It works by replicating natural atmospheric processes to neutralize odors, bacteria, viruses, mold, and harmful pollutants\u2014without the need for filters or chemicals.<\/p>\n<p data-start=\"766\" data-end=\"937\">Below are answers to the most common questions about how hydroxyl generators work, their safety, and why they are more effective than traditional air purification systems.<\/p>\n<h2><strong>What are hydroxyl radicals and how do they work indoors?<\/strong><\/h2>\n<p>Hydroxyl technology is designed to help reduce a wide range of indoor contaminants in both the air and on exposed surfaces, including:<\/p>\n<ul>\n<li>Airborne bacteria and viruses<\/li>\n<li>Surface-associated microorganisms and residues<\/li>\n<li>Mold spores and mold-related odors<\/li>\n<li>Smoke and persistent vehicle or cabin odors<\/li>\n<li>Allergens such as pollen, dust mite particles, and pet dander<\/li>\n<li>Volatile Organic Compounds (VOCs) and Total VOCs (TVOCs)<\/li>\n<li>Certain oxidizable gases such as formaldehyde, ammonia, and nitrogen dioxide<\/li>\n<\/ul>\n<p>Hydroxyl radicals disperse throughout the space and react extremely quickly \u2014 often within milliseconds \u2014 breaking down pollutants and odor-causing compounds wherever contact occurs.<\/p>\n<h2><strong>How do hydroxyls clean surfaces and hard-to-reach places?<\/strong><\/h2>\n<p>Traditional air purifiers require air to pass directly through the unit to be filtered. Hydroxyl systems operate differently.<\/p>\n<p>Hydroxyl radicals are dispersed into the surrounding air, allowing them to circulate naturally throughout the room. This enables interaction with contaminants in areas that air filters may not effectively reach, including:<\/p>\n<ul>\n<li>Surfaces<\/li>\n<li>Fabrics<\/li>\n<li>Corners and enclosed spaces<\/li>\n<li>Air that does not directly pass through a filter<\/li>\n<\/ul>\n<p>Because hydroxyl radicals are highly reactive and short-lived, they act on contaminants where contact occurs, rather than relying solely on air circulation through a device.<\/p>\n<h2 data-start=\"766\" data-end=\"937\"><strong>Where can OH-Feel hydroxyl generators be used?<\/strong><\/h2>\n<p data-start=\"766\" data-end=\"937\">OH-Feel systems can be used in homes, offices, cars, boats, clinics, gyms, and any indoor environment where clean air and odor control are important. They are especially effective in enclosed spaces where odors and contaminants tend to build up.<\/p>\n<h2><strong>How Do Hydroxyls Eliminate Mold and Mold Odors?<\/strong><\/h2>\n<p>Hydroxyls are highly reactive molecules that kill mold by stripping electrons from its cellular structure, a process known as oxidation. This &#8220;molecular attack&#8221; punctures the protective cell walls of mold spores, deactivating them and preventing any further reproduction or growth. Because hydroxyls mimic a natural atmospheric process, they safely hunt down mold in both the air and porous surfaces without the need for harsh chemicals.<\/p>\n<h2><strong>How fast does the OH-Feel system start working?<\/strong><\/h2>\n<p>The system starts producing hydroxyl radicals as soon as it is activated. The improvement in odors and air freshness can be noticed in a short period of time, depending on the level of pollution, ventilation and the size of the space.<\/p>\n<p>In highly polluted environments \u2013 such as strong smoke odours or enclosed boat cabins \u2013 a more intensive decontamination phase may be applied initially.<\/p>\n<p>However, hydroxyl technology is most effective when used as a continuous air quality management system.<\/p>\n<h2><strong>Are hydroxyl generators safe for people, pets, and plants?<\/strong><\/h2>\n<p>Hydroxyl radicals occur naturally in outdoor air and are part of Earth\u2019s normal atmospheric chemistry.<\/p>\n<p>OH-Feel systems are designed to generate controlled levels appropriate for occupied indoor environments. Independent third-party testing has evaluated performance and safety under laboratory conditions.