When looking for the Best Air Purifier, or more specifically the Best Ionic Air Purifier, people probably want something that has an impressive area coverage, and the Mammoth air purifier may be such a purifier. It also has a lot of speed options for both the fan and ozone generator.\r\n\r\nWhy We Like It - Mammoth Air Purifier\r\nThe Mammoth air purifier has an incredible area coverage range, a very simple control system in the form of 2 knobs, and it comes with a 1 year warranty. It doesn\u2019t have a soldered in power cord, so if there\u2019s any damage to the cord, it can easily be replaced.\r\n\r\nPower\/speed-\r\nWhat makes air purifiers such as this one stand out is a feature known as an Ozone generator. The generator produces ozone air that exits the ozone plates located on the back of the purifier. In addition, users have the option to adjust the fan\u2019s speed, with 10 speeds to choose from, unlike the Aeramax 300, which only has 3 speeds. The ozone generator also has 10 output settings for Ozone level.\r\nEfficiency(room size etc.)-\r\nThis air purifier has an area coverage of 3,500 square feet at the most when both the fan and the ozone generator are used at the same time, surpassing the Silveronyx air purifier with true hepa filter, which has an area coverage of 500 square feet. Fresh air can easily be distributed in a large house, or even a workplace, because of the Mammoth purifier\u2019s option of having an adjustable fan speed as well as an adjustable generator output.\r\nVersatility (HEPA, what does it filter, odor reduction etc.)-\r\nWhile it doesn\u2019t use a HEPA filter, it has the ability to filter through a variety of air contaminants. It captures mildew, mold, smoke, odors such as food and pet-related smells, and certain viruses and bacteria. Both the Mammoth and the Pure Enrichment air purifier filter can be used to kill microorganisms that can cause illnesses using radically different methods, but the Pure Enrichment air purifier can\u2019t be used to filter mildew.\r\nDurability-\r\nThe purifier weighs 14.42 Lbs., which can be mainly contributed by the ozone system, the fan, and the sturdy wooden encasing. Since it\u2019s an air purifier, it will inevitably have weak points to allow the air to travel through it in order to be filtered. However, only the side where the air goes in is vulnerable. The side where the air goes out has a metal plate with much smaller holes to offer protection while allowing the air to exit.\r\nValue-\r\nWhile it has a very simplistic way for the user to operate the purifier, there\u2019s a lot that the machine can do despite the simplified controls and simple appearance. What mainly contributes to the overall cost of the purifier are the Ozone generator, the fan and ionizer, and the ceramic ozone plates. Keep in mind that the ozone plates should be treated like filters should be washed every once in a while.\r\nMammoth Air Purifier Wrap Up\r\nCustomer reviews from the United States have mostly been positive, praising the verified purchase for its fast performance. One reviewer addressed that the area should be closed off if the ozone generating feature is in use. Customers should remember to check the product information, as there are a couple of things you should do before using it.
