Humidifier — good or bad? Overview of humidifiers


Humid­i­ty is the main indi­ca­tor of the con­tent of water vapor in the ambi­ent air and is nor­mal­ly about 55%.

It plays a huge role in our life, which we some­times do not even think about.

And neglect­ing this indi­ca­tor can be harm­ful to your health and the health of your loved ones.

The norm of humidity in the room

First of all, the need for prop­er and con­stant hydra­tion is explained by the abil­i­ty of dry air to “dehy­drate” the cells of our skin, hair, eyes. With this impact pos­si­ble devel­op­ment:

  • der­mati­tis;
  • dry­ness and peel­ing of the skin;
  • red­ness of the eyes and a burn­ing sen­sa­tion in them;
  • increased fragili­ty and dete­ri­o­ra­tion of the appear­ance of hair.

Of par­tic­u­lar impor­tance is the dry­ing of the mucous mem­brane of the res­pi­ra­to­ry tract. The mucous secret that is pro­duced to pro­tect the res­pi­ra­to­ry sys­tem ceas­es to be syn­the­sized and excret­ed, there­by reduc­ing the body’s resis­tance to path­o­gen­ic envi­ron­men­tal agents for the res­pi­ra­to­ry sys­tem.

In some cas­es an insuf­fi­cient lev­el of humid­i­ty in the room leads, on the con­trary, to an increase in the secre­tion of the mucous mem­brane of the res­pi­ra­to­ry tract, and run­ny nose and flu-like symp­toms devel­op with dif­fi­cul­ty in nasal breath­ing.

Dust con­tained in a dry room and does not set­tle due to its insuf­fi­cient mois­ture, may pro­voke aller­gic reac­tions.

In main­tain­ing nor­mal humid­i­ty and con­trol­ling its indi­ca­tors, it is sig­nif­i­cant­ly help mod­ern humid­i­fiers. Nowa­days, these appli­ances have become as com­mon as well-known stoves, microwave ovens or air con­di­tion­ers.

The main types of humidifiers


How to choose a humidifier - useful tips

In anoth­er way, this type is called devices “cold type”. Water poured into a spe­cial tank enters the pan, where car­tridges are installed for it.

With the help of a fan, dry room air is passed through these water car­tridges, humid­i­fied by evap­o­ra­tion of the liq­uid from the sur­face of the car­tridge, cleaned of dust par­ti­cles and released into the envi­ron­ment.

The advan­tage of this type is that it will nev­er over­sat­u­rate the room with mois­ture: upon reach­ing nor­mal val­ues ​​of humid­i­ty, it reduces its per­for­mance down to zero.

Its neg­a­tive fea­ture it could be con­sid­ered quick clog­ging of car­tridges when using non-dem­iner­al­ized run­ning water. Ide­al­ly, these devices should run on dis­tilled water.


This vari­ety has sim­i­lar­i­ties with elec­tric ket­tles: for humid­i­fi­ca­tion, they bring water to a boil. The liq­uid evap­o­rates in the form of steam and sat­u­rates the room with mois­ture.

Humidifiers: information for dummies |  pokupkaprosto.ruAmong the plus­es steam humid­i­fiers emit:

  • high per­for­mance;
  • the abil­i­ty to work on any kind of water, unlike cold.

But there are also a num­ber of dis­ad­van­tages:

  • high noise lev­el dur­ing oper­a­tion
  • release of hot steam, which pos­es a risk of burns.

The high pow­er of the steam device is both its plus and minus, because at the same time it ensures its more effi­cient oper­a­tion and con­sumes a lot of elec­tric­i­ty.


The most pop­u­lar and per­fect mod­el, dif­fer­ent from the rest by the mech­a­nism of its work: with the help of ultra­sound, they turn the fluc­tu­a­tions of elec­tric­i­ty into vibra­tion, which helps in the for­ma­tion of fine water dust. Ultrasonic humidifier with ionization AIC SPS-

After that, this dust pass­es almost at the very exit from the device into a vapor state and nor­mal­izes the humid­i­ty in the room.

Ultra­son­ic humid­i­fiers have a large num­ber of advan­tages:

  • low pow­er;
  • small sizes;
  • com­pact­ness;
  • con­ve­nience in oper­a­tion.

But, as for the clas­sic ones, dis­tilled water is the best in their use.

Air wash

These devices car­ry out their work through process­es that are as close as pos­si­ble to the nat­ur­al evap­o­ra­tion of the liq­uid.

Air washing

With indoor fan air pass­es through spe­cial­ized drums clean­er, pre­vi­ous­ly moist­ened with water. At this moment every­thing dust par­ti­cles, mix­ing with water droplets, set­tle in themthe air itself is sat­u­rat­ed with mois­ture, and then returns to the room.

With the help of sinks, water­log­ging can be avoid­ed, they have:

  • low ener­gy con­sump­tion;
  • low noise lev­el dur­ing oper­a­tion.

