Need an air ionizer that you can bring with you all the time? If it is a Yes, there are a few considerations that you have to make before you purchase anything.

First, consider the following questions:

Do you spend a lot of time driving and want a clean air? Does your job requires you to drive everyday? Most drivers I know often face with bad air conditions. The solution is to have an ionizer that can be used in a car.

Since they stay in their car most of the time, why not get a car ionizer? Batteries are not required as it runs on car electricity. Most car ionizer are strong enough to clean the entire car compartment so I recommend these ionizers for drivers.

Do you work in a polluted environment? If you are working in a place where air is often polluted, you ought to invest in a good portable air ionizer. Now, we should be smarter here: If it is the working place itself, ask your company to get a good air ionizer.

Of course, it's up to the company and I think that if they see more medical leave due to working place, it is wise for them, in the long run, to do invest in a good one.

Now what if your company isn't interested in getting one? Invest in a personal air ionizer or a small tabletop ionizer for yourself at your workplace.

Asthma or allergy?

A person with asthma or allergy (eg. fur, dust, etc) should always carry an air ionizer with them. There are many air ionizer that enables you to sling over your neck as you move. If you are not comfortable with a slinging device and you may want to consider an ionizer that clips to your waist.

Note that if it clips to your waist, it may not be effective because it is 'far away' from your nose. Try out the products before you decide.

In addition, I would recommend that you have a powerful air ionizer at home and one ionizer at your office desk.

Are you looking to have an air ionizer for 'just in case' purposes?

Sometime, you just want to have an air ionizer that you can bring along, without the need to carry power cables or batteries. Would it be possible to have this portable air ionizer?

Would you believe that there is this product called the USB air ionizer? Now isn't that interesting?

Obviously, the device is tiny, so try not do give high hopes on this one but this is truly a portable air ionizer that frees you from cables and batteries. People with asthma or allergy will find it useless, so this product is not recommended, but I do recommend that this can be used in conjunction with other ionizers.
