DREO air purifier DR-HAP008S

A purifier with app controls and live air-quality readings suits a different need from a basic unit you switch on and leave alone: it gives you more ways to track and adjust its operation. The DREO DR-HAP008S combines a PM2.5 sensor, automatic mode and a three-part filter for particles and household odours. Its room-coverage figures need a little context, though: the rating for more frequent air changes is for a smaller space than the figure based on one air change per hour.

Key specifications

The purifier has an AHAM-verified CADR of 115 CFM. DREO states coverage of up to 178 sq. ft. at 4.8 air changes per hour (ACH), or up to 856 sq. ft. at 1 ACH. Those figures describe different refresh rates, so the larger area should not be read as equivalent to the more frequent cleaning rate.

Its three-in-one filter combines a pre-filter, high-efficiency filter and activated carbon layer. The product information says it captures fine particles such as PM2.5, pollen, dust and smoke, and helps reduce household odours. A built-in sensor tracks PM2.5, while the display shows AQI readings from 1–999 and a four-colour indicator offers a quick visual cue.

Auto, Turbo, Sleep and Normal modes are available, with four adjustable speeds. Sleep Mode turns off the display lights. App control includes air-quality reports, scheduling and filter-life reminders, Alexa and Google Assistant voice control are also listed. A 12-hour timer is available on the unit. ENERGY STAR certification and approximate annual use of 125 kWh are stated in the product information.

Who it’s for

It’s a good choice if you want a bedroom or home purifier that can respond to changing readings, rather than a basic fan-and-filter setup with fewer monitoring and control options. For example, you could check the AQI display after cooking or opening a window, then use Auto mode instead of choosing a speed each time. The listing also names pets, smoke, dust, pollen and odours as intended concerns, that doesn’t mean it removes every source of odour or replaces other ways of managing indoor air.

It may not be the best choice if you need a clearly stated high air-change rate across a large open-plan area. The 856 sq. ft. figure is based on 1 ACH, while the 4.8 ACH coverage is 178 sq. ft. Filter upkeep is another consideration: the app and indicator provide replacement reminders, and DREO recommends its original replacement filter for compatibility.

Everyday use

The app offers 30-day air-quality reports and scheduling, while the purifier’s sensor adjusts fan speed automatically in Auto mode as readings change. That may suit someone who wants less day-to-day adjustment, someone who prefers a simple manual control and no connected features may have little use for the added monitoring. Sleep Mode switches off the display lights, and the built-in aroma pad can hold essential oils, which are not included.

The product description also mentions a spiral airflow design and quieter operation, but gives no specific noise level. Without having tested it, I wouldn’t treat “quiet” as a guarantee of near-silent operation, especially if you plan to run a higher speed while sleeping.

Three practical questions

Can I see air-quality readings on the unit? Yes. The PM2.5 sensor and display show AQI values from 1–999, with a coloured indicator for a quick visual reference.

Can I control it without using the app? The listing includes a 12-hour timer on the unit, as well as voice control through Alexa and Google Assistant. App features include scheduling and reports.

Are essential oils included? No. The purifier has a built-in aroma pad, but the oils are not included.

Veredicto final

Choose the DR-HAP008S if you value live PM2.5 monitoring, automatic speed adjustment and connected controls, and its 178 sq. ft. rating at 4.8 ACH suits the room you have in mind. If you’re sizing it for a larger space, decide whether one air change per hour is enough for your needs before relying on the 856 sq. ft. figure. That coverage distinction, plus the need to replace the filter over time, matters more than the extra modes if your main priority is straightforward room coverage.
