Functions of air purifiers

A noteworthy characteristic of contemporary air purifiers is the inclusion of air humidification capabilities. The task of “cold self-regulating evaporation” is adeptly fulfilled by the integrated plastic discs, obviating the need for replacement filters in this humidification process.

The latest iterations of air purifiers truly merit the title of supreme air purifiers, representing comprehensive climatic ensembles that embody a threefold system of air purification, humidification, and aromatic infusion.

The air preparation procedure within these climate systems commences with the air traversing an anti-allergenic filter, followed by the passage through an evaporator imbued with antibacterial properties. Subsequently, the air stream proceeds through a charcoal filter and an aromatic diffusion mechanism employing essential oils. Once the air attains the pinnacle of readiness, having undergone a purification level of 99.9%, it further undergoes ionization to confer prophylactic and invigorating benefits.

Criteria for choosing a purifier

In the domestic market, an abundance of climatic equipment renders the selection of an appropriate air purifier for one’s home a daunting task. To ensure that one does not grapple with this decision alone, it is essential to acquaint oneself with the merits and demerits of different devices.

Room size

Every air purifier is tailored to accommodate a specific room dimension, necessitating an initial assessment of the room’s size. Pose a simple query to yourself: “Do you intend to acquire an air purifier for each individual room, or can it be conveniently transported?”

Should the intention be to procure a separate air purifier for each room, then the selection criteria should be contingent upon the room’s area, constituting the operational territory for the air purifier.

In the event that the device is envisaged to be moved from one room to another, one ought to prioritize the area of the largest room within the abode or office. In such cases, the optimal air purifier should be designed to cater to a substantial expanse, for insufficient power would undermine the quality of air purification.

For relatively compact spaces, a car air purifier may be a viable option, enabling the cleansing of air in both the vehicle and the home with a single device.

Dust levels in the room

Preliminary determination of the specific issues to be addressed with the aid of an air purifier is prudent, as it has a bearing on the device’s price. In instances where a considerable amount of dust is prevalent in the room, the following preferences are advisable:

Opt for a purifier equipped with plasma filters. Such filters possess an electrostatic charge that attracts dust, and they are also easily washable, negating the need for frequent replacement filters. However, if the dust accumulation is excessive, electrostatic cleaners may prove insufficient, as they solely eliminate 90% of dust particles.

Select a cleaner outfitted with a HEPA filter. This type of filter is low-maintenance, necessitating monthly vacuuming and replacement at least once a year, contingent upon the level of air pollution. The unit represents the most efficacious defense against dust, as it creates an impenetrable barrier to the passage of air, ensnaring even microscopic bacteria and minuscule specks of dust within the filter’s pores. When seeking an elevated degree of dust purification, a unit equipped with a HEPA filter is regarded as the epitome of excellence in home air purification.

Consider an ionizer purifier. This apparatus precipitates airborne dust onto horizontal surfaces, effecting air purification. Such devices do not accumulate dust within their interiors, thereby obviating the need for filter replacement or washing. Ionizers prove suitable for those desiring to evade the additional expenses associated with maintaining a cleaner, provided they are willing to regularly remove dust from surfaces using a cloth or vacuum cleaner.

Allergic reactions

The primary concern lies in the fact that minuscule imperceptible dust particles can trigger bouts of sneezing, allergic rhinitis, and inflamed eyes in individuals prone to allergies. The preferable choice should be:

An air purifier equipped with HEPA filters. This ingenious device effectively eliminates the tiniest dust particles suspended in the air, boasting an impressive cleaning efficiency of approximately 99.9%. It stands unrivaled as the epitome of allergy prevention.

Air purifiers with electrostatic filters. Although these devices are less potent, as dust particles are solely drawn to the plates through electric charges, and with the plates spaced apart, some particles manage to evade capture. The cleaning efficiency ranges from 81% to 90%.

Air washers. These remarkable devices pass the air through a fine mist of water, effectively cleansing it. The water effortlessly washes away the smallest pollutants. The most efficient air washers incorporate an ionization process beforehand, enhancing the attraction of charged dust particles to the drum plates. In such cases, the cleaning efficiency can reach up to 95%.

Humidifier cleaners. These devices humidify the air by utilizing an evaporative filter soaked in water or water sprayed within the device itself. However, their efficacy falls short of 90%.

Dust mites and smoke

Prior to selecting an air purifier, it is crucial to acknowledge that allergies can be triggered not only by dust but also by fungi, mold, dust mites present within it, as well as tobacco smoke. By eliminating these microscopic inhabitants, the underlying cause of your allergies can be eradicated. Ozonators and photocatalytic air purifiers, fortified with filters designed to extract dust particles, can aid in combating mold and dust mites.

Air purifiers ozonators. Ozone possesses the remarkable ability to decompose toxic substances and smoke into the water and harmless carbon dioxide, effectively eliminating germs and microorganisms due to its potent oxidizing properties. It is important to note that such devices should only be used when the room is unoccupied.

