Pleated filters are some of the most popular filters on the market today! They are made from media that is folded into pleats which increases the entire surface area of the filter making it more efficient. This style of filter can help to eliminate large allergens like pollen and mold. We recommend the use of pleated filters due to their affordable pricing and wide array of options.
