The SPT Magic Clean 2-Speed 100-sq-ft Ionic Non-HEPA Air Purifier is an air purifier that uses ionic technology to remove pollutants from the air. It has two fan speeds and can purify a space of up to 100 square feet. The air purifier works by emitting negative ions, which attach themselves to positively charged pollutants, such as dust, pollen, and pet dander. These pollutants are then attracted to the purifier's filter and trapped. The SPT Magic Clean 2-Speed 100-sq-ft Ionic Non-HEPA Air Purifier is a good option for people who are looking for an affordable air purifier that can remove basic pollutants from the air. However, it is not as effective as HEPA air purifiers at removing small particles, such as viruses and bacteria.
