What You Need To Know About AC Filters: A Guide For Homeowners

If you have an air conditioning unit in your home, it is important to know that the AC filters need to be regularly changed. In this article, we will explain why and provide you with some useful tips to help you keep your AC filter in top shape. Find out more about what you need to know about AC filters and how to care for them here!

What is an Air Conditioner Filter?

An air conditioner filter helps to remove airborne contaminants from the air passing through your AC system. These filters typically consist of a pleated paper or fiberglass material that can trap particles as small as 0.3 microns in size.

While most homeowners know that it’s important to change their AC filters regularly, they may not be aware of how often these changes should occur. Depending on the type of filter you have and the level of contaminants in your home, you may need to change your AC filter every 1-3 months.

If you have pets or members of your household suffer from allergies, it’s especially important to check and change your AC filter regularly. Allowing dirt and dust to build up on your filter can lead to reduced air flow and decreased efficiency from your air conditioner. In addition, the 14x20x1 filters help to reduce the amount of dust, pollen, and other allergens in the air you breathe. 

If you’re not sure how often to change your AC filter, consult your owner’s manual or ask a professional for guidance.4 Taking these simple steps can help ensure that your AC system is running efficiently and keeping your home free of harmful airborne contaminants.

Different Types of AC Filters

Air conditioner filters come in a variety of shapes, sizes, and materials. The most common type of AC filter is the pleated paper filter. These filters are made of paper that is pleated to increase surface area and capture more dust particles.

Pleated paper filters are available in a range of MERV ratings, which indicate how effective they are at capturing different types of particles. A higher MERV rating means better filtration, but also results in increased air resistance, which can reduce the efficiency of your AC unit.

Another type of AC filter is the fiberglass filter. These filters are made from fibers that are woven together to create a tight mesh. Fiberglass filters have a lower MERV rating than pleated paper filters, but they do not restrict airflow as much.

The last type of AC filter is the washable electrostatic filter. These filters use an electrically charged grid to attract and capture dust particles. Washable electrostatic filters need to be cleaned regularly to maintain their effectiveness, but they can be reused indefinitely.

Benefits of Changing Your AC Filters Regularly

One of the most important things you can do to maintain your AC unit is to change the filter regularly. A clogged or dirty filter can restrict air flow, causing your AC unit to work harder and less efficiently. In addition, a dirty filter can allow dirt and dust to build up on the coils, which can eventually lead to system failure.

Changing your AC filter regularly is one of the easiest and most effective ways to extend the life of your AC unit and keep it running at peak performance. We recommend changing your filter every 1-3 months, depending on the type of filter you have and the level of use your AC unit gets.

There are many benefits to changing your AC filters regularly:

  1. extends the life of your AC unit
  2. keeps your AC unit running at peak performance
  3. lowers energy bills by making your AC unit more efficient
  4. improves indoor air quality by trapping dirt, dust, pollen, and other airborne particles

How Often Should You Change Your AC Filter?

If you have a central air conditioner, you know that one of the most important maintenance tasks is to regularly change the AC filter. But how often should you change your AC filter?

The answer depends on a few factors, including the type of filter you have and the amount of use your AC gets. For most homeowners, changing the AC filter every 3 months is sufficient. However, if you have pets or live in a dusty area, you may need to change it more often.

There are a few easy ways to tell when it’s time to change your AC filter. First, check the manufacturer’s recommendation. Second, take a look at the filter itself – if it’s visibly dirty, it needs to be changed. Finally, pay attention to how your AC is running – if it seems to be working harder than usual or isn’t cooling as well as it used to, chances are good that the filter is dirty and needs to be replaced.

Changing your AC filter is easy and only takes a few minutes. Just be sure to buy the correct size for your unit and follow the manufacturer’s instructions for installation.

Tips for Choosing the Right Filter

If you’re like most people, you probably don’t give your air conditioner’s filter much thought. However, the filter plays a crucial role in keeping your AC unit running smoothly and efficiently. Here are a few tips to help you choose the right filter for your AC unit:

  1. Check the manufacturer’s recommendations. The first step is to check your AC unit’s manual or manufacturer’s website to see what type of filter is recommended.
  2. Consider your home’s environment. If you live in an area with a lot of dust or pollen, you’ll need a more powerful filter to keep your AC unit clean.
  3. Choose the right size. Filters come in a variety of sizes, so it’s important to choose one that will fit your AC unit properly.
  4. Compare prices and reviews. Once you’ve narrowed down your options, it’s time to compare prices and read reviews to find the best value for your money.

Cost and Installation of a New Filter

If your old AC filter is shot and you’re in the market for a replacement, this guide is for you. We’ll cover the cost and installation of a new filter, as well as some tips on choosing the right one for your home.

The cost of a new AC filter will vary depending on the size and type of filter you need. A standard pleated air filter should cost between $5 and $20, while a higher-quality HEPA air filter can cost up to $100.Installation costs will also vary depending on the type of filter you choose. A standard pleated air filter can be installed by a homeowner with basic handyman skills, while a HEPA air filter may require professional installation.

When choosing a new AC filter, it’s important to consider the specific needs of your home. If you have allergies or asthma, for example, you’ll want to choose a high-quality HEPA air filter that will trap smaller particles and allergens. Alternatively, if your main concern is saving money on energy bills, you may want to opt for a cheaper pleated air filter. Ultimately, the best AC filter for your home is the one that meets your specific needs and budget.
