The Best Air Scrubbers At a Glance

1. Abatement Technologies HEPA-AIRE H2KM Negative Air Machine

We consider the H2KM to be the best air scrubber for contractors in need of 2,000 CFM but not willing to pay premium prices. It's under $1,200 and delivers the same CFM output as units that cost 2-3x more. 

We really like Abatement Technologies as a manufacturer because the company individually tests every HEPA filter at the full 2,000 CFM airflow setting. This means you can rest assured the filter in your actual unit is certified at its rated capacity. Not just sampled from a production batch.

This is a solid unit if you’re worried about daily job-site abuse. It has a 20-gauge galvanized steel cabinet with water-tight pop-rivet construction. The 26-inch width fits effortlessly through doorways without having to remove the frame.

You have tool-free access to prefilters between jobs with a cam-latch swing-out door, too. The visual change-filter lamp takes all the guesswork out of maintenance scheduling, too. 

The H2KM runs on standard 120V/15A power. You don’t have to worry about plugging it in at any residential or commercial job site. It’s ready for the work, no matter where the work may be.

You can choose from two speed settings: 2,000 CFM and 1,300 CFM. This lets you match airflow to the size of the containment space. It only generates 70 dBA on high speed, too. It’s quieter than most other units in its weight class.

Three-stage filtration is standard: polypad, 2" pleated pre-filter, and 6" deep HEPA. However, you can upgrade to an optional 12" deep HEPA and carbon pre-filter for longer jobs or odor control.

2. Abatement Technologies HEPA-AIRE PAS2400 Air Scrubber

The PAS2400 is the most expensive option on this list, but you get what you pay for. It’s the best air scrubber for any contractor or business not willing to settle for poor build quality or features.

The 20-gauge stainless steel cabinet (not galvanized or polyethylene like most competitors) is as durable as it gets, so it’ll stand the test of time even when you put it through the wringer at job sites. 

It also has a zero-bypass design that prevents any air from slipping around the HEPA filter. It also has the highest CFM output here at 2,100 on the high-speed setting. 

One of the complaints contractors have with moving bigger, heavier air scrubbers like this one (it weighs 170lbs, after all) is moving it up stairs. The stair-climber function on this unit was added specifically to address that frustration. It also has a built-in dolly, and you can detach the upper pre-filter module so one person can separately carry it into tight work areas.

There’s a built-in hour meter that tracks cumulative run time so all your preventative maintenance is scheduled based on cumulative run time rather than estimates. The PAS2400 also features integrated pre-filter and HEPA indicator lamps. This tells you exactly which filter stage you need to swap out. You don’t need tools to access pre-filters, either, thanks to the hinged access panels.

This unit pulls strong negative pressure even through longer duct runs with max static lift of 5.5 inches. The unit itself takes up less space on the floor because of its upright configuration, too.

3. Abatement Technologies PRED-750 Air Scrubber

This is one of the most unique air scrubbers we’ll highlight today. It’s only 35 lbs with a built-in lift handle, so essentially any worker can handle it on their own. Carrying it up stairs, placing it on tables, it’s super lightweight. 

You can stack three high for storage and transport. Then, you can get to the job site and daisy-chain up to five units on a single 120V/15A circuit through the onboard GFCI receptacles. This is possible because the unit only pulls 1.9 amps. In other words, five PRED-750 units running simultaneously pull less than 10 amps total. 

Yet, you’re able to cover up to 37,500 cubic feet at 6 air changes per hour. A single unit delivers 6 ACH in spaces up to 7,500 cubic feet. You get fine control over airflow with variable speed from 200-750 CFM. 

The polyethylene cabinet is backed by a lifetime warranty. Three-stage filtration comes standard (1" coarse pre-filter, 2" pleated pre-filter, HEPA). But there’s an optional carbon filter swap for the pleated pre-filter if you’re worried about odor control. The hinged pre-filter door and control-panel filter-change indicator really simplify maintenance as well. 

4. Aerospace America 9150 Aeroclean 500 Variable Speed Air Scrubber

This smaller-scale air scrubber is ideal for jobs that don’t need a 2,000 CFM machine, and when noise complaints are a real concern. The variable-speed motor dials airflow between 100 CFM and 575 CFM. 

The entire unit draws only 2.1 amps at 115V. So, you can share circuits with other equipment and not have to stress about tripping breakers. That’s important in a lot of older buildings. 

It’s crafted from an aircraft-grade aluminum body, and it weighs just 44 lbs. It has two top handles so a single tech can move it on their own without help. 

There’s an 8-inch flex duct exhaust that supports negative pressure for containment work. The deep 12x12x12 HEPA cube filter holds particulate loading well relative to its size, and three-stage filtration (pre-filter, secondary, HEPA) protects the final stage from premature clogging. 

