Choosing the Right Evaporative Cooler Pad Material for the Weather

Choosing the best evaporative cooler pad can be difficult since it's effectiveness tends to change with the weather. Here is a guideline though that can help you find the right pad material, no matter the season.

Wood

When the weather is warm, you will want to use an evaporative cooler pad that is made from wood. Because wood absorbs a portion of the water, it cools some of the air that passes through its wood fibers. This causes the air coming out to be cooler in temperature. The aspen pad is one of the most common wood pads and is made from shaved aspen trees.

CELdek Media

This type of material is cellulose paper that comes in the form of honeycomb shaped blocks. CELdek media is a little more efficient than wood and provides a greater drop in temperature. This is because the material is thicker than the wood shavings are, so it absorbs and holds more water. This material is also more expensive though than wood is.

Plastic

Plastic cooler pads tend to be cheap, however not as effective in cooling the temperature as both wood and CELdek media. They tend to be thinner, so less water gets absorbed than the other 2 materials.

If you are looking for the best evaporative cooler pad, these three guidelines can help you to choose one.

Bathroom Ventilation Fans

In order to move moist air from a bathroom to the outside, bathroom ventilation fans are needed. Rated to vent a certain amount of cubic feet per minute (CFM), bathroom fans help to prevent the buildup of mold and mildew. They also keep moisture from damaging interior materials. Bathroom ventilation fans may provide fan-only use, or they may combine with a light to be multifunctional. Ventilation fans, as their name suggests, require a vent, typically 3 inches in diameter, to the outside.

Bathroom Fans

Bathroom ventilation fans may be either wall- or ceiling-mounted and most commonly consist of an inserted unit covered with a plain grille. Shapes range from circular to square and rectangular, and the CFM number indicates the amount of air the fan can effectively vent in a minute. The higher the number, the greater the fan's capacity. The CFM rating for residential bathroom ventilation fans usually ranges between 50 and 130.

Features

Most ventilation fans feature an enclosed condenser motor for quiet operation. Energy Star-qualified units are available, while those units that feature lights may come with deluxe fluorescent, energy-saving bulbs. A combination ventilation fan/heater provides warmth in the bathroom, perfect for when you step out of the bath or shower on cold days.
