The Amaircare 4000 VOC Chem with HEPA Airwash Air Purification System is a commercial-grade air scrubber that focuses on particulate and VOCs, gases, and odors. This is a top-quality, heavy-duty portable air purifier for a wide variety of industrial applications: construction & renovation, fire & mold remediation, property rooms & evidence rooms, marijuana dispensaries, welding and print shops, among many others. Coverage for 18,000 ft³ (provides 1 ACH/hr). Comes with a 5-YEAR Limited Warranty on the Motor/Fan and 1 YEAR on All Other Parts Except Filters. The Amaircare 4000 VOC Chem with HEPA focuses on particulate matter and VOCs, gases and odors primarily, and uses the 16" HEPA filter and the 16" Annual Plus Filter Kit, which contains a 7 lb carbon canister for adsorption.
The Amaircare 4000 VOC Chem with HEPA is a commercial-grade air scrubber that puts two strong filters in one all-steel unit: a 100 sq ft Easy Twist HEPA cartridge for fine particles, and a 7 lb carbon canister for VOCs, chemical fumes, gases and odors. When a job creates both dust and fumes, one machine can work on both. Also known as the AirWash, the 4000 is built to provide air filtration for large commercial spaces. Amaircare rates it for 18,000 cubic feet at 1 air change per hour, about 2,250 sq ft with 8 ft ceilings.
Clients put it to work in construction and renovation, fire and mold remediation, property and evidence rooms, marijuana dispensaries, welding and print shops, pharmaceutical settings and many other industrial applications. Its color is white gloss.
Its 24-gauge steel housing has a baked thermoset powder finish that holds up on busy work sites and won’t off-gas chemicals into the air it’s cleaning. Inside, a high-efficiency AC backward curved motor delivers strong airflow while using little electricity, and it’s made for years of continuous operation. Six swivel casters let you roll it where it’s needed without lifting, and the filter section opens from the top with latches, so filter changes are quick and simple. The filters sit protected inside the steel housing, and the Easy Twist design locks the filter canister into place without a struggle.
Air enters through a 6″ round intake with a duct port. Attach rigid or flexible ducting, and the 4000 can draw dust, fumes and odors straight from a workstation, a process or a closed-off area, helping to capture them before they spread through the building. That’s why clients also use it as a fume extractor or source extractor, and for jobs that call for negative or positive air pressure. Clean air leaves through louvers on four of the unit’s six sides, aimed downward, so it spreads evenly through the space.
The variable speed switch lets you match the airflow to the level of contaminants in the space. Run it lower for steady, quieter cleaning, or turn it up when a job is stirring up dust or fumes. It’s rated at about 40.7 dB on low speed and 58.8 dB on high, measured at 6 feet.
With HEPA and carbon working together, the 4000 VOC with HEPA is well suited to mold work. Its HEPA is 99.96% efficient at 0.1 microns, so it captures mold spores along with the very fine particles mycotoxins travel on. Then the carbon adds a second layer: its pores adsorb musty mold gases (MVOCs) and help with mycotoxins. Fixing the moisture source always comes first; our basement mold guide has more on that.
Every 4000 is the same machine; only the filters change, based on the filtration you need. If you’re interested only in heavy VOCs, gases and odors, we recommend the Amaircare 4000 VOC Chem, which uses an estimated 30 lb carbon canister and NO HEPA. For salons doing keratin, Brazilian Blowout or other hair smoothing treatments that can release formaldehyde, the Amaircare 4000 Air Purifier for Hair Salons uses Formaldezorb, a special carbon blend designed for formaldehyde. And if your needs change later, you can convert your unit simply by switching to the filters for your new focus.
Amaircare rates the 4000 for 18,000 cubic feet at 1 air change per hour, which works out to about 2,250 sq ft with 8 ft ceilings. With heavy contaminants, more than one air change an hour is usually needed. Allergy and asthma clients often want 3–7, and heavy VOC or smoke areas may even call for 10 to 12. When VOCs are the main goal, size the unit at a medium setting, so the air passes through the carbon more slowly, and make sure it can clean the air faster than contaminants are coming in. For larger facilities, 2 or more units are often placed to complement each other. Every space is different, so email us your square footage and what you’re filtering, and we’ll help you size it.
Also available in 220 V and most plug types.
The 4000 VOC with HEPA uses one 16″ Annual Plus VOC Filter Kit and one 16″ HEPA filter. The 4000 VOC Chem, with its estimated 30 lb carbon canister, uses one 16″ Ultra VOC kit instead. Our recommended filter maintenance:
Because its filters can be custom designed for the job, the Amaircare 4000 VOC Chem with HEPA AirWash fits a wide range of air purification needs. You’ll often hear it called an air scrubber, air wash, Chem Airwash, heavy-duty air purifier or commercial air purifier. With HEPA for fine particles and carbon for VOCs, gases and odors, some common uses are:

There are 2 configurations for the 4000. Something to keep in mind: the machines are identical, and the filters vary based on the filtration needed.
With this in mind, if your usage changes over time, you can simply change your filter configuration to match your filtration needs.

