Top Pick: Best HEPA Air Scrubber for Mold Remediation

Dri-Eaz F284 Defend Air HEPA 500 Negative Air Machine

Best Air Scrubber/Negative Air Machine - F284

The Dri-Eaz F284 Air Scrubber/Negative Air Machine HEPA 500 (that’s a mouthful) is a venerable competitor in the Air Scrubber space. Known for being a reliable workhorse, the only downside of the F284 is the premium price tag that comes with it. Make no mistake, the price tag is absolutely justified. We consider this to be a tie for best air scrubber. If the F284 is within your budget, buy it.

Some manufacturers use a numbering system that defines the maximum CFM of a negative air machine. Dri-Eaz isn’t one of them. The F284 is capable of a staggering 1,500 CFM. That’s triple the CFM of the BlueDri Air Shield 550. And, the F284 Negative Air Machine/Air Scrubber has more going for it than merely a high CFM rating.

Standout features include an onboard GFCI protected outlet allowing other equipment to be plugged into the F284. The power cord for the unit itself is 25 feet. And, of course, as the name would suggest the F284 takes a HEPA filter making it the right tool for the job for dealing with mold, lead paint, VOCs and more. It can also use an activated carbon filter for smoke and other odor removal work.

So, why wasn’t this the all around winner? The steep price point, while an exceptional deal considering the capabilities the F284 offers, may be out of range for some buyers.

Top Pick: Portable Air Scrubber for Smoke & Odor Removal

XPOWER X-2580 4-Stage Mini Air Scrubber HEPA + Carbon Filter

Best Commercial Air Scrubber for Smoke/Odors

As it’s longer name confirms, this potent air scrubber for smoke and odor removal has a 4-stage filtration system that includes both a HEPA filter and a carbon filter.

For smoke removal a carbon filter is a must. Being able to run the filter array the X-2580 allows is just one reason why it’s among our best air scrubbers to buy. This air scrubber is an excellent choice whether for smoke, odor, VOC and of course mold remediation. The X-2580 packs a lot of punch into its highly portable, compact ABS enclosure.

Weighing in at less than 24 pounds, we didn’t expect this unit to be big on moving air, but we were wrong. It’s 1/2 HP motor is rated for 550 CFM. And, it has a 5 speed motor which is a welcome feature for not only controlling air flow but noise, too.

How many of these air scrubbers would you need? A single X-2580 is effective for smoke or any other contaminant in a 1,500 square foot area. If in addition to harmful airborne contaminants you’re also looking for activated carbon filtration, put the X-2580 on your list.

Can the X-2580 also work on mold remediation sites? As we mentioned earlier, it can, but for those jobs we still recommend the higher performing, more flexible and powerful X-4700AM. Speaking of the X-4700, please note that if you need a more featured unit, XPOWER’s X-4700AM will accept a carbon filter.

Choosing the Right Commercial Air Scrubber

When selecting an air scrubber there are a few factors that should always be considered, including:

  • Airflow Rating – CFM, or cubic feet per minute, is used to express how much air an air scrubber can move. Be sure the unit you pick has a CFM rating that is suitable for the jobs it will be used for. Not sure how many air scrubbers you need for a job? Check out our air scrubber calculations.
  • Air Speeds – A great feature that makes a unit more versatile is a blower with variable speed settings. Not only does fan speed effect how much air is being purified, it also determines the level of ambient noise where the unit is placed.
  • Filtration – At the end of the day, filtration is what an air scrubber does. Pick a unit that can filter out the particulates you need to remove while reliably dealing with the strain the amount of airflow moving through it demands. Most units have HEPA rated filters. Some also have pre-filters and optional carbon filters. Pre-filters remove larger particulates, saving the HEPA filter for the smallest ones. Carbon filters remove VOCs and odor smells.
  • Portability – Today, most air scrubbers are considered to be of the PAS variety, which stands for portable air scrubber. Take note of the form factor, weight, number and placement of wheels, and if the scrubber has one or more handles to make moving it around easier.
  • Price – Quality usually comes at a price. While you cannot compromise on quality, you can right-size the air scrubbers you purchase for the type of work they’ll be used for. Buying units with inferior specs will introduce increased running time or the inability to perform the required work. Purchasing those with specs that far outpace the requirements of the work they’ll be used for is simply wasting money.
  • Quality – Always go with a tried-and-true brand which has a track record of manufacturing high-quality products. Knowing the type of work that you’ll require from a unit, make sure it’s up to the task.
