12 best air purifiers in Singapore for clean indoor air

If there’s anything COVID-19 has taught us, it would be that our health is of utmost priority under any circumstance.

Perhaps you’ve taken time to strengthen yourselves with vitamins and antioxidants — those definitely do help to boost our immune system. Yet, there’s one thing many of us overlook: the air around us.

Dr Benjamin Loh, Resident Doctor of DTAP Clinic Group elaborates: “In modern indoor spaces, allergens, viruses, bacteria and harmful gases may cause respiratory infections. In other cases, these can also result in various allergic symptoms such as sneezing, watery eyes, nasal congestion and runny nose. Atopic diseases, often associated with common allergens, can also have a negative impact on (one’s) quality of life.”

Enough said. Read on for some of the most efficient (not to mention incredibly stylish) air purifiers for healthy, clean, pollutant-free air right in the comfort of your home.

The Ultimate Buying Guide for Best Air Purifiers in Singapore

Did you know? The air pollution within your homes can be five times worse than the outside environment since most of our time is spent indoors, especially since last year because of the ongoing COVID-19 pandemic.

Thus, air purifiers have become the need of the hour for good air quality, especially inside our homes that are now doubling as the office as well for many. It is a necessity to deal with indoor pollutants and allergens that the naked eye can’t detect.

Thinking of choosing an air purifier in Singapore?  Well, there are plenty of air purifiers to select from. However, most manufacturers provide just a hazy description of how their devices operate or make health claims that may not be entirely correct.

So, how will you know which one is the best for you? We’ve put together a guide to help you go through the  best options and choose the finest, most energy efficient air purifier for your home’s size and budget.


Why buy an air purifier or air cleaner?

According to the World Health Organization, 4.3 million people die prematurely each year as a result of household air pollution from various sources and insufficient ventilation. Poor air quality is responsible for 50% of fatalities among children under the age of five.

As discussed above, the air you breathe indoors can be much more harmful than outside. Additionally, household products like deodorants, inkjet printers, and cleaning agents also contribute to indoor pollution.

Also, if a family member is suffering from asthma or allergies, it is essential to maintain the high quality of air in your home. Many purifiers absorb unpleasant odours from varnishing and paints as well.

They control the air quality by absorbing pollen dust, air pollutants, allergens and toxins. If you have a pet at home, indeed, those pet hair and dander will also be absorbed by the air purifiers.


How does an air cleaner work?

Even though air purifiers seem like a recent innovation, the technology has been available for several years. Once used as protective masks for firefighters, the technology evolved into today’s highly sophisticated air purifiers.

The working behind air purifiers’ filtration system is simple – they filter particulate matter found in air through fine sieves. As the circulating air passes through the purifier, it goes through finer sieves trapping particles as small as 0.3 microns.

Some of the other technologies used alone or in tandem with such a filtration system are electret filters, negative ion generators, electrostatic precipitating cleaners among others.


What is the HEPA filter in an air purifier?

High-Efficiency Particulate Air (HEPA) filter is the benchmark technology when it comes to air purifiers. HEPA filters are highly efficient and are capable of removing more than 99.97% of 0.3-micron particles.

PM10 refers to particulate matter that has a particle size between 2.5 to 10 microns in diameter. These particles may get trapped in your nose and throat but not beyond. At the same time, particles of PM2.5 are 2.5 microns in diameter or less in size are are so tiny that they can enter the lungs and cause several lung infections and breathing problems. HEPA filters are the ones to filter out such particles.

Air purifiers in Singapore are mostly HEPA air purifiers, as suitable for the climate.

Other effective filters in air purifiers

Besides HEPA filters that happen to be the best among all, filters like activated carbon filters and UV filters are important aspects to look for in an air purifier.

Like HEPA filters, UV filters are mainly used in kitchens, hospitals and labs to prevent the spread of air-borne diseases. They work by the usage of short-wave ultraviolet light which inactivates harmful pathogens, hence purifying air. The Carbon filters are one of the best too and are used in tandem with other filters for maximum benefits.

