The Brita UltraMax Large Water Dispenser is designed to offer an efficient at-home water purification solution. Its primary strength lies in the filtration technology that effectively reduces impurities such as copper, cadmium, and mercury, alongside the taste and odor of chlorine. This feature ensures that the water tastes better and is safer for consumption. With a generous 27-cup capacity, it is well-suited for families or individuals who consume a significant amount of water daily. The water dispenser is also space-efficient and designed to fit comfortably in a refrigerator, thanks to its compact dimensions and easy-locking lid. The precision-pour spigot adds to the convenience by making it easy to dispense water without spills.

Another notable aspect is the sustainability advantage, as using this dispenser can potentially replace up to 1,800 single-use plastic water bottles annually, aligning with eco-friendly practices. Maintenance is relatively straightforward with a sticker filter indicator that signals when it's time to change the filter.

It is also compatible with Elite filters, which last longer (up to 120 gallons or six months). However, the need for frequent filter changes could be seen as a drawback for some users. Additionally, although the dispenser is BPA-free, the use of plastic components might be a concern for those avoiding plastic products altogether.

The Brita UltraMax has a strong reputation, reflected in its high customer ratings and best-seller status, which indicates a generally positive user experience. This water dispenser is a great choice for those looking for a reliable water purifier with a large capacity and straightforward maintenance, though the frequent filter replacements and plastic construction might be points to consider.

Buying Guide for the Best At Home Water Purifier

Choosing the right at-home water purifier is essential for ensuring that you and your family have access to clean and safe drinking water. There are various types of water purifiers available, each with different features and specifications. Understanding these key specifications will help you make an informed decision based on your specific needs and preferences.
Filtration TechnologyFiltration technology refers to the method used by the purifier to remove contaminants from the water. Common types include Reverse Osmosis (RO), Ultraviolet (UV), and Ultrafiltration (UF). RO is effective for removing dissolved salts and heavy metals, making it suitable for areas with hard water. UV purifiers use ultraviolet light to kill bacteria and viruses, ideal for areas with microbiologically unsafe water. UF purifiers are good for removing larger particles and some bacteria, suitable for areas with low TDS (Total Dissolved Solids). Choose the technology based on the quality of your local water supply.
Water Storage CapacityWater storage capacity indicates how much purified water the unit can hold at a time. This is important for ensuring you have enough water available for your household's daily needs. Small families or individuals may find a capacity of 5-8 liters sufficient, while larger families might need 10-15 liters or more. Consider your daily water consumption and choose a purifier with a storage capacity that meets your requirements.
Flow RateFlow rate measures how quickly the purifier can process water, usually indicated in liters per hour. A higher flow rate means you get purified water faster, which is convenient for larger households or when you need water quickly. For small families or individuals, a flow rate of 10-15 liters per hour may be adequate, while larger households might benefit from a flow rate of 20 liters per hour or more. Assess your daily water usage and choose a purifier with a suitable flow rate.
Maintenance and Filter ReplacementMaintenance and filter replacement refer to the ease and frequency with which you need to service the purifier and replace its filters. Regular maintenance ensures the purifier continues to function effectively. Some purifiers have indicators that alert you when it's time to change the filter. Consider the availability and cost of replacement filters, as well as the ease of performing maintenance tasks. Choose a purifier that fits your comfort level with maintenance and has affordable, easily accessible replacement filters.
Energy ConsumptionEnergy consumption indicates how much electricity the purifier uses. This is important for understanding the long-term operating costs and environmental impact. UV and RO purifiers typically consume more energy than UF purifiers. If energy efficiency is a priority for you, look for models with lower energy consumption or energy-saving features. Consider your household's energy usage and choose a purifier that aligns with your energy efficiency goals.
Certification and StandardsCertification and standards refer to the endorsements and quality marks that indicate the purifier meets certain safety and performance criteria. Look for certifications from reputable organizations such as NSF, WQA, or BIS. These certifications ensure that the purifier has been tested and meets specific standards for contaminant removal and safety. Choose a purifier with recognized certifications to ensure you are getting a reliable and effective product.