But in terms of size and price, this type is sig­nif­i­cant­ly supe­ri­or to oth­ers, which is its main dis­ad­van­tage.

The benefits of a humidifier: which one is better to choose

device for a child

Favor­able action Obvi­ous­ly, it is espe­cial­ly man­i­fest­ed in rela­tion to chil­dren. Because of chil­dren’s mech­a­nisms of ther­moreg­u­la­tion are imper­fectand the metab­o­lism goes with some greater inten­si­ty than in adults, the nor­mal val­ues ​​​​of humid­i­ty:

  • help to avoid over­heat­ing or hypother­mia of the child (since dry air increas­es, and excess mois­ture low­ers body tem­per­a­ture),
  • pre­vent the occur­rence of acute res­pi­ra­to­ry dis­eases and aller­gies,
  • enhance the readi­ness of the body to give an immune response to path­o­gen­ic stim­uli.

There­fore, it is nec­es­sary to use a chil­dren’s air humid­i­fi­er.

For adults, this is no less impor­tant than for kids. In addi­tion to the same ben­e­fits in rela­tion to the body’s immune sys­tem and the pre­ven­tion of ARI,

  • gen­er­al well-being improves,
  • relieves fatigue after a hard day at work,
  • reduces the risk of devel­op­ing der­mati­tis or con­junc­tivi­tis.

But not only for peo­ple These devices are use­ful:

  • nor­mal humid­i­ty helps to pre­serve wood­en fur­ni­ture and oth­er envi­ron­men­tal items,
  • Helps plant growth and pho­to­syn­the­sis.

It is the ben­e­fi­cial effect on the pro­duc­tion of oxy­gen by plants that replen­ish­es its reserves in the room, which means breathe eas­i­er in the room. Main­tain­ing nor­mal humid­i­ty pro­vides a bal­ance of heat trans­fer and heat pro­duc­tion, which explains the feel­ing of ther­mal com­fort in such rooms.

Harm from using humidifiers

First of all, it is asso­ci­at­ed with the design fea­tures and indi­vid­ual com­po­nents of the device.

Humidifier - benefits and harms? For exam­ple, cold machines accu­mu­late many microor­gan­isms on their car­tridgeswhich, when the car­tridge is changed irreg­u­lar­ly, are released into the envi­ron­ment along with recy­cled air.

You can eas­i­ly get burned from a steam appli­ance, it also con­tributes to an increase in the tem­per­a­ture in the room due to the evap­o­ra­tion process, which is espe­cial­ly unfa­vor­able for peo­ple with dis­eases of the car­dio­vas­cu­lar sys­tem.

Ultra­son­ic Humid­i­fi­er Caus­es Harmwhen all those sub­stances that were dis­solved in the water used for humid­i­fi­ca­tion are released into the envi­ron­ment along with the air. All these com­pounds are able to get both into the organs of the human res­pi­ra­to­ry sys­tem and remain on the fur­nish­ings in a set­tled form.

  • Excess mois­ture pro­motes the devel­op­ment of fun­gus on the walls,
  • adverse­ly affects wood­en house­hold items,
  • increas­es the body’s sus­cep­ti­bil­i­ty to acute res­pi­ra­to­ry infec­tions and dis­rupts ther­moreg­u­la­to­ry func­tion.

A per­son will be exposed to hypother­mia and increased micro­bial expo­sure.

How to use a humidifier

  • Before use any kind of device Please read the enclosed instruc­tions care­ful­ly.
  • Installing the instru­ment must only be car­ried out on a lev­el and sta­ble sur­face so that the device does not fall or be tilt­ed dur­ing oper­a­tion.
  • Be aware of the jet of hot steam when using a steam humid­i­fi­er and risk of burns.
  • It is not rec­om­mend­ed to install the device close to the wall, fur­ni­ture, oth­er elec­tron­ic devices, as it can sim­ply ruin them.
  • If white deposits appear on fur­ni­ture, sim­ply change the car­tridges or water in the appli­ance more often, it is also advised to gen­er­al­ly switch to dis­tilled water, which does not give such a raid.

In addi­tion to humid­i­fiers, oth­er meth­ods of humid­i­fi­ca­tion are wide­ly applic­a­ble, but this requires the use of spe­cial devices for mea­sur­ing humid­i­ty — hygrom­e­ters.

Their use is due to the fact that the humid­i­fi­er usu­al­ly already has a humid­i­ty sen­sor with a hygrom­e­terand oth­er meth­ods need to be sup­ple­ment­ed with this device sep­a­rate­ly.

To main­tain nor­mal humid­i­ty, ven­ti­late the room reg­u­lar­ly, spray water with a spray bot­tle if nec­es­sary, increase the num­ber of indoor plants or put a dec­o­ra­tive foun­tain.
