Each purifier has different performance characteristics, so it all depends on the problem one has to solve. For example, if it is a persistent problem, we recommend a purifier with continuous operation (for example the CONFORT, SILENT or XTREME model): this is the typical situation of environments such as waiting rooms, bathrooms, changing rooms, kitchens, corridors or areas where there is little air exchange. In these cases, the purifier is installed, turned on and the problem resolved definitively. If, on the other hand, you are dealing with periodic and perhaps particularly intense problems, it may be better to choose a mobile purifier, to be turned on only when needed (or where needed, for example, by moving it from one room to another). These purifiers normally have a faster action (but which will also wear out over time). Typical situations include environments such as meeting rooms and offices, domestic environments (perhaps related to the presence of animals), home kitchens, etc. For these situations, depending on the size of the room, it is advisable to choose MINI, MIDI, MAXI or EXTRA models.

The differences are fundamental: perfumers cover odors; our products eliminate them, eliminating their cause (bacteria, molds, organic vapors of chemical origin, dust, allergens, viruses …), with a benefit for health.Finally our products require minimal maintenance (replacement of a lamp and / or filter, depending on the models and cleaning once a year), while perfumers require periodic replacement of cartridges and batteries that must be disposed of, with an important impact also in environmental terms.

There is no technology better than another, but there are different air quality problems and each problem has different solutions. For this reason, the best purifiers usually combine several technologies

If the problem is the dust to be eliminated (fine dust such as the famous PM10 or PM2.5 or mites or pollen), filter purifiers are particularly suitable (perhaps combined with an ionizer). But be careful that not all filters are the same and apparently similar filters have very different filtration capacities: always inquire about the characteristics of a filter because a ‘coarse’ filter will filter little or nothing. Also, each filter is effective until it becomes saturated, after which it will no longer work. Contact suppliers who are able to advise you based on your needs and remember that filters must be replaced periodically to remain effective. Finally, find out about the cost of filters. Several purifiers are ‘cheap’ but then force you to install very expensive captive filters.

Photocatalysis is a particularly effective natural process for solving problems related to the so-called VOCs or Volatile Organic Compounds. VOCs are chemicals often present in significant quantities in the environments in which we live. The origin of VOCs is different: they are generated by paints, coatings, packaging, furniture but also by the combustion process of hydrocarbons (for cars or for heating). Examples can be benzene, formaldehyde, acetone etc. In winter, when the windows are closed and there are few air changes, the concentrations can be particularly high and some of these substances at high concentrations are carcinogenic. Photocatalysis breaks down the molecules of these substances into simpler molecules that are not dangerous for humans. See the tests carried out by the University of Turin on VARYA CONFORT, VARYA SILENT and VARYA EXTREME purifiers that use photocatalysis (and other technologies), for more information on this and for the results.

It depends on what is the cause of the odors. If it is a matter of odors generated by materials (i.e. of chemical origin), the photocatalysis will surely have its effect (see the previous question). If, on the other hand, odors are caused by bacteria (such as in bathrooms), solutions such as radiation with UV light or ozone are particularly effective. In both cases, however, it is advisable to contact an expert to find the right product for your needs.

Yes and no … It is true that ultraviolet light at wavelengths included in the UV-C band (between 280 and 100 nanometers) modifies the DNA or RNA of microorganisms and prevents them from reproducing or being harmful. It is an established and effective technology that has been in use for decades in a wide variety of applications, such as the disinfection of food, water and air. However, a distinction must be made between the efficacy of UV-C light and the efficacy of the purifier as, for the bactericidal effect to occur, the air must be exposed to UV-C light for an adequate time. If, for example, the air flow is too high, the bactericidal action will be minimal. For this reason, we always recommend asking the supplier for data that certifies the performance of the purifier and not the generic performance of a lamp.

Unfortunately, the air flow is a parameter often used in a deceptive way by those who sell. In reality it is not so much the air flow that counts, but if the air is purified and by what. A good number of products on the market are little more than fans as they ‘move’ large quantities of air but their air handling capacity is very limited. For this reason, we always recommend asking the supplier for data certifying the performance of the purifier (and not just looking at the number of cubic meters / hour passing through the unit).

Our purifiers can be purchased or hired (with a formula where, for a monthly fee, we take care of the annual maintenance).

For VARYA CONFORT, SILENT and XTREME purifiers, installation is very simple: depending on the situations of use, the purifier can be placed on a surface or mounted on the wall. Each unit arrives complete with installation instructions and the necessary materials (plugs, feet, cable with socket and switch). The installation and maintenance manual can also be downloaded from this site. The other purifiers in the VARYA range do not require installation and can indeed be moved from one room to another as needed: all you need is a nearby power outlet

Yes, to remain efficient over time, all air purifiers need periodic maintenance. In general, this involves replacing the filters or the UV lamp and periodic cleaning of the device. The frequency of replacements depends on the model and the situation of use: in extreme situations of dusty or very polluted environments, it may be necessary to replace the filters after a few months. The UV lamp maintains its germicidal function for one year of uninterrupted operation. Photocatalysis and the ionizer do not require replacement of parts (but only periodic cleaning of the apparatus). We recommend that you always inquire well about the maintenance of a purifier before purchasing: particularly economical solutions can then lead to significant maintenance costs (or, reciprocally, to a product that no longer purifies after a short time)

For VARYA CONFORT, SILENT and XTREME products, maintenance is simple but we still recommend that it be carried out by an expert (installer or electrician), as the unit must be opened (in this case we will provide you with the UV lamp and filter). If of interest, we provide companies with the rental service for which we take care of providing the purifier and periodic maintenance, in exchange for the payment of a monthly fee. For the other products of the VARYA range, maintenance is very simple and can also be carried out by a non-expert user: just follow the instructions given in the operating manual or the illustrative videos on our website.
