Q1. What Mask is best for me?

A1. When determining the best mask for you, it's important to think of the mask as a reusable shell that holds the replaceable filter comfortably in place. All masks come stocked with the F1 Active Carbon Filter, in terms of filtration, all masks are the same. The activity that you are doing and environment you are in along with the period of use will determine which mask or essentially shell is best for you. Here is a breakdown of the characteristics of each of our available masks.

Our M1 Mask is constructed out of Neoprene and is ideal in cold to mild weather. It's also ideal for a lower intensity activity. The mask is secured to the head with a single strap around the back of the neck. This allows the user to quickly and easily apply and remove the mask.

Our M2 Mask is constructed out of a breathable mesh material which is ideal in mild to warm weather. It's also ideal for a higher intensity activity where you may be working up a sweat. The M2 has the same single strap as the M1. Ideal for shorter periods of use (up to 2 hours).

Our M2.5 Mask is also constructed out of the same mesh material as the M2 however it has two adjustable elastic straps. One for around the back of the neck, and one for over the crown of the head. This second strap causes slightly more time for applying and adjusting the mask to fit properly, however it adds increased securement giving the user increase in mobility. Ideal for long periods of use (2 hours+).

Q2. What Filter is best for me?

A2. We carry three different types of filters. All Masks come with our F1 Standard Active Carbon Filters which carry a 99.9% efficiency down to .1 micron. This filter is effective towards dust, fumes, odors, smoke, allergens, organic chemicals and more.

Our F2 and F3 offer increased breathability compared to the F1. They both carry a 99.9% efficiency rating down to 0.1 micron. The F2 does not carry any active carbon leaving it effective only to dust and allergens. The F3 does carry an active carbon element causing it to be effective towards fumes, odors, smoke and organic chemicals in addition to dust.

The F2 and F3 are geared towards the higher intensity user where you may be building up a sweat since they have 40% less resistance than the F1 standard filters.

All three of our filter types are compatible with any of our three styles of masks.

Q3. How long do Filters last?

A3. The life expectancy of the RZ Filter depends on many variables, such as; particulate exposure density, particulate exposure duration, user breathing rate. With that said; below are our general guidelines:  As the user you will have the final call given your exposure.

  • 20-30 hours of continuous use in heavy dust exposure to Grain bins, Off-road, construction/demolition etc.
  • 30-40 hours of continuous use in light dust exposure to Grain Bins, off-road, construction/demolition etc.
  • 50-60 hours of continuous use when protecting against allergens, pollutants, odors etc.

The lifespan of the Active Carbon in the F1 and F3 filters will depend on what you are using it against and the concentration of the matter in the environment. It is recommended to change the filter if you notice any odors coming through the filter.

It is recommended to store your F1 and F3 filters away from a contaminated area.

Q4. Can you wash the filter?

A4. Our filters are not washable. We recommend replacing your filter for maximum breathing protection when the active carbon has been depleted / Or visually the filter has been exhausted due to dust and other airborne particulates.    

Q5. How do you ship your orders?

A5. We process all orders within 2 business days of receiving. We have several different options for shipping. We ship USPS First Class Mail for free for all US orders. We also have paid options including USPS Priority Mail, UPS Ground, UPS 2nd Day and UPS Next Day. International orders are shipped with USPS or UPS.

Q6. What is your return policy?

A6. We have a 30-day money back guarantee. For exchanges, we request that you contact us within 30 days of receiving the mask. We will need the original mask mailed to us prior to shipping out a new one. 

 Q7. What is your sizing guide?

A7. We offer 3 sizes currently: Medium: Up to 125 LBS // Large: 125lbs - 215lbs // XL: 215lbs and Greater. There is also a sizing guide available on each product page, simply click the “Sizing Guide” link.

Q8. How do I replace the filters?

A8. The filters can be replaced by turning the inside of each valve, counter-clockwise. Each filter is affixed in between the valves. Once removed, the old filter can be disposed, and the new filter can be placed in between the two valves. Turn the valves clockwise until they are tight.

Q9. Is the mask washable?

A9. Yes, the mask can be washed. We recommend hand washing the shell with hand soap and warm water. Allow the mask to dry completely upon washing.

Q10. Is the mask NIOSH approved?

A10. Our masks are not NIOSH approved. The filters have been independently tested at Nelson Laboratories in Salt Lake City, UT and tested at 99.9% efficiency against particulates down to .1 microns is size. Our Official Test Results are available on our website on any product page. Just click on "Filter Test Results" to view them. We are in the early stages of NIOSH Certification and will be sure to announce our approval when it is achieved.

 Q11. Do the masks work with beards?

A11. As we all know it is impossible to create a full seal in any mask if the user has facial hair, but the shape and design of our mask allows the user to create as much of a seal as possible. It is recommended to be clean shaven.

 Q12. Will the mask fog my glasses?

A12. As long as you have the correct size mask and have adjusted the nose piece to create a seal at the top of the masks the one-way discharge valves on the front of the mask will allow all the condensation to escape which prevents fogging.

Q13. Can the mask be used against silica?

A13. Our masks are not recommended for use against silica, asbestos, lead, arsenic, cadmium, MDA, abrasive blasting or any other toxic and/or dangerous substances.

Q14. Are the masks BPA free?

A14. Our masks are BPA, lead and latex free.

Choosing the correct mask size

To determine the correct mask size for your facial structure, we recommend taking exact measurements using the method described below.

  1. Measure from the bridge of your nose to just under your chin. *See guide below. (It may be helpful to have a friend assist you)
  2. Use the measurements you have taken and match to the best fit from the below:

NOTE: If you are on the bubble based on measurements - refer to weight.

  • Extra Large (XL) - 4.5" - 5.5"   |   215lbs +
  • Large (L) - 4" - 4.5"   |   125lbs - 215lbs
  • Medium (M) - 3.5" - 4"   |   Up to 125lbs

 Filters are designed to match your chosen mask size, i.e. Extra Large (XL) mask houses an XL filter.

Below is a general guide based on body weight  (note that facial measurements are more accurate for ensuring correct fit).

  • Extra Large - 215 lbs +
  • Large - 125 lbs - 215 lbs
  • Medium - Up to 125 lbs




 Fit Guide

A proper fit is key to efficient filtration and prolonged comfort. There are a few tips and tricks to help fit your mask properly. Please refer to below image for proper fit.

  1. When applying your mask, place the top most part of the mask on the very top of your nose, then lower to cover your mouth and chin. Finish by fastening the strap(s) in a comfortable position. TIP: If you feel pressure on the top of your nose, fasten the strap in an "upward X" position. Vice versa for pressure on the bottom of your chin. 


  1. A proper seal is only required on the filter, not the mask shell. See image below. As you notice, the filter (blue) is creating a seal on the users face while the mask shell has some slack. This is acceptable. As long as the filter is creating a seal, the mask is deemed effective.
