Best Rated Negative Ion Generators

Having a negative ion generator inside is like breathing the fresh air outside in nature.

Get a Total Well-Being Upgrade

Aside from getting out in nature near waterfalls and beaches, the best way to get negative ions in your home is through a negative ion generator. Here’s a list of the best rated negative ion generators and a short guide on what to look for to determine the best choice for you.

Negative ions are “the vitamins of the air” and they make you feel overall better. Capable of cleaning the air by attaching to harmful airborne particles like dust, dander, pollen, and more to drag them down onto the ground or surfaces so you don’t have to breathe them in. These ions also are associated with POSITIVE effects on your overall well sense of being…everything from improved breathing and focus to lower stress and susceptibility to illness.

What To Look For

1. Square Foot Area Coverage –

You’ll want to know how big of a room you will want your ionizer to work in and the rough estimate of its square feet area. Lucky for you I’ve organized the negative ion generators on this list from lowest to highest in terms of square feet area reach so you can quickly scan and narrow down your options from a list of great recommended units.

Having a unit with a smaller reach in a large room that cannot clean all the air can be just as ineffective as having a unit with a very large reach in a small room which can be overkill in air cleanliness and possibly cause headaches/faintness.

So it’s important to have an idea of a size range you’re looking for and choose accordingly. This will save you time, money, and energy…of your house and your body.

2. Negative Ion Output –

The more the merrier is what you’ll want to err on the side of. More negative ions will typically give you more of the fresher feeling that you would experience on a beach or by a waterfall or just being surrounded by nature.

Just keep in mind the stronger the output of negative ions the more carefully you will have to place your unit in relation to electronic devices, pets, children, and where people usually hang around in the room. This is a safety precaution so no one or nothing is being directly overloaded with super clean air which can be initially nauseating and/or harmful.

Another small thing to keep in mind…high negative output is important but typically the farther you get away from any given unit the less negative ions are being emitted. This is known as ion density and it’s not as commonly listed because it’s harder to measure but some companies do go out of their way to list them.

Be on the lookout for it and if you read reviews of customers sometimes they measure and report this information themselves

3. Ozone Option –

Now, I want you to know the difference between negative ions and ozone. Read here to know all the different air cleaning methods.

Negative ions are groups of oxygen atoms with extra electrons that usually promoted better well-being while ozone is a volatile group of oxygen atoms (H3) that change the molecular structure of other airborne particles.

Negative ions are good for your health while ozone is very AGGRESSIVE air cleaning that should NOT be breathed in directly but used sparingly in your absence because it is known to be harmful to your health.

Sometimes marketers use the term “ionic” or “ionizer” to mask the fact that a product is really using ozone. BE CAREFUL when you are conduction your own research and read the info and reviews to truly know what is being offered.

The items on this list have optional ozone functions that can be used as extra air cleaning when you leave your home or office so by the time you get back all odors and irritants will be eliminated or greatly reduced which leaves it smelling fresh.
