How It Works

About Filter Replacement

Regular filter replacement is essential to maintain healthy indoor air and reduce strain on your HVAC system.

At ARM Environments, we specialise in intelligent, data-led filter replacement services for non-residential buildings. Our process begins with an initial assessment of your ventilation system, filter types, and building use — allowing us to recommend the right replacement strategy.

Where most contractors replace filters on a fixed schedule, we offer a smarter approach. Using pressure drop monitoring, air quality data, and usage patterns, we determine the optimal replacement interval to balance air quality, energy efficiency, and cost.

We supply and install high-performance filters – including ePM1 and ePM10 models – selected for your system’s design and filtration goals. Our engineers ensure every filter is installed to standard, sealed properly, and documented for compliance.

Service Benefits

  • Improve indoor air quality
  • Lower HVAC energy costs
  • Extend system lifespan
  • Comply with regulations

Aston Martin Racing Team takes IAQ pole position with ARM Environments

Objectives

We were contacted in 2022 to support the development of a new state-of-the-art 15,000m² HQ for Aston Martin's racing team. This space would occupy two floors and encompass varied spaces enabling all aspects of Formula 1's elite car design, cutting-edge R&D, top-of-the-line manufacturing equipment, efficient assembly, and high-tech testing. The team specified that low levels of particulate matter (PM), volatile organic compounds (VOCs), and odours would be required to maintain a safe, healthy, and productive workspace.

Solutions

To meet these specifications, we used some of the latest and greatest electronic air cleaning solutions. We utilised fan coil bipolar ionisers unique to ARM to effectively reduce the levels of total volatile organic compounds (TVOCs) and PMs. We also installed UVC filters into the air handling units (AHUs) which keep the heating and cooling coils clean and eliminate organic matter like bacteria which are caught in the filter. This UVGI air purifier technology keeps the internal components clean, resulting in lowered maintenance costs in the long-term.

Results

ARM were effective in collaborating with the client to deliver outstanding air quality in their new HQ. We successfully met their key design specification criteria with our industry-leading, future-proofed air purification methods. Furthermore, by installing UVGI systems, the company will be saving money in the long term, due to less frequent maintenance visits, whilst also enjoying fresh, sterile air.

Challenges

  • Specific design specifications
  • High profile project
  • Industry focus on sustainability & wellbeing

"In-person collaboration is often an essential requirement for high-performing teams. It was critical that worries about IAQ did not distract the Aston Martin Formula 1 team from their jobs. Their building has been fitted with the latest clean air systems, so they can concentrate on building a championship winning car".

Filter Replacement FAQs

How often should HVAC filters be replaced?

It depends on usage and air quality, but many systems require replacement every 3–6 months. We use data to determine the most efficient schedule for your building.

What types of filters do you supply?

We provide a full range of filters, including G4, F7, ePM1, and ePM10 – selected based on your system design, air quality goals, and environmental conditions.

Can you replace filters in older HVAC systems?

Yes. We assess your system and can retrofit suitable filters, helping you meet modern air quality standards even with legacy equipment.

Is filter replacement part of planned maintenance?

It can be. We offer one-off replacements or scheduled programmes tailored to your maintenance plan, compliance requirements, and operational needs.