Every Amaircare 4000 is the same all-steel machine, with the same motor, variable speed control and 6″ duct port intake, covering 18,000 ft³ (about 2,250 sq ft with 8 ft ceilings) at 1 air change per hour. What changes is the filter setup, matched to what you want the unit to do. Since the machines are identical, you can change the setup any time by switching filters.

Please note: the salon brochure covers the standard salon units. It doesn’t show the upgraded unit we offer for clients whose straightening treatments can create formaldehyde. That unit is our 4000 Hair Salon Purifier, made with an upgraded carbon for formaldehyde and other hard-to-get chemicals, which is why its price is slightly higher than the brochure’s.
Most clients buy one annual kit a year, chosen for what they want the unit to do. Your 4000 VOC with HEPA uses the 16″ ET Plus Annual VOC Filter Kit and the 16″ HEPA filter, highlighted in yellow below. Since every 4000 is the same machine, you can change the setup any time by switching filters. The kits under the divider give you the 4000 VOC Chem setup, for heavy chemicals and odors, or the 4000 for Hair Salons setup, for formaldehyde.
| Kit or Filter | What’s Inside | When to Change |
|---|---|---|
| 16″ ET Plus Annual VOC Filter Kit Your 4000 VOC with HEPA uses this kit |
1 washable 1/8″ foam prefilter, 1 granulated carbon canister (the 7 lb canister, with 1,550 g of carbon) and 1 O-ring gasket. The kit is also offered with a pleated VOC filter or Formaldezorb carbon. | Foam prefilter: check every 3 months, vacuum or hand wash as needed, replace once a year Carbon canister: estimated 1 year, depending on contamination levels, or sooner when there’s a noticeable increase in odors |
| 16″ Easy Twist HEPA Filter Your 4000 VOC with HEPA uses this filter |
1 pleated Easy Twist HEPA cartridge with 100 sq ft of media, sold separately | Check every 2 years, and replace when the outside of the media turns dark: about every 2 years in commercial use, 3–5 years in homes |
| To change your setup, you can also choose: | ||
| 16″ VOC Ultra 30 lb Filter Kit with standard carbon |
1 washable 1/8″ foam prefilter, 1 estimated 30 lb carbon canister (9,475 g of granulated carbon) and 1 O-ring gasket. The canister takes the HEPA’s place, for heavy VOCs, chemicals, gases and odors: the setup of our 4000 VOC Chem. Coconut and Multizorb carbons are offered too. | Foam prefilter: check every 3 months, vacuum or hand wash as needed, replace once a year Carbon canister: estimated 1 year, depending on contamination levels; because the canister is so large, many clients get longer out of it |
| 16″ VOC Ultra 30 lb Filter Kit with Formaldezorb carbon |
The same kit, its canister filled with Formaldezorb, a special carbon blend designed for formaldehyde and other toxic chemicals. It’s the setup of our 4000 for Hair Salons, and the one to move to if formaldehyde comes into the picture, for example when a salon adds Brazilian Blowout or keratin smoothing services. | Foam prefilter: wash or change it weekly in a salon, with a new one at least once a year Carbon canister: estimated 1 year, depending on contamination levels; replace it once it’s exhausted |

Note: Plain activated carbon has limited capacity for some reactive gases, such as ammonia and formaldehyde. For a chemically reactive gas, we may recommend an appropriate impregnated or specialty carbon instead, such as Formaldezorb, and there may be an extra charge for it.

Hi Barb,
Every time I'm working in my shop I think of you and the expertise and help you provided.
Before installation of the system you configured for me (my initial review below) my shop and our entire basement smelled of machine oil that emanated from my CNC lathe. After I installed the system you configured for me not only do I not smell machine oil or the VOCs being released from the acrylic as its temperature increases during the machining process. My shop and our basement no longer has that smell at all!
As you suggested, I leave the unit on 24x7 at a slow RPM to increase the soak time through the charcoal element.
And because our home's HVAC system draws some air from my shop I'm certain our whole home is more safe, too.
Thank you, Barb!
Paul
Thank you for the feedback, Paul. Glad we could help you. Have a good day, Barb
My application is within a small machine shop located within my home. I machine various types of acrylic plastics on a CNC lathe that emit fine dust and VOCs throughout the process; this "cloud" is within 12 inches of my face. I found Barb at US Air Purifiers to be hugely helpful in understanding my concern for the long-term negative effects to my health of breathing these airborne particles and chemical vapors. She asked excellent questions to land upon recommendation for this product especially configured for my situation. The feeling of having her subject matter expertise and recommendation was and remains amazing. The unit was very simple to setup. After positioning the unit behind and to the left of the lathe chuck, I tested the draft airflow with fine talc flicked from a small brush right where the acrylic rod is machined. I watched as the simulated "cloud" was pulled away from me and into the Americare. I am EXTREMELY happy with everything start to finish. Thank you, Barb!
every thing ok but how do you put toghether no manual drawings
Hi Peter, I'd be happy to walk you through the filters if you'd like to call sometime. There is one screw and to clips on the top. After removing the lid, you rotate the HEPA a 1/4 of a turn to the left to release it. Then you can lift it out. If there is a VOC blanket inside the HEPA, remove that. Then insert the VOC canister and replace the HEPA. To secure, turn the HEPA a 1/4 to the right (clockwise). Then secure the lid back on the unit. Let me know if you still have questions. Thank you, Barb
