The use of ductless fume hoods as well as filtered workstations has been giving benefits to laboratory staff all around the world for years, all while contributing to a more environmentally friendly and adaptable design for laboratories.
The use of filtered hoods has increased as a result of advancements in detecting technology, which has led to an increase in the total advantages enjoyed by laboratories in terms of cost reduction and reduced influence on the environment.
What does it mean to have a portable fume hood?
Since it filters the air before recirculating it in your laboratory, a mobile ductless fume hood is often referred to as a recirculating range hood. This is because the air is filtered before being recirculated. They are self-contained laboratory containers that function by drawing a constant flow of air over the work surface as well as drawing it through a filter to eliminate pollutants, particles, including chemical odors.
Portable or ductless fume hoods aren’t really linked to the heating, ventilation, and air conditioning system in your facility, in contrast to ducted fume hoods. They do not vent air outdoors like ducted hoods do; instead, they bring clean air back into your laboratory from where it came.

The following is a list of the top four advantages of ductless fume hoods:
Because it does not require installation, the cost of operating a ductless fume hood is significantly lower than the cost of operating a conventional laboratory fume hood. Each component has been checked for accuracy, and after it has been delivered, it will be ready to be put into use. The installation of a blower as well as ductwork through the building, in addition to the construction of the fume hood, is necessary for conventional hoods. Money and time are both required for all of this.
Due to the fact that it is not necessary to install it, the ductless fume hood has a significantly reduced cost of operation in comparison to the conventional laboratory fume hood. Each component has been checked for accuracy, and after it has been delivered, it will be ready to be put into use. The placement of a blower and ductwork through the building, in addition to the construction of the fume hood, is necessary for conventional hoods. Time and money are both required for this procedure.
Such units can be moved and made operational in a matter of minutes, but traditional laboratory containers could be out of service for several weeks. A ductless enclosure, with the exception of its power wire, does not have any external connections that would prevent it from being moved to a different position.
Before the unit can be moved, conventional laboratory hoods call for the assistance of a third party to move the exhaust ducting as well as other connections. Read more here.
Portable and ductless fume hoods only consume power when they are really being used, which means that they have the potential to be more energy efficient than traditional fume hoods, which often operate nonstop. Additionally, ducted fume hoods require the movement of air over greater distances, which requires additional energy.
When compared to the price of a ducted device, the initial investment for a fume hood that is portable and ductless is almost always going to be lower. The cost of connecting ducted units to the heating, ventilation, and air conditioning system of a building is an additional charge that must be paid on top of the initial purchase price.
Portable and ductless fume hoods typically have cheaper day-to-day operational costs than ducted fume hoods. This is because portable and ductless fume hoods have simpler fans and motors, which, in most cases, only operate when the machine is being used.
Easy to install
Most of the time, a ductless portable fume hood can be used soon after it has been delivered. The workers just roll the device to their workstation, plug it in, and insert the proper filter into it. In comparison, ducted fume hoods call for more intricate connections and frequently necessitate the acquisition of many licenses, permissions, and approvals before they can be put into use for the first time.
Building engineers may need to undergo training to guarantee that ducted fume hoods are properly maintained and operated, but portable or ductless fume hoods can be simply maintained by the personnel in the laboratory.
