About this equipment
The HEPA 1000 provides large-capacity air scrubbing for bigger work areas and projects that need additional filtration capacity.
Plan the HEPA air scrubber request
Describe the space, project activity, occupied-area considerations, timing, and any other air-moving or filtration equipment on site. For a smaller or more portable option, review the HEPA 500 commercial air purifier.
HBS confirms the rental arrangement, availability, rates, requested period, and fulfillment details. Equipment selection for mold-related work must remain consistent with the project’s containment, remediation, and safety requirements; an air scrubber is not a substitute for source removal or professional remediation.
Unit details
The HEPA 1000 is a large-capacity commercial air scrubber rated at 1000 cubic feet per minute (CFM) with two-stage filtration: a pre-filter for larger dust and a HEPA filter for fine particles. It is the right choice for larger rooms, open floor plans, demolition dust, and commercial spaces.
Air scrubber or air purifier?
Both units filter the air through HEPA filters. The HEPA 1000 moves about twice the air of the HEPA 500, so one unit can cover a bigger space or clean the air faster. For a single room in an occupied home, the HEPA 500 is often enough.
Two HEPA 500 units add up to the same rated airflow as one HEPA 1000. Two smaller units can sit in separate rooms; one HEPA 1000 is simpler where the space is open or one containment needs a single exhaust.
Jobs that call for 1,000 CFM
- Open-plan living, dining and kitchen areas where dust from one end reaches the other.
- Whole-floor remodels, flooring tear-outs and drywall demolition.
- Commercial suites, offices and other spaces with larger air volumes.
- Contained work areas that need a negative-air exhaust, described below.
Sizing the HEPA 1000
The IICRC's equipment worksheet sizes air filtration devices with cubic feet × air changes per hour ÷ 60 = CFM.
At its rated 1,000 CFM, the HEPA 1000 moves 60,000 cubic feet of air an hour. That gives four air changes per hour in about 15,000 cubic feet, or six in about 10,000 cubic feet, such as a 1,250 square foot open floor with 8-foot ceilings. The sizing guide walks through the math.
More air changes clear dust faster. The CDC's purge table for an empty, well-mixed room shows 99 percent of airborne particles cleared in about 69 minutes at 4 air changes per hour, 46 minutes at 6 and 28 minutes at 10.
The CDC notes that real rooms mix less evenly, so plan on longer, and leave margin in your sizing because airflow drops as filters load.
Setup tips
- Size the unit with the formula in the questions below and leave some margin, because airflow drops as filters load.
- To keep dust inside a work area, set the scrubber up to exhaust filtered air out of the contained space.
- Check the pre-filter during long jobs and tell HBS if the unit needs a filter change.
- Keep the intake clear of plastic sheeting, debris piles and walls.
- If the floor is wet, plug into a GFCI-protected outlet; OSHA's cleanup guidance says GFCIs must be used in all wet locations.
Setting up negative air with an AFD
These steps follow EPA's containment guidance for mold remediation and its lead-safe work steps:
- Seal the work area with plastic sheeting and close and seal its doors. EPA's lead-safe steps add an airlock at the entry: one sheet of plastic taped on all four edges and slit down the middle, with a second sheet taped along the top as a flap over the slit.
- Turn off forced-air heating and cooling, and cover the vents in the work area with plastic.
- Place the scrubber inside the containment and duct its exhaust out of the work area, to the outdoors where possible. EPA describes a HEPA-filtered fan unit exhausted outside the building.
- Make sure replacement air can get into the space. EPA calls this adequate makeup air.
- Check the plastic. EPA says it should billow inward on all surfaces; if it flutters or billows outward, containment has been lost and has to be fixed before work continues.
- Keep the unit running through the work and the cleanup. EPA recommends a HEPA vacuum for final cleanup.
Tell HBS the size of the containment and the exhaust run when you request the unit, so the ducting can be confirmed in your quote.
