Understanding Indoor Air Quality
Air pollution is a common source of indoor air quality issues, and it is important to understand the sources and impact of pollutants.
Common sources of pollution
The air inside our homes can hold lots of pollution. Here are some top sources of indoor air pollution:
- Particles in the air: Small bits of dust and dirt float in our home’s air.
- Allergens: Things like pet hair and pollen are common. They can make us sneeze or itch.
- Nitrogen oxide emissions: Gas stoves and heaters give off this bad gas.
- Endotoxin presence: This is a toxin that comes from bacteria.
- Mould growth indoors: Damp spots can lead to mould, which is not good for us to breathe in.
- Secondhand tobacco smoke: If someone smokes inside, this makes the air dirty.
- Biological contaminants indoors: These could be germs or bugs too small to see, but they get into the air.
- Outdoor air pollutants: Sometimes bad air from outside can get in through windows or doors.
Importance of improving air quality
Clean air is good for us. Air that’s clean lets us breathe easily and keeps us in good health. It’s not nice when you can’t escape dirty air even inside your own home. This kind of pollution indoors can harm our bodies, make us ill, and cause breathing problems.
Better air quality at home stops this from happening. Clean air has fewer pollutants and allergens, which cause asthma and other sick-building syndrome diseases. Studies show a clear link between clean indoor air and better health for people living there.
This shows why it matters so much to look after the air in our homes well by using things like proper ventilation and correct use of heating systems.
How to Improve Indoor Air Quality
Improve indoor air quality by implementing source control, ventilation, and air cleaning methods.
Source control
Start by finding the things in your home that cause bad air. They could be dust, mould, or harmful gases like smoke from cooking. Try to stop these at their source. For instance, keep your house clean and allow fresh air to come inside often.
Also, don’t let people smoke indoors, and make sure you fix wet spots so mould cannot grow there. Keeping a lid on indoor sources of pollution is what we call ‘source control.’
Ventilation
Letting fresh air into a room can improve indoor air quality. This is called ventilation. Open windows and doors to let outside air in, or use fans to move the air around. Ventilation helps remove bad smells and reduces the number of harmful particles in the air.
It’s good for getting rid of pollen, dust, mold and toxic gases.
Air Cleaning
Clean air is a must at home. Air cleaning can help get you there:
- Air cleaners, or air purifiers, grab dust and allergens. This lets you breathe in clean air.
- HEPA filters in air cleaners really work well. They trap tiny particles like pollen and mould spores.
- Using activated carbon filters is also good. They are great for odour control.
- You can find filters that kill toxic gases, too. This keeps your indoor air quality high.
- Some air cleaners use ionizers to freshen up the air. They make dust particles stick together, so it’s easy to filter them out.
- UV light purification attacks airborne contaminants. It is used to clean the air of bacteria and viruses.
- Not all cleaning units cost a lot of electricity. Look for those with low power costs to save money.
- Always check for room coverage before buying an air cleaner. Make sure it can handle the size of your room for best results.
- Replacing your filter on time is key, too. A clogged filter will not clean the air well.
Types of Air Purifiers
There are several types of air purifiers to choose from, including HEPA filter-based purifiers, ionic purifiers, ozone generators, UV purifiers, and air scrubbers.
HEPA filter-based
HEPA filter-based air purifiers are great for indoor use. They catch small, harmful bits from the air. These may include dust, pollen and pet dander. This makes them a popular choice among people with allergies or asthma.
The filters work in a special way to clean the air around you. They trap particles in a thick mat of fibres, pulling polluted air in and pushing clean air out. An added bonus is they do not release any toxins into your home while cleaning the air! Thus, choosing a HEPA filter-based purifier means getting cleaner indoor air without adding more harm to it.
Ionic
Ionic air purifiers work in a unique way. They use electricity to trap harmful particles from the air. These purifiers send out charged ions into the room. These ions bond with dust, pollen and other bad stuff in the air.
The bonded particles become heavy and fall to the floor or stick to walls. You can clean them up by dusting or vacuuming your room regularly. Be sure you are okay doing this extra cleaning if you choose an ionic air purifier!
Ozone generators
Ozone generators are a type of air purifier that produces ozone gas to clean the air. Ozone is a molecule made up of three oxygen atoms, and it can help eliminate odours and kill bacteria and viruses in the air.
However, ozone generators should be used with caution, as high levels of ozone can be harmful to humans and pets. It is important to follow the manufacturer’s instructions carefully and avoid excessive exposure to ozone when using these devices.
Consider other types of air purifiers if you have specific needs, such as allergies or asthma, as ozone generators may not be the best option for those conditions.
UV purifiers
UV purifiers, also known as UV germicidal irradiation systems or UVC light purification, use ultraviolet (UV) light to kill germs and bacteria in the air. These purifiers work by emitting short-wavelength UV-C light that damages the DNA of microorganisms, preventing them from reproducing and spreading.
Unlike other types of air purifiers that capture particles, UV purifiers can eliminate airborne contaminants such as viruses, bacteria, and mould spores. They are particularly effective at reducing the spread of viruses like influenza and COVID-19.
However, it is important to note that UV purifiers do not remove dust or allergens from the air, so they should be used in conjunction with other filtration methods for optimal results.
Air scrubbers
Air scrubbers are another type of air purifier that can help improve indoor air quality. They work by using a process called adsorption to remove pollutants from the air. Air scrubbers have filters that capture particles and harmful gases, such as pollen, dust, mould spores, and volatile organic compounds (VOCs).
They are particularly effective at removing odors and chemicals from the air. Air scrubbers are often used in industrial settings or during construction projects to prevent airborne contaminants from spreading.
