HEPA Filters

More About HEPA Filters

High Efficiency Particulate Air (HEPA) filters are designed for use when the highest degree of air quality is required, used in industrial, pharmaceutical, food production and healthcare applications. Constructed with pleated paper, composed of a mat of randomly arranged fibres, HEPA filters trap particles through interceptions (particles adhering to the fibres), impactions (particles colliding with a fibre and embedding into it) and diffusion (small particles being blown or bounced and captured via the other two methods).

HEPA filters will remove a minimum of 99.97% of particles at a size of 0.3 microns, with the highest grade HEPAs removing 99.995% of particles at this size. The HEPA paper is pleated to increase surface area, this reduces the initial pressure drop/air resistance, and increases the dust holding capacity. HEPA filters should be used in conjunction with pre-filters, such as panel and bag filters.

We construct all of our deep pleat HEPA filters in our Dorset factory to the BS EN 1822:1999 standard. Our H13 and H14 HEPAs are individually smoke leak tested and come with a test certificate. We manufacture with either wood or galvanised steel case, with our wooden HEPA filters being fully incinerable.

HEPA stands for High-Efficiency Particulate Air, and a HEPA filter is a type of air filter that can capture 99.97% of particles as small as 0.3 microns in size. This makes them highly effective at removing airborne contaminants such as dust, pollen, mold, and bacteria.

HEPA filters are highly effective at improving indoor air quality by removing a wide range of airborne contaminants. They can help reduce allergies, asthma symptoms, and other respiratory problems by capturing dust, pollen, pet dander, and other allergens. HEPA filters can also help prevent the spread of airborne diseases by capturing and trapping bacteria and viruses.

HEPA filters are commonly used in air purifiers, HVAC systems, vacuum cleaners, and other air filtration systems. They are also used in hospitals, clean rooms, and other settings where air quality is critical.

The frequency of HEPA filter replacement varies depending on the usage and the environment they are used in. Generally, it is recommended to replace HEPA filters every 6 to 12 months. However, this may vary depending on the manufacturer's instructions and the level of pollution in the environment.

HEPA filters are highly effective at capturing and filtering out airborne particles, including viruses such as COVID-19. However, it's important to note that HEPA filters alone are not a substitute for other preventative measures such as social distancing, mask-wearing, and hand hygiene.
