Why Filters for Intertherm Furnace are Necessary

As a homeowner who has experienced the benefits of using filters for my Intertherm furnace, I can confidently say that they are a necessary component of any heating system. Here are a few reasons why:

This results in cleaner and fresher air, making it easier for you and your family to breathe. This is especially important for individuals with allergies or respiratory issues.

2. Increased Efficiency: When dust and debris accumulate in your furnace, it can hinder its performance and efficiency. Regularly replacing the filters allows air to flow freely, allowing your furnace to work more efficiently and effectively.

3. Extended Lifespan: A clogged or dirty furnace can put strain on its components, causing them to wear out faster. By using filters, you can prevent this from happening and extend the lifespan of your Intertherm furnace.

My Buying Guide on Filters For Intertherm Furnace

As a homeowner with an Intertherm furnace, I understand the importance of having a high-quality furnace filter. Not only does it improve the efficiency and longevity of my furnace, but it also helps to maintain good air quality in my home. After doing extensive research and trying out different filters, I have compiled a buying guide for others who are looking to purchase filters for their Intertherm furnace.

Determine the Appropriate Size

The first step in buying a filter for your Intertherm furnace is to determine the size you need. Most furnaces have their filter size listed on the side of the filter cabinet or in the owner’s manual. It is essential to get the correct size as using an ill-fitting filter can cause airflow issues and reduce its effectiveness.

Choose the Right Type of Filter

Intertherm furnaces are compatible with different types of filters, including fiberglass, pleated, electrostatic, and HEPA filters. Each type has its pros and cons, so it’s crucial to consider your specific needs before making a decision.

  • Fiberglass filters are inexpensive but only offer basic filtration and need to be replaced frequently.
  • Pleated filters have more surface area for trapping particles and can last up to three months.
  • Electrostatic filters use static electricity to attract particles and are washable for multiple uses but may be less effective at capturing smaller particles.
  • HEPA filters offer the highest level of filtration but may require modifications to fit into an Intertherm furnace.

Consider MERV Rating

The Minimum Efficiency Reporting Value (MERV) rating is used to measure how well a filter removes particles from the air. The higher the MERV rating, the better its filtration capabilities. For most residential homes, a MERV rating between 8-11 is sufficient. However, if you have allergies or respiratory issues, you may want to consider a higher MERV rating.

Look for Quality Brands

When purchasing a filter for your Intertherm furnace, it’s essential to choose a reputable brand that produces high-quality products. Some popular brands that offer compatible filters include Nordic Pure, Filtrete, Honeywell, and Carrier/Bryant/Payne.

Budget Considerations

The cost of furnace filters can vary depending on their type and brand. While it may be tempting to opt for cheaper options, keep in mind that they may not be as effective or long-lasting as more expensive ones. Consider your budget while also prioritizing quality when making your decision.

Regular Replacement Schedule

To ensure optimal performance from your Intertherm furnace and maintain good air quality in your home, it’s essential to replace your filter regularly. The frequency will depend on factors such as type of filter used and household conditions (e.g., pets, smokers). Typically, pleated filters should be replaced every three months while washable electrostatic filters can last up to eight years with proper maintenance.

In conclusion,‘s guide has covered some crucial factors you need to consider when purchasing filters for your Intertherm Furnace – determining size requirements, choosing appropriate types based on needs/conditions/price considerations/MERV ratings/brands/live time cycles etc.. By following this guide and considering all these factors carefully before making your purchase decision – you can ensure that you get high-quality filters that will effectively improve the performance of your Intertherm furnace while maintaining good indoor air quality in your home.
