Made of cotton or polyester, pleated filters are one of the most popular and efficient filter options. Its effectiveness, however, varies according to the folds per foot. For a pleated filter to have an efficiency rating of 10 to 13, it must have at least 18 folds per foot. Air filters play an important role in our indoor environment, protecting occupants and equipment from poor air quality, dust, particles and pollutants.
They also protect HVAC systems from unnecessary maintenance and malfunction. When it comes to air filters, the most cost-effective option is not always the cheapest. Many people only consider the starting price when buying a filter, but the real cost is the long-term expense of using it. Here's a look at some of the most common high-efficiency air filters, their advantages and applications, as well as how to determine their lifecycle for greater efficiency and cost savings.
The Filtrete Micro Allergen Defense filter is without a doubt the best there is. Filtrete is one of the most popular filter brands for a good reason. The Filtrete 10x20x1 AC oven air filter can capture most large particles in the air and is compatible with most HVAC systems. It comes in an affordable six-pack for whole-home protection.
The industry standard for measuring air filter efficiency is the Minimum Efficiency Reporting Value (MERV) system. Spending a little more on finding the best air filter for your HVAC system can save you time before needing a change. However, these filters usually cost significantly more than basic fiberglass filters. Fiberglass, polyester, washable, pleated and electrostatic filters all offer different air filtering capabilities.
The Home Depot also offers a full range of air cleaner accessories to keep your system running at peak performance. Medium-efficiency MERV filters such as the Nordic Pure MERV 12 can greatly reduce airborne dust, mold spores, pollen and even smoke, which can help alleviate respiratory ailments according to an NIH review. Pocket filters are generally used as final filters in commercial applications or as pre-filters in pharmaceutical or hospital applications. Replacing a filter takes a few seconds while cleaning a reusable filter and letting it dry can take much longer. In conclusion, when it comes to air filters, it's important to consider more than just the starting price. Investing in high-efficiency filters can save you time and money in the long run while providing better protection for your home or business.
