What this purifier handles in a bedroom or living room
- Room size, fan noise and how the sensor behaves are the main things to weigh before buying.
- Sleep mode runs as low as 15 decibels, so it's worth deciding whether night operation matters to you.
- The aromatherapy box uses pads, and three are included in the box.
This Dhyala model is built for airborne upkeep in a large space, with a dual-sided intake feeding two three-stage filter sets. Each set pairs a pre-filter, a HEPA layer and an activated carbon layer, so the unit is set up to catch pet hair along with finer particles and household odors.
The airflow figure is 265 CFM, and the brand rates coverage up to 3000 square feet in one hour. A PM2.5 sensor reads the room in real time and adjusts fan speed on its own, while four manual speeds and a 1 to 12 hour timer let you set the pace yourself.
We'd consider this a sensible pick for an open living area or a large bedroom where you want one unit to do the work. Sleep mode drops the sound level to 15 decibels, and the aromatherapy box takes one of the three included pads if you want a light scent in the room.
What the $99.99 price actually means
The current price is $99.99, which is $29.88 less than the typical price over the last 90 days of $129.87. It also matches the lowest price on record in the all-time window, so this is about as low as it has gone.
The two pre-filters can be washed and reused after drying, which trims some of the upkeep cost, but the HEPA and carbon layers inside are the parts that eventually need replacing. The unit has a filter replacement indicator that tells you when to swap them, though the replacement price and interval aren't stated here.

Placement, cleaning and filter upkeep
Leave clearance around the intake grilles so the dual-sided design can pull air from both the front and rear, and keep the unit on a level surface since it shuts off if tilted past 45 degrees. The 1.83 meter anti-chew cord gives you some slack for floor placement near a wall.
The washable pre-filters are the routine maintenance item, and they need to be fully dry before they go back in. The app and voice control through Alexa and Google Assistant handle day-to-day operation, including the timer and fan speed.
Before buying, check the price and availability of the replacement filter set and how often the brand recommends changing it, since that is the real long-term cost of running this purifier.
When this purifier is the wrong fit
Skip it if you need to cover more than one large room, since the 265 CFM airflow is sized for the single space where the unit sits. A whole-home setup would need a different approach.
Also pass if you want to manage everything from the purifier itself with no app or voice assistant involved, or if you'd rather not deal with recurring filter purchases. For a small bedroom, the coverage here is more than you need.
