Product review (5 stars): Has made a big difference with my allergies thankfully.
My wife and I recently started to notice some issues with our central air unit and observed water leaking from the upper portion of our basement unit. After much research and troubleshooting we discovered that we had a humidifier unit as part of our whole AC system. Before this we actually didn't even know we had one. As you can imagine now that we've been in our house for over 4 years that our previous evaporator pad was beyond disgusting and even moldy.

Installing this evaporator pad was beyond easy and quick. You simply unscrew the cover, remove the old pad, place the new one in, and replace the cover. In a few seconds you're back to normal. I do have to say that i've noticed quite a difference in the operation of our whole unit, it runs quieter and is now using less energy to do so. With me suffering from severe allergies i've also noticed a great difference with some of my common allergy problems due to mold since i've changed this pad out. Now that I know I need such an item i've set myself a reminder in my phone to check the status of this pad every 6 months.
