Aspen (Wood Wool) Vs HoneyComb Air Cooler Cooling Pads

Summer is almost knocking at the door, and time to invest in a new cooler has arrived. But are you confused between honeycomb pads vs wood wool pads? Cooling pads are one of the most important components of any cooler, and they play a significant role in the cooling system. The cooling pads are the parts that transfer the colder water temperatures to the air around it. To learn which might be a better choice for your household, read on! 

What Are Aspen Cooling Pads?

What Are Aspen Cooling Pads?

Aspen or wood wool cooling pads, as you can guess from the name itself, are made of splinters from wood. The wood is first cut into the shape of logs and then arranged to mimic the form of grass. The cooling pads are usually made out of wood shavings (grass) and synthetic fibre. The pads almost look like dried hay and grass. The small splinters present in the aspen pads absorb the water being circulated to transform the hot and dry air into cool and humid air, thus cooling the room economically.  

Pros And Cons Of Aspen Cooling Pads

Wood wool or Aspen cooling pads provide a reasonable and satisfactory performance when it comes to cooling. The major plus of having an Aspen or wood wool cooling pad in your cooler is the economical factor, as the Aspen pads housed in your cooler are extremely cheap and easy on the pocket. However, a major problem that Aspen cooling pads face is that it needs high maintenance and needs to be cleaned regularly for the proper functioning of the machine. It can be used in extremely hot and dry climates, and are predominantly found in those areas where cheap coolers are in demand, but unfortunately, these pads demand more frequent and yearly replacements to keep the cooling pads up and running due to the very fragile nature of the pads. So, Aspen pads are not very durable and will require proper upkeep and maintenance. Read our guide on the how to clean an air cooler for more details. When compared to Honeycomb cooling pads, the Aspen or Wood Wool cooling pads are less effective in terms of performance. 

What Are HoneyComb Cooling Pads?

What Are HoneyComb Cooling Pads?

As you must have guessed by the very name itself, honeycomb cooling pads resemble the honeycombs made by bees. These types of cooling pads are made with a sort of special filter which is engineered from thick cellulose paper. Honeycomb cooling pads have moisture and water retention compartments, which transform the hot air to cool humid air very quickly by retaining the cool water for a longer time.

To make the honeycomb cooling pads more durable, these are treated specifically with chemicals so that they can resist deterioration and any problems for years. Usually, these honeycomb cooling pads are housed in desert air coolers and other high end branded coolers because of the proficiency of the pads to cool a larger surface area and provide better cooling than the aspen pads. This is why many of the best air coolers with blowers instead of fans have honeycomb pooling pads in them.

Pros And Cons Of HoneyComb Cooling Pads

Honeycomb cooling pads provide a much faster and better cooling over a larger surface area which is why they are usually housed in high-end coolers. They are also much better looking than the aspen pads and also very sustainable due to their prolonged longevity due to the use of chemicals to resist any deterioration on the pads. Therefore, they need less maintenance and don’t require regular upkeep. On the downside, they are more expensive than aspen cooling pads, and sometimes give out a bad odour during the initial runs of the machine, which can be irritating for some people.

A. Durability And Maintenance

The durability of a cooling pad is directly proportional to the maintenance of the cooling pad, which means that to increase productivity and longevity, all cooling pads, despite any claims of prolonged durability, must be maintained regularly. Aspen or wood wool cooler pads need to be regularly cleaned with water and vinegar and also require regular replacement at least once a year, while the honeycomb cooler pads are much more durable and are doused in chemicals that stop the disintegration of these pads. You can easily use honeycomb cooler pads without replacement for at least 3 years, which means that it requires much less maintenance than Aspen cooler pads. However, if you want to run your air cooler efficiently, we would recommend to clean your cooling pads regularly along with other air cooler parts.

B. Size And Thickness Of Cooling Pads

The size and thickness of the pads depend a lot on the type of cooler you are using. Obviously, in your air cooler, there is an optimal balance that needs to be struck between the size and thickness of the cooling pads for your machine to work properly. Honeycomb cooling pads are bigger and have 3 sides and therefore provide better cooling than the Aspen pads which are smaller in size and single-sided. 


Before investing in an air cooler, you must always read about the specifics of the cooling pads. While it is true Aspen pads might not provide cooling like the Honeycomb pads, Aspen pads are cheaper and can work better in hot and dry climates, which Honeycomb pads cannot because they only work well in humid climates. However, depending on your specifics you must decide on your air cooler so that you make the right choice.
