Ionizers are devices that use negative ions to remove small particles from the air, such as bacteria, viruses, and odors. This can help make the air appear fresher and cleaner, and may even benefit people with allergies or asthma. However, ionizers do not actually remove particles from circulation; instead, they charge them to attach to something else. Unless you constantly clean the hard and soft surfaces in your home, it becomes difficult to remove particles that have fallen to the floor. Recently, I changed all the air conditioning units in my house and installed air purifiers in each unit (3 in total), 2 on the main floor (about 3500 square feet) and one in the basement (1500 square feet).
These ionizers are on for 8 hours every day, and I have a Therapure TPP300D with UV+ ionizer that's on for 8 hours in my living room. To prevent my roommate from smoking second and third hand, I now plan to keep the ionizer on for 30 to 40 minutes when no one is in the room and then turn off the ionizer before anyone enters. Ionizer air purifiers are generally safe because they don't have enough energy to be harmful to your health. The frequency of nosocomial infections in British hospitals led the National Health Service (NHS) to investigate the efficacy of anions in purifying the air, and it found that repeated Acinetobacter infections transmitted through the air in a ward were eliminated by installing a negative air ionizer and the infection rate was reduced to zero, an unexpected result. Despite conflicting data related to ionizers, I usually leave the option turned off. Air ionizers are designed to help provide cleaner air by using ionized particles.
However, their effectiveness decreases with distance (even in ducts), so they are rarely used for this purpose and only for elements immediately adjacent to the actual ionizer. GPS markets a Neddlepoint bipolar ionizer for air conditioning applications with high levels of negative and positive ions, but with zero ozone emissions. This type of device is UL 2998 compliant, meaning it does not produce ozone. In conclusion, using an ionizer can be beneficial for your health as it can help reduce odors and make the air appear fresher. It can also help reduce nosocomial infections by eliminating Acinetobacter infections transmitted through the air. However, it is important to note that these devices do not actually remove particles from circulation; instead, they charge them to attach to something else.
Therefore, it is important to regularly clean hard and soft surfaces in your home if you want to ensure that all particles are removed.
