Furnace air filters not only just keep the air in your home clean, but also play an essential role in determining energy costs. So, it’s always recommended to replace your air conditioner and furnace filter every 30 to 60 days. However, Merv Filters LLC’s filters can last for 90 days, you may wish to change your filters earlier if you have pets, live with a smoker or allergy sufferer. We offer the most comprehensive coverage of standard size filters for homeowners. If you don’t find the one that meets your requirements, order custom size filter online starting as low as $4.99.
Our 18x24x2 MERV 11 filter is crafted using synthetic media which is unaffected by the moisture and resistant to various harmful chemicals. Our pleated filter media incorporate a 100% synthetic media that is coated to a heavy-duty, galvanized metal which stabilizes the media during system operation. Our advanced pleat technology ensures proper dust-loading and will not promote the growth of bacteria or fungi. Our MERV 11 filters are ideal to use for standard or superior residential and commercial application.
Important Note: When you look for air filters, make sure you compare their nominal size and actual size. The nominal size is typically printed on the cardboard edge of your air filter, which is a bit greater than the actual size. For example, if the nominal size of the filter is 18x24x2, the actual size will be 17.5×23.5×1.75
