Frequently asked questions

INT4SAN is a professional Italian air purification system, also available with dehumidification. It was designed for the specific needs of spaces where cultural heritage is stored and displayed. According to the manufacturer, it was developed with specialists in conservation, restoration and biological protection of heritage — it is not an ordinary household purifier.

No. INT4SAN purifies the air, and the DRY version also dehumidifies it. It acts on the storage environment, not directly on objects — collections are never treated inside the device. It does not replace specialist disinfection or pest treatment when needed, but helps keep conditions in which biological threats are less likely to return.

Paper, parchment, wood, leather and textiles constantly interact with their surroundings. Excess humidity encourages microbes and deforms hygroscopic materials, fungal spores can become a threat under favourable conditions, dust soils surfaces, and swings in temperature and humidity stress objects. Repairing the damage is costly, slow and sometimes impossible without altering original material — so prevention is cheaper and safer than later intervention.

Preventive conservation means reducing risk factors before they damage objects. INT4SAN can be one element of it — alongside temperature and humidity monitoring, proper ventilation, housekeeping procedures and regular condition checks. The most effective protection is often the one that avoids later intervention.

Air passes through five stages: (1) an F7 pre-filter captures dust and suspended particles, (2) fans force the flow through each element, (3) a UV-C module limits microbial activity, (4) a high-efficiency HEPA H14 filter retains very fine particles, including those carrying biological contaminants, (5) an activated carbon filter reduces selected gases and odours.

No. It works through filtration and built-in technology (F7, HEPA H14, activated carbon, UV-C), not by spraying biocides. This matters for the safety of both collections and the people working around them.

UV-C can limit microbial activity, but real effectiveness depends on exposure parameters and system design. Likewise, the carbon filter's effect on specific substances depends on filter type and operating conditions. That is why we say the system supports, rather than guarantees, specific outcomes.

Air flow 350–1400 m³/h, power 100–400 W (max), weight 100–170 kg, body 800 × 500 × 1800 mm (1950 mm with wheels), sound level 40–59 dB, 230 V AC. The unit is mobile on wheels and needs no ducts that would require periodic cleaning.

According to the manufacturer's brochure, sound power is 40–59 dB depending on fan speed. Operation can be tailored to the room, and the control panel supports day and week programmes.

INT4SAN AIR purifies the air — reducing dust, suspended particles and selected biological and gaseous pollutants. INT4SAN DRY combines the same multi-stage purification with dehumidification. Both have F7 and HEPA H14 filtration, UV-C, activated carbon and a mobile body.

When air quality is the main challenge: collection stores, exhibition halls, reading rooms, galleries and spaces where heritage objects are handled. AIR also helps prepare rooms for collections returning after conservation treatment.

When air quality and excess humidity are a joint problem — archive and museum stores, basements, historic buildings and places where proper humidity is hard to maintain. High humidity encourages mould and speeds up degradation of paper, wood, leather and textiles.

Consider room volume, pollution level, humidity, conservation requirements and expected operating intensity. Floor area alone is not enough. Describe your room and collection in the contact form — we'll help you choose the version and number of units.

Yes. The manufacturer names museums, libraries, archives, stores and exhibition spaces as its main areas of use. It also suits conservation studios, galleries and temporary exhibitions, where visitor traffic and display materials affect air quality.

It should not be treated as a way to remove active mould from object surfaces. Its job is to improve air quality and — in the DRY version — limit the excess humidity that favours mould. Objects with active growth need assessment and conservation treatment.

It can help maintain a proper environment after disinfection — a key use, since collections return to rooms where they should not meet the same threats again. It does not, however, remove ethylene oxide residues from objects or replace safe off-gassing and residue control procedures.

No. Treat it as part of a broader environmental strategy including proper ventilation, temperature and humidity control, and regular collection monitoring.

Yes. In 2021–2022 it was studied in the Fondazione Querini store in Venice — on the ground floor, by a wall directly bordering a canal. Baseline sampling took place on 20.12.2021, the unit was switched on on 20.01.2022, and air was sampled again on 24.02.2022 at four indoor points and one outdoor point.

At point 03, closest to the unit, total microbial load fell by about 69.7% (373 → 113 CFU/m³) and xerophilic fungi by about 94.1% (340 → 20 CFU/m³). Relative humidity on a selected sensor dropped from about 70% to 65% in the first hour and to about 58% later. The report also notes no significant improvement for bacteria. These are observations from one study, not a guarantee of identical results everywhere.

Ekofumigacja promotes technologies that reduce risks to people, collections and the environment. For decades biological threats were fought with substances such as ethylene oxide — a documented carcinogen. Our mission is to protect heritage not only when a threat appears, but above all to prevent it from arising.
