The presence of unpleasant odors at home is widespread. These bad smells usually come from the kitchen, new or old furniture, faux leather, electronic or household accessories, cleaning products, paint or tobacco smoke, for example. Bad odors are related to organic compounds released into the air. As long as these organic compounds are present in the air, the bad smell in the rooms will persist.
These compounds are tiny (several microns at most), so a high-performance device and filtration of excellent quality are required to remove these pollutants effectively. The presence of these pollutants in the air sometimes comes from uncomfortable substances such as cooking odors but can also be harmful by triggering severe diseases with materials such as tobacco smoke, VOCs from furniture and paints, etc. Against these substances, it is highly recommended to use air purifiers with activated charcoal filters to treat air and odors as efficiently as possible, which will allow you to breathe healthy air.

The frequency of allergic and respiratory problems is high in the population. The prevalence of allergy is about 17%, and that of asthma is about 7%. In children, the influence of environmental factors, including indoor air quality, is well known regarding the origin of these problems. Not surprisingly, there is now a public trend to purchase home air purifiers, whether they are centrally heated appliances or portable appliances. Health professionals, especially doctors, are often questioned about the usefulness of these devices to prevent health problems.
How purifiers work
The general principle of operation of domestic air purifiers is relatively simple. These are portable or stationary devices equipped with an air suction system and filters to capture contaminants, mainly particles, during the passage of air in the device. Filters can be installed alone or in sequence. Portable appliances may be on the table or floor while stationary machines are mounted on the central heating ventilation system. You can read review of the best purifiers here.
There are three types of air purifiers: mechanical, electronic and ionization. The operation of mechanical purifiers is based on the impaction of the particles on the many fibers of which the filters are made, and the filters also retain some substances. The HEPA (High-Efficiency Particulate Air Filter) purifier is an example of a mechanical type apparatus comprising a high-density filter. This type of filter, built into a portable device, was developed for military purposes during the Second World War by the United States Atomic Energy Commission to retain radioactive dust.
Efficiency of devices
Particles, gases or vapors may contaminate indoor air. From a health point of view, it is essential for the purifier to reduce the concentrations of respirable and non-respirable particles. Breathable particles have a diameter of fewer than 10 microns (or thousandths of a millimeter).
