Filter System

Filtration Technology

The Purisystems 900 CFM uses a 3-stage filtration system: a pre-filter captures large particles like dust, debris, and pet hair before they clog the main filters; a True HEPA filter traps 99.97% of airborne particles down to 0.3 microns including mold spores, pollen, and fine dust; and an activated carbon filter absorbs VOCs, smoke, chemical fumes, and odors. This multi-stage approach gives it an edge over single-filter consumer units, particularly in environments with both particulate and gaseous contaminants common on restoration and construction sites.

CADR & Sound

Noise & Performance

At 900 CFM, this air scrubber moves significantly more air than residential purifiers, which typically max out at 200-400 CFM. The 5-speed settings allow you to scale airflow from lower speeds suitable for occupied spaces to maximum output during active remediation.

Customer feedback is split on noise , some find it surprisingly quiet for a commercial unit, while others note it runs loud at higher speeds, which is expected for this class of equipment.

Connectivity

Smart Features & Controls

This is a no-frills commercial unit with manual 5-speed controls and an air quality indicator , there is no WiFi, no app, and no voice assistant compatibility. What it does have is a built-in GFCI outlet that lets you daisy-chain units or power tools safely on job sites, which is far more valuable in its intended commercial environment than smart home features.

The filter change indicator takes the guesswork out of maintenance scheduling.

Upkeep

Filter Maintenance

The pre-filter captures large debris and extends the lifespan of the HEPA filter, and it should be checked and cleaned regularly especially in heavy-dust environments. The HEPA and activated carbon filters need periodic replacement based on usage intensity , expect more frequent changes during active remediation versus general air maintenance.

The built-in filter change indicator alerts you when replacement is due, removing guesswork from the maintenance schedule.

Who Is This Air Purifier For?

Ideal For

  • Restoration contractors handling mold, water damage, or fire cleanup who need negative air pressure and high-volume HEPA filtration
  • Construction crews needing dust control during drywall, sanding, or demolition work on OSHA-compliant job sites
  • Commercial facility managers dealing with large open spaces that need aggressive air scrubbing after renovations or contamination events
  • Pet-related businesses like grooming shops or boarding facilities where activated carbon filtration handles persistent odors and airborne dander

Not Ideal For

  • Homeowners wanting a quiet bedroom purifier , this commercial unit prioritizes airflow over whisper-quiet operation
  • Smart home enthusiasts who expect app control, scheduling, or voice assistant integration , this is manual-only
  • Anyone needing a compact, set-it-and-forget-it home purifier , the size, weight, and manual controls are built for professional use

Setup is straightforward , remove the unit from packaging, install the pre-filter, HEPA filter, and activated carbon filter in the correct order per the manual, plug in, and select your speed. No tools required for filter installation.

Run the unit on maximum speed for the first 30-60 minutes in a new space to establish initial air scrubbing before dialing back to a maintenance speed

Position the unit so the intake faces the contamination source for negative air pressure applications

Purisystems backs this air scrubber with a 1-year limited manufacturer's service warranty. For commercial use with heavy daily operation, verify coverage terms directly with Purisystems as warranty conditions may vary based on application.

FAQ

Can the Purisystems 900 CFM air scrubber be used for mold remediation?

Yes, this is one of its primary use cases. The HEPA filter captures mold spores down to 0.3 microns, and when set up as a negative air machine, it creates negative pressure to prevent cross-contamination between affected and clean areas.

Customer feedback specifically mentions effectiveness in reducing mold spores.

How loud is this air scrubber at different speeds?

Customer feedback is mixed , some users find it surprisingly quiet for a 900 CFM commercial unit, while others say it's loud on higher speeds. At lower speeds it's more manageable for occupied spaces, but at maximum output expect significant noise typical of commercial air moving equipment.

It's not designed for quiet bedroom use.

How often do the HEPA and activated carbon filters need to be replaced?

Filter lifespan depends on usage intensity and contaminant levels. In heavy-use scenarios like active construction or remediation, the HEPA filter may need replacement every few months.

The pre-filter should be inspected weekly in dusty environments. The built-in filter change indicator alerts you when replacement is needed.

Can you stack multiple Purisystems air scrubbers together?

Yes, the stackable design is a key feature for commercial users who need multiple units on a job site. The units are engineered to stack securely, saving floor space.

The built-in GFCI outlet also lets you daisy-chain power between stacked units safely.

Is this air purifier suitable for home use in a large room?

While it can physically clean air in a large room, this is a commercial-grade air scrubber designed for job sites and industrial applications. At 46.5 lbs and 31.89 inches wide with no auto mode or smart features, most homeowners would be better served by a residential air purifier with quieter operation and automated controls.

Does the Purisystems 900 CFM meet job site safety requirements?

Yes, it includes a built-in GFCI outlet and carries both UL certification and OSHA compliance. These certifications make it suitable for professional use on construction sites, restoration projects, and other commercial environments where electrical safety standards must be met.
