What to consider when you are buying an evaporative cooler


A swamp cooler works as a cost-effective, healthy and eco-friendly air conditioner and also an alternative as an air cooler. So, while choosing the evaporative cooler, you have to consider some points that you have to while picking up:

The first thing is, you have to know the climate of your environment. As the swamp cooler works with the environment to make it cool, so the climate is important. Because all climates are not positive for all swamp coolers. Before getting one swamp cooler for your place check the climate is positive for the cooler or not.

You need space to keep the cooler because it needs it. If space is not correct, the cooler has to struggle to work with space to keep the environment cool. So, a whole lot of energy gets wasted. To know how much space will work for the swamp cooler, you have to know the CFM calculation. The formula is you have to multiply the square feet of the room with the ceiling height then divide the number by 2. The standard equation of a swamp cooler is 1800 CFM.

There are two types of swamp coolers – one is industrial, and the other one is residential. But the evaporative coolers only work in a large space, not the entire home. The residential coolers are the best option for single spaces. These types of swamp cooler are easy to move and operate as they come in lightweight. If you have a large space to keep cool, then you have to switch to the industrial swamp cooler. These coolers are huge and have remote control features.

You have to keep knowledge of the features that are must-have for a swamp cooler. The features are:

1.Cooler pads: the evaporative cooler pads are one of the important of evaporative cooler parts. You have to check the thickness of the pad. The thicker the pad is, the cooler your room will get.

2.Speed: a cooler with regulating speed is highly recommended. Some coolers come with variable speed, and speed can be controlled. Check out the cooler with less noise and speed cooling effect.

3.Control of the water level: a swamp cooler with water control level should be automatic. Because the automatic controller maintains the pre-set levels of water and there will be no chance of water leaking.

4.Dampeners: make sure there are shutoff dampeners that reduce the cooling loss. This dampener stays in the duct and controls the open and close operation when the fan works.

Pick the inverter evaporative cooler to save energy. This feature also works as a cost saver.

How Do The Best Swamp Cooler Pads Work?

A swamp cooler works excellently in dry weather by adding moisture and cooling the air. The swamp cooling pads are an important part of the cooler. The pads are fully responsible for cooling the environment and making it comfortable. The ways the cooling pads work is:

  • In the swamp cooler, the pads allow water to pass through.
  • The pump inside the cooler manage the water circulation through the pads.
  • When the water comes and passes through the pads, there is a fan that blows over the pads. This releases the water filled the air in the atmosphere.

  • The air evaporates the water and cools the environment.

The Best Type Of Swamp Cooler Pads:

Now, this part is very important as the cooler pads are essential ones. These pads keep the air cooler run properly. For a standard swamp cooler, there are types of cooler pads. Here are small brief about them:

Aspen Swamp Cooler Pad:

Let me tell the thing that the best swamp cooler pad type is aspen pad. This pad gives the best cooling capacity. You will find them in two different size – 1 inch and 2 inches. The thick one absorbs water most. Normally the aspen pad made of aspen fiber. This fiber is natural and for this the water-absorbent power is good. As the aspen pad holds water for a long time, they stay saturated and keeps the air cool. This pad needs to replace every year.

3.The cooler pump gets clogged as the fiber falls apart.

4.Needs a lot of maintenance.

Blue Synthetic Cooler Pads:

This blue cooler pad is spongy and made from synthetic material. Being synthetic the pads don’t get a sag or weaken. The pad lasts longer and no chance to get flake pad after use. But the thing is this pad have not that good capacity to absorb water like the aspen pad. This because of the material, so the pad gets dry soon, and the cool air gets hot. Additionally, the fiber absorbs the water mineral and creates a buildup that reduces airflow. You have to change or replace the pad every year.

The good things about synthetic cooler pad: 

1. Don’t get damaged so easily.                                                                            

2.Have no odor.                                                                                                                                     3.Fit for any cooler size.

The bad things:


1. Water absorbing power is not well.

2. The cooling gets less for the hard water.

3. This pad creates rust in the cooler.

Master Cool Swamp Cooler Pad:

If you want alternative pads, then you can go for this pad. This pad is made of honeycomb-shaped paper. The paper ensures high cooling ability. This pad comes in two sizes- 8 inch and 12 inches. The thick one absorbs water well. For the cooling ability, the swamp cooler owners are upgrading the cooler pads to master cooler pad. The best thing about this pad is you don’t need to replace every year.

The good things about master cooler pad:

1.The cooling capacity is just excellent.

2. Water absorption power is good.

3. No chance of getting deteriorate.

4. Gives service up to 3 to 5 years.

5.You will find them in 2 sizes – 8 inches and 12 inches.

Breezair Swamp Cooler Pad:

2.Don’t create buildup from hard water.

The bad things:

1. This pad is only made for breezair swamp cooler pad.

What Material Does The Best Swamp Cooler Pads Comes From?

While choosing the evaporative cooler pads, you have to pick the right pad with the right material that will keep your air cool. So, let’s check out the material:

  • Wood: For warm weather, wood made cooler pad is the best option because wood absorbs water well and makes the air cool. The aspen pad is the best example.
  • Cellulose:This type of pad comes from the cellulose paper material, and this paper comes in honeycomb block shape form. This material is better than wood because it ensures cold temperature. The cellulose pad is thick, for this, the water gets absorbed and stays in there for more time.
  • Plastic: If you want the cheapest pad, then go for the plastic cooler pad. But you will not get effective cool air like the other cooler pads. The pad is thin and cannot absorb water that much.

How To Clean Swamp Cooler Pads

You have to keep your swamp cooler clean especially the swamp cooler pads to have a cool air constantly in warm weather. When you are feeling the cooler is not working then you have to understand that your cooler pads need to be clean.

You may think that cleaning the pads is not so important. But you are wrong because a lot of water usage especially hard water makes the pad weak. In the hard water, there are kinds of minerals like iron, magnesium, calcium and dissolved rock that is super responsible for creating build ups that reduce the cool air. At a certain time, the pads stop working and your room temperature will get warm and smelly. By cleaning this build-up, you can improve the efficiency of the pads.
