BUYING GUIDE: The right ways to pick a Negative Ion Generator

An ion generator comes in any shape or form, but the best one has some commendable features. Though not all, there are a few features that you must look for while buying an ion generator, such as coverage, efficiency, design, ease of operation, portability, noise level, warranty, and price. Combined with all these features is what makes an ion generator worth buying.

If you don’t know what we are talking about, then you must be a beginner here who has never bought such an appliance. But the best part is you are in the right place to know about a negative ion generator more explanatorily. 

Coverage: different manufacturers come with different coverage areas for their ion generators. Now, what coverage you want in your purchase, depends on the size of your house, room, or the place you are buying the generator for in general.

But remember, the coverage area should be at least near to what you want if not exact. Because the one with high coverage will have high speed, which generally will disperse concentrated ozone in the compact spaces. Whereas, the low coverage area will not properly ionize or purify a large space.

Efficiency: The efficiency of an air ionizer is determined by how much negative ion it disperses every second. The efficient your ionizer will be, the better and faster it can work. Therefore, you should have a high expectation from your air ionizer irrespective of its area coverage and other features.

The reason why high efficiency is good is that most negative ions get dropped on the floor, then they get cleaned or vacuumed. Eventually, they are of no use once they fall on the ground. So the more an ionizer will disperse ions, the more will flow into the air despite some of the falls on the ground. 

Design: The modern air ionizers are designed keeping in mind the taste of new generation users. They are not those bulky and huge ionizers anymore, rather slim ones with more updated features.

To choose the design of the generator, along with its colors and variations, the choice is completely yours. But buy a design that will suit your house’s interior or match with other appliances of your house. In this way, you can hold the congruence of your house.

Easy operation: Ease of operation depends from person to person. Some people find it easy to operate them with knobs, while others with push buttons. Most importantly, every generation has different easiness.

There are still some manufacturers who put knob operation into their ionizers. This might be preferred by the older generations to handle. Whereas, mostly modern ionizers contain smart push buttons for fast and easy operation.

However, make sure the ionizer’s buttons are limited and have specific ones so that it is easy for you to understand everything. Too many buttons and adjustment modes make the operation of the ionizer difficult.

Portability: It is important for an ion generator to be lightweight enough and portable to be carried along. No, we are telling you to carry it everywhere you go. But at least from room to room in your house, you can change its placement. A compact ionizer will be great to put in small spaces.

Noise level:  you won’t want to compromise your peace with those ear-bursting noises while operating, right? Then opt for an air ionizer that has a quiet and sleep-proof operating system. Whereas, there are others that provide sleep mode or night mode in which they make no noise while they are turned in these modes.

Warranty: Normally, you will think that the best ion generators will come with a low warranty because the manufacturers trust their products’ quality. But in this case, we believe the air ionizer should have a high warranty period. Because it happens that sometimes these appliances face some issues relating to the mechanism or operation.

No matter how expensive or from a well-known brand you buy ionizer, these are still a machine. And, has high chances of showing disruption, even if it is for your negligence.

Price: If you truly believe in investing in a good quality negative ion generator that will last you for years, then be prepared to spend a little extra on them. In the case of these ionizers, quality, durability, and functionality are dependable on price.

If you wish to enjoy the benefits, and features of your ionizer for the longest time possible, then don’t look at its price. However, quality is not only dependent on the mind-blowing specifications but also on its durability. Normally, cheaper ionizers will be made with cheaper raw materials.

Ease of maintenance:  if you owe a busy hectic life, then buy an air ionizer that takes the least maintenance attention. It will prove cost-free for you in the long run. Moreover, you won’t have to service the ionizer from time to time to keep it going.

Also, look for non-replaceable filters in your ionizer. Because it may cost you a lot in the life of your ionizer to replace filters every time.

Ozone emission: even though every negative ion generator emits ozone. But the goal is to find the one with the least emission. Ozone at the ground level is toxic for every living being, also to the environment. So, you have to research well and find the most appropriate low ozone emitting ionizer for yourself.

What does a negative ion generator do?

A negative ion generator produces small tasteless and odorless air molecules or negative ions. These negative ions are naturally found in sea beaches, forestry, waterfall, and in any other soothing place on earth. Since people can’t visit these places every day out of their hectic life, they have to buy these naturally formed particles’ generators that unnaturally produce the ions.

An ion generator uses electricity to charge and produce these ions in the air. These are then inhaled by humans to achieve a calm and refreshed life. Negative ions have innumerable benefits for humans which we will know below. Along with negative ions, these man-made ion generators also produce ozone.

Now ozone on the ground is undoubtedly harmful. It triggers respiratory issues like coughing, cold, etc. in the long run. One must have restrictions in using these generators as this artificial ion generation process is not safe for too long.

Why use a negative ionizer?

Exposing your body to negative ions is crucial. Ionizing helps to heal depression, relieve stress, and lift your mood. In the daily dose of stress and negativity, people tend to have less mental peace. Moreover, they cannot go vacationing on a beach or to Wyoming whenever they want.

Hence, they need to invest in a good quality negative ionizer. When the ionized air is inhaled, it runs through the bloodstream and triggers the euphoric hormone inside your body. This in return, helps out with all the mentioned benefits. Therefore, if you want to live a peaceful life out of all the tension there, then you should also buy a negative ionizer.

You will have an improved sleep, a happy and enthusiastic mind, and a motivated individual in you.
