My Dri-Eaz F284 DefendAir Hepa 500 Air Scrubber Review (2021)

I’ve bought several negative air machine scrubbers in the past but the DefendAir Hepa 500 Negative Air Machine is the one I love this most.

I’ve used them in my mold remediation company and even my home. So I have a pretty good idea of what to look for in a air scrubber machine.

Key Features Of The Dri-Eaz F284 DefendAir HEPA 500

I found the following key features very useful

  • The unit is portable so you can move it to different locations in your home of office.
  • The unit has an adjustable or variable speed setting to increase or decrease the fan speed.
  • A power outlet is located on the top of the unit so you can connect other air scrubbers or devices.
  • Each unit is stackable- meaning if you have more than one unit and wanted to add another to increase the air exchange in the home, you can stack the units.
  • The Defendair Air Scrubber has a light that indicates when the HEPA filter needs to be changed.
  • The unit has two filters, the first is a pre-filter that captures larger particles, and the second is the HEPA filter that captures smaller particles like mold spores.

Weight of this Dri-EazAir Hepa Air Machine

When it comes to the weight of the unit, it is a little on the heavy side.

This is mainly because of the powerful motor in the unit. It weighs about forty pounds. Even though it may seem heavy, the handle is comfortable to grip and makes carrying the unit a little easier

Noise Level

The noise level of the air scrubber is not as  loud as you may think.  

The air scrubber has a variable speed setting dial that allows you to increase the fan speed which will create more noise or you can turn it down where it just sounds like a low humming sound.

So, depending on how high you have the unit running, that dictates the level of noise.

The noise can be the difference between a low hum when it’s set to low, or it can be a little bit loud if you have it turned on full blast.
