Pillow cover is what people, in general, know as a sheath or covering for their pillows and keeps themselves from being directly in contact with the pillow.

This is the most common covering used for pillows and is known to be sold along with bed covers or bed sheets as a pair of one or two pillow covers.

Pillow protector is not commonly known to people as it is usually prescribed to individuals who have known allergies to dust and other such particles.

Hotels and resorts that have a certain level of ratings would certainly have enough hygienic practices to provide the guests with pillows properly encased in pillow protectors. It is not always used by individuals at home.

It also comes in varying sizes and shapes along with a multitude of colors and shades that could be chosen depending on the taste preferences of each user.

Their main purpose is to protect the pillows from external dust and many other external factors that surround the pillow.

These external factors can also include saliva that might come out in the form of drool which might have a hint of sugary taste or even other different flavors.

Pillow covers wouldn’t be able to cover a pillow completely as it might leave a small gap leaving the pillow open to infection or attack by foreign agents.

Such support in the form of protection enables the users to constantly change the pillow cover thereby ensuring hygienic practices for the user.

What is Pillow Protector?

Pillow protectors are generally used to create a physical barrier between the plain cloth of the pillow and the external environment.

It is not common for people to use pillow protectors at home as it is not much known to them.

On the other hand, resorts and hotels of some minimum standard would be known to add this additional support to their bedding as it would be perfect to ensure a safe and hygienic stay for their guests.

The major purpose of the pillow protector is to ensure that the user is kept away from allergens and from pathogens that might accumulate on the pillow from many sources such as the digestive tract.

Pillow protectors completely cover the pillows leaving no space open to the outside world. This is achieved by using zip locks or velcro tapes.

Sometimes dust particles along with dead skin cells that might fall off when someone is sleeping can cause an increase in acne or pimple formation on the user.

This can lead to multiple skin issues for the user and is therefore advised by dermatologists to use pillow protectors for hygienic purposes.

Along with such acne issues, people also tend to be highly allergic to dust particles and oil particles which might form a layer over the pillow.

These types of allergy problems can be solved by the use of pillow protectors which are again advised by dermatologists for the safety of the user.
