Features to consider when choosing evaporative cooler
Some of the information you need to understand are the features listed and what they mean. This includes airflow performance, which will often influence the total cooling area. Evaporative coolers should also help save on power, so checking out power consumption may be a good idea before purchase. Below are a few of these features and what you need to know about them as you head into the market.
Airflow & Cooling area
Often airflow is measured in CFM an abbreviation of cubic feet per minute. Technically this means the speed at which air flows in or out of a particular gadget, in this case, the cooler. As such coolers with a higher CFM tend to perform better and as a result, can cover a larger area. Consequently, those with the highest CFMs tend to be geared to outdoor usage where there is a lot more space. A prime demonstration of this is seen in the Hessaire Products MC61M Mobile Evaporative Cooler which has a CFM of over 5000. Consequently, its cooling area spans about 1600 sq. ft.
Indoor gadgets don’t need as much airflow to work effectively. You can use a device with as low as 214 CFM such as Whirlpool WPEC12GW Evaporative Air Cooler without infringing on air quality. However, this is also dependent on the size of the room.
If you are buying one of these gadgets, the chances are that you also want to save on electricity costs. The process of cooling the air is entirely natural and therefore doesn’t need to use as much electricity as other air conditioning options.
The different machines come at various power usage capacities. This is sometimes indicated on the package with the most powerful coolers taking up the most power. Even different products from a single manufacturer can have different power consumption needs. The MC18M, MC37M, and MC61M all by Hessaire show you how much electricity consumption may vary.
Water tank capacity
Larger outdoor models tend to have larger tanks. Also, they often have a float valve that lets them use a continuous water supply from a tap somewhere in the house. They, of course, tend to expend more water and as such, are quicker to dry up.
Indoor coolers don’t need as much water, and you can have one with as little as 400ML capacity. If you are buying one for your patio, then about 10 gallons of water is what you should be aiming to buy.
Dimensions & Weight
Everything has to be proportional and so with a larger water tank comes a large body. In the body, there are, of course, corresponding size cooling pads and fans. In terms of power, bigger is generally better, but there are innovations in efficiency that help smaller models work just as well.
If you want to move it around once you have the cooler in your home, the more powerful bigger models will generally tend to be heavier. However, manufacturers are now countering that by including casters that might help you drag around the machine instead of carrying it.
Our most expensive listed product the Hessaire MC61M costs about $550 while our cheapest costs only $45. In between, there is a whole range of prices that you might find you can afford. If you plan and prepare a budget for the cooler that you want to buy the market prices will not surprise you. Overall purchasing one of these should still be cheaper than using your traditional AC.
