The disposable mini-pleat Eco Cell Filter is fabricated using Irema Irelands Micro Media (Pleat) made from 100% polypropylene meltblown that meets all standards for filtration efficiency. Our mini-pleat manufacturing technology ensures that each pleated pack provides the maximum filtration surface area fixed in place by hotmelt, providing low pressure drop due to laminar air-flow through the pack. The mini-pleated media pack is housed in a robust plastic frame.
