As an HVAC expert, I have seen firsthand the impact that furnace filters can have on the performance of an oven. Many homeowners may not realize the importance of these filters, but they play a crucial role in keeping the air in your home clean and free of contaminants. However, not all furnace filters are created equal. In fact, there is a common misconception among some HVAC professionals that cheaper filters are better.
But as I will explain, investing in better quality filters can make a significant difference in the efficiency and effectiveness of your HVAC system. First, let's clarify the difference between return air filters and furnace filters. Both of these components serve the same purpose - to clean the air as it circulates through your home. This is an essential process that occurs whenever your HVAC system is running. In most cases, a central air system will use two separate filters to properly filter out unwanted particles, allergens, bacteria, and more. The key to understanding the effectiveness of furnace filters lies in their ability to capture debris.
Better quality filters have a larger surface area, allowing them to trap more particles with their relatively porous filter material. In fact, they can capture about four times more filter material than a standard 1-inch filter. This means that they can effectively remove more contaminants from the air in your home. It's worth noting that the filtration process is the same for both air filters and furnace filters. This means that some homes may use a single filtration system or type of air filter for both heated and cooled air.
However, it's important to keep in mind that no filter manufacturer can predict how long their filters will last because they do not know the specific dust conditions in your home. Therefore, it's essential to check your filters frequently and replace them as needed. When it comes to purchasing replacement filters, you may be overwhelmed by the variety of options available. However, for most homes, a filter with a rating of at least MERV 11 will suffice. This is the rating where filters begin to trap most particles the size of common allergens.
If you are unsure of the size of your current filter, you can easily find this information printed on the filter frame. Simply take note or even take a picture to ensure that you purchase the correct size. At Filterbuy, we offer a wide selection of high-quality furnace filters that can be conveniently delivered right to your doorstep. It's recommended to replace your filter every three to 12 months, depending on its size and usage. As your filter is used over time, its cumulative effect will increase, making it even more effective at removing contaminants from the air in your home. In my experience, I have found that many homeowners are not aware of the differences between heating filters and air conditioning filters.
This is especially important for older homes or homes with special heating and cooling needs. For example, in New England where winter weather is more prominent, different filters may be required to effectively filter out contaminants. One common issue that can arise from using a low-quality or clogged filter is decreased efficiency in both your boiler and air conditioner. When a filter becomes clogged, it causes your HVAC system to work harder and less efficiently. This can lead to higher energy bills and potential damage to your system.
