Question: How do you open the top to clean?
Document: I purchased this airpot to replace my old one after the lever handle broke (probably from too much use - we drink a lot of coffee!). I chose the pump-top dispenser to avoid a similar problem in the future. The pot arrived quickly, was carefully packed and came with easy-to-understand use instructions. It is easy to use, easy to fill, easy to carry and easy to clean. It keeps a full pot of coffee hot all day and half the night.
The Zojirushi Air Pot kept our coffee hot for several hours. It was easy to use and easy to clean.
Running a B&B requires us to always be on top of our game...and this pot helps deliver! Keeps beverages and water hot so our guest is always satisfied when they need a cup of hot-something! Highly recommended!
Works well to store coffee and cut our energy usage per the coffee warmer, but we over paid on this item. Found something comparable for much less at a discount warehouse.
We love tea. So this airpot became a must-have item now.We just boil water once every morning. Then we keep brewing tea with the hot water out of the pot all day long until evening/dinner. If you need hot water all day long, this is the one worth to own due to the convenience and quality.
This carafe works great. As others stated, you need to put HOT water in the carafe for a short time to get it hot, then dump that water and pour your hot beverage in. We only needed hot coffee for about 5 hours during a party and it was still piping hot at the end of the night. I have not tried it for a longer length of time.
It holds all the coffee from a full carafe of a standard coffeemaker, unlike the thermal carafe I used for two days while waiting for this airpot to arrive. I would recommend this product to anyone who enjoys having hot coffee easily accessible all day long.
I was buying the Air Pot as a present for a friend who was frustrated with his current brand of carafe. I researched everything I could find regarding what made a quality beverage dispenser. I added this list to brands and the one I ultimately chose based on comparison of the two brands.My friend was very pleased and amazed with the quality of the Air Pot. As he is a Quality Engineer by trade this is a huge endorsement.
I purchased 2 of these as gifts for my daughters. The pot pumps well, but only keeps the coffee hot for a very few hours. I was hoping to have hot coffee for at least 8 hours. It is handy for its portability of taking hot coffee out to the patio or other places.
I have found that this will keep a hot beverage hot for at least 8-10 hours provided you preheat the dispenser first with some boiling or hot water. It is also very easy to pump the beverage out.I only gave it a 4 star rating because it is difficult for me to remove and replace the lid for emptying the dispenser for cleaning.Also it will occasionally  drip after pumping.All in all I'm pleased with this purchase.
Answer: Brenda, press the 2 buttons on either side of the top (like when you're ready to make coffee) and once the top is tilted at a 45 degree angle, you'll notice that the hinge of the top can be detached from the pot - just by pulling forward slightly should help it come loose. Hope this helps!
