Indoor air quality is a silent yet vital player in our daily lives, quietly influencing our health and well-being. From our homes to workspaces, the quality of the air we breathe matters more than we might realize.

Did you know that air quality actually has a direct impact on your health? For example, if you breathe in polluted air particles, the pollutants can get into your lungs and bloodstream. Whether it's battling cooking residue, fumes from fresh paints, or the lingering scent of varnishes, these pollutants can lead to long-term health issues, especially for those with respiratory conditions or allergies. Hence, it’s always important to maintain good air quality around your home.

Rise in Popularity of Air Purifiers in Malaysia

In recent times, air purifiers have been enjoying a steady climb in popularity across Malaysia, becoming the new go-to gadget for health-conscious folks. With the recurring haze that has becoming an annual health hazard as well as the post-covid threat to health, these sleek machines have found their way into Malaysian homes and offices. This increasing adoption of air purifiers reflects is not just a response to ever-present environmental challenges, but Malaysians generally are showing a growing interest in breathing cleaner air indoors.

So you've decided to get one air purifier, but there are just so many options in the market! Do you know which to choose? Let's go through the finer points together before deciding on one.


Understanding Air Purifiers

What is an air purifier?

An air purifier is a device designed to improve indoor air quality by removing contaminants and particles from the air. It works by pulling in air and passing it through a series of filters that trap various airborne pollutants, such as dust, pollen, pet dander, mold spores, and even some bacteria or viruses.

How do air purifiers work?

Air purifiers operate using different technologies, but most work on the principle of filtration. They typically consist of a fan that draws in air, which then passes through a series of filters. The primary filter, often a HEPA (High-Efficiency Particulate Air) filter, captures and traps small particles like dust, allergens, and other contaminants. Some air purifiers also utilize additional filtration systems, such as activated carbon filters that absorb odors and chemicals, as well as UV-C light technology to neutralize airborne pathogens. Clean air is then released back!

Common misconceptions about air purifiers

Despite their effectiveness, air purifiers are subject to several misconceptions. One prevalent myth is that air purifiers alone can entirely eliminate indoor air pollutants 100%. While they significantly reduce airborne particles, they cannot address all sources of indoor pollution, including mould which grows due to humid environments. HEPA filters can filter pollutants up to 0.3 microns, which is very small, but pollutants that are smaller than this can possibly escape the filter too.

Hence, if an air purifier advertises itself eliminating 100% pollutants, removing mould, and promising various health benefits - take note. The said air purifier is overpromising benefits which can never be provided in the first place, no matter how good the air purifier is.


Types of Air Purifiers and Filters

Types of Air Purifiers

Air purifiers come in diverse types, each with its own specialized approach to cleaning indoor air. HEPA filters are adept at capturing minute particles like dust and pollen, while UV-C purifiers employ ultraviolet light to combat germs and viruses. Ionic purifiers use ions to prompt particle settling, and ozone generators emit ozone to eliminate odors and germs, though their impact is debated. Adsorbent purifiers, armed with activated carbon filters, target odors and chemicals.

Different Filters in Air Purifiers and their Functions

Air purifier filters aren't just filters; they each play a crucial role. Pre-filters act as the first line of defense, capturing larger particles to extend the lifespan of subsequent filters. Fine dust filters tackle smaller particles, and activated carbon filters neutralize odors and harmful gases. Among these, HEPA filters shine by capturing ultra-fine particles, significantly enhancing indoor air quality.

How to Choose the Right Air Purifier for your Home

Factors to Consider When Buying an Air Purifier

Selecting an air purifier involves considering various factors. The type of purifier should align with specific air quality needs. Room size determines the purifier's effectiveness, while noise levels impact comfort during use. Prioritizing energy-efficient models and seeking Clean Air Delivery Rate (CADR) ratings ensures optimal performance and energy savings. So take note of the CADR rating of the air purifier you want to buy.

Room Size and Air Purifier Coverage

The higher the CADR, the larger the area the air purifier can help to purify air. A general rule to consider is the “2/3 rule” – the CADR rating needs to be at least 2/3 the square footage of the space. Refer to the table below:

Room Area (sq ft) 100 200 300 400 500 600 700 800 900
Minimum CADR 65 130 195 260 325 390 450 515 580

Noise Level of Air Purifiers

Think about the noise level when picking your air purifier; after all, peace and quiet matter, especially during downtime or snooze time.

Energy Consumption of Air Purifiers

Saving the world is great, but saving energy is cool too. Look for those energy-efficient models and the Suruhanjaya Tenaga badge with the four to five-star rating for the said appliance—it's like giving the planet a high-five.

Additional Features in Air Purifiers

Some purifiers come with bonus features for added convenience, like filter change reminders, remote controls for effortless adjustments, auto modes that adapt to the air, and even smart connectivity for that futuristic touch.
