Cosmo Prime Air Purifier Review: Breathe Easy!

Product Review

If you know me personally, you would probably be aware that both I and my husband are complete sticklers for cleanliness and hygiene. It is an area of our lifestyle where we do not compromise at all. So unsurprisingly, this trait reflects in our home. Even with busy schedules and two young children, we have always made it a priority to maintain a clean and healthy home. 

We recently did a makeover for the kids bedroom to make the small space aesthetically pleasing as well as fully functional. With the bunk bed, wardrobe, study table, dresser and storage units in place, we felt like we had tackled the main areas. Since the room already had a CCTV camera, air-conditioning unit and a wall-mounted fan, I couldn't think of anything else the room needed until I received an e-mail about a product review for an air purifier. 

The quality of air inside my home was the one thing that I had not seriously considered. It is probably because Singapore enjoys better air quality than most Asian cities. I admit that the only time the air becomes a priority for us is during the few weeks/months of "haze" that Singapore suffers from due to forest fires in neighboring countries during the months of June-September. During that period the Pollutant Standards Index (PSI) readings are frequently in the "unhealthy" range and like most people, we are weary of stepping out of the house. 

But then again, the air indoors can be polluted by mold, dust, cleaning chemicals, cooking by-products, pet dander and many other invisible products that tend to build up in our homes. It is often the case that we tend to invest a lot of time and money into our diet and make the effort to keep our bodies hydrated. But how often do we think about the quality of air that we breathe that is just as important as food and water for our survival?  

Today's air is much more polluted than it used to be. With an increase in population growth comes an increase of energy use and production which negatively impacts the air quality.  

Air purifiers can help keep the air in our immediate surroundings clean.  Dust and mold commonly collect in homes and can lead to respiratory issues such as asthma and allergies. Air purifiers remove these toxins from the home in addition to airborne bacteria and viruses to allow for improved breathing and overall health.

One of their top recommendations for air purifiers happened to be Cosmo Prime Air Purifier which uses trademarked technology and smart design to provide a long-lasting, silent and powerful air purifier.

Features of Cosmo Prime Air Purifier

Designed in Germany, Cosmo Air Purifier boasts medical grade H13 HEPA technology which means that it comes equipped with a revolutionary 3-in-1 HEPA Filter. Unlike regular HEPA filters, this ultimate filter has been engineered to filter up to 99.97% of all air pollutants (down to 0.1 microns) including smoke, dust, dander, other harmful chemical and infectious agents in addition to pollen, dust, mould, bacteria and dust mites. 

The first pre-filter intercepts large suspended particles such as hair, dust, lint and fur. The second H13 HEPA filter removes microparticles and blocks germs and allergens while the third activated carbon neutralizes odors in the air and absorbs formaldehyde. Plus, these filters have pores that are up to 20 times finer than your average HEPA filters, hence ensuring that it traps the fine pollutants that it claims to. 

It also has a Clean Air Delivery Rate (CADR) of 400m3 and a coverage area of 80m2 – making it perfect for most rooms.

I was delighted with the color of the product since it matched the color scheme of the kids room! With a sleek and modern cylindrical design and dimensions of 27 cm (w) x 30.3 cm (l) x 49.7 cm (h), the air purifier fits seamlessly into any kind of room and looks quite chic. And it is unexpectedly light weight. It even has a cute handle for easy transportation. 

I would recommend that you read the instruction manual before plugging in the machine. The HEPA filter is protected by a plastic wrapping which you would need to remove first before fitting it back into the machine. After that, you are good to go!

When you press the power button the default wind speed mode is medium. 

You will notice the indicator light change sequentially from blue - cyan - green - yellow - orange - red - purple, which will last 30s for pre-heating. After 30s, the light indicator will reflect the true air quality. Blue = good air quality, yellow = average air quality and red = poor air quality. The digital display will also show the PM2.5 numerical reading according to the air quality.

I was super stoked to see that the air quality in my home is indeed good! 

You can adjust the wind speed according to 4 settings: Auto-High-Medium-Sleep. I usually turn on the Sleep Mode because this function turns off the LED air quality lights.

Since the Cosmo Prime Air Purifier is located in the children's room, I always make sure that the Child Lock Button is enabled. This ensures that my inquisitive littles ones don't go experimenting with the settings! All you have to do is that whilst the purifier is on, press the Light/Child Lock button for 3s to activate the Child Lock Function. Do the same to unlock the function.

You can use the Anion/Filter button to start the anion generator. Anions are scarce in cities but abundant in forests, mountains, waterfalls, beaches and oceans. Anions have many benefits to the human body including enhancing immunity, alleviating allergies, promoting deep sleep and boosting mood. 

This air purifier is designed to do its job silently (as low as 20 decibels for sleep mode). You can take my word for it that it is barely more audible than a whisper!



  • Keep the machine away from water (don't place under aircon unit to prevent condensed water from dripping on it). 
  • Keep the filter clean with a soft cloth but do not wash the filter or use a vacuum cleaner to clean it. 
  • Do not use flammable, abrasive or corrosive cleaners to clean any part of the unit. 
  • You can sterilize the filter under sunlight at regular intervals. 
If you were wondering how often you need to change the filter, it is recommended for you to change the 3-in-1 HEPA filter every 12-18 months, depending on air quality and usage. The proprietary filter costs $130.

  1. I was always hesitant to use ACs/air purifiers saying natural air is what we ought to be taking in but all our manmade pollution got me thinking otherwise. This product seems quite good to own. I value reviews like yours. Not only you put in your thoughts and observations but also introduce the product to us factually. That's how a review should be.
