Not only does the Ullo Wine Purifier aerate your wine, but it uses Selective Sulfite filter technology to purify it too. The liquid glides easily through the disposable sulfite filters and then spirals around the dome-shaped base, introducing air to your wine. We were pleasantly surprised to find that the sulfite filters provide no unwanted change in taste. We tested this out by aerating the same wine with and without the filters for a side-by-side comparison. The swirling of the wine, which takes place in the bulbous base, takes the edge off the tannins, leaving room for fruity and oaky notes to shine brightly. The Üllo is very quiet, so if you prefer to taste, see, smell and feel your wine without having to hear it, too, then this is a great option. 
This in-glass wine aerator is extremely easy to use. It simply sits on the rim of your desired wine glass. The top half is made of rubber and is tapered to ensure a gentle fit for a wide array of delicate glassware. It is best to pour slowly, but generally speaking, the large-sized mouth is difficult to spill. Unfortunately, the in-glass aerator is not a great option if you plan to refill used glasses because it comes in contact with the rim. That renders the Üllo a difficult one for large dinner parties or group gatherings. That being said, for personal use, small intimate gatherings, or for events that require a fresh glass with every pour, the Üllo is a splendid option.