Photocatalytic air purifiers. By leveraging the interaction between the catalyst and UV light, ionizers efficiently purify and disinfect the air, annihilating microbes and breaking down chemical compounds and toxic constituents present in smoke. It is advisable to acquire an ionizer equipped with an electrostatic filter, as it can be more easily cleansed of accumulated nicotine residues.

Odors and Decontamination

Air purifiers possess the remarkable capability to cleanse the air within a room, ridding it of automobile and industrial emissions seeping through windows, diverse kitchen odors, putrid aromas, ashes, office equipment emissions, construction materials’ scents, and pet-related fragrances. Additionally, they serve as invaluable tools for air disinfection, especially during viral disease outbreaks.

Photocatalytic air purifiers. These exceptional devices are capable of decomposing any odors even in the presence of individuals, efficiently disinfecting and purifying the air through the utilization of ultraviolet light and photocatalysis. This process effectively neutralizes the majority of viruses, germs, and bacteria.

Air purifiers-ozonators. These devices assume responsibility for oxidizing and decomposing any chemical and organic constituents present in the air, including odors. In standard operation mode, these devices employ ionization to disinfect the air. Moreover, ozone, when used in moderate amounts, holds significant health benefits and acts as a natural immune booster.

Air purifiers with carbon filters. Odor molecules adhere to the surface of charcoal granules within these devices, where they are effectively adsorbed into microscopic pores. However, the efficacy of carbon filters falls several times short when compared to their photocatalytic counterparts.

Frequency of usage

Optimal operation of the air purifier and continuous maintenance of clean, high-quality air in the room is vital for the well-being of its occupants. If you intend to purify the air constantly and economical operation is a priority, it is advisable to select an air purifier with low energy consumption.

If occasional use of an air purifier aligns with your preferences, then purifiers-humidifiers and air washers may not be suitable, as they cannot be left idle with water for extended periods, as they may turn stagnant. However, if you are determined and willing to drain the water, disassemble the device, and dry its components every time, the purchase of such devices should not deter you.

Care for the apparatus

Sincerely assess the amount of time you are willing to dedicate to your faithful aide to determine the ideal air purifier for your needs. While the appliance diligently purifies the air for you, it also requires regular cleaning; otherwise, it will cease to function and eventually deteriorate.

If you are inclined to attend to your air purifier frequently, opting for a humidifier or air washer is recommended, as they require replenishment and changing every three days as needed.

If devoting attention to your air purifier once a week is convenient for you, an electrostatic air purifier is a perfect choice. It necessitates cleaning the electrostatic plates once a week.

If minimal effort in cleaning is desirable, and remembering to clean the device once a month suffices, we recommend considering an ionizer cleaner, an ozonator cleaner, a photocatalytic cleaner, or a cleaner equipped with replaceable HEPA filters. These devices only require vacuuming once a month.

Filters for your air purifier

Determine whether you are willing to invest in maintaining the chosen air purifier model or if you prefer to minimize expenses while ensuring clean air in your room for the foreseeable future.

If additional costs do not deter you, feel free to purchase air purifiers with filters, as they guarantee the highest level of air purification due to multiple stages of filtration. If added expenses are burdensome, consider filterless air purifiers such as ionizer purifiers, ozonator purifiers, plasma and photocatalytic models, as well as air washers.

If you opt for a purifier with replaceable filters, ensure that it supports the ionization function. When air passes through any filter, it loses its natural charge, rendering it unsafe for inhalation, potentially leading to various illnesses.


To determine the most suitable air purifier for your needs, consider the placement within your house to seamlessly integrate it into the interior. Various models are available, including those designed to be positioned 1.8 meters above the floor, floor-standing versions, wall-mounted units, or plug-in purifiers that directly connect to an outlet. Many devices effectively cleanse the air when installed at a specific distance from the walls, typically requiring a separation of 10-50 centimeters.

Consider the number of fan speeds you require. Is it essential to have intensive or background air purification and reduced noise levels during nighttime? Perhaps you desire an assistant with an abundance of features, such as air pollution sensors, a timer for measuring humidity levels and enabling automatic cleaning in specific modes, a hygrometer, night lighting, and the option to disinfect the air in unoccupied spaces.

Bear in mind that additional features come at an extra cost, so it is advisable to determine in advance whether you genuinely require them or if they will only be utilized initially or cause confusion with an excessive number of modes and buttons. Make a decisive choice to avoid regretting an impulsive decision later.

Consider whether you sleep soundly at night or are frequently disturbed by extraneous noises. If this factor holds significance, select an air purifier that operates with reduced noise levels during the night or prioritize silent air purifiers such as ionizers or photocatalytic models, fanless units, or models with the option to deactivate the fan.