<\/p>\n<p>As with any air quality technology, proper use according to manufacturer guidelines is important.<\/p>\n<p>OH-Feel systems have been tested by independent laboratories under controlled conditions.<\/p>\n<h2><strong>Can hydroxyls remove smoke and vehicle\/car odors?<\/strong><\/h2>\n<p>Yes. Hydroxyl radicals are particularly effective in oxidizing odor-causing organic molecules, such as:<\/p>\n<ul>\n<li>Cigarette smoke<\/li>\n<li>Cooking odors<\/li>\n<li>Pet odors<\/li>\n<li>Musty cabin smells<\/li>\n<li>Persistent vehicle interior odors<\/li>\n<\/ul>\n<p>Because hydroxyls interact directly with odor-causing compounds rather than masking them, they help break down the source of the smell rather than covering it with fragrance.<\/p>\n<h2><strong>Will the contaminants come back after use?<\/strong><\/h2>\n<p>The interiors are dynamic. People, pets, materials and outdoor air are constantly introducing new pollutants.<\/p>\n<p>If the original source remains (moisture, smoke, etc.), contaminants may reappear. For this reason, hydroxyl systems work best as continuous use maintenance systems.<\/p>\n<h2><strong>How does hydroxyl purification differ from traditional air filters?<\/strong><\/h2>\n<p>Most conventional air purification technologies \u2014 including HEPA, electrostatic filters, and certain UV-based systems \u2014 rely on pulling air through a device to capture particles.<\/p>\n<p>Limitations of filter-based systems can include:<\/p>\n<ul>\n<li>Only cleaning air that passes through the unit<\/li>\n<li>Limited effectiveness against gaseous pollutants<\/li>\n<li>Recontamination as filtered air mixes with untreated air<\/li>\n<li>Surfaces are not sanitized<\/li>\n<\/ul>\n<p>Hydroxyl technology differs because it disperses reactive molecules into the environment, allowing interaction with contaminants in the air and on surfaces \u2014 not only within the device itself.<\/p>\n<p>Rather than passive filtration, it supports active oxidation of many organic pollutants.<\/p>\n<p>This is why hydroxyl technology provides a more complete solution than traditional air purification systems.<\/p>\n<h2><strong>Should hydroxyl systems be used continuously?<\/strong><\/h2>\n<p>In most residential, commercial, marine, and vehicle applications, hydroxyl systems are designed for ongoing use.<\/p>\n<p>Rather than functioning as a one-time treatment, hydroxyl technology supports continuous air and surface management. Operating the system regularly helps:<\/p>\n<ul>\n<li>Manage newly introduced airborne contaminants<\/li>\n<li>Reduce recurring odors<\/li>\n<li>Support surface cleanliness<\/li>\n<li>Maintain stable indoor air quality<\/li>\n<\/ul>\n<p>In specialized situations \u2014 such as severe odor remediation or seasonal boat cabin treatment \u2014 an initial higher-density treatment phase may be required,\u00a0 followed by long-term maintenance at standard operating levels.<\/p>\n<p>This two-phase approach \u2014 remediation followed by maintenance \u2014 provides both corrective and preventive benefits.<\/p>\n<h2><strong>What independent testing supports hydroxyl technology?<\/strong><\/h2>\n<p>OH-Feel systems have undergone independent laboratory evaluation under controlled environmental conditions.<\/p>\n<p>Documented testing has demonstrated significant reduction of specific airborne and surface microorganisms. Laboratory results have reported reductions of\u00a0<strong>99%+ for certain tested organisms, including human coronavirus strains and Staphylococcus albus<\/strong>, within defined exposure times and chamber conditions.<\/p>\n<p>Performance varies depending on model, exposure duration, room size, and environmental factors. Full laboratory reports, detailed methodologies, and organism-specific reduction data are available in the\u00a0<a href=\"https:\/\/ohfeel.gr\/test-results\/\"><strong>Test Results<\/strong><\/a>\u00a0section for transparency and review.