Cfm Prem-I-Air SUMOWINTER Portable Air Conditioner Recommendations

For cooling larger areas up to 300 sq ft, the Sumo-J does what other smaller spot coolers don't - it actually works! Remember, evaporative cooling is dependent on the hot dry environment and typical smaller sized spot coolers just cant do the job on areas over 150 sq ft. Be smart and make your first purchase your last - its always a good idea to buy more cooling power than you think you need.
