Approved by the National Institute for Occupational Safety & Health (NIOSH), the reusable N95 envo® mask respirator is designed for superior comfort and seal.

Each kit includes an N95 envo® mask respirator with the following features:

  • A lightweight plastic body that enables easy cleaning and filter changes.
  • Patented, latex-free AIRgel® cushion technology that contours around the face, providing secure, all-day comfort and freedom from foggy eyewear.
  • Exhalation valve that allows for a cooler breathing experience with less resistance, while the provided plug offers users the option of two-way protection.
  • One adult size designed to fit most faces. If you are taller than 5’2” and shorter than 6’2”, it is likely that the mask will fit.
  • The envo® mask measures approximately 4 inches (10 cm) from top to bottom and 5 inches (12 cm) from side to side.  The mask should rest easily on the bridge of your nose, cheeks, and chin.  For those with petite facial features, a larger than average or elongated nose, or a wide and flat nose bridge, the mask may not fit or obtain a seal.

The kit also includes:

  • Five (5) individually packaged filters that remain electrostatically charged until ready to use. Each filter has a ten-year shelf life, allowing for long-term storage.
  • An optional vent plug that enables users to filter their exhaled air.
  • Your choice of a traditional Holo head strap or QuickFit earhooks.
  • A slim case for easy transport.

Note: Only envo®mask N95 filters are compatible with the envo®mask respirator body. No other filter may be used with the envo®mask body, regardless of fit. Please dispose of filters immediately following contamination or damage.

Which headgear comes with the envo® mask respirator?

When ordering on envomask.com, you may choose between the Holo or QuickFit headgear. The Holo headgear is automatically the default option if you do not select a headgear.

Where are your respirators manufactured?

Sleepnet Corporation manufactures the envo® mask and the envo® pro in the USA at its headquarters in Hampton, New Hampshire.

Where do you ship?

We currently only ship to the United States and Canada.

What are the envo® mask filters made of?

The envo® mask N95 filters are four layers, including proprietary fibers, making the envo® mask one of the lowest resistant masks on the market. Lower resistance equates to easier breathability.

What is the warranty for my envo® mask or envo® pro?

Envo® offers a 90-day warranty against manufacturing defects.

What is the purpose of the vent plug on the envo® mask?

The vent plug provides two-way protection in the envo® mask that comes with an exhalation valve. Without the plug, the mask with an exhalation valve protects you from environmental particulates only. If you choose to use the plug, it will protect others from your air droplets that may carry a virus. The vent plug installs inside the filter cover and plugs the vent holes. If you purchase a mask without an exhalation valve, you do not need to use the vent plug.

What is the purpose of the envo® mask shield?

The envo® mask shield is a physical barrier that protects the filter. Install the shield by clipping it onto the mask’s filter cover. It is an added measure of protection for those working in harsher environments.  The shield only works with the envo® mask respirator.

What is in the envo® mask kit?

Each envo® mask respirator kit comes with a mask body, filter cover, five N95 filters, vent plug, storage case, and choice of headgear: Holo or Quickfit.
  • Mask body: The mask body is the main component of the mask, with an interior gel cushion and outer plastic frame that holds the filter.
  • Filter cover: The filter cover is a plastic frame that holds the filter in place on top of the mask body.
  • N95 Filter (5): Each kit comes with five filters that are N95 certified by NIOSH.
  • Vent Plug: The vent plug is a white plastic plug that installs inside the filter cover and plugs the vent holes.
  • Storage Case: The storage case makes it easy to keep all of your mask components clean and in one place.
  • Choice of Headgear: The Holo headgear fits on the crown of your head. The QuickFit headgear has hooks that fit around your ears.
