The quality of the air you breathe matters. It will affect your respiratory system and your overall health. Interestingly enough, studies show that there is lower indoor air quality than the air that you breathe outside.

This means that if you spend most of your time indoors, for instance in the office, you could be probably breathing in some pollutants in very high concentrations. An air purifier will definitely come in handy.

In this article, we will look at a question that you could have asked yourself several times: do I need an air purifier?


What is an air purifier?

To effectively answer this question, we will define an air purifier first. An air purifier can be simply defined as a device to help filter pollutants from the air. Sometimes, they are referred to as cleaners or filters, though some air purifiers do not use filters.

If you suffer from allergies or are asthmatic, this device will help to reduce contaminants, getting rid of the allergens and contaminants.

Commercially graded air purifiers come in different sizes, types, designs, and functionality. They are usually small stand-alone units or even larger ones. They can be affixed to HVAC units or AHU (air handler units).

In industries, air purifiers are used to remove impurities from the air before processing takes place. Click here to find out more about air purifiers.

Do I need an air purifier?

After looking at what an air purifier is, and some of the ways that it can be used, let’s go back to our question, on whether an air purifier is necessary. An air purifier is a necessary device to have if you are looking for quality indoor air, as aforementioned.

Let’s delve more into why you should consider buying this device:

It captures ?the really small particles

Air purifiers do help to get rid of allergens. However, pollen is way bigger than some particles caused by industrial pollution for instance.

These smaller particles contribute to particulate pollution, which affects more people than any other pollutant, according to the World Health Organization.

These particles penetrate the lungs and can even get into the bloodstream. Can air purifiers then capture the small particles?

Most purifiers use HEPA filters. There are several filters, sometimes even 4 filters. The more the number of filters, the more the air has to take a “torturous path” increasing the success rate at removing particles.

A recent research by Dr. Richard Saint Cyr in Beijing using a laser particle counter involved testing whether air purifiers could remove particles as small as 1 micron.

The tests were under real conditions. The results showed that the air purifiers successfully removed the smaller particles.

It can help with gas pollutants

When you buy new furniture, the smell will simply not go away. This smell is actually chemical pollution. Cleaning products, air fresheners, and paints also release VOCs (volatile organic compounds) like formaldehyde.

Formaldehyde is classified as a carcinogen and could cause nausea and headaches. It could also worsen asthma. Another common VOC is phthalates, which could result in birth defects and hormonal abnormalities.

An air purifier with activated carbon will help to get rid of these harmful gas pollutants. It will help to get rid of other pollutants resulting from domestic activities like cooking and vacuuming. Tobacco and pets are also common sources of odors in the home.

Activated carbon removes these small molecules resulting from odors and chemicals via a process known as adsorption. Activated carbon takes up air molecules, bonds to them and holds them within the purifier’s filtration system.

Different varieties=different options

As above mentioned, air purifiers come in different sizes, designs, and functionality. A whole house purifier will come in handy if you have a forced heating or cooling system. If you go for a thick purifier, it will cost you more and incur other charges like installation.

There are also portable purifiers which clean a particular area. Larger models capture most particulates as their filters have a larger surface area.Go for a filter that will best suit your needs.

No need to go for a whole house filter if all you need is to clean air in a particular area of your home. Since you also need to keep replacing the filters, at least once a year, you may want to consider this cost.

What about ionizers?

As we do our best to ensure high-quality indoor air, it is important to discuss whether ionizers can act as good air purifiers. Strong ionizers do purify the air, but with various unwanted effects. Ionizers work by removing negative ions.

These ions then stick to surfaces like the floors, walls and other surfaces. These ions result in ozone levels that are way above safe levels. Moreover, the ions can easily be dislodged back into the air, beating the whole point of removing them in the first place.

The other side of the coin

We have looked at how effective air purifiers can be in getting rid of pollutant and contaminants in indoor air. However, you may not need an air purifier if you have taken measures like better moisture management, controlling source contaminants and improved ventilation in your home or office.

If you still encounter issues like headaches, allergies, and asthma, you cannot do without a good quality, efficient and effective air purifier.An interesting point of view with regards to our question comes from scientific research.

People with allergies and asthma reported decreased symptoms when they used air purifiers. They, however, used the same amount of medication as people who are not using purifiers. This means that a purifier makes it easier for people with allergies to cope with their condition, but does not cure it.

All in all

Do I need an air purifier? Is this device part of luxury home stuff?

This question is best answered depending on your own needs. If you think that you actually need this unit, the best way forward is to first ask yourself why you really think it is necessary. The next thing you need to do is to identify the sources of contaminants and pollutants.

Is it possible to get rid of them or reduce the levels of contamination? If not, an air purifier will come in handy. After you come to this conclusion, do proper research on which device best suits your needs.
