The Riga-Carb/PH rigid filter is suitable for virtually any IAQ application where high adsorbency is required, and where space and pressure drop limitations exist, says the manufacturer. The product incorporates a general-purpose-duty carbon suspended in a fibrous media, using a patented technology that yields “maximum adsorbency, superior service life, and negligible dusting,” says the manufacturer. The 12-in., deep-pleated filter with peripheral header may be installed in filter-holding frames for built-up banks, in side-access housings, or in existing track-type housings with oem units.
