If the Covid-19 pandemic has taught us anything, it is that we should reduce our exposure to things, at least until everyone is vaccinated. At this year's CES, there are a number of products on display, from toilets to video doorbells, that do not require touching in order to use.

Touchless products are not new, but the pandemic has certainly accelerated their development over the past year. Here are some of the strictly touchless products that were presented at the 2021 CES.

LG's Instaview refrigerator (a large refrigerator that lets you see inside when you knock on the door) has a 23% larger window, allowing you to see more of its contents. However, the refrigerator has also received several pandemic-related upgrades.

First, you can ask Instaview to open the refrigerator door. This is useful not only to keep germs away from the handle, but also if you are carrying groceries. One can also use one's voice for other purposes, such as requesting a calendar.

Another great new feature is the UV light built into Instaview's water dispenser. According to the company, it should be able to remove up to 99.99% of all bacteria after 24 hours.

Pricing and release date have not yet been determined, but the current Instaview refrigerator starts at about $3,000.

Kohler introduced the Sensate touchless kitchen faucet two years ago, and now the company is bringing the same technology to the bathroom.

The touchless bathroom faucet comes in two versions. One is natively voice-activated, but there is also a retrofit model that uses a button that can be operated by any Kohler single control faucet.

Pricing for both versions has not yet been announced, but is expected to be less than $100. But you will have to wait: neither will be available until December.

Kohler has already launched a number of touchless intelligent toilets, all of which are prohibitively expensive, costing over $3,000 each. This includes the upcoming Innate Intelligent toilet ($3,100, available in June), which has a heated toilet seat, automatic lid opening and closing, and built-in bidet.

However, the company has also announced more affordable touchless models, ranging from $600 to $1,000. When you hold your hand over the lever next to the toilet, the water flows on its own. There is also a blue LED light around the lever.

You'll still have to open and close the lid yourself, but you won't have to wait too long, as this toilet will be available in March.

Like Kohler's smart kitchen faucet, Moen's smart faucet is voice-activated, so you don't have to use your hands when your hands are dirty with fabric or clothing.

Aside from turning the faucet on and off, it can also dispense precise amounts of water, from a tablespoon to a gallon, and specify a temperature.

In addition, the Moen app can be used to create presets for specific amounts, such as water bottles or pet bowls. Tell it that you are washing your hands, and the water will run for the appropriate amount of time. It also works with Alexa and Google Assistant.

Moen's smart faucets were launched last year and now come in a number of finishes and styles. They all start around $650.

Arlo's latest doorbell is not significantly different from the current offerings featured on our best video doorbells page. However, when this touchless model detects a visitor, it emits a sound and turns on a light to let the person know that they do not need to press a button on the doorbell itself.

Arlo did not say when this doorbell will be available or how much it will cost, but given that the company's other video doorbells cost around $150, this model is expected to be in the same price range. Presumably, the company will be able to achieve the same functionality in its current video doorbell as in the touch-free version.

In addition to its Wellness Toilets, which analyze poop, TOTO has introduced a new Washlet model that not only operates hands-free, but also has a built-in bidet and other features to clean and sanitize the toilet.

The Washlet models come in several styles, floor- and wall-mounted. Some models add a bidet and seat to other TOTO toilets (starting at $675), while others are integrated with the toilet itself (starting at around $2,200).

This touch-free video doorbell is very similar to other video doorbells sold by Alarm.com, but this model has a faceplate that tells visitors that they do not have to press a button to activate it. [The camera has a 1080p resolution, a 150-degree vertical field of view, HDR, and infrared night vision; within the Alarm.com app, homeowners can draw a virtual zone, and when someone steps into that area, the video doorbell is activated. [The video doorbell costs less than $200 and is sold through Alarm.com's network of home security providers.
