(Why don't we show the price?)

Retailers have the legal right to set their own prices, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's “minimum advertised price,” the manufacturer does not allow us to show you our price until you place the item in your cart, or in some cases, proceeding to the final checkout stage. Taking these steps allows Appliances Connection to show you our price consistent with our goal of always offering you the lowest possible prices on the widest selection of products. You are not required to purchase the product to see our lowest price, simply just remove it from your cart.

Follow Me:

Auto Restart:

Auto Swing:
You can set airflow to personal preference, or allow MRCOOL Oasis to automatically distribute air evenly throughout the space.

System Protection:
MRCOOL Oasis automatically detects when internal coolant levels drop too low. It will alert you to the problem before the compressor is damaged or air comfort degrades.

Low Ambient Cooling:
Need to keep a hot kitchen or computer room cool even in bad weather? Low ambient cooling will prevent heat exchanger frosting all winter long.

Cold Catalyst Filter:
The cold catalyst filter collects bacteria and other odor causing pollutants to purify the interior environment. It will leave indoor air cleaner and sweeter.

When you need air comfort as soon as possible, Turbo will help you get there quickly.

Louver Position Memory:
Set the louver to direct the air exactly where you want it to flow. MRCOOL Oasis will remember your preferences, and set the louver accordingly every time you turn it on.

Additional Features:

  • Low ambient cooling technology ensures effective operation even when the weather outside is cold and crisp.
  • Follow me operation enables the system to monitor the temperature where you are, not a thermostat on the other side of the house.
  • Louver position memory allows you to set the Mr Cool Oasis to your specifications the first time you use it and, if desired, never adjust the settings again.
  • Energy efficient performance ensures a Mr Cool Oasis operates both effectively and affordably. In many cases, replacing an outdated heat pump with Mr Cool Oasis will save money.
