Why Filters For Intertherm Furnace are Necessary

As a homeowner who has owned an Intertherm furnace for several years, I can confidently say that filters are absolutely necessary for this type of furnace. Here are a few reasons why:

1. Improved Air Quality: The main purpose of filters in a furnace is to trap dust, dirt, and other airborne particles before they circulate throughout your home. Without a filter, these particles can aggravate allergies and respiratory issues, making the air inside your home less healthy.

2. Protection for Your Furnace: A dirty filter can restrict airflow and cause your furnace to work harder to distribute heat. This can lead to increased wear and tear on the furnace’s components, resulting in more frequent breakdowns and costly repairs.

3. Energy Efficiency: When your furnace has to work harder due to a clogged or dirty filter, it also uses more energy. This means higher utility bills for you. By regularly replacing or cleaning the filter, you can ensure that your furnace is operating at its most efficient level.

4. Cost Savings: Investing in filters for your Intertherm furnace may seem like an additional expense, but it can actually save you money in the long run. By preventing damage to your furnace

My Buying Guide on Filters For Intertherm Furnace

Hello there! I recently went through the process of buying filters for my Intertherm furnace and I must say, it was quite overwhelming. With so many options available in the market, it can be challenging to choose the right one. But don’t worry, I have put together this buying guide to help you make an informed decision. So let’s get started!

1. Know Your Furnace’s Filter Size

The first step in purchasing filters for your Intertherm furnace is to know its filter size. This information can usually be found in your furnace’s manual or by checking the existing filter. The size is usually indicated in inches and will be something like 16x20x1 or 20x25x4. Make sure to measure correctly as using the wrong size filter can damage your furnace.

2. Choose the Right Type of Filter

There are various types of filters available for Intertherm furnaces, including disposable fiberglass, pleated, electrostatic, and high-efficiency filters. Disposable fiberglass filters are the most basic and economical option but have a lower filtration efficiency. Pleated filters have a higher efficiency and can help improve indoor air quality. Electrostatic filters use static electricity to trap dust and other particles, making them a good option for those with allergies or asthma. High-efficiency filters have the best filtration efficiency but come at a higher cost.

3. Consider MERV Rating

MERV (Minimum Efficiency Reporting Value) rating is a scale that rates the effectiveness of air filters in removing particles from the air. The higher the MERV rating, the more efficient the filter is at capturing smaller particles such as pollen, pet dander, and mold spores. However, it is essential to note that high-efficiency filters with a MERV rating above 12 may restrict airflow and put strain on your furnace.

4. Check Filter Lifespan

Another important factor to consider is how long the filter will last before needing to be replaced. This information can typically be found on the label or packaging of the filter and is usually measured in months or hours of usage.

5: Compare Prices

Filters for Intertherm furnaces come at different price points depending on their type and features. It is always a good idea to compare prices from different retailers or online stores before making a purchase.

6: Look for Deals and Discounts

Keep an eye out for deals and discounts offered by retailers or manufacturers on filters for Intertherm furnaces. Buying in bulk can also save you some money in the long run.

7: Read Reviews

Lastly, before making a final decision, read reviews from other customers who have used the same type of filter for their Intertherm furnace. This will give you an idea of its performance and durability.

I hope this guide has helped you understand what to look for when buying filters for your Intertherm furnace.
