Filterbuy 14x25x1 Air Filter MERV 11 Allergen Defense 4-Pack, Pleated HVAC AC Furnace Air Filters Replacement Actual Size: 13.50 x 24.50 x 0.75 Inches

The Filterbuy 14x25x1 Air Filter MERV 11 promises to provide excellent filtration for removing pollen and mold spores from your HVAC AC furnace. Based on customer reviews, these air filters are effective and do not compromise on adherence to the specified MERV 11 rating. The product is a 4-pack of pleated filters with an actual size of 13.50 x 24.50 x 0.75 inches. The product information and technical details section seems misleading since it states "minimum efficiency reporting values (merv) 8" in some places while elsewhere, it states MERV 11. However, customers confirm that they received MERV 11 filters as indicated on the filter packaging and wrapping. The filters are also designed with an arrow printed on the frame to indicate the flow direction. There have been complaints from some customers regarding the filters being smaller than their HVAC AC furnace, leading to issues with fitting properly into the filter housing. Still, many customers report that these filters were effective and of good quality.
