Best Ion Air Purifiers

Choosing any kind of air purifier isn’t easy. There’s a lot of choice out there after all. Don’t worry though, as we’ve done all the hard work for you. Not only will we be looking at the benefits and uses of an air purifier ionizer, but we’ll also look at what we consider to be the best choice for this type of air cleaner.

What are Negative Ions – And How Does an Ionizer Air Purifier Help?

Air ionizers work by electrically charging molecules in the air. Most traditional air purifiers use True HEPA filters and fans to eliminate the contaminants in the air. The best air ionizer will instead use ions.

Air ionizers are powered by the chemical properties of ions. Ions are particles that have either a positive or a negative charge. An air ionizer essentially creates negative ions and sends them out into the air. The negative ions attach to positively charged particles like dust, pollen, and bacteria. The negative and positive ions bond together and create a dense dirt particle that is too heavy to float in the air. These heavy particles drop to the ground and can be removed through dusting and other cleaning methods. Negative ions are thought to offer several air ionizer benefits, which we’ll get to now.

Ionizer Air Purifier Side Effects

Negative Ions Freshen and Purify the Air

An ionizer air purifier is able to make allergens such as pet dander and pollen stick to each other and form clumps. The clumps are too heavy to float so they drop to the ground. This is something that can be included in the list of HEPA air purifier side effects but what separates ionizers is that they can do it all without a filter.

 Kill Germs in the Air

Research has shown that the negative ions given out by an ionizer have a bactericidal effect (kills bacteria) in the air. So the air you breathe is healthier as well as cleaner.


Negative ions have been shown to improve mood and offer relief for depression. Some institutions actually use negative ions as part of their treatments for depression, which should give you an idea of how potent this effect can be. Even the professionals swear by it.

Doesn’t Stir Up Dust

Unlike fan-based true HEPA air filters, these ionizer air purifiers don’t stir up the dust on the floor or on tables. Rooms that have one of these ionizers can become free from dust and other problems because it is all dragged down to the ground and easily swept away.

Now that we know some of the best air ionizer benefits let’s take a look at the Air Oasis 1000G3; one of the best machines in this category.
