What is the Difference Between Negative Ion Air Purifier and HEPA Air Purifier?

Learn about how negative ion & HEPA Air Purifier work differently & which one is better for allergies & asthma.

What is the Difference Between Negative Ion Air Purifier and HEPA Air Purifier?

Ion purifiers have no filter and therefore do not effectively remove particles, especially the smallest and most dangerous ones. Its performance is much worse compared to a HEPA filter, and performance degrades as the plates get dirty. Negative ionizers are small devices that create a negative charge. This load allows the HEPA filter to capture more particles.

Ion generators come in different shapes and sizes, similar to that of a dental floss container. The main difference between air purifiers and ionizers is the way each device removes pollutants from the air. In the case of air purifiers, HEPA filters trap particles inside a filter, so it needs to be changed regularly. Ionizers don't have filters because they emit electrically charged particles to remove pollutants from the air.

It's important to understand that this doesn't completely remove those particles from the environment. The noise level is another characteristic to consider when comparing HEPA air purifiers and ionic air purifiers. HEPA air purifiers are designed to circulate air in the room and remove contaminants, dust, and allergens by trapping them in the filters. Unlike ionic purifiers, HEPA purifiers always use a fan; it is not possible for a product to work without it.

Ionic air purifiers usually lack a fan, so they are quiet. A HEPA air purifier works by drawing air into the device through a dense physical filter that traps air pollutants, such as dust, allergens, mold spores, bacteria, and smoke. 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 most common. An ionic air purifier without a filter works by sending electrically charged ions into the air that bind with harmful impurities. Ionizers don't use filters at all, and ionic air purifiers have metal collecting bars or plates that can be cleaned with a cloth. If you have asthma, allergies, or other respiratory conditions, a HEPA air purifier is more likely to alleviate your symptoms, as it prevents particles from re-entering the air you breathe.

If the HEPA filter is clogged, the air purifier fan will not be able to move air around the room to clean it. An air purifier uses physical filtration to capture particles from the air and prevent you from breathing them in. For an ionizer to be effective, it is necessary to dust or vacuum frequently, as pets and people walking around the room can cause particles to return to the air. That's what makes a HEPA filter the best air filter for allergies, the best air filter for asthma, and the best air filter for mold. Has specialized knowledge in the technology and design of air purification, air conditioning and heating systems.

Because a HEPA air purifier uses a physical filter, the maximum area it can cover is usually not as large as that of an ionizer. The main difference between ionic and HEPA air purifiers is that ionic purifiers use electricity to capture particulate matter, while HEPA purifiers use air filters to capture particulate matter. In fact, good HEPA air purifiers are almost always more expensive than ionizers and ionic air purifiers. Common standards require a HEPA air filter to remove at least 99.97% of particles whose diameter is greater than or equal to 0.3 μm from the air passing through the air. Air purifiers physically remove particles from the space, so you don't have to worry about vacuuming or removing dust, as there are no particles left on the floor that could return to the air.
