In delicate environments such as museums and cultural institutions, preservation goes far beyond glass cases and security systems. The air itself — invisible, omnipresent, and often overlooked — is one of the greatest threats to the longevity of priceless artefacts. Our customers asked us to innovate to meet this challenge - and we delivered.
Whether it's a centuries-old painting, a rare textile or an ancient manuscript, materials deteriorate quickly in the presence of harmful airborne pollutants. That's where Brookaire's DeltaPleat™ GasGuard G8 filter enters the frame - a revolutionary solution designed specifically to address this unique challenge and elevate conservation standards across the board.
The Invisible Threat: VOCs in Museum Environments
Formaldehyde. Acetic acid. Sulfur dioxide (SO₂). Nitrogen dioxide (NO₂). Ozone (O₃).These gases - known as volatile organic compounds (VOCs) and atmospheric pollutants - are scientifically proven to corrode, discolor, and weaken the fibres and surfaces of historical artefacts.
They can be introduced through everything from building materials and cleaning supplies to outside air, and they don't discriminate. Wood, fabric, paint, leather - all are vulnerable.
The risk isn't just theoretical. Many institutions are already reporting significant damage to collections due to insufficient environmental control. Unfortunately, traditional filtration methods often fall short, especially when it comes to capturing gases at the molecular level.
Enter DeltaPleat™ GasGuard G8: A New Era in Museum Filtration
Brookaire's DeltaPleat™ GasGuard G8 is a V-bank gas phase air filter developed specifically for the preservation needs of museums, galleries, libraries, and archives. Independently tested by Fiatec, the G8 delivers unmatched gas-phase filtration across five of the most dangerous airborne threats to museum environments:
- Formaldehyde
- Acetic Acid
- Sulfur Dioxide (SO₂)
- Nitrogen Dioxide (NO₂)
- Ozone (O₃)
Backed by industry-grade performance, the DeltaPleat™ GasGuard G8 offers:
- 60% better gas capture than traditional carbon filters
- 50% improved SO₂ adsorption (with 107% greater capacity)
- 40% better acetic acid capture
- 60% higher NO₂ adsorption efficiency
- 50–70% better ozone adsorption performance
These gains are more than technical stats - they represent fewer conservator interventions, longer lifespans for artwork, and greater peace of mind for facility managers.
Plug-and-Play Protection with Serious Results
The DeltaPleat™ GasGuard G8 isn't just powerful - it's practical. Designed as a plug-and-play solution, this 24x24x12-inch V-bank filter fits directly into most commercial HVAC systems. That means no expensive retrofitting, and immediate, measurable protection.
With a media velocity of 10 cm/s, tested under ISO 10121-1 standards, and engineered for temperature and humidity stability, GasGuard G8 maintains reliable performance even under fluctuating environmental conditions. For museum operators, it also delivers operational advantages:
- 29% reduction in labor and waste due to less frequent change-outs
- Lower energy costs thanks to a minimized pressure drop
- Reduced carbon footprint, aligning with green building goals and sustainability initiatives
And yes - like all Brookaire filters - the G8 is made in the USA to the highest quality standards.
Why This Matters
Environmental conditions are at the heart of conservation. For every UV-blocking film applied to a gallery window, there needs to be a matching level of care for the air inside the room. With formaldehyde capable of weakening textiles and acetic acid known for causing structural damage to wooden objects and photographs, there's no question that air filtration is no longer a back-of-house concern - it's a front-line conservation strategy.
With DeltaPleat™ GasGuard G8, museums are now equipped with a scientifically validated, performance-driven filter designed with the very specific needs of artefact preservation in mind.
Future-Proofing the Past
The collections in our museums represent centuries of human creativity, history, and knowledge. Protecting them requires more than temperature control and humidity readings - it demands proactive defense against the microscopic enemies that surround us.
The Brookaire DeltaPleat™ GasGuard G8 filter is a powerful ally in this mission. For facility managers, HVAC professionals, and conservators alike, this filter marks a major advancement in environmental control - providing the confidence needed to protect treasures for generations to come.
