The best dehumidifier in terms of health, functionality and value-for-money

Love the versatility!

I purchased this humidifier to use in our bathroom to draw out moisture and black mold is a problem. Will occasionally use the unit in our bedroom, too. I plug it in after we are finished our showers and it works great. Barely any noise and since it’s in the bathroom, it doesn’t matter.

We just got this today and I am super excited. We had a leak in our roof , and we are trying to remove the left over moisture.

Very efficient!

I bought two of these. My apartment is very humid all year. Within the first few hours, it was pulling water out of the air. I am so impressed!.

Very Convenient to use

This dehumidifier was really simple to use, just plug it in and let it do it’s thing. We bought it for a small bathroom to take out the extra moisture. We have larger units in the bigger bathrooms that suck a tankful of moisture out over night. It’s amazing how much moisture you don’t realize is in the air.

It change my life

I bought this for my bedroom to help with the humidity and heat. Though i have central air, the bedroom doesn’t get much airflow, after using this dehumidifier for a couple weeks, I can definitely tell the difference.

Small yet powerful

I am very satisfied with the unit and would recommend it to anyone looking for a small/ portable dehumidifier that doesn’t take up a lot of space or produce a lot of noise.

Why is excessive moisture dangerous?

COSMO Prime® Dehumidifier helps to relief allergy triggers and prevention against mould and mildew growth and protects your home from moisture damage and safeguards your valuables from humidity.

How are moulds formed?

Ever-Present Mould Spores

Tiny mold particles are always present in the air in the form of tiny microscopic cells known as spores.

Moisture & Warm Temperature

Warm temperature and high humidity provides as an excellent condition for mold to grow.

Mould Growth on Surface

Spores carried by wind attach themselves onto walls, furniture and surfaces. Under humid conditions, it takes about 24 to 48 hours to grow into mold.

High Moisture

Mold grows at an astounding rate, especially on wet surfaces.

Mould Thrive & Multiply

If left unchecked, mold can destroy the beauty of your home and pose potential health hazards.

Controlling excessive moisture in your home

Excessive moisture in the air, especially at a relative humidity of 50% or higher, speeds up mould & mildew growth.

Which produces musty smells and unpleasant odour. Besides making it uncomfortable to breathe, high humidity can cause damages to your indoor environment.

Cracking & Flaky Paint

Warped Wood

Mould & Mildew

Prevent mould growth so you don't have to worry about the cleanliness of your house which means you'll have the best house in the neighbourhood.

Discolouration on walls

Wet clothing indoors can also produce excessive moisture, causing short and long-term health problems such as pneumonia and coughing.

Black mould growth in tiles.

Over 60% of your electricity in your air conditioning is directed to reducing humidity before cooling the air. Having healthy levels of humidity reduces your air conditioning from using excess electricity.

Protect Your Health

When there’s too much or too little moisture in the air, it can impact your health in more ways than you think



As counterintuitive as it may seem, too much moisture in the air can actually interfere with your body’s natural cooling mechanisms and leave you dehydrated.

Inflamed Dermatitis & Eczema


Eczema and other forms of dermatitis are often exacerbated by changes in temperature and humidity. When sweat remains on your skin in high-humidity conditions, it can lead to heat rash.

Respiratory Problems


Breathing in humid air activates nerves in your lungs that narrow and tighten your airways. The air stagnant is enough to trap pollutants and allergens like pollen, dust, mold, dust mites, and smoke.

How does COSMO Prime® Dehumidifier work?

Apart from removing excess moisture in the air, it also releases healthy negative ions in your home
