Why Filters for Intertherm Furnace are Necessary

I have been using an Intertherm furnace for several years now, and one thing that I have learned is the importance of regularly changing the filters. At first, I didn’t think much of it and would often let months go by without replacing the filter. However, as time went on, I noticed that my furnace was not performing as efficiently as it used to. That’s when I realized the significance of filters for an Intertherm furnace.

One of the main reasons why filters are necessary for an Intertherm furnace is to improve indoor air quality. The filter’s primary function is to trap dust, dirt, and other particles from circulating in your home’s air. Without a clean filter, these contaminants can enter your living space and cause respiratory issues or worsen existing allergies.

Moreover, dirty filters can also significantly affect your furnace’s efficiency and lifespan. When a filter becomes clogged with debris, it restricts airflow and forces the furnace to work harder to circulate warm air throughout your home. This extra strain can lead to premature wear and tear on the furnace components, resulting in costly repairs or even a complete breakdown.

By regularly changing the filters on your Intertherm furnace,

My Buying Guide on ‘Filters For Intertherm Furnace’

As a homeowner who has been using an Intertherm furnace for several years, I understand the importance of having the right filters for optimal performance and longevity of my furnace. With so many options available in the market, choosing the right filter can be overwhelming. Therefore, I have put together this buying guide to help you make an informed decision when purchasing filters for your Intertherm furnace.

Understanding Intertherm Furnace Filters

Before delving into the different types of filters, it is essential to understand the purpose of a filter in your Intertherm furnace. The primary function of a filter is to trap dust, debris, and other contaminants from entering your furnace’s heat exchanger and other sensitive components. This not only helps in maintaining good indoor air quality but also prevents damage to your furnace.

Types of Filters

There are three main types of filters that are compatible with Intertherm furnaces: disposable, washable, and electronic filters.

1. Disposable Filters: These are the most common type of filters used in Intertherm furnaces. They are made from pleated paper or fiberglass and come in various sizes and MERV ratings (Minimum Efficiency Reporting Value). The higher the MERV rating, the more efficient the filter is at trapping small particles. However, it is essential to note that high MERV rated filters may restrict airflow and cause strain on your furnace’s blower motor.

2. Washable Filters: As the name suggests, these filters can be washed and reused multiple times. They are made from materials like foam or mesh and have a lower MERV rating compared to disposable filters. While they may seem like a cost-effective option in the long run, they require regular maintenance to ensure proper functioning.

3. Electronic Filters: These advanced filters use electricity to charge particles as they pass through them, causing them to stick on opposite-charged plates within the filter. They have a high MERV rating and offer superior air filtration; however, they come at a higher cost compared to disposable or washable filters.

Choosing the Right Size

It is crucial to choose a filter that fits your Intertherm furnace perfectly. Most manufacturers provide sizing information on their websites or packaging labels; however, if you are unsure about which size will fit your furnace, it is best to consult with an HVAC professional.

Frequency of Replacement

The frequency at which you need to replace your filter depends on several factors such as usage, indoor air quality, presence of pets or smokers in your home, etc. It is recommended to check your filter every 30 days and replace it when it appears dirty or clogged. In general, disposable filters should be replaced every 1-3 months while washable ones should be cleaned every 1-2 months.

Budget Considerations

When purchasing filters for your Intertherm furnace, it is essential to strike a balance between cost-effectiveness and efficiency. While cheaper disposable filters may seem like a good deal initially, they may need frequent replacements that can add up over time. On the other hand, electronic filters may have higher upfront costs but require minimal maintenance and replacements.

In conclusion,‘s buying guide on ‘Filters For Intertherm Furnace’ suggests considering factors such as type of filter (disposable/washable/electronic), size compatibility with your furnace model,, frequency of replacement,, and budget considerations before making a purchase decision. Regularly replacing/cleaning your filter not only ensures efficient functioning of your furnace but also contributes towards maintaining good indoor air quality for you and your family’s well-being.
