Rising air pollution causes 4.6million deaths worldwide annually. Adding more sorrow to this, experts say the air you breathe inside your home is 3 to 4 times more polluted than the air outside your home.

So, in this article we are going to tell you the best Air Ionizers that will help you to save you and your family form the hazardous effects of air pollution inside your home.

Air Ionizers destroy harmful allergens like dust, pet dander, pollen, spores etc. from air inside your room and help the people suffering from Asthma, allergy or other breathing issues to breathe healthy and fresh air.

But, be careful! While using Air Ionizers, a happy coincidence with them is that they are also Ozone Generators that removes bad odor from your room. Since, Ozone is a harmful gas for your respiratory system at higher levels, please remove 3P’s from your room namely People, Pets and Plants before cleaning your room with Ozone.

  • Maximum Cleaning Area of Air Ionizer: It tells you how much area your Air Ionizer can effectively clean. Thus, as the size of your room increase, the maximum cleaning area of your Air Ionizer should also increase. It is recommended to buy an Air Ionizer which has 20-40% larger cleaning area than your room size.
  • Is it 2-In-1, Air Ionizer as well as Ozone Generator? Most of the Air Ionizers are 2-in-1 as Air Ionizer can only destroy air pollutants and not deodorizes the air. For that purpose, Ozone generation feature is required as ozone removes bad odor, paint smells, spores etc. from your room. So always check if your machine is having this dual feature or not.
  • Ozone Output Rate: Ozone Output Rate tells you how many milligrams of ozone is generated per hour (mg/hr.). If you have a large size to clean then you need a high ozone output air ionizer as it will take less time to clean your room. This will save your time.

How to Choose the Best Air Ionizers?

If you are confused related to what specifications and features you need to have in your Air Ionizer, then you must go through the factors we have described below. These factors majorly decide the performance of your Air Ionizer, and having the correct combination of these features will give you the best experience with your machine.

It will also help you in investing your money in the right Air Ionizer with right features and right specifications for you.

1. Maximum Cleaning Area of Air Ionizer?

This factor tells you the maximum area size your Air Ionizer can effectively clean. So, the size of your room is an important factor while choosing Air Ionizers. A big size room will require large area Air Ionizer, on the other hand, a small size room will require a small area Air Ionizer. For optimal performance buy an Air Ionizer which has 20-40% larger cleaning area than your room size.

2. Is it 2-In-1, Air Ionizer as well as Ozone Generator?

You should always go for the Air Ionizer which has ozone generation feature in it. This feature removes the bad odors, molds, spores, paint smells etc. These things cannot be tackled by Air Ionizer alone as it only removes allergens and pollens from the air. However, nowadays all the Air Ionizers are ozone generator as well. But still, always check this feature in product information before buying your Air Ionizer.

3. Ozone Output Rate

In the above point, we told you that your machine should be an ozone generator as well. Now it becomes important for you to know, how much ozone it generates per hour. This is known as Ozone Output Rate. It tells you how many milligrams of ozone is generated per hour (mg/h).

As Ozone Output Rate increases the lesser time your machine takes to ozone clean your room. So, having a high ozone output Air Ionizer will save a lot of your time. But as this rate increases, the cost of your Air Ionizer also increases. So, choose your Ionizer wisely.

4. Timer Function

This feature lets your Air Ionizer ozone clean your room continuously for the specific period of time set by you and then stops automatically.

Since ozone is a harmful gas thus you should not be present in your room while ozone cleaning is going on. For that purpose, the TIMER FUNCTION is required for automatic stopping of your Air Ionizer.

However, if your room size is large then a less timer function machine will not be worthy as you will again have to start your machine to clean.

Most of the Air Ionizers come with maximum 120 min timer function, but if your room size is large go for the large timer function ionizers like AIRTHEREAL MA10K PRODIGI which has 720 min of timer function.

5. Service Life of Ozone Plate

Ozone plates are responsible for creating ozone gas for ozone cleaning of your room. So, they should be long-lasting as they are costly to replace. Hence, go for the Air Ionizer which gives you longer service life ozone plates.

Ozone plates have service life from 5000 hours to 20,000 hours and even more. But as this life increases cost of your Ionizer also increases. Some brands give you the option of free replacement of your ozone plate once in 5 years like DKMHA AIR IONIZERS.

You can try having such brands as this will remove your headache of replacing your ozone plates but the cost of your machine will increase.

6. Airflow Rate (CFM)

This tells you the amount of clean air (in CFM) released by your Air Ionizer.  Higher the CFM count, larger the space Air Ionizer can clean.

So, to clean air in your room faster, you should focus on buying an Air Ionizer which has high CFM. Also, as your room size increases the CFM of your machine should also increase as it will take more time to clean your room with low CFM Air Ionizer.

Along with this, the right CFM value is also important to maintain proper airflow in your room and ideal turnover of air.

7. Noise Level

Every machine produces noise or sound due to the mechanism they apply in their working.

Air Ionizers are nothing different they also produce noise. Some brands will give you high noise levels while some with better design give you low noise levels.

Your priority should always be to buy the one with low noise levels. As in need of removing air pollution, you don’t want to increase noise pollution in your home. This will also not disturb the children studying in the room.

8. Build of the Air Ionizers

Size of your Air Ionizer is also Important to consider as you need to take it to different rooms for cleaning the air. So, having a small size and less weight Air Ionizer will let you move it easily from one room to another.

Many ionizers have well-designed rubber handles that do not hurt your palms while you lift them to carry with you. So, you should try having the one which is easy to move.

The material of your Air Ionizer is also important as it ensures the longevity of your machine. Some of them are made with stainless steel while others are made with different alloys of metal. Your job should be to select one which is anti-corrosive and lasts longer.
