Benefits of using a negative ionizer

5 Most Effective Negative Ion Generators – Fresh Air Every Day!

There is a number of reasons why you should use a negative ionizer. First, you will not be able to see the particles that float around in the air because they are so fine in size, but these contaminants can lead to health problems such as heart and lung diseases and further make asthma and bronchitis worse for people.

Negative ionizers help to purify the air of these contaminants and produce higher quality air. For those that also suffer from allergies, negative ionizers can help remove matters such as pollen from the air. Negative ionizers are also great for helping to fight off any bad odor that may be lingering in your air. Especially if you cook a lot of have pets whose odors sit in the fabric of your furniture, negative ionizers is great at minimizing these odors.

Breathing fresh and safe air should be available to all people, and depending on where you live, clean air can be a problem. However, with a negative ionizer in your household, you will be able to enjoy the benefits of fresh air every day.

How to pick the best negative ion generator?

When choosing the best negative ion generator, it depends on what it is you’re looking for in a particular model. If you’re unsure of what features to focus on, you’re in the right place. Here, we’ll be taking you through the most important individual features of negative ionizers to help inform you more about these devices. Some of the things we’ll cover include the coverage area, efficiency, modes and settings, design, noise level, dimensions, and weight, and finally, the price of these units. All of these features work together to create a negative ionizer that makes it the best in its class.

What is it recommended against?

The one thing people may not know about is that there are lots of different contaminants that can be harmful to you. Fortunately, the best negative ion generators are able to work against plenty of these bad particles. While each negative ion generator is different, we can see some similarities between them. These negative ionizers are recommended against smoke and different odors, allergens such as pollen and dust, mold, and airborne bacteria. If you are looking for a model that works well against various contaminants, check the Dreval D-903 Air Purifier.

Coverage area

This refers to the amount of space in the room that the negative ion generator can cover effectively. Since these products are made by different companies and are of different sizes, the coverage area will naturally be different for each product. For example, the Wein Vortex VI-3500 Room Ionic Air Purifier has a coverage area of 800 square feet, which is large enough to purify the air in most two-bedroom apartments or a very large living and dining room. On the other end, our Editor’s Choice, the TREKOO Air Purifier, is capable of purifying the air in the 166 square feet room.

While the coverage area is crucial, the efficiency of the dispersion of negative ions per second, filtration stages, and different modes are just as important.

Efficiency

The best negative ion generators are great for their efficiency. The efficiency of these devices is determined by how many negative ions are released into the air per second. It should be important to note the way that negative ions work.

Negative ions are released into the air from your generator, and they clamp on to the particulate matter in the air, and instead of eliminating them, much like how air purifiers do, they latch onto these fine particulate and drag them to the floor. The particulate is still on the floor, and you’ll need to either vacuum or do a deep cleaning to remove it. The best negative ionizers do a great job of releasing millions of negative ions into the air, and the more of these release, the better all of the particulate matter in the air will be caught and dragged down to the surface, which leads to cleaner air for you.

Modes and settings

5 Most Effective Negative Ion Generators – Fresh Air Every Day!

The best negative ion generators all vary when it comes to modes and settings. Some of these generators have a timer function that enables you to use your negative ionizer only during certain times of the day. This can help you save up on electricity and reduce the wear and tear of the device. Some models, like our Editor’s Choice, the TREKOO Air Purifier, come with a variety of modes that allow you to change them accordingly to your needs. For example, you may want to turn down the efficiency in ‘toilet’ mode as opposed to ‘sleep’ mode.

Design

In terms of the design of the best negative ion generators, for the most part, they are very small, and they have fairly intuitive interfaces. This means that you can easily learn how to use the unit quickly since there are very few things to interact with on the product. For some negative ionizers, like the IonPacific Ionbox, there is actually nothing to engage with as you simply plug it into the wall and press the power button to work it.

On the other hand, the Dreval D-903 Air Purifier and the TREKOO Air Purifier both have intuitive controls on them it, and it’s quite easy to learn how to use both. Some have preset timer modes as well that you can utilize if you only want to use it for a few hours at a time.

Noise level

Nothing can be more annoying than a negative ion generator that makes constant and loud noises as it’s working. Fortunately, the best negative ion generators are all fairly quiet when they are operating. Some, like our Editor’s Choice, the TREKOO Air Purifier, even have their own quiet operation modes. Others negative ion generators, however, have large fans, and these tend to be much noisier.

It’s advised to always check the noise levels of the negative ion generator before purchasing it.

Dimensions

For the most part, the best negative ion generators are fairly small, and some, including our Best Portable Negative Ion Generator, the IonPacific Ionbox, are so tiny that you can easily pack them up and bring with you on vacation. This one only measures out to 6 inches by 4 inches, so you can imagine, fitting this ionizer into the palm of your hand. The other ones are also quite small, with the biggest one being the Dreval D-903 Air Purifier, which only measures out to 13 inches wide and 20 inches tall.

Weight

Much like the rather small dimensions of these negative ion generators, the weight of these devices is fairly low as well. Some are as light as just one pound, such as seen with the Nature Bright SunTouch Plus, while others can weigh a bit more. The heaviest negative ion generator in our list is the Dreval D-903 Air Purifier, which weighs 11 pounds.

Extra features

5 Most Effective Negative Ion Generators – Fresh Air Every Day!

The best negative ion generators are fairly straightforward, and very few of them really offer any extra standout features. Some of the best negative ion generators offer a motion detector feature that is able to register whether there are people in the room. The more motions it sees, the more it will continue to run, and when there is no motion, it will reduce energy consumption. Another extra feature is actually a big part of the Nature Bright SunTouch Plus negative ion generator. This model offers light therapy along with the release of negative ions. Using light to complement the negative ions is a great way to boost your mental state and to help you feel refreshed during this dreaded and dreary winter months.

Price

Like with any product that you can find on the market, the prices of the negative ion generators greatly vary. Generally, these devices are quite affordable, given that they are meant to provide you with cleaner air to breathe. For example, you can purchase a negative ion generator for as little as $65. This is the case with our Editor’s Choice, the TREKOO Air Purifier. If you want to get an idea of something more on the expensive side, you’re looking to spend roughly $200 for the Dreval D-903 Air Purifier. Overall, you’ll find most negative ion generators to range between $50 and $125.

FAQ

Most of the negative ion generators use disposable filters, and they are generally not meant to be cleaned. With these disposable filters, they usually should be replaced once every six months or whenever you start to notice a significant reduction in the quality of the air you’re breathing. For instance, if you notice that the odors that your negative ion generator is recommended against are still lingering in the air, it’s most likely the time to check up on your filter to see if it needs to be replaced.

It’s best to place your negative ion generator in an area that won’t impede its ability to disperse negative ions into the air, such as spaces that can confine it or enclose it. Try to put it out into an area that is very spacious and open so that it can be as efficient as possible in a larger area. You can put it on a table, on a kitchen countertop, on your computer desk, or even on the floor. Wherever it won’t be crowded is the best place to put it in your house.

It’s best to run your negative ion generator as much as you can in the room that you spend the most time in. Some of these negative ionizers have timer modes on them that enable you to run them for a set amount of time before it switches off. It’s good to take advantage of this feature in case you don’t spend a lot of time in the room. Some other negative ionizers also have different modes that allow you to play around with the settings for different modes. For example, the settings for your sleep mode might be different than the settings you set for it to work during the day.
