Increased humid­i­ty in the apart­ment wors­ens liv­ing con­di­tions, caus­es the devel­op­ment of fun­gus, mold, and the appear­ance of a musty smell. All this often leads to health prob­lems. A device for dry­ing air in the room is capa­ble of pre­vent­ing this. It will cre­ate an opti­mal micro­cli­mate for health and com­fort­able liv­ing.

Purpose of the air dryer

The rea­son for the increased humid­i­ty in the room can be var­i­ous fac­tors: the instal­la­tion of win­dow open­ings with non-com­pli­ance with stan­dards, poor hydro or ther­mal insu­la­tion, ven­ti­la­tion prob­lems. In this case, a dehu­mid­i­fi­er is used to sta­bi­lize the mois­ture lev­el. This is a unique device that can low­er and main­tain a giv­en lev­el of humid­i­ty in a res­i­den­tial area.

Depend­ing on the pur­pose, house­hold and indus­tri­al dehu­mid­i­fiers are dis­tin­guished. The main dif­fer­ence between them is pro­duc­tiv­i­ty (the amount of air processed for a cer­tain peri­od of time). The apart­ments use appli­ances for domes­tic use, which can absorb up to 50 liters of mois­ture per day, while puri­fy­ing the air from harm­ful micropar­ti­cles.

Air Dryer

The prin­ci­ple of oper­a­tion depends on the type of dehu­mid­i­fi­er device, but all of them are unit­ed by a sim­i­lar func­tion­al­i­ty: the dehu­mid­i­fi­er draws in moist air, process­es it, remov­ing excess mois­ture, and releas­es dry air back.

Types of dehumidifiers and the principle of their work

Air dehu­mid­i­fiers are clas­si­fied accord­ing to two cri­te­ria: the type of device and the prin­ci­ple of oper­a­tion.

In the first case, we are talk­ing about var­i­ous ways of installing and plac­ing the device in a res­i­den­tial area. Dehu­mid­i­fiers are floor, wall, uni­ver­sal and hid­den.

Depend­ing on the prin­ci­ple of oper­a­tion, there are adsorp­tion and con­den­sa­tion types of devices, as well as a dehu­mid­i­fi­er with the prop­er­ty of assim­i­la­tion.


The func­tion­ing of this dry­er is based on the adsorp­tion prop­er­ties of the sub­stances and mate­ri­als present in it. Inside the device there is a sor­bent that absorbs excess mois­ture, dry­ing the air inside the room. The main dis­ad­van­tage of these devices is the fre­quen­cy of chang­ing the adsor­bent.


Con­dens­ing dehu­mid­i­fiers are in the great­est demand. Such a device is the best suit­ed for a house or apart­ment.

The prin­ci­ple of oper­a­tion of the devices is based on the con­den­sa­tion of water vapor. Most home dehu­mid­i­fiers work exact­ly like an air con­di­tion­er. The device has built-in “warm” and “cold” radi­a­tors (evap­o­ra­tor and con­denser).

Floor dehumidifier

The ven­ti­lat­ed air, get­ting into the evap­o­ra­tor, is cooled. Due to this, it con­dens­es, and then accu­mu­lates in a spe­cial ves­sel (tray), from which it is nec­es­sary to reg­u­lar­ly drain the liq­uid. If this is not done, the device will auto­mat­i­cal­ly turn off.

Some mod­els of dehu­mid­i­fiers of this type have an out­let to which a pipe is con­nect­ed to drain water to the street, into the sew­er sys­tem.

With the method of assimilation

The prin­ci­ple of oper­a­tion of this type of dehu­mid­i­fi­er is the exchange of air mass­es between the room and the street. Humid air from the room is thrown out, and fresh air is drawn in from the street. Dur­ing cir­cu­la­tion, the humid­i­ty in the room decreas­es.

The dis­ad­van­tages of the device include sig­nif­i­cant heat loss, which goes out­side with moist air, as well as ener­gy costs for heat­ing the intake air. Among the dis­ad­van­tages of assim­i­la­tion-type dehu­mid­i­fiers is the inabil­i­ty of the device to dry the air in humid weath­er and the inabil­i­ty to use it in regions with a humid cli­mate.

