There are several different types of furnace filters. The most affordable one is the disposable pleated type. These filters are available in several different sizes and MERV ratings. To find the right filter for your furnace, you must first determine what type of filter is right for your home. Then, you should consider the size of the filter.
Disposable pleated is the most affordable
While fiberglass furnace filters are cheap and easy to install, they don't do much to improve the quality of air you breathe. While they do keep larger particles from entering the system, they can also increase airflow resistance, which makes your HVAC system work harder and cost you more money in the long run. A higher quality furnace filter has a pleated surface that traps a greater variety of particles. High-efficiency disposable pleated filters, on the other hand, are a more effective option. Compared to fiberglass filters, these filters have a higher MERV rating and can remove minute particles.
There are several types of furnace filters on the market, with the most affordable being disposable pleated filters. Disposable pleated filters are made of paper and polyester and are often the cheapest option. These filters tend to have a longer lifespan and do a better job of blocking large particles than other types of filters.
Dimensions of a furnace filter
Before you buy a furnace filter, it's helpful to know the dimensions of the one that's currently in your furnace. Typically, you can find this information on the side of the filter frame. The dimensions of a furnace filter are in inches, and are usually measured in multiples of 1 inch. You can also check the dimensions online.
There are many factors to consider when changing a furnace filter. You can either go with the same model as the one you currently have or try out a new one. Or, you can choose to go with a different material or get a more advanced air cleaner. In any case, you must know the dimensions of a furnace filter so that it can fit properly in your furnace.
MERV rating
The MERV rating of your furnace filter is an important factor to consider when choosing a new filter for your heating system. Higher ratings are better for improving indoor air quality. You should look for a MERV rating of at least 13 and preferably higher. Filters with lower ratings can cause your HVAC system to run at less than its maximum capacity.
The MERV rating of a filter is determined by how well it filters particles of different sizes. To calculate MERV ratings, filters were tested in a laboratory environment. Particles sized 0.3 to 10 microns were measured. Then, these particles were grouped into three size ranges. The first range contains particles that are smaller than a human hair. The second range contains particles between 1.0 and 3.0 um and the third range contains particles that are larger than 10.0 um.
Direction of air flow
One of the most important things to remember when choosing a new furnace filter is the direction of air flow. The direction of air flow will determine which filter you need and which will not. You can identify the direction of air flow by looking at an arrow on the filter. It will be pointing toward your furnace or the return duct.
The direction of air flow can also be determined by the orientation of the filter in your furnace. In upflow furnaces, the arrow should point upward, while downflow furnaces should be pointed downward. Look for a direction arrow printed on the filter frame, as well. If you're unsure, you can also do a string test to confirm the direction of air flow.
