If you have a furnace, you know that you need to change the filter regularly. But with all of the different types and sizes of furnace filters 16x25x1 on the market, it can be difficult to know which one to choose. Here are six factors to consider when purchasing a furnace filter to ensure you get the best one for your needs.

Filter Size

One of the most important factors to consider when buying a furnace filter is size. The size of the filter you need will depend on the size of your furnace. Be sure to measure your furnace before you go out and purchase a new filter so that you get one that fits properly. A too-small filter won't do a good job of trapping particles, while a too-large filter might restrict airflow and cause damage to your furnace over time.

Filter Efficiency Rating (MERV)

Another factor you'll want to keep in mind is the MERV rating of the furnace filter. Minimum Efficiency Reporting Value i's a way of measuring how well a filter captures particles in the air. A higher MERV rating means that the filter does a better job of trapping smaller particles, like dust mites, pet dander, and pollen. However, filters with high MERV ratings can also restrict air flow, so it's important to strike a balance between efficiency and airflow when choosing your filter.

Cost

Of course, the cost is also going to be a factor in your decision. Furnace filters range in price from $6-$30, depending on their size and efficiency rating. However, it's important not to let cost be the only deciding factor in your purchase. A more expensive filter isn't necessarily better—just be sure that you're getting a quality product that will meet your needs.

Material

Furnace filters are made from a variety of materials, including paper, fiberglass, and pleated fabric. The type of material you choose is mostly a matter of personal preference. Paper filters are the cheapest option, and they do a decent job of trapping particles. Fiberglass filters are also fairly inexpensive, but they're not as effective at trapping smaller particles. Pleated fabric filters tend to be more expensive, but they offer the best airflow, and they're very effective at capturing small particles.

Change Frequency

The frequency with which you should change a furnace filter is determined on the type of filter and the climate in which you reside. For example, if you have pets or live in an area with a lot of dust, you'll need to change your filter more often than someone who doesn't have pets and lives in a clean environment. In general, it's a good idea to change your filter at least once every three months, but you may need to do it more often if you have special circumstances.

Type of Furnace

Finally, the type of furnace you have will also play a role in which filter you choose. You can use almost any type of filter if you have a standard furnace. However, if you have an electric furnace, you'll need to use a special electrostatic filter. These filters are more expensive than other types of filters, but they're necessary to protect your furnace from damage.

Conclusion:

When it comes time to purchase a new furnace filter, there are several factors you'll want to keep in mind in order to get the best possible product for your needs. Be sure to consider size, efficiency rating, and cost before making your final decision.
