H14 TRUE HEPA · LARGE ROOM AIR PURIFIER
H14 True HEPA.
Made for larger living spaces.
CUCKOO CAC-D2020FW
The CUCKOO H14 True HEPA Large Room Air Purifier (CAC-D2020FW) has a rated coverage area of 66 m². Four-stage filtration combines particle capture with a separate activated carbon deodorisation layer, while 360° air intake and Auto mode support everyday air care.
Check detected air quality with the six-colour indicator and PM10, PM2.5 or PM1.0 display. Choose Auto for sensor-based fan adjustment or Sleep mode for lower airflow and reduced lighting.
*Rated coverage follows the Australian manual. Actual performance varies with room conditions, operating mode and filter condition.

360° intake.
Cleaned air flows upwards.
The perforated cylindrical body draws air in around the unit. Air passes through the filter system before returning to the room through the top outlet.
With a rated coverage area of 66 m², the CAC-D2020FW suits larger everyday indoor spaces.
Keep the inlet and outlet clear and follow the manual’s placement instructions. An air purifier does not replace ventilation.
FOUR STAGES. DIFFERENT ROLES.
H14 at the heart.
Four layers working together.
The CUCKOO CAC-D2020FW combines a pre-filter, allergen filter, H14 True HEPA filter and activated carbon deodorisation filter.
Particle filtration and odour reduction have different jobs. The HEPA stage captures fine airborne particles, while activated carbon helps reduce everyday odours.
Pre-filter
Captures larger particles such as dust, hair and pet fur. Remove and clean this reusable outer layer regularly.
Allergen filter
A separate functional filter helps capture airborne allergenic substances. Replace it rather than washing it.
H14 True HEPA filter
Helps capture fine airborne particles such as fine dust, pollen and smoke particles as air passes through the filter.
Activated carbon filter
Helps reduce everyday household odours. This deodorisation layer is distinct from the HEPA particle filter.
PARTICLE FILTRATION & ODOUR REDUCTION
High-efficiency filtration.
For the particles you cannot see.
The CAC-D2020FW uses H14 True HEPA filtration to help capture fine airborne particles as air passes through its filter. The HEPA stage is intended for airborne particles such as fine dust, pollen and smoke particles; the carbon layer has a separate odour-reduction role.

A SIMPLE FILTER-CARE ROUTINE
Meet the pre-filter.
The outer mesh you can wash.
The pre-filter is the thin, removable mesh wrapped around the outside of the cylindrical filter. It catches larger particles such as dust, hair and pet fur before they reach the inner layers. Peel off this outer mesh for cleaning — do not wash the complete cylinder.
The schedule below follows the Australian manual. Actual intervals vary with use and environment.
- RemoveSwitch off, unplug and detach the outer pre-filter.
- CleanGently remove dust, or wash the detached mesh in lukewarm water.
- Dry & refitDry completely in the shade before wrapping it back around the filter.
Washable: detached pre-filter only. Do not wash the allergen filter, H14 HEPA / activated carbon main filter, or the purifier body.
| Pre-filter | Clean every 2–4 weeks. Remove dust gently or wash the detached pre-filter, then dry completely in the shade. |
|---|---|
| Allergen filter | Replace approximately every 4 months. Do not wash. |
| Ultra-Deo PM2.5 main filter | Replace approximately every 12 months. This is the main H14 HEPA / activated carbon filter assembly. Do not wash. |
| Fine dust sensor | Clean every 1–2 months as instructed in the manual. Do not use alcohol or acetone. |
| Exterior & top outlet | Clean every 2–4 weeks. Follow the manual when removing and refitting the top grille. |
Use genuine CUCKOO filters. Do not reuse a wet or damaged inner filter, and check that the filter’s top faces upwards when refitting.

CAC-D2020FW air purifier FAQs
What does the H14 True HEPA filter do?
The H14 True HEPA stage helps capture fine airborne particles, including fine dust, pollen and smoke particles, as air passes through the filter. Activated carbon has a separate role in helping reduce everyday odours. Performance depends on room conditions, airflow and filter condition.
Is the CAC-D2020FW suitable for a large living room?
Its rated coverage area is 66 m², making it an option to consider for a larger room. Check your room dimensions and the manual’s placement guidance. Room layout, ceiling height, operating mode and filter condition affect results; the rating does not guarantee the same performance in every open-plan space.
Can it help filter airborne dust, pollen and smoke particles?
The H14 HEPA stage helps capture fine airborne particles as air passes through the filter. Activated carbon helps reduce everyday odours. Particle filtration does not mean removal of every gas or pollutant; use appropriate source control and ventilation alongside air cleaning.
Where can I get replacement filters for CAC-D2020FW?
View the CAC-D2020FW replacement filter options or the 1-year filter replacement bundle. The bundle lists one pre-filter, three allergen filters and one H14 HEPA/carbon assembly. Select the required filter type and check availability on its product page.
What should I do before first use?
Unplug the unit, open the filter cover and remove all plastic wrapping from the filter. Refit the filter with its top facing upwards, replace the cover securely, then connect the power. Do not operate without the filter correctly installed.
Can I wash the complete cylindrical filter?
No. Only the removable pre-filter can be washed. Fully dry it before refitting. Replace the allergen filter and the main Ultra-Deo PM2.5 filter assembly according to the manual; do not wash them.
How do I check PM1.0, PM2.5 or PM10?
Press AIR CLEANLINESS during operation to cycle through PM10, PM2.5 and PM1.0. The corresponding concentration is displayed for five seconds.
Can I turn the colour ring off?
Yes. Hold AIR CLEANLINESS for at least three seconds to switch the indicator on or off. Sleep and Baby modes turn it off by default after their initial display period.
How do I change the voice guide to English?
In standby, hold MODE for at least three seconds to enter language settings. Use FAN SPEED to select En for English, then press ON/OFF to save. The manual also provides Spanish, Korean and Chinese options.
Is the plasma ionizer always on?
It has a separate on/off control through the STERILIZATION button. The manual also states that Baby mode activates the ionizer. Refer to the mode and control instructions when selecting your preferred settings.
Why does the colour stay the same?
The surrounding air may be stable, or the sensor may need cleaning. Follow the manual’s fine-dust sensor cleaning instructions. If the reading remains abnormal, contact CUCKOO Support.
Can it replace ventilation or a kitchen extraction hood?
No. Use it as an indoor air purifier alongside appropriate ventilation. It is not a carbon monoxide safety device or a replacement for a kitchen extraction system.
