The P341 filter is a combination of a HEPA (fine particle filter) with a Granulated Activated Carbon Filter.
The HEPA filter to remove dust particle down to 0.3 of a micron
The Granulated Activated Carbon Filter adsorbs odours, tobaccco smoke as well as harmful chemicals like formaldehyde and VOCs (volitile organic compounds).

Activated carbon, also called activated charcoal, carbo activatus or an "AC filter", is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Due to its high degree of microporosity, just one gram of activated carbon has a surface area in excess of 500 m2.
Because of its super porous texture active carbon is able to attract, adsorb and neutralise smaller particles like organic gases, odours and some chemical compounds. These particles are too small to be trapped by other types of air purifier filters.
Activated carbon is a form of carbon that has been treated to make it extremely porous giving it a very large surface area available for the adsorption of chemical compounds. Activated carbon primarily adsorbs organic chemicals along with some larger molecular weight inorganic compounds. One gram of activated carbon has a surface area about one tenth the size of a football field.
If you would like to remove smells, gases or some chemicals from the air in your home an activated carbon filter is a very effective part of an efficient air purifier.
HEPA is short for for "High Efficiency Particulate Air" or "High Efficiency Particulate Arrestance." True HEPA refers to a filter that is manufactured, tested, certified, and labeled in accordance with current True HEPA filter standards. The True HEPA filter must capture 99.97% of the particles down to 0.3-micron particles in the air passing through it.
Efficiency is typically greater than 99.97% against larger or smaller particle sizes. Particles larger than 0.3 microns are more easily trapped, or intercepted, by the media. Smaller particles often lack sufficient mass to penetrate the media.
To meet the minimum requirements of a True HEPA filter, the filter must be tested and certified to prove that it will remove at least 99.97% (9,997 out of 10,000) of particles 0.3-micron in diameter from the air passing through the filter. Particles of that size are about 300 times smaller than the diameter of a human hair, and 25 to 50 times smaller than we can see. Manufacturing a filter with HEPA filter media does not mean that the filter itself meets True HEPA efficiency requirements.
With filtration down to 0.3 microns and 99.97% efficiency the True HEPA filter will remove most dust, pollen, pet dander, mould spores, mites, cigarette smoke and even particles as small as bacteria and some viruses.
Whether you purchase air purifiers, dehumidifiers or water filters, or any of their replacement parts we offer you peace of mind. We will add your name to our reminder service. In accordance with the manufacturers' guidelines we will send you a gentle reminder that your unit may need replacement parts. Maintaining its efficiency will continue providing you a healthier environment.
We will be able to supply you with your required replacements. We maintain stock levels of filters and cartridges even after a manufacturer may bring the original unit to an end. This means our customers can rest assured of our commitment to servicing their requirements long into the future.
If you do not wish to be included in our service then we can simply unsubscribe you. Similarly, if you have not purchased the units or replacements from us before you may ask to be included in our service for future use.
With best wishes
