The MOOKA B-D02L is a compact, round HEPA air purifier that suits bedrooms, home offices and other small rooms. It puts a three-layer filter into one cartridge, adds a touch panel on the side and offers four fan speeds, all in a body about 11 inches tall.
This page is built from the brand’s published specifications and policies plus an independent tester’s lab write-up. It is research, not a test run at home.
The short version: it draws little power, and an independent tester measured 40.7 dBA on its Sleep setting. The brand’s own six-air-change room size, though, is only about one fifth of its headline coverage figure. To see MOOKA’s range and check current prices, browse MOOKA’s storefront on Amazon.

What the B-D02L Is
Here are the figures the brand publishes, along with the features that shape daily use.
- Size and weight: 7.1 by 7.1 by 11.1 inches, about 3.6 pounds.
- Colors: white or black.
- Filtration: a pre-filter, an H13 True HEPA layer and an activated carbon layer, all built into one round cartridge.
- Motor: brushless, with a rated draw of 13 watts.
- Fan modes: Sleep, Low, Medium and High.
- Timer: choose from 1, 2, 4 or 8 hours.
- Extras: a child lock, a night light you can switch off and a filter-reset function.
The brand says the H13 layer captures airborne particles down to 0.3 microns, a size range that includes pollen, pet dander, dust and smoke particles.
There is no app, voice control, air quality sensor or Auto mode on this model. You choose a fan speed yourself and, if you like, set a timer.
Filter Layers and Upkeep
The one-piece cartridge works from the outside in. Each of its three layers has a separate job.
- Pre-filter: a nylon mesh, according to the independent tester. It holds back hair, lint and larger dust before they reach the HEPA layer behind it.
- H13 True HEPA: H13 is one of the upper HEPA grades found in household purifiers, and this layer handles the fine particles.
- Activated carbon: aimed at odors and some gases, such as cooking smells and the odor of smoke, which a HEPA layer alone does not hold. The tester described the carbon here as thin and fibrous and tied that to below-average odor and smoke scores.
Plan on a new cartridge every 3 to 6 months, per the brand. Where you land in that range depends on how much the unit runs and on the air in your home, and a household with pets or smoke belongs near the three-month end.
The cartridge is one piece and cannot be washed, so keep it dry. If dust settles on the outside, a soft brush or a vacuum’s brush attachment can lift it, which is a general habit rather than a brand instruction.
A swap takes four moves. Turn the cover left to release its lock and exchange the cartridge, then refit the cover and turn it clockwise until it locks. Finally, with the unit running, keep the fan speed button pressed for three seconds to clear the filter indicator.
The brand cautions against off-brand cartridges, which may not fit snugly or may perform below spec. Air that leaks around a loose cartridge skips the filter, so look for the MOOKA name on any replacement. Alongside the standard cartridge, the B-D02L also has Pet Care and Smoke versions.
What Independent Testing Found
An independent tester ran the B-D02L at top speed for an hour with a particle meter. These are the main results.
- Smaller test room (120 sq ft): the PM2.5 reading went from 100 down to 12.1 µg/m³, an improvement of about 87%.
- Larger test room (194 sq ft): an improvement of 81%.
- Noise: Sleep registered 40.7 dBA, Low 45.9, Medium 52.2 and High 61.1.
- Power use: 2.8 W on Sleep, rising to 15 W on High.
A draw that low makes round-the-clock running a minor concern. The brand advertises a 20 dB Sleep mode, but the tester measured 40.7 dBA, which is a soft hum rather than silence.
The weaker findings matter just as much. The tester gave the B-D02L an overall score of 6.3 out of 10, found odor and smoke removal below average and could not confirm the 135 CFM airflow figure the brand quotes.
Reading the Coverage Claim
Two room-size numbers appear for this model, and they tell very different stories.
- Headline figure: up to 1,076 sq ft, which the brand’s listing ties to one full air change per hour.
- Working figure: 215 sq ft at six air changes per hour, also published by the brand.
The working figure is roughly one fifth of the headline.
A quick way to sanity-check either number is CADR, the Clean Air Delivery Rate: the volume of filtered air a purifier produces each minute, in cubic feet. AHAM, the appliance trade group, suggests a CADR equal to at least two thirds of the room’s floor area.
