Filter System

Filtration Technology

The ORANSI mod+ uses a 3-stage filtration system: a pre-filter for large particles like hair and dust, a True HEPA particle filter capturing 99.97% of airborne particles down to 0.3 microns, and an activated carbon filter that absorbs VOCs, smoke, and odors. This combination handles everything from pollen and pet dander to wildfire smoke and cooking smells , a more complete filtration stack than many competitors that skip the carbon stage or use thin carbon sheets instead of a dedicated filter layer.

CADR & Sound

Noise & Performance

With a dust CADR of 363 CFM, the mod+ delivers 4.8 air changes per hour in its rated 1,361 sq ft coverage area , well above the 4x/hour threshold recommended for allergy relief. At its lowest setting, it produces just 28 dB of noise, quieter than a library and easily suitable for bedrooms or offices.

The dedicated sleep mode further optimizes for minimal noise and dims any indicator lights for undisturbed rest.

Connectivity

Smart Features & Controls

The mod+ takes a deliberately simple approach with manual fan speed controls and a dedicated sleep mode , no WiFi, no app, no auto mode. This means no firmware updates or connectivity issues, but it also means you cannot schedule operation remotely or have the unit respond automatically to changes in air quality.

For users who prefer tactile controls and straightforward operation, this is a strength; for those wanting Alexa or Google Home integration, it is a clear gap.

Upkeep

Filter Maintenance

Replacement filters (Mod Plus model) last approximately 12 months under normal use, which is above average for this class , many competing large-room purifiers require filter changes every 6 to 9 months. The unit includes a filter change indicator to take the guesswork out of replacement timing.

The pre-filter stage catches larger debris first, extending the HEPA filter's effective life and keeping ongoing maintenance costs lower.

Can the ORANSI mod+ handle wildfire smoke?

The mod+ is well-suited for wildfire smoke. Its True HEPA filter captures fine smoke particles down to 0.3 microns, while the activated carbon filter absorbs smoke odor and VOCs.

The high 363 CFM CADR means it cleans air quickly even in large rooms during smoke events.

Does the ORANSI mod+ work with Alexa or Google Home?
