P3 replacement filters promise high-efficiency particle removal for respirator users, suitable for dusty workshops and building sites. Lower breathing resistance helps wearers stay comfortable during long shifts. Are STANLEY P3 Replacement Filters a reliable, easy-to-fit choice for tradespeople and keen DIYers?

⚡ At a Glance
  • Filtration Efficiency: Hepac advanced filter technology removes up to 99.99% of airborne particles
  • Best for: Users of Stanley Half Mask and visor needing high-efficiency particulate protection
  • Not ideal for: Tasks requiring gas or vapour filtration rather than particulate protection

Designed for use with Stanley Half Mask and Visor, the filters use Hepac technology to capture fine particulates. A low-resistance construction and pre-filter reduce breathing effort and help prevent clogging.


Easier breathing during extended wear – with Hepac advanced filter technology

Hepac advanced filter technology is specified to remove up to 99.99% of airborne particles while being engineered to keep breathing resistance very low. The media balances fine-particle capture with airflow to reduce inhalation effort.

Lower breathing resistance cuts user fatigue on long shifts, making respirator use more comfortable and sustainable across a working day.

Longer service life – with integrated pre-filter protection

A built-in pre-filter captures larger dust and debris before they reach the Hepac media, helping to prevent rapid clogging of the main filter. That staged approach maintains filtration performance for longer periods.

Fewer replacements are needed in dusty environments, so filters stay effective for longer and require less frequent changes.

Simple, secure fit – with compatibility for Stanley half masks and visors

Designed specifically for use with Stanley Half Mask and Visor and Half Mask, the filters match the connection points for straightforward installation. Replacement is intended to be quick and repeatable.

Fast swaps keep downtime to a minimum on site, and a reliable fit helps maintain a consistent seal during routine tasks.
