Flanders Pre Pleat 40 LPD filters are one of the best selling filters we carry. Originally designed with commercial applications in mind it's now our favorite choice for residential systems as well. This filter doesn't have all the fancy packaging or catchy name, it just does what it should...protect your system and clean your air. This filter has a very low pressure drop (LPD), this means the filter captures a lot of stuff you cant see with the naked eye and at the same time it isn't restrictive. Restrictive means more energy use, thus more money and strain on your system.
Forget all the fancy packaging and marketing, go with a filter you can trust. The inherent strength of the filter allows for easy change out as it will not collapse, warp, or bend in normal service. Flanders Precisionaire is a US company started in 1950. They are foremost in air filtration.
