Brita UltraMax 18-Cup Dispenser Review: Is It Worth It?

The Brita UltraMax 18-Cup Dispenser is the largest countertop water dispenser from Brita. Our editorial team compared specifications, buyer feedback and key decision factors to evaluate its filtration speed, taste improvement, filter life, capacity, and ease of use. We also compare it with other Brita models to help you decide if this giant dispenser is right for you.

Design and Build Quality

The UltraMax features a sleek, BPA-free plastic design with a large reservoir and a sturdy spigot. It measures 10.5 x 7.0 x 9.8 inches, making it one of the taller Brita dispensers. The handle is ergonomic and the lid seals tightly to prevent spills. The spigot has a push-button mechanism that is easy to operate, even with one hand. Some users report that the spigot can drip if not fully closed, but this is not a widespread issue. The transparent reservoir lets you see the water level at a glance, and the lid has a small opening for easy filling without removing the entire top. The build quality feels solid, with thick plastic that withstands daily use. The base has non-slip feet to keep it stable on refrigerator shelves. Overall, the design prioritizes functionality and durability over aesthetics.

Filtration Performance

The Brita UltraMax uses the same standard or Longlast+ filters as other Brita models. Filtration speed is notably slower than smaller dispensers due to the larger reservoir. When full, it takes about 1 minute to filter 1 cup. This means after pouring a large glass, you may wait a few minutes for the water to filter before the next pour. However, for many users, the trade-off is acceptable given the capacity. Taste improvement is consistent with Brita's reputation: chlorine and other impurities are reduced, resulting in clean, fresh-tasting water. The Longlast+ filter lasts up to 6 months, reducing replacement frequency. In our experience, the water tastes noticeably better than tap water, with no chemical aftertaste. The filter also reduces sediment and some heavy metals, though it does not remove all contaminants. For basic taste and odor improvement, it performs well.

Ease of Use

Filling the UltraMax is straightforward: lift the lid and pour water directly into the reservoir. The lid has a snap-fit closure that stays secure. The spigot is easy to use, though some users find it requires a firm push. The dispenser fits on most refrigerator shelves, but measure your space first. The large capacity means fewer refills, which is a major convenience for families or offices. The handle on the side makes it easy to carry when full, though the weight is considerable. The spigot design allows for one-handed pouring into glasses or bottles. Some users have noted that the spigot can be stiff initially, but it loosens over time. Overall, the UltraMax is user-friendly, especially for those who prioritize capacity.

Cleaning and Maintenance

The dispenser is top-rack dishwasher safe (except the filter). Hand washing the spigot with warm soapy water is recommended to prevent mineral buildup. The filter should be replaced every 2 months (standard) or 6 months (Longlast+). Some versions include a filter change indicator, but many do not, so set a reminder. To clean the reservoir, use a mild detergent and rinse thoroughly. Avoid abrasive cleaners that could scratch the plastic. The spigot can be disassembled for deep cleaning, though this is not necessary for routine maintenance. Regular cleaning prevents mold and bacteria growth, especially in the spigot area. We recommend cleaning every two weeks for optimal hygiene.

Common Buyer Complaints

• Slow filtration speed: many users note it takes a while to refill after pouring a large glass.
• Spigot dripping: a few reports of the spigot not sealing completely, causing minor drips.
• Size: the dispenser may not fit in smaller fridges or on narrow shelves.
• No filter indicator: some models lack a reminder, leading to overused filters.
• Plastic taste initially: a few users report a slight plastic taste when new, which dissipates after a few uses.

Comparison with Other Brita Models

Compared to the Brita Everyday 10-Cup Dispenser, the UltraMax holds nearly double the water but is slower to filter. The Brita Stream 7-Cup is faster and more compact, ideal for individuals. The Brita Grand 10-Cup offers a middle ground. For those who prioritize capacity over speed, the UltraMax is the best choice. The UltraMax also has a larger footprint, so it may not fit in all refrigerators. The Everyday and Grand models are more space-efficient. In terms of filter compatibility, all models accept the same filters, so you can use Longlast+ in any of them. The UltraMax's main advantage is fewer refills, which is a significant convenience for heavy users.

Value and Long-Term Use

The Brita UltraMax is priced higher than smaller dispensers, but the cost per cup of filtered water is lower due to the larger capacity. Over a year, you will replace filters less frequently if you use the Longlast+ option. The dispenser itself is durable and should last several years with proper care. Replacement filters are widely available and reasonably priced. Considering the convenience of having a large supply of filtered water on hand, the UltraMax offers good value for large households or offices. However, if you only need filtered water for one or two people, a smaller model may be more cost-effective.

Final Verdict

The Brita UltraMax 18-Cup Dispenser is a top performer for large households or offices that need a steady supply of filtered water. Its main trade-offs are slower filtration and larger footprint. If you have the fridge space and patience for refills, it delivers excellent value. Check the current price on Amazon to see if it fits your budget.
