🌬 CADR 243 M³/H – EFFICIENT AIR PURIFICATION

One of the most important parameters of the purifier is CADR, which is an indicator of the efficiency of delivering purified air.

Dreo 337S achieves the declared capacity of 243 m³/h.

This means that the device can effectively filter a significant amount of air in an hour, helping to reduce the concentration of floating pollutants.

The manufacturer also used a design that allows to draw air from all directions.

The improved rotor and airflow are expected to deliver a 5% increase in CADR compared to the previous comparative solution.

What do you gain?

• Efficient air purification in the room.
• Effective air circulation through the filtration system.
• Reducing the amount of fine dust and airborne allergens.
• Convenience of daily use without having to manually control each setting.

🏠 HOW MUCH M² IS DREO 337S ENOUGH?

In the case of air purifiers, it is worth paying attention not only to the maximum declared area, but also to the number of air exchanges per hour.

Dreo 337S offers two important parameters:

Up to 99 m² – at ACH 1

This means about one theoretical air exchange per hour under the conditions adopted by the manufacturer.

About 21 m² – at ACH 4,8

This means about 4,8 theoretical air exchanges per hour, which corresponds to more intensive purification.

If you want to effectively reduce fine dust in a daily room, it is worth following the area of about 21 m² at ACH 4,8.

Actual efficiency also depends on the height of the room, the setting of the device, air flow and sources of pollution.

🛡 TRUE HEPA H13 FILTER – EFFECTIVE PROTECTION AGAINST FINE PARTICLES

Dreo 337S uses a three-stage filtration system, the key element of which is the HEPA H13 filter.

According to the manufacturer’s declaration, the filter captures 99,97% of particles with a size of at least 0,3 µm under certain test conditions.

Thanks to this, the device helps to reduce the amount of such impurities as:

• dust and fine dust particles,
• pollen of plants,
• epidermal particles and allergens of animal origin,
• fine smoke particles,
• suspended particulate matter PM2.5.

Important: the effectiveness of the filter itself does not mean that 99,97% of all impurities are removed from the entire room. The effect also depends on the performance of the device, working time and environmental conditions.

CLEANER AIR IN THE HOME WITH ANIMALS

Do you love animals, but you are bothered by hair and floating small debris?

The Dreo 337S can be a practical addition to your daily cleaning routine.

The filtration system helps to capture airborne fine particles, including allergens associated with animals.

This solution is especially useful in homes where dogs or cats live.

Remember: The purifier does not replace vacuuming or removing hair from furniture and floors.

🌫 PM2.5 SENSOR – YOU KNOW WHAT AIR YOU BREATHE

Air quality is not always visible to the naked eye.

Therefore, the Dreo 337S is equipped with a PM2.5 sensor, which monitors the concentration of fine particles suspended in the air on an ongoing basis.

The information is presented on the LED display and using the color RGB indicator.

This allows you to easily check whether the air quality is improving or needs more intensive purification.

The PM2.5 sensor measures fine dust, not all types of gaseous pollutants.

🤖 AUTO MODE – THE PURIFIER ADJUSTS THE WORK ITSELF

Don't want to change fan speed all day?

Enable auto mode AUTO.

The Dreo 337S purifier uses information from the PM2.5 sensor to adjust the operating intensity to the current dust concentration.

When the air quality deteriorates, the device can increase the purification speed.

When the particle concentration drops, it can limit the intensity of work.

This is a convenient solution for people who want to use the purifier without constant manual control.

🔇 SLEEP MODE – ONLY 15 DB

An air purifier should help keep you comfortable, not interfere with your rest.

Therefore, the Dreo 337S is equipped with Sleep mode, in which, according to the manufacturer, the noise level can be as low as 15 dB.

This is especially important in rooms where silence is important.

It will work during:

• night rest,
• work at the computer,
• science,
• reading a book,
• relaxation in the bedroom.

Actual volume depends on the selected mode and measurement conditions.

📱 WI-FI CONTROL – CONVENIENCE WITH THE DREO APPLICATION

Modern air purification is also convenient operation.

Dreo 337S works with the Dreo application, thanks to which you can control the device using a compatible smartphone.

The application allows, among others:

• checking information on air quality,
• changing the settings of the purifier,
• convenient management of the device operation.

The model also works with Amazon Alexa and Google Home, enabling integration with a compatible smart home system.

The availability of individual functions depends on the configuration of the application, network and supported system.

🔄 SMART CARE – FILTER REPLACEMENT REMINDER

Even a good purifier requires regular maintenance.

Over time, the filter accumulates impurities and needs to be replaced.

Therefore, Dreo 337S uses the Smart Care system, which monitors filter consumption and informs about the need to replace it.

It is a convenient solution that makes it easy to ensure proper operation of the device.

Regular filter replacement according to the manufacturer's instructions helps maintain cleaning efficiency.

🌿 AIR PURIFICATION THROUGHOUT THE YEAR

Dreo 337S can be useful regardless of the season.

Spring – helps to reduce the amount of pollen floating.

Summer – supports the purification of air from dust and fine particles.

Autumn – is useful when staying in closed rooms more often.

In winter – helps to reduce the concentration of suspended dust that can enter the house along with external air.

The purifier does not replace ventilation or removal of sources of contaminants.

WHAT ABOUT SMELLS AND LZO (VOC)?

A multi-stage filtration system can help reduce some of the unpleasant odors and selected gaseous pollutants if the cartridge used contains an appropriate sorption layer.

The HEPA H13 filter itself is primarily responsible for retaining particulate matter, not gases and volatile organic compounds.

Therefore, the effectiveness of odor reduction and VOC depends on the design and properties of the entire filter cartridge.

In the case of intense fumes or smoke, it is also necessary to remove the source of pollution and adequate ventilation.
