Effective and well made
Does the job well at a fair price. Would like a couple more size options, but the performance is excellent.
Airguard Envirocare HV2-AG is an Altair-equivalent high-efficiency pocket filter compatible with Altair System 2, Altair Neptune and Altair Vega systems, providing reliable filtration for gas turbine intake applications.


The HV2-AG is an OEM-equivalent high-efficiency pocket filter for gas turbine air intake systems, designed for offshore and coastal environments with salt aerosols, fine particles and humidity. Its staged pocket design provides high dust-holding capacity, controlled pressure loss and cleanable performance, with standard and non-standard sizes available as an Altair replacement filter.
Each HV2-AG pocket uses three filtration stages: a protective filter net, a high-loft pre-filter mat for dust loading, and a needlefelt layer for final filtration. It uses 100% silicone-free synthetic media and bonded polyester, with a 22 mm stainless-steel frame, clips and factory-fitted seals available for demanding gas turbine intake applications.
