Mask , I know you!

  Today we are talking about a care against viruses as masks and respirators, a how they are too effective, and which time am need to wear  theirs, and right selecting theirs and levels for protections and saving.

Breath organs protections you can with two methods as filtrations and    isolations, and to the second are gas masks, as using in most dangerous cases as in chemical contagion of air, as on harmful factory, thus they are individual items for protection of breath organs/IIPBO/ which are filtering breathing air against dust and harmful for health substances. And these are respirators as respiration is breath, are textile half masks, and apparatus with a special filters and valves.

And these are guaranteeing by quality certificates as hygienic item rate, and they are effectivity just right by instruction.

A most simple models for filtering respirators are access in exploitations as disposable half masks. They are protecting from dusts, bacteria, transferring by air-dropsy way, and using at work, and households.And same by a construction half masks for using many times are sterilizing after work, having a many times using and note in instruction and limiting with a few times for exploitations.

Respirators with a filter attaching. A half mask of filtering material and protect breath organs against dust and aerosols as in air by factories, and production places.And  here are too having moulded and non-molded  as on a face straightening on the face, as in construction like a IIPBO and enters in nasal climb for a fixating mask is on the face and valve for breathe out for preventing filling a humidity is under mask space.

Respirations with replaceable filter.

Of plastic isolating material, having a hard form and valves for breath in side holes, where entering are re[lacing filters, and in low side a mask is having valves for breathe out.

These are all kinds of respiation half masks are using at work, and in household as fpor patiens care, gardening and building.

By classification, a gosts for 2015  are these masks having three classes and designating is  depending on from theirs filtering effectivity.

FFP1 is low activity, level for protect are 60 percents, and wear time till 6 hours, and without valve, just disposable, protecting from dusts and aerosols, less sizes are holes for filtering material. 

FFP2 is middle effectivity, level for protection are 70 percents, wear time are 6-8 hours, and with valve, and disposable, and protect from aerosol, humidity, finely dispensed parts and partially giving protection against viruses and using in spa, hospitals, but lots of peoples are hard breathing through theirs for the long time, and material is not designed for the long exploitation at humidity conditions.

FFP3   is high effectivity, till 80 percents a level for protection, wear time are 6-8 hours, as disposable with valve, which is   real protecting from viruses and bacteria, and most often exploiting with protection glasses, but a breath in these masks without a skill right is hard in a hour.  And in a selling you can meet China s models as with mark Protection   NR95 ,  ARE keeping 95 percents air by an air-dropsy parts by a matching for respirator class FFP 2.

From a one is household respirators are medical respirators as tighter attaching to face, closing nose , mouth, chin, and reliably fixing on occiput with belts. And also having for disposable with a changing filters for brethe in, and breathe out, and serving for the long time as in disinfecting . These are cleaning breathe in air from parts as on sizes 0.04-1.3 mkm/micrometres/, and microbes all kinds having in this interval, doctors are wear these IIPBO ARE on the epidemic times.

For protection and preventing diseases and not just are medics, are activity using medical masks with following kinds:

Gauze reusable  , level for protection are 20 percents, wear time 2 hours, simple variant using in a straight contact  with patient, but very old kind, but plus is keeping for disinfection long, and long time using.

Fabric mask.

Protection level are 20 percents, wear time are 2 hours, and not  reusable, as not tighter matched to face, not filtering layers having and made of synthetic fabric, which not boils, manufacture by ultraviolet rays and in result this mask staying a favourable soul spreading microorganisms.

Medical mask of three layers. Protection level are 40 percents, wear time are 2 hours, as very spreading masks type selling in pharmacy , and using by junior medical personal, effectivity against dust, bacterias are good, but this mask is often to change as she is faster filling with humidity and a staying for source are microflora spreading.

Medical surgery mask.

Level for protection are 40 percents, wear time are 2 hours, four layer mask, need a full attaching to face and wear right and not enjoys beards, and if in other models comfort for weak keeping 20-40 min, thus this mask keeping this stat are 2 hours.
