As you learned, a HEPA air purifier can be more efficient at removing air contaminants because it actually traps particles inside a physical filter. An ionizer, on the other hand, doesn't remove contaminants, but instead causes them to come out of the air you breathe. To improve air cleaning performance, HEPA air filters are the best technology. They remove most airborne contaminants, as well as the most dangerous particles.
In addition, HEPA filters become more efficient over time. Which means they eliminate more with use. The main difference between an ionic air purifier and a HEPA air purifier is that electrostatic collector plates can be washed and reused as they become dirty. If you have asthma, allergies, or other respiratory conditions, a HEPA air purifier is more likely to relieve symptoms because it prevents particles from re-entering the air than you breathe.
However, an air disinfectant with UV light doesn't filter particles from the air, so it won't help if you have allergies. Ozone air purification is sold only as a commercial air purifier, as the state of California does not allow them to be sold to consumers. The main difference between ionic and HEPA air purifiers is that ionic purifiers use electricity to capture particles, while HEPA purifiers use air filters to capture particles. That's why a HEPA filter is the best air filter for allergies, the best air filter for asthma, and the best air filter for mold.
And they don't let particles pass through them either: HEPA filters are capable of capturing 99.97% of 0.3 micron diameter particles. Other brands call their filters with names such as HEPA-type filters or a marketing term with HEPA added. If you're wondering if HEPA filters will let more particles through as they get dirty, don't worry. While beneficial from a cost standpoint, a lot is lost in performance compared to a HEPA filterThis is because an ionic air purifier requires a fan to draw air through the system and the electrostatic collection rods can only be so large.
The main difference between air purifiers and ionizers is the way each device removes contaminants from the air. When it comes to an ionic air purifier versus a HEPA air purifier, the ionic air purifier works in a similar way to a HEPA air purifier, but uses electrical charging plates to collect contaminants. If you're looking for an air purifier for your home, you might be confused by the different types: ionic and HEPA air purifiers are the more common. HEPA air purifiers have a limited coverage area; most cannot cover an area of more than 2000 square meters.
