What is the Difference Between a Furnace Filter and an Air Filter?

Oven filters, also known as air filters, are essential components that not only keep the air in your home clean, but also help extend the life of your oven. Homeowners often have questions about them, such as how to replace an air filter, which filter they should buy, and more. If you're wondering which one to choose between an oven filter and a return air filter, you've come to the right place. We've researched to give you the answers you're looking for. Sometimes, air filters and other phrases such as air filters and oven filters are used interchangeably, leading to a misperception that they are the same thing or, in certain cases, completely different things.

Oven filters and return air filters (AC air filters) are not similar, but they are not completely different either. To help you choose the best solutions for your home air conditioner, we outline the main distinctions between return air filters and oven filters in your central air system below. The oven and return air filters are separate parts located in the blower compartment and the return grilles respectively. The main function of the oven filter is to protect the blower from dirt, sand, pet dander and other harmful substances. It is among the best types of AC filters due to its low cost, disposability, and ability to protect ovens and air conditioners from dirt.

If you have any questions about the air filter for your boiler and air conditioner, or if you want a cooling system repaired or installed in your home, contact Jerry Kelly Heating & Air Conditioning. Let's take a closer look at how your HVAC air filter works, what an air purifier is, and how they're needed for optimal indoor air quality. In most cases, the central air system uses two separate filters to properly filter unwanted particles, allergens, bacteria and more. When lung health is an issue or you simply want the cleanest possible air in your home, you need a stand-alone air purification apparatus. They offer less resistance to airflow and modest air filtration, but can effectively filter dust and other contaminants. Your oven has been working hard all winter, so now is the best time to change your air filter to keep up with that demand so your air conditioner can run efficiently when it's time to start keeping your home comfortable.

Air filters are an essential part of your central air system that allow you to safely clean hot or cold air as it circulates inside your home. You can describe the filter based on the current season - calling it an oven filter in winter and an air conditioning filter in summer. As for return air filters, they not only protect the HVAC system but also purify the air you breathe by removing various particles. However, this doesn't mean you should always choose the filter with the highest MERV rating as filters with higher MERV ratings can interrupt airflow in certain HVAC systems. It can also negatively affect indoor air quality (IAQ) if you don't routinely change or clean your air filter.

This is a good time to take a look at your air filter and see if it's ready to change it or not.
