A bottleless water cooler might be one of the most convenient types of water coolers available on the market. Just think, no more having to deal with purchasing new bottles every week or loading a heavy 3-5 gallon bottle on to the top of the water cooler. Or having to carry them into your office.

These things are great and solve a huge problem.

Before we start, our #1 pick is the Avalon Self-Cleaning Bottomless Water Cooler (Link goes to Amazon). We’ll go over the details later on in the article. Just know that it is our #1 pick for the best bottleless water cooler dispenser.

Avalon Self Cleaning Bottleless Water Cooler

Avalon Self Cleaning Bottleless Water Dispenser

Alright, first up on our list, and our #1 recommendation, is the Avalon self-cleaning unit. You read that right, this unit cleans itself, which is why we love it.

Now, it does this cleaning by using ozone gas to sanitize and kill any bacteria found on the dispenser. Keep that in mind, this unit will only sanitize the dispenser. It won’t clean the rubber tubing or the canister inside. However, this is still convenient because many people will often forget to clean the dispenser.

It’s not so important if you forget with this unit. You should still clean it though.

Anyway, other than the self-cleaning feature it has a few other ones that we like a lot. It has three temperature settings, which makes it an effective replacement for a sink. You have room temperature water, cold water, and hot water.

What more do you need?

Let’s not forget about the filtration on this unit. You have a standard activated carbon filter that removes the rust, chlorine, and sediment from the water. This makes your water smell and taste great.

Some more great features include the built in nightlight that make it super easy to find the dispenser when it’s dark. You don’t even need to turn the lights on. We still recommend that though because stubbing your toe is painful.

One last thing, this has a child safety lock on the hot water dispenser. No risk for accidents. I mean, there is some risk. It’s just much less likely.


  • Self-cleaning makes it super sanitary
  • Three temperature settings
  • Nightlight to find it in the dark
  • Ideal temperature alerts.


  • Price.

Best For Two Temperatures: Avalon Self Cleaning Bottleless Water Dispenser 2 Temperature

Next on our list is another Avalon. These products really are the best on the market. They’re such a great company and always make the best products.

Ok. Anyway, this unit is basically the same as the previously mentioned one. However, this has 2 temperature settings instead of one, which bumps it down a ranking on our list. Granted, you can always mix the hot and cold water if you want room temperature water. That is kind of annoying though.

Self-cleaning is nice as mentioned earlier. It’s just an o-zone type thing that sprays on the dispenser. This kills bacteria, but it won’t kill you. There is even an indicator that light that shines when this cleaning process occurs. You know, just to let you know what is going on with your dispenser.

This also has the usual activated carbon filter. It should last about 6 months, but this depends on how much water you use. Less water is generally used with these because they don’t have any tap water available.

One last thing, this has the nightlight on it too. This is a feature that you find on most Avalon water dispensers. We here at Water Purification Hub really like this feature, but you can disable it if you want.


  • Self-cleaning
  • Activated carbon filter
  • Nightlight.


  • No room temperature setting

Longest Filter Life: Brio Commercial Grade Bottleless Filter Water Cooler

Looking for a bottle less water dispenser that has the longest filter life?

Of course you are. Everyone hates changing the filter on these things.

Fortunately, the Brio commercial grade dispenser has a long filter life to solve this problem. This system actually has a three stage filter.

Yes. You read that right. It’s a bottleless water dispenser with a three stage filter. So, this isn’t exactly three different filters. It’s really just two pre-filters before the activated carbon filter. It doesn’t really matter though.

Basically, this works by filtering a bunch of big contaminants through the pre-filter, which has more filter media. This has the effect of reducing the amount of contaminants that get clogged in the activated carbon media. In total this filters out 68 different contaminants, which is very respectable.

This unit also has hot, cold, and room temperature water. Very nice.

One last thing. This has a stainless steel door. A much added upgrade to the typical plastic that you find a water dispenser.


  • Three stage filter
  • Hot, cold, AND room temperature setting
  • Cold water is fairly cold (around 40 degrees)
  • Filter removes 68 contaminants
  • Stainless steel door


  • Short. You might have to bend down to get water.

Fast Fill Rate: Aquaverse A3500

Something a lot of consumers forget about is how long it takes to fill up a cup of water. You want to be in and out as soon as possible when filling up your water.

This is especially important for an office because it means that employees will spend less time at the water cooler. I mean, employees will still spend time at the water cooler, but they will probably spend less time at the water cooler.

The Aquaverse A3500 is extremely quick. You can fill up a 16 ounce container of bottle in 8 seconds. That is fast. Now, this number will vary depending on the water pressure on your water line. This just assumes ideal conditions. Either way it is still very good.

This water dispenser has more going for it than just that though. It has an activated carbon filter that will remove a bunch of different contaminants that make water taste and smell bad. Not to mention that it has dual float technology that decreases the likelihood of any flooding.  

Finally, it’s a nice deep black color that looks great. Not as good as stainless, but much better than plain white. I’ll give this a solid 4/5 on the looks scale for a bottleless water dispenser. Looks aren’t too important, but it’s still a nice to have feature.


  • Very fast water dispensing. 16 ounces in under 8 seconds!
  • Activated carbon filter (removes chlorine).
  • Black plastic looks good.
  • Dual float technology prevents flooding.
  • Great price.


  • No room temperature setting.

Best Bottleless Water Dispenser that won’t flood: Oasis POUD1SHS

Looking for a safe bottleless water dispenser. Oasis is your best bet. They make good dispensers so don’t worry about that. You still get an excellent quality product with this unit.

This unit has a few interesting features that we really like. First, it has a dual float system that helps prevent it from flooding. What often happens is that the water will just keep flowing and flood the entire unit. Remember, this is hooked up into the wall so if nothing is there to stop the water it will just keep flowing. This can result in some nasty flooding.

Not an issue with the Oasis.

It also has a super convenient removable drip tray, which makes cleaning easy. In addition to that, it has a two piece hot water tank. This is something that is unique to Brio and it makes cleaning these units super easy.

Finally, it has a super nice three year warranty. One of the best in the business.


  • Budget choice.
  • Three year warranty.
  • Dual float system prevents flooding.
  • Two temperature settings.
  • Energy Star certified. 


  • White plastic is ugly.
