Sourced an Alita AL15-A and an Ecoplus Pro20. Not sure which one to keep and which one to return. Not concerned that the Ecoplus 20 pushes more air. More concerned about quality and which will last longer.
I purchased them both and sent the Eco back. The Alita is great for low pressure uses and I don't think you would want to use them for Ozone, but they are very silent. I wanted to exchange the Alita 15 for a model with twice the output, but I purchased it on ebay and it would have cost too much to "exchange".
