I think the KA50 does a great job at what its designed to do. Since I live in Arizona, it is very dry here. I end up using it all year round. In the summer its used to cool the house down and the winter to add humidity to the air since its on the extreme side of dry. When the manufacture states 350 sq ft, they mean it.

Since it does hold a lot of water it can be a pain to fill so I use a hose from my laundry sink. If you don't have one you can use a fish water siphon in reverse direction. There is a meter that tells you how much water is in the unit (Min - Max). It's just a float connected to a piece of plastic pushing the meter up. FYI if the unit is empty or very low, the float can tend to get stuck and end up overfilling the unit because it will still say Min when its full. A simple tap on the machine looses the float and you are good to go. Something to keep in mind but wouldn't deter me from buying.

The unit has 5 casters on it and move with little... Read more

I compared air conditioners vs air coolers for days before finally deciding upon the KuulAire PACKA50. Based on the features, cost and reviews, the KuulAire PACKA50 seemed to be the best choice. Honestly, a true air conditioner would provide a sure solution to a heat problem but in addition to costing around 50% more than air coolers, with true air conditioners, you must run an exhaust duct from the portable unit to the outside. The only option for doing that in the living room area of my home would require spending an additional $150 plus for a 'pet door' attachment to the sliding glass door.
The KuulAire PACKA50 arrived earlier than the estimated delivery date. Simply take it out of the box, add water and plug it in. The unit has a pretty strong fan and seemed to work well. Within a couple of days however, I knew that it would not be adequate for the problem I was trying to solve. I purchased the KuulAire PACKA50 to be used inside my indoor grow tent. The grow tent was... Read more

This unit does what I needed it to do. Provide humidity in my arid AZ bedroom. However, the filter has a glue that holds it together. When using the cooling aspect, once can clearly smell this glue and it is not horrible or bearable, but not pleasant either. The manual says this goes away in a week or so. It did not for mine, but I am sensitive to smells.

Unfortunately this means I don't use it because I don't want my room to smell like this. I am content at the moment with creating another filter from other evap coolers media like: Relion Humidifier Filter WF813, 2 Pack If this doesn't work then this thing is worth 2-3 stars max for me.

Other notes:
-This thing is loud. Put it in the farthest corner of your room so that the sound does not drown out TV and etc. Even the lowest things is as loud as a vornado... Read more
