RO water purification is not required for all water sources. For example, suppose your municipality supplies your homes with RO-purified water through its pipes. You can save on additional costs by installing a UF water purifier like the KENT Gold Optima Gravity Water Purifier.
This water purifier should suffice to remove the sedimentary contaminants that your water could pick up on its way to your homes.

Cons of KENT Gold Optima Gravity Water Purifier

Our Opinion
The KENT Gold Optima Gravity water purifier is excellent if you get good quality RO-purified water in your taps. The UF technology should suffice to remove whatever contaminants the water might gather on its way to your homes.
This water purifier does not use chemicals to purify water, so it ensures hygiene. Besides, the carbon filter removes the foul odor, while the UF membrane takes care of contaminants as tiny as 0.1 microns.
Though the appliance is convenient, it has drawbacks, like manual operations and frequent filter replacements. In addition, you have to monitor the water level in the lower tank and ensure to fill up the top container accordingly. Filling up excess water can cause the water to overflow.
The product is suitable for single individuals or couples. The 5L pure water capacity is on the lower side. Nevertheless, its performance is good. Hence, you can purchase this appliance for your kitchen.
This water purifier has WQA and USA gold seal certification. So, it is an ideal entry-level water purifier for your kitchen.
Design
The exciting feature of the KENT Gold Optima Gravity water purifier is its sleek look. The transparent tanks allow you to gauge water levels quickly. In contrast, it is impossible in stainless steel or aluminum body water purifiers.
The body is made of ABS food-grade plastic and is durable. The appliance is light and compact. But, the pure water-holding capacity is low because the tank cannot hold more than five liters.
The manual operation is a significant drawback, but it is the same with all gravity water purifiers. The benefit is that it does not consume electricity.
The 5L capacity makes it an ideal water purifier for small families, couples, or single individuals. In addition, this countertop appliance does not occupy much space in your kitchen.
If your water source has TDS levels of less than 250ppm, this water purifier should be an ideal choice.
Performance
Considering its limitations, the Kent Gold Optima delivers a decent performance. It works on UF technology that cannot handle TDS levels of more than 250ppm in the source water. However, it comes equipped with a UF membrane capable of filtering contaminants as tiny as 0.1 microns.
While the UF membrane traps sediments and minute impurities, the carbon filter absorbs organic impurities and improves the purified water’s taste.
The nano silver carbon filter needs replacement every three months, and so does the sediment filter. But, the UF membrane can last for six months, depending on the TDS levels in the water source.
Kent claims that the UF membrane requires replacement after purifying 4000 liters of water or after six months, whichever is earlier.

Installation and Service
Installing the water purifier is not an issue because it does not require any technical background. Similarly, replacing the filters is easy.
Initially, the pricing is attractive. But, frequent filter replacements increase the operational cost substantially. Cleaning the water purifier is convenient. However, we recommend cleaning it frequently because the plastic materials can give a unique smell if not properly maintained. Kent offers a one-year warranty on the product.
