Filtration Technology

The DAYETTE AP401 uses a 4-stage filtration system anchored by a medical-grade H14 HEPA filter, which captures 99.95%+ of particles at 0.3 microns , a meaningful upgrade over the H13 standard (99.97% at 0.3 microns) found in most consumer purifiers. The pre-filter catches larger matter like pet hair and dust, while the activated carbon layer absorbs VOCs, smoke, and cooking odors.

This combination makes it effective against both particulate and gaseous pollutants, a setup that typically costs more in competing large-room models.

CADR & Sound

Noise & Performance

With a CADR upgraded to 500 m³/h, the AP401 delivers powerful purification across rooms up to 3000 sq ft , enough for whole-house coverage in many homes. At its lowest setting, the unit runs at just 22 dB, which is virtually inaudible and well below the 30 dB threshold that roughly a third of purifiers achieve.

While maximum noise specs aren't published, customers report the low fan setting is nearly inaudible, and multiple speed settings including Turbo Technology allow you to balance airflow and noise for bedroom or living room use.

Connectivity

Smart Features & Controls

The AP401 includes a built-in air quality monitor that provides real-time readings, paired with an auto mode that adjusts fan speed based on detected air quality levels , a genuinely useful feature for hands-off operation. Controls include a remote for convenience, dedicated sleep mode that dims the display and minimizes noise, and a timer function.

What's notably missing is any WiFi or app connectivity, so there's no smartphone control or integration with smart home ecosystems.

Upkeep

Filter Maintenance

Replacement filters use model B0BFDLDKZ1 and should be changed according to the filter change indicator light, which takes the guesswork out of maintenance timing. The washable pre-filter extends the life of the main HEPA filter by catching larger particles before they reach the finer stages.

Customers report the unit is easy to disassemble for filter changes, with a straightforward process that doesn't require tools.

FAQ

What's the difference between H14 and H13 HEPA filters in air purifiers?

H14 HEPA filters capture 99.95% of particles at 0.3 microns, while H13 captures 99.97%. The key advantage of H14 is that it's tested to a stricter standard used in medical and cleanroom settings.

The DAYETTE AP401's H14 filter provides hospital-grade air purification that's particularly beneficial for severe allergy sufferers.

Can this DAYETTE purifier actually cover 3000 sq ft effectively?

The 500 m³/h CADR rating supports the 3000 sq ft coverage claim for at least one air change. Customer feedback confirms effective purification in living spaces around 1700+ sq ft. For faster air changes in large rooms, running the unit on higher speed settings or positioning it centrally will maximize coverage.

How quiet is the DAYETTE AP401 at night for bedroom use?

At its lowest setting, the AP401 runs at just 22 dB , quieter than a whisper and virtually inaudible from across a room. The dedicated sleep mode also dims the display lights so they won't disturb sleep.

Customers confirm the low fan setting is nearly impossible to hear.

How often do I need to replace the filter and how much does it investment?

The AP401 has a built-in filter change indicator that alerts you when replacement is needed, typically every 6-12 months depending on usage and air quality conditions. The replacement filter model is B0BFDLDKZ1.

The washable pre-filter helps extend the main filter's lifespan by catching larger particles first.

Does this air purifier work with Alexa or Google Home?

No, the DAYETTE AP401 does not have WiFi connectivity or smart home integration. It's controlled via the on-unit panel and included remote control.

If smart home compatibility is a priority, you'll need to consider a different model with app connectivity.

Is this purifier good for removing pet odors and dander?

Yes, the 4-stage filtration system is well-suited for pet owners. The pre-filter catches pet hair, the H14 HEPA filter traps fine dander particles, and the activated carbon layer absorbs pet odors.

The high 500 m³/h CADR ensures air cycles through the purifier frequently enough to keep up with ongoing pet-related matter in the room.
