What are the Causes of Indoor Air Pollution in the United Kingdom?

Indoor Air Quality (IAQ): What Are Its Pollutants And Health Effects ?

Everyone understands that we are breathing in the polluted air while working, studying, or spending time outside with our family. Some people try to be more careful and spend their time inside of their home or office. But let me tell you that indoor air pollution is 5X more than outdoor air pollution. Moreover, if you have asthma, COPD, or any other lung disease, you will be more affected by indoor air pollution.


The National Air Quality Testing Services (NAQTS) conducted four experiments with four families living in different UK locations. These experiments showed that due to indoor activities like cooking, wood-burning, painting, VOCs from personal products, and pollution coming from outside, these British families living with ultra-fine pollutant particles 24/7. The ultra-fine particles easily absorb into the body and cause several dangerous diseases.


How can you Protect Yourself from Indoor Air Pollution?


There are many ways to clean indoor air, but now I will talk about an easy, affordable, and effective way to get rid of tiny airborne pollutant particles. If you live in England and want to protect yourself and your family from the smallest particulate matter, you need an air purifier in your home. Air purifiers are specially designed for eliminating impurities like smoke, mold, dust, and pet dander. Moreover, they can absorb the bad smell in your home or apartment and provide you fresh air to breathe in.


How Does an Air Purifier Work?


An air purifier uses multiple air filtration layers to clean the air from dust, mold, spores, smoke, bad odors, and mildew. The fan draws the polluted air from an air intake grill and passes the air into the filtration system. These filters trap the airborne pollutant particles and throw the fresh air from the air outlet grill.


There are 3 standard filters (Pre-Filter, HEPA Filter, and Activated Carbon Filter) that most air purifiers use to clean air.




The pre-filter captures large particles in the air like dust, fur, human hair, and lint. This filter also protects the primary filters and prolong their lives.


HEPA Filter


High-Efficiency Particulate Air Filter (HEPA) is a pleated mechanical filter that eliminates 99.97 % of small airborne pollutant particles (0.3 microns in size) like mold, spores, mildew, pet dander, pollen, germs, and bacteria. These particles can easily penetrate the lungs and cause several health issues.



Activated Carbon Filter


Activated carbon filter absorbs smoke, bad odors, cooking smells, cigarette smoke, pet urine smell, VOCs, and other harmful chemicals. Carbon filter cleans the air from toxic gases, harmful contaminants, and harmful volatile organic compounds when air passes from the air purifier’s filtration system. I recommend using a carbon filter with a HEPA filter to purifying the indoor air more effectively and efficiently. You need to replace the activated carbon filter every three months according to the air quality inside of your home.


Keep in mind that a carbon filter is effective in killing smoke and bad smells. If you want to remove dust in your home, you need to install a pre-filter and True HEPA filter with an activated carbon filter.




Some air purifiers use ionizers to kill germs, bacteria, viruses, and bad odors. The ionizer emits negative ions and charges the pollutant particles like dust, pollen, germs, and bacteria. The best thing about ionizers is that you don’t need to replace them. Therefore, ionizers are also cost-efficient.


Moreover, if you use a HEPA filter with an ionizer, it can effectively remove dust and large particles. When you are buying an air purifier with an ionizer, you must check it is CARB certified or not. The ionizers use a small amount of ozone that can be irritating for asthma and other allergens.


UV-Light Air Purifiers


The UV-Light air filtration system is excellent in killing germs, bacteria, toxic and harmful microscopic particles in the air. This air cleaning system also can remove fungi particles. One of the iconic features of the UV-Light air filtration system is that it is ultra-quiet. Therefore, an air purifier with a UV-Light filter is best for bedrooms.


The UV-Light filtration system is a little bit expensive than other air cleaning process. Moreover, you need to replace the filtration system once or twice a year, depending on the indoor air quality. You still need a HEPA filter and activated carbon filter for cleaning the air from dust, smoke, mold, and toxic gases.
