How It Works

About Epm10 & Molecular Filters

ARM Environments supplies and installs high-efficiency ePM10 and molecular filters for non-residential buildings across the UK. These filters are essential for protecting both occupants and ventilation systems from airborne contaminants that standard filters can't remove.

We begin by assessing your current HVAC setup, air quality requirements, and any known pollution risks — such as roadside location, industrial emissions, or indoor sources of VOCs. Based on this, we recommend the right filtration combination.

ePM10 filters are designed to capture larger particles such as dust, pollen, and fibres, helping protect against respiratory irritation and maintain system hygiene. Molecular filters go a step further, removing gases, odours, and volatile organic compounds (VOCs) using activated carbon or chemically treated media.

We install all filters to manufacturer specifications, ensuring correct sealing to prevent bypass. We also provide lifecycle advice and replacement schedules to maintain consistent performance and compliance with indoor air quality standards.

Epm10 & Molecular Filters FAQs

What does ePM10 mean?

ePM10 is a filter classification under ISO 16890. It refers to filters that capture particles with diameters of 10 microns or smaller, such as dust, pollen, and fibres.

What do molecular filters remove?

Molecular filters remove gas-phase pollutants like VOCs, odours, and chemical fumes – contaminants that standard particle filters can't capture.

Do I need both filter types?

It depends on your building and air quality goals. We’ll assess your needs and recommend either particle-only, molecular-only, or combined filter systems.

How often do these filters need changing?

Filter lifespan varies based on air quality and usage. We provide tailored replacement schedules based on monitoring data and manufacturer guidance.
