The Kn95 mouth guard is the most popular and effective aerosol respiratory mask for serious allergy-induced rhinitis. Its official name simply means that it can effectively block more than 95% of airborne particles below 0.3 microns. This translates to truly safe performance in terms of protection, especially in the workplace. This is also a great feature for those with dust allergies, as it makes it easier to breathe allergen free.

The kn95 masks come in both disposable and non-disposable varieties. A disposable mask usually works better than the non-disposable variety because they can be used on a regular basis and thus can be preserved longer. In terms of longevity, the best brand that offers a durable and long-lasting disposable mask is the Invacare Dermal shield with the patented DuraSeal technology. A non-disposable kn95 mask on the other hand, can be cleaned easily using water and soap while being worn on a daily basis. Some even come with a sliding cover which makes cleaning easier, but in some cases, it may be necessary to replace the entire cover in less than one year.
The overall cost of the Kn95 masks is generally quite affordable, however the more popular brands such as the Invacare Dermal Shield with DuraSeal technology have become quite pricey due to their popularity and durability. Some of these brand masks offer a lifetime warranty, but there are still others which offer a limited time warranty. You can even find cheaper knock offs of these famous brand names if you look hard enough. It is therefore essential to do your research well before making any purchases, especially since purchasing a mask which may not necessarily be suitable for your allergic conditions can lead to further complications down the line. This is why it is recommended that you do some research about the product or company you intend to purchase the mask from.