Two-stage filtration and filter care
The pre-filter catches larger dust before it reaches the HEPA filter, which keeps the HEPA stage working longer. EPA notes that all air cleaners need periodic cleaning and filter replacement to work properly. A loaded pre-filter cuts airflow, so check it on dusty jobs and call HBS before it clogs.
Your written quote itemizes any filters or accessories. Every HBS unit is cleaned and decontaminated after each rental; tell HBS what work the unit ran on when you return it.
Lead, mold and contaminated-water jobs
Lead. EPA says homes built before 1978 may have lead-based paint. Its Renovation, Repair and Painting rule requires contractors paid for renovation in those homes to be lead-safe certified.
The rule generally does not cover homeowners working on their own home, but it does apply if you rent out all or part of the home or renovate homes to sell. An air scrubber supports lead-safe work practices; it does not replace them.
Mold. EPA points homeowners to its professional remediation guidance when mold covers more than about 10 square feet, and says not to run an HVAC system you know or suspect is contaminated with mold.
Contaminated water. Under the IICRC S500 standard, sewage, a toilet backflow and outside floodwater or storm surge are Category 3 water, and a washing machine or dishwasher overflow is Category 2; the CDC warns that floodwater may contain sewage.
Those jobs, and any structural or electrical hazard, go to an appropriate experienced professional. HBS does not offer mold remediation or contaminated-water cleanup, and neither a rental nor HBS's water-only drying includes restoration or repairs. For a clean-water leak, ask HBS about its separately scoped water-only drying at (772) 677-1735.
Equipment that pairs with the HEPA 1000
- HEPA 500 air purifier for a second room or a smaller side area.
- Commercial dehumidifier and air movers when wet materials are being dried at the same time.
- Moisture meter to confirm materials are dry before they are closed up.
Restoration contractors and remodelers can review contractor equipment rentals for multi-unit jobs.

Common questions
Is an AFD rental the same as an air scrubber rental?
AFD stands for air filtration device. HBS uses this term for its HEPA air-filtration equipment, including this air scrubber. It filters airborne particles; it does not dehumidify a room. Confirm airflow, filters and any required ducting for the specific work.
How do I size an air scrubber?
Multiply the room's length, width, and ceiling height to get cubic feet, multiply by the air changes per hour you want, then divide by 60 for the CFM needed. At its rated 1000 CFM, one HEPA 1000 delivers 6 air changes per hour, which Legend Brands' guidance names as the general minimum for an air scrubber, in about 10,000 cubic feet, or 4 in about 15,000 cubic feet.
Can the air scrubber create negative air pressure?
Yes, when it is set up with ducting that exhausts filtered air out of the work area, an air scrubber can help keep dust inside a contained space. HBS can talk through the setup when it confirms your rental.
What does HEPA filtration capture?
A true HEPA filter is designed to capture at least 99.97 percent of particles 0.3 microns in size. The HEPA 1000 pairs it with a pre-filter that catches larger dust first.
Should I rent one HEPA 1000 or two HEPA 500 units?
They add up to the same rated airflow. Two HEPA 500 units can sit in separate rooms; one HEPA 1000 is simpler for an open space or a single containment with one exhaust.
How do I know a negative-air setup is working?
EPA's containment guidance says the plastic sheeting should billow inward on all surfaces. If it flutters or billows outward, containment has been lost; fix the seal, the exhaust or the makeup air before work continues.
What should I do when the pre-filter gets dirty?
Call HBS before it clogs. A loaded pre-filter cuts airflow, and EPA notes that all air cleaners need periodic cleaning and filter replacement to work properly. Your written quote itemizes any filters or accessories.
Can the HEPA 1000 remove mold?
No. An air scrubber filters airborne particles during work; it does not remove mold from materials or replace remediation. If you see mold growing, call an appropriate experienced professional; EPA recommends professional help for mold covering more than about 10 square feet, and HBS does not offer mold remediation.