The brand quotes 135 CFM for this model. That rule points to a room of roughly 200 sq ft, which lines up with the 215 sq ft working figure. The 135 CFM is the brand’s own claim, and the tester could not verify it.
An air change is the whole room’s air passing through the filter once, so a single change per hour is a slow pace. If pollen, smoke or pet dander worry you, treat 215 sq ft as the ceiling: a bedroom or study rather than a large lounge.
Who It Suits and Who Should Skip It
A good match:
- A bedroom, home office, dorm or nursery of up to roughly 200 sq ft.
- A buyer who puts low power use near the top of the list.
A poor match:
- A large open space that needs treating.
- A home where heavy smoke has to be handled.
- Anyone who expects app control or an automatic mode.
MOOKA’s wider lineup offers alternatives for some of those cases. The KJ190L has a washable pre-filter and pulls air in from the front and both sides, while the PR1 brings a PM2.5 readout, Auto operation and a Pet setting. For a desk, the compact M01 runs from a USB-C source and has no built-in battery. None of the models covered here offers an app. You can browse MOOKA’s range through its store on Amazon, and the link opens Amazon.
How It Compares With Levoit
This comparison sets the B-D02L beside the Levoit Core 200S, another compact white cylinder. The figures come from an independent tester’s side-by-side results and the two brands’ published specs.
| Feature | MOOKA B-D02L | Levoit Core 200S |
| Weight | About 3.6 lb | 6.6 lb |
| Warranty | 1 year (tester’s listing) | 2 years |
| App or voice assistant support | No | Yes |
| Filter replacement interval | Every 3 to 6 months | Every 6 to 8 months |
| Quoted airflow (CADR) | 135 CFM | 118 CFM |
| Particle reduction, small test room | 87% | 93% |
| Particle reduction, larger test room | 81% | 91% |
| Sleep-mode noise | 40.7 dBA | 42.1 dBA |
| High-speed noise | 61.1 dBA | 53.9 dBA |
| High-speed power draw | 15 W | 24.6 W |
Levoit cleaned more in both rooms, runs quieter on High and adds app control and a longer warranty. The MOOKA draws less power and weighs about half as much, which makes it easy to carry from room to room.
In the tester’s smoke test, another Levoit model, the Core 300S, cleared smoke in 20 seconds. The MOOKA needed 113 seconds.
If you want a bigger room covered, app control or a longer warranty, shortlist something larger instead. If a small bedroom and low power draw come first, the B-D02L remains a reasonable fit.
Frequently Asked Questions
How long is the warranty?
Get the terms in writing before you rely on one. MOOKA’s store shows no warranty page, and its front page mentions extended coverage without any conditions. The only figure on record is a single year, listed by the tester for this model and echoed by an older manual for a different one. Quote your order number when you ask support what applies to your unit.
What is the return window?
On MOOKA’s own store you can request a return within 30 days of delivery, with postage at your expense. The unit has to be unused, boxed in its original packaging and supported by proof of purchase. Amazon orders run on Amazon’s return policy, so look up that window before you buy.
Does it give off ozone?
The brand says its purifiers are CARB certified, which refers to California’s standard for ozone from air cleaners. The independent tester also reports that the B-D02L has no ionizer or other ozone-producing feature.
How do I use the night light and timer?
With the unit running, hold the top power button for three seconds to switch the night light off or back on. The tester notes that the timer does not start in Sleep mode, so choose Low, Medium or High before setting it. After a filter change, the fan speed button held for three seconds clears the indicator.
Is it a medical device?
No, it is a household appliance. Any health worry about indoor air is a question for your doctor.
The Verdict
The B-D02L is a sensible pick for a small bedroom or home office where low power use and the tester’s 40.7 dBA on Sleep are the priorities. In the tester’s results its cleaning trails a comparable Levoit model, its carbon layer is thin, and it has no app or sensor.
Size it by the brand’s 215 sq ft figure rather than the headline number, and look at a bigger machine if odor or smoke control matters most. Pick a seller with straightforward returns, and hold on to the order number and proof of purchase.
