The InSinkerator Evolution Excel vs Prestige: Choosing Between Two Quality Garbage Disposals...

Design and Construction

Garbage disposals are not meant to be beautiful or appealing to the eyes. For one, their sole function is to get rid of messy food remains dumped into the sink. Secondly, they are usually installed under the sink, not to be admired by friends and visitors. It would therefore come as a surprise that these InSinkErator units actually look nice. They have a sleek, modern, and professional appearance that totally screams efficiency.

Not only are these disposals well designed, they are also superbly constructed from the finest materials to ensure they last for a very long time. None of their component parts are made from plastic; everything is stainless steel, from the grinding chamber to the mounting flange. Heat and moisture within the grinding chamber could cause it to start corroding, but thanks to its stainless-steel construction, you don’t have to worry about corrosion in your unit’s chamber. Both disposal units also come with a stainless-steel exterior.

It is important to point out that in terms of design and materials used in construction, there is no difference between these two products.


The stainless-steel exterior of both units sports an elegant gray finish.

Feed Type

Both garbage disposal units are designed for continuous feeding. So, you can keep on adding waste into the unit even when it is running.

Grinding Performance

Both the Prestige and Excel are models in InSinkErator’s highly acclaimed Evolution series. This means that their grinding performance is one of the best you can find in the market. They are designed with a multiple grinding stage technology consisting of three grinding stages for complete and efficient waste disposal. The incoming waste is moved from one stage to the next until every bit of food is pulverized into the smallest particle possible. Once the grinding stages have been completed, you can be very sure that the end product would be virtually incapable of clogging up your drainage system.

The grinding efficiency of these InSinkErator units makes it possible for them to get rid of tough waste that would ordinarily cause the disposal to jam. Vegetables and even bones are no match for these garbage disposals.

Induction Motor

The Prestige and Excel are two of the most powerful garbage disposals in the market thanks to their 1 HP induction motor. This high-powered motor ensures the unit can handle any garbage thrown at it on a constant basis.

Power Cord

Rated as 120V, 60Hz electrical appliances, these garbage disposals need to be connected to a power outlet capable of supplying the required current of 10.2 amps. In essence, you need a power cord for these units to work. Depending on the store or retailer, you can get the Excel with or without a power cord. When buying the Prestige, you get no power cord. You have to buy it separately.

Sound Insulation

With powerful motors come much noise, or so the saying goes. But the InSinkErator Prestige and Excel are exceptions to this rule. Both units are designed with a SoundSeal technology that reduces the noise output. With their sound insulation, you will experience roughly 50% less noise than similarly-powered disposals from other brands. It’s a win-win situation with these InSinkErator Evolution disposals; you get a powerful unit that is ultra-quiet.

Jam-Sensor Circuit

Despite the in-built grinding technology and good intentions of the manufacturer, jams within your InSinkErator garbage disposal unit may still occur. The Excel is therefore designed with a sensor circuit to eliminate jams. This circuit detects a jam and immediately increases the unit’s rotational torque and pulsing action, effectively breaking up the jam. The Prestige lacks this important feature.

Auto-Reverse Feature

With no jam-sensor feature, the Prestige is highly disadvantaged when it comes to getting rid of jams. It however makes use of the auto-reverse grind feature to eliminate clogs as best as it possibly could. The unit can automatically reverse its grind direction when the incoming waste gets stuck and begin to clog up the grinding chamber. The Excel also comes with this auto-reverse grind feature.

Ease of Installation

Both units come with a Quick Lock mounting system that makes installation easy and straightforward. Even if you’re replacing your former disposal unit with any of these two InSinkErator garbage disposals, the Quick Lock mounting system comes to the rescue and saves you from undue stress.

Restricted Purchase

The Prestige and Excel are very similar models, separated only by the jam-sensor circuit in the latter. Now, while you can buy the Excel unit from many hardware stores that carry small appliances for the kitchen and home. The Prestige can only be purchased at Lowe’s. This is the reason why the Prestige is sometimes called Lowe’s InSinkErator Evolution Prestige; it is sold exclusively at Lowe’s.


Both units are covered by a 7-year limited warranty. Long warranties such as this are a good sign as it means that the company stands behind its products.

The InSinkErator Prestige and Excel look the same even to a very keen observer. The jam-sensor circuit found exclusively in the Excel is the only difference in the operations of both garbage disposals, and it is a major deciding factor in my opinion. If both models are similarly priced, then buy the Excel as it offers you more bang for your buck. You can also check out our comparison of the supreme and excel.
