1. What size particles does the Techno™ mask filter out?

The Techno™ filter has sub-micron filtration capability. What this means is that it is able to trap particles less than one micron in size which is more than capable of the removal of 2.5 micron particulate material (PM).

Typically particulate pollution in the cities appears to be in the 2.5 micron size range and above. Particles smaller than this are known as respirable dusts, which can lodge deep within the lungs and air sacs. This is the more dangerous type of particle pollution as chemicals from vehicle exhaust gases combustion known to be toxic, are carried by means of the respirable particles. Hence the need for a Hepa-type™ submicron particle filter.

The DACC™ Activated charcoal layer within the Techno™ filter has excellent adsorption properties when it comes to SO2 and NO2 uptakes. With this capability and its capability of filtering VOC’s it is the best filter available in our range for dealing with the broad spectrum of pollutants commonly found in major cities across the globe.

2. What size mask do I need?

Please refer to the following chart for a sizing guideline.

If you are unsure if the mask will fit, you can measure yourself as explained in the following sizing chart. Please email the measurements to us and we will reply within 24 hours with your correct sizing.

3. Are children’s masks available? 

Sorry, Respro do not currently provide a range of masks for children.

4. Do the filters need replacing, if so, how often?

Yes, the filters do need replacing.

The effective working life of Respro® filters depends on a number of factors, such as; the breathing rate of the user; ambient levels of pollution; the length of time the filter is actively working; hygiene levels. Taking these factors into account we recommend that the filter should be replaced every month or every 69 hours, whichever is sooner.

5. How do I change the filter?

The video below shows how the filters and valves are replaced.

6. What filter do I need?

You will need to determine what type of environment you will be using the mask in, i.e., a city environment or a countryside environment. Typically, if you are commuting every day with heavy or slow moving traffic, you should use the Techno™ filter.

7. Are all the filters and valves interchangeable?

Yes! All our filters are interchangeable, provided they are the same size. You can make your own mask from a combination of parts. like the Sportsta™ mask with Techno™ or City™ or Cinqro™ filter or Allergy mask with Powa™ Elite valves.

8. Do I need to replace the valve?

The valves should not need replacing on a regular basis assuming that they are maintained properly. On a monthly basis, it is advisable to flush the valves through with warm water, allow to dry and apply a little talcum powder to prevent the valve from sticking. On the Powa valve, it is essential that you locate the two pins, nearest the hinge, properly into the body of the valve, and check that they are seated properly.

9. Can the mask be washed?

It is recommended that you wash the neoprene shell of the mask every month under normal use. To do this it is necessary to remove the filter and the valve first. Although spare valves and filters are available from your retailer, please be careful not to misplace any of the components during maintenance.

10. These bendy nose clips, how far should I bend them?

The malleable nose clip deforms easily so that a good fit can be formed around the bridge of the nose. Continuous or exaggerated deformation will eventually cause failure in the metal - it will snap. Once a good fit has been found, it is best to maintain the shape, rather than folding it flat when storing it or when not in use. 

11. How do I stop my glasses from misting up?

When using a mask with glasses, it is best to fit the mask first to get the correct fit with no seal leakage, then place the glasses in front of the nose clip on the mask. It is really dependent on the seal of the mask. Having adjustable nose pads facilitates a better fit than plastic moulded rims. A good seal around the nose and cheekbone will mean no leakage in that region which equals no misting. This is how/why glasses get misted up on the inside of the lens. In our experience most glasses wearers manage to figure a way of fitting glasses with a mask without them getting misted up.

12. I feel my breathing is restricted is this normal? 

We think that from the start that you have to understand that any mask will have some level of restriction especially at fast breathing rates for example; when cycling fast.

All of our masks are compatible with aerobic exercise. If you body starts working in an anaerobic capacity then no mask is compatible and you will feel like you need to stop or slow down.

The best masks will use exhalation valves that ‘dump’ heat, water vapours and Co2; the quicker the better. The removal of these components is the key to comfort. You need to get them out of the mask. The Powa™ and Powa™ Elite valve is key at elevated breathing rates.
