The replacement interval depends on your environment. For clean environments like data centres, we recommend every 2 years. In standard commercial buildings, every 12–18 months is typical. However, for industrial or high-dust sites, filters may need replacing every 3–6 months to prevent detector faults.

No. VESDA filters are dual-stage, high-efficiency cartridges designed to trap microscopic particles. Attempting to clean them with compressed air can damage the filter media and allow dust to enter the sensitive laser chamber, potentially causing permanent damage to the detector. Always use a genuine Xtralis replacement.

VESDA systems are designed with maintenance in mind. While they do require periodic filter changes and system checks, servicing is straightforward for trained engineers.

Once the new cartridge is installed, the filter counter must be manually reset to clear the "Filter Blocked" fault. This can be done using VESDA VSC software via a PC link, or directly through a handheld or remote VESDA Programmer.

Yes. It is vital to choose the correct model for your system. The VSP-005 is the standard cartridge for legacy models (VLP, VLC, VLF, VLS). The newer VESDA-E series (VEP, VEU, VES) requires the VSP-962 black filter. Check your detector's part number before ordering.

Typically, filters last 2–4 years, depending on the environment. In dustier conditions, they may need replacing sooner to keep the system working effectively.

VSP-005 is usually supplied as a single replacement filter cartridge, while VSP-025 is a pack quantity option. Always check the product listing before ordering.
