We make comparisons to help you make good decisions.

If you love the outdoors, you know that mosquitoes can make it uncomfortable. Not only that, but mosquitoes also threaten our health. Nobody likes mosquitoes. We can all agree on that. So, what do you do?

Before you go outdoors, one thing you will always consider is a mosquito repellant. Unfortunately, not all types of mosquito repellants are as effective as others. Introducing Thermacell MR 300 and MR 450.

What is the difference between Thermacell MR 300 and MR 450? Well, we have prepared this detailed post comparison to help explain how these two differ when put side by side. Let’s get started.

Thermacell – An Overview

Thermacell has dealt with the challenge of mosquito repellants that are efficient in doing their job. The products we will discuss in this post do not make use of design. They allow everyone including hunters, campers, and other outdoor enthusiasts to go outdoors without worrying about the discomfort caused by mosquitoes.

But that’s not all. These two models will give you lasting protection, more than half a day of complete protection. The only thing that is required is a fuel cartridge coupled with repellant mats. You will therefore get a solution that does not rely on sprays, candles, or even cords. Sounds amazing, doesn’t it?

Thermacell mosquito repellents will create a protection zone of around 15 ft. That is adequate space to ensure that the nasty insects do not come anywhere close to you. You can even choose to use multiple repellants to increase the overall protection zone.

They are also powered by a fuel cartridge that works for around 12 hours. That allows them to emit a repellant that does not have any scent and repel any mosquitoes around you. The repellent mats will last around 4 hours before you need to replace them. You will also realize that they will change color whenever it is time to make a replacement.

So, how does it work? The system features three main components that make it possible for you to get a proper protection zone. It features a repellent mat, a cartridge, as well as a device that makes use of heat to activate the mosquito repellent.

There is a button in the housing that sparks the igniter. The igniter, in turn, will burn the butane and heat the pad. After a couple of minutes, the repellent will heat and the protection begins.

The protection will begin around 15 minutes after you start the repellent. The devices will work with all types of fuel refills or mats, including multi-insect repellents.

Now, the MR 300 and MR 450 are very similar to each other in certain aspects. Even so, we would like to look at how these two compare to each other in these aspects. But first, here is a table to give you an idea of how they differ.

Fuel Duration and performance

As mentioned before, both these models have a protection zone of around 15 ft. When you compare it to other types of mosquito repellants, it is very impressive. Additionally, these two will offer protection for around 12 hours. This is the time after which you will need to replace the fuel cartridges.

When you purchase either model, you will get a single fuel cartridge in the package. However, refills are available in packs of four.

The mats, which are heat activated, might differ in duration. While the original refills will only go for around 4 hours, other variants will go for around 12 hours. You can choose to have a certain earth-scented option, even though the duration is similar to the original.

Every purchase features 3 original mats, lasting 4 hours each. However, there are certain packs ranging from 3 to 75 mats in a pack.

When you compare Thermacell MR300 vs. MR450, you will realize that the MR450 model is quieter. That is thanks to the quieter ignition system that is featured in the MR450. If you are a hunter, this will be a helpful companion because it will not scare off the game each time you turn it on.

Finally, we loved that the MR450 features a rubber molding that gives it sturdiness like no other gadget. In case you drop your mosquito repellant, you can be sure that it will not break or stop working.

Technology and Design

Thermacell Technology and Design

These two models make use of a similar type of technology compared to other repellants. However, instead of using a very big device, this one is minimal and also portable, which is a great advantage for different reasons.

It is designed so that it can work while lying flat on any surface and not standing up. When you look at its design, it is similar to remote control or a flashlight. It features a wide area that is meant for the refill mats inserted under the vents. The handle also features the switch and the fuel cartridge.

When you compare these two, they have similar dimensions. However, the 450 is wider because it has an additional rubber case. This case is not only meant to keep it safe in case it drops, but also give you a better grip on the device.

You will also enjoy the one check coupled with a visual indicator that allows you to know if your protection zone is active or not.

The MR 300 has a wider range of choices regarding color. However, you only have two options for the MR 450 – gray and black.
