Respirators are personal respiratory protection equipment (RPE) against dust, gases, harmful, poisonous substances. Analyzing the rating of the best respirators and dust masks for 2024, you can choose a quality product that is suitable for the price, working conditions.

The first effective means of protecting against dust appeared thanks to Leonardo da Vinci, Alexander Humboldt (16-18 century). The respirators were made of a cloth soaked in liquid, or a bag that covered the head and had holes for the eyes.
Moistened cotton and wool served as an additional filtering agent. The cleaning of harmful gases was carried out with lime and activated carbon. Chemist John Stenhouse (Scotland) invented the first respirator with an activated carbon filter. Fire respirator developed by John Tyndall (England, 1871) consisted of two layers: carbon, wool (soaked in calcium hydroxide, glycerin).
Respirators are classified as personal protective equipment (PPE) along with overalls, goggles, gloves.
The respiratory organs (nose, bronchi, lungs) can be exposed to different threats, exposure to substances (leading to diseases):
Modern respirators differ in different ways:
From the time of application, there are:
Respirators differ in protection mechanisms, the way polluted air enters. There are two main types of RPE:
Contaminated air enters through cleaning filters. There are models:
Dust filters trap dust particles through electrostatic discharge, a fibrous structure.The most common filtering material for dust is FP (Petryanov filter), model "Petal" (first copy 1957) - disposable, protection against dust, aerosols.
Gas masks - contain catalysts, sorbents. Protect when working with chemicals (inorganic acids, chlorine vapors, gasoline, acetone).
Universal (combined) models have several filters that differ in functionality. Such types are considered reliable, the cost is higher than that of monofunctional models.
Respirators with anti-spark treatment, carbon filter are used for welding.
Filtering types of respirators differ in their ability to retain harmful substances - protection class, filtering activity class. It is designated by the letters FFP (abbreviation "Filtering Face Piece" - filtering half mask).
There are three classes (European standard EN-149: 2001):
The MPC value is applied - the maximum permissible concentration of impurities.
Retain 78-80% of dust, solid, liquid aerosol particles. Effectively protect if MPC (2 mg / m3) is increased by 4 times (non-toxic dust). Apply:
Protect from 92-94% of impurities, maximum concentration limit - 12 times. Used where harmful (carcinogenic) dust. Applicable:
They are used at high concentrations of toxic substances in the atmosphere. Absorb 98-99% of harmful impurities, bacteria, viruses. MPC - an increase of 30 times. Applicable:
EU countries carry out additional tests (standards EN 149: 2001 + A1: 2009). The dolomite test is carried out in a test chamber where the concentration of dolomite dust is known. The functions of high-quality respirators do not deteriorate for 8 hours (the air permeability of the product, breathing resistance is checked).
Clean air is supplied from a separate cylinder (self-contained type). Professional stand-alone models use a regenerative cartridge that purifies the inhaled air for reuse. Hose type - clean air is supplied only with a small amount of oxygen in the air used.
A respirator consists of two main parts:
Purify the air using substances:
Special protection (excess of chemical elements) is provided by cartridges with their own letter marking:
Additional elements are:
Some types of respirators have exhalation valves with a special membrane that closes when inhaling, opens when exhaling. The valve removes moist, warm air from the mask - increases efficiency, product life, cools the face (does not fog up).
Respirators protect the respiratory system in different situations:
Before choosing a respirator, it is worth deciding on the factors - working conditions, frequency of use of the product, substances that will be used.
Upcoming work will take place outdoors, where there is a low concentration of dust particles, or in a room that is well ventilated - a half mask (class FFP1, FFP2) will do. Protection of mucous eyes, ears in a closed room - a closed panoramic mask, chemical cartridges with an expiration date indicator.
Disposable models - short-term use (allergy period, door painting). Reusable types (removable filters) - frequent use (professional activity).
The type of paint used by the spray gun (painting work) - powder (anti-aerosol filter), water-based - additional protection against organic matter fumes.
You can buy any type of respirator in specialized stores (construction, with IZ products), online stores (mandatory possibility of returning goods - specifying the size, compliance with GOST).
There are three sizes (indicated on the inside, underside of the mask). You should measure the height of the face - the distance from the lower point of the chin to the large depression of the bridge of the nose (with a measuring tape).
Size 1 - less than 110 mm; 2 - 110-119 mm; 3 - more than 120 mm.
You can avoid mistakes by following the recommendations:
Moisture that accumulates under the product can be released through the valve (head should be tilted forward). If there is no valve, remove the respirator for 1-2 minutes, wipe the inside with a clean cloth.
The tightness is disturbed when wearing glasses, having a mustache, beard.
Additional tips:
A review of the best respirators was compiled based on reviews from buyers of popular Internet resources (stores, manufacturer sites). Reusable types require careful selection (size, ease of wearing, fixation).
Presented by models that cover part of the face (mouth, nose, chin). There are disposable (2-6 hours), reusable types. products.
