Yes, air purifiers with a HEPA filter trap polluting particles, including dust, from the air. While it is not a method of getting rid of dust completely, it helps remove the particles in the air you may inhale.

By eliminating factors that commonly disrupt sleep, such as allergens, odors, and respiratory irritants, air purifiers can help you have blissful, uninterrupted sleep. Consistent exposure to clean air can regulate the sleep-wake cycle, making it easier to maintain regular bedtimes and wake times.

Long-term exposure to indoor pollutants like radon, tobacco smoke, or volatile organic compounds (VOCs) can increase the risk of lung cancer and respiratory illnesses. Air purifiers can effectively remove or reduce these harmful substances, minimising the associated risks.

Absolutely! It’s advised to keep your air purifier turned on all day and night, even when you’re sleeping or not at home. Many people think that switching it off during the night or when they’re not present is a logical energy-saving measure, but it is recommended to keep it running constantly.

Air purifiers don’t contain any mechanisms that remove moisture from the air. They are designed to improve indoor air quality by passing air through filters and/or other purification mechanisms in order to remove harmful particles, gases and microorganisms.

A standard room air cleaner, operating continuously, uses approximately 100 kWh per year in electricity.

If you do not want further contaminants from an outside source entering the room while cleaning it with an air purifier, close both windows and doors for maximum effectiveness. But, if they do happen to be left open, the air purifier will clean the new pollutants that enter the room from a window or door, as well.

They cannot collect PM 2.5 particles. However, it can inhibit hazardous substances which are known to be found in PM 2.5.

The following references can be used as guidelines when comparing noise levels:

• Electric Toothbrush: 50-60 dB

• Standard vacuum cleaner: 70 dB

• Bedrooms at night-time (for adequate rest and sleep): 35-40 dB

Cleaning frequency depends on the area quality. JO air purifiers remind users for cleaning by showing smiling face instead of AQI numbers on the display.

The only consumable part in JO air purifier is the catalyst filter. Usually it can be used for 2 years if you regularly “dry” the catalyst filter under the sun every 3-6 months. But the actual usable life depends on where it is used (for example a smoker’s home or around pets) and how often it is used.

The replacement frequency depends on where it is used. Whether you have pets or cook a lot affects the usage life. Normally it varies from 6 to 24 months. But we also have customers who never change them.

The catalyst filter may be replaced if it begins to collect odor. When it starts to collect odor, you can first take out the filter and put it under the direct sunlight to dry out the moisture. The evaporation process can help to remove the odor. If drying doesn’t help to get rid of the odor, it’s time to replace the filter.

You may wipe it using the damp cloth or use vacuum cleaner to suck away the dust. After that, put the catalyst filter under the direct sunlight to evaporate the moisture.

They do not “cool the room” but rather lower a person’s temperature through the “wind-chill” effect. However, this process is very effective at improving comfort in warm conditions. How much cooler you will feel in that airflow depends on the airflow rate of the air purifier, which often isn’t that high.

ActiveE technology is an Active Electron ionization technology, that collects invisible moisture in the air and applies high voltage to it to produce trillions of nano-scale active mist ions per second, which wrap around and penetrate harmful particles of viruses and bacteria to render them inactive.

A. The ActiveE technology generate nano sized water particles of active atmospheric hydroxyls that assists in eliminating present pathogens.

B. Water particles of size 5-20nm contain large amounts of hydroxyl radicals (OH). Our technology works towards eliminating viruses by stealing hydrogen (H) atoms from viruses, to destroy the virus protein and DNA.

C. Hydroxyl radicals(OH) and Hydrogen(H) combine to form water(H2O), virus now inactive.

Hydroxyl radicals exist in nature, for example in forests.

Radicals are unstable atoms or molecules with unpaired electrons. Since they are highly reactive, they react readily with other atoms or molecules to form stable molecules or ions.

The lifespan of general air ions (negative ions) ranges from in the tens of seconds to 100 seconds. ActiveE have a lifespan of approximately 600 seconds. Enveloped in water, ActiveE have a longer lifespan, which means they can effectively reach a wider area.

Apart from regular filter changes, our portable device are 100% maintenance free. No more replacing far less efficient filters and UV lamps.

The JO Air Purifier device includes a 1-year warranty. For more info visit our support page.
