A Smoke Free World

Designed with both smokers and non-smokers in mind, the Spiro system aims to provide a quick use shelter for those who want to smoke without disturbing others. Its high tech filtration system and functional shape create an invisible curtain around the user, preventing second-hand smoke from entering public areas. Without walls, it’s easier to move in and out of and makes responsible smoking less of a chore for those who enjoy their ciggies. 

Spiro’s unique filtration system cleans the air with polarized media filter technology, which consists of a flexible activated carbon foam material at its base that works as a conductor for static electricity generated in the plastic fiber material on both sides. The carbon connects to powerheads in the air cleaner, where, under current, the plastic fiber material is charged , sucking bigger pollutants into itself from the passing air while the carbon neutralizes VOCs, harmful chemicals, smoke and odors.

The plastic fibers in the filter of Spiro Air Cleaners are cellulose acetate recycled from discarded cigarette butts processed through autoclaving and chemical treatment. This way, 95% material purity can be reached.  The outdoor version has an ashtray to collect butts and ashes in the smoking area, like any other smoking shelter. An estimated 1.7 billion pounds per year is “wasted” from cellulose acetate by throwing it away in the shape of filters. It biodegrades very slowly, staying in nature with toxic chemicals seeping from the filters into water and soil.  

The outdoor configuration of Spiro is an umbrella like folding shelter. It affords site-specific air cleaning where passive smoke is a problem in public areas, preventing it from moving into non-smoking areas by creating an air curtain around the perimeter of the umbrella. Because no walls are used, the space under the shelter is unobstructed as the single leg takes up little space. This allows users to move freely in and out of the umbrella. 

Easy opening and closing of the umbrella is done by an inflatable rim under the arms, which is operated by a radial compressor connected to the air intake fan. The indoor configuration provides a versatile solution for indoor air filtering and can be mounted on the ceiling or as a standalone object. It circulates the air in the room by moving the air along the ceiling which then moves down the walls, pushing air at the floor upwards. Both variations have a lighting function with a dimmable LED light shell to be used at home as ceiling light or outdoor lighting.

    “Its high tech filtration system and functional shape create an invisible curtain around the user.” Do tell: what is this magic?

  • Csaba says:

    It uses only widely applied, existing technologies. That’s an air curtain, and the user stands in the area that it closes inside from the surrounding air. The correct info is on the corresponding slide about it.

  • What a great thing! Thank you, Csaba Kálmán!

    Hi Csaba,

    Would you please give me your contact info so that we could talk about the business opportunities in Asian market?

  • Hello, I am very interested in this idea and have been trying desperately to find out more, as we have a problem of smoke from our outdoor smoking area re-entering the offices via open windows. But, of four websites I’ve found giving product détails, not one gives contact détails! I see others have requested such information and received no response. So please excuse me contacting you this way via a conversation with someone else.
    Please can you tell us where we can obtain commercial information (price, delivery) for this product?
    Best regards.
