Why Trust Us

One of my main jobs as a content writer, for BYB and past clients in the outdoors and gardening spaces, is to track down the best products for our audience on any given subject. This includes picking the best items, reading reviews, studying ratings, and comparing each one against the others. Sometimes it’s basic, like finding the best gardening tools, other times it’s a bit more complex of a process, like choosing the best organic fertilizers, or the best two-stage snowblower. With so many great products available in some commercial niches, finding the actual best products is quite a challenge and requires a great deal of time and patience.

I’ve spent a great deal of time researching, learning, and educating our audience about evaporative cooling systems like swamp coolers. Part of that learning curve included swamp cooler pads. Regularly changing your swamp cooler pads is crucial when using evaporative cooling systems. Otherwise, you may end up propagating harmful mold and bacteria.

Best All-Around

Aspen Snow-Cool Cooler Pad
    The Aspen Snow-Cool Cooler Pad is one of the most preferred swamp cooler pads around, and for good reason. Have a look for yourself!



What We Like: The Aspen Snow-Cool Cooler Pad is one of the most trusted on the market. It is also marketed as “the coolest cooler pad.”

This popular and high-end swamp cooler pad is a stout one. Measuring 29 x 29 inches, and coming with five individual pads per package, the pads are preferred by many swamp cooler owners. The pads consist of an open cellular structure and signature Grid-Flo biodegradable stitching that absorbs more water than other pads. They have more evaporative wicking per square inch than most pads as well, which helps reduce water flow and pump issues within your evaporative cooling system.

Who Should Buy It: For those who want to invest in the tried and true, look no further than the Aspen Snow-Cool Cooler pad.

Runner-Up Best All-Around

DuraCool Evaporative Cooler Pad
    DuraCool's Evaporative Cooler Pad is another excellent solution for the average swamp cooling system, with a high efficiency foamed polyester design.



What We Like: The pads are much stronger than paper ones, consisting of foam and polyester. They can also be trimmed down to fit a wide variety of swamp coolers and evaporative systems.

The DuraCool Evaporative Cooler Pad is a step up from high-quality paper pads in terms of strength and durability. These long-lasting pads are made with foamed polyester and make excellent replacements for most swamp coolers and evaporative cooling systems that require a semi-large pad. That said, they also work with systems that need smaller pads (all you have to do is cut them down to size). The pads are designed for high efficiency.

Who Should Buy It: If you are looking for an efficient alternative to paper pads that need replacing constantly, these pads from DuraCool may be your best bet. They fit most swamp coolers and last longer than most.

Best for Honeywell Systems

Honeywell HC26A1008 Replacement Pad (for HE260 and HE360 models)
    The HC26A1008 is one of Honeywell's most popular evaporative cooling system replacement pads.



What We Like: These replacement pads from Honeywell are the official pads that should be used with the HE260 and HE360 systems.

Honeywell is one of the top evaporative cooler and humidifier manufacturers, which is why we think it’s necessary to include one of their best-selling evaporative cooler replacement pads. The HC26A1008 Replacement Pads from Honeywell fit the HE260 and HE360 systems. They’re stronger than most, long-lasting, and feature a thick layered honeycomb-like structure. The design promoted higher water flow and superior cooling. Be sure that the pad fits your Honeywell system, as they are not universal pads.

What Are Swamp Cooler Pads Made Of?

There is no one type of material that all swamp cooler pads are made of. Take the pads listed above, for example – one consists of aspen fibers, one of foamed polyester, and other evaporative-friendly materials. The range of materials used in common swamp cooler pads is wide; including paper, plastic, foam, rubber, and more. Make sure you know exactly what your replacement pads are made of before buying, especially if they are not the same as the original pads.

What Is the Best Type of Swamp Cooler Pads?

The answer to this question is one of personal preference. Or rather, it depends on the sort of swamp cooler or evaporative cooling system that is installed in your home. If you have a brand-name cooler, such as Lennox or Portacool, the best pad is the one designed specifically for your unit. Otherwise, you may need to shop around a bit until you find the one that works best with your system.

Can You Cut Swamp Cooler Pads Yourself?

The only time that you should cut swamp cooler pads yourself is when your entire swamp cooler is DIY. But even then, it may work out better to actually purchase the most suitable pad rather than cut one yourself. In most cases, if the pad is too large, all you need to do is fold it back around the edges before replacing the cover. Only if you have the proper tools (sharp scissors or razor knife), and safety gear (a steady hand and cut-proof gloves) should you consider trimming a swamp cooler pad.

How We Picked

Finding the best swamp cooler pads wasn’t as tricky as some products tend to be. The reason being that there is a terrible shortage of swamp cooler pads that stand apart from the general run-of-the-mill pads. Rest assured, the pads listed above were well-researched and thoroughly vetted before appearing on our list. We looked at the quality of materials and craftsmanship, guarantees, shape, size, and more before making our selections, as well as vigorously comparing each item with similar products. The five swamp cooler pads that made our list were the most effective, longest-lasting, and best rated.

Which Swamp Cooler Pads Are Best for You?

Choosing the best swamp cooler pads doesn’t have to be hard work. In fact, it’s a pretty simple task. Either your cooling system requires a specific type, or it doesn’t. If it doesn’t require a special pad, picking the very best one often comes down to the one that is shaped correctly. Remember, never try cutting a cooler pad that you purchase, even if it doesn’t fit perfectly. Rather, fold the edges back and place the cover back on.

All things considered, our top pick for the best cooler pads to invest in is the Aspen Snow-Cool Cooler Pad. It not only reduces issues with your swamp cooler, but its open cellular structure absorbs more water and creates cooler and fresher air. It’s also large enough for most medium to big swamp coolers. But those with Honeywell, Kuul Comfort, or Lennox Healthy Climate pads should stick with the recommended pads listed above.
