<\/p>\nOn a cool Athens evening, the smell of wood smoke can drift across balconies and through neighbourhood streets. Once you step indoors and close the door, it is easy to assume you have left the pollution behind.<\/p>\n
Yet some outdoor pollution can enter your home\u2014and everyday activities indoors can add to it.<\/p>\n
<\/p>\n
<\/p>\n
Fireplaces, wood stoves and traffic release gases and tiny airborne particles. These include PM2.5\u2014fine particles small enough to travel deep into the lungs.<\/p>\n
In October 2025, Kathimerini reported on international research<\/a> highlighting concerns about airborne particles in Athens. Researchers examined both the amount of pollution and properties that influence how harmful those particles can be.<\/p>\n The everyday message is simple: pollution deserves attention even when the air does not look dirty.<\/p>\n Outdoor particles can enter through windows, doors and small gaps around a building. Closing the windows during smoky periods can reduce their entry, but it does not make a home airtight.<\/p>\n Inside, cooking, tobacco smoke and candles can add particles. Cleaning products, paints and furnishings can release gases called volatile organic compounds (VOCs). Mold spores, dust-mite allergens and pet dander can also affect indoor air quality.<\/p>\n According to the US Environmental Protection Agency<\/a>, some indoor pollutants can reach levels two to five times higher than outdoors. This varies by pollutant, building and activity.<\/p>\n A clean-looking room is not necessarily a room with clean air.<\/p>\n During smoky periods, avoid leaving windows open unnecessarily. Ventilate when outdoor conditions improve, and use an extractor that vents outdoors when cooking.<\/p>\n Limit indoor smoke sources and maintain suitable air-treatment equipment. Particle filtration can help reduce airborne particles, while other technologies address particular gases and odor compounds.<\/p>\n Choosing equipment means looking at what it treats, its tested performance and whether it suits the room.<\/p>\n OH-Feel offers air-and-surface treatment systems in different sizes. Selected models combine hydroxyl technology with particle filtration to address different aspects of indoor pollution.<\/p>\n Particle removal and treatment of odor-causing compounds are different functions. The appropriate model depends on your space and the pollutants you want to address.<\/p>\n Explore the OH-Feel independent testing<\/a> to review the relevant model\u2019s results and test conditions.<\/p>\nPollution Comes From Outside\u2014and Inside<\/h2>\n