<\/p>\n<h2><strong>1\ufe0f<\/strong><strong>\u20e3 Maintenance &amp; Upkeep<\/strong><\/h2>\n<p><strong>What is the maintenance schedule for an OH-Feel system?<\/strong><\/p>\n<p>Our systems are designed for low-maintenance, industrial-grade reliability. The primary requirement is replacing the specialized UV optics (the hydroxyl-generating lamps), typically every 8,000 to 9,000 hours of use (approximately once per year if run 24\/7). The QTV1 and FC08A models (30 SQM coverage) have washable filters that should be replaced once a year at minimal cost. The CZ02 model (10 sqm) used in small rooms and cars has no filter to replace. The larger 500 series (60 -120 sqm) have washable and replacement filters.<\/p>\n<h2><strong>2\ufe0f<\/strong><strong>\u20e3 Energy Consumption<\/strong><\/h2>\n<p><strong>How much electricity does the unit use? Can I leave it on 24\/7?<\/strong><\/p>\n<p>Yes, OH-Feel is designed for continuous operation. Most of our portable units consume less energy than a standard 60-watt light bulb. This allows you to maintain air and surface sanitization around the clock without a significant impact on your utility bill.<\/p>\n<h2><strong>3\ufe0f<\/strong><strong>\u20e3 Noise Levels<\/strong><\/h2>\n<p><strong>Is the system loud? Can it be used in a bedroom or quiet office?<\/strong><\/p>\n<p>Our residential and office models are engineered with high-efficiency, low-decibel fans. On standard settings, the sound is comparable to a quiet computer fan or a gentle white-noise machine, making it ideal for bedrooms, clinical treatment rooms, and professional workspaces.<\/p>\n<h2><strong>4\ufe0f<\/strong><strong>\u20e3 Ozone Safety<\/strong><\/h2>\n<p><strong>I\u2019ve heard that &#8220;activated oxygen&#8221; or ozone can be harmful. Is this an ozone generator?<\/strong><\/p>\n<p>No. While ozone generators require the room to be empty because ozone is a lung irritant, OH-Feel uses a different molecular process. Our technology creates hydroxyl radicals, the same molecules that clean the Earth\u2019s atmosphere every day. OH-Feel systems are strictly tested to ensure ozone emissions stay well below recognized safety thresholds, (such as those set by OSHA and the FDA),\u00a0 making them safe for use in occupied spaces.<\/p>\n<h2><strong>5\ufe0f<\/strong><strong>\u20e3 Placement for Best Results<\/strong><\/h2>\n<p><strong>Where is the best place to position my OH-Feel unit?<\/strong><\/p>\n<p>For maximum effectiveness, place the unit in a location with good natural airflow, away from corners or obstructions. Since hydroxyls disperse like a gas, the unit works best when it can circulate freely. In multi-room spaces, placing the unit near a return air vent or a central hallway helps distribute hydroxyls throughout the environment.<\/p>\n<h2><strong>Ready to Experience Cleaner Air?<\/strong><\/h2>\n<p>If you are tired of odors, stale air, or concerns about indoor air quality, OH-Feel hydroxyl technology offers a proven, science-backed solution that works continuously in your space.<\/p>\n<div class=\"row\"  id=\"row-1605083483\">\n\n\t<div id=\"col-12669769\" class=\"col medium-6 small-12 large-6\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\t<a id=\"btn-2595493919\" href=\"https:\/\/ohfeel.gr\/en\/contact-us\/\" class=\"button primary\" >\n                        <span>Contact Us<\/span>            \t<\/a>\n    \t\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n\n\t<div id=\"col-1594291759\" class=\"col medium-6 small-12 large-6\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\t<a id=\"btn-2619039621\" href=\"https:\/\/ohfeel.gr\/en\/shop\/\" class=\"button primary\" >\n                        <span>Shop OH-Feel Units<\/span>            \t<\/a>\n    \t\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>\ud83d\udcd8Hydroxyl Technology FAQ \u2013 How It Works, Safety &amp; Benefits Hydroxyl technology is one of the most advanced air and surface purification methods available today.
