10 Best Dryer Booster Fans Of 2022

Among the different household equipment, dryers are on top of the list for my ‘life-saving’ equipment. They come in handy when I am doing that last-minute laundry, which should be dry the following day.

However, just like any other equipment, they too have their problems and maintenance needs. If you have visited this site and are reading this article, then it means that you are experiencing a problem with your dryer.

The specific problems I suspect you are experiencing include longer drying times or accumulation of lint in the dryer ducting. This can be quite frustrating, especially if you are a last-minute person like me. 

The solution to this problem is quite simple! Get a dryer booster fan, and because it might be hard to do this, I have prepared a guide with a review for the best dryer booster fans.

Why do I need a Dryer Booster Fan?

Having a clogged dryer vent is not a walk in the park. Clogged dryer vents trap air keeping clothes hot and moist such that if you remove them after a cycle, the clothes will still feel damp.

For me, clothes taking longer to dry is purely annoying (especially since I am a last-minute person). Sometimes, people will ask the question of how they can prevent this clogging.

Whenever there are clothes and dryers, lint is bound to appear somewhere in the figure. This leads to the unfortunate but truthful answer- that some things are not preventable. However, getting a dryer booster fan can help reduce the problem and its effects.

Have you ever moved and found that you cannot set up a dryer next to an external wall? Before I learned that the dryer booster fan would be of use, this is one nightmare that I always dreamed about.

When you find out that you cannot set up a dryer next to an external wall, the only viable solution usually entails installing longer dryer ducts. If you connect the dryer to ducts that are 25 feet or longer, it is advisable to get a dryer fan to ensure that the dryer continues to work speedily. The above are the main reasons why you should get a dryer booster fan. 

It would be unfair to leave you at getting a dryer booster fan without talking about how it works to solve your problems. The dryer booster fan helps in boosting airflow through the dryer duct.

A boost in the airflow reduces the amount of lint back up and significantly reduces the amount of time for drying clothes. There are two ways that you can switch your dryer booster fan- through a pressure switch or a current sensing relay.

How Do I Install My Dryer Booster Fan?

What stood out for most of the dryers reviewed above is their ease of installation. This tells us that installing your dryer booster fan is far from complicated.

Before I tell you how to install your booster fan, you must understand where it should be positioned. The fan has to 15 feet away from the outlet. It should be positioned at the end of the ducts to make it more comfortable during maintenance.

Installation involves cutting the existing duct. I have seen people use different duct materials and pipes, such as flexible vinyl and rigid PVC pipes. However, this almost always results in a broken-down system as these materials cannot handle the high temperatures from the dryers.

As such, you should use aluminum pipes. This is then followed by attaching the booster fan. Ensure that the booster fan at this point is in line. It is as simple as that unless the equipment requires some electrical work, such as the Tjernlund in-Line Fan Dryer Duct Booster 4″. However, for most of the dryer booster fans, no electrical work is needed.

Commonly Asked Questions When Selecting or After Purchase of a Dryer Booster Fan

We all agree that purchasing new equipment comes with a myriad of questions. Although the bulk of those questions has been addressed in the above section, this information is not adequate.

Additionally, there is some information that comes with the fans, but it is still inadequate. It might appear harsh to say that this information is inadequate. However, it comes from a personal experience.

When I purchased my first dryer booster fan, I used an essential lint bag to catch all the lint. Those who have attempted this know that it is a fire hazard. I was lucky enough that a maintenance guy stepped in before this situation turned fatal. 

This incident forms the basis of the first commonly asked question- can you use a simple basic lint bag to trap lint? Do I need a lint trap in the first place? The answer to the first question is NO.

However, some people argue that this basic lint bag will work well for collecting lint in short dryer ducts- without dryer booster fans. Using it with a dryer booster fan could easily lead to dislodging of the lint, causing the potential for a fire of the lint to come into contact with a hot fan. What is the solution? Ensure that the lint bag you install has ridges.

On the second question, you will need a lint trap! Lint is something that we cannot avoid where there are clothes and dryers involved. You need the lint trap more if the dryer booster is more than 15 feet from the central unit.

I bet that you wouldn’t like your drying room to have low air quality circulating within it, including the dampness of mold buildup. A lint trap helps take care of this in addition to increasing the durability of the HVAC system.
