OPOLAR EV01 Evaporative Humidifier Review: Affordable 2-in-1 Machine!

Last updated on April 19th, 2021

The starters

For an evaporative humidifier and air purifier at this price range, OPOLAR EV01 build quality is commendable. The entire structure is well-fitted with no sign of leakage, vibration or condensation. At only 8.4 lb in weight and 11.9 x 17.5 x 9.4 inch in size, moving the humidifier is an effortless task with both hands caring. Right at the top, you have the bezel air outlet grille and a center water inlet for mist dispersion. The top filter cover can easily be taken out for water refilling and cleaning. Right on the side, there’s a water level window and overflow hole for a convenience lookout. Moving to the bottom, there’s a hidden small water outlet cap next to the rubber seal that hardly anyone will use it.

Let’s talk about the front semi-digital control. There are 5 buttons on the black panel with indicators on each button. The center red button will turn on/ off the machine. THE top ION button will activate/ deactivate the anion function. On either side, you can either activate standard mode which has high mist output or quiet mode with low mist output. The blue indicator will lit up letting you know what mode you’re in. Lastly, there’s a bottom timer button that will cycle between 2h, 4h, 8hr preset.

Airflow, speed, and CADR

Produce about 200 ml/ H of invisible cool moisture output, OPOLAR EV01 has more than adequate airflow output in standard mode. In quiet mode, the low moist output is only meant for close-range or night time use. With a slightly smaller 0.8 gallon water tank, you can still run the air purifier humidifier all-day without refilling. No issue if you are planning to use it in a small room next to your bed, sofa, or work desk.

What’s inside count

OPOLAR EV01 relies on the standard evaporative technology with the support of an ionizer. First, the ionizer will make airborne impurities fall from the sky due to the heavier weight. Then the humidifier will be pull in the dry air through the soaked wicking filter. The ultra-thin fiber made honeycomb filter will then block out all the unwanted impurities from the air. This includes dust, mold, pollen, bacteria, and pet dander. As the air is now purified, it will take it the water and evaporate clean mist into the air. With optimum humidity, OPOLAR EV01 will gradually improve the surrounding air breathability. It will also help control allergies, moisture dry skin, and protects furniture from dry crack.

Keep it down

OPOLAR EV01 noise level is on the low side regardless of which mode you're in. With the built-in low-pitched fan, expect minor fan noise at standard mode and virtually silent in quiet mode. Perfect for a peaceful goodnight sleep. Being an evaporative humidifier, power consumption is also on the lower end at an average of just 18 watts per hour. Expect an even lower power output with ionizer off and in full-time quiet mode.

At what cost

A 2-in-1 evaporative humidifier with a digital control and ionizer for less than 80 bucks. Needless to say, OPOLAR EV01 gets a pass in our affordability book. Same goes with the filter replacement cost, at around 21 dollars annually, you'll get 2 wicking filters that should last you for an entire year. Still, OPOLAR EV01 cannot be used as a substitute for an air purifier due to the limited filtration depth. You will be better off with another separate air cleaner running alongside it.