Main selection criteria

When choos­ing a device for dehu­mid­i­fy­ing the air in an apart­ment, first of all, you should decide on the pre­ferred type.

Oth­er selec­tion cri­te­ria include the fol­low­ing:


Each device has a cer­tain per­for­mance, which indi­cates the amount of mois­ture removed per hour or day. This indi­ca­tor in the char­ac­ter­is­tics of the mod­el is indi­cat­ed in the form of abbre­vi­a­tions “l / h” or “l / s”.

If you pur­chase a device of too low pow­er, the desired effect will not be achieved and such a dehu­mid­i­fi­er will work con­tin­u­ous­ly, at the lim­it of its capa­bil­i­ties. Such a load will sig­nif­i­cant­ly reduce its ser­vice life. Buy­ing a device with a capac­i­ty that exceeds require­ments will lead to a rapid decrease in the humid­i­ty in the room, so in the future the dehu­mid­i­fi­er will only work at a loss due to ener­gy over­runs.

In order to select a device with the required per­for­mance, you should know the humid­i­ty in the room. It can be cal­cu­lat­ed as fol­lows: the area (quad­ra­ture) of the room where the air will be dried must be mul­ti­plied by a fac­tor of 0.7. You will get an approx­i­mate indi­ca­tor, which should be guid­ed by when choos­ing.

Air dryer

Noise level

When dehu­mid­i­fy­ing the air in an apart­ment, a device that is too noisy can cause dis­com­fort, espe­cial­ly when used at night. It is rec­om­mend­ed to pay atten­tion to mod­els whose noise lev­el does not exceed 45 dB.


It is rec­om­mend­ed to con­sult with a spe­cial­ist before buy­ing, which company’s device is suit­able in a par­tic­u­lar case, based on the price-qual­i­ty ratio, as well as the pop­u­lar­i­ty, reli­a­bil­i­ty and per­for­mance of the mod­els.

Water collector volume

The larg­er the vol­ume of the con­den­sate col­lec­tion tank, the less often it will have to be drained from there.

Electricity consumption

The ener­gy con­sump­tion of the dehu­mid­i­fi­er pri­mar­i­ly depends on the capac­i­ty. On the home appli­ance mar­ket, there are mod­els with a high effi­cien­cy index, which at the same time con­sume lit­tle elec­tric­i­ty.

Availability of additional functions

These include the pres­ence of a hygrom­e­ter (it dis­plays the humid­i­ty indi­ca­tor on the score­board or screen), a sound alert in case of over­flow of the water col­lec­tion tank, a timer, an air ion­iza­tion func­tion, an auto-shut­down func­tion of the device in case of incor­rect oper­a­tion or a full tank.

Also, in addi­tion, some mod­els of air dry­ers can per­form the func­tions of a hydro­stat, an air puri­fi­er.

To make the right choice and not regret the pur­chase, it is rec­om­mend­ed to care­ful­ly study the cri­te­ria for the pre­ferred mod­el.

Xenia, Moscow:

Autumn mois­ture cre­at­ed uncom­fort­able con­di­tions in the apart­ment, so rel­a­tives advised me to pur­chase a device for dry­ing the air. The choice fell on H‑DEH1-20L-UI007 Hyundai. Very easy to use, qui­et oper­a­tion and does the job. I rec­om­mend!

Oleg, Tagan­rog:

Acquired Mas­ter DH 716 three months ago. In addi­tion to the main pur­pose, he also drew atten­tion to his abil­i­ty to puri­fy the air. Con­ve­nient and easy to use. Def­i­nite­ly hap­py with the choice.

Svet­lana, Tver:

I use the Dan­Vex DEH-1000P device, I am sat­is­fied with the pur­chase. Of the “chips”, it is worth not­ing the impres­sive per­for­mance, due to which it ful­fills its direct duties to the fullest extent, and the pres­ence of a con­den­sate drainage option. The only draw­back is the high price.

A dehu­mid­i­fi­er is a device that absorbs excess mois­ture. This pre­vents the for­ma­tion of fun­gus, the appear­ance of the smell of damp­ness, which cre­ates par­tic­u­lar dis­com­fort in res­i­den­tial premis­es. The home appli­ance mar­ket offers a vari­ety of mod­els for any bud­get.
