Air purifiers are soon becoming a household name. With atmospheric pollutants increasing inside the house as much as outside, more people are turning to this smart little appliance to enjoy a breath of pure air within. But the question is: do air purifiers work? A lot of people may have this doubt in their minds regarding the effectiveness of this technological innovation. Here’s all you need to know about air purifiers.
Do Air Purifiers Work?
An air purifier is designed in such a way that switching it on helps get rid of various pollutants that float around within the four walls of our house. These include bad odour, smoke, dust, pet dander, and the like. A lot of people are allergic to such impurities. Some may even have nasal discomfort owing to these, resulting in continual cold or runny nose.
Therefore, HEPA air purifiers come as a welcoming solution to this common but seemingly endless problem in homes. Let’s take a short peek at how they really work in providing relief.
How Does an Air Purifier Work?
A lot of people are unclear about what do air purifiers do. Here’s the answer – an air purifier is an electronic appliance that is fitted with filter(s) and a fan to suck in and circulate air. The air moving around the house passes through the filter of the air purifier. In the process, the toxic particles in the air get captured between the filters. This way, the purifier is used to remove dust from air and throwback clean air into the environment.
The air purifier filters are generally made of paper, fibreglass, or mesh. They should be regularly replaced for the better and effective functioning of the air purifier.
Benefits of Air Purifier
Air purifiers have been around for some time now, and most people who have used the technology are extremely happy with its results. Moreover, scientific research also suggests that using an air purifier can help avail a number of significant health benefits. Let’s take a look at some of them:
1. Prevent Asthma
The air pollutants described earlier in this section may look seemingly harmless to many. Most of us may not even pay attention to such things commonly found in our households as dust or pet dander, for those who have pets.
But there are some who aren’t just allergic to these things, they can even suffer ill effects in their presence. Doctors say air particles dirt, dust, carbon monoxide, household cleaners, air fresheners, cooking smoke, etc., may even trigger asthmatic attacks in certain people. Air purifiers with activated carbon filters help remove microscopic impurities from the atmosphere, thereby facilitating prevention of asthma in such people. Also, for people with pets, there are special air purifiers for pets to remove pet dander and pet odors.
2. Prevent Lung Disease
For those who smoke, simply lighting up in the balcony or terrace doesn’t solve the problem. The smoke from their puff tends to spread out everywhere in the environment, of course penetrating deep into their homes. This can become a common cause for lung disease.
Air purifiers are fitted with a HEPA filter and activated carbon which helps eliminate smoke from your living (and breathing) space. Smoke from cigarettes ranges between 4 to 0.1 microns, and air purifiers are known to remove harmful toxins from tobacco or cigarette smoke at .3 microns. This means that most of such harmful smoke can be captured into a purifier. On the contrary, HEPA type filters have a slightly lower filtering threshold as compared to true HEPA filters.
3. Reduce Carbon Dioxide Levels
We grew up learning that all living beings inhale oxygen and exhale carbon dioxide. This is a natural cycle, agreed. The problem arises when this cyclic activity gets restricted to a confined space like the four walls of our house. More so when circulation of oxygen is also reduced without the existence of plants, open windows and doors, etc. This is more common when we use air conditioners in closed rooms.
Inhaling higher levels of carbon dioxide than what is permissible for the body may result in wheezing, headache, dizziness, nausea, high blood pressure, and the like. A HEPA air purifier can help lower carbon dioxide levels in the atmosphere.
4. Prevent Malaria
Did you know that air purifiers can even help get rid of teeny-weeny bugs and insects that are otherwise hard to trap by other means? These insects are common carriers of innumerable germs and diseases.
In fact, using an air purifier is a much better method than using repellent sprays which might spread harmful toxins in the air along with killings insects. Air purifiers will eliminate mosquitoes too and prevent them from spreading harmful diseases like Malaria.
5. Reduce Contamination in Healthcare Centers
Hospitals, clinics, and other healthcare agencies are easy targets for the spread of infections, bacteria, viruses, and other harmful toxins because people coming to these places are in close contact with all kinds of airborne infections. An air purifier placed at the doctor’s clinic can help remove toxic air particles before they can infect other people coming in.
6. Elevate Mood Levels
Air purifiers have been proven to help improve moods in people by making them feel less agitated and happier than ever. Some air purifiers come with ionizers that help generate negative ions. These ions are highly effective in causing positive moods, reducing depression symptoms, and even Seasonal Affective Disorder (SAD) resulting from change in weather in certain people.
7. Improve Sleep
Air purifiers have also seen to be great at improving sleep quality in people. Contaminated air can make you feel uncomfortable and disrupt healthy sleep schedules. Not to forget, it causes bad odour which is never pleasant to inhale.
Air purifiers work best in bedrooms where they help purify the air and even produce a calming sound for peaceful sleep. The sound produced by an air purifier has been compared to that of ocean waves or gentle breeze, which most people find extremely relaxing to fall asleep.
Now that you have read whether Air purifiers actually work, you might be confused about which one to buy. After 30 days of testing different Air purifier in the market, we have 60% of Air purifiers to be ineffective and only 5% Air purifiers to actually deliver that they advertise. To know which Air purifiers come under this 5%, you can read our review article here.
Whether air purifiers work or not is a subjective issue. For some, it does and provides these amazing health benefits, while some look at it as undue marketing hype. While it is partially true, as you may find inefficient air purifiers like ionizers and ozone generators that are being marketed as be-all end-all air cleaners. But, the market also has really effective HEPA based air purifiers that can be completely relied on.
