Title: Short Lifespan
Review: The BestAir box states, "For best performance, change at least twice per season, maybe more depending on water conditions and frequency of use." In my case, this pad failed badly, decomposing and gathering algae/mildew within 3 months of heavy mid-winter use in a heat pump system that runs frequently. I've placed two photos of failed pad in the user photos section here. I think that when it was working properly, the paper panel increased humidification over the all metal panel, but it has a very short lifespan compared to the 1 year recommended change interval for the metal panel (see Aprilaire website). I would not recommend this pad for heat pump systems, since they run much more frequently than a gas/oil system. This pad may be a good upgrade for a fossil fuel-based system, but make sure to check and change it frequently.
