How to replace an air filter

It’s important to change your air filter regularly to improve air quality and prevent dirt, dust, and other airborne particles from building up inside your HVAC system. A clogged filter or dirty air filter can cause a host of problems inside your home and central air system HVAC unit, so it is important to install a new filter regularly, or clean the reusable AC filter you use with your furnace unit or cooling system.

In this blog post, Williams Comfort Air shows you how to replace home air filter units in just a few easy steps. Also, learn hoe to find the right filter when it’s time to purchase or order new air filters.

Finding the Right Size Air Filters

Many homeowners don’t realize how important it is to have the right size furnace filter. Not only does a properly sized filter help your furnace run more efficiently, but it can also improve indoor air quality and help to prolong the life of your furnace. So how do you know what size filter you need? The first step is to take a look at your furnace. Most furnaces will have a sticker somewhere that indicates the recommended size for the filter.

If you can’t find this information, or if you are unsure, take a look in your furnace’s owners manual. You can also find this information by using a measuring tape and the existing air filter. To measure the cardboard frame of the existing furnace filter, start by removing the old filter from the furnace. Next, use a tape measure to determine the length, width and depth of the frame. With these dimensions in hand, you’ll be able to find a replacement filter that is the perfect size for your furnace. By taking a few minutes to measure the frame, you can help ensure that your furnace continues to run smoothly for years to come.

Selecting a New Air Filter

Once you’ve determined the size you need, the next step is to choose the type of filter. But with all the different types and sizes of filters available, how do you know which one is right for your furnace? Here are a few things to keep in mind when choosing a furnace filter:

Consider the type of filter you want. There are disposable filters made of fiberglass or pleated paper, as well as reusable filters made of metal or plastic. Each type has its own advantages and disadvantages, so choose the one that best fits your needs. For example, some filters are designed to capture smaller particles, while others are better at removing odors. Ultimately, the best type of filter for your home will depend on your specific needs. By taking the time to find the right size and type of furnace filter, you can help keep your home comfortable and breathable all winter long.

Fiberglass Air Filters

Air filters are an important part of any HVAC system, and there are a variety of different types to choose from. Fiberglass air filters are a popular option because they are relatively inexpensive and easy to find. However, fiberglass air filters can also be less effective than other types of filters, such as HEPA filters. This is because fiberglass filters are not able to trap small particles as effectively. As a result, they may need to be replaced more often. Additionally, some people find that fiberglass air filters cause irritation or allergic reactions. If you have concerns about using a fiberglass air filter, talk to your doctor or an HVAC specialist.

Pleated Air Filters

Pleated air filters are a type of HVAC filter that can be used in residential and commercial settings. They are often used in place of disposable fiberglass filters, as they have a longer lifespan and are more effective at trapping small particles. When shopping for a pleated air filter, it is important to consider the MERV rating. This rating system indicates the filter’s ability to capture different sized particles, with a higher number meaning better filtration. Pleated air filters are available in a range of MERV ratings, so it is important to choose one that is appropriate for your needs. In general, higher-rated filters will provide better protection against allergens and other airborne contaminants.

Washable Air Filters

Air filters are an important part of any HVAC system, as they help to remove contaminants from the air and improve indoor air quality. However, not all air filters are created equal. Some filters are designed to be disposable, while others can be washed and reused. Washable air filters offer a number of advantages over their disposable counterparts. For one, they are more environmentally friendly, as they can be reused multiple times. Additionally, washable filters tend to be more durable and last longer than disposable filters. If you’re looking for an air filter that will provide long-lasting performance and improve your indoor air quality, a washable air filter is a great option.

MERV Ratings

Finally, pay attention to the MERV rating. This stands for “Minimum Efficiency Reporting Value” and it measures how well a filter can remove particles from the air. The higher the MERV rating, the more efficient the filter will be. However, keep in mind that high-efficiency filters can also restrict air flow, so if your furnace is already having trouble getting enough airflow, you may want to choose a lower-rated filter. With these tips in mind, you should be able to find the perfect furnace filter for your home.

Most people are familiar with the term MERV rating, but not everyone knows that there is such a thing as too high of a MERV rating. When it comes to residential HVAC systems, the highest MERV rating you want to choose for a new air filter is 13. This is because some high efficiency air filters can actually restrict air movement through the furnace or air handler, leading to energy efficiency issues and causing damage to the unit. Only use filters like HEPA filters if your HVAC equipment is specifically designed to do so. Not sure what MERV rating you need? Just ask your HVAC professional during your annual tune up or when you’re considering a new air filter.

How to Replace Home Air Filter Units

Replacing a furnace filter is a relatively simple task that can be done in just a few minutes. Most filters are located in the return air duct or near the blower motor.

  1. Turn off the furnace or central air handler before you replace the filter to prevent any dust and mess in the surrounding area.
  2. Once you have located the filter slot, simply remove the existing air filter from the HVAC system and dispose of it.
  3. Insert the new filter into the filter compartment of the furnace or air handler cabinet according to the directional arrows printed on the cardboard frame.
  4. If your unit uses an accordion-style filter that attaches to a removable frame, you need to remove the old filter from the frame and attach the new filter in its place.
  5. Make sure the filter frame fits snugly into the heating and cooling system filter compartment, then turn the HVAC system back on.

Be sure to check your owner’s manual for specific instructions on how to replace your particular furnace filter. By taking this simple step, you can help to keep your furnace running efficiently and help prevent costly repairs down the road.

A reusable filter requires a bit more maintenance than a standard disposable filter used in many air conditioning system and heating system units. Here’s a quick guide to washing your air filter:

  1. Start by removing the old air filter from your furnace.
  2. Next, vacuum the area around the furnace to remove any dust or dirt that has accumulated there.
  3. Now you’re ready to wash the air filter itself. Wash the reusable filter with warm soapy water, rinse it, and dry thoroughly before reinstalling.
  4. Once the filter is clean and dry, you can install it in your furnace and enjoy the benefits of cleaner air!
