Home Heating: Three Types Of Air Filters For Your Furnace System

Posted on: 20 April 2015

It is no secret that the air filter in your home cleans the air. Although it is often unseen, it is constantly working to remove microscopic dust and allergen particles to give you fresh, clean air. If your home seems stuffy or you find yourself sneezing indoors, it's likely that you need to replace your air filter.

Choosing the right air filter may seem easy, but when faced with all of the different options, it can quickly become difficult and tiresome. So what type of air filter do you choose? Although the answer will vary depending on your needs, you can start by learning about the different types—and what they do.

Here are three popular air filters for home furnace systems:

1. Pleated Air Filters

As the name suggests, a pleated air filter has several small pleats that filter the air. They work well to remove standard air pollutants such as dust mites, dust, mold, bacteria, and pet dander. They also remove pollen, which can significantly help those with allergies or asthma breathe better.

Unfortunately, a pleated filter only lasts about 90-days, so it needs to be replaced every three months. In between changings, the filter does need to be cleaned; usually monthly cleanings are required, but more frequent cleanings may be needed depending on your area and usage.

2. Washable Air Filters

If you are looking to make your home "green," a washable filter may be ideal for you. As you might expect, these filters are affordable and easy to wash. All it requires is water, which can come from your kitchen sink or garden hose.

Washable filters are typically made from animal hair or Polypropylene. Both materials work efficiently to trap standard air pollutants, including pet dander and dust; however, these filters are not as effective as others, so very small particles such as pollen may slip through.

While washable filters are energy efficient, they do not last forever—regardless of what the name implies. Like all filters, these need to be changed every three to six months depending on your usage.

3. Electronic Air Filters

If you suffer from severe allergies or respiratory problems, an electronic air filter should be your number one choice. Electronic filters use an electrical charge to disrupt air pollutants and trap them in place. These filters are very effective and can remove up to 99-percent of all particles in the air, such as pet dander and smoke.

Electronic filters do need to be cleaned and replaced, with cleanings every two to four weeks and replacements every two to twelve months. Again, how long your filter will last depends on your location, usage, and lifestyle.

If you are in the market for a new air filter for your furnace, consider these three options. If these options do not appeal to you, talk to your home heating repairman for more information about a home assessment to determine what type of air filter is best for you.

Expanding Families Means Expanding Homes: Addition Building 101

When my wife and I found out we were expecting a baby, I knew that our small starter home wasn't going to be big enough for us to raise a family. We loved the house and the neighborhood though, so we didn't want to move. That's when I decided to just build an addition. From planning to construction, the process was kind of intimidating. I didn't know what to expect along the way, and that made it more difficult. I created this site to detail our experience with the construction of the addition. I hope it helps you to prepare for your next home construction project.
