Straightforward specification
Sent over our old filter details and got a like-for-like match back the same day. Fitted first time with no modifications needed.
Airguard Envirocare’s HVX-AG is an OEM-equivalent high-efficiency pocket filter compatible with Altair System 2, Altair Neptune and Altair Vega, providing a practical replacement option for demanding gas turbine intake applications.


The HVX-AG was designed for gas turbine air-intake systems, providing high-efficiency filtration for offshore and coastal environments. It is engineered for high-velocity operation in wet and dry conditions, helping manage humidity and salt spray. The HVX-AG is an OEM-equivalent replacement for Altair-specified systems, offering comparable efficiency, dust-holding capacity and construction quality to Parker Hannifin alternatives, with a lower unit cost.
The four pockets use a two-stage design, combining high-loft media for coarse dust with 100% polypropylene media for high-efficiency filtration. This provides low initial resistance, high dust-holding capacity and stable performance at high airflow, with standard and custom sizes available.

We order these regularly and the quality doesn't drift — same media, same fit, same performance every time.
Does the job well at a fair price. Would like a couple more size options, but the performance is excellent.
Great filtration and good value for money. Delivery was prompt and the fit was accurate for our housings.
Matched our OEM specification perfectly and was delivered within 24 hours. Excellent airflow and build quality.
Dust holding capacity is noticeably better than what we were using, so we're getting longer intervals between changes.
