SWKI VA101-01:2025 is a technical standard that outlines compliance requirements for air filter systems in air handling technology, published by the Swiss Association of Engineers and Architects (SWKI).

Purpose and objectives

The primary aim of the SWKI VA101-01:2025 is to provide a comprehensive framework for the classification, testing, and application of air filter systems used in air handling technology. This standard seeks to enhance air quality in built environments by establishing robust criteria for air filters, ensuring they effectively capture air contaminants. By doing so, it supports regulatory compliance and promotes technological advancements in air filtration systems, ultimately contributing to healthier indoor air quality and better building performance.

Scope: who must comply

The SWKI VA101-01:2025 standard applies to a wide range of stakeholders involved in air handling technology, including:

• Manufacturers of air filter systems
• Engineers and architects specializing in building technology
• Facility managers overseeing air quality in commercial and industrial settings
• Regulatory bodies involved in air quality standards

Typical industries include healthcare, commercial real estate, manufacturing, and any sector where air quality is critical. Organizations that aim to implement or upgrade air handling units to meet modern air quality standards must ensure compliance with SWKI VA101-01:2025.

How SWKI VA101-01:2025 relates to other standards

SWKI VA101-01:2025 is closely related to several key standards that guide air filtration technology:

• EN ISO 16890: This standard outlines the testing and classification of air filters, focusing on their efficiency against particulate matter.
• EN 1822-1: This standard specifies the testing methods for high-efficiency particulate air (HEPA) and ultra-low penetration air (ULPA) filters, which are crucial in critical environments.
• VDI 3803 Blatt 4: This guideline complements SWKI VA101-01:2025 by addressing the methodology for assessing indoor air quality in various settings.

Revision history and current status

The SWKI VA101-01 standard was first published in 2025 and has undergone revisions to incorporate feedback from industry stakeholders and advancements in technology. The most recent revision focuses on improving testing methods and aligning with international standards like EN ISO 16890. This ensures that the compliance requirements remain relevant and effective in enhancing air quality and filter performance across various applications.