What is CADR Rating?

CADR or Clean Air Delivery Rate is a numerical value given to air purifiers that denote the capacity of an air purifier of cleaning a particular size of room in a set time. It is applicable both for parameters like particle removal efficiency and amount of airflow.

America’s Association of Home Appliance Manufacturers (AHAM) established the Clean Air Delivery Rate (CADR) to assist customers in understanding how efficient an air purifier is in filtering different pollutants in particular room sizes. The higher the CADR rating is for an air purifier, the higher is its efficiency.

Hence, ensure to look for a high CADR rating before purchasing any air purifier. Most of the air purifiers in Singapore have a high CADR rating

Where should you place your air purifier?

It is best to place the air purifier in a room where you spend the most amount of time. Portable air purifiers are only meant to filter the air in one area, so you might have to purchase extra units to clean the air in other rooms.

Some air purifiers can distribute air unidirectionally or in an upward direction. For example, the Dyson Pure Cool Link can oscillate, thus ejecting a steady stream of clean air across the room.

This is beneficial for the hot, humid, and the polluted stale air present in the Singaporean climate.

What is ACH?

The number of times an air purifier can filter the whole volume of air in the treated space each hour is referred to as ACH. The ACH (or commonly known as the air change per hour rate) of an air purifier denotes the exact number of times that the filter purifies the entire room in an hour.

If you are suffering from allergies or asthma and are searching for an air purifier to assist in controlling your symptoms, the air change per hour (ACH) rate should be taken into account. Allergy and asthma patients should use air purifiers to clean the air in a room at least four times each hour.

So, if an air purifier claims to have a 5 ACH (air change rate per hour) rating, that implies it cleans the air every twelve minutes. If anyone in your family suffers from asthma, choose an air purifier with an ACH rating of 5 to 6.

An air purifier cleans the air completely and filters out as many tiny symptom-triggering allergies as possible at a rate of four air changes per hour to keep you breathing easily.

What is the right weight and size of air purifier?

Bulky air purifiers can be difficult to transfer across different rooms. On the other hand, the coverage is compromised in the case of lightweight air purifiers.

Specific models of air filters have the functionality of both a fan and an air purifier. This gives you an added advantage of both the machines and removes the floor space taken up by two machines.

Consider the area of the space you wish to cleanse when choosing the correct size of an air purifier for your requirement.

The following guide will walk you through the sizes of air purifiers that you actually need for your home:

Small: These air purifiers are small enough to fit in a personal area or a room up to 299 square feet.

Medium: For rooms ranging from 300 to 699 square feet, look for a medium air purifier.

Large: These air purifiers are best for rooms with a size of 700 to 1,900 square feet.

Whole house : Whole-house air purifiers are becoming increasingly popular as a way to ensure clean air in all of your rooms.

As you heat, chill or ventilate your house, these devices connect to your current HVAC system to purify the air within.

Energy efficiency of air purifiers

Because air purifiers work best when they’re running practically continuously, you’ll also want to consider power expenses. However, the amount of electricity they use varies depending on the fan speed.

The projected energy consumption of your air purifier is generally listed in the product specifications. Some gadgets draw as little as 1.5 watts, and at the same time, there are devices that draw more than 200 watts. You might not notice the former’s influence on your power bill, but the latter might mount up.

Small air purifiers consume less energy than bigger ones but clean a smaller area. Air purifiers rated for big rooms and with greater fan speeds, on the other hand, use more energy. When their sensors no longer detect airborne contaminants, some air purifiers feature “eco” settings that turn them off and put them on standby.


Cost and maintenance of the best air purifier

If you see a cheap price tag, we would advise you to stay alert. This is because there may be some hidden costs in replacement filters, costing you around  $300 every six months.

