Filter System

Filtration Technology

The Holmes HAP706-NU-1 uses a certified True HEPA filter that captures 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, and pet dander. A washable pre-filter traps larger particles like hair and lint before they reach the HEPA stage, extending the main filter's lifespan.

The optional ionizer adds a supplemental layer by charging particles so they cling to surfaces, though it lacks an activated carbon stage found in purifiers designed for odor and gas removal.

CADR & Sound

Noise & Performance

With a dust CADR of 55 CFM and 80 sq ft coverage, this purifier delivers roughly 4 air changes per hour in a small room , adequate for maintaining clean air in a bedroom or office. The minimum noise level sits at 55 dB, which is comparable to a running refrigerator and louder than many competitors' low settings.

At higher speeds the noise increases further, making this better suited for daytime use or spaces where background noise is acceptable.

Connectivity

Smart Features & Controls

Controls are entirely manual with a simple 3-speed dial , no touchscreen, no WiFi, no app integration, and no auto mode that adjusts fan speed based on air quality. There is no timer function or air quality indicator, so you set it and leave it running.

This straightforward approach keeps the tier low and eliminates connectivity issues, but it does mean you cannot monitor or control it remotely.

Upkeep

Filter Maintenance

The washable pre-filter can be rinsed and reused, which helps reduce ongoing costs and keeps the HEPA filter working efficiently longer. The True HEPA filter itself will need periodic replacement , Holmes recommends checking it regularly and replacing when visibly dirty or airflow diminishes.

Look for replacement filters compatible with the HAP706-NU-1 model for exact fit.

FAQ

What size room does the Holmes HAP706-NU-1 air purifier cover?

The Holmes HAP706-NU-1 is designed for small spaces up to 80 sq ft, making it ideal for bathrooms, home offices, or small bedrooms. For larger rooms, you would need a purifier with a higher CADR rating or consider using multiple units.

Does the Holmes True HEPA mini tower remove odors and smoke?

This purifier does not include an activated carbon filter, so it is not effective at removing smoke, cooking odors, or chemical gases. It excels at capturing particles like dust, pollen, and pet dander through its True HEPA filter, but odor removal requires a carbon filtration stage.

How loud is the Holmes HAP706-NU-1 air purifier?

The minimum noise level is 55 dB, roughly equivalent to a quiet conversation or a running refrigerator. Customer feedback is mixed , some find it acceptable as white noise, while others consider it too loud for sleeping.

If quiet operation is a priority, this may not be a strong option for choice for a bedroom.

How often do I need to replace the filter in the Holmes HAP706-NU-1?

The washable pre-filter can be rinsed and reused indefinitely, while the True HEPA filter needs replacement when airflow noticeably decreases or it appears visibly dirty. Replacement frequency depends on usage and air quality, but checking it every 3-6 months is a good practice.

Does this air purifier work with Alexa or Google Home?

No, the Holmes HAP706-NU-1 has no WiFi connectivity, app control, or voice assistant integration. It operates with manual controls and a 3-speed dial only.

Is the Holmes HAP706-NU-1 good for allergies and pet dander?
