Anti-pollution trickle vent

We are the first company to introduce filtration in the most popular ventilation system.


Anti-smog air intake

Our anti-pollution trickle vent is a simple solution that protects your home against harmful air-borne contaminants and allergens. That small device provided with a replaceable air filter considerably reduces the flow of particles such as suspended particulate matters PM10 and PM2.5, coal, cement and industrial dusts, plant pollens and spores as well as mites and large bacteria.

Which filters do we use?

For Insolio and Urbino trickle vents, we use progressive filters. This means that the layers of polyester fibres of various thickness values are arranged in such a way that the filter density increases in the direction of air flow. Such a filter absorbs up to 99% of PM10 and up to 80% of PM2.5, as well as allergens that are so irritating in spring and summer.

We recommend filter replacement twice a year. It is preferred to do it before and after the heating season. The replacement is very intuitive, a new filter can be installed in just four movements.


Anti-smog trickle vent

A bit of theory

In Poland, the standards for PM10 are as follows:

• 40 µg/m3 – admissible average annual concentration
• 50 µg/m3 – admissible average daily concentration (which may be exceeded no more than 35 times per year)
• 200 µg/m3 – notification level for average daily concentration
• 300 µg/m3 – alarm level for average daily concentration

To make a comparison, the standards recommended by the World Health Organisation (WHO) are 20 µg/m3 for average annual concentration and 50 µg/m3 for average daily concentration. For PM2.5, Poland has only set the admissible average annual concentration, which is 25 µg/m3.

Although the admissible daily concentration for PM10 may only be exceeded 35 per year, many Polish cities exceed it on even 100 days. During that time, the concentration of contaminants can be above 200 µg/m3 or even 300 µg/m3 or more.

Then how do we benefit from an anti-smog filter? Even if the PM10 concentration level outside exceeds the alarm value of 300 µg/m3 (600%), the air inside the house will remain within the limits. At the same time, the room will continuously receive an optimum amount of oxygen, and the ventilation system will work properly by eliminating any surplus carbon dioxide and preventing excessive moisture accumulation.

In winter, when we spend most time in enclosed rooms, ventilation and air cleaning in those rooms are very important, especially if they are regularly used by pregnant women, children, the elderly or people suffering from heart or lung diseases. Even preliminary filtration in the ventilation system is a significant release to those who are particularly sensitive to the toxic effects of smog.

Allies against smog

An anti-smog trickle vent is also a great support for in-house air purifiers and toxin-absorbing plants. A purifier is supposed to filter the air in the room, and the trickle vent filters the air before it enters the purifier. Since the purifier needs some time to clean the air to the target level, filtration in the vent system significantly accelerates its operation. This is especially because the trickle vent filters 100% of the air that enters the room.
