DREO 338S DR-HAP008S Smart Air Purifier with PM2.5 Monitor and Wi-Fi

A real-time PM2.5 monitor shows changing indoor air conditions, while Auto mode adjusts the purifier’s speed to match. The DREO 338S DR-HAP008S is designed to help manage airborne particles and household odours in bedrooms and living spaces.

Its 3-in-1 filter combines a pre-filter, a high-efficiency filter and activated carbon to capture particles such as dust, pollen and smoke. The carbon layer also helps reduce household odours.

Control it from the app, by voice or with the unit’s touch controls. Sleep mode turns off the display lights, making it easier to keep the purifier running in a bedroom overnight.

How it fits

For room coverage, the figures describe two different air-change rates: AHAM-verified performance gives a CADR of 115 CFM and refreshes air every 12.4 minutes in rooms up to 178 sq. ft. at 4.8 air changes per hour. Based on one air change per hour, coverage is up to 856 sq. ft. This context helps you compare the purifier with a model intended for a different room size or air-refresh rate.

In a bedroom, Sleep mode turns off the display lights, while the stated noise level is 24 dB. For everyday household changes—such as cooking odours, dust or smoke—the PM2.5 sensor monitors air quality in real time, and Auto mode increases or reduces fan speed as conditions change. Turbo, Normal and Sleep modes offer additional ways to set operation to the situation.

Why it makes sense

The app supports remote control, scheduling and 30-day air-quality reports, so you can manage operation and review PM2.5 trends without relying only on the purifier’s display. The display shows AQI levels, and a four-colour indicator provides a quick visual cue. Voice control works with Alexa and Google Assistant.

Customers commonly describe the air as fresher after using the purifier and appreciate its quiet operation and straightforward controls. These impressions complement practical features such as the sensor and automatic mode, which make it easier to follow changing indoor conditions without repeatedly adjusting the fan by hand.

It’s a good fit if you want one purifier for particle filtration, odour reduction and app-based control. The built-in aroma pad can also be used with essential oils for a chosen fragrance, oils are not included.
