Keeping your air clean, safe, and free from harmful airborne particulates is a top priority for business owners maintaining industrial or other large spaces. From the front office to the shop floor or warehouse (not to mention other gathering spaces like cafeterias, locker rooms, or auditoriums), indoor air quality matters.

Today’s customers and employees think about indoor air quality far more than they did just a few years ago thanks to the COVID-19 pandemic. Where a few years back people may have just hoped for the best, now your staff wants to know what you’re doing to keep them safe.

Commercial or industrial air purifiers are a proven strategy for improving indoor air quality, including in spaces where outdoor air exchange is impractical or impossible.

But finding the right solution—one that offers truly reliable and comprehensive coverage—can be a challenge. So we’ve rounded up 6 of the best industrial air purifiers available today. Below we’ll give you a quick overview of each system, including any unique features that set them apart from the rest.

1. AirBox Apex 2.0 Industrial Air Purifier

The AirBox Apex 2.0 series is a cutting-edge marvel in industrial air purification. Built from a high-strength, aircraft-grade aluminum alloy with a stainless steel enclosure, this American-made industrial air purifier is solidly built to exacting standards, and it shows.

The Apex 2.0 features integrated clean-room technology and relies on a certified and tested commercial HEPA filtration system to cleanse the air of airborne particulate matter down to 0.3 microns. In fact, AirBox’s systems are so well-built, they exceed the HEPA certification standard of >99.97% of particulates captured. AirBox pushes this above 99.99%.

At maximum wattage (which is minimal compared to other purifiers of its size), Apex 2.0 processes 1,500 cubic feet of air per minute (CFM), or 90,000 per hour. Apex also uses a three-stage filtration system:

• An optional activated carbon odor shield filter
• An antimicrobial filter
• A Certified HEPA filter

Mobile, stationary, or suspended: you choose the right application for your industrial space. Apex 2.0 can be installed in any of these three configurations.

AirBox also offers the most comprehensive warranty: five years, all-inclusive.

Obviously, we’re biased, but the facts don’t lie. Overall, AirBox Apex 2.0 is the top choice in industrial air purifiers thanks to its impeccable design, quality, and effectiveness.

2. Austin Air HealthMate Plus

Austin Air HealthMate Plus is another strong choice that relies on medical-grade HEPA filters for the final stage of filtration. Featuring a four-stage filtration system, the HealthMate Plus takes a slightly different approach:

• Stage 1: PERMAFILT pre-filter
• Stage 2: Medium particle filter
• Stage 3: Carbon blend filter
• Stage 4: HEPA filter

The HealthMate Plus is smaller than the Apex 2.0 and can effectively treat rooms up to just 1500 square feet. Its maximum airflow is 400 CFM (compared to Apex’s 1500).

Though the HealthMate Plus isn’t as powerful, it is more portable, featuring four caster wheels that allow it to be moved from room to room.

Its portability and comparative lack of power make the HealthMate Plus a better choice for smaller spaces, like offices or small lobbies or waiting rooms.

3. Enviroklenz UV-C

Enviroklenz UV-C is built with healthcare facilities in mind, though it suffers from some of the same capacity issues as the Austin Air HealthMate Plus. This semi-portable unit also has four caster wheels and takes a two-stage-plus-UV approach to air purification.

The stage 1 filter is an earth mineral pre-filter, and stage 2 is the medical-grade HEPA. Unique to this model is a continuously shining UV-C light covering the HEPA filter, potentially eradicating any living organisms that make it this far.

The Enviroklenz UV-C is unquestionably effective at what it does. But at just 250 CFU covering 1,000 square feet, it doesn’t offer the widespread protection that most industrial spaces require.

4. Aprilaire 5000

The Aprilaire 5000 is a durable, long-lasting air purifier with a bit more coverage than the previous two entries at 3,750 square feet and a max CFM of 2,000. This industrial air purifier is designed to be installed alongside an HVAC system rather than visibly present in a space.

The big drawback here is that the Aprilaire 5000 doesn’t use a HEPA filter. It uses both electrostatic technology and a microfiber filter, which should filter out 98% of particles. But that’s a significant gap from what HEPA filters can do.

Also, despite claims of impressive durability, Aprilaire offers just a two-year limited warranty. Most others offer more comprehensive five-year warranties.

5. Blueair Blue Pure 211+

The Blueair Blue Pure 211 is not the most impressive industrial air purifier on this list. But it is the most affordable. If you’re on a tight budget and the spaces you need to protect are small, the Blue Pure 211 is worth a look.

This air purifier relies on what the brand calls HEPASilent dual filtration, which combines a HEPA filter with washable fabric pre-filters and some other noise-dampening mechanisms. As a result, you’ll get that same 99.97% reduction in airborne particles that other HEPA filters provide.

The catch is that you’ll get that protection in rooms up to just 540 square feet. The Blueair Blue Pure 211 may be a good fit for individual conference rooms, small lobbies, and the like—but nothing larger. Washing the fabric pre-filters would be an added time and maintenance cost.

6. Coway Airmega 300S

The final purifier on our list covers over 1250 square feet with true HEPA-grade filtration, making it more appropriate for mid-sized spaces than some on this list. This type of HEPA filtration comes with a 1-year life expectancy of effectiveness. The Airmega 300S includes numerous settings, including five fan speeds and several time settings (so the machine will automatically stop running after a set number of hours).

Coway offers a mobile app for remote control, and the Airmega 300S is compatible with smart systems such as Amazon Alexa.
