When it comes to furnace air filters, there are two main types to choose from: pleated media and disposable filters. Pleated media filters are more efficient, but they come with a higher price tag. Disposable filters are more affordable initially, but they require more frequent replacement. To make the most cost-effective choice in the long run, it's important to understand the differences between these two types of filters and how they can affect your home's air quality.
Pleated media filters are designed to capture smaller particles than disposable filters, making them more effective at improving indoor air quality. Despite their slightly higher cost, these filters need to be replaced less often, which could be more cost-effective in the long term than fiberglass filters. When installing a pleated filter, make sure to check the correct dimensions and direction of air flow as indicated on the filter frame or in the equipment's owner's manual. Disposable filters are great when it comes to trapping smaller particles, and they're also usually more affordable (at first). The type of disposable filter you choose will also be an important decision to ensure you have the best filter for your air conditioning system.
Most home improvement stores sell air conditioning filters ranging from MERV 1 to MERV 13, although some models can reach up to MERV 16. If you have an HVAC system with filters inside the return air ducts spread over several rooms of the house, we recommend looking for qualified filters such as the Nordic Pure MERV 12, which often costs less than other options. In real conditions, since the air in the house is constantly recirculated through the ducts and passes through the filters each time, the cumulative effect of the filters increases. This means that even a MERV 1 filter can improve your home's indoor air quality by trapping dust, pollen, and other small particles. You'll most likely need to replace your air conditioning filter at least three times a year, so it's important to choose one that is both effective and affordable. When it comes to choosing an effective filter for your home, look for one with a Minimum Efficiency Reporting Value (MERV).
This rating system measures how effectively a filter removes particles from the air. For most residential systems of forced air, HEPA filters are not recommended due to their tight filtration which can restrict airflow. In conclusion, when selecting an air filter for your furnace or HVAC system, consider both initial cost and long-term cost-effectiveness. Pleated media filters may be more expensive upfront but require less frequent replacement than disposable filters. To ensure you have the best filter for your home's needs, look for one with a high MERV rating.