So in no time, within a two months period, you will observe that you are paying the exact maintenance cost for the affordable machine. However, these are not the cases with the air purifiers that cost high initially.

Filter replacement prices vary per machine: some have high-quality filters that endure for years, while others have low-cost filters that must be replaced frequently.

Furthermore, while some of the pre filters may be washed, the HEPA filters are disposable and must be replaced completely.

If you’re on a budget, the upfront cost of your air purifier is important, but don’t think you’ll be done paying for it once it’s installed in your house. You’ll have to keep replacing the filters regularly.

Calculate the cost of maintaining an air purifier before you buy one, and compare it to the cost of any other air-purification equipment you might be considering. Also, check if replacing the air filter is a three-minute process or a 5-hour affair without the involvement of screwing and unhinging of different parts.


Customer service and warranty

When choosing an air purifier, it is also important to consider filter replacement and customer service. In many machines, air purifier filters require to be replaced on a regular basis.

Which is why they should be easily accessible. When you purchase air purifiers in Singapore, make sure the brand has a well-developed customer service network. This indicates that you should look into the company’s after-sale service.

A change in air preferences will be needed after every 12 to 18 months. That is also a reason why a huge investment at the initial phase will ensure you an extended warranty on the product and save you from unnecessary manufacturing issues.


How to choose the best air purifier depending on an individual’s preference

The requirement of air filters varies from person to person. Below listed are a few essential points to keep in mind.

  • People with lower immunity levels and prone to dust allergies, air pollutants, pollen dust, or allergens should get air purifiers equipped with a HEPA filter or activated carbon filter.
  • If you live in a construction zone, your air purifier must have a strong pre-filter that should be periodically replaced.
  • If you stay in an industrial zone, activated charcoal filters can remove all the foul odour and pungent chemical smell from the environment. Thus, you won’t have to deal with the ugly-smelling typical industrial smelling air.
  • If you have pets at home, a strong pre-filter in an air purifier will help absorb your pet’s hair and won’t cause any breathing issues.


Extra features to keep an eye on

Consider the fact whether you want any extra features or not once you’ve decided on the kind and size of air purifier.

  • Remote controls, easy mobility, filter change indicators, and multiple fan speeds.
  • Air quality indicators that provide real-time information on the quality of the air you breathe. Other features include caster wheels and handles for easy transport.
  • Air purifiers labeled with Energy Star-rated by the EPA will help you save money and energy. Wi-Fi air purifiers that you can operate with your phone are also available.
  • Consider the amount of noise emissions. All air purifiers or air filters have fans, which produce noise. So, if you don’t want your sleep disrupted by buzzing fans, look for the ones with low noise level.




Q1. Do doctors recommend air purifiers?

A 2011 study states that HEPA purifiers did have clinical benefits, but mainly in single room settings.

Q2: Are air purifiers good for babies?

Most of the air purifiers nowadays come with sleep mode which lets users control the noise level of the device. This will ensure not to disturb your baby’s sleep. If your baby has asthma, allergies, or sensitivity to fine particles, a good air purifier will help in managing that.


Q3: Which brand is suitable for air purifiers?

The best brands dealing with air purifiers include Dyson, Blueair Blue, Coway, Honeywell, Austin Air, pureZone, Levoit and Philips.


Q4: Do home air purifiers really work?

The air filter draws in the polluted air filled with particulate matter. After undergoing all the required processes of four stage filtration, the air purifier removes the particles along with bacteria and viruses from the air. The filtered air is then circulated back into the room.

Q5: Is an air purifier needed in Singapore?

Yes, keeping the environmental conditions and air quality of Singapore in mind, an air purifier isn’t just needed in times of seasonal haze, but it is important in helping with managing respiratory issues in the long ru.

Final thoughts

Air purifiers have become an absolute need of the hour considering the rising levels of indoor air pollution. Clean air is a basic necessity required for good health and well being. Install an air purifier today and ensure healthy air in your space at all times.
