{"id":183,"count":20,"description":"HEPA air purifier - for pollutant-free breathing air\nHigh-performance air purifiers with HEPA filters remove a wide variety of pollutants from the air we breathe. This technology, which was originally developed for space travel, is now compact and inexpensive enough to ensure high air quality in private households as well.\n\n\"HEPA\" stands for \"High Efficiency Particulate Air\". The most powerful filter class, HEPA 14, has an efficiency of 99.995% and thus only allows a maximum of five out of 100,000 particles to pass. Modern air purifiers with HEPA filters clean the air we breathe extremely thoroughly, even in large rooms. Thanks to their sophisticated filter technology, these air purifiers catch even the finest particles in the air.\nWhat types of pollutants are captured by HEPA air purifiers?\nThe following types of particles and<strong> Pollutants<\/strong> are used by HEPA<strong> Air purifiers<\/strong> reliably removed from the room air:\n\nHouse dust and fine dust House dust mite excrement Pollen and animal hair Mold spores Bacteria and viruses Tobacco smoke, smog, gases and odors In order to filter out aerosols that can be smaller than 1 micron, we recommend air purifiers with activated carbon filters in addition to the HEPA filter. High quality air purifiers have three filters connected in series. A pre-filter removes large particles like cat hair from the air. The air is then passed through the HEPA fiber network. Tiny gas, smoke or virus particles that still penetrate are then neutralized by the activated carbon filter.\nHow do air purifiers work with HEPA filters?\nAn air purifier is equipped with one or more fans that guide the room air through the HEPA filter and, if necessary, other built-in filters. The cleaned air is then released into the room air.\n\nHEPA filters are so effective because they have an extremely large, irregular surface that is spread over up to 1,000 fine layers of synthetic fibers, glass fibers or cellulose. A complete HEPA filter mat filters particles with a diameter of only 0.0003 mm from the ambient air. In addition to the shielding effect of the individual filter layers, three other physical effects contribute to the efficiency of the HEPA filter mat:\n\n \t<strong>Barrier effect<\/strong> : The arrangement of many fiber layers creates a very irregularly shaped filter mat. This makes it extremely difficult for particles in the air to get through the narrow pores of the multi-layered fiber network. Sooner or later they stick to the surface of the filter fibers due to the adhesive force. This effect of HEPA filters is also known as trapping.\n \t<strong>Inertia effect<\/strong> : The inertia effect causes particles accelerated by a stream of air to move in the same direction until they are deflected or hit an obstacle. Inside the HEPA air filter, the air flow is swirled through the fiber network, whereby the particles in the air are forced by their own weight to follow the air flow until they stick to the filter fibers in the air cleaner.\n \t<strong>Diffusion effect<\/strong> : At the micro level, tiny particles move in a rather chaotic way and often collide with each other. This behavior is also influenced by heat and enables, among other things, the even mixing of liquids and gases. This effect is known as diffusion. In the HEPA filter, the chaotic movement of the particles causes them to quickly become entangled in the filter fabric. Air purifiers with HEPA filters offer the following advantages\n\nThe manufacturers are only allowed to use the designation HEPA for filters with a separation efficiency of at least 99.95%. At 99.995%, HEPA-14 filters are the most powerful filter class for air purifiers.\n\n \tExceptional filter performance of up to 99.995%,\n \tideal for allergy sufferers\n \tRelatively low acquisition costs\n \tEasy to change filters\n \tProven industry standard\n \tOzone free\n\n<strong>Air purifier with HEPA filters<\/strong> remove all harmful particles, from animal hair to house dust to tobacco smoke and even the smallest bacteria and viruses that float in the air as aerosols. We recommend using disposable filters as used reusable filters are very difficult to clean and lose their performance over time.<strong> Replacement filter<\/strong> for air purifiers are inexpensive and easy to change. Newer devices are even equipped with sensors that tell you when it is time to change the HEPA filter. Since the degree of soiling can vary from device to device, we recommend replacing the filters every six to twelve months.\nTop-class HEPA air purifiers - our recommendation\nAn air purifier with a HEPA filter protects you from contamination in the room air. Keep the air you breathe in your home, office, business, or other location<strong> Allergens, dust, mold spores, viruses and bacteria<\/strong> . Opt for the top models to eliminate unpleasant odors or tobacco smoke at the same time and ensure maximum air exchange with minimum operating noise.
