Air Purifier | Indoor Air Pollutants Considerations | Best Products
An air purifier greatly
improves the indoor air quality by removing contaminants from air. Air purifiers
differ in filter layers, functionalities and sizes. Certain filters are capable
to filter particular contaminants. Different sources produce different
pollutants and consider the sources and their impacts choose your air purifier.
Considerations
for before purchasing an Air Purifier:
Different air purifying
technologies are created for different pollutant removal and have different
removal efficiencies. The pollutants and irritants most commonly found indoor
and impact our health greatly, include;
o
Particulate
Matter (2.5 and 10):
Cooking, burning of candles,
use of fireplaces, use of unvented space heaters or kerosene heaters, cigarette
smoking are some of the sources of particulate matter emissions. Particulate
matter are small particles and can significantly affect respiratory system and
are eye irritants. PM2.5 and PM10 are type of particulate
matter based on their sizes. PM10 are larger particles as compare to
PM2.5; these particles are stopped by nose and rarely get into your
lungs but cause eye and nose irritation whereas PM2.5 have
considerable impact on health as they get into the lungs and cause respiratory
issues.
o
Volatile
Organic Compounds (VOCs):
Sources of VOCs include paints,
solvents, adhesives; varnishes, carpets, upholstered furniture or items made
from composite wood tend to off-gas more VOCs when they are new. VOCs easily
get in air and dissolve in water as well. They cause significant health impacts
like when inhaled asthma, irritations, cancer and liver and kidney damages, and
combine with other air components to create more harmful pollutants.
o
Formaldehyde:
Formaldehyde get to the
indoors through wallpaper, cardboard, paper and paper products, varnishes and
wood items. Formaldehyde causes eyes, nose and skin irritation, and respiratory
diseases.
o
Biological
pollutants:
Bacteria, viruses, animal
dander and cat saliva, mites, pollens etc. are some of the biological
pollutants. Biological pollutants easily enter our houses in one way or
another. Bacteria and viruses have strength to drastically impact your body
organs and result in many diseases. Animal dander and hair, no doubt are great
irritants.
o
Odor:
Odor from animals and from
different activities like paints, can be really irritating and may cause
headache for sensitive people.
