Coway Air Purifier Review — Is It The Best Air Purifier For A Bedroom?

Coway Air Purifier Review
Coway may be your top pick if you’re having trouble choosing a suitable air purifier for your bedroom. In a short article published by the Korean home company, the Coway Airmega 150 and Coway Airmega AP-1512HHS are highly recommended for their silent and auto features so you can have a restful sleep.
But you shouldn’t halt your research here just yet. In case you didn’t know, plenty of brands have caught up and offered air purifiers with the same features. That’s why we’ve put up a review-cum-comparison guide with the Cosmo Prime® Air Purifier — Singapore’s top ranking air cleaner. In this guide, we explain the differences between both air purifiers and re-examine which is the best air purifier for a bedroom.
1. Features 3-in-1 HEPA filtration — scientifically proven to filter pollutants

Both Cosmo and Coway features an extensive 3-Stage HEPA Filtration to combat fine pollutants indoors. It is important to note that while both brands name their filters differently, all 3 air purifiers have the SAME filtering effects.
3-Stage HEPA Filtration
Activated carbon
The Coway Airmega 150 contains a deodorisation filter which works essentially the same as Coway Airmega AP-1512HHS’s improved honeycomb activated carbon filter. Both are layers of activated carbon to remove harmful gas and odour such as cigarette smoke and the lingering smell of grease from cooking.
Like Coway’s 2 air purifiers, Cosmo’s activated carbon neutralises odours in the air and absorbs formaldehyde — a colourless, pungent gas from household products and building materials. This is crucial as long-term exposure may cause skin irritation and respiratory illnesses.
HEPA filter
Like any effective air purifiers, all 3 air purifiers are equipped with HEPA filters which remove 99.97% pollutants of up to 0.3 microns. The filter is made of fine glass threads to trap pesky pollutants such as pollen, dust mites, and common allergens.
You can read why HEPA filters are essential to every air purifier here.
2. Coverage & lifespan of HEPA filters
Aside from using HEPA filters, the cost of filter replacement and coverage are equally important factors to take into account.
Filter replacement
In terms of longevity and affordability, the Cosmo Prime® Air Purifier is a clear winner at just $399.
Coway may be more affordable at just a glance but the Korean air purifier brand does not sell HEPA filter replacements. Both the Coway Airmega 150 and Coway Airmega AP-1512HHS’ replacement policies only extend to pre-filters, top covers, and side panels.
Since air purifiers are only as effective as a functioning HEPA filter, shoppers will have to replace the entire Coway air purifier after merely a year.
On the other hand, Cosmo lasts the longest at 1-1.5 years and offers HEPA filter replacement at a low of $70 only. That means you will only need to spend another $70 for a replacement filter instead of buying a brand new air purifier.
Despite paying for $399 — a heftier price tag than Coway at the start, Cosmo offers a more sustainable solution to shoppers in the long run.
Coverage
Cosmo outwins Coway for covering twice as much room capacity — no questions asked. At 80m², that’s equivalent to a typical 4-room flat in Singapore!
3. Low noise level — suitable for light sleepers
Thanks to advanced technologies, both air purifier brands are neck to neck with each other in terms of noise levels. In non-science-y terms, 20dB is the typical volume of a whisper.
And if you wake up easily or have frequent insomnia, Cosmo’s in-built blue light may be the helpline you need to get beauty sleep. Bid goodbye to counting sheep or binge-watching Netflix. Instead, switch the blue light on about an hour before you hit the sheets for a good night’s sleep.
4. Automatic fan speed with smartphone control
Although the Coway Airmega 150 lacks smartphone access, the self-functioning air purifier senses and adjusts its fan speed according to the type of air quality indoors. You will also be kept in the loop with different signs from the LED lights — blue for good while red stands for bad air quality.
Give it an instant upgrade and you’ll get Coway Airmega AP-1512HHS. The air purifier comes with added functions such as its exclusive voice control. Young homeowners will love syncing their air purifier to Google Home or Amazon Alexa for the ultimate smart home package.
The Coway air purifier also earns extra brownie points for its eco-friendly feature. Relying on its sensitive sensors, it only turns on the fan when the air quality worsens.
While Cosmo may not match up to Coway Airmega AP-1512HHS in terms of AI technology, it certainly makes up with family-friendly features such as the child lock. This convenient feature locks all features in place so that your walking toddler can fiddle with it without any damage. To lock and unlock, you will only need to deactivate the child lock via the ‘Smart Life’ app.
5. Coway does NOT ship directly to Singapore
Probably a deal-breaker that turns potential Coway shoppers away is its shipping restrictions. Currently, Coway does not ship directly to Singapore. You can, however, get it via third-party platforms such as Lazada, Qoo10, and Amazon.
Even if you did, note that you will most likely not be insured under their warranty policy. According to Coway, all shoppers are eligible for their 30-day money-back and are covered with a 5-year limited warranty applicable to the USA, Canada, and Mexico only.
Cosmo sports similar risk-free factors such as a 20-day free trial and a 5-year warranty as well. Most importantly, all shoppers located in Singapore can also enjoy free, islandwide delivery. This includes the purchase of either the Cosmo Prime® Air Purifier or the HEPA filter replacement.
Get Cosmo Prime® Air Purifier — risk-free and fuss-free
Depending on your preference, technology-savvy shoppers may find Coway’s air purifiers the perfect fit, whereas households with small children might find Cosmo a godsend.
But when it comes to risk-free guarantees and lifespan, the Cosmo Prime® Air Purifier is an obvious choice to secure clean air in the long run. Not only can you cut down on cost with a filter replacement, Cosmo also offers free, same-day delivery wherever you are in Singapore.
