When looking for the Best Air Purifier, or more specifically the Best Ionic Air Purifier, people probably want a silent air purifier that destroys mold spores and organic allergens among other things, and the AirFree P3000 filterless air purifier may be that purifier.\r\n\r\nWhy We Like It - AirFree P3000\r\nThe AirFree P3000 has an award-winning design that doesn\u2019t require a filter or a fan, and can use heat to provide clean air without making any noise. It can capture various contaminants, and has simple controls, all while having the appearance of chic and modern home decor.\r\n\r\nPower\/speed\r\nWhat it lacks in a filter, a UV light, or a fan, it makes up for with design, lack of noise, and low energy consumption. Due to having thermodynamic TSS technology, Airfree air purifiers still manage to be part air sterilizer, part filter, and more. Unlike the AeroMax 300, which uses a 4 stage filter, the AireFree air purifier uses heat to eradicate pollutants such as a dust mite to improve the overall air quality.\r\nEfficiency(room size etc.)\r\nFor such a small purifier, it has a surprisingly wide range. It has an area coverage of 650 square feet, surpassing the Pure Enrichment air purifier filter, which has the area coverage of 190 square feet. It\u2019s easy to move from room to room, and can be used for larger rooms without making any noise as it gets rid of any airborne microorganisms. It also has an adjustable night light for when the user needs to roam the room at night.\r\nVersatility (HEPA, what does it filter, odor reduction etc.)\r\nThe Airfree Onix air purifiers don\u2019t contain HEPA filters, or any filter for that matter. Instead, it contains filterless technology, in the form of the manufacturer\u2019s exclusive patented thermodynamic TSS technology. Because of this, it can capture mold, dust mites, bacteria, viruses, pollens, and pet dander through the ceramic core, using heat to destroy the organic pollutants.\r\nDurability\r\nThe AirFree unit has the appearance of home decor to help blend in with the decor that the user already has, and, unfortunately it has the durability of some home decor as well. The housing is made of plastic to house the ceramic core, similarly to the Silveronyx air purifier with true HEPA filter, except it has a filter instead of a ceramic core filter. However, it\u2019s also very light weight, as it weighs 3.1 Lbs., weighing less than the Silveronyx, which weighs 5.39 Lbs.\r\nValue\r\nDespite its small size, it\u2019s expensive due to the parts and design it has in spite of its simplicity. The thermodynamic TSS technology and everything that it\u2019s made of, such as the ceramic core, are what affects the cost the most. It takes a completely different approach to air purification instead of just using a filter, which while effective and convenient, also means that if any breaks, the whole purifier would have to be replaced.\r\nAirFree P3000 Wrap Up\r\nCustomer reviews have been mostly positive, praising the purifier\u2019s performance. It garnered a big enough reputation to be featured in a video for related products on Amazon.com. One reviewer addressed how it\u2019s effective for mold and mildew in closets, and that it completely got rid of the smell after a year.
