How to Choose Best Air Purifiers?

We all want to breathe pure, contaminant-free air in our homes, especially people with asthma and allergies. A proper purifier can bring benefits in this sense, but it is good to inquire adequately before purchasing. Some operate on ozone and may even be harmful because they irritate the lungs.

Read the guide to find out what the best air purifier on the market can be for you.

Effectiveness of The Filtration System

The first aspect that the user will evaluate to determine which air purifier to choose will be its sufficient filtration capacity.

The systems that produce ozone (also called activated oxygen or trivalent oxygen) would be able to break down microorganisms and particular odors.

Still, great care must be taken because ozone is harmful to the body. Ozonizers, such as infrared thermometers, were among the most used devices as a consequence of the known facts that hit Italy.

Some models use an ionizer (which can also produce ozone), which positively or negatively charges the substances suspended in the air, forcing them to attach themselves to the nearest surface. In this way, however, neither gas nor odors are eliminated, and the walls can get dirty.

Electrostatic systems reach a maximum efficiency of 95%, which can be drastically reduced. Here too, gas and odors are not eliminated just as it is not able to delete them the presence of a UV light that is claimed to kill pathogens.

The user will then carefully evaluate those HEPA (High-Efficiency Particulate Air) systems developed during the Second World War even to prevent the emission of radioactive particles from nuclear reactors.

They have a minimum effectiveness of 99.97% and can block particles down to 0.3 microns. Filters (which generally have a significant price) must be changed regularly. Otherwise, they are useless.

The attentive consumer will notice that some models present multiple filtration systems simultaneously for greater efficiency and will seek the Clean Air Delivery Rate (CADR).

The measure of the rate of release of air free from aero-allergenic particles by a purifier, measure objective and reliable comparison between purifiers: a value above 350 is considered excellent, below 100 poor.

Covered Area

There are unique air purifiers for the whole house for which installation by a specialized technician is recommended. Still, those who read a guide to choosing the best economical air purifier will see that the most popular models are portable ones with a handle. Or wheels.

The various purifiers’ dimensions are not significantly different from each other, but an important aspect to which the user will have to refer is the more or less large area that the purifier can cover.

If the environment to be purified is unique and is small (for example, 10 square meters), only the models capable of managing this space will be taken into consideration, not the higher ones.

Some models cover areas of 20 square meters as can be a large room or even 30 square meters, as in the case of a small office.

The user will evaluate whether the purifier should be moved from one environment to another or if it must always remain in the same situation.


The user who compares prices, performance, and technical characteristics can also insert the purifier’s silence among the parameters of his ranking, knowing that the purifier must always be kept on; otherwise, he cannot make improvements to the air you breathe.

From this point of view, it will evaluate the best models that are clean and highly efficient, even in a low setting. The high (and noisy) adjustment of the fan can be set when you are not at home.

The consumer who is attentive to noise, therefore, will evaluate whether or not the purifier has the possibility of making these adjustments and how many decibels are emitted for each level.

Room Size

As we have seen above, the action of air purifiers covers a certain number of square meters. In this way, they can adapt to the needs of various types of houses. You will need to keep this in mind, as too weak, a purifier will not be able to meet your needs adequately. While a too powerful one will waste your energy, and therefore money.


When buying any appliance, it is essential to know what kind of maintenance it needs. You will need to check what the filter cleaning intervals are. As well as replacement intervals. In this sense, also remember to evaluate the price of the filters.


You usually buy a single air purifier for the whole house. Therefore, you will need to move it from one room to another to use it.

Consequently, it is necessary to take into account the ease with which the device can be moved from one side to another. Otherwise, when running it you may find it too bulky or uncomfortable.


Therefore, the purchase guide serves to collect useful information to determine which can be the best brand of air purifiers and not to make a mistake because it invites you to carefully evaluate essential aspects such as the efficiency of filtration and indoor air.
