes to furnace filters, an expert would recommend that you opt for the 4-inch filter over the 1-inch one.

Not only does it offer better value for money, but it also provides superior air quality and improved efficiency for your heating system. The cost difference between the two is usually minimal, so if you want to get the most out of your furnace filter investment, then go with the 4-inch option.
