What are the solutions to eliminate dust and its toxic components?

04/21/2020


It is easy to implement simple actions to improve indoor air quality in your home or office.

To limit the accumulation of toxic dust, it is recommended to clean regularly with moistened cloths (washable microfibre or electrostatic cloth) and to de-clutter surfaces to make them easier to clean. Dust can also be removed with a vacuum cleaner equipped with a HEPA fine particle filter.

It is therefore advisable to ventilate during cleaning activities, as outdoor air is generally less polluted than indoor air.

The use of household products can emit a significant amount of pollutants from the indoor environment and ventilation helps to limit the accumulation of indoor air pollution generated during cleaning activities.


Which indoor air purifier should I choose to eliminate the pollution present in dust?

Pollution by pesticides (insecticides, herbicides and fungicides), plasticizers (phthalates), phenols (bisphenol-A), flame retardants (RdF) and perfluoroalkyls (PFAS) is present in the dust that accumulates in homes and offices.

The system used to purify indoor air must provide effective dust removal.

The indoor air purifier must be equipped with a HEPA filter.

Indeed, only a HEPA filter (high efficiency particulate air filter) can filter the air by retaining inhalable dust particles. Air treatment solutions are often presented as miraculous, but to be effective against dust particle pollution, the indoor air purifier must incorporate a HEPA filter of H13 quality or higher.

It is not possible to recommend brands and models of air purifiers because the information to evaluate performance in terms of pollution reduction is not publicly available.


How to reduce the intake of potentially dangerous compounds?

Phthalates are used to soften vinyl, but they are also present in some nail polish and personal care products. Prefer products where phthalates are absent.

Flame retardants are present in some foams and furniture. Look for natural materials or brands without flame retardants.

Phenols are present in some cosmetics and lotions and should be avoided.

PFAS include stain repellents, non-stick agents such as in non-stick pots, pans and kitchen utensils and should be avoided.

Ban PFC-treated packaging, which is unfortunately found in many mass-market food products and fast-food packaging. On some packaging there is a small "recycling" triangle. The inscription PC indicates the presence of polycarbonates. PFC is also found in Gore-tex clothing.

Do not wear shoes inside the house and use a natural fibre mat.