It may not be the most robust unit on the list, but it’s the best air scrubber for occupied homes, schools, offices, and healthcare spaces where keeping noise low during business hours is the top priority - aside from cleaning the air effectively, of course!

5. Airgle AG300 Air Purifier

We saved the last pick for something unlike the rest of the air scrubbers on this list - because it’s technically not an air scrubber. Yet, it’s one of our best-sellers here at US Cleaning Tools.

The Airgle AG300 is a desktop air purifier with cHEPA media rated at 99.999% efficiency down to 0.3 microns. It’s technically two orders of magnitude finer than a standard air scrubber. You also get germicidal treatment through the Titanium Pro UV-C module (254 nm wavelength). It’s Airgle's patented photocatalytic oxidation design.

The FDA actually cleared this unit as a Class II medical ultraviolet air purifier under 510(k) K232645 for destroying indoor airborne aerosols (including bacteria and viruses).

You can fit it on a desk, shelf, or nightstand at 14.3 lbs and under a foot wide. It has five fan speeds, connects to an app via iOS and Android, and only produces 32dBA of noise on the low setting. It works well in consultation rooms, private offices, or any small space where air quality is a huge priority. 

It can cover sq ft at 2.5 ACH or 144 sq ft at 5 ACH with an 8-foot ceiling. It has a 5-year warranty (residential) or a 2-year warranty (commercial). It’s also CARB certified and ETL listed. 

Which Air Scrubber is Best For YOU?

We’d love to talk with you one-on-one about which is the best air scrubber for your needs. All five of these units above are great. It just comes down to matching with your application. Here are some things to consider. 

Comparing Filtration

Every unit on this list filters to at least 99.97% at 0.3 microns (true HEPA). That’s the baseline for professional remediation and abatement work. Each unit also has its own pre-filter setups as well to protect that HEPA filter from working harder than it needs to.

But there are subtle nuances you need to know about in choosing the best air scrubber. For example, the Abatement individually tests each HEPA filter in the H2KM at rated airflow and certifies the specific unit. On the other hand, the PAS2400's zero-bypass cabinet adds another layer of protection as no air can skip the filter.

The AG300 operates at a different level - and is honestly a different type of device. You get cHEPA at 99.999% down to 0.003 microns, plus UV-C germicidal treatment. But it’s just not meant for containment or negative pressure with only 100 CFM.

CFM Ratings

CFM determines how quickly the unit cycles air through the space. The sizing formula is pretty simple: (room volume in cubic feet x desired air changes per hour) / 60 = required CFM. IICRC standards call for a minimum of 4 ACH in containment zones, with 6 ACH being preferred. 

The PAS2400 is the strongest on this list at 2,100 CFM. The H2KM reaches 2,000 CFM. But that’s not what every application needs. That’s why we highlighted a few models that range from 750 CFM to 500 CFM to 100 CFM.

You don’t have to worry about finding the best commercial air scrubber. Let our customer service team know what you tend to work with and we’ll help you find the right fit. 

Footprint and Portability

Where you’re going to work doesn’t just dictate CFM requirements, but also how big a unit you need. The AG300 sits on a nightstand at 14.3 lbs. The PRED-750 (35 lbs) and Aeroclean 500 (44 lbs) are both easy for one person to carry. On the other hand, the H2KM is a two-person lift at 124 lbs. The PAS2400 at 170 lbs.

Frequently Asked Questions

Do the air scrubbers really work?

Yes. They’re mandated on job sites for a reason. They capture 99.97% of particles at 0.3 microns. That includes dust, mold spores, lead particles, asbestos fibers, and other hazardous contaminants.

What is the best CFM for an air scrubber?

It depends on the size of the space and the required air changes per hour. IICRC recommends a minimum of 6 ACH for containment work (mold, asbestos, lead). You need to know the cubic feet of your space, then multiply by 6 and divide by 60. For example, a 10x12 room with 8-foot ceilings needs just 96 CFM (960 cubic feet). A 2,000 sq ft open commercial space with 10-foot ceilings needs 2,000 CFM. Keep it easy and get a recommendation from our team.

Which is better, an air purifier or an air scrubber?

Depends on the need, as they serve different purposes. Air purifiers just clean the air. They’re great for what they do. But an air scrubber is used for containment work: it creates negative pressure, handles high particulate loads, and exhausts filtered air through ductwork.

Is it safe to be in a room with an air scrubber?

Generally yes. Air scrubbers filter contaminated air without emitting harmful byproducts. But if the contaminated air isn’t safe for you to breathe, then you shouldn’t be in the space without PPE.
