You have probably already heard of air purifier, perhaps without knowing what it really was. To help you understand these somewhat complex products, here is an overview of what you need to know about them first and especially how to choose the one that suits you best.
What is an air purifier?
Air pollution is no longer a mystery for all of us, as its consequences are numerous and its effects on our health dangerous. Although we can not act easily on a large scale to totally eradicate it, we can already start at home thanks to an air purifier.
An air purifier is a device capable of purifying the ambient air of your home to improve its quality.
An indoor air purifier is therefore an effective solution against mites, tobacco smoke, pollen, toxic emissions, fine particles, or any toxic substance found in our air.
With these technologies, the air purifier will be able to neutralize pollutants toxic and invisible to the human eye, thus reducing the risk of disease.
How to choose an air purifier?
To be sure to acquire the best air purifier that really meets your needs, you will need to learn about several criteria. In particular, start by checking the various technologies that it integrates to get an idea of its real effectiveness in the field. Here, you will have to choose between the most effective purification methods, including HEPA filtration, activated carbon filtration, but also ionization or photocatalysis.
This done, do not forget to take a look at its capacity so that the air purifier is perfectly adapted to the dimensions of the room in which you want to install it. Also find out about ease of maintenance, noise level, power consumption and the cost of replacement filters.
In order for you to find the rare pearl adapted to your specific budget and needs, you will first need to review some models.
How do we choose air purifier?
Useful for controlling indoor air quality (which according to Air & me, is eight times more polluted than outside air) and necessary if you suffer from allergies, asthma or other respiratory problems, air purifiers are difficult to choose, if only because of the many models on the market and the use that we want to make.
Note that an air purifier does not have the same role as a fan (which ventilates the air) or an air conditioner (which cools the air).
To establish this selection, we first looked at the different types of existing filters:
The HEPA filter is the best known and most effective of all. It consists of a very dense paper that filters most airborne pollutants, including the most harmful ones. True HEPA certified products are the most reliable because they will eliminate up to 99.97% of microscopic particles! However, this type of filter has no action against odors and chemical fumes.
Ionic filtering: it is a filtering technology by the emission of a cloud of ions charged in the air. The ionic filter removes dust, spores and fungi, VOCs, and even some bacteria and viruses. However, this filtering system is not recommended for people with asthma because the ion generator releases ozone residues into the air, which are considered to be irritating to the lungs.
Carbon filtration or activated carbon: with this system, several million absorbent pores suck fumes, gases and odors. This filter is never used alone, because its primary function is not to eliminate particles harmful to health but rather to rid the air of those that emit bad odors.
Ultra violet (UV) light filtering: it is a technology that emits an invisible light that attacks the pollutants by using the ultra-violet ray UV-C band. Its main goal is to kill bacteria and viruses to leave the environment clean and sterile.
The pre-filtering of the air: it makes it possible to clear the large particles in the air before passing it through the filter (HEPA or other) proper. Indeed, if the latter was in permanent contact with these large particles, the purifier would be less effective and less durable. The pre-filter, usually washable, is often made of woven nylon or foam.
