Do-it-yourself dehumidifier for an apartment

Excessive humidity in a home negatively affects a person’s well-being; it also harms furniture, things, laminate flooring and other items. Under these conditions, fungi and mold spread, which have a detrimental effect on the respiratory system and the body’s allergic reaction. This can also provoke cancer and other serious diseases. In order to maintain an acceptable level of air humidity in your home and utility rooms, you must have a dehumidifier. The purchased device is quite expensive, but this device can be made with your own hands.

How to make a dehumidifier with your own hands

Air dehumidification devices sold in retail chains differ in functionality, level of efficiency and operational reliability. The main details of such devices:

• fan;
• evaporator;
• container for collecting water;
• capacitor;
• control Panel.

The operating principle of such devices is as follows:

1. The fan draws room air into the evaporator.
2. A sharp drop in temperature inside the device leads to the fact that the moisture in the air turns into a liquid state and flows into a collection container.
3. After filling the moisture container, it is removed from the device through drainage tubes.
4. The dried air passes through the radiator and is discharged from the device, preheated at high temperature.

It would seem that to reduce the humidity in a room, it is enough just to increase the air temperature. But this can greatly dry it out, which is just as bad as over-humidified air.

Note! The right device for drying air should not dry it out too much. For monitoring, you can put a purchased hygrometer in a homemade device.

What materials and tools will be required

To make an absorption dehumidifier with your own hands, you will need the following tools and items:

• two-liter plastic bottles - 2 pieces;
• knitting needle, needle or nail;
• box of matches or lighter;
• scissors or knife;
• scotch;
• sealant;
• scissors;
• gloves for work;
• substance for absorption;
• fan.

Silica gel is used as an absorption substance. It can be used many times, just dry it after use. At the same time, its properties are not lost. For one device, 200 g of absorbent is enough.

You can use a mobile phone charger, rechargeable battery, or regular batteries to power the fan.

Important points when assembling the device

When choosing the model of dehumidifier to assemble, you should take into account that a condensing dehumidifier not only removes high humidity, but can also reduce the air temperature by about 5 degrees. Therefore, when using it, you should turn on the heater. The installation should be carried out in such a way that the air flows intersect.

Important point! When organizing air dehumidification, you should determine the total humidity of the room so that too much dehumidification does not occur. In a room in which the humidity exceeds the threshold of 70%, dehumidification should be carried out.

A home-made device does not always have a beautiful appearance, so it is usually used for premises intended for household purposes.

Do-it-yourself dehumidifier for an apartment: step-by-step instructions

There are several options for making your own dehumidifiers. The simplest way is to make this device from plastic bottles.

Option 1

You will need 2 plastic bottles (each volume is 2 liters). Holes are made in the bottom of one of the bottles using a nail or knitting needle heated over a fire. Then it is cut crosswise with scissors, approximately in the middle.

Make holes in the top half and screw it on with a lid. Then turn it over and place it inside the bottom half. An absorbent is poured into the upper part (silica gel can be used). About 250 g of this product is enough.

The bottom of the second bottle is cut off and a fan is attached at a height of 10 cm from the edge of the bottom cut. The air stream is directed in the opposite direction from the neck. You can use a regular small fan or computer cooler.

Then another bottle with the bottom cut off is inserted into the container with the absorbent. The joints of the parts are covered with tape.

Although this device is a rather simple device, it can help cope with increased importance. Moreover, the costs of its production (time, physical and financial) are very low.

It can be placed in a children's room or bedroom.If you put a decorative cover on the bottle or do decoupage, you can get an original decorative element.

Option 2

A dehumidifier can be made from a refrigerator. The main condition is that the compressor works. All doors should be removed from it. Plexiglas is cut to the shape of the door. A hole the same size as the ventilation grille is cut out in the middle of it. The next step is to install a fan in it so that air flows into the inside of the refrigerator. This can be done using self-tapping screws. All joints must be sealed with silicone sealant.

Then small holes are drilled in the top of the plexiglass. Instead, you can attach a second fan, just put it in reverse, so that the air is blown out of the refrigerator.

A small container is placed inside the device to collect condensation moisture. To collect condensate, connect the pipe above the compressor to this container using a hose. All connections are sealed hermetically using silicone or regular tape.

Now you can turn on the dehumidifier. The fan and refrigerator are turned on simultaneously. This dehumidifier can reduce indoor humidity by about 10%. The main disadvantage is the large volume of the device.

Basement dehumidifier

To dry the air in the basement, you can make a device from materials sold in the plumbing department of the store. You should purchase a sewer tee with a diameter of 110 cm.

At the bottom of the tee, a plug is screwed in with holes made in it. There should be a threaded plug in the side hole of the inspection cover. A hole the size of the fan is made in it.You should purchase a fan with a capacity of about 95 cubic meters per hour. It is securely installed in the hole made in the plug, and screwed into the tee.

Then a metal mesh coated with fine fabric mesh is installed along the inner surface of the sewer tee. After this, the inside is filled with an adsorbent (silicon gel). This adsorbent is produced in the form of granules, inside of which there are pores. Moisture collects inside the granules. The finished device holds approximately 1 kg of silicone gel.

The finished cellar device is secured to the wall using a clamp. After installing it, you can connect it to the network. One hour of operation is enough for all the air in the basement to pass through this device.

This amount of product can absorb up to 0.5 kg of moisture from the air, which settles inside the adsorbent in 1 hour of operation. After this, the gel can be dried in the microwave by turning it on for 10 minutes, and then the product can be reused.
