Measuring 18 inches wide by 18 inches tall by 1 inch deep, it delivers 300 FPM airflow with an initial resistance of 0.1 inches WC and a final resistance of 0.5 inches WC. The filter uses a heavy-duty media supported by a rigid one-piece craft-board frame that holds its shape under sustained airflow conditions. A metal grid on the air-leaving side reinforces the media and prevents blowout at higher velocities. HVAC technicians and facilities maintenance personnel install this filter in standard 18x18x1 filter housings and air handlers. It carries an Energy Star rating and is manufactured in the USA.\u003c\/p\u003e\u003cp\u003eThe PTA_18X18X1 is suited for a wide range of applications including residential forced-air furnaces and air handlers, light commercial rooftop units, and industrial air-handling equipment. With a temperature rating of 180 degrees F, it holds up in equipment that sees elevated operating conditions. The 2.25 square foot media area and 300 FPM flow rate make it appropriate for standard residential and commercial filter tracks where a 1-inch disposable panel filter is specified. The filter meets UL 900, HARDI, and NAFA applicable standards, making it suitable for installations where third-party certification is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRigid one-piece craft-board frame resists collapse and moisture deformation\u003c\/li\u003e\n\u003cli\u003eHeavy-duty media with metal support grid on the air-leaving side prevents blowout\u003c\/li\u003e\n\u003cli\u003eRated for airflow up to 300 FPM with 0.1 inches WC initial resistance\u003c\/li\u003e\n\u003cli\u003eTemperature rated to 180 degrees F for use in high-heat applications\u003c\/li\u003e\n\u003cli\u003eMeets UL 900, HARDI, and NAFA standards\u003c\/li\u003e\n\u003cli\u003eEnergy Star rated and manufactured in the USA\u003c\/li\u003e\n\u003cli\u003eDisposable design for straightforward changeout with no cleaning required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or maintenance-stock disposable panel filter for residential, commercial, and industrial HVAC systems requiring an 18x18x1 inch filter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed HVAC technician or qualified maintenance personnel should power down the air handler or furnace at the disconnect before servicing the filter rack.
