AirGuard Air Filters was part of CLARCOR Air Filtration Products (CLC Air) which was founded in 1964 and manufactures HVAC filtration products under the AirGuard brand name. In early 2017 CLARCOR was purchased by Parker Hannifin.
AirGuard filters come in many sizes. As with all furnace, HVAC and AC filters they are interchangeable with any brand as long as you replace with the same filter size. While we don't carry the AirGuard Air Filter brand, we have a large selection of replacement air filters in the same standard sizes that perform just as well if not better. Plus you have several efficiency rating options and can save money with many of the filter options we carry. We only work with leading manufacturers in the indoor air filtration industry for both commercial and residential systems.
