Second-hand smoke has been proven to be more deadly since it enters the body of non-smokers without the filter of a cigarette. The particles associated with second-hand smoke can trigger asthma attacks and lead to cancer.
Air Purifiers used with High-Efficiency Particulate Air Filters (HEPA), or an IQAir filter has been shown to remove up to 99.9% of pollutants from the air. The Clean Air Delivery Rate (CADR) is used to evaluate the efficiency of the air purifier’s effectiveness. CADR is a figure of merit and is used to measure the actual number of pollutants removed per Cubic Feet per Minute (CFM) Here you can learn more about Hepa filters.
There are also Ionizing Purifiers. These air purifiers use what is called a corona discharge. A corona discharge creates ions. Ions are charged particles, which have a positive charge. Typically air particles are neutrally charged. Air Purifiers create a magnetic field that changes the neutrally charge air particles to positive. Within these Ionized Purifiers there is one negatively charged plate and one positive, now any particles in the air will be filtered out from their attraction to these plates.
