Lasko Box Fan Review: Find The Perfect Fan For Your Needs

A lot of my friends have been asking me about box fans and some have read Lasko box fan reviews and are tempted by what they have seen, but aren’t sure if they’re powerful enough.

Lasko is a popular brand that makes many different types of fans and other air-related products. They have a wide selection of box fans, which we have reviewed here.

Why has the Lasko brand become so popular when it comes to box fans? And, do they make the right type of fan for you? We explore more here.

Lasko: Presenting the Brand

Presenting Lasko Box Fans

Lasko has a huge range of fans and this includes their line of box fans. In order to fulfill the needs of multiple customers, they’ve created box fans to suit multiple homes and environments.

What these fans promise is a portable and affordable option for use in the home, which is slightly different from what is required in a desk fan or tower fan. They are simple to set up and use and relatively compact.

Lasko box fans are available mainly in a 20-inch size and each of the products in the range is pretty similar, when it comes to design. These fans can save you a lot of space and are a great choice for those who wish to extract things from a room and keep the airflow high.

Though they’re a little different from window fans, they can do a similar job if placed near a window. This means that smells, smoke, and stale air can be moved out and fresh air brought into a room.

Before buying from the Lasko box fan range, consider whether box fans are the right choice for you. They’re compact and usually very portable, as well as good for shifting air, but they’re not the quietest types of fans.

Think about whether the fan’s white noise will be welcome or something you want to avoid and also consider whether the size of the Lasko box fan is going to be big enough to give the power you need.

Features and Benefits

The following features and benefits are common to the Lasko fan range and can help you decide whether they’re suitable for you.

Fans create a bit of white noise and this can sometimes be seen as a benefit and may even help you fall asleep. Even when it isn’t hot, some people use white noise videos, such as the one below, to aid their sleep and relaxation. Lasko’s guide to choosing a fan touches on this noise issue, too.

The price is another big selling point of Lasko box fans. Box fans, in general, aren’t the most expensive type of fan on the market. But there is a bit of variation when it comes to Lasko’s box fan prices, depending on the features, and you might pay more for a weatherproof option, for instance. However, most are pretty affordable.

Most of the fans in the Lasko range have a setting for three different speeds, to allow you to choose the power level you need. This will also have an impact on the airflow and noise created by the fan.

Box fans are relatively efficient, too. The Lasko brand says that their products with “Save-Smart” cost under $0.02 per hour to run and, in this study by creditcards.com, it was shown that some box fans can even cost less than one cent per hour to run.

Portability is another vital feature. As well as being lightweight, all of the box fans in the Lasko range have a carry handle, meaning getting them from room to room is easy. This can make them far more convenient than tower fans, for example.

On third position in this list of Lasko box fan review is Lasko Cool Colors 20 .

The first one is its noise production which might be a deal breaker for most customers especially the ones that are light sleepers. Another thing that might create some problems for customers is its vibration at high speed settings.

  1. Great heater quiet and effcetive. This is a great heater! We use it to heat the living area of our RV. The living area is approximately 26 x 10 with normal height ceilings. We’ve tried a few different compact room heaters, but they were too small to heat the area and also way too noisy. We’ve had the heater about 4 months now. Since we are staying in cooler climates, we’ve used it almost every night (overnight).The best features about this heater are:- It’s QUIET!!!Really!! We have tried many heaters in our RV and house over the years and they tend to be so noisy. The model we tried before purchasing the Lasko was so noisy we had to crank the tv volume up to hear over it. This Lasko seems to be about as quiet as a fan could be.- It has an automatic thermostat you can set.This model has a high/low and auto setting. The high/low settings are not thermostat controlled. You simply choose hotter or less hot air. The auto setting allows you to set the thermostat to the temperature you desire. It seems reasonably accurate . That is, the temperature it displays is within 3-4 degrees of the other thermometers I have around the room. Once you set the thermostat, the heater cycles on/off, just like you would expect. This is a great way to keep the room at your target temperature. We use this mode every night.- It oscillates.This sounds like a silly feature to list, but it makes a big difference in heating up a room. The previous heaters we’ve had did not oscillate. Therefore, the area directly in front of the heater was warmed, but the rest of the room was not. The oscillation really helps get the heat moved around the room so that you are not creating hot and cold spots. We always turn on the oscillation to heat the room. I am sold on that feature and would not buy another heater in the future unless it oscillated.- It has a remote control.The only thing that would make it better is if you could see the settings on the remote instead of having to look at the top of the heater. But, if they did that, the cost would go up. So, I’m happy with this remote given the price of the unit.There are a couple of negatives about this heater:- To me, it is annoying that it beeps for every setting you change. This may be a problem if you plan to use it in your bedroom and change settings while someone is asleep. The beeping is really apparent when you want to change the thermostat. When you unplug the heater, it resets itself to 75 degrees. So, if you then want to set it to 60 degrees, you are going to hear 15 LOUD beeps. Turn it on beep. Choose oscillate beep. Change to auto setting beep. Decide to up the temperature by 3 degrees during the night beep, beep, beep and your partner is now awake! You get the idea. I assume Lasko designed the beep so that you would know you changed something while clicking the remote control. But, it’s so loud they should either make it softer or give you an option to turn it off.- There is no fan only setting.It seems like most heaters I’ve purchased in the past have a fan only setting. I’m not sure why this one does not. Since you have the big unit sitting there in your room, it would be nice if it could be used to circulate air during the day when it’s warmer, and then heat at night once the temps have dropped. Since we are using this heater in our RV, it’s more noticeable to me since we need to have space for the both the heater and a fan. Oh well.Overall, we love this heater and would buy it again.I rate it at 4.5 stars.(PS we bought it at a local store, not via Amazon, so I can’t comment on shipping).UPDATE 1/18/2010: We’ve had this heater about 1 year now and it’s still going strong. One thing I’ve noticed is that it will build up lint (Ummm ok, cat dog fur ). I wish there was a filter we could access and clean more directly. Oh well, other than that this heater is still doing great.
