I put a shallow pan of cat litter behind my dehumidifier for 2 weeks this May. This is what happened

As the warmer months approach, many of us find ourselves battling the excess moisture that creeps into our homes. This May, I decided to tackle the humidity problem in my basement with an unconventional method: using cat litter. While dehumidifiers are a common solution, I was curious to see if a shallow pan of cat litter could enhance its effectiveness.

With a penchant for DIY home improvement hacks, I embarked on a two-week experiment to see if this simple addition could make a noticeable difference in the room's air quality. Armed with a dehumidifier and a shallow pan of cat litter, I was eager to find out if this combination could lead to a drier, more comfortable environment.

The idea of using cat litter as a moisture absorber isn't new, but its application in conjunction with a dehumidifier was something I hadn't tried before. Bentonite clay, a primary component in many cat litters, is known for its absorbent properties. I was curious if placing a pan of it behind my dehumidifier would enhance its efficiency and speed up the humidity reduction process.

Given the 400 square foot area of my basement, I needed a solution that wouldn't break the bank. A 10-pound bag of cat litter cost me around $10, making it a cost-effective experiment compared to other moisture-control options. My goal was to see if this simple addition could help the dehumidifier work more effectively without increasing energy costs.

To set up the experiment, I purchased an aluminum roasting pan and filled it with about 2 inches of cat litter. I placed the pan directly behind the dehumidifier, which was positioned in the center of the room to ensure optimal airflow.

Before starting, I measured the baseline humidity level in the room using a digital hygrometer, which read 65% relative humidity. This initial measurement would serve as a reference point to evaluate any changes throughout the experiment.

Within the first day, I didn't notice any dramatic changes in the room's humidity level. The hygrometer showed a slight decrease to 63%, but it was hard to attribute this solely to the cat litter setup.

However, I did observe that the air felt slightly less musty, which was a positive sign. The dehumidifier's water collection tank had slightly less water than usual, suggesting that the cat litter might be absorbing some moisture.

Over the two weeks, I noticed that the dehumidifier's water tank was filling up more slowly than usual. On average, the tank usually needed emptying every three days, but with the cat litter, it stretched to four days.

This indicated that the cat litter was indeed absorbing some of the moisture, reducing the burden on the dehumidifier. However, the difference wasn't as significant as I had initially hoped.

By the end of the first week, the room felt noticeably drier, and there was a marked reduction in the musty odor that typically plagued the basement.

The air quality felt fresher, and I no longer detected the damp smell that was once prominent. This change was confirmed by a drop in the humidity level to 60% by the end of the experiment.

One unexpected side effect was the increase in dust around the dehumidifier. The cat litter, being clay-based, generated some dust, which required more frequent cleaning.

Additionally, the dehumidifier seemed to operate more quietly. I surmised this was due to the reduced workload, as the cat litter absorbed some of the moisture.

The cost of the experiment was minimal, with the total expenditure being the price of the cat litter. However, convenience was a factor, as I had to stir the litter every few days to ensure maximum absorption.

Over the two weeks, the litter became saturated, and I had to replace it once, costing an additional $5. This was a manageable expense, considering the overall improvement in air quality.

The combination of the dehumidifier and cat litter did result in a drier environment. The humidity level decreased steadily, and the room felt more comfortable.

While the change wasn't drastic, the overall air quality improved, making the basement a more pleasant space to spend time in.

After removing the cat litter and allowing the dehumidifier to function on its own, I noticed a gradual return of the musty smell within a few days.

The humidity level also began to creep back up toward the original 65%, indicating that the cat litter had been contributing to moisture control.

According to experts, cat litter's moisture absorption properties are effective in small, enclosed spaces, thanks to the bentonite clay. However, its impact is limited in larger areas.

While the experiment showed some success, experts suggest that cat litter is best used as a supplemental measure rather than a primary solution for moisture control.

Based on my experience, I would consider using cat litter again, especially during particularly humid months. However, I might use a larger container or multiple pans to cover more area.

Additionally, exploring different types of litter, such as silica gel-based options, could potentially offer better moisture absorption without the dust issue.
