Should You Invest In An Indoor Air Purifier? Know Here

Truth to be told, the air quality in the city is not as good as before. There are lots of factors that affect the quality of the air we breathe outdoors. Pollution from transportation and industrial sectors are the biggest culprits. Meanwhile, airborne diseases and viruses seem to be more prevalent these days. Another factor that impacts the air quality is the natural allergens, such as pollen, dust, and pet danders that trigger our allergies.

We are not safe even at home. That is why many people buyindoor air purification systems for their homes and offices to improve the quality of air people inhale. But the question is: is an indoor air purifier really effective in filtering the air? How does it work?

What Is An Indoor Air Purifier?

An air purifier, air filter, or air cleaner are equipment that filters the indoor air to remove harmful particles such as impurities due to pollution, pet hair and dander, and allergens like dust, mould, mildew, and pollen.

Most houses use a portable home air purifier in Singapore, whilst offices incorporate their indoor air purification systemswith their heating, ventilation and air conditioning (HVAC) systems. Smaller workspaces also use a portable office air purifier in Singapore.

How Does An Air Purifier Work?

Indoor air purifiers use filters and fans to do the filtration process. As the fan sucks the air, the indoor air goes through multiple filters to remove the particles. The machine pumps the air back into the room after the process. The layers of filters are usually made of mesh, paper, and fibre.

A modernhome air purifier in Singapore uses High-Efficiency Particulate Air (HEPA) filtration system. The HEPA system is designed to capture microscopic particles and impurities that ordinary filters can’t collect.

Meanwhile, an absorbent indoor air purifier uses an absorbent material that attracts the impurities in the air, hence collecting and absorbing them.

On the other hand, UV purifiers kill microbes and viruses in the air. UV filters use the same process as HEPA purifiers, only with UV-C light instead of filters. The UV-C light breaks down and destroys the viruses during the filtration process.


Indoor Air Purifier: Advantages and Disadvantages

ADVANTAGE: Eliminates Unpleasant Odours

Home air purifiers are effective in neutralising and removing foul odours in enclosed spaces, such as rooms. Generally, unpleasant smells are caused by air particles and pollutants.

A portablehome air purifier in Singapore can help eliminate pet odours, the putrid smell from the kitchen or dirty items such as socks and laundry. Chemicals and gases, such as gasoline and smoke, give off a strong and irritating odour as well.

Activated carbon filters found in indoor air purification systems help collect and trap these microscopic pollutants, neutralising the odour in the room.


Unfortunately, a home air purifier in Singapore is demanding when it comes to maintenance. It is advisable to clean your indoor air purifierevery three months to keep the optimum performance of your appliance. Maintenance is crucial for this type of appliance as it accumulates dust and impurities.

Another drawback of maintaining anindoor air purifier is that few of its filters are disposable. Although there are washable and reusable filters, high-grade filters are usually disposable and cost a lot.

A portable office purifier in Singapore with dirty filters usually consumes more electricity to maintain its optimum performance.

ADVANTAGE: Reduces Asthma Attacks

Air purifiers are known to collect allergens such as pollen, dust, dust mites, moulds and mildew, and pet hair and dander. These allergens trigger skin allergies and asthma attacks.

Likewise, it also reduces the risks and chances of developing respiratory diseases caused by pollution, smoke, and toxins in the air.

With fewer allergies, respiratory diseases, and asthma attacks courtesy of the indoor air purifier, people reported having a better quality of sleep.

HEPA home air purifier in Singapore traps and collects particles and impurities smaller than 0.1 μm.

DISADVANTAGE: Ozone Emission

Unfortunately, there are indoor air purifiers that emit ozone. Ozone is a reactive and unstable gas that damages the cells, especially the cells found in the lungs. Inhaling too much ozone can cause shortness of breath and makes your lungs vulnerable to microorganisms and toxins.

An office air purifier uses an amount of ozone to help clean and purify the air, kill bacterias and viruses, and remove odours. Yet, long exposure to ozone may take a toll on health.

Someindoor air purification systems manufacturers may claim little ozone production and emission on their indoor air purifiers. Manufacturers also use different names for ozone, such as activated oxygen and energised oxygen. It is advisable to check the ozone emission of an indoor air purifier before purchasing.

ADVANTAGE: Increases Life Expectancy

Indoor air purification systems improve the quality of breathing inside the house and office by eliminating all the unpleasant smells. It also removes toxic chemicals from pollutants like asbestos and other industrial smoke. These pollutants increase the risk of developing life-threatening respiratory problems. An indoor air purifier also reduces the chance of contracting diseases caused by viruses and bacteria as air cleaners efficiently filter these microorganisms.

There are fewer allergic and asthma attacks with cleaner indoor air as well. A portable office air purifier in Singapore also filters cancer-causing agents emitted by harsh chemicals such as paint, varnishes, gas, and other substances.

Therefore, owning a home air purifier in Singapore increases the life expectancy of the occupants.

DISADVANTAGE: Can Be A Breeding Ground For Bacteria

This disadvantage is a product of a poorly maintained indoor air purifier. If air purifiers are poorly maintained or remain unclean for a long time, their filters can be a breeding ground for the bacteria they collected. Filters accumulate tons of air impurities, which include dust, mould, viruses, and bacteria. Microorganisms love to multiply in such dirty environments.

Therefore, you are reversing the positive effects of an indoor air purifieron health by neglecting maintenance. Air purifiers should be cleaned every three months.
